Pain

Sexual assault in the military is more likely to cause lasting sexual pain in female veterans than a history of childhood sexual abuse, according to an observational study involving interviews with more than 1,000 military women.

Female veterans with histories of both childhood sexual abuse and sexual assault in the military were 4.33 times more likely to report sexual pain than female veterans with no history of sexual assault; women whose history of sexual assault occurred in the military only were 2.37 times more likely to report sexual pain. Those with histories of childhood sexual abuse but no military assaults were 1.75 times more likely to report sexual pain than those who had no history of sexual assault.

The findings suggest that sexual assault in the military is more detrimental to sexual function than childhood sexual abuse alone, which “is distinct from the pattern long observed in civilian women that childhood sexual abuse confers a greater risk for sexual pain than adulthood sexual assault,” Carey S. Pulverman, PhD, then of the Department of Veterans Affairs Center of Excellence for Research on Returning War Veterans in Waco, Tex., and coinvestigators wrote in Obstetrics & Gynecology.

The findings come from a secondary analysis of data collected for a larger project titled Sexual Violence and Women Veterans’ Gynecologic Health . The research team conducted telephone interviews with 1,004 female veterans younger than 52 years of age (mean, 38 years) who were enrolled at two large Midwestern VA medical centers and associated clinics. Sexual pain was assessed by one question: “Does it hurt you to have sexual intercourse or penetration?”

The study also identified high comorbidity between sexual pain and mental health concerns. As with sexual pain, rates of depression and PTSD were highest among female veterans with histories of both sexual abuse in childhood and sexual assault in the military, followed by women with histories of sexual assaults in the military alone, and then women with histories of childhood sexual abuse alone. Women with both histories were 6.35 times more likely to report PTSD, and 3.91 times more likely to report depression, compared with female veterans with no history of sexual assault.

Women who experienced sexual assault during their childhood and/or while serving in the military also may have been exposed to sexual assault during their pre- or postmilitary adulthood as well, but this was a small number and its effects were not evaluated, the authors noted.

Especially given the “growing numbers of women serving in the military and prevalence of sexual assault in this population,” there’s a need for more research on the sexual function of female veterans and development of “targeted treatments,” the investigators wrote.

For now, providers should be “more comprehensive in their assessment of sexual assault history” and should consider developing relationships with community providers who specialize in sexual health, they added.

The study was funded by the VA. The authors did not report any relevant financial disclosures.

Contrary to previous research indicating that medical cannabis laws reduced opioid overdose mortality, the association between these two has reversed, with opioid overdose mortality increased in states with comprehensive medical cannabis laws, according to Chelsea L. Shover, PhD, and associates.

The original research by Marcus A. Bachhuber, MD, and associates showed that the introduction of state medical cannabis laws was associated with a 24.8% reduction in opioid overdose deaths per 100,000 population between 1999 and 2010. In contrast, the new research – which looked at a longer time period than the original research did – found that the association between state medical cannabis laws and opioid overdose mortality reversed direction, from ­–21% to +23%.

“We find it unlikely that medical cannabis – used by about 2.5% of the U.S. population – has exerted large conflicting effects on opioid overdose mortality,” wrote Dr. Shover, of the department of psychiatry and behavioral sciences at Stanford (Calif.) University, and associates. “A more plausible interpretation is that this association is spurious.” Their study was published in the Proceedings of the National Academy of Sciences.

To conduct their analysis, Dr. Shover and associates extended the timeline reviewed by Dr. Bachhuber and associates to 2017. During 2010-2017, 32 states enacted medical cannabis laws, including 17 allowing only medical cannabis with low levels of tetrahydrocannabinol (THC), and 8 legalized recreational marijuana. In the expanded timeline during 1999-2017, states possessing a comprehensive medical marijuana law saw an increase in opioid overdose mortality of 28.2%. Meanwhile, states with recreational marijuana laws saw a decrease of 14.7% in opioid overdose mortality, and states with low-THC medical cannabis laws saw a decrease of 7.1%. However, the investigators noted that those values had wide confidence intervals, which indicates “compatibility with large range of true associations.”

“The nonrobustness of the earlier findings also highlights the challenges of controlling scientific messages in controversial policy areas. Corporate actors with deep pockets have substantial ability to promote congenial results, and suffering people are desperate for effective solutions. Cannabinoids have demonstrated therapeutic benefits, but reducing population-level opioid overdose mortality does not appear to be among them,” Dr. Shover and associates noted.

SAN ANTONIO – Episodic migraine patients benefit from mindfulness-based stress reduction training, according to new research. The intervention reduced headache frequency, slightly increased whole-brain gray matter volume, and reduced symptoms of anxiety, depression, and stress.

stockdevil/Thinkstock

The gray matter findings may indicate opportunities for therapeutic targets, while the psychosocial findings are important in understanding migraine burden, treatment response, and personalized medicine opportunities, Shana Burrowes, PhD, a postdoctoral associate at Boston University, said at the annual meeting of the College on Problems of Drug Dependence.

In a session focused on exploring alternatives to opioids for pain treatment, Dr. Burrowes described interim results of a randomized, controlled trial testing the effectiveness of mindfulness-based stress reduction (MBSR) training for managing migraine.

In discussing the rationale for study endpoints, she explained a three-pronged model for understanding migraine. Those elements include the symptoms themselves – unilateral throbbing pain, nausea, and photophobia – and the psychosocial symptoms and comorbidities, including anxiety, depression, stress, and catastrophizing. Up to 30%* of migraine patients have comorbid depression.

Those two prongs have a bidirectional relationship, since each increases the risk of the other. For example, frequent migraine can leave people feeling anxious about when their next migraine will occur, and that anxiety can increase the risk of it occurring.

Both elements lead to the third prong, which is change in gray matter volume. “If you’re a patient with migraine, an MRI on your brain is going to look different from somebody who does not have migraine,” Dr. Burrowes said. “With all these things going on in a patient, a migraine patient is actually pretty difficult to treat.”

Therefore, the researchers focused on outcomes from each of these three domains: gray matter volume in MRI; headache frequency as a clinical outcome; and the psychosocial comorbidities of anxiety, stress, and depression.

Study participants included 98 patients with episodic migraine, defined as fewer than 15 headache days a month, and 27 controls* matched by demographics to the patients and without any chronic pain conditions. The groups were 92% female and had similar ratios of whites (75% and 77%) and college graduates (95% and 96%).

Only the patients were randomized to the two interventions, one a training on MBSR and the other focusing on stress management for headache (SMH).

The MBSR training involved group sessions, eight 2.5-hour meditation sessions, at-home practice, a half-day retreat, and then an additional four biweekly sessions. The mindfulness training specifically focused on intentionally paying attention in the moment without judgment. The SMH arm focused on education for managing headache symptoms, stress, sleep hygiene, and diet, but it did not involve any specific skills training, such as relaxation training.

All participants, including healthy controls, underwent clinical assessment and baseline MRI and psychosocial questionnaires, followed by MRI and psychosocial questionnaire follow-ups at 3 and 6 months. MRI imaging focused on the whole brain and on the bilateral insula, dorsolateral prefrontal cortex, anterior cingulate cortex, and superior frontal gyrus. Patients also kept headache diaries throughout the trial.

Both intervention groups showed an increase in gray matter volume over 6 months, compared with healthy controls: 1.3% in the whole brain for SMH participants and 1.01% in the MBSR patients, compared with –1.37% in healthy participants. In the right superior frontal gyrus, gray matter volume also increased 2.62% in SMH participants and 1.25% in MBSR patients but decreased 0.19% in healthy participants.

Dr. Burrowes said she could not share specific findings on headache frequency and psychosocial outcomes because her team’s research is currently under review. Overall, however, headache frequency declined more than 50% post intervention, and 39% of migraine patients responded to the therapy.

In addition, anxiety, stress, and depression symptoms all saw improvements from MBSR and slightly but significantly mediated the effect of MBSR on migraine reduction.

Dr. Burrowes reported having no disclosures.

ANSWER

The radiograph shows no evidence of an acute fracture. Incidental findings include excreted contrast within the bladder and radiopaque markers from prostatic seed implants.

Fairly extensive sclerosis is noted within both femoral heads, which is suggestive of osteonecrosis (also known as avascular necrosis). Orthopedic consult was requested for further workup of this specific problem.

Young patients might be at increased risk of suicidal behavior, unintentional overdose, injuries, and traffic incidents during treatment periods with gabapentinoids, compared with periods without treatment with those medications, a cohort study of almost 200,000 people shows. Pregabalin is associated with higher hazards of those outcomes than is gabapentin, and the associations are strongest in patients aged 15-24 years, the researchers reported.

“If our findings are triangulated with other forms of evidence, clinical guidelines may need review regarding prescriptions for young people and those with substance use disorders,” wrote Yasmina Molero, PhD, and associates. “Further restrictions for off-label prescription may need consideration.” The study was published in BMJ.

The use of gabapentinoids has risen in the United States (JAMA Intern Med. 2018;178[2]:292-4), and overdose deaths tied to gabapentin have led some states to explore reclassification of the drug as a controlled substance (Risk Manag Healthc Policy. 2018;11:109-16). In the United Kingdom, gabapentinoids are being reclassified as a class C controlled drug because of concerns about the risk of addiction, overdose, and safety, wrote Dr. Molero of the department of psychiatry at Warneford Hospital at the University of Oxford, England, and associates.

To study associations between gabapentinoids and adverse outcomes related to coordination, mental health, and criminality, Dr. Molero and her associates analyzed data from 191,973 people from the Swedish Prescribed Drug Register who collected prescriptions for pregabalin or gabapentin between 2006 and 2013. The researchers included patients aged 15 years and older in their analyses.

They examined suicidal behavior, unintentional overdoses, head or body injuries, road traffic incidents and offenses, and arrests for violent crime using the Swedish Patient Register and the National Crime Register. In addition, they defined suicidal behavior as emergency hospital visits attributable to self-injurious behavior or suicide attempt, or death by suicide. Unintentional overdoses were defined as emergency hospital visits or death attributable to poisoning by illicit drugs, medications, or biologic substances; accidental poisoning by noxious substances; or acute intoxications and overdoses by alcohol and illicit drugs, excluding intentional self-poisoning, wrote Dr. Molero, who is affiliated with the Karolinska Institute in Stockholm, and her associates.

Of the nearly 192,000 participants who collected prescriptions of gabapentinoids on at least two consecutive occasions, 120,664 received pregabalin, and 85,360 received gabapentin; 14,051 of the participants received both drugs. Fifty-nine percent were women, and most patients were aged 45 or older.

During the study period, 10,026 participants (5.2%) were treated for suicidal behavior or died from suicide, 17,144 participants (8.9%) experienced an unintentional overdose, and 12,070 participants (6.3%) had a road traffic incident or offense. In addition, 70,522 participants (36.7%) had head or body injuries, and 7,984 participants (4.1%) were arrested for a violent crime.

Of the nearly 192,000 participants who collected prescriptions of gabapentinoids on at least two consecutive occasions, 120,664 received pregabalin, and 85,360 received gabapentin; 14,051 of the participants received both drugs. Fifty-nine percent were women, and most patients were aged 45 or older.

During the study period, 10,026 participants (5.2%) were treated for suicidal behavior or died from suicide, 17,144 participants (8.9%) experienced an unintentional overdose, and 12,070 participants (6.3%) had a road traffic incident or offense. In addition, 70,522 participants (36.7%) had head or body injuries, and 7,984 participants (4.1%) were arrested for a violent crime.

Young patients might be at increased risk of suicidal behavior, unintentional overdose, injuries, and traffic incidents during treatment periods with gabapentinoids, compared with periods without treatment with those medications, a cohort study of almost 200,000 people shows. Pregabalin is associated with higher hazards of those outcomes than is gabapentin, and the associations are strongest in patients aged 15-24 years, the researchers reported.

“If our findings are triangulated with other forms of evidence, clinical guidelines may need review regarding prescriptions for young people and those with substance use disorders,” wrote Yasmina Molero, PhD, and associates. “Further restrictions for off-label prescription may need consideration.” The study was published in BMJ.

The use of gabapentinoids has risen in the United States (JAMA Intern Med. 2018;178[2]:292-4), and overdose deaths tied to gabapentin have led some states to explore reclassification of the drug as a controlled substance (Risk Manag Healthc Policy. 2018;11:109-16). In the United Kingdom, gabapentinoids are being reclassified as a class C controlled drug because of concerns about the risk of addiction, overdose, and safety, wrote Dr. Molero of the department of psychiatry at Warneford Hospital at the University of Oxford, England, and associates.

To study associations between gabapentinoids and adverse outcomes related to coordination, mental health, and criminality, Dr. Molero and her associates analyzed data from 191,973 people from the Swedish Prescribed Drug Register who collected prescriptions for pregabalin or gabapentin between 2006 and 2013. The researchers included patients aged 15 years and older in their analyses.

They examined suicidal behavior, unintentional overdoses, head or body injuries, road traffic incidents and offenses, and arrests for violent crime using the Swedish Patient Register and the National Crime Register. In addition, they defined suicidal behavior as emergency hospital visits attributable to self-injurious behavior or suicide attempt, or death by suicide. Unintentional overdoses were defined as emergency hospital visits or death attributable to poisoning by illicit drugs, medications, or biologic substances; accidental poisoning by noxious substances; or acute intoxications and overdoses by alcohol and illicit drugs, excluding intentional self-poisoning, wrote Dr. Molero, who is affiliated with the Karolinska Institute in Stockholm, and her associates.

SAN FRANCISCO – Up to 21% of psychiatry residency programs provide no training or supervision for managing and treating chronic pain, and pain-related training and supervision by remaining programs is minimal, a new national survey shows.

Given the unique role of psychiatrists in helping chronic pain patients with coping strategies and managing comorbid psychiatric illness, this void is concerning, said Ali Ahsan Ali, MD, a resident psychiatrist at the Micah School of Medicine at Mount Sinai/Elmhurst Hospital Center in New York, in an interview at the annual meeting of the American Psychiatric Association.

In a video interview, Dr. Ali spoke with Ahmar M. Butt, MD, about how and why Dr. Ali and his colleagues conducted the survey of all 221 U.S. psychiatry residency programs in January 2019. They also discuss the implications of these trends for patients, particularly in light of the country’s opioid crisis.

Dr. Ali had no disclosures. Dr. Butt is board certified in general psychiatry, child and adolescent psychiatry, and preventive medicine, with a subspecialty in addiction medicine.

Pediatric herpes zoster declined by 72% in the years following introduction of routine varicella vaccination, with the rates in vaccinated children 78% lower than those in unvaccinated children.

KatarzynaBialasiewicz/Thinkstock

The benefit became largely apparent after children received the second vaccination in the recommended series, and persisted throughout childhood, Sheila Weinmann, PhD, of Kaiser Permanente Northern California, Oakland, and colleagues said.*

The analysis included 6.37 million children in the Kaiser Permanente database, 50% of whom were vaccinated for all or some of the study period stretching from 2003 to 2014. Overall, the crude lab-confirmed herpes zoster (HZ) incidence rate was 74/100,000 person-years. When stratified by vaccine status, the crude rate of HZ among vaccinated children was 78% lower than among unvaccinated children (38 vs. 170 cases per 100,000 person years).

Herpes zoster was more common among girls than boys and up to six times more common in immunosuppressed children than in nonimmunosuppressed children.

The authors also found that unvaccinated children benefited from the high rate of vaccination around them. Although the HZ rate was always lower among vaccinated children, the rate among unvaccinated children fell sharply after 2007.

“The trend of decreasing HZ incidence among children who were unvaccinated is likely due to a lack of primary VZV [varicella-zoster virus] infection resulting from herd immunity in a highly vaccinated population,” Dr. Weinmann and her associates said.

There was some variability among age groups, especially among the youngest who were not fully vaccinated.

“In the group aged 1-2 years, the confirmation-adjusted HZ rate among children who were vaccinated was 70% higher than among those who were unvaccinated,” the authors said. In the “older groups, HZ rates were significantly higher in children who were unvaccinated than in those who were vaccinated,” the researchers noted.

The highest incidence was among vaccinated 1-year-olds, who had a 140% higher risk of HZ than did unvaccinated 1-year-olds. But this risk elevation disappeared by age 2 years. For everyone else, aged 2-17 years, the rate of HZ remained significantly lower in vaccinated children.

“Among the small number of children vaccinated at 11 months of age (for whom the vaccine is not recommended), the HZ incidence rate was significantly higher than in children vaccinated at 1 year of age and older. Similarly, children who contract wild-type varicella infection at younger than 1 year of age also have a higher risk of HZ (relative risk, 13.5). The immature adaptive T-cell response in children less than 1 year of age appears less able to contain VZV as a latent infection, compared with older children.

“Our findings for 11-month-olds who were vaccinated should be interpreted with caution because this population included only three cases of HZ and could have included children participating in a prelicensure study with a vaccine formulation different from Varivax,” Dr. Weinmann and her associates said.

Dr. Weinmann and her associates reported no relevant financial disclosures. The study was supported by the Centers for Disease Control and Prevention.

A 46-year-old man with no significant medical history presents to the emergency department (ED) with right flank pain and nausea. CT reveals a 5-mm ureteral stone with no obstruction or hydronephrosis. You are planning to start him on IV ketorolac for pain. What is the most appropriate dose?

Ketorolac tromethamine is a highly effective NSAID. As a nonopiate analgesic, it is often the first choice for the treatment of acute pain in the flank, abdomen, musculoskeletal system, or head.² While it is not associated with euphoria, withdrawal effects, or respiratory depression (like its opiate analgesic counterparts), ketorolac carries an FDA black-box warning for gastrointestinal, cardiovascular, renal, and bleeding risks.³

NSAIDs are known to have a “ceiling dose” at which maximum analgesic benefit is achieved; higher doses will not provide further pain relief. Higher doses of ketorolac may be used when the anti-inflammatory effects of NSAIDs are desired, but they are likely to cause more adverse effects.⁴ Available data describe the ceiling dose of ketorolac as 10 mg across dosage forms—yet the majority of research and most health care providers in current practice use higher doses (20 to 60 mg).^4,5 The FDA-approved labeling provides for a maximum dose of 60 mg/d.³

In one recent study, ketorolac was prescribed above its ceiling dose in at least 97% of patients who received IV doses and at least 96% of those who received intramuscular (IM) doses in a US ED.⁶ If 10 mg of ketorolac is an effective analgesic dose, current practice exceeds the label recommendation to use the lowest effective dose. This study sought to determine the comparative efficacy of 3 different doses of IV ketorolac for acute pain management in an ED.

STUDY SUMMARY

10 mg of ketorolac is enough for pain

This randomized double-blind trial evaluated the effectiveness of ketorolac in 240 adult patients (ages 18 to 65) presenting to an ED with acute flank, abdominal, musculoskeletal, or headache pain.¹ Acute pain was defined as onset within the past 30 days.

Patients were randomly assigned to receive either 10, 15, or 30 mg of IV ketorolac in 10 mL of normal saline. A pharmacist prepared the medication in identical syringes, which were delivered in a blinded manner to the nurses caring for the patients. Pain (measured using a 0-to-10 scale), vital signs, and adverse effects were assessed at baseline and at 15, 30, 60, 90, and 120 minutes. If patients were still in pain at 30 minutes, IV morphine (0.1 mg/kg) was offered. The primary outcome was a numerical pain score at 30 minutes after ketorolac administration; secondary outcomes included the occurrence of adverse events and the use of rescue medication (morphine).

The treatment groups were similar in terms of demographics and baseline vital signs. Mean age was 39 to 42. Across the 3 groups, 36% to 40% of patients had abdominal pain, 26% to 39% had flank pain, 20% to 26% had musculoskeletal pain, and 1% to 11% had headache pain. Patients had experienced pain for an average of 1.5 to 3.5 days.

Continue to: Baseline pain scores...

Baseline pain scores were similar for all 3 groups (7.5-7.8 on a 10-point scale). In the intention-to-treat analysis, all 3 doses of ketorolac decreased pain significantly at 30 minutes, with no difference between the groups: mean pain scores postintervention were 5.1 for the 10- and 15-mg group and 4.8 for the 30-mg group. There was no difference between the groups at any other time intervals. There was also no difference between groups in the number of patients who needed rescue medication at 30 minutes (4 patients in the 10-mg group, 3 patients in the 15-mg group, and 4 patients in the 30-mg group). In addition, adverse events (eg, dizziness, nausea, headache, itching, flushing) did not differ between the groups.

WHAT’S NEW

10 mg is just as effective as 30 mg

This trial confirms that a low dose of IV ketorolac is just as effective as higher doses for acute pain control.

CAVEATS

2-hour limit; no look at long-term effects

It isn’t known whether the higher dose would have provided greater pain relief beyond the 120 minutes evaluated in this trial, or if alternative dosage forms (oral or IM) would result in different outcomes. This study was not designed to compare serious long-term adverse effects such as bleeding, renal impairment, or cardiovascular events. Additionally, this study was not powered to look at specific therapeutic indications or anti-inflammatory response.

CHALLENGES TO IMPLEMENTATION

10-mg single-dose vial not readily available

Ketorolac tromethamine for injection is available in the United States in 15-, 30-, and 60-mg single-dose vials. Because a 10-mg dose is not available as a single-dose vial, it would need to be specially prepared (as it was in this study). However, this study should reassure providers that using the lowest available dose (eg, 15 mg IV if that is what is available) will relieve acute pain as well as higher doses will. CR

This trial confirms that a low dose of IV ketorolac is just as effective as higher doses for acute pain control.

CAVEATS

2-hour limit; no look at long-term effects

It isn’t known whether the higher dose would have provided greater pain relief beyond the 120 minutes evaluated in this trial, or if alternative dosage forms (oral or IM) would result in different outcomes. This study was not designed to compare serious long-term adverse effects such as bleeding, renal impairment, or cardiovascular events. Additionally, this study was not powered to look at specific therapeutic indications or anti-inflammatory response.

CHALLENGES TO IMPLEMENTATION

10-mg single-dose vial not readily available

Ketorolac tromethamine for injection is available in the United States in 15-, 30-, and 60-mg single-dose vials. Because a 10-mg dose is not available as a single-dose vial, it would need to be specially prepared (as it was in this study). However, this study should reassure providers that using the lowest available dose (eg, 15 mg IV if that is what is available) will relieve acute pain as well as higher doses will. CR

Fewer opioid retail prescriptions are being filled, according to a new report issued by the American Medical Association Opioid Task Force.

Opioid prescribing declined by 33% over a 5-year period based on the total number of opioid retail prescriptions filled. Total prescriptions declined from 251.8 million in 2013 to 168.8 million in 2018, according to the report.

The numbers come as the most recent data from the Centers for Disease Control and Prevention show a leveling of deaths involving prescription opioids. The CDC data were most recently updated in January 2019 and cover the period 1999-2017.

A closer look shows that deaths involving prescription opioids, but not other synthetic narcotics, peaked in 2011 and have generally declined since then. Deaths involving other synthetic narcotics, however, have been rising, offsetting the reduction and keeping the total number of deaths involving opioids relatively stable between 2016 and 2017.

Other data released by the AMA Opioid Task Force show that physicians are increasing their use of state-level prescription drug monitoring programs (PDMPs).

In 2017, there were 1.5 million physicians registered to use state PDMPs. That number rose to 1.97 million in 2019. And the physicians are using PDMPs. In 2018, physicians made 460 million PDMP queries, up 56% from 2017 and up 651% from 2014.

More education about opioid prescribing is being sought, with 700,000 physicians completing CME training and accessing other training related to opioid prescribing, pain management, screening for substance use disorders, and other related topics.

While the report does show positive trends, the task force is calling for more action, including more access to naloxone and better access to mental health treatment.

The report notes that more than 66,000 physicians and other health professionals have a federal waiver to prescribe buprenorphine, up more than 28,000 since 2016.

A number of policy recommendations are made in the report, including removing inappropriate administrative burdens or barriers that delay access to medications used in medication-assisted treatment (MAT); removing barriers to comprehensive pain care and rehabilitation programs, and reforming the civil and criminal justice system to help ensure access to high-quality, evidence-based care for opioid use disorder.

“We are at a crossroads in our nation’s efforts to end the opioid epidemic,” AMA Opioid Task Force Chair Patrice A. Harris, MD, stated in the report. “It is time to end delays and barriers to medication-assisted treatment – evidence based care proven to save lives; time for payers, [pharmacy benefit managers] and pharmacy chains to reevaluate and revise policies that restrict opioid therapy to patients based on arbitrary thresholds; and time to commit to helping all patients access evidence-based care for pain and substance use disorders.”

Dr. Harris continued: “Physicians must continue to demonstrate leadership, but unless these actions occur, the progress we are making will not stop patients from dying.”

TORONTO – A high level of pain catastrophizing prior to scheduled knee arthroplasty is not, as previously thought, a harbinger of poor outcomes, and affected patients don’t benefit from cognitive-behavioral therapy–based training in pain coping skills, Daniel L. Riddle, PhD, reported at the OARSI 2019 World Congress.

“The take-home message for us is knee arthroplasty is incredibly effective and there really is no reason to do pain coping skills training in these high–pain catastrophizing patients because the great majority of them have such good outcomes,” said Dr. Riddle, professor of physical therapy at Virginia Commonwealth University, Richmond.

“The other clear message from our trial is that, when you have pain-catastrophizing patients and you lower their pain, their catastrophizing is also lowered. So pain catastrophizing is clearly a response to pain and not a personality trait per se,” he said at the meeting sponsored by the Osteoarthritis Research Society International.

He presented the results of a 402-patient, randomized, three-arm, single-blind trial conducted at five U.S. medical centers. All participants were scheduled for knee arthroplasty for osteoarthritis, and all had moderate- to high-level pain catastrophizing as reflected in the group’s average Pain Catastrophizing Score of 30. They were assigned to an arthritis education active control group, usual care, or an intervention developed specifically for this study: a cognitive-behavioral therapy–based training program for pain coping skills. Similar pain coping skills training interventions have been shown to be beneficial in patients with medically treated knee OA but hadn’t previously been evaluated in surgically treated patients. The primary study endpoint was change in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Scale at 2, 6, and 12 months after surgery.

The improvement in WOMAC pain in the three study arms was virtually superimposable, going from an average pain score of about 12 preoperatively to 2 postoperatively.

“This was a clear no-effect trial,” Dr. Riddle observed. “These are patients we thought to be at increased risk for poor outcome, but indeed they’re not.”

Pain Catastrophizing Scores improved from 30 preoperatively to roughly 7 at 1 year. “We’ve never seen pain catastrophizing improvements of this magnitude,” the researcher commented.

The study participants typically had a large number of chronically painful areas, but only minimal change in pain scores occurred except in the surgically treated knee.

Of note, even with the impressively large improvements in knee pain, function, and other secondary endpoints in the study group as a whole, roughly 20% of study participants experienced essentially no improvement in their function-limiting knee pain during the first year after arthroplasty. These nonresponders were spread equally across all three study arms. Further research will be needed to develop interventions to help this challenging patient subgroup.

The pain coping skills training consisted of 8 weekly sessions, each an hour long, which began prior to surgery and continued afterward. The intervention was delivered by physical therapists who had been trained by pain psychologists with expertise in cognitive-behavioral therapy. The intervention was delivered by telephone and in face-to-face sessions. The trainers were tracked over the course of the study to make sure that the structured intervention was delivered as planned.

Dr. Riddle reported having no financial conflicts regarding the National Institutes of Health-funded study, the full details of which have been published (J Bone Joint Surg Am. 2019 Feb 6;101[3]:218-227).
