The American Society of Addiction Medicine Clinical Practice Guideline Development Methodology.

ABSTRACT: The American Society of Addiction Medicine (ASAM) has published clinical practice guidelines (CPGs) since 2015. As ASAM's CPG work continues to develop, it maintains an organizational priority to establish rigorous standards for the trustworthy production of these important documents. In keeping with ASAM's mission to define and promote evidence-based best practices in addiction prevention, treatment, and recovery, ASAM has rigorously updated its CPG methodology to be in line with evolving international standards. The CPG Methodology and Oversight Subcommittee was formed to establish and publish a methodology for the development of ASAM CPGs and to develop an ASAM CPG strategic plan. This article provides a focused overview of the ASAM CPG methodology.

Cannabis Use in Pregnancy and Neonatal Outcomes: A Systematic Review and Meta-Analysis.

Objective: To determine whether prenatal cannabis use alone increases the likelihood of fetal and neonatal morbidity and mortality. Study Design: We searched bibliographic databases, such as PubMed, Embase, Scopus, Cochrane reviews, PsycInfo, MEDLINE, Clinicaltrials.gov, and Google Scholar from inception through February 14, 2022. Cohort or case-control studies with prespecified fetal or neonatal outcomes in pregnancies with prenatal cannabis use. Primary outcomes were preterm birth (PTB; <37 weeks of gestation), small-for-gestational-age (SGA), birthweight (grams), and perinatal mortality. Two independent reviewers screened studies. Studies were extracted by one reviewer and confirmed by a second using a predefined template. Risk of bias assessment of studies, using the Newcastle-Ottawa Quality Assessment Scale, and Grading of Recommendations Assessment, Development, and Evaluation for evaluating the certainty of evidence for select outcomes were performed by two independent reviewers with disagreements resolved by a third. Random effects meta-analyses were conducted, using adjusted and unadjusted effect estimates, to compare groups according to prenatal exposure to cannabis use status. Results: Fifty-three studies were included. Except for birthweight, unadjusted and adjusted meta-analyses had similar results. We found very-low- to low-certainty evidence that cannabis use during pregnancy was significantly associated with greater odds of PTB (adjusted odds ratio [aOR], 1.42; 95% confidence interval [CI], 1.19 to 1.69; I2, 93%; p=0.0001), SGA (aOR, 1.76; 95% CI, 1.52 to 2.05; I2, 86%; p<0.0001), and perinatal mortality (aOR, 1.5; 95% CI, 1.39 to 1.62; I2, 0%; p<0.0001), but not significantly different for birthweight (mean difference, -40.69 g; 95% CI, -124.22 to 42.83; I2, 85%; p=0.29). Because of substantial heterogeneity, we also conducted a narrative synthesis and found comparable results to meta-analyses. Conclusion: Prenatal cannabis use was associated with greater odds of PTB, SGA, and perinatal mortality even after accounting for prenatal tobacco use. However, our confidence in these findings is limited. Limitations of most existing studies was the failure to not include timing or quantity of cannabis use. This review can help guide health care providers with counseling, management, and addressing the limited existing safety data. Protocol Registration: PROSPERO CRD42020172343.

Ambulatory Intensive Care for Medically Complex Patients at a Health Care Clinic for Individuals Experiencing Homelessness: The SUMMIT Randomized Clinical Trial.

Importance: Intensive primary care interventions have been promoted to reduce hospitalization rates and improve health outcomes for medically complex patients, but evidence of their efficacy is limited. Objective: To assess the efficacy of a multidisciplinary ambulatory intensive care unit (A-ICU) intervention on health care utilization and patient-reported outcomes. Design, Setting, and Participants: The Streamlined Unified Meaningfully Managed Interdisciplinary Team (SUMMIT) randomized clinical trial used a wait-list control design and was conducted at a health care clinic for patients experiencing homelessness in Portland, Oregon. The first patient was enrolled in August 2016, and the last patient was enrolled in November 2019. Included patients had 1 or more hospitalizations in the prior 6 months and 2 or more chronic medical conditions, substance use disorder, or mental illness. Data analysis was performed between March and May 2021. Intervention: The A-ICU included a team manager, a pharmacist, a nurse, care coordinators, social workers, and physicians. Activities included comprehensive 90-minute intake, transitional care coordination, and flexible appointments, with reduced panel size. Enhanced usual care (EUC), consisting of team-based primary care with access to community health workers and mental health, addiction treatment, and pharmacy services, served as the comparator. Participants who received EUC joined the A-ICU intervention after 6 months. Main Outcomes and Measures: The main outcome was the difference in rates of hospitalization (primary outcome), emergency department (ED) visits, and primary care physician (PCP) visits per person over 6 months (vs the prior 6 months). Patient-reported outcomes included changes in patient activation, experience, health-related quality of life, and self-rated health at 6 months (vs baseline). We performed an intention-to-treat analysis using a linear mixed-effects model with a random intercept for each patient to examine the association between study group and outcomes. Results: This study randomized 159 participants (mean [SD] age, 54.9 [9.8] years) to the A-ICU SUMMIT intervention (n = 80) or to EUC (n = 79). The majority of participants were men (102 [65.8%]) and most were White (121 [76.1%]). A total of 64 participants (41.0%) reported having unstable housing at baseline. Six-month hospitalizations decreased in both the A-ICU and EUC groups, with no difference between them (mean [SE], -0.6 [0.5] vs -0.9 [0.5]; difference, 0.3 [95% CI, -1.0 to 1.5]). Emergency department use did not differ between groups (mean [SE], -2.0 [1.0] vs 0.9 [1.0] visits per person; difference, -1.1 [95% CI, -3.7 to 1.6]). Primary care physician visits increased in the A-ICU group (mean [SE], 4.2 [1.6] vs -2.0 [1.6] per person; difference, 6.1 [95% CI, 1.8 to 10.4]). Patients in the A-ICU group reported improved social functioning (mean [SE], 4.7 [2.0] vs -1.1 [2.0]; difference, 5.8 [95% CI, 0.3 to 11.2]) and self-rated health (mean [SE], 0.7 [0.3] vs -0.2 [0.3]; difference, 1.0 [95% CI, 0.1 to 1.8]) compared with patients in the EUC group. No differences in patient activation or experience were observed. Conclusions and Relevance: The A-ICU intervention did not change hospital or ED utilization at 6 months but increased PCP visits and improved patient well-being. Longer-term studies are needed to evaluate whether these observed improvements lead to eventual changes in acute care utilization. Trial Registration: ClinicalTrials.gov Identifier: NCT03224858.

Dispensary Staff Perceptions About the Benefits, Risks, and Safety of Cannabis for Medical Purposes.

BACKGROUND: Therapeutic use of cannabis is common in the United States (up to 18.7% of Americans aged ≥12), and dispensaries in the US are proliferating rapidly. However, the efficacy profile of medical cannabis is unclear, and customers often rely on dispensary staff for purchasing decisions. The objective was to describe cannabis dispensary staff perceptions of medical cannabis benefits and risks, as well as its safety in high-risk populations. METHODS: Online Survey study conducted using Qualtrics from February 13, 2020 to October 2, 2020 with a national sample of dispensary staff who reportedinteracting with customers in a cannabis dispensary selling tetrahydrocannabinol-containing products. Participants were queried about benefits ("helpfulness") and risks ("worry") about cannabis for a variety of medical conditions, and safety in older adults and pregnant women on a five-point Likert scale. These results were then collapsed into three categories including "neutral" (3/5). "I don't know" (uncertainty) was a response option for helpfulness and safety. RESULTS: Participants (n = 434) were from 29 states and included patient-facing dispensary staff (40%); managers (32%); pharmacists (13%); and physicians, nurse practitioners, or physician assistants (5%). Over 80% of participants perceived cannabis as helpful for post-traumatic stress disorder (88.7%), epilepsy (85.3%) and cancer (83.4%). Generally, participants were not concerned about potential cannabis risks, including increased use of illicit drugs (76.3%), decreases in intelligence (74.4%), disrupted sleep (71.7%), and new/worsening health problems from medical cannabis use (70.7%). Cannabis was considered safe in older adults by 81.3% of participants, though there was much less consensus on safety in pregnancy. CONCLUSIONS: Cannabis dispensary staff generally view medical cannabis as beneficial and low-risk. However, improvements in dispensary staff training, an increased role for certifying clinicians, and interventions to reduce dispensary staff concerns (e.g., cost, judgment) may improve evidence-based staff recommendations to patients seeking medical cannabis.

Cannabis dispensary staff approaches to counseling on potential contraindications to cannabis use: insights from a national self-report survey.

BACKGROUND: Legal cannabis is available in more than half of the United States. Health care professionals (HCPs) rarely give recommendations on dosing or safety of cannabis due to limits imposed by policy and lack of knowledge. Customer-facing cannabis dispensary staff, including clinicians (pharmacists, nurses, physician's assistants), communicate these recommendations in the absence of HCP recommendations. Little is known about how dispensary staff approach individuals with complex medical and psychiatric comorbidities. Using responses from a national survey, we describe how cannabis dispensary staff counsel customers with medical and psychiatric comorbidities on cannabis use and examine whether state-specific cannabis policy is associated with advice given to customers. METHODS: National, cross-sectional online survey study from February 13, 2020 to October 2, 2020 of dispensary staff at dispensaries that sell delta-9-tetrahydrocannabinol containing products. Measures include responses to survey questions about how they approach customers with medical and psychiatric comorbidities; state medicalization score (scale 0-100; higher score indicates more similarity to regulation of traditional pharmacies); legalized adult-use cannabis (yes/no). We conducted multiple mixed effects multivariable logistic regression analyses to understand relationships between state medicalization and dispensary employees' perspectives. RESULTS: Of 434 eligible respondents, most were budtenders (40%) or managers (32%), and a minority were clinicians (18%). State medicalization score was not associated with responses to most survey questions. It was associated with increased odds of encouraging customers with medical comorbidities to inform their traditional HCP of cannabis use (Odds ratio [OR]=1.2, 95% confidence interval [CI] 1.0-1.4, p=0.03) and reduced odds of recommending cannabis for individuals with cannabis use disorder (CUD) (OR=0.8, 95% CI 0.7-1.0, p=0.04). Working in a state with legalized adult-use cannabis was associated with recommending traditional health care instead of cannabis in those with serious mental illness (OR 2.2, 95% CI 1.1-4.7, p=0.04). Less than half of respondents believed they had encountered CUD (49%), and over a quarter did not believe cannabis is addictive (26%). CONCLUSIONS: When managing cannabis dosing and safety in customers with medical and psychiatric comorbidity, dispensary staff preferred involving individuals' traditional HCPs. Dispensary staff were skeptical of cannabis being addictive. While state regulations of dispensaries may impact the products individuals have access to, they were not associated with recommendations that dispensary staff gave to customers. Alternative explanations for dispensary recommendations may include regional or store-level variation not captured in this analysis.

Effectiveness and Safety of Treatments to Prevent Fractures in People With Low Bone Mass or Primary Osteoporosis: A Living Systematic Review and Network Meta-analysis for the American College of Physicians.

BACKGROUND: The prevalence of osteoporosis is increasing in the United States. PURPOSE: To evaluate low bone mass and osteoporosis treatments to prevent fractures. DATA SOURCES: Ovid MEDLINE ALL, Ovid Evidence Based Medicine Reviews: Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and ClinicalTrials.gov from 2014 through February 2022. STUDY SELECTION: Adults receiving eligible interventions for low bone mass or osteoporosis. Randomized controlled trials (RCTs) for fracture outcomes, and RCTs and large observational studies (n ≥1000) for harms. DATA EXTRACTION: Abstracted by 1 reviewer and verified by a second. Independent, dual assessments of risk of bias and certainty of evidence (CoE). DATA SYNTHESIS: We included 34 RCTs (in 100 publications) and 36 observational studies. Bisphosphonates and denosumab reduced hip, clinical and radiographic vertebral, and other clinical fractures in postmenopausal females with osteoporosis (moderate to high CoE). Bisphosphonates for 36 months or more may increase the risk for atypical femoral fractures (AFFs) and osteonecrosis of the jaw (ONJ), but the absolute risks were low. Abaloparatide and teriparatide reduced clinical and radiographic vertebral fractures but increased the risk for withdrawals due to adverse events (WAEs; moderate to high CoE). Raloxifene and bazedoxifene for 36 months or more reduced radiographic vertebral but not clinical fractures (low to moderate CoE). Abaloparatide, teriparatide, and sequential romosozumab, then alendronate, may be more effective than bisphosphonates in reducing clinical fractures for 17 to 24 months in older postmenopausal females at very high fracture risk (low to moderate CoE). Bisphosphonates may reduce clinical fractures in older females with low bone mass (low CoE) and radiographic vertebral fractures in males with osteoporosis (low to moderate CoE). LIMITATION: Few studies examined participants with low bone mass, males, or Black-identifying persons, sequential therapy, or treatment beyond 3 years. CONCLUSION: Bisphosphonates, denosumab, abaloparatide, teriparatide, and romosozumab, followed by alendronate, reduce clinical fractures in postmenopausal females with osteoporosis. Abaloparatide and teriparatide increased WAEs; longer duration bisphosphonate use may increase AFF and ONJ risk though these events were rare. PRIMARY FUNDING SOURCE: American College of Physicians.

Trends in Robot-Assisted Procedures for General Surgery in the Veterans Health Administration.

INTRODUCTION: Implementation of robot-assisted procedures is growing. Utilization within the country's largest healthcare network, the Veterans Health Administration, is unclear. METHODS: A retrospective cohort study using data from the Department of Veterans Affairs Corporate Data Warehouse from January 2015 through December 2019. Trends in robot utilization for cholecystectomy, ventral hernia repair, and inguinal hernia repair were characterized nationally and regionally by Veterans Integrated Services Network. Patients, who underwent laparoscopic repairs for these procedures and open hernia repairs, were included to determine proportion performed robotically. RESULTS: We identified 119,191 patients, of which 5689 (4.77%) received a robotic operation. The proportion of operations performed robotically increased from 1.49% to 10.55% (7.08-fold change; slope, 2.14% per year; 95% confidence interval [0.79%, 3.49%]). Ventral hernia repair had the largest growth in robotic procedures (1.51% to 13.94%; 9.23-fold change; slope, 2.86% per year; 95% confidence interval [1.04%, 4.68%]). Regions with the largest increase in robotic utilization were primarily along the Northeast, Midwest, and West Coast. CONCLUSIONS: Robot utilization in general surgery is increasing at different rates across the United States in the Veterans Health Administration. Future studies should investigate the regional disparities and drivers of this approach.

Robot-Assisted General Surgery Procedures at the Veterans Health Administration: A Comparison of Surgical Techniques.

INTRODUCTION: The use of the robot in general surgery has exploded in the last decade. The Veterans Health Administration presents a unique opportunity to study differences between surgical approaches due to the ability to control for health system and insurance variability. This study compares clinical outcomes between robot-assisted and laparoscopic or open techniques for three general surgery procedures. METHODS: A retrospective observational study using the Veterans Affair Surgical Quality Improvement Program database. Operative time, length of stay, and complications were compared for cholecystectomy (robot-assisted versus laparoscopic), ventral, and inguinal hernia repair (robot-assisted versus laparoscopic or open) from 2015 to 2019. RESULTS: More than 80,000 cases were analyzed (21,652 cholecystectomy, 9214 ventral hernia repairs, and 51,324 inguinal hernia repairs). Median operative time was longer for all robot-assisted approaches as compared to laparoscopic or open techniques with the largest difference seen between open and robot-assisted primary ventral hernia repair (unadjusted difference of 93 min, P < 0.001). Median length of stay was between 1 and 4 d and significantly for robot-assisted ventral hernia repairs (versus open, P < 0.01; versus lap for recurrent hernia, P < 0.05). Specific postoperative outcomes of interest were overall low with few differences between techniques. CONCLUSIONS: While the robotic platform was associated with longer operative time, these findings must be interpreted in the context of a learning curve and indications for use (i.e., use of the robot for technically challenging cases). Our findings suggest that at the Veterans Health Administration, the robot is as safe a platform for common general surgery procedures as traditional approaches. Future studies should focus on patient-centered outcomes including pain and cosmesis.

Expanding access to medications for opioid use disorder through locally-initiated implementation.

BACKGROUND: Despite demonstrated efficacy, medication treatment for opioid use disorder (MOUD) remain inaccessible to many patients, with barriers identified at the individual, clinic and system level. A wide array of implementation strategies have guided efforts to expand access to MOUD, with most centered around externally-facilitated approaches to practice change. While effective, such approaches may be inaccessible to those clinics and systems that lack the resources necessary to partner with an external team, suggesting a need to identify and describe change-processes that are internally developed and promoted. METHODS: Guided by the Consolidated Framework for Implementation Research (CFIR), we utilized qualitative interviews and ethnographic observation to investigate the planning, design and implementation of a locally-initiated process to expand access to MOUD within one health care system. All study documents were coded by a primary coder and secondary reviewer using a codebook designed for use with the CFIR. To analyze data, we reviewed text tagged by key codes, compared these textual excerpts both across and within documents, and organized findings into themes. Processes identified were mapped to established implementation science constructs and strategies. RESULTS: Interviews with clinicians and administrators (n = 9) and ethnographic observation of planning meetings (n = 3) revealed how a self-appointed local team developed, established broad support for, and successfully implemented a Primary Care-based Buprenorphine Clinic and E-Consult Service to expand access to MOUD to patients across the health care system. First, national and local policy changes-including altered clinical practice guidelines, performance pay incentives regarding opioid prescribing, and a directive from VA Central Office increased individual staff and administrators' perception of the need for change and willingness to invest time and resources. Then, a self-appointed interdisciplinary team utilized cross-clinic meetings and information gathering to identify appropriate, and widely supported, models of care delivery and care consultation. Finally, the team increased staff investment in these change efforts by bringing them into the planning process and encouraging collaborative problem solving. CONCLUSIONS: This study reveals how a local team developed and built widespread support for new processes of care that were tailored to local needs and well-positioned for sustainability over time.

Cannabis-Based Products for Chronic Pain : A Systematic Review.

BACKGROUND: Contemporary data are needed about the utility of cannabinoids in chronic pain. PURPOSE: To evaluate the benefits and harms of cannabinoids for chronic pain. DATA SOURCES: Ovid MEDLINE, PsycINFO, EMBASE, the Cochrane Library, and Scopus to January 2022. STUDY SELECTION: English-language, randomized, placebo-controlled trials and cohort studies (≥1 month duration) of cannabinoids for chronic pain. DATA EXTRACTION: Data abstraction, risk of bias, and strength of evidence assessments were dually reviewed. Cannabinoids were categorized by THC-to-CBD ratio (high, comparable, or low) and source (synthetic, extract or purified, or whole plant). DATA SYNTHESIS: Eighteen randomized, placebo-controlled trials (n = 1740) and 7 cohort studies (n = 13 095) assessed cannabinoids. Studies were primarily short term (1 to 6 months); 56% enrolled patients with neuropathic pain, with 3% to 89% female patients. Synthetic products with high THC-to-CBD ratios (>98% THC) may be associated with moderate improvement in pain severity and response (≥30% improvement) and an increased risk for sedation and are probably associated with a large increased risk for dizziness. Extracted products with high THC-to-CBD ratios (range, 3:1 to 47:1) may be associated with large increased risk for study withdrawal due to adverse events and dizziness. Sublingual spray with comparable THC-to-CBD ratio (1.1:1) probably is associated with small improvement in pain severity and overall function and may be associated with large increased risk for dizziness and sedation and moderate increased risk for nausea. Evidence for other products and outcomes, including longer-term harms, were not reported or were insufficient. LIMITATION: Variation in interventions; lack of study details, including unclear availability in the United States; and inadequate evidence for some products. CONCLUSION: Oral, synthetic cannabis products with high THC-to-CBD ratios and sublingual, extracted cannabis products with comparable THC-to-CBD ratios may be associated with short-term improvements in chronic pain and increased risk for dizziness and sedation. Studies are needed on long-term outcomes and further evaluation of product formulation effects.

Factors Associated with Health Inequalities in Infectious Disease Pandemics Predating COVID-19 in the United States: A Systematic Review.

Objective: Previous pandemics may offer evidence on mediating factors that contributed to disparities in infection and poor outcomes, which could inform the effort to mitigate potential unequal outcomes during the current COVID-19 pandemic. This systematic review sought to examine those factors. Methods: We searched MEDLINE, PsycINFO, and Cochrane to May 2020. We included studies examining health disparities in adult U.S. populations during infectious disease epidemics or pandemics. Two investigators screened abstracts and full text. We assessed study quality using the Newcastle/Ottawa Scale or the Critical Appraisal Skills Programme Checklist for Qualitative Studies. Results: Sixteen articles were included, of which 14 focused on health disparities during the 2009 H1N1 influenza pandemic. Studies showed that disparities during the H1N1 pandemic were more related to differential exposure to the virus than to susceptibility or access to care. Overall, pandemic-related disparities emanate primarily from inequalities in social conditions that place racial and ethnic minorities and low socioeconomic status populations at greater risk of exposure and infection, rather than individual-level factors such as health behaviors and comorbidities. Conclusions: Policy- and systems-level interventions should acknowledge and address these social determinants of heightened risk, and future research should evaluate the effects of such interventions to avoid further exacerbation of health inequities during the current and future pandemics.

What Is the Antibody Response and Role in Conferring Natural Immunity After SARS-CoV-2 Infection? Rapid, Living Practice Points From the American College of Physicians (Version 2).

DESCRIPTION: The Scientific Medical Policy Committee (SMPC) of the American College of Physicians (ACP) developed these living, rapid practice points to summarize the current best available evidence on the antibody response to SARS-CoV-2 infection and protection against reinfection with SARS-CoV-2. This is version 2 of the ACP practice points, which serves to update version 1, published on 16 March 2021. These practice points do not evaluate vaccine-acquired immunity or cellular immunity. METHODS: The SMPC developed this version of the living, rapid practice points based on an updated living, rapid, systematic review conducted by the Portland VA Research Foundation and funded by the Agency for Healthcare Research and Quality. PRACTICE POINT 1: Do not use SARS-CoV-2 antibody tests for the diagnosis of SARS-CoV-2 infection. PRACTICE POINT 2: Do not use SARS-CoV-2 antibody tests to predict the degree or duration of natural immunity conferred by antibodies against reinfection, including natural immunity against different variants. RETIREMENT FROM LIVING STATUS: Although natural immunity remains a topic of scientific interest, this topic is being retired from living status given the availability of effective vaccines for SARS-CoV-2 and widespread recommendations for and prevalence of their use. Currently, vaccination is the best clinical recommendation for preventing infection, reinfection, and serious illness from SARS-CoV-2 and its variants.

"The SUMMIT Team is All I Got": perspectives of medically and socially complex patients seen in intensive primary care.

Context: There is great interest in intensive primary care (IPC) interventions to address the needs of medically and socially complex patients, however it is unknown how these interventions impact patient experience. Objective: Describe the experience of patients on the Streamlined Unified Meaningfully Managed Interdisciplinary Team (SUMMIT), an IPC for patients with complex needs at a federally qualified health center serving patients with high rates of homelessness. Study Design: Qualitative study using semi-structured interviews with 25 patients enrolled in the SUMMIT intervention. We conducted a thematic analysis using a hybrid inductive/deductive approach. Results: Prior to SUMMIT, patients often felt it was difficult to engage with the healthcare system, in part due to their complex medical conditions, but also factors including prior trauma, poverty, substance use, and providers' stigma. We identified four themes related to how and why patients felt SUMMIT improved their care: 1) Investment: Patients perceived the team as truly invested in them and expressed how the team walked side by side in their care journeys to overcome stigma, low-self efficacy, and prior negative experiences with the healthcare system 2) Family: Patients reported feeling a strong sense of family with SUMMIT team members and believed that the team had genuine duty and obligation toward them, interacting with them in a non-judgmental, culturally competent manner. 3) Feeling valued: Patients expressed that the team's flexible design, continuity of team membership, care coordination and addressing unmet needs and social determinants led them to feel valued and hope. 4) Evolution of self-efficacy: Patients experienced improved self-efficacy, and were able to engage with health care proactively, instead of avoiding care. Conclusion: Medically and socially complex patients experience trauma and stigma that shape perceptions of care. Patients appreciated humanizing interactions with team members along with the additional support SUMMIT provided to overcome barriers to care. They spoke of the team as family members who valued them and they recognized how the program had helped them take a more active role in improving their own health. Our findings suggest that effectiveness of IPC interventions may lie, in part, on the use of team members who have the skills and commitment to deliver non-judgemental, culturally competent, longitudinal relationship-focused care.

Adjunct interventions to standard medical management of buprenorphine in outpatient settings: A systematic review of the evidence.

BACKGROUND: A growing body of research has examined adjunctive interventions supportive of engagement and retention in treatment among patients receiving buprenorphine for opioid use disorder (OUD). We conducted a systematic review of the literature addressing the effect on key outcomes of adjunctive interventions provided alongside standard medical management of buprenorphine in outpatient settings. METHODS: We included prospective studies examining adults receiving buprenorphine paired with an adjunctive intervention for the treatment of OUD in an outpatient setting. Data sources included Medline, Cochrane Central Register of Controlled Trials, CINAHL and PsycINFO from inception through January 2020. Two raters independently reviewed full-text articles, abstracted data and appraised risk of bias. Outcomes examined included abstinence, retention in treatment and non-addiction-related health outcomes. RESULTS: The final review includes 20 manuscripts, 11 randomized control trials (RCTs), three secondary analyses of RCTs and six observational studies. Most studies examined psychosocial interventions (n = 14). Few examined complementary therapies (e.g., yoga; n = 2) or technological interventions (e.g., electronic pill dispensation; n = 3); one study examined an intervention addressing structural barriers to care (patient navigators; n = 1). Low risk of bias RCTs found no evidence that adding psychosocial interventions to buprenorphine treatment improves substance use outcomes. CONCLUSIONS: Research is needed to identify adjunctive interventions with potential to support medication adherence and addiction-related outcomes for patients engaged in buprenorphine treatment. Data from clinical trials suggest that lack of ready access to psychosocial treatments should not discourage clinicians from prescribing buprenorphine.

Analysis of State Cannabis Laws and Dispensary Staff Recommendations to Adults Purchasing Medical Cannabis.

Importance: Over the last decade, cannabis has become more accessible through the proliferation of dispensaries in states that have legalized its use. Most patients using cannabis for medical purposes report getting advice from dispensaries, yet there has been little exploration of frontline dispensary staff practices. Objective: To describe the practices of frontline dispensary workers who interact with customers purchasing cannabis for medical purposes and assess whether dispensary practices are associated with medicalization of state cannabis laws (degree to which they resemble regulation of prescription or over-the-counter drugs) and statewide adult use. Design, Setting, and Participants: This nationwide cross-sectional survey study was conducted from February 13, 2020, to October 2, 2020, using an online survey tool. Potential respondents were eligible if they reported working in a dispensary that sells tetrahydrocannabinol-containing products and interacting with customers about cannabis purchases. Main Outcomes and Measures: Participant responses to questions about formulating customer recommendations and talking to customers about risks. Results: The 434 survey responses from 351 unique dispensaries were most often completed by individuals who identified as budtenders (40%), managers (32%), and pharmacists (13%). Most respondents reported basing customer recommendations on the customer's medical condition (74%), the experiences of other customers (70%), the customer's prior experience with cannabis (67%), and the respondent's personal experience (63%); fewer respondents relied on clinician input (40%), cost (45%), or inventory (12%). Most respondents routinely advised customers about safe storage and common adverse effects, but few counseled customers about cannabis use disorder, withdrawal, motor vehicle collision risk, or psychotic reactions. A higher state medicalization score was significantly associated with using employer training (odds ratio, 1.41; 95% CI, 1.18-1.67) and physician or clinician input (odds ratio, 1.23; 95% CI, 1.05-1.43) as a basis for recommendation. Medicalization score was not associated with counseling about cannabis risks. Conclusions and Relevance: This survey study provides insight into how frontline dispensary staff base cannabis recommendations and counsel about risks. The findings may have utility for clinicians to counsel patients who purchase cannabis, customers who want to be prepared for a dispensary visit, and policy makers whose decisions affect cannabis laws.

The influence of POLST on treatment intensity at the end of life: A systematic review.

BACKGROUND: Despite its widespread implementation, it is unclear whether Physician Orders for Life-Sustaining Treatment (POLST) are safe and improve the delivery of care that patients desire. We sought to systematically review the influence of POLST on treatment intensity among patients with serious illness and/or frailty. METHODS: We performed a systematic review of POLST and similar programs using MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, Cochrane Database for Systematic Reviews, and PsycINFO, from inception through February 28, 2020. We included adults with serious illness and/or frailty with life expectancy <1 year. Primary outcomes included place of death and receipt of high-intensity treatment (i.e., hospitalization in the last 30- and 90-days of life, ICU admission in the last 30-days of life, and number of care setting transitions in last week of life). RESULTS: Among 104,554 patients across 20 observational studies, 27,090 had POLST. No randomized controlled trials were identified. The mean age of POLST users was 78.7 years, 55.3% were female, and 93.0% were white. The majority of POLST users (55.3%) had orders for comfort measures only. Most studies showed that, compared to full treatment orders on POLST, treatment limitations were associated with decreased in-hospital death and receipt of high-intensity treatment, particularly in pre-hospital settings. However, in the acute care setting, a sizable number of patients likely received POLST-discordant care. The overall strength of evidence was moderate based on eight retrospective cohort studies of good quality that showed a consistent, similar direction of outcomes with moderate-to-large effect sizes. CONCLUSION: We found moderate strength of evidence that treatment limitations on POLST may reduce treatment intensity among patients with serious illness. However, the evidence base is limited and demonstrates potential unintended consequences of POLST. We identify several important knowledge gaps that should be addressed to help maximize benefits and minimize risks of POLST.
