Abstract
Abstract
Objective: Telehealth is an essential tool to provide access to care while reducing infection exposure for high-risk populations during the COVID-19 pandemic. Our study aims to examine factors associated with telehealth availability and usage among Medicare and dual-eligible recipients 1 year after implementation of the Medicare’s temporary telehealth waiver. Design, Setting, and Participant: A cross-sectional, phone survey with a national representative sample of Medicare recipients. We obtained a final study sample from the Winter 2021 COVID-19 Supplement of Medicare Current Beneficiary Survey dataset (N = 10 586). We examined associations for being offered and having had telehealth visits or any video telehealth visits during the pandemic since November 1, 2020. Main Outcome Measures: Our primary outcomes were being offered any telehealth, being offered any video telehealth, having had any telehealth visit, and having had any video telehealth. Results: Although dual eligibility was not significantly associated with being offered or having had any telehealth services during the pandemic, those who were dual eligible were more likely to have had video telehealth visits (adjusted odds ratio = 1.39, 95% confidence interval 1.04-1.86, P = .03) compared with those with non-dual eligibility. Recipients with disability eligibility, technology access, and severe chronic conditions were more likely to have been offered or have had telehealth. At the same time, those who lived in the nonmetropolitan area were less likely to have been offered or have had telehealth, including video telehealth. Conclusions: Our findings suggest that the federal waivers to expand telehealth services were successful in continuing care for vulnerable Medicare recipients. The providers’ specific outreach and intervention efforts to offer telehealth visits are crucial for dual-eligible recipients. To increase video telehealth uptake, technology access and services to rural areas should be prioritized.

Abstract
Background: Socioeconomic status has long been associated with population health and health outcomes. While ameliorating social determinants of health may improve health, identifying and targeting areas where feasible interventions are most needed would help improve health equity. We sought to identify inequities in health and social determinants of health (SDOH) associated with local economic distress at the county-level. Methods: For 3,131 counties in the 50 US states and Washington, DC (wherein approximately 325,711,203 people lived in 2019), we conducted a retrospective analysis of county-level data collected from County Health Rankings in two periods (centering around 2015 and 2019). We used ANOVA to compare thirty-three measures across five health and SDOH domains (Health Outcomes, Clinical Care, Health Behaviors, Physical Environment, and Social and Economic Factors) that were available in both periods, changes in measures between periods, and ratios of measures for the least to most prosperous counties across county-level prosperity quintiles, based on the Economic Innovation Group’s 2015–2019 Distressed Community Index Scores. Results: With seven exceptions, in both periods, we found a worsening of values with each progression from more to less prosperous counties, with least prosperous counties having the worst values (ANOVA p < 0.001 for all measures). Between 2015 and 2019, all except six measures progressively worsened when comparing higher to lower prosperity quintiles, and gaps between the least and most prosperous counties generally widened. Conclusions: In the late 2010s, the least prosperous US counties overwhelmingly had worse values in measures of Health Outcomes, Clinical Care, Health Behaviors, the Physical Environment, and Social and Economic Factors than more prosperous counties. Between 2015 and 2019, for most measures, inequities between the least and most prosperous counties widened. Our findings suggest that local economic prosperity may serve as a proxy for health and SDOH status of the community. Policymakers and leaders in public and private sectors might use long-term, targeted economic stimuli in low prosperity counties to generate local, community health benefits for vulnerable populations. Doing so could sustainably improve health; not doing so will continue to generate poor health outcomes and ever-widening economic disparities.

Abstract
Introduction/Objective: Previous studies have evaluated the implementation of standardized social determinants of health (SDOH) screening within healthcare settings, however, less is known about where screening gaps may exist following initial implementation based on facility characteristics. The objective of this study is to assess differences in screening rates for SDOH at a large, urban healthcare system. Methods: We used electronic health record data obtained from NYC Health + Hospitals primary care sites from 2019 to 2022. We calculated the mean number of visits that were SDOH screened by visit type, facility size, and the percentages of community characteristics. We conducted 4 logistic regression models predicting the odds of screening for any SDOH and for specific SDOH needs (housing, food, and medical cost assistance) based on facility type, facility size, and the socioeconomic characteristics of the surrounding community. Results: Among the 3 212 650 visits included, 16.90% were SDOH screened. Across all 4 multivariate logistic regression models predicting SDOH screening, a visit had significantly lower odds of being screened if based at a midsize or small facility, if it was a telemedicine visit, or based at a facility located in a zip-code with a higher percentage of SDOH needs. Conclusions: Our study found important differences in SDOH screening rates at a large, NYC-based health system based on size, visit type, and community level characteristics. In particular, our findings point to barriers related to facility size and telemedicine workflow that should be addressed to increase uptake of SDOH screening within different visits and facility types.

Abstract
Introduction: Opioid-related hospitalizations have risen dramatically, placing hospitals at the frontlines of the opioid epidemic. Medicaid expansion and 1115 waivers for substance use disorders (SUDs) are two key policies aimed at expanding access to care, including opioid use disorder (OUD) services. Yet, little is known about the relationship between these policies and the availability of hospital based OUD programs. The aim of this study is to determine whether state Medicaid expansion and adoption of 1115 waivers for SUDs are associated with hospital provision of OUD programs. Methods: We conducted a cross-sectional study of a random sample of hospitals (n = 457) from the American Hospital Association’s 2015 American Hospital Directory, compiled with the most recent publicly available community health needs assessment (2015–2018). Results: Controlling for hospital characteristics, overdose burden, and socio-demographic characteristics, both Medicaid policies were associated with hospital adoption of several OUD programs. Hospitals in Medicaid expansion states had significantly higher odds of implementing any program related to SUDs (OR: 1.740; 95% CI: 1.032–2.934) as well as some specific activities such as programs for OUD treatment (OR: 1.955; 95% CI: 1.245–3.070) and efforts to address social determinants of health (OR: 6.787; 95% CI: 1.308–35.20). State 1115 waivers for SUDs were not significantly associated with any hospital-based SUD activities. Conclusions: Medicaid expansion was associated with several hospital programs for addressing OUD. The differential availability of hospital-based OUD programs may indicate an added layer of disadvantage for low-income patients with SUD living in non-expansion states.

Abstract
Abstract
Background: Evidence suggests that harm reduction, a public health strategy aimed at reducing the negative consequences of a risky health behavior without requiring elimination of the behavior itself, may be a promising approach for minimizing drug-related harms while engaging individuals with substance use disorders (SUDs) in care. However, philosophical clashes between the medical and harm reduction models may pose barriers to adopting harm reduction approaches within medical settings. Objective: To identify barriers and facilitators to implementing a harm reduction approach toward care within healthcare settings. We conducted semi-structured interviews with providers and staff at three integrated harm reduction and medical care sites in New York. Design: Qualitative study using in-depth and semi-structured interviews. Participants: Twenty staff and providers across three integrated harm reduction and medical care sites across New York state. Approach: Interview questions focused on how harm reduction approaches were implemented and demonstrated in practice and barriers and facilitators to implementation, as well as questions based on the five domains of the Consolidated Framework for Implementation Research (CFIR). Key Results: We identified three key barriers to the adoption of the harm reduction approach that surrounded resource constraints, provider burnout, and interacting with external providers that do not have a harm reduction orientation. We also identified three facilitators to implementation, which included ongoing training both within and external to the clinic, team-based and interdisciplinary care, and affiliations with a larger healthcare system. Conclusions: This study demonstrated that while multiple barriers to implementing harm reduction informed medical care existed, health system leaders can adopt practices to mitigate barriers to adoption, such as value-based reimbursement models and holistic models of care that address the full spectrum of patient needs.

Abstract
Background: There are well-established guidelines for treating hypertension (HTN), yet only half of patients with HTN meet the defined target of < 140/90. Team-based care (TBC) is an evidence-based strategy for improving blood pressure (BP) management and control. TBC is defined as the provision of health services by at least two health professionals “who work collaboratively with patients and their caregivers to accomplish shared goals to achieve coordinated, high-quality care”. However, primary care practices experience challenges to implementing TBC principles and care processes; these are more pronounced in small independent practice settings (SIPs). Practice facilitation (PF) is an implementation strategy that may overcome barriers to adopting evidence-based TBC to improve HTN management in SIPs. Methods: Using a stepped wedge randomized controlled trial design, we will test the effect of PF on the adoption of TBC to improve HTN management in small practices (< 5 FTE clinicians) in New York City, and the impact on BP control compared with usual care. We will enroll 90 SIPs and randomize them into one of three 12-month intervention waves. Practice facilitators will support SIPs to adopt TBC principles to improve implementation of five HTN management strategies (i.e., panel management, population health, measuring BP, supporting medication adherence, self-management). The primary outcome is the adoption of TBC for HTN management measured at baseline and 12 months. Secondary outcomes include the rate of BP control and sustainability of TBC and BP outcomes at 18 months. Aggregated data on BP measures are collected every 6 months in all clusters so that each cluster provides data points in both the control and intervention conditions. Using a mixed methods approach, we will also explore factors that influence the effectiveness of PF at the organization and team level. Discussion: This study will provide much-needed guidance on how to optimize adoption and sustainability of TBC in independent primary care settings to reduce the burden of disease related to suboptimal BP control and advance understanding of how facilitation works to improve implementation of evidence-based interventions.

Abstract
Abstract
Introduction: Though prior research shows that a range of important regulatory, market, community, and organizational factors influence the adoption of evidence-based practices (EBPs) among health care organizations, we have little understanding of how these factors relate to each other. To address this gap, we test a conceptual model that emphasizes indirect, mediated effects among key factors related to HIV testing in substance use disorder treatment organizations (SUTs), a critical EBP during the US opioid epidemic. Methods: We draw on nationally representative data from the 2014 (n = 697) and 2017 (n = 657) National Drug Abuse Treatment System Survey (NDATSS) to measure the adoption of HIV testing among the nation's SUTs and their key organizational characteristics; we also draw on data from the US Census Bureau; Centers for Disease Control; and legislative sources to measure regulatory and community environments. We estimate cross-sectional and longitudinal structural equation models (SEM) to test the proposed model. Results: Our longitudinal model of the adoption of HIV testing by SUTs in the United States identifies a pathway by which community and market characteristics (rurality and the number of other SUTs in the area) are related to key sociotechnical characteristics of these organizations (alignment of clients, staff, and harm-reduction culture) that, in turn, are related to the adoption of this EBP. Conclusions: Results also show the importance of developing conceptual models that include indirect effects to account for organizational adoption of EBPs.

Abstract
Background: Hospitals are well-positioned to integrate harm reduction into their workflow. However, the extent to which hospitals across the United States are adopting these strategies remains unknown. Objectives: To assess what factors are associated with hospital adoption of harm reduction/risk education strategies, and trends of adoption across time. Methods: We constructed a dataset marking implementation of harm reduction/risk education strategies for a 20% random sample of nonprofit hospitals in the U.S (n = 489) using 2019–2021 community health needs assessments (CHNAs) and implementation strategies obtained from hospital websites. We used two-level mixed effects logistic regression to test the association between adoption of these activities and organizational and community-level variables. We also compared the proportion of hospitals that adopted these strategies in the 2019–2021 CHNAs to an earlier cohort (2015–2018.) Results: In the 2019–2021 CHNAs, 44.7% (n = 219) of hospitals implemented harm reduction/risk education programs, compared with 34.1% (n = 156) in the 2015–2018 cycle. In our multivariate model, hospitals that implemented harm reduction/risk education programs had higher odds of having adopted three or more additional substance use disorder (SUD) programs (OR: 10.5: 95% CI: 5.35–20.62), writing the CHNA with a community organization (OR: 2.14; 95% CI: 1.15–3.97), and prioritizing SUD as a top three need in the CHNA (OR: 2.63; 95% CI: 1.54–4.47.) Conclusions: Our results suggest that hospitals with an existing SUD infrastructure and with connections to community are more likely to implement harm reduction/risk education programs. Policymakers should consider these findings when developing strategies to encourage hospital implementation of harm reduction activities.

Abstract
Background: Substance use disorders (SUDs) are at a national high, with significant morbidity and mortality. Harm reduction, a public-health strategy aimed at reducing the negative consequences of a risky behavior without necessarily eliminating the behavior, represents a useful approach to engage patients with SUDs in care. The objective of this article is to describe how 3 medical practices operationalized harm reduction as a framework toward patient care and identify the common practices undertaken across these settings to integrate harm reduction and medical care. Methods: We conducted a qualitative study using in-depth, semistructured interviews with 20 staff and providers at 3 integrated harm reduction and medical care sites across New York State from March to June 2021. Interview questions focused on how harm reduction approaches were implemented, how harm reduction philosophies were demonstrated in practice, and barriers to adoption. Results: The interviews resulted in 8 main themes of integrated harm reduction medical care: 1) role of provider as both learner and informer; 2) pragmatic measures of success; 3) collaborative and interdisciplinary care teams; 4) developing a stigma-free culture; 5) creating a comfortable and welcoming physical space; 6) low-threshold care with flexible scheduling; and; 7) reaching beyond the clinic to disseminate harm reduction orientation; and 8) creating robust referral networks to enhance transitions of care. These themes existed at the patient-provider level (#1 to 3), the organizational level (#4 to 6), and the level extending beyond the clinic (#7 to 8). Conclusions: All 3 sites followed 8 common themes in delivering harm reduction–informed care, most of which are consistent with the broader movement toward patient-centered care. These practices demonstrate how medical providers may overcome some of the barriers imposed by the medical model and successfully integrate harm reduction as an orienting framework toward care delivery.

Abstract
Abstract
Introduction: There is growing recognition of the importance of addressing the social determinants of health in efforts to improve health equity. In dense urban environments such as New York City, disparities in chronic health conditions (e.g., cardiovascular disease) closely mimic inequities in social factors such as income, education, and housing. Although there is a wealth of data on these social factors in New York City, little is known about how to rapidly use available data sources to address health disparities. Methods: Semistructured interviews were conducted with key stakeholders (N=11) from across the public health landscape in New York City (health departments, healthcare delivery systems, and community-based organizations) to assess perspectives on how social determinants of health data can be used to address cardiovascular disease and health equity, what data-driven tools would be useful, and challenges to using these data sources and developing tools. A matrix analysis approach was used to analyze the interview data. Results: Stakeholders were optimistic about using social determinants of health data to address health equity by delivering holistic care, connecting people with additional resources, and increasing investments in under-resourced communities. However, interviewees noted challenges related to the quality and timeliness of social determinants of health data, interoperability between data systems, and lack of consistent metrics related to cardiovascular disease and health equity. Conclusions: Future research on this topic should focus on mitigating the barriers to using social determinants of health data, which includes incorporating social determinants of health data from other sectors. There is also a need to assess how data-driven solutions can be implemented within and across communities and organizations.

Abstract
Abstract
Background: Acute-care interventions that identify patients with substance use disorders (SUDs), initiate treatment, and link patients to community-based services, have proliferated in recent years. Yet, much is unknown about the specific strategies being used to support continuity of care from emergency department (ED) or inpatient hospital settings to community-based SUD treatment. In this scoping review, we synthesize the existing literature on patient transition interventions, and form an initial typology of reported strategies. Methods: We searched Pubmed, Embase, CINAHL and PsychINFO for peer-reviewed articles published between 2000 and 2021 that studied interventions linking patients with SUD from ED or inpatient hospital settings to community-based SUD services. Eligible articles measured at least one post-discharge treatment outcome and included a description of the strategy used to promote linkage to community care. Detailed information was extracted on the components of the transition strategies and a thematic coding process was used to categorize strategies into a typology based on shared characteristics. Facilitators and barriers to transitions of care were synthesized using the Consolidated Framework for Implementation Research. Results: Forty-five articles met inclusion criteria. 62% included ED interventions and 44% inpatient interventions. The majority focused on patients with opioid (71%) or alcohol (31%) use disorder. The transition strategies reported across studies were heterogeneous and often not well described. An initial typology of ten transition strategies, including five pre- and five post-discharge transition strategies is proposed. The most common strategy was scheduling an appointment with a community-based treatment provider prior to discharge. A range of facilitators and barriers were described, which can inform efforts to improve hospital-to-community transitions of care. Conclusions: Strategies to support transitions from acute-care to community-based SUD services, although critical for ensuring continuity of care, vary greatly across interventions and are inconsistently measured and described. More research is needed to classify SUD care transition strategies, understand their components, and explore which lead to the best patient outcomes.

Abstract
Importance: Safety-net hospitals (SNHs) are ideal sites to deliver addiction treatment to patients with substance use disorders (SUDs), but the availability of these services within SNHs nationwide remains unknown. Objective: To examine differences in the delivery of different SUD programs in SNHs vs non-SNHs across the US and to determine whether these differences are increased in certain types of SNHs depending on ownership. Design, Setting, and Participants: This cross-sectional analysis used data from the 2021 American Hospital Association Annual Survey of Hospitals to examine the associations of safety-net status and ownership with the availability of SUD services at acute care hospitals in the US. Data analysis was performed from January to March 2022. Main Outcomes and Measures: This study used 2 survey questions from the American Hospital Association survey to determine the delivery of 5 hospital-based SUD services: screening, consultation, inpatient treatment services, outpatient treatment services, and medications for opioid use disorder (MOUD). Results: A total of 2846 hospitals were included: 409 were SNHs and 2437 were non-SNHs. The lowest proportion of hospitals reported offering inpatient treatment services (791 hospitals [27%]), followed by MOUD (1055 hospitals [37%]), and outpatient treatment services (1087 hospitals [38%]). The majority of hospitals reported offering consultation (1704 hospitals [60%]) and screening (2240 hospitals [79%]). In multivariable models, SNHs were significantly less likely to offer SUD services across all 5 categories of services (screening odds ratio [OR], 0.62 [95% CI, 0.48-0.76]; consultation OR, 0.62 [95% CI, 0.47-0.83]; inpatient services OR, 0.73 [95% CI, 0.55-0.97]; outpatient services OR, 0.76 [95% CI, 0.59-0.99]; MOUD OR, 0.6 [95% CI, 0.46-0.78]). With the exception of MOUD, public or for-profit SNHs did not differ significantly from their non-SNH counterparts. However, nonprofit SNHs were significantly less likely to offer all 5 SUD services compared with their non-SNH counterparts (screening OR, 0.52 [95% CI, 0.41-0.66]; consultation OR, 0.56 [95% CI, 0.44-0.73]; inpatient services OR, 0.45 [95% CI, 0.33-0.61]; outpatient services OR, 0.58 [95% CI, 0.44-0.76]; MOUD OR, 0.61 [95% CI, 0.46-0.79]). Conclusions and Relevance: In this cross-sectional study of SNHs and non-SNHs, SNHs had significantly lower odds of offering the full range of SUD services. These findings add to a growing body of research suggesting that SNHs may face additional barriers to offering SUD programs. Further research is needed to understand these barriers and to identify strategies that support the adoption of evidence-based SUD programs in SNH settings.

Abstract
Synchronous home-based telemedicine for primary care experienced growth during the coronavirus disease 2019 pandemic. A review was conducted on the evidence reporting on the feasibility of synchronous telemedicine implementation within primary care, barriers and facilitators to implementation and use, patient characteristics associated with use or nonuse, and quality and cost/revenue-related outcomes. Initial database searches yielded 1,527 articles, of which 22 studies fulfilled the inclusion criteria. Synchronous telemedicine was considered appropriate for visits not requiring a physical examination. Benefits included decreased travel and wait times, and improved access to care. For certain services, visit quality was comparable to in-person care, and patient and provider satisfaction was high. Facilitators included proper technology, training, and reimbursement policies that created payment parity between telemedicine and in-person care. Barriers included technological issues, such as low technical literacy and poor internet connectivity among certain patient populations, and communication barriers for patients requiring translators or additional resources to communicate.

Abstract
Objectives Hospitalizations are an important opportunity to address substance use through inpatient services, outpatient care, and community partnerships, yet the extent to which nonprofit hospitals prioritize such services across time remains unknown. The objective of this study is to examine trends in nonprofit hospitals' prioritization and implementation of substance use disorder (SUD) programs. Methods We assessed trends in hospital prioritization of substance use as a top five community need and hospital implementation of SUD programing at nonprofit hospitals between 2015 and 2021 using two waves (wave 1: 2015-2018; wave 2: 2019-2021) by examining hospital community benefit reports. We utilized t or χ2 tests to understand whether there were significant differences in the prioritization and implementation of SUD programs across waves. We used multilevel logistic regression to evaluate the relation between prioritization and implementation of SUD programs, hospital and community characteristics, and wave. Results Hospitals were less likely to have prioritized SUD but more likely to have implemented SUD programs in the most recent 3 years compared, even after adjusting for the local overdose rate and hospital-and community-level variables. Although most hospitals consistently prioritized and implemented SUD programs during the 2015-2021 period, a 11% removed and 15% never adopted SUD programs at all, despite an overall increase in overdose rates. Conclusions Our study identified gaps in hospital SUD infrastructure during a time of elevated need. Failing to address this gap reflects missed opportunities to engage vulnerable populations, provide linkages to treatment, and prevent complications of substance use.

Abstract
BACKGROUND: Cardiovascular disease is the leading cause of morbidity and mortality worldwide. Prior research suggests that social determinants of health have a compounding effect on health and are associated with cardiovascular disease. This scoping review explores what and how social determinants of health data are being used to address cardiovascular disease and improve health equity. METHODS AND RESULTS: After removing duplicate citations, the initial search yielded 4110 articles for screening, and 50 studies were identified for data extraction. Most studies relied on similar data sources for social determinants of health, including geo-coded electronic health record data, national survey responses, and census data, and largely focused on health care access and quality, and the neighborhood and built environment. Most focused on developing interventions to improve health care access and quality or characterizing neighborhood risk and individual risk. CONCLUSIONS: Given that few interventions addressed economic stability, education access and quality, or community context and social risk, the potential for harnessing social determinants of health data to reduce the burden of cardiovascular disease remains unrealized.

We conducted a PubMed search of the peer-reviewed and gray literature using the terms “social determinants of health” and “New York City,” with the Boolean operator “AND.” We then conducted a search of the “gray literature,” defined as sources outside of standard bibliographic databases, using similar terms. We extracted publicly available data sources containing NYC-based data. In defining SDOH, we used the framework outlined by the CDC’s Healthy People 2030, which uses a place-based framework to categorize 5 domains of SDOH: (1) healthcare access and quality; (2) education access and quality; (3) social and community context; (4) economic stability; and (5) neighborhood and built environment. We identified 29 datasets from the PubMed search, and 34 datasets from the gray literature, resulting in 63 datasets related to SDOH in NYC. Of these, 20 were available at the zip code level, 18 at the census tract-level, 12 at the community-district level, and 13 at the census block or specific address level. Community-level SDOH data are readily attainable from many public sources and can be linked with health data on local geographic-levels to assess the effect of social and community factors on individual health outcomes.

Abstract
Introduction/Objectives: Patient activation describes the knowledge, skills, and confidence that allow patients to actively engage in managing their health. Prior studies have found a strong relationship between patient activation and clinical outcomes, costs of care, and patient experience. Patients who are obese or overweight may be less engaged than normal weight patients due to lower confidence or stigma associated with their weight. The objective of this study is to examine whether weight status is associated with patient activation and its sub-domains (confidence, communication, information-seeking behavior). Methods: This repeated cross-sectional study of the 2011 to 2013 Medicare Current Beneficiary Survey (MCBS) included a nationally representative sample of 13,721 Medicare beneficiaries. Weight categories (normal, overweight, obese) were based on body mass index. Patient activation (high, medium, low) was based on responses to the MCBS Patient Activation Supplement. Results: We found no differences in overall patient activation by weight categories. However, compared to those with normal weight, people with obesity had a higher relative risk (RRR 1.24; CI 1.09-1.42) of “low” rather than “high” confidence. Respondents with obesity had a lower relative risk (RRR 0.82; CI 0.73-0.92) of “low” rather than “high” ratings of communication with their doctor. Discussion and Conclusions: Though patients with obesity may be less confident in their ability to manage their health, they are more likely to view their communication with physicians as conducive to self-care management. Given the high receptivity among patients with obesity toward physician communication, physicians may be uniquely situated to guide and support patients in gaining the confidence they need to reach weight loss goals.

Abstract
Objectives Although video visits may offer some benefits over the telephone, not all patients may be equipped to access video telemedicine, raising questions surrounding access disparities. The aim of this study is to examine patient characteristics associated with the use of phone versus video-enabled tele-medication for opioid use disorders (MOUD) during COVID-19. Methods This study uses data from a nonurban integrated substance use disorder treatment site in New York to examine patient characteristics associated with the modality of tele-MOUD care. The provider did not offer in-person care. Multivariable regression models were used to assess the association between patient's primary mode of tele-MOUD and patient demographic characteristics. Additional analysis of new patient inductions examined associations between mode of tele-MOUD induction and 30-day follow-up receipt. Results Of the 4557 tele-MOUD encounters, 76.92% were video and 23.08% were telephone visits. Older patients had significantly higher odds of primarily using telephone (odds ratio [OR]: 0.580; 95% confidence interval [CI]: 0.045, 1.115). Patients with higher education (OR: -0.791; 95% CI: -1.418, -0.168), recent overdose (OR: -0.40; 95% CI: -0.793, -0.010), and new patients (OR: 0.484; 95% CI: -0.945, 0.023) were significantly less likely to rely on telephone. Of 336 new patient initiations, 31 were conducted by telephone while 305 were conducted through video. The mode of new patient initiation was not associated with a follow-up visit within 30 days of initiation. Conclusions Telemedicine may increase access to MOUD, though certain patients may rely on different forms of telemedicine. Attention must be paid to policies that promote equitable access to both video and telephone tele-MOUD visits.

Abstract
Background: Studies specifically focused on patients’ perspectives on telemedicine visits in primary and behavioral health care are fairly limited and have often focused on highly selected populations or used overall satisfaction surveys. Objective: To examine patient perspectives on the shift to telemedicine, the remote delivery of health care via the use of electronic information and communications technology, in primary and behavioral health care in Federally Qualified Health Centers (FQHCs) during COVID-19. Design: Semi-structured interviews were conducted using video conference with patients and caregivers between October and December 2020. Participants: Providers from 6 FQHCs nominated participants. Eighteen patients and caregivers were interviewed: 6 patients with only primary care visits; 5 with only behavioral health visits; 3 with both primary care and behavioral health visits; and 4 caregivers of children with pediatric visits. Approach: Using a protocol-driven, rapid qualitative methodology, we analyzed the interview data and assessed the quality of care, benefits and challenges of telemedicine, and use of telemedicine post-pandemic. Key Results: Respondents broadly supported the option of home-based synchronous telemedicine visits in primary and behavioral health care. Nearly all respondents appreciated remote visits, largely because such visits provided a safe option during the pandemic. Patients were generally satisfied with telemedicine and believed the quality of visits to be similar to in-person visits, especially when delivered by a provider with whom they had established rapport. Although most respondents planned to return to mostly in-person visits when considered safe to do so, they remained supportive of the continued option for remote visits as remote care addresses some of the typical barriers faced by low-income patients. Conclusions: Addressing digital literacy challenges, enhancing remote visit privacy, and improving practice workflows will help ensure equitable access to all patients as we move to a new post-COVID-19 “normal” marked by increased reliance on telemedicine and technology.

Abstract
Introduction: While racial/ethnic disparities in the use of opioid use disorder (OUD) treatment in outpatient settings are well documented in the literature, little is known about racial/ethnic disparities in access to hospital-based OUD services. This study examines the relationship between hospital-based or initiated OUD services and the racial/ethnic composition of the surrounding community. Methods: We constructed a dataset marking the implementation of eight OUD strategies for a 20% random sample of nonprofit hospitals in the United States based on 2015–2018 community health needs assessments. We tested the significance of the relationship between each OUD strategy and the racial/ethnic composition of the surrounding county using two-level mixed effects logistic regression models that considered the hierarchical structure of the data of hospitals within states while controlling for hospital-level county-level, and state-level covariates. Results: In both unadjusted and adjusted models, we found that hospital adoption of several OUD services significantly varied based on the percentage of Black or Hispanic residents in their communities. Even after controlling for hospital size, the overdose burden in the community, community socioeconomic characteristics, and state funding, hospitals in communities with high percentage of Black or Hispanic residents had significantly lower odds of offering the most common hospital-based programs to address OUD – including programs that increase access to formal treatment services, prescriber guidelines, targeted risk education and harm reduction, and community coalitions to address opioid use. Conclusions: Hospital adoption of many OUD services varies based on the percentage of Black or Hispanic residents in their communities. More attention should be paid to the role, ability, and strategies that hospitals can assume to address disparities among OUD treatment and access needs, especially those that serve communities with a high concentration of Black and Hispanic residents.

Abstract
Policy Points Telehealth has many potential advantages during an infectious disease outbreak such as the COVID-19 pandemic, and the COVID-19 pandemic has accelerated the shift to telehealth as a prominent care delivery mode. Not all health care providers and patients are equally ready to take part in the telehealth revolution, which raises concerns for health equity during and after the COVID-19 pandemic. Without proactive efforts to address both patient- and provider-related digital barriers associated with socioeconomic status, the wide-scale implementation of telehealth amid COVID-19 may reinforce disparities in health access in already marginalized and underserved communities. To ensure greater telehealth equity, policy changes should address barriers faced overwhelmingly by marginalized patient populations and those who serve them. Context: The COVID-19 pandemic has catalyzed fundamental shifts across the US health care delivery system, including a rapid transition to telehealth. Telehealth has many potential advantages, including maintaining critical access to care while keeping both patients and providers safe from unnecessary exposure to the coronavirus. However, not all health care providers and patients are equally ready to take part in this digital revolution, which raises concerns for health equity during and after the COVID-19 pandemic. Methods: The study analyzed data about small primary care practices’ telehealth use and barriers to telehealth use collected from rapid-response surveys administered by the New York City Department of Health and Mental Hygiene's Bureau of Equitable Health Systems and New York University from mid-April through mid-June 2020 as part of the city's efforts to understand how primary care practices were responding to the COVID-19 pandemic following New York State's stay-at-home order on March 22. We focused on small primary care practices because they represent 40% of primary care providers and are disproportionately located in low-income, minority or immigrant areas that were more severely impacted by COVID-19. To examine whether telehealth use and barriers differed based on the socioeconomic characteristics of the communities served by these practices, we used the Centers for Disease Control and Prevention Social Vulnerability Index (SVI) to stratify respondents as being in high-SVI or low-SVI areas. We then characterized respondents’ telehealth use and barriers to adoption by using means and proportions with 95% confidence intervals. In addition to a primary analysis using pooled data across the five waves of the survey, we performed sensitivity analyses using data from respondents who only took one survey, first wave only, and the last two waves only. Findings: While all providers rapidly shifted to telehealth, there were differences based on community characteristics in both the primary mode of telehealth used and the types of barriers experienced by providers. Providers in high-SVI areas were almost twice as likely as providers in low-SVI areas to use telephones as their primary telehealth modality (41.7% vs 23.8%; P <.001). The opposite was true for video, which was used as the primary telehealth modality by 18.7% of providers in high-SVI areas and 33.7% of providers in low-SVI areas (P <0.001). Providers in high-SVI areas also faced more patient-related barriers and fewer provider-related barriers than those in low-SVI areas. Conclusions: Between April and June 2020, telehealth became a prominent mode of primary care delivery in New York City. However, the transition to telehealth did not unfold in the same manner across communities. To ensure greater telehealth equity, policy changes should address barriers faced overwhelmingly by marginalized patient populations and those who serve them.

Abstract
Abstract
Objective: To review the frequency as well as the pros and cons of telephone and video-enabled telemedicine during the first 9 months of the Coronavirus disease 2019 (COVID-19) pandemic as experienced by safety net providers across New York State (NYS). Methods: Analysis of visits to 36 community health centers (CHCs) in NYS by modality (telephone vs video) from February to November 2020. Semi-structured interviews with 25 primary care, behavioral health, and pediatric providers from 8 CHCs. Findings: In the week following the NYS stay-at-home order, video and telephone visits rose from 3.4 and 0% of total visits to 14.9 and 22.3%. At its peak, more than 60% of visits were conducted via telemedicine (April 2020) before tapering off to about 30% of visits (August 2020). Providers expressed a strong preference for video visits, particularly for situations when visual assessments were needed. Yet, more visits were conducted over telephone than video at all points throughout the pandemic. Video-specific advantages included enhanced ability to engage patients and use of visual cues to get a comprehensive look into the patient’s life, including social supports, hygiene, and medication adherence. Telephone presented unique benefits, including greater privacy, feasibility, and ease of use that make it critical to engage with key populations and as a backup for when video was not an option. Conclusions: Despite challenges, providers reported positive experiences delivering care remotely using both telephone and video during the COVID-19 pandemic and believe both modalities are critical for enabling access to care in the safety net.

Abstract
BACKGROUND/OBJECTIVES: Patient activation encompasses the knowledge, skills, and confidence that equip adults to participate actively in their healthcare. Patients with hearing loss may be less able to participate due to poor aural communication. We examined whether difficulty hearing is associated with lower patient activation. DESIGN: Cross-sectional study. SETTING/PARTICIPANTS: A nationally representative sample of Americans aged 65 years and older (n = 13 940) who participated in the Medicare Current Beneficiary Survey (MCBS) during the years 2011 to 2013. MEASUREMENT: Self-reported degree of difficulty hearing (“no trouble,” “a little trouble,” and “a lot of trouble”) and overall activation based on aggregated scored responses to 16 questions from the MCBS Patient Activation Supplement: low activation (below the mean minus 0.5 SDs), high activation (above the mean plus 0.5 SDs), and medium activation (the remainder). Sociodemographic and self-reported clinical measures were also included. RESULTS: “A little trouble” hearing was reported by 5655 (40.6%) of respondents, and “a lot of trouble” hearing was reported by 893 (6.4%) of respondents. Difficulty hearing was significantly associated with low patient activation: in analyses using multivariable multinomial logistic regression, respondents with “a little trouble” hearing had 1.42 times the risk of low vs high activation (95% confidence interval [CI] = 1.27-1.58), and those with “a lot of trouble” hearing had 1.70 times the risk of low vs high activation (95% CI = 1.29-2.11), compared with those with “no trouble” hearing. CONCLUSIONS: Nearly half of people aged 65 years and older reported difficulty hearing, and those reporting difficulty were at risk of low patient activation. That risk rose with increased difficulty hearing. Given the established link between activation and outcomes of care, and in view of the association between hearing loss and poor healthcare quality and outcomes, clinicians may be able to improve care for people with hearing loss by attending to aural communication barriers.
