RESUMEN

BACKGROUND: Direct-acting antiviral medications have the potential to eliminate the hepatitis C virus (HCV) epidemic among people who inject drugs; yet, suboptimal adherence remains a barrier. Directly observed treatment (DOT), an effective strategy for optimizing adherence, has been frequently implemented in opioid treatment programs but less commonly in community health settings due to the heavy burden of daily visits. An alternative is video-observed therapy (VOT), which uses mobile health technology to monitor adherence. VOT has not been widely studied among people who inject drugs with HCV. OBJECTIVE: This qualitative study, part of a larger implementation evaluation, investigates stakeholder perceptions and experiences with VOT in Project HERO (Hepatitis C Real Outcomes), a multisite pragmatic trial testing treatment delivery models for people who inject drugs with HCV. Our goal was to understand the potential barriers and facilitators to the implementation of the VOT technology. METHODS: Qualitative interviews were conducted with 27 Project HERO study staff and 7 patients. Interviews focused on perceptions and experiences with the VOT app and barriers and facilitators to implementation. Team meeting minutes over the first 2 years of the project were transcribed. A coding system was developed and applied to the data. We summarized thematic data and compared participant perceptions to generate a close understanding of the data. RESULTS: Frequent barriers to VOT included mechanical failure, stolen or lost phones, and a steep learning curve for participants and study staff. In sites with older and less technically skilled participants, staff found it difficult to implement the VOT app. Research staff found that the routine monitoring of app use led to closer engagement with participants. This was both a benefit and a potential threat to the validity of this pragmatic trial. Patient participants reported mixed experiences. CONCLUSIONS: VOT may be a useful alternative to DOT for some patients, but it may not be feasible for all. Significant staff involvement may be required.

RESUMEN

BACKGROUND: Underuse of guideline-recommended inhaled corticosteroids (ICS) controller therapy is a risk factor for greater asthma burden. ICS concomitantly used with rescue inhalers (Patient-Activated Reliever-Triggered ICS ['PARTICS']) reduced asthma exacerbations in efficacy trials, but whether PARTICS is effective in pragmatic trials is unknown. OBJECTIVE: We conducted this pilot to determine the feasibility of executing a large-scale pragmatic PARTICS trial and to improve study protocols. METHODS: Four sites recruited 33 Hispanic or black adults with persistent asthma, randomized them approximately 3:1 to intervention or usual care, and followed them for 12 weeks. All participants received asthma guideline-based educational videos; intervention participants received video-based instructions on implementing PARTICS plus usual medications. The study involved 1 randomization visit and monthly questionnaires. Timely questionnaire responses (±2 weeks) were monitored. Participants underwent qualitative phone interviews to assess self-reported adherence to PARTICS and understand barriers to completing study procedures. RESULTS: Timely questionnaire response rates were 61%, 64%, and 70% at 4, 8, and 12 weeks, respectively. Self-reported adherence to PARTICS was 76% (95% confidence interval [CI], 58%-94% [n = 21]), 88% (95%CI, 72%-100% [n = 16]), and 62% (95%CI, 36%-88% [n = 13]) at weeks 1, 6, and 12, respectively. Barriers to completing study procedures included difficulties with questionnaire access, remembering to use ICS and rescue inhalers together, and obtaining refills. Only 22% of participants recognized their short-acting bronchodilator as "reliever" or "rescue." CONCLUSION: Recruitment was feasible within the allocated period. Adherence to PARTICS was incomplete, questionnaire completion was suboptimal, and common rescue inhaler nomenclature usage was limited. We have modified the full study protocol to attempt to improve adherence to PARTICS and minimize barriers to study procedures. CLINICAL TRIALS REGISTRATION: pilot study for 'PeRson EmPowered Asthma Relief' (PREPARE, NCT02995733).

RESUMEN

In many woody dicot plant species, colder temperatures correlate with a greater degree of leaf dissection and with larger and more abundant leaf teeth (the serrated edges along margins). The measurement of site-mean characteristics of leaf size and shape (physiognomy), including leaf dissection and tooth morphology, has been an important paleoclimate tool for over a century. These physiognomic-based climate proxies require that all woody dicot plants at a site, regardless of species, change their leaf shape rapidly and predictably in response to temperature. Here we experimentally test these assumptions by growing five woody species in growth cabinets under two temperatures (17 and 25°C). In keeping with global site-based patterns, plants tend to develop more dissected leaves with more abundant and larger leaf teeth in the cool treatment. Overall, this upholds the assumption that leaf shape responds in a particular direction to temperature change. The assumption that leaf shape variables respond to temperature in the same way regardless of species did not hold because the responses varied by species. Leaf physiognomic models for inferring paleoclimate should take into account these species-specific responses.

RESUMEN

BACKGROUND: For at least the past two decades, medical educators have worked to improve patient communication and health care delivery to diverse patient populations; despite efforts, patients continue to report prejudice and bias during their clinical encounters. Targeted instruction in implicit bias recognition and management may promote the delivery of equitable care, but students at times resist this instruction. Little guidance exists to overcome this resistance and to engage students in implicit bias instruction; instruction over time could lead to eventual skill development that is necessary to mitigate the influence of implicit bias on clinical practice behaviors. OBJECTIVE: To explore student perceptions of challenges and opportunities when participating in implicit bias instruction. APPROACH: We conducted a qualitative study that involved 11 focus groups with medical students across each of the four class years to explore their perceptions of challenges and opportunities related to participating in such instruction. We analyzed transcripts for themes. KEY RESULTS: Our analysis suggests a range of attitudes toward implicit bias instruction and identifies contextual factors that may influence these attitudes. The themes were (1) resistance; (2) shame; (3) the negative role of the hidden curriculum; and (4) structural barriers to student engagement. Students expressed resistance to implicit bias instruction; some of these attitudes are fueled from concerns of anticipated shame within the learning environment. Participants also indicated that student engagement in implicit bias instruction was influenced by the hidden curriculum and structural barriers. CONCLUSIONS: These insights can inform future curriculum development efforts. Considerations related to instructional design and programmatic decision-making are highlighted. These considerations for implicit bias instruction may provide useful frameworks for educators looking for opportunities to minimize student resistance and maximize engagement in multi-session instruction in implicit bias recognition and management.

RESUMEN

BACKGROUND: One strategy to promote improved hand hygiene is to monitor health care workers' adherence to recommended practices and give feedback. For feasibility of monitoring, many health care facilities assess hand hygiene practices on room entry and exit (wash in-wash out). It is not known if the wash in-wash out method is comparable with a more comprehensive approach, such as the World Health Organization's My 5 Moments for Hand Hygiene method. METHODS: During a 1-month period, a surreptitious observer monitored hand hygiene compliance simultaneously using the wash in-wash out and My 5 Moments for Hand Hygiene methods. RESULTS: For 283 health care worker room entries, the methods resulted in similar rates of hand hygiene compliance (70% vs 72%, respectively). The wash in-wash out method required 148 hand hygiene events not required by the My 5 Moments for Hand Hygiene method (ie, before and after room entry with no patient or environmental contact) while not providing monitoring for 89 hand hygiene opportunities in patient rooms. CONCLUSION: The monitoring methods resulted in similar overall rates of hand hygiene compliance. Use of the wash in-wash out method should include ongoing education and intermittent assessment of hand hygiene before clean procedures and after body fluid exposure in patient rooms.

RESUMEN

OBJECTIVES: The objectives of this study were to develop a better understanding of which patients with chronic illness tend to respond to integrative medicine interventions, by identifying a set of characteristics or qualities that are associated with a positive outcome in a randomized clinical trial of an integrative medicine approach to asthma that incorporated journaling, yoga breathing instruction, and nutritional manipulation and supplementation. DESIGN: The study used qualitative analysis using a grounded-theory approach comparing a group of responders in the parent trial (based on the Asthma Quality of Life Scale) to a group of nonresponders. RESULTS: Twelve (12) responders and 8 nonresponders were interviewed. Responders demonstrated an attitude of "change as challenge;" a view of themselves as "independent" and "leaders;" an ability to accept one's illness while still maintaining a feeling of control over one's choices; a connection to the deeper context or meaning of complementary and alternative medicine (CAM) interventions, as opposed to just "previous experience" of CAM; and a sense of determination, commitment, and "willingness to fight" for what one needs from the health care system. Nonresponders were more often uncertain and anxious in their relationship to their asthma, tending to fall back on denial, and lacking a connection to the deeper context or philosophy of CAM interventions. CONCLUSIONS: It is possible to identify a set of characteristics that may predict a positive response to an integrative/lifestyle approach to asthma. These characteristics should be examined prospectively using both quantitative and qualitative methods in future integrative medicine clinical trials.
