Nurse Standing Orders for Buprenorphine Follow-Up Care in a Community Health Center Network.

BACKGROUND: Less than 20% of individuals with opioid use disorder (OUD) are receiving a medication treatment for OUD in the United States. Though nurses can assume critical roles in outpatient models of OUD care, there are no published reports of buprenorphine standing orders for nurses that guide a nuanced response for patients returning as expected versus those re-engaging after a treatment lapse, without requiring real-time prescriber consultation. METHODS: Standing orders for buprenorphine were created with multiple stakeholders within an urban community health center that includes traditional clinics as well as non-traditional homeless care sites. After more than two years of use, an anonymous survey assessed staff perception of usability and safety of the standing orders using the validated system usability scale (SUS) and a 5-item Likert scale. Patient retention rates at 12 and 18 months were compared for sites that were early- and late-adopters of the standing orders. RESULTS: Of 24 clinicians and 7 nurses who responded to the survey, 46% had used the standing orders. More than 85% reported a perception that the standing orders improved team-based care and increased access to buprenorphine refills. None reported any safety concerns. The median SUS score was 75.0 (SD 15.4), rated as "excellent". There was no statistically significant difference in 12- or 18-month retention rates between early- and late-adopter sites of the standing orders. CONCLUSIONS: Nurse standing orders for buprenorphine follow-up and re-engagement care are feasible, usable and perceived as safe in varied community health center settings.

Clinical pathways for primary care: current use, interest and perceived usability.

Objective: Translating clinical evidence to daily practice remains a challenge and may improve with clinical pathways. We assessed interest in and usability of clinical pathways by primary care professionals. Methods: An online survey was created. Interest in pathways for patient care and learning was assessed at start and finish. Participants completed baseline questions then pathway-associated question sets related to management of 2 chronic diseases. Perceived pathway usability was assessed using the system usability scale. Accuracy and confidence of answers was compared for baseline and pathway-assisted questions. Results: Of 115 participants, 17.4% had used clinical pathways, the lowest of decision support tool types surveyed. Accuracy and confidence in answers significantly improved for all pathways. Interest in using pathways daily or weekly was above 75% for the respondents. Conclusion: There is low utilization of, but high interest in, clinical pathways by primary care clinicians. Pathways improve accuracy and confidence in answering written clinical questions.

A Countercultural Heritage: Rediscovering the Relationship-Centered and Social Justice Roots of Family Medicine-A Perspective from the Keystone IV Conference.

The 2015 G. Gayle Stephens Keystone conference convened a cohort of primary care professionals to discuss what promises personal physicians will make to their patients going forward. New physicians were prompted to rediscover the foundational values of and historic context for family medicine. At the heart of this rediscovery was learning of the writings and teachings of Dr. G. Gayle Stephens, a founder of family medicine who emphasized the essentiality of relationship-centered care and social justice to the new specialty. Dr. Stephens viewed family medicine as being in a countercultural relationship to mainstream medicine, as family medicine fought for justice and equity in an inequitable and fragmented health care system. Here we argue that by reaffirming and renewing this countercultural heritage the new generation of family physicians will have better clarity in approaching the many challenges in health care today. Particularly for trainees and new physicians, the historic lens offered by Dr. Stephens's writing and other foundational documents allows us to better see ourselves in a trajectory of ongoing health care reform.

Residency Curricula on Physician-Pharmaceutical Industry Interaction: A CERA Study.

BACKGROUND AND OBJECTIVES: Physician interaction with pharmaceutical representatives results in less evidence-based prescribing and increased costs. Many organizations have called for strong conflict of interest policies in academic institutions. Implementing policy without educational interventions may not adequately address the influence of industry on physician prescribing patterns. The objective of this study is to assess the implementation and content of family medicine residency curricula on the physician-pharmaceutical industry relationship. METHODS: We surveyed US family medicine program directors using the Council of Academic Family Medicine Educational Research Alliance (CERA) platform. The presence of a formal curriculum on the physician-industry interaction and specific curricular elements (ethics of interaction, understanding detailing sessions and advertisements, use of unbiased pharmaceutical information) were the outcome measures of interest. RESULTS: Fifty-two percent (212 of 406) of program directors responded. Forty percent (95% confidence interval [CI]: 33%--46%) reported having a formal curriculum on physician-pharmaceutical industry interactions. The presence of a formal curriculum was more likely in residencies permitting interaction with industry (52% [48/92] versus 30% [36/120]) or with a university affiliation (43% [75/173] versus 19% [7/36]). The use of unbiased sources of information relating to pharmaceutical products and the ethics of the physician-pharmaceutical industry relationship were the most common curricular elements (59% and 55%, respectively). CONCLUSIONS: This study shows that less than half of US family medicine programs have a curriculum addressing physician-industry interactions. Further research on the efficacy of and barriers to curriculum creation and implementation is warranted.

A cost-effectiveness analysis of alternative HIV retesting strategies in sub-saharan Africa.

BACKGROUND: Guidelines in sub-Saharan Africa on when HIV-seronegative persons should retest range from never to annually for lower-risk populations and from annually to every 3 months for high-risk populations. METHODS: We designed a mathematical model to compare the cost-effectiveness of alternative HIV retesting frequencies. Cost of HIV counseling and testing, linkage to care, treatment costs, disease progression, and mortality, and HIV transmission are modeled for three hypothetical cohorts with posited annual HIV incidence of 0.8%, 1.3%, and 4.0%, respectively. The model compared costs, quality-adjusted life-years gained, and secondary infections averted from testing intervals ranging from 3 months to 30 years. Input parameters from sub-Saharan Africa were used and explored in sensitivity analyses. RESULTS: Accounting for secondary infections averted, the most cost-effective testing frequency was every 7.5 years for 0.8% incidence, every 5 years for 1.3% incidence, and every 2 years for 4.0% incidence. Optimal testing strategies and their relative cost-effectiveness were most sensitive to assumptions about HIV counseling and testing and treatment costs, rates of CD4 decline, rates of HIV transmission, and whether tertiary infections averted were taken into account. CONCLUSIONS: While higher risk populations merit more frequent HIV testing than low risk populations, regular retesting is beneficial even in low-risk populations. Our data demonstrate benefits of tailoring testing intervals to resource constraints and local HIV incidence rates.

The FliK protein and flagellar hook-length control.

The bacterial flagellum is a highly complex prokaryotic organelle. It is the motor that drives bacterial motility, and despite the large amount of energy required to make and operate flagella, motile organisms have a strong adaptive advantage. Flagellar biogenesis is both complex and highly coordinated and it typically involves at least three two-component systems. Part of the flagellum is a type III secretion system, and it is via this structure that flagellar components are exported. The assembly of a flagellum occurs in a number of stages, and the "checkpoint control" protein FliK functions in this process by detecting when the flagellar hook substructure has reached its optimal length. FliK then terminates hook export and assembly and transmits a signal to begin filament export, the final stage in flagellar biosynthesis. As yet the exact mechanism of how FliK achieves this is not known. Here we review what is known of the FliK protein and discuss the evidence for and against the various hypotheses that have been proposed in recent years to explain how FliK controls hook length, FliK as a molecular ruler, the measuring cup theory, the role of the FliK N terminus, the infrequent molecular ruler theory, and the molecular clock theory.
