A practical guide to the care of ingrown toenails
CASE
A 22-year-old active-duty man presented with left hallux pain, which he had experienced for several years due to an “ingrown toenail.” During the 3 to 4 months prior to presentation, his pain had progressed to the point that he had difficulty with weight-bearing activities. Several weeks prior to evaluation, he tried removing a portion of the nail himself with nail clippers and a pocket knife, but the symptoms persisted.
A skin exam revealed inflamed hypertrophic skin on the medial and lateral border of the toenail without exudate (FIGURE 1A). The patient was given a diagnosis of recurrent onychocryptosis without paronychia. He reported having a similar occurrence 1 to 2 years earlier, which had been treated by his primary care physician via total nail avulsion.
How would you proceed with his care?
Onychocryptosis, also known as an ingrown toenail, is a relatively common condition that can be treated with several nonsurgical and surgical approaches. It occurs when the nail plate punctures the periungual skin, usually on the hallux. Onychocryptosis may be caused by close-trimmed nails with a free edge that are allowed to enter the lateral nail fold. This results in a cascade of inflammatory and infectious processes and may result in paronychia. The inflamed toe skin will often grow over the lateral nail, which further exacerbates the condition. Mild to moderate lesions have limited pain, redness, and swelling with little or no discharge. Moderate to severe lesions have significant pain, redness, swelling, discharge, and/or persistent symptoms despite appropriate conservative therapies.
The condition may manifest at any age, although it is more common in adolescents and young adults. Onychocryptosis is slightly more common in males.1 It may present as a chief complaint, although many cases will likely be discovered incidentally on a skin exam. Although there is no firm evidence of causative factors, possible risk factors include tight-fitting shoes, repetitive activities/sports, poor foot hygiene, hyperhidrosis, genetic predisposition, obesity, and lower-extremity edema.2 Patients often exacerbate the problem with home treatments designed to trim the nail as short as possible. Comparison of symptomatic vs control patients has failed to demonstrate any systematic difference between the nails themselves. This suggests that treatment may not be effective if it is simply directed at controlling nail abnormalities.3,4
Conservative therapy
Conservative therapy should be considered first-line treatment for mild to moderate cases of onychocryptosis. The following are conservative therapy options.5
Proper nail trimming. Advise the patient to allow the nail to grow past the lateral nail fold and to keep it trimmed long so that the overgrowing toe skin cannot encroach on the free edge of the nail. The growth rate of the toenail is approximately 1.62 mm/month—something you may want to mention to the patient so that he or she will have a sense of the estimated duration of therapy.6 Also, the patient may need to implement the following other measures, while the nail is allowed to grow.
Continue to: Skin-softening techniques
Skin-softening techniques. Encourage the patient to apply warm compresses or to soak the toe in warm water for 10 to 20 minutes a day.
Barriers may be inserted between the nail and the periungual skin. Daily intermittent barriers may be used to lift the nail away from the lateral nail fold during regular hygiene activities. Tell the patient that a continuous barrier may be created using gauze or any variety of dental floss placed between the nail and the lateral nail fold, then secured in place with tape and changed daily.
Gutter splint. The gutter splint consists of a plastic tube that has been slit longitudinally from bottom to top with iris scissors or a scalpel. One end is then cut diagonally for smooth insertion between the nail edge and the periungual skin. When placed, the gutter splint lies longitudinally along the edge of the nail, providing a barrier to protect the toe during nail growth. The tube may be obtained by trimming a sterilized vinyl intravenous drip infusion, the catheter from an 18-gauge or larger needle (with the needle removed), or a filter straw. This tube can be affixed with adhesive tape, sutures, or cyanoacrylate.7
Patient-controlled taping. An adhesive tape such as 1-inch silk tape is placed on the symptomatic edge of the lateral nail fold and traction is applied. The tape is then wrapped around the toe and affixed such that the lateral nail fold is pulled away from the nail.8
Medications. Many practitioners use high-potency topical steroids, although evidence for their effectiveness is lacking. Oral antibiotics are unnecessary.

One disadvantage of conservative therapy is that the patient must wait for nail growth before symptom resolution is achieved. In cases where the patient requires immediate symptom resolution, surgical therapies can be used (such as nail edge excision).
Surgical therapy
Surgery is more effective than nonsurgical therapies in preventing recurrence2,9 and is indicated for severe cases of onychocryptosis or for patients who do not respond to a trial of at least 3 months of conservative care.
While there are no universally accepted contraindications to surgical toenail procedures, caution should be taken with patients who have poor healing potential of the feet (eg, chronic vasculopathy or neuropathy). That said, when patients with diabetes have undergone surgical toenail procedures, the research indicates that they have not had worse outcomes.10,11
The following options for surgical therapy of onychocryptosis are considered safe; however, each has variable effectiveness. Each procedure should be performed under local anesthesia, typically as a digital nerve block. The toe should be cleansed prior to any surgical intervention, and clean procedure precautions should be employed. Of the procedures listed here, only phenolization and the Vandenbos procedure are considered definitive treatments for onychocryptosis.5
Total nail removal without matricectomy. In this procedure, the nail is removed entirely, but the nail matrix is not destroyed. The nail regrows in the same dimensions as it had previously, but during the time it is absent the nail bed tends to contract longitudinally and transversely, increasing the likelihood that new nail growth will cause recurrence of symptoms.5 Due to a recurrence rate of > 70%, total nail removal without matricectomy is not recommended as monotherapy for ingrown toenails.9
Continue to: Nail edge excision without mactricectomy
Nail edge excision without matricectomy. This procedure involves removing one-quarter to one-third of the nail from the symptomatic edge. This procedure takes little time and is easy to perform. Recurrence rates are > 70% for the same reasons as outlined above.9 (Often during preparation for this procedure, a loose shard of nail is observed puncturing the periungual skin. Removal of this single aberrant portion of nail is frequently curative in and of itself.) Patients typically report rapid relief of symptoms, so this procedure may be favored when patients do not have the time or desire to attempt more definitive therapy. However, patients should be advised of the high recurrence rate.
Nail excision with matricectomy using phenol (ie, phenolization). In this procedure, the nail is avulsed, and the matrix is destroyed with phenol (80%-88%).9,12 Typically, this is performed only on the symptomatic edge of the nail. The phenol should be applied for 1 to 3 minutes using a cotton-tipped applicator saturated in the solution.
While phenolization is relatively quick and simple—and is associated with good cure rates—it causes pain and disability during the healing process and takes several weeks to heal. Phenolization also has a slightly increased risk for infection when compared to nail excision without matricectomy. Giving antibiotics before or following the procedure does not appear to reduce this risk.7 If the matrix is incompletely destroyed, a new nail spicule may grow along the lateral nail edge and a repeat procedure may be required.7 When properly performed, the nail will be narrower but should otherwise maintain a more-or-less normal appearance. The use of phenolization for the treatment of onychocryptosis in the pediatric population has been found to be successful, as well.14
The Vandenbos procedure. This procedure involves removing a large amount of skin from the lateral nail fold and allowing it to heal secondarily. When performed correctly, this procedure has a very low recurrence rate, with no cases of recurrence in nearly 1200 patients reported in the literature.15 The cosmetic results are generally superior to the other surgical methods described here5 and patient satisfaction is high.15 It has been used with similar effectiveness in children.16
Full recovery takes about 6 weeks. Overall, the Vandenbos procedure can definitively treat the condition with a good cosmetic outcome. (See “How to perform the Vandenbos procedure.”)

How to perform the Vandenbox procedure
The Vandenbos procedure, also known as soft-tissue nail fold excision, was first described in 1958 by Kermit Q. Vandenbos, a surgeon for the US Air Force. He felt that overgrown toe skin was the primary causative factor in onychocryptosis.4
In the procedure, the hypertrophic skin is removed to such a degree that it cannot encroach on the growing nail. After the toe is fully healed, the toe and nail should have a fully normal appearance. Indications and contraindications are the same as for other surgical procedures for the treatment of onychocryptosis. Pain and disability following the procedure is similar to phenolization, and the recovery period takes several weeks for the patient to fully heal.
Equipment needed:
- alcohol swab
- tourniquet (optional)
- 3 mL to 5 mL of local anesthetic (eg, 2% lidocaine)
- topical antiseptic (eg, iodine or chlorhexidine)
- number 15 blade scalpel
- tissue forceps
- cautery device (electrocautery or thermocautery)
- dressing supplies (topical ointment, gauze, tape)
The steps15:
- Perform a digital nerve block using an alcohol swab and anesthetic. The anesthetic may be used with or without epinephrine.
- Place a tourniquet at the base of the toe if the anesthetic does not contain epinephrine. The tourniquet is not required if epinephrine is used during anesthesia.17
- Cleanse the toe with iodine, chlorhexidine, or a similar agent.
- Make a 5-mm incision proximally while leaving the nail bed intact. Begin approximately 3 mm from the lateral edge of the base of the nail. The incision should extend around the edge of the toe in an elliptical sweep towards the tip of the nail, remaining 3 mm from the edge of the nail. This is best accomplished in a single motion with a #15 blade. An adequate portion of skin must be removed, leaving a defect of approximately 1.5 × 3 cm (approximately the size of a cashew) (FIGURE 1B).
- Electrocauterize or thermocauterize along the edges and subcutaneous tissue of the wound. This reduces postoperative bleeding and pain. The matrix should not be damaged.
- Dress the wound with ample amounts of petrolatum followed by nonstick gauze. Profuse bleeding can be expected unless pressure is applied, so apply ample amounts of additional gauze to absorb any blood. The foot is elevated and the tourniquet (if used) removed. In order to reduce postoperative bleeding and pain, instruct the patient to lie with the foot elevated as much as possible for the first 24 to 48 hours.
- Advise the patient that moderate pain is expected for the first 2 to 3 days. Analgesia may be obtained with an acetaminophen/opiate combination (eg, hydrocodone/acetaminophen 5/325, 1 tablet every 4-6 hours as needed) for the first 2 to 3 days. This may be followed by acetaminophen or nonsteroidal anti-inflammatory drugs thereafter at usual dosing, which can either be prescribed or obtained over the counter.
Postoperative care
After 48 hours, the patient can remove the dressing and gently rinse the wound and reapply a new dressing as before. The dressing should be changed at least once daily and whenever it becomes soiled or wet. After 48 hours, while the dressing remains on the toe, the patient may begin taking brief showers. After showering, the toe should be gently rinsed with clean water and the dressing changed. Blood or crust should not be scrubbed off, as this will impair re-epithelialization, but it may be rinsed off if able. Otherwise, the wound should not be soaked until re-epithelialization has occurred.
Patient follow-up should occur after 1 to 2 weeks (FIGURE 1C). After approximately 6 weeks, the wound should be healed completely with the nail remaining above the skin. (FIGURE 1D shows wound healing after 3 months.)
Advise patients that erythema and drainage are expected, but the erythema should not extend proximally from the metatarsophalangeal joint. Prophylactic antibiotics are not required, although they may be used if infection is suspected. Despite the proximity of the procedure to the distal phalanx, there have been no reported cases of osteomyelitis.15

Of the procedures listed here, only phenolization and the Vandenbos procedure are considered definitive treatments for onychocryptosis.5
Total nail removal without matricectomy. In this procedure, the nail is removed entirely, but the nail matrix is not destroyed. The nail regrows in the same dimensions as it had previously, but during the time it is absent the nail bed tends to contract longitudinally and transversely, increasing the likelihood that new nail growth will cause recurrence of symptoms.5 Due to a recurrence rate of > 70%, total nail removal without matricectomy is not recommended as monotherapy for ingrown toenails.9
Continue to: Nail edge excision without mactricectomy
Nail edge excision without matricectomy. This procedure involves removing one-quarter to one-third of the nail from the symptomatic edge. This procedure takes little time and is easy to perform. Recurrence rates are > 70% for the same reasons as outlined above.9 (Often during preparation for this procedure, a loose shard of nail is observed puncturing the periungual skin. Removal of this single aberrant portion of nail is frequently curative in and of itself.) Patients typically report rapid relief of symptoms, so this procedure may be favored when patients do not have the time or desire to attempt more definitive therapy. However, patients should be advised of the high recurrence rate.
Nail excision with matricectomy using phenol (ie, phenolization). In this procedure, the nail is avulsed, and the matrix is destroyed with phenol (80%-88%).9,12 Typically, this is performed only on the symptomatic edge of the nail. The phenol should be applied for 1 to 3 minutes using a cotton-tipped applicator saturated in the solution.
While phenolization is relatively quick and simple—and is associated with good cure rates—it causes pain and disability during the healing process and takes several weeks to heal. Phenolization also has a slightly increased risk for infection when compared to nail excision without matricectomy. Giving antibiotics before or following the procedure does not appear to reduce this risk.7 If the matrix is incompletely destroyed, a new nail spicule may grow along the lateral nail edge and a repeat procedure may be required.7 When properly performed, the nail will be narrower but should otherwise maintain a more-or-less normal appearance. The use of phenolization for the treatment of onychocryptosis in the pediatric population has been found to be successful, as well.14
The Vandenbos procedure. This procedure involves removing a large amount of skin from the lateral nail fold and allowing it to heal secondarily. When performed correctly, this procedure has a very low recurrence rate, with no cases of recurrence in nearly 1200 patients reported in the literature.15 The cosmetic results are generally superior to the other surgical methods described here5 and patient satisfaction is high.15 It has been used with similar effectiveness in children.16
Full recovery takes about 6 weeks. Overall, the Vandenbos procedure can definitively treat the condition with a good cosmetic outcome. (See “How to perform the Vandenbos procedure.”)

How to perform the Vandenbox procedure
The Vandenbos procedure, also known as soft-tissue nail fold excision, was first described in 1958 by Kermit Q. Vandenbos, a surgeon for the US Air Force. He felt that overgrown toe skin was the primary causative factor in onychocryptosis.4
In the procedure, the hypertrophic skin is removed to such a degree that it cannot encroach on the growing nail. After the toe is fully healed, the toe and nail should have a fully normal appearance. Indications and contraindications are the same as for other surgical procedures for the treatment of onychocryptosis. Pain and disability following the procedure is similar to phenolization, and the recovery period takes several weeks for the patient to fully heal.
Equipment needed:
- alcohol swab
- tourniquet (optional)
- 3 mL to 5 mL of local anesthetic (eg, 2% lidocaine)
- topical antiseptic (eg, iodine or chlorhexidine)
- number 15 blade scalpel
- tissue forceps
- cautery device (electrocautery or thermocautery)
- dressing supplies (topical ointment, gauze, tape)
The steps15:
- Perform a digital nerve block using an alcohol swab and anesthetic. The anesthetic may be used with or without epinephrine.
- Place a tourniquet at the base of the toe if the anesthetic does not contain epinephrine. The tourniquet is not required if epinephrine is used during anesthesia.17
- Cleanse the toe with iodine, chlorhexidine, or a similar agent.
- Make a 5-mm incision proximally while leaving the nail bed intact. Begin approximately 3 mm from the lateral edge of the base of the nail. The incision should extend around the edge of the toe in an elliptical sweep towards the tip of the nail, remaining 3 mm from the edge of the nail. This is best accomplished in a single motion with a #15 blade. An adequate portion of skin must be removed, leaving a defect of approximately 1.5 × 3 cm (approximately the size of a cashew) (FIGURE 1B).
- Electrocauterize or thermocauterize along the edges and subcutaneous tissue of the wound. This reduces postoperative bleeding and pain. The matrix should not be damaged.
- Dress the wound with ample amounts of petrolatum followed by nonstick gauze. Profuse bleeding can be expected unless pressure is applied, so apply ample amounts of additional gauze to absorb any blood. The foot is elevated and the tourniquet (if used) removed. In order to reduce postoperative bleeding and pain, instruct the patient to lie with the foot elevated as much as possible for the first 24 to 48 hours.
- Advise the patient that moderate pain is expected for the first 2 to 3 days. Analgesia may be obtained with an acetaminophen/opiate combination (eg, hydrocodone/acetaminophen 5/325, 1 tablet every 4-6 hours as needed) for the first 2 to 3 days. This may be followed by acetaminophen or nonsteroidal anti-inflammatory drugs thereafter at usual dosing, which can either be prescribed or obtained over the counter.
Postoperative care
After 48 hours, the patient can remove the dressing and gently rinse the wound and reapply a new dressing as before. The dressing should be changed at least once daily and whenever it becomes soiled or wet. After 48 hours, while the dressing remains on the toe, the patient may begin taking brief showers. After showering, the toe should be gently rinsed with clean water and the dressing changed. Blood or crust should not be scrubbed off, as this will impair re-epithelialization, but it may be rinsed off if able. Otherwise, the wound should not be soaked until re-epithelialization has occurred.
Patient follow-up should occur after 1 to 2 weeks (FIGURE 1C). After approximately 6 weeks, the wound should be healed completely with the nail remaining above the skin. (FIGURE 1D shows wound healing after 3 months.)
Advise patients that erythema and drainage are expected, but the erythema should not extend proximally from the metatarsophalangeal joint. Prophylactic antibiotics are not required, although they may be used if infection is suspected. Despite the proximity of the procedure to the distal phalanx, there have been no reported cases of osteomyelitis.15

Sleep, chronic pain, and OUD have a complex relationship
MILWAUKEE – Individuals with chronic pain frequently have disrupted sleep and also may be at risk for opioid use disorder. However, even with advanced monitoring, it’s not clear how sleep modulates pain and opioid cravings.
Sleep has an impact on positive and negative affect, but new research shows that the link between sleep and mood states that may contribute to opioid use disorder is not straightforward. At the scientific meeting of the American Pain Society, Patrick Finan, PhD, of Johns Hopkins University, Baltimore, discussed how sleep and mood affect cravings for opioids among those in treatment for opioid use disorder (OUD).
said Dr. Finan, who told attendees that one key question he and his colleagues were seeking to answer was whether those with OUD and chronic pain had more disturbed sleep than those with OUD alone. Also, the researchers wanted to know whether the ups and downs of sleep on a day-to-day basis were reflected in pain scores among those with OUD, as would be predicted by prevailing models.
Finally, two “proximal indicators” of relapse risk, affect and heroin craving, might be affected by both sleep and pain, and Dr. Finan and collaborators sought to explore that association.
The work was part of a larger study looking at the natural history of OUD and OUD with comorbid chronic pain. To participate in this parent study, adults with OUD had to be seeking treatment or currently enrolled in methadone or buprenorphine maintenance treatment, and without current major depressive disorder. Also, patients could not have a history of significant mental illness, cognitive impairment, or a medical condition that would interfere with study participation. A total of 56 patients participated, and 20 of these individuals also had chronic pain.
Those with OUD and chronic pain qualified if they had pain (not related to opioid withdrawal) averaging above 3 on a 0-10 pain rating scale over the past week; additional criteria included pain for at least the past 3 months, with 10 or more days per month of pain.
Pain ratings were captured via a smartphone app that prompted participants to enter a pain rating at three random times during each day. Each evening, patients also completed a sleep diary giving information about bedtime, sleep onset latency, waking after sleep onset, and wake time for the preceding day.
A self-applied ambulatory electroencephalogram applied to the forehead was used for up to 7 consecutive nights to capture sleep continuity estimates; the device has been validated against polysomnography data in other work. Participants were given incentives to use the device, and this “yielded strong adherence,” with an average of 5 nights of use per participant, Dr. Finan said.
Patients were an average age of about 49 years, and were 75% male. African American participants made up just over half of the cohort, and 43% were white. Participants were roughly evenly divided in the type of maintenance therapy they were taking. Overall, 39% of participants had a positive urine toxicology screen.
For patients with chronic pain, 45% of all momentary pain reports had a pain score over zero, with a mean of 32 days of pain. Looking at the data another way, 58% of all patient-days had at least one momentary report of pain greater than zero, said Dr. Finan. On average, participants recorded a pain score of 2.27.
Brief Pain Inventory scores at baseline showed a mean severity of 5, and a pain interference score of 5.07.
Participants with OUD and chronic pain did not differ across any EEG-recorded sleep measures, compared with those with OUD alone. However, subjective reports of sleep were actually better overall for those with chronic pain than the objective EEG reports. The EEG recordings captured an average of 9.11 minutes more of waking after sleep onset (P less than .001). Also, total sleep time was 10.37 minutes shorter as recorded by the EEG than by self-report (P less than .001). Overall sleep efficiency was also worse by 5.96 minutes according to the EEG, compared with self-report (P less than .001).
“Sleep is objectively poor but subjectively ‘normal’ and variable in opioid use disorder patients,” Dr. Finan said. In aggregate, however, neither diary-based subjective nor EEG-based objective sleep measures differed between those with and without chronic pain in the research cohort. This phenomenon of sleep efficiency being self-reported as higher than objective measures capture sleep has also been seen in those newly abstinent from cocaine, Dr. Finan said, adding that it’s possible individuals with substance use disorder who are new to treatment simply feel better than they have in some time along many dimensions, with sleep being one such domain.
Pain on a given day didn’t predict poor sleep on that night, except that sleep onset took slightly longer (P = .01), said Dr. Finan. He noted that “there was no substantive effect on other sleep continuity parameters.”
Looking at how negative affect mediated craving for heroin, Dr. Finan and colleagues found that negative affect–related craving was significantly greater for those with chronic pain (P less than .001). Unlike findings in patients without OUD, having disrupted sleep continuity was more associated with increased daily negative affect, rather than decreased positive affect. And this increased negative affect was associated with heroin cravings, said Dr. Finan. “In the past few years, we’ve seen quite a few studies that have found some abnormalities in the reward system in patients with chronic pain.” Whether poor sleep is a mediator of these abnormalities deserves further study.
The study was supported by the National Institutes of Health. Dr. Finan reported no outside sources of funding.

REPORTING FROM APS 2019
Direct pharmacy dispensing of naloxone linked to drop in fatal overdoses
investigators reported.
By contrast, state laws that stopped short of allowing pharmacists to directly dispense the opioid antagonist did not appear to impact mortality, according to the report, which appears in JAMA Internal Medicine (2019 May 6. doi: 10.1001/jamainternmed.2019.0272).
The report, based on state-level trends tracked from 2005 to 2016, indicates that fatal opioid overdoses fell by nearly one-third in states that adopted direct dispensing laws as compared with states that adopted other naloxone laws.
That finding suggests that the policy type determines whether a naloxone law is useful in combating fatal opioid overdoses, said Rahi Abouk, PhD, of William Paterson University, Wayne, N.J. and co-authors of the paper.
“Enabling distribution through various sources, or requiring gatekeepers, will not be as beneficial,” Dr. Abouk and co-authors said in their report.
The current rate of deaths from fentanyl, heroin, and prescription analgesic overdose has outpaced all previous drug epidemics on record, and even surpasses the number of deaths in the peak year of the HIV epidemic of the 1980s, Dr. Abouk and colleagues wrote in their paper.
The number of states with naloxone access laws grew from just 2 in 2005 to 47 by 2016, including 9 states that granted direct authority to pharmacists and 38 that granted indirect authority, according to the researchers.
The analysis of overdose trends from 2005 to 2016 was based on naloxone distribution data from state Medicaid agencies and opioid-related mortality data from a national statistics system. Forty percent of nonelderly adults with an opioid addiction are covered by Medicaid, the researchers said.
They found that naloxone laws granting pharmacists direct dispensing authority were linked to a drop in opioid deaths that increased in magnitude over time, according to researchers. The mean number of opioid deaths dropped by 27% in the second year after adoption of direct authority laws, relative to opioid deaths in states with indirect access laws, while in subsequent years, deaths dropped by 34%.
Emergency department visits related to opioids increased by 15% in direct authority states 3 or more years after adoption, as compared to states that did not adopt direct authority laws. According to investigators, that translated into 15 additional opioid-related emergency department visits each month.
That increase suggests that, alongside direct dispensing laws, “useful interventions” and connections to treatment are needed for the emergency department, according to Dr. Abouk and colleagues.
“This is the location where such programs may be the most effective,” they said in their report.
Future research should be done to determine whether removing gatekeepers increases the value of naloxone distribution policies, they concluded in the report.
Dr. Abouk had no disclosures. Co-authors on the study reported funding and conflict of interest disclosures related to the National Institute on Drug Abuse and the Centers for Disease Control and Prevention.

By contrast, state laws that stopped short of allowing pharmacists to directly dispense the opioid antagonist did not appear to impact mortality, according to the report, which appears in JAMA Internal Medicine (2019 May 6. doi: 10.1001/jamainternmed.2019.0272).
The report, based on state-level trends tracked from 2005 to 2016, indicates that fatal opioid overdoses fell by nearly one-third in states that adopted direct dispensing laws as compared with states that adopted other naloxone laws.
That finding suggests that the policy type determines whether a naloxone law is useful in combating fatal opioid overdoses, said Rahi Abouk, PhD, of William Paterson University, Wayne, N.J. and co-authors of the paper.
“Enabling distribution through various sources, or requiring gatekeepers, will not be as beneficial,” Dr. Abouk and co-authors said in their report.
The current rate of deaths from fentanyl, heroin, and prescription analgesic overdose has outpaced all previous drug epidemics on record, and even surpasses the number of deaths in the peak year of the HIV epidemic of the 1980s, Dr. Abouk and colleagues wrote in their paper.
The number of states with naloxone access laws grew from just 2 in 2005 to 47 by 2016, including 9 states that granted direct authority to pharmacists and 38 that granted indirect authority, according to the researchers.
The analysis of overdose trends from 2005 to 2016 was based on naloxone distribution data from state Medicaid agencies and opioid-related mortality data from a national statistics system. Forty percent of nonelderly adults with an opioid addiction are covered by Medicaid, the researchers said.
They found that naloxone laws granting pharmacists direct dispensing authority were linked to a drop in opioid deaths that increased in magnitude over time, according to researchers. The mean number of opioid deaths dropped by 27% in the second year after adoption of direct authority laws, relative to opioid deaths in states with indirect access laws, while in subsequent years, deaths dropped by 34%.
Emergency department visits related to opioids increased by 15% in direct authority states 3 or more years after adoption, as compared to states that did not adopt direct authority laws. According to investigators, that translated into 15 additional opioid-related emergency department visits each month.
That increase suggests that, alongside direct dispensing laws, “useful interventions” and connections to treatment are needed for the emergency department, according to Dr. Abouk and colleagues.
“This is the location where such programs may be the most effective,” they said in their report.
Future research should be done to determine whether removing gatekeepers increases the value of naloxone distribution policies, they concluded in the report.

Arthritis joint pain, inactivity vary greatly across U.S.
Almost 31% of the estimated 54 million adults in the United States with arthritis have severe joint pain, according to the Centers for Disease Control and Prevention.
Nationally, the prevalence of severe joint pain was 30.8% in adults with arthritis in 2017, but state-specific, age-standardized prevalences varied from a low of 20.8% in Colorado to 45.2% in Mississippi. Regionally, prevalences of both severe joint pain and physical inactivity in arthritis patients were highest in the Southeast, noted Dana Guglielmo, MPH, of the CDC’s National Center for Chronic Disease Prevention and Health Promotion, Atlanta, and associates (MMWR 2019 May 3;68(17):381-7).
The prevalence of arthritis itself was lowest in the District of Columbia at 15.7% and highest in West Virginia at 34.6%. Alabama, at 30.4%, was the only other state above 30%. Colorado had the lowest physical inactivity rate (23.2%), while Kentucky had the highest (44.4%), the investigators said.
The differences among arthritis patients were demographic as well as geographic in 2017. The prevalence of severe joint pain was 33.0% among those aged 18-44 years and 35.6% in those 45-64 but only 25.1% in those aged 65 and older. Whites had a 27.4% prevalence of severe joint pain, compared with 42.0% for Hispanics and 50.9% for blacks. For arthritis patients with a college degree, the age-standardized prevalence of severe joint pain was 15.1%, compared with 35.5% for high school graduates and 54.1% for those with less than a high school degree, based on data from the Behavioral Risk Factor Surveillance System.
“Although persons with arthritis report that pain, or fear of causing or worsening it, is a substantial barrier to exercising, physical activity is an inexpensive intervention that can reduce pain, prevent or delay disability and limitations, and improve mental health, physical functioning, and quality of life with few adverse effects,” wrote Ms. Guglielmo and associates. Adults with severe joint pain “should engage in regular physical activity according to their abilities and avoid physical inactivity [since] even small amounts of physical activity can improve physical functioning in adults with joint conditions.”

What do patients want in a migraine preventive?
, according to the results of a study published in Headache. When offered hypothetical preventive migraine medicines with a wide array of attributes, patients leaned toward those with a reduction in migraine days and an avoidance of weight gain, according to an analysis of responses to a discrete-choice experiment survey.
“We found that respondents had a significant willingness to pay for medicines with higher efficacy and less-severe adverse events,” wrote Carol Mansfield, PhD, of RTI Health Solutions in North Carolina, and coauthors.
To evaluate patient preferences for theoretical migraine medicine, the researchers conducted a discrete-choice experiment via a web-based survey. Respondents met eligibility criteria if they were adults aged 18 years or older who self-reported 6 or more migraine days per month and completed the survey in full. They were asked to choose between options defined by six attributes: reduction in headache days per month, frequency of limitations with physical activities, cognition problems, weight gain, how the medicine is taken, and monthly out-of-pocket cost.
Of the 300 respondents included in the analysis, 72% indicated that migraines make physical activities difficult all or most of the time, and 81% had taken a prescription migraine preventive in the last 6 months. Respondents reported, on average, approximately 16 headache days per month. Among noncost attributes, respondents valued a change from a 10% reduction in migraine days to a 50% reduction more highly than avoiding the worst levels of adverse events – defined as memory problems and 10% weight gain – but were willing to trade off efficacy for less-severe adverse events. Avoiding memory problems was more important than avoiding thinking problems. Avoiding a 10% weight gain was more important than avoiding thinking and memory problems. Respondents preferred a once-monthly injection or daily pill to twice-monthly injections. Respondents, on average, were willing to pay $116 per month for an improvement from 10% to 50% in reduced headache days (95% confidence interval [CI], $91-$141) and $43 for an improvement from 10% to 25% (95% CI, $34-$53). They were also willing to pay $84 per month to avoid a 10% weight gain (95% CI, $64-$103), $59 per month to avoid memory problems (95% CI, $42-$76), and $32 per month to avoid thinking problems (95% CI, $18-$46).
The coauthors acknowledged their study’s limitations, including all migraine diagnoses being self-reported and the study sample not necessarily being representative of patients with migraine overall. In addition, though the potential medicinal attributes used were prominent in clinical literature and focus groups, they could choose only a limited amount and so their analysis “did not address other attributes that may be important to patients.”
Given their findings, the researchers recommended that “clinicians should work with patients to select treatments that meet each patient’s needs.”
Amgen and Novartis funded the study. The authors reported numerous conflicts of interest, including receiving grants, consulting fees, and royalties from pharmaceutical companies and organizations. During the study, three of the authors were employed at RTI Health Solutions, a non-for-profit organization that conducts research with pharmaceutical companies such as the study’s sponsor.

Only 1.5% of individuals at high risk of opioid overdose receive naloxone
The vast majority of individuals at high risk for opioid overdose do not receive naloxone, despite numerous opportunities, according to Sarah Follman and associates from the University of Chicago.
In a retrospective study published in JAMA Network Open, the study authors analyzed data from individuals in the Truven Health MarketScan Research Database who had ICD-10 codes related to opioid use, misuse, dependence, and overdose. Data from Oct. 1, 2015, through Dec. 31, 2016, were included; a total of 138,108 high-risk individuals were identified as interacting with the health care system nearly 1.2 million times (88,618 hospitalizations, 229,680 ED visits, 298,058 internal medicine visits, and 568,448 family practice visits).
Of the 138,108 individuals in the study, only 2,135 (1.5%) were prescribed naloxone during the study period. Patients who had prior diagnoses of both opioid misuse/dependence and overdose were significantly more likely to receive naloxone than were those who only had a history of opioid dependence (odds ratio, 2.32; 95% confidence interval, 1.98-2.72; P less than .001). In addition, having a history of overdose alone was associated with a decreased chance of receiving naloxone, compared with those with a history of opioid misuse alone (OR, 0.73; 95% CI, 0.57-0.94; P = .01).
Other factors that significantly reduced the odds of receiving naloxone included being aged 30-44 years and being from the Midwest or West. Factors that reduced the odds include having received treatment for opioid use disorder, visiting a detoxification facility, receiving other substance use disorder treatment; and having received outpatient care from a pain specialist, psychologist, or surgeon.
“Most individuals at high risk of opioid overdose do not receive naloxone through direct prescribing,” Ms. Follman and associates wrote. “Clinicians can address this gap by regularly prescribing naloxone to eligible patients. To address barriers to prescribing, hospital systems and medical schools can support clinicians by improving education on screening and treating substance use disorders, clarifying legal concerns, and developing policies and protocols to guide implementation of increased prescribing.
No conflicts of interest were reported; one coauthor reported receiving a grant from the National Institutes of Health.

Opioid management program reduced number of narcotics prescribed after breast surgery
An opioid prescription management program implemented at the Cleveland Clinic has led to a reduction in the number of narcotics prescribed to patients after breast surgery, according to research presented in a recent webcast from the annual meeting of the American Society of Breast Surgeons.
“The opioid epidemic has become a critical issue, and narcotic abuse has continued to rise,” Stephanie Valente, DO, FACS, from the Cleveland Clinic, said in her presentation. “Excess narcotic prescriptions may be contributing to this opioid epidemic,” and there are no current narcotic prescribing guidelines for patients after breast surgery, she said. In addition, studies have shown surgeons can overestimate the number of opioid pills a patient needs after surgery for pain control, and any excess pills are at risk of being stolen or inappropriately used, she added.
Dr. Valente and colleagues performed a baseline evaluation of narcotic pills prescribed by surgeons at the Cleveland Clinic for patients who have undergone excisional biopsy or lumpectomy, mastectomy, and mastectomy with reconstruction. They found the median number of narcotics prescribed were 15 pills for excisional biopsy or lumpectomy patients, 20 pills for mastectomy patients and 28 pills for mastectomy with reconstruction patients.
The researchers sought to lower those numbers, and created a departmental change in which they decreased the median number of pills prescribed at discharge from 15 pills to 10 pills for excisional biopsy or lumpectomy patients and from 28 pills to 25 pills for patients who undergo mastectomy with reconstruction. They then examined 100 consecutive patients after a 3-month implementation period to determine whether prescribing numbers had changed and found the surgeons adhered to the prescribing guidelines, which resulted in a statistically significant reduction in median opioid pills prescribed for excisional biopsy or lumpectomy (P less than .01) and mastectomy with reconstruction patients (P less than .01).
“After their departmental plan change, we observed that, as planned, a statistically significant decrease in prescribing practices amongst surgeons was able to be performed, showing that surgeons were able to adhere to these new prescribing practices,” said Dr. Valente.
When they examined the number of pills patients reported they used after surgery, they found excisional biopsy or lumpectomy patients took an average of 1 pill, mastectomy patients took an average of 3 pills, and mastectomy with reconstruction patients took an average of 18 pills. “These were all statistically much less than what was being prescribed even after our purposeful reduction,” said Dr. Valente.
In the study, 40% of patients who underwent breast surgery overall reported that they did not have any postoperative narcotic use at all, with the least narcotic use seen among patients who underwent excisional biopsy or lumpectomy.
“Further directions for opiate reduction can include evaluation of the impact of type and amount of local anesthetic given intraoperatively, and the amount of narcotics used postoperatively … to identify patient factors that contribute to the low narcotic usage postoperatively, and finally, to figure out how to maximize the benefit of adding a formal ERAS [enhanced recovery after surgery] protocol to further reduce patient needs for as many narcotic pills,” said Dr. Valente.
Dr. Valente had no disclosures.
An opioid prescription management program implemented at the Cleveland Clinic has led to a reduction in the number of narcotics prescribed to patients after breast surgery, according to research presented in a recent webcast from the annual meeting of the American Society of Breast Surgeons.
“The opioid epidemic has become a critical issue, and narcotic abuse has continued to rise,” Stephanie Valente, DO, FACS, from the Cleveland Clinic, said in her presentation. “Excess narcotic prescriptions may be contributing to this opioid epidemic,” and there are no current narcotic prescribing guidelines for patients after breast surgery, she said. In addition, studies have shown surgeons can overestimate the number of opioid pills a patient needs after surgery for pain control, and any excess pills are at risk of being stolen or inappropriately used, she added.
Dr. Valente and colleagues performed a baseline evaluation of narcotic pills prescribed by surgeons at the Cleveland Clinic for patients who have undergone excisional biopsy or lumpectomy, mastectomy, and mastectomy with reconstruction. They found the median number of narcotics prescribed were 15 pills for excisional biopsy or lumpectomy patients, 20 pills for mastectomy patients and 28 pills for mastectomy with reconstruction patients.
The researchers sought to lower those numbers, and created a departmental change in which they decreased the median number of pills prescribed at discharge from 15 pills to 10 pills for excisional biopsy or lumpectomy patients and from 28 pills to 25 pills for patients who undergo mastectomy with reconstruction. They then examined 100 consecutive patients after a 3-month implementation period to determine whether prescribing numbers had changed and found the surgeons adhered to the prescribing guidelines, which resulted in a statistically significant reduction in median opioid pills prescribed for excisional biopsy or lumpectomy (P less than .01) and mastectomy with reconstruction patients (P less than .01).
“After their departmental plan change, we observed that, as planned, a statistically significant decrease in prescribing practices amongst surgeons was able to be performed, showing that surgeons were able to adhere to these new prescribing practices,” said Dr. Valente.

Outpatient program successfully tackles substance use and chronic pain
MILWAUKEE – An interdisciplinary intensive outpatient treatment program addressing chronic pain and substance use disorder effectively addressed both diagnoses in a military population.
Intensive outpatient programs (IOPs) frequently address these conditions within a biopsychosocial format, but it’s not common for IOPs to have this dual focus on chronic pain and substance use disorder (SUD), said Michael Stockin, MD, speaking in an interview at the scientific meeting of the American Pain Society.
Dr. Stockin said he and his collaborators recognized that, especially among a military population, the two conditions have considerable overlap, so it made sense to integrate behavioral treatment for both conditions in an intensive outpatient program. “Our hypothesis was that if you can use an intensive outpatient program to address substance use disorder, maybe you can actually add a chronic pain curriculum – like a functional restoration program to it.
“As a result of our study, we did find that there were significant differences in worst pain scores as a result of the program. In the people who took both the substance use disorder and chronic pain curriculum, we found significant reductions in total impairment, worst pain, and they also had less … substance use as well,” said Dr. Stockin.
In a quality improvement project, Dr. Stockin and collaborators compared short-term outcomes for patients who received IOP treatment addressing both chronic pain and SUD with those receiving SUD-only IOP.
For those participating in the joint IOP, scores indicating worst pain on the 0-10 numeric rating scale were reduced significantly, from 7.55 to 6.23 (P = .013). Scores on a functional measure of impairment, the Pain Outcomes Questionnaire Short Form (POQ-SF) also dropped significantly, from 84.92 to 63.50 (P = .034). The vitality domain of the POQ-SF also showed that patients had less impairment after participation in the joint IOP, with scores in that domain dropping from 20.17 to 17.25 (P = .024).
Looking at the total cohort, patient scores on the Brief Addiction Monitor (BAM) dropped significantly from baseline to the end of the intervention, indicating reduced substance use (P = .041). Mean scores for participants in the joint IOP were higher at baseline than for those in the SUD-only IOP (1.000 vs. 0.565). However, those participating in the joint IOP had lower mean postintervention BAM scores than the SUD-only cohort (0.071 vs. 0.174).
American veterans experience more severe pain and have a higher prevalence of chronic pain than nonveterans. Similarly, wrote Dr. Stockin, a chronic pain fellow in pain management at Walter Reed National Military Medical Center, Bethesda, Md., and colleagues in the poster presentation.
The project enrolled a total of 66 patients (10 female and 56 male). Of these, 18 participated in the joint SUD–chronic pain program, and 48 received usual treatment of the SUD-only IOP treatment. The mean overall age was 33.2 years, and 71.2% of participants were white.
Overall, 51 patients (77.3%) of participants had alcohol use disorder. Participants included active duty service members, veterans, and their dependents. Opioid and cannabis use disorders were experienced by a total of eight patients, and seven more patients had diagnoses of alcohol use disorder along with other substance use disorders.
All patients completed the BAM and received urine toxicology and alcohol breath testing at enrollment; drug and alcohol screening was completed at other points during the IOP treatment for both groups as well.
The joint IOP ran 3 full days a week, with a substance use curriculum in the morning and a pain management program in the afternoon; the SUD-only participants had three morning sessions weekly. Both interventions lasted 6 weeks, and Dr. Stockin said he and his colleagues would like to acquire longitudinal data to assess the durability of gains seen from the joint IOP.
The multidisciplinary team running the joint IOP was made up of an addiction/pain medicine physician, a clinical health psychologist, a physical therapist, social workers, and a nurse.
“This project is the first of its kind to find a significant reduction in pain burden while concurrently treating addiction and pain in an outpatient military health care setting,” Dr. Stockin and colleagues wrote in the poster accompanying the presentation.
“We had outcomes in both substance use and chronic pain that were positive, so it suggests that in the military health system, people may actually benefit from treating both chronic pain and substance use disorder concurrently. If you could harmonize those programs, you might be able to get good outcomes for soldiers and their families,” Dr. Stockin said.
Dr. Stockin reported no conflicts of interest. The project was funded by the Defense Health Agency.

Medical cannabis relieved pain, decreased opioid use in elderly
results of a recent retrospective chart review suggest. Treatment with medical cannabis improved pain, sleep, anxiety, and neuropathy in patients aged 75 years of age and older, and was associated with reduced use of opioids in about one-third of cases, according to authors of the study, which will be presented at the annual meeting of the American Academy of Neurology.
“Our findings are promising and can help fuel further research into medical marijuana as an additional option for this group of people who often have chronic conditions,” said lead investigator Laszlo Mechtler, MD, of Dent Neurologic Institute in Buffalo, N.Y., in a news release. However, additional randomized, placebo-controlled studies are needed to confirm results of this study, Dr. Mechtler added.
The chart review focused on 204 elderly patients who participated in New York State’s medical marijuana program and were followed in a neurologic outpatient setting. The cohort included 129 female and 75 male patients, ranging in age from 75 to 102 years, with a mean age of 81 years. The medical marijuana was taken by mouth as a liquid extract tincture, capsule, or in an electronic vaporizer.
With an average exposure time of 16.8 weeks, 69% of patients experienced symptomatic benefit, according to patient self-report. The most commonly reported benefit was relief of chronic pain in 49%, while improvements in sleep, neuropathy, and anxiety were reported in 18%, 15%, and 10%, respectively. Reductions in opioid pain medication were noted in about one-third of cases, they found.
While 34% of patients had adverse effects on medical marijuana, only 21% reported adverse effects after cannabinoid doses were adjusted, investigators said. Adverse effects led to discontinuation of medical cannabis in seven patients, or 3.4% of the overall cohort. Somnolence, disequilibrium, and gastrointestinal disturbance were the most common adverse effects, occurring in 13%, 7%, and 7% of patients, respectively. Euphoria was reported in 3% of patients.
Among patients who had no reported adverse effects, the most commonly used formulation was a balanced 1:1 tincture of tetrahydrocannabinol to cannabidiol, investigators said.
Further trials could explore optimal dosing of medical cannabis in elderly patients and shed more light on adverse effects such as somnolence and disequilibrium, according to Dr. Mechtler and colleagues.
The study was supported by the Dent Family Foundation.
