Co-occurring implementation strategies: The effects of academic detailing for opioid use disorder campaign on the advancing pharmacological treatments for opioid use disorder (ADaPT-OUD) study.

Background: Barriers at the system, clinician, and patient level limit access to medications for opioid use disorder (MOUD). The Advancing Pharmacological Treatments for Opioid Use Disorder (ADaPT-OUD) study implemented an external facilitation strategy within the Veterans Health Administration (VHA) aimed at facility-level barriers to improve uptake of MOUD. During ADaPT-OUD, an independent Academic Detailing Services Opioid Agonist Treatment of OUD Campaign was co-occurring and aimed to increase evidence-based practice for OUD at the clinician level. While both these initiatives aim to increase MOUD reach, they address different barriers and did not intentionally collaborate. Thus, understanding the interaction between these two independent implementation initiatives and their effect on MOUD reach will further inform and mold future implementation efforts of MOUD. Methods: This was a secondary analysis of the ADaPT-OUD study that included 35 VHA facilities in the lowest quartile of MOUD reach; eight received the ADaPT-OUD external facilitation and 27 matched sites received implementation as usual. The number of academic detailing (AD) visits during ADaPT-OUD was used as a proxy for the intensity of Academic Detailing for OUD Campaign activity. The interaction between external facilitation status and AD intensity was evaluated by comparing the change in facility-level MOUD reach. Results: There was a general increase in the number of AD visits, in both external facilitation and implementation as usual sites, over the course of ADaPT-OUD's implementation period. A non-statistically significant, positively sloped, linear relationship was observed between average number of AD visits per quarter and change in MOUD reach in facilities also receiving ADaPT-OUD external facilitation that was not observed in the implementation as usual sites. Conclusion: Co-occurring initiatives focusing on different barriers to MOUD access have the potential to further increase MOUD in low-performing facilities, but further research into timing, quality, and collaboration between initiatives are warranted.

Medication treatment of opioid use disorder (MOUD) is a key element in addressing the opioid epidemic. The development, approval, and effectiveness of buprenorphine and naltrexone have expanded access to MOUD from specialty opioid treatment programs to office-based treatment. However, uptake of these evidence-based treatments across the Veterans Health Administration (VHA) is variable. To address this gap in care within the VHA, The Advancing Pharmacological Treatment for Opioid Use Disorder (ADaPT-OUD) study implemented an external facilitation strategy aimed at facility-level barriers at low-adopting VHA facilities while the VHA Pharmacy Benefits Management Academic Detailing Services Opioid Agonist Treatment of OUD Campaign implemented academic detailing with the goal to address clinician-level barriers. This article evaluates the effect these two co-occurring and independent initiatives had on each other and MOUD reach. The results suggest a trend toward a positive synergistic relationship between the two initiatives, that warrants further study and evaluation to inform further implementation efforts.

Implementation of Evidence-Based Psychotherapies for Posttraumatic Stress Disorder: A Systematic Review.

Guidelines strongly recommend trauma-focused therapies to treat posttraumatic stress disorder. Implementation of cognitive processing therapy (CPT) and prolonged exposure (PE) in Veterans Health Administration (VHA) and non-VHA settings began in 2006. We conducted a systematic review of implementation facilitators and challenges and strategies to address barriers. We searched MEDLINE, Embase, PsycINFO, and CINAHL from inception until March 2021 for English-language articles. Two individuals reviewed eligibility and rated quality. Quantitative results were abstracted by one reviewer and verified by a second. Qualitative results were independently coded by two reviewers and finalized through consensus. We used RE-AIM and CFIR frameworks to synthesize findings. 29 eligible studies addressed CPT/PE, mostly conducted in VHA. Training/education with audit/feedback was the primary implementation strategy and was linked to improved provider CPT/PE perceptions and self-efficacy. Use was not widespread. Only six studies tested other implementation strategies with mixed impact. Following VHA implementation, strong support for training, perceived effectiveness for patients and benefits for clinics, and positive patient experiences and relationships with providers were reported. However, barriers persisted including perceived protocol inflexibility, complex referral processes and patient complexity and competing needs. In non-VHA settings, providers perceived fewer barriers, but few were CPT/PE trained. Across both settings, fewer studies targeted patient factors. Training/education with audit/feedback improved perceptions and the availability of CPT/PE, but not consistent use. Studies testing implementation strategies to address post-training challenges, including patient-level factors, are needed. A few studies are underway in VHA to test patient-focused and other implementation strategies. Research assessing actual vs perceived barriers in non-VHA settings is needed to elucidate unique challenges experienced.

Barriers and Facilitators of Evidence-Based Psychotherapies for Chronic Pain in Adults: A Systematic Review.

Cognitive behavioral therapy (CBT), acceptance and commitment therapy (ACT), and mindfulness-based stress reduction (MBSR) have demonstrated effectiveness for improving outcomes in chronic pain. These evidence-based psychotherapies (EBPs) remain underutilized in clinical practice, however. To identify research gaps and next steps for improving uptake of EBPs, we conducted a systematic review of patient-, provider-, and system-level barriers and facilitators of their use for chronic pain. We searched MEDLINE, Embase, PsycINFO, and CINAHL databases from inception through September 2022. Prespecified eligibility criteria included outpatient treatment of adults with chronic pain; examination of barriers and facilitators and/or evaluation of implementation strategies; conducted in the United States (US), United Kingdom (UK), Ireland, Canada or Australia; and publication in English. Two reviewers independently assessed eligibility and rated quality. We conducted a qualitative synthesis of results using a best-fit framework approach building upon domains of the Consolidated Framework for Implementation Research (CFIR). We identified 34 eligible studies (33 moderate or high quality), most (n = 28) of which addressed patient-level factors. Shared barriers across EBPs included variable patient buy-in to therapy rationale and competing responsibilities for patients; shared facilitators included positive group or patient-therapist dynamics. Most studies examining ACT and all examining MBSR assessed only group formats. No studies compared barriers, facilitators, or implementation strategies of group CBT to individual CBT, or of telehealth to in-person EBPs. Conceptual mismatches of patient knowledge and beliefs with therapy principles were largely analyzed qualitatively, and studies did not explore how these mismatches were addressed to support engagement. Future research on EBPs for chronic pain in real-world practice settings is needed to explore provider and system-level barriers and facilitators, heterogeneity of effects and uptake, and both effects and uptake of EBPs delivered in various formats, including group vs individual therapy and telehealth or asynchronous digital approaches. PERSPECTIVE: This systematic review synthesizes evidence on barriers and facilitators to uptake of cognitive behavioral therapy, acceptance and commitment therapy, and mindfulness-based stress reduction for chronic pain. Findings can guide future implementation work to increase availability and use of evidence-based psychotherapies for treatment of chronic pain. REGISTRATION: PROSPERO number CRD42021252038.

PPARγ-Mediated p21 Induction in Aerodigestive Preneoplastic Cell Lines.

INTRODUCTION: Oral leukoplakia is defined as a mucous membrane disorder characterized by white patches that cannot be scraped off. Leukoplakia is the most frequent, potentially premalignant oral mucosa disorder and a good candidate for chemopreventive therapies. Pioglitazone activates peroxisome proliferator-activated receptor gamma (PPARγ), which forms a complex with nuclear cofactors and regulates gene expression of a variety of cell-cycle proteins and is currently being tested preclinically and clinically in aerodigestive cancer prevention. METHODS: In the present study, we hypothesized that pioglitazone would decrease proliferation of human leukoplakia cells (MSK Leuk1) and transformed bronchial epithelial cells (BEAS-2B) through regulatory changes of G1 checkpoint protein regulators, p21 and cyclin-D1. MSK Leuk1 and BEAS-2B cells were treated with pioglitazone and assayed for cell proliferation and p21 transcriptional activity. RESULTS: We discovered pioglitazone significantly inhibited cell proliferation in a dose-dependent fashion. We also observed p21 protein induction after treatment with pioglitazone, which was preceded by measurable increases in p21 mRNA induction. CONCLUSIONS: We conclude the PPARγ activator, pioglitazone, can activate p21, which is associated with decreased proliferation in 2 aerodigestive preneoplastic cell lines. In addition, the p21 gene may be a potential hypothesis-driven biomarker in translational studies of pioglitazone as a chemoprevention agent for aerodigestive cancer.

Fixed-Dose Combinations of Pioglitazone and Metformin for Lung Cancer Prevention.

Combination treatment with pioglitazone and metformin is utilized clinically in the treatment of type II diabetes. Treatment with this drug combination reduced the development of aerodigestive cancers in this patient population. Our goal is to expand this treatment into clinical lung cancer chemoprevention. We hypothesized that dietary delivery of metformin/pioglitazone would prevent lung adenoma formation in A/J mice in a benzo[a]pyrene (B[a]P)-induced carcinogenesis model while modulating chemoprevention and anti-inflammatory biomarkers in residual adenomas. We found that metformin (500 and 850 mg/kg/d) and pioglitazone (15 mg/kg/d) produced statistically significant decreases in lung adenoma formation both as single-agent treatments and in combination, compared with untreated controls, after 15 weeks. Treatment with metformin alone and in combination with pioglitazone resulted in statistically significant decreases in lung adenoma formation at both early- and late-stage interventions. Pioglitazone alone resulted in significant decreases in adenoma formation only at early treatment intervention. We conclude that oral metformin is a viable chemopreventive treatment at doses ranging from 500 to 1,000 mg/kg/d. Pioglitazone at 15 mg/kg/d is a viable chemopreventive agent at early-stage interventions. Combination metformin and pioglitazone performed equal to metformin alone and better than pioglitazone at 15 mg/kg/d. Because the drugs are already FDA-approved, rapid movement to human clinical studies is possible. Cancer Prev Res; 10(2); 116-23. ©2017 AACR.

Functional activation of PPARγ in human upper aerodigestive cancer cell lines.

Upper aerodigestive cancer is an aggressive malignancy with relatively stagnant long-term survival rates over 20 yr. Recent studies have demonstrated that exploitation of PPARγ pathways may be a novel therapy for cancer and its prevention. We tested whether PPARγ is expressed and inducible in aerodigestive carcinoma cells and whether it is present in human upper aerodigestive tumors. Human oral cancer CA-9-22 and NA cell lines were treated with the PPAR activators eicosatetraynoic acid (ETYA), 15-deoxy-δ- 12,14-prostaglandin J2 (PG-J2), and the thiazolidinedione, ciglitazone, and evaluated for their ability to functionally activate PPARγ luciferase reporter gene constructs. Cellular proliferation and clonogenic potential after PPARγ ligand treatment were also evaluated. Aerodigestive cancer specimens and normal tissues were evaluated for PPARγ expression on gene expression profiling and immunoblotting. Functional activation of PPARγ reporter gene constructs and increases in PPARγ protein were confirmed in the nuclear compartment after PPARγ ligand treatment. Significant decreases in cell proliferation and clonogenic potential resulted from treatment. Lipid accumulation was induced by PPARγ activator treatment. 75% of tumor specimens and 100% of normal control tissues expressed PPARγ RNA, and PPARγ protein was confirmed in 66% of tumor specimens analyzed by immunoblotting. We conclude PPARγ can be functionally activated in upper aerodigestive cancer and that its activation downregulates several features of the neoplastic phenotype. PPARγ expression in human upper aerodigestive tract tumors and normal cells potentially legitimizes it as a novel intervention target in this disease. © 2016 Wiley Periodicals, Inc.

Safety and Preclinical Efficacy of Aerosol Pioglitazone on Lung Adenoma Prevention in A/J Mice.

Pioglitazone is a PPARγ agonist commonly prescribed for the clinical treatment of diabetes. We sought to expand its use to lung cancer prevention in a benzo[a]pyrene (B[a]P) mouse model with direct lung delivery via inhalation. Initially, we conducted inhalational toxicity experiments with 0, 15, 50, 150, and 450 µg/kg body weight/day pioglitazone in 40 A/J mice. We examined the animals for any physical toxicity and bronchoalveolar lavage fluids for inflammatory and cytotoxicity markers. Doses up to and including 450 µg/kg bw/d failed to demonstrate toxicity with aerosol pioglitazone. For chemoprevention experiments, A/J mice were randomized to treatment groups of inhaled doses of 0, 50, 150, or 450 µg/kg bw/d pioglitazone 1 or 8 weeks after the last dose of B[a]P. For the early treatment group, we found up to 32% decrease in lung adenoma formation with 450 µg/kg bw/d pioglitazone. We repeated the treatments in a second late-stage experiment and found up to 44% decreases in lung adenoma formation in doses of pioglitazone of 150 and 450 µg/kg bw/day. Both the early- and the late-stage experiments demonstrated biologically relevant and statistically significant decreases in adenoma formation. We conclude that aerosol pioglitazone is well-tolerated in the A/J mouse model and a promising chemoprevention agent for the lower respiratory tract. Cancer Prev Res; 10(2); 124-32. ©2016 AACR.

Breastfeeding practice lab: a new approach to telenurse education.

Breastfeeding inquiries represent a significant number of calls to HealthLink BC (HLBC). As Telenurses have indicated a great deal of uncertainty and a degree of disparity in practice, findings from previous research revealed a need to expand Telenurse breastfeeding education and a need for a new education delivery approach. This paper will describe the new education approach, an approach that included development of a practice lab framework and development of the first activity based on this framework - The Breastfeeding Practice Labs. The labs were set-up with six different 30 minute stations designed for independent or group learning, and created to stimulate critical thinking. Each lab was three hours and could also easily accommodate "drop-ins". The goal of the Breastfeeding Practice Labs was to enhance Telenurse knowledge, skills, and confidence for assessing breastfeeding calls. Post evaluation results of the pilot labs revealed positive shifts in Telenurse confidence for assessing breastfeeding calls.

Attitudes of US medical trainees towards neurology education: "Neurophobia" - a global issue.

BACKGROUND: Several studies in the United Kingdom and Asia have suggested that medical students and residents have particular difficulty in diagnosing and managing patients with neurological problems. Little recent information is available for US trainees. We examined whether students and residents at a US university have difficulty in dealing with patients with neurological problems, identified the perceived sources of these difficulties and provide suggestions for the development of an effective educational experience in neurology. METHODS: A questionnaire was administered to third and fourth year medical students at a US school of medicine and to residents of an internal medicine residency program affiliated with that school. Perceived difficulties with eight medical specialties, including neurology, were examined. Methods considered to be most useful for learning medicine were documented. Reasons why neurology is perceived as difficult and ways to improve neurological teaching were assessed. RESULTS: 152 surveys were completed. Participation rates varied, with medical students having higher response rates (> 50%) than medical residents (27%-48%). Respondents felt that neurology was the medical specialty they had least knowledge in (p < 0.001) and was most difficult (p < 0.001). Trainees also felt they had the least confidence when dealing with patients with neurological complaints (p < 0.001). Residents felt more competent in neurology than students (p < 0.001). The paramount reasons for perceived difficulties with neurology were the complexity of neuroanatomy, limited patient exposure and insufficient teaching. Transition from pre-clinical to clinical medicine led to a doubling of "poor" ratings for neurological teaching. Over 80% of the respondents felt that neurology teaching could be improved through greater exposure to patients and more bedside tutorials. CONCLUSIONS: Medical students and residents at this US medical university found neurology difficult. Although this is consistent with prior reports from Europe and Asia, studies in other universities are needed to confirm generalizability of these findings. The optimal opportunity for improvement is during the transition from preclinical to clinical years. Enhanced integration of basic neurosciences and clinical neurology with emphasis on increased bedside tutorials and patient exposure should improve teaching. Studies are needed to quantify the effect of these interventions on confidence of trainees when dealing with patients presenting with neurological complaints.

Acute variation in cognitive function in hemodialysis patients: a cohort study with repeated measures.

BACKGROUND: Although cognitive function in hemodialysis patients is believed to be best 24 hours after the dialysis session, the extent of variation during the dialysis cycle is unknown. STUDY DESIGN: Cohort study with repeated measures. SETTING & PARTICIPANTS: Hemodialysis centers; patients aged 55 years or older. PREDICTOR: Time of assessment related to the dialysis session. Time 1 (T1) occurred approximately 1 hour before the dialysis session; T2, 1 hour into the session; T3, 1 hour after; and T4, the next day. OUTCOMES: Measures of cognitive function using a 45-minute cognitive battery. An average composite score was calculated to measure global cognitive function, equal to the average of subjects' standardized scores on all tests given at each test time. Times were classified as best and worst according to composite scores. MEASUREMENTS: Testing was conducted on average over 2 dialysis sessions to avoid test fatigue. The cognitive battery included tests of verbal fluency, immediate and delayed verbal and visual memory, and executive function, administered at 4 times. RESULTS: In the 28 subjects who completed testing at 3 or 4 testing times, mean age was 66.7 +/- 9.5 years and mean dialysis vintage was 44.7 +/- 33.3 months. Using a general linear model for correlated data, the composite score was significantly lower (poorer) during dialysis (T2) than shortly before the session (T1) or on the next day (T4; P < 0.001 for both). LIMITATIONS: Relatively small sample size, testing delays, results may not be generalizable. CONCLUSION: Global cognitive function varies significantly during the dialysis cycle, being worst during dialysis and best shortly before the session or on the day after. Clinician visits may be most effective at these times.
