Public health intervention helps stem tuberculosis transmission
SAN DIEGO – Using an on-site multi-disciplinary team to approach patients who are unwilling to receive tuberculosis treatment can improve patient cooperation, according to a case study presented ID Week 2017, an infectious disease meeting.
Such public health interventions may be able to improve disease control and interrupt the transmission cycle among patients who are not adhering to treatment, according to Aisha Haynie, MD, MPA.
“We started the patient on treatment and she actually decided to move into a motel,” said Dr. Haynie. “After that, she moved back into the family home and said she wasn’t having any contact [with residents], which we didn’t really believe.”
While the patient did reluctantly give Dr. Haynie and her team a list of five family members to test, the patient told Dr. Haynie that she and her team were not allowed into the patient’s home.
When the five members were tested, the new patients showed similar signs of reluctance and mistrust of the health system.
“The family members came to our clinic and two of them were TB positive,” recounted Dr. Haynie. “So they came back, but while they were sitting in the waiting room, they signed papers and they left.”
Despite continuous attempts to reach the family and address the growing concern from health professionals of the danger of TB transmission to other members of the family, patients continue not to adhere to procedures beyond pharmaceutical intervention.
In an attempt to directly contact the patient’s family, Dr. Haynie lead a team consisting of a local health authority physician, a TB nurse practitioner, a TB contact analyst, a nurse case manager, a county attorney, and an interpreter for unscheduled visits to family members individually.
“We had specific requests [including] keeping appointments, getting labs, and we added a deadline,” said Dr. Haynie, Chief of Disease Control and Medical Epidemiology for the Harris County Public Health & Environmental Services. “By the next Friday [we told them that] we were filing court papers with or without the information and we [would] be contacting child protective services as well.”
Following the intervention, the patient and her family adhered to testing procedures. This revealed an infant with active TB and 8 other family members with TB Infection. Isolation breaches were also discovered. Most importantly, the TB transmission cycle was interrupted, according to Dr. Haynie.
A key aspect of the team’s successful approach was to address cultural and economic barriers that hindered successful interaction with the family, TB misconceptions corrected in order for a trusting relationship to develop.
The investigators developed this intervention in Harris County, Tx, which at 4.3 million residents is the 3rd most populous U.S. county, and has reported a TB case rate of 7.6 cases per 100,000, which is approximately double that of the U.S. average, according to Dr. Haynie. Of those cases in Harris County, 73% are foreign-born, compared with the average rate of 59% in Texas.
Dr. Haynie and fellow investigators asserted part of the reason patients were so reluctant to receive treatment from the Harris County Public Health department was a combination of mistrust in the system and a number of false ideas patients have regarding TB, a sign of further educational tools being needed.
Since the first use of the intervention, Dr. Haynie and her team have implemented this approach with other non-adherent patients with relative success.
“This is something that we now do and we have not been back to court [to enforce compliance] since,” said Dr. Haynie.

ID Week 2017
Inappropriate C. diff. testing reduced with ‘Hard Stop’ protocol
SAN DIEGO – After other strategies to reduce inappropriate testing for Clostridium difficile infection did not provide adequate reductions in inappropriate orders, a “hard stop” protocol, which prevents testing if specific conditions are not met, reduced the rate of testing by 42% without any incidence of delayed diagnosis, according to data presented at ID Week 2017.
“Testing stewardship is really critical to minimize the frequency of false-positive [Clostridium difficile infection] cases, which of course lead to harm. They lead to inappropriate treatment, prolonged length of stay, and patient dissatisfaction,” reported Marci L. Drees, MD, Infection Prevention Officer and Hospital Epidemiologist, Christiana Care Health System, Newark, Del.
“Of course, we did, at the time, educate our clinicians about this new testing algorithm, explaining how it is so much more sensitive and that they need to be smarter about who they are testing. But as we saw the cases roll in, we noticed that many of the [colonization] cases were in patients with a history of recent laxative use,” Dr. Drees recounted.
This led initially to a “soft stop” protocol in which clinicians ordering C. difficile–infection testing received an alert if laxatives had been ordered within the previous 24 hours. The alert provided details about the laxatives and suggested that the order for C. difficile–infection testing be reconsidered. This alert was no more than a suggestion, but it did reduce C. difficile–infection testing orders by 25% at first.
“The problem was that the alert lost effect over time as people got used to seeing it and clicked right through it,” Dr. Drees explained.
Despite the diminishing effect of the soft stop, no further steps were planned until a new set of data alerted the infectious disease department that C. difficile–infection rates were higher than benchmarks. This prompted concern among the hospital leadership and led to creation of a multidisciplinary team that was given the task to dig deeper for the source of problems and develop strategies to lower rates of inappropriate testing.
When that team did their initial analysis, what really came to the front was that about half the cases that had been identified as hospital-onset C. difficile were likely only C. difficile colonizations. They either had received laxatives prior to their test or they did not have significant diarrhea,” Dr. Drees said.
It was this finding that prompted a hard stop protocol to be built into C. difficile–infection test orders. In this protocol, which is executed only in patients who have been hospitalized for at least 36 hours, two conditions must be met sequentially for the testing order to proceed. The first is there must be documentation of at least two episodes of diarrhea in the prior 24 hours. If this condition is met, then the ordering system asks for verification that the patient has not received a laxative in the prior 24 hours.
“If either of these criteria are not met, the order can only proceed if the clinician calls the lab for an override,” Dr. Drees explained. Although the person answering the phone in the laboratory does not require any additional documentation or justification, the person ordering the test must enter the name of the person in the laboratory with whom they spoke. If this field is not filled in, the order will not proceed.
Prior to the hard stop, there was an average of 12 C. difficile–infection tests ordered per day. After the hard stop, the average fell to 7 per day, a 42% decline, according to Dr. Drees. C. difficile-infection cases did not increase, and there were no incidences of delayed diagnosis resulting in adverse clinical consequences.
Of the 157 overrides on the hard stop, representing 15% of all orders, only 11% produced a positive C. difficile-infection result. It was noted that almost one third of the overrides did not follow the protocol.
“What I mean is that they did not actually call the lab. They put in their own name [for the field requiring the name of a lab worker] or they put in Mickey Mouse or they put in something, so the order would proceed,” Dr. Drees said. After followup in those cases, “we have not had repeat offenders.”
Even a hard stop is likely to have diminishing efficacy over time as clinicians identify work-arounds, Dr. Drees acknowledged. For example, there is concern that therapy for CDI will be ordered without testing, although this has not yet been detected. However, the hard stop has been more effective and shown a longer duration of effect than the soft stop, according to Dr. Drees. Although Dr. Drees acknowledged that there have been exceptions, the hard stop has “generally been well accepted.”
Dr. Drees reported that she has no financial relationships relevant to this topic.

Faster multiplex PCR improved management of pediatric acute respiratory illness
SAN DIEGO – Switching to a faster, more comprehensive multiplex PCR viral respiratory assay enabled a hospital to discharge young children with acute respiratory illnesses sooner, prescribe oseltamivir more often, and curtail the use of antibiotics and thoracic radiography, Rangaraj Selvarangan, PhD, reported at an annual meeting on infectious disease.
The study shows how rapid multiplex PCR testing can facilitate antimicrobial stewardship, said Dr. Selvarangan, who is a professor at the University of Missouri Kansas City School of Medicine and director of the microbiology laboratory at Children’s Mercy Kansas City. “Our antimicrobial stewardship programs monitors these test results daily, add notes, and make recommendations on antibiotic choices,” he said.
For the study, the researchers compared hospital records from December 2008 through May 2012, when Children’s Mercy hospital used the Luminex xTAG Respiratory Viral Panel, with records from August 2012 through June 2015, after the hospital had switched over to the Biofire FilmArray Respiratory Panel. FilmArray targets the same 17 viral pathogens as the Luminex panel, but also targets Bordetella pertussis, Chlamydia pneumoniae, and Mycoplasma pneumoniae, seasonal influenza A, parainfluenza type 4, and four coronaviruses.
The study included children aged up to 2 years who were not on immunosuppressive medications, in the NICU, or hospitalized for more than 7 days. For this population, the two panels yielded similar rates of positivity overall (about 60%) and for individual viruses, Dr. Selvarangan said. A total of 810 patients tested positive for at least one virus on the Luminex panel, and 2,096 patients tested positive on FilmArray. Results for FilmArray were available within a median of 4 hours, versus 29 hours for Luminex (P less than .001). The prevalence of empiric antibiotic therapy was 44% during the Luminex era and 28% after the hospital switched to FilmArray (P less than .001). Rates of antibiotic discontinuation rose from 16% with Luminex to 23% with FilmArray (P less than .01). Strikingly, oseltamivir prescriptions rose five-fold (from 17% to 85%; P less than .001) after the hospital began using FilmArray, which covers seasonal influenza. Finally, use of chest radiography fell significantly in both infants and older children after the hospital began using FilmArray instead of Luminex.
Clinicians might have become more comfortable interpreting molecular test results over time, which could have altered their clinical decision-making and thereby biased the study results, Dr. Selvarangan noted. Although at least four other single-center retrospective studies have linked multiplex PCR assays to better antibiotic stewardship, this study is one of the first to directly compare clinical outcomes between two assays, he added. More studies are needed to help guide choice of multiplex assays, whose cost remains a major barrier to widespread use, he concluded.
Dr. Selvarangan disclosed grant support from both Biofire Diagnostics and Luminex corporation, and an advisory relationship with BioFire.

Study eyes factors that may trigger breakthrough bacteremia
SAN DIEGO – , according to a detailed study of six isolates.
“Both patient and microbe factors can contribute to treatment failure, even involving pan-susceptible isolates,” Andrew Berti, PharmD, PhD, said in an interview prior to an annual scientific meeting on infectious diseases.
The researchers presented the case of a patient who experienced multiple episodes of breakthrough Staphylococcus aureus bacteremia over a period of 5 years in the setting of appropriately dosed antimicrobial suppressive therapy. They recovered six clinical bloodstream isolates from the patient during distinct episodes of methicillin-susceptible S. aureus (MSSA) bacteremia, and it was determined that a central line infection was the source for each episode. Isolates recovered were susceptible to the individual therapies received, which included oxacillin, daptomycin, and dalbavancin. The researchers used Illumina technology to collect bacterial whole genome sequence data. “Relatively little is known about bacterial evolution during human infection as these tend to be acute, rapidly resolved events,” Dr. Berti said. “This case was unique in that we could observe changes to a pathogen over a more than 6 years period as it adapted to survive host defenses and multiple antibiotic interventions.”
The researchers discovered that the first two isolates (ST256) and the last four isolates (ST5) “represent distinct populations and suggest that a distinct MSSA strain displaced the previous population between bacteremia episodes 2 and 3,” they wrote in their abstract. “Of note, all of these strains were able to survive and establish breakthrough bacteremias despite favorable susceptibility profiles to the agents used as suppressive therapy. Although the MICs remain low and in the susceptible range to oxacillin, daptomycin, and dalbavancin, these isolates progressively developed significant antimicrobial tolerance phenotypes, which coincided with mutations in walK (yycG), htrA2, ftsW, ebh, and ileS that may be advantageous to survival under antibiotic pressure.”
Dr. Berti acknowledged certain limitations of the analysis, including the inability to test for heteroresistance to some antibiotics, which may also contribute to treatment failure. “Specific therapeutic interventions that coincide with bacterial population changes are not necessarily causative of those changes,” he said. One of the study authors, Warren Rose, PharmD, disclosed having received research grants, speaker honoraria, and/or consulting fees from Theravance, Merck, The Medicines Company and Visante, Inc. All other authors reported having no financial disclosures.

“Both patient and microbe factors can contribute to treatment failure, even involving pan-susceptible isolates,” Andrew Berti, PharmD, PhD, said in an interview prior to an annual scientific meeting on infectious diseases.
The researchers presented the case of a patient who experienced multiple episodes of breakthrough Staphylococcus aureus bacteremia over a period of 5 years in the setting of appropriately dosed antimicrobial suppressive therapy. They recovered six clinical bloodstream isolates from the patient during distinct episodes of methicillin-susceptible S. aureus (MSSA) bacteremia, and it was determined that a central line infection was the source for each episode. Isolates recovered were susceptible to the individual therapies received, which included oxacillin, daptomycin, and dalbavancin.

New data dissect global burden of scabies
Scabies hits hardest in tropical parts of the world, and children and teens are most affected by the condition, based on data from a global epidemiological assessment.
“,” wrote Chante Karimkhani, MD, of the University of Colorado, Aurora, and her colleagues. To estimate the global impact of scabies, the researchers used the Global Burden of Disease (GBD) Study 2015, which included literature searches between 1980 and 2014 in both English and Spanish.
Overall, the prevalence of scabies worldwide was 204,151,715, and the age-standardized DALYs was 71/100,000 people. The highest DALYs in terms of world regions were reported in East Asia (136/100,000), Southeast Asia (135/100,000) the region described as Oceania (120/100,000) (which included American Samoa, Fiji, Guam, Marshall Islands, Northern Mariana Islands, Papua New Guinea, Samoa, Solomon Islands, and others), tropical Latin America (100/100,000), and South Asia (69/100,000). Scabies caused 0.21% of DALYs from all the conditions that are studied by GBD 2015 globally. The mean percent change in age-standardized DALY from 1990 to 2015 increased 22% in North America, but the age-standardized DALY still remained less than 5/100,000.
In addition, global DALYs from scabies skin infection were highest in children aged 1-4 years (116/100,000 individuals) and adolescents aged 15-19 years (102/100,000). DALYs were not significantly different between men and women across all age groups, Dr. Karimkhani and her associates reported.
“As a worldwide epidemiological assessment, GBD 2015 provides broad and frequently updated measures of scabies burden in terms of skin effects. These global data might help guide research protocols and prioritization efforts and focus scabies treatment and control measures,” the researchers said.
Of note is that these analyses do not include information about complications of scabies such as impetigo, local and systemic bacterial infections, glomerulonephritis, and rheumatic fever.
The study was funded by the Bill and Melinda Gates Foundation. The researchers had no financial conflicts to disclose.

Behavioral approach to appropriate antimicrobial prescribing in hospitals: The DUMAS study
Clinical question: How effective is an antimicrobial stewardship approach grounded in behavioral theory and focused on preserving prescriber autonomy and participation in improving appropriateness of antimicrobial prescribing in hospitals?
Background: Antimicrobial stewardship programs aim to achieve the goal of improving antimicrobial prescribing. This leads to significant benefits, including decreased antimicrobial resistance, improved clinical outcomes (lower morbidity and mortality), and lower health care costs. Stewardship programs do not often focus on the human behavior element of the prescribing physicians. Changing antimicrobial prescribing is a complex behavioral process, and there is a known persistent resistance between prescribers and the stewardship team. In a simple sense, this resistance is generated by tension created when prescribers do not have autonomy.
Previous studies that used interventions based on behavioral theory found promising results, but none of them were in a hospital setting. Rather, most of these studies had a narrow focus of respiratory tract infections in outpatient clinics.
Setting: Seven clinical departments (two medical, three surgical, and two pediatric) in a tertiary care medical center and a general teaching hospital, both in Amsterdam. The first hospital was a 700-bed tertiary care center with salaried specialists, while the second hospital was a 550-bed general medical center with self-employed specialists.
Synopsis: During a baseline period of 16 months and an intervention period of 12 months, physicians who prescribed systemic antimicrobial drugs for any indication were included in the study. In all, 1,121 patient cases with 700 prescriptions were studied during the baseline period and 882 patient cases with 531 prescriptions were studied during the intervention period. The intervention was as follows: Prescribers were offered a free choice of how to improve their antimicrobial prescribing. They were stimulated to choose interventions with higher potential for success based on a root cause analysis of inappropriate prescribing. The study was inspired by the participatory action research paradigm, which focuses on collaboration and empowerment of the stakeholders in the change process. In this study, prescribers were given reports of root cause analysis of their prior prescribing patterns. Then, they were invited to choose and codevelop one or more interventions that were tailored and individualized to improve their own prescribing. This approach draws on the following three behavioral principles: 1) respect for the prescriber’s autonomy to avoid feelings of resistance; 2) the inclination that people have to value a product higher and feel more ownership of it if they made it themselves (the IKEA effect); 3) the tendency of people to follow up on an active and public commitment.
The primary outcome was antimicrobial appropriateness, measured with a validated appropriateness assessment instrument. One of three infectious disease specialists assessed the adult prescriptions, and one of three infectious disease/immunology pediatricians assessed the pediatric prescriptions for appropriateness. Appropriateness criteria were as follows: indication, choice of antimicrobial, dosage, route, and duration. A secondary outcome was antimicrobial consumption, reported as days of therapy per 100 admissions per month. Other outcomes were changes in specific appropriateness categories, intravenous antimicrobial consumption, consumption of specific antimicrobial subgroups, and length of hospital stay.
The mean antimicrobial appropriateness increased from 64.1% at intervention start to 77.4% at 12-month follow-up (+13.3%; relative risk, 1.17; 95% CI, 1.04-1.27), without a change in slope. Antimicrobial consumption remained the same during both study periods. Length of hospital stay did not change relative to the start of the intervention approach.
This is the first study of its kind, as a hospital antimicrobial stewardship program study grounded in behavioral science, with the key element being the free choice allowed to the prescribers, who made their own autonomous decisions about how to improve their prescribing. The authors hypothesize that the prescribers felt relatively nonthreatened by their approach since the prescribers maintained their free will to change their own behavior if so desired. The prescribers were given a free intervention choice. For example, they could have just chosen “education” as an easy out; however, the root cause analysis seemed to be an impetus for the prescribers to choose interventions that would be more effective. A prior study in a nursing home setting was unsuccessful; aside from other differences, that study used a predetermined set of interventions, thus lacking the autonomy and IKEA effect seen in this study.
Bottom line: Use of a behavioral approach that preserves prescriber autonomy resulted in an increase in antimicrobial appropriateness sustained for at least 12 months. The intervention is effective, inexpensive, and transferable to various health care settings.

FDA grants drug orphan designation to treat cGVHD
The US Food and Drug Administration (FDA) has granted orphan drug designation to KD025 for the treatment of chronic graft-versus-host disease (cGVHD).
KD025 is a Rho-associated coiled-coil kinase (ROCK) inhibitor being developed by Kadmon Holdings, Inc.
The drug is currently under investigation in a phase 2 trial of adults with steroid-dependent or steroid-refractory cGVHD and active disease.
This dose-finding study has enrolled 48 patients divided into 3 cohorts in which patients receive KD025 at 200 mg once daily, 200 mg twice daily, or 400 mg once daily. The patients were enrolled sequentially following a safety assessment of each cohort.
In July, Kadmon Holdings, Inc. released a preliminary analysis of data from the lowest-dose cohort (n=17, 200 mg once daily).
The overall response rate in this cohort was 71% (12/17). Of responders remaining on KD025 through week 24, 89% (8/9) sustained responses. Sixty-seven percent (8/12) of responders saw an improvement in symptoms, as measured by the Lee cGVHD Symptom Scale score.
In addition to the 12 responders, 3 patients had stable disease and were still on KD025 through week 24. So an overall clinical benefit (response and stable disease) occurred in 88% (15/17) of patients.
Sixty-seven percent (8/12) of responders had a reduction in steroid doses, and 67% (4/6) of responders on tacrolimus had a reduction in tacrolimus doses.
There were no drug-related serious adverse events or drug-related elevations in liver function tests reported.
Kadmon Holdings, Inc. plans to present additional data from this study toward the end of this year.
About orphan designation
The FDA grants orphan designation to products intended to treat, diagnose, or prevent diseases/disorders that affect fewer than 200,000 people in the US.
The designation provides incentives for sponsors to develop products for rare diseases. This may include tax credits toward the cost of clinical trials, prescription drug user fee waivers, and 7 years of market exclusivity if the product is approved. ![]()

There were no drug-related serious adverse events or drug-related elevations in liver function tests reported.
Kadmon Holdings, Inc. plans to present additional data from this study toward the end of this year.
About orphan designation
The FDA grants orphan designation to products intended to treat, diagnose, or prevent diseases/disorders that affect fewer than 200,000 people in the US.
The designation provides incentives for sponsors to develop products for rare diseases. This may include tax credits toward the cost of clinical trials, prescription drug user fee waivers, and 7 years of market exclusivity if the product is approved. ![]()
Duty vs. confidentiality
Question: During an office visit, a patient confided in his primary care provider his intention to go on a shooting spree. When pressed, he admitted he owned a firearm, but did not truly intend to carry out the act. He denied having a specific target location or victim in mind. The primary care provider (PCP) opted to counsel the patient, and continued him on his antidepressant medication. The PCP did not make a referral to a psychiatrist. Several weeks later, the patient put his threat into action, shooting and injuring several innocent shoppers at a mall.
In a lawsuit against the PCP, which of the following is best?
A. It is unethical for the PCP to report this threat, because it violates the principle of confidentiality.
B. Failure to warn under the circumstances definitely makes the physician liable.
C. The PCP is liable under the Tarasoff doctrine.
D. Without a named victim, there is no one to warn.
E. Whether the PCP is liable may turn on the issue of foreseeability, and an immediate referral to a psychiatrist would have been a more prudent course of action.
Answer: E. One of the physician’s sacred promises is to maintain patient confidentiality. It is more than an unspoken contractual agreement; it’s a central component of trust, without which the doctor-patient relationship cannot exist. Indeed, Hippocrates had cautioned, “whatever in connection with my professional practice, or not in connection with it, I see or hear, in the life of men, which ought not to be spoken of abroad, I will not divulge as reckoning that all should be kept secret.”
Thus, the recent expansive decision handed down by the Washington state Supreme Court stunned many mental health professionals.1 In Volk v. DeMeerleer, a clinic patient had confided in his psychiatrist over 9 years of therapy his suicidal and homicidal ideations. He eventually went on to kill his former girlfriend and one of her sons, and then committed suicide. The psychiatrist did not have full control of this clinic patient, nor had the patient named a specific victim. Nevertheless, the Volk court held that the doctor’s duty extended to any foreseeable harm by the patient, leaving it up to the jury to decide on the issue of foreseeability.
The court held that the psychiatrist had a “special relationship” with the victims, because he had a duty to exercise reasonable care to act, consistent with the standards of the mental health profession, in order to protect the foreseeable victims.
The court reasoned that some ability to control the patient’s conduct is sufficient for the “special relationship” and the consequent duty of care to exist, writing: “We find that absolute control is unnecessary, and the actions available to mental health professionals, even in the outpatient setting, weigh in favor of imposing a duty.” The court also noted that a psychiatrist’s obligation to protect third parties against patients’ violence would normally set aside confidentiality and yield to greater societal interests.
The vexing issue of compromising confidentiality in the name of protecting public safety had its genesis in the famous Tarasoff v. Regents of University of California case.2
In Tarasoff, the California court imposed a legal duty on a college psychologist to warn an intended victim of harm, even though that meant breaching confidentiality in a professional relationship. A jilted patient had confided in the university psychologist his intention to kill his ex-girlfriend. The information, though shared with campus security, was not released to the intended victim, whom the patient stabbed to death 2 months later.
The court reasoned that the protection of public safety was more important than the sanctity of the doctor-patient confidentiality relationship, pointing out: “We recognize the public interest in supporting effective treatment of mental illness and in protecting the rights of patients to privacy and the consequent public importance of safeguarding the confidential character of psychotherapeutic communication. Against this interest, however, we must weigh the public interest in safety from violent assault. ... In this risk-infested society, we can hardly tolerate the further exposure to danger that would result from a concealed knowledge of the therapist that his patient was lethal.”
Following Tarasoff, it is generally accepted that there is no affirmative duty to warn where there is no readily identifiable victim. In a subsequent case, the same court explained that “the duty to warn depends upon and arises from the existence of a prior threat to a specific identifiable victim. In those instances in which the released offender poses a predictable threat of harm to a named or readily identifiable victim or group of victims who can be effectively warned of the danger, a releasing agent may well be liable for failure to warn such persons. Despite the tragic events underlying the present complaint, plaintiffs’ decedent was not a known, identifiable victim, but rather a member of a large, amorphous public group of potential targets. Under these circumstances, we hold that County had no affirmative duty to warn plaintiffs, the police, the mother of the juvenile offender, or other local parents.”3
Commentators have suggested that such post-Tarasoff cases, coupled with the advent of state statutes that codify Tarasoff, have witnessed a retreat from imposing on clinicians a duty to warn.4 By dispensing with the control and “readily identifiable victim” elements, Volk appears to contradict this perceived trend. Foreseeability may turn out to be the dispositive issue.
Some have speculated whether Volk’s expanded view will apply to other professionals such as a family practitioner or even a school counselor. Physicians who are not experienced in treating mental health patients will do well to promptly refer their unstable patients to a specialist psychiatrist.
Volk can also be read as offering judicial insight into patients who pose a health hazard by insisting on operating a vehicle against medical advice. In its 2012 Code of Medical Ethics, the American Medical Association had this to say: “In situations where clear evidence of substantial driving impairment implies a strong threat to patient and public safety, and where the physician’s advice to discontinue driving privileges is ignored, it is desirable and ethical to notify the department of motor vehicles.”5
That is now replaced in the AMA code with a broader version covering the duty to disclose: “Physicians may disclose personal health information without the specific consent of the patient ... to other third parties situated to mitigate the threat when in the physician’s judgment there is a reasonable probability that: (i) the patient will seriously harm him/herself; or (ii) the patient will inflict serious physical harm on an identifiable individual or individuals.”6
Under Volk, physicians are now more likely to forsake confidentiality in the name of public safety – even in the absence of a readily identifiable potential victim.

Baseline lab data is class specific for biologics to treat psoriasis patients
said April Armstrong, MD, of the University of Southern California, Los Angeles.
Keep class-specific considerations in mind when collecting baseline lab data to help support the success of biologics in treating psoriasis, Dr. Armstrong said at the annual Coastal Dermatology Symposium.
When clinicians consider biologics, they must balance efficacy, safety, convenience, and costs of treatment, Dr. Armstrong said.
She addressed general considerations when selecting biologics for psoriasis and stressed the importance of assessing patients for tuberculosis and reviewing underlying cancer risk. Confirm that a patient has no active infections and consider whether a patient has completed all age-appropriate immunizations. Consider a complete blood count and metabolic panel for the following biologics:
- Ustekinumab: Baseline HIV or pregnancy test, and a TB evaluation at baseline as well as annual monitoring.
- Etanercept, adalimumab, infliximab: Baseline TB evaluation and screening hepatitis panel, liver function tests, and blood count, with option to add pregnancy test or HIV test. A liver function test/hepatitis panel is indicated annually, and TB should be monitored annually. Be cautious about using this class of drugs in patients with heart failure, and verify the absence of demyelinating disease in patients prior to prescribing this class of drugs.
- Guselkumab: Baseline TB evaluation, possible pregnancy or HIV tests, followed by annual TB evaluation.
- Secukinumab, ixekizumab, and brodalumab: Baseline TB evaluation, consider HIV or pregnancy tests, followed by annual TB evaluation. Be cautious about using this class of drugs in patients with ulcerative colitis or Crohn’s disease; assess and counsel for increased risk of suicidality when considering brodalumab.
Beyond the general considerations, several other factors can help maximize success with particular biologics, Dr. Armstrong said at the meeting, which is jointly presented by the University of Louisville and Global Academy for Medical Education.
The number of injections given in the first year, which range from 5 (ustekinumab) to 64 (etanercept) is an important consideration for some patients, Dr. Armstrong noted; the number of injections for the remaining biologics are guselkumab, 8; ixekizumab, 17; brodalumab and adalimumab, both 27, and secukinumab, 32. In addition, the IL-17 inhibitors carry some risk of oral candidiasis and inflammatory bowel disease.

EXPERT ANALYSIS FROM THE COASTAL DERMATOLOGY SYMPOSIUM
Trump administration narrows contraceptive mandate
The Trump administration has issued new rules allowing more employers to opt out of the Affordable Care Act’s contraceptive mandate, a move that physician leaders say could sharply restrict women’s ability to access birth control and lead to more unplanned pregnancies.
Under two regulations, issued Oct. 6 in the Federal Register, an expanded group of employers and insurers can get out of covering contraception methods by objecting on either religious or moral grounds. The new policy will “better balance the government’s interest in promoting coverage for contraceptive and sterilization services with the government’s interests in providing conscience protections for entities with sincerely held moral convictions,” according to the rule on moral exemptions issued by the departments of Health & Human Services, Labor, and Treasury.
The American Congress of Obstetricians and Gynecologists denounced the new rules as a move that will negatively impact the health of women and families by limiting access to essential preventive care.
“Reducing access to contraceptive coverage threatens to reverse the tremendous progress our nation has made in recent years in lowering the unintended pregnancy rate,” ACOG President Haywood L. Brown said in a statement. “Instead of fulfilling its mission ‘to enhance and protect the health and well-being of all Americans,’ HHS leaders under the current administration are focused on turning back the clock on women’s health.”
The ACA initially required all employers to cover birth control for employees with no copayments, except for group health plans of “religious employers,” which were deemed exempt. Those religious employers were, for the most part, churches and other houses of worship. After multiple complaints and legal challenges, the Obama administration later created a workaround for another group – nonprofit religious employers – to opt out of the mandate. However, critics argued the process itself was a violation of their religious freedom. The issue led to the case of Zubik v. Burwell, a legal challenge over the mandate exemption that went before the U.S. Supreme Court in March 2016.
But the issue remained unresolved. In May 2016, the Supreme Court vacated the lower court rulings related to Zubik v. Burwell and remanded the case back to the four appeals courts that had originally ruled on the issue.
Under the new Oct. 6 regulations, any employer or insurer can halt their coverage of contraceptive services if they have religious beliefs or moral convictions against covering birth control. They need not have a specific religious affiliation to do so. States would determine how companies can make these decisions.
It’s unclear how many women and employers will be impacted. In its rule on religious exemptions, HHS estimated that 109 entities will use this voluntary accommodation moving forward. The department also estimated that the expanded religious exemptions will impact the contraceptive costs of about 31,700 women of childbearing age that use the contraception coverage.
According to research by the Kaiser Family Foundation, 1 in 10 nonprofit organizations with at least 1,000 workers sought an accommodation to not provide Affordable Care Act–required contraceptive coverage to their employees in 2015, but instead allow workers to access the copay-free coverage separately. Three percent of all nonprofits with at least 10 workers sought some kind of accommodation, according to the research. For the smallest of organizations (10-199 workers), the accommodation request rate was 2%, while 5% of organizations with 200-999 workers requested an accommodation.
The American College of Physicians expressed their disappointment with the new regulation, saying that it could lead to more out-of-pocket costs for women who currently receive free contraception.
“Our concern is grounded on our long-standing policy that all Americans should have coverage for evidence-based medical services, including preventive services like contraception,” Jack Ende, MD, ACP president said in a statement. “We are concerned that allowing employers to carve out exemptions to the ACA’s requirements that health insurance plans cover evidence-based preventive services without cost sharing, including but not necessarily limited to contraception, will create substantial barriers to patients receiving appropriate medical care as recommended by their physicians.”
In a statement, national pro-life group Susan B. Anthony List declared the new rules to be a “huge victory for conscience rights and religious liberty in America,” noting that it would exempt their group as a moral objector to contraception.

“Reducing access to contraceptive coverage threatens to reverse the tremendous progress our nation has made in recent years in lowering the unintended pregnancy rate,” ACOG President Haywood L. Brown said in a statement. “Instead of fulfilling its mission ‘to enhance and protect the health and well-being of all Americans,’ HHS leaders under the current administration are focused on turning back the clock on women’s health.”
The ACA initially required all employers to cover birth control for employees with no copayments, except for group health plans of “religious employers,” which were deemed exempt. Those religious employers were, for the most part, churches and other houses of worship. After multiple complaints and legal challenges, the Obama administration later created a workaround for another group – nonprofit religious employers – to opt out of the mandate. However, critics argued the process itself was a violation of their religious freedom. The issue led to the case of Zubik v. Burwell, a legal challenge over the mandate exemption that went before the U.S. Supreme Court in March 2016.
But the issue remained unresolved. In May 2016, the Supreme Court vacated the lower court rulings related to Zubik v. Burwell and remanded the case back to the four appeals courts that had originally ruled on the issue.
Under the new Oct. 6 regulations, any employer or insurer can halt their coverage of contraceptive services if they have religious beliefs or moral convictions against covering birth control. They need not have a specific religious affiliation to do so. States would determine how companies can make these decisions.
It’s unclear how many women and employers will be impacted. In its rule on religious exemptions, HHS estimated that 109 entities will use this voluntary accommodation moving forward. The department also estimated that the expanded religious exemptions will impact the contraceptive costs of about 31,700 women of childbearing age that use the contraception coverage.
According to research by the Kaiser Family Foundation, 1 in 10 nonprofit organizations with at least 1,000 workers sought an accommodation to not provide Affordable Care Act–required contraceptive coverage to their employees in 2015, but instead allow workers to access the copay-free coverage separately. Three percent of all nonprofits with at least 10 workers sought some kind of accommodation, according to the research. For the smallest of organizations (10-199 workers), the accommodation request rate was 2%, while 5% of organizations with 200-999 workers requested an accommodation.
The American College of Physicians expressed their disappointment with the new regulation, saying that it could lead to more out-of-pocket costs for women who currently receive free contraception.
“Our concern is grounded on our long-standing policy that all Americans should have coverage for evidence-based medical services, including preventive services like contraception,” Jack Ende, MD, ACP president said in a statement. “We are concerned that allowing employers to carve out exemptions to the ACA’s requirements that health insurance plans cover evidence-based preventive services without cost sharing, including but not necessarily limited to contraception, will create substantial barriers to patients receiving appropriate medical care as recommended by their physicians.”
In a statement, national pro-life group Susan B. Anthony List declared the new rules to be a “huge victory for conscience rights and religious liberty in America,” noting that it would exempt their group as a moral objector to contraception.

The Trump administration has issued new rules allowing more employers to opt out of the Affordable Care Act’s contraceptive mandate, a move that physician leaders say could sharply restrict women’s ability to access birth control and lead to more unplanned pregnancies.
Under two regulations, issued Oct. 6 in the Federal Register, an expanded group of employers and insurers can get out of covering contraception methods by objecting on either religious or moral grounds. The new policy will “better balance the government’s interest in promoting coverage for contraceptive and sterilization services with the government’s interests in providing conscience protections for entities with sincerely held moral convictions,” according to the rule on moral exemptions issued by the departments of Health & Human Services, Labor, and Treasury.
The American Congress of Obstetricians and Gynecologists denounced the new rules as a move that will negatively impact the health of women and families by limiting access to essential preventive care.
