Machine Learning to Identify Clusters in Family Medicine Diplomate Motivations and Their Relationship to Continuing Certification Exam Outcomes: Findings and Potential Future Implications.

BACKGROUND: The potential for machine learning (ML) to enhance the efficiency of medical specialty boards has not been explored. We applied unsupervised ML to identify archetypes among American Board of Family Medicine (ABFM) Diplomates regarding their practice characteristics and motivations for participating in continuing certification, then examined associations between motivation patterns and key recertification outcomes. METHODS: Diplomates responding to the 2017 to 2021 ABFM Family Medicine continuing certification examination surveys selected motivations for choosing to continue certification. We used Chi-squared tests to examine difference proportions of Diplomates failing their first recertification examination attempt who endorsed different motivations for maintaining certification. Unsupervised ML techniques were applied to generate clusters of physicians with similar practice characteristics and motivations for recertifying. Controlling for physician demographic variables, we used logistic regression to examine the effect of motivation clusters on recertification examination success and validated the ML clusters by comparison with a previously created classification schema developed by experts. RESULTS: ML clusters largely recapitulated the intrinsic/extrinsic framework devised by experts previously. However, the identified clusters achieved a more equal partitioning of Diplomates into homogenous groups. In both ML and human clusters, physicians with mainly extrinsic or mixed motivations had lower rates of examination failure than those who were intrinsically motivated. DISCUSSION: This study demonstrates the feasibility of using ML to supplement and enhance human interpretation of board certification data. We discuss implications of this demonstration study for the interaction between specialty boards and physician Diplomates.

What Complexity Science Predicts About the Potential of Artificial Intelligence/Machine Learning to Improve Primary Care.

Primary care physicians are likely both excited and apprehensive at the prospects for artificial intelligence (AI) and machine learning (ML). Complexity science may provide insight into which AI/ML applications will most likely affect primary care in the future. AI/ML has successfully diagnosed some diseases from digital images, helped with administrative tasks such as writing notes in the electronic record by converting voice to text, and organized information from multiple sources within a health care system. AI/ML has less successfully recommended treatments for patients with complicated single diseases such as cancer; or improved diagnosing, patient shared decision making, and treating patients with multiple comorbidities and social determinant challenges. AI/ML has magnified disparities in health equity, and almost nothing is known of the effect of AI/ML on primary care physician-patient relationships. An intervention in Victoria, Australia showed promise where an AI/ML tool was used only as an adjunct to complex medical decision making. Putting these findings in a complex adaptive system framework, AI/ML tools will likely work when its tasks are limited in scope, have clean data that are mostly linear and deterministic, and fit well into existing workflows. AI/ML has rarely improved comprehensive care, especially in primary care settings, where data have a significant number of errors and inconsistencies. Primary care should be intimately involved in AI/ML development, and its tools carefully tested before implementation; and unlike electronic health records, not just assumed that AI/ML tools will improve primary care work life, quality, safety, and person-centered clinical decision making.

Setting the Target: Comparing Family Medicine Among US Allopathic Target Schools.

BACKGROUND AND OBJECTIVES: Despite the persistent primary care physician shortage over 2 decades of allopathic medical school expansion, some medical schools are absent a department of family medicine; these schools are designated as "target" schools. These absences are important because evidence has demonstrated the association between structured exposure to family medicine during medical school and the proportion of students who ultimately select a career in family medicine. In this study, we aimed to address part of this gap by defining and characterizing the current landscape of US allopathic target schools. METHODS: We identified allopathic target schools by reviewing all Liaison Committee of Medical Education (LCME) accredited institutions for the presence of a family medicine department. To compare these schools in terms of family medicine representation and outcomes, we curated descriptive data from publicly available websites, previously published family medicine match results, and school rankings for primary care. RESULTS: We identified 12 target schools (8.7% of all US allopathic accredited medical schools) with considerable heterogeneity in opportunities for family medicine engagement, leadership, and training. Target schools with greater family medicine representation had increased outcomes for family medicine workforce and primary care opportunities. CONCLUSION: With growing primary care workforce gaps, target schools have a responsibility to enhance family medicine presence and representation at their institutions. We provide recommendations at the institutional, specialty, and national level to increase family medicine representation at target schools, with the goal that all schools eventually establish a department of family medicine.

Small Independent Primary Care Practices Serving Socially Vulnerable Urban Populations.

PURPOSE: This mixed methods study sought to describe the extent to which family physicians in urban communities serve socially vulnerable patients and to better understand their practices, their challenges, and the structural supports that could facilitate their patient care. METHODS: We conducted a quantitative analysis of questionnaire data from 100% of US physicians recertifying for family medicine from 2017 to 2020. We conducted qualitative analysis of in-depth interviews with 22 physician owners of urban, small, independent practices who reported that the majority of their patients were socially vulnerable. RESULTS: In 2020, in urban areas across the United States, 19.3% of family physicians served in independent practices with 1 to 5 clinicians, down from 22.6% in 2017. Nearly one-half of these physicians reported that >10% of their patients were socially vulnerable. Interviews with 22 physicians who reported that the majority of their patients were socially vulnerable revealed 5 themes: (1) substantial time spent addressing access issues and social determinants of health, (2) minimal support from health care entities, such as independent practice associations and health plans, and insufficient connection to community-based organizations, (3) myriad financial challenges, (4) serious concerns about the future, and (5) deep personal commitment to serving socially vulnerable patients in independent practice. CONCLUSIONS: Small independent practices serving vulnerable patients in urban communities are surviving because deeply committed physicians are making personal sacrifices. Health equity-focused policies could decrease the burden on these physicians and bolster independent practices so that socially vulnerable patients continue to have options when seeking primary care.

Primary Care Physicians' Satisfaction With Interoperable Health Information Technology.

Importance: Enabling widespread interoperability-the ability of health information technology systems to exchange information and to use that information without special effort-is a primary focus of public policy on health information technology. More information on clinicians' experience using that technology can serve as one measure of the impact of that policy. Objective: To assess primary care physician perspectives on the state of interoperability. Design, Setting, and Participants: A cross-sectional survey of family medicine physicians in the US was conducted from December 12, 2021, to October 12, 2022. A sample of family medicine physicians who completed the Continuous Certification Questionnaire (CCQ), a required part of the American Board of Family Medicine certification process, which has a 100% response rate, were invited to participate. Main Outcomes and Measures: Eighteen items on the CCQ assessed experience accessing and using various information from outside organizations, including medications, immunizations, and allergies. Results: A total of 2088 physicians (1053 women [50%]; age reported categorically as either ≥50 years or <50 years) completed the CCQ interoperability questions in 2022. Of these respondents, 35% practiced in hospital or health system-owned practices, while 27% practiced in independently owned practices. Eleven percent were very satisfied with their ability to electronically access all 10 types of information from outside organizations included on the questionnaire, and a mean of 70% were at least somewhat satisfied. A total of 23% of family medicine physicians reported information from outside organizations was very easy to use, and an additional 65% reported that information was somewhat easy to use. Only 8% reported that information from different electronic health record (EHR) developers' products was very easy to use compared with 38% who reported information from the same EHR developer's product was very easy to use. Conclusions and Relevance: This survey study of family medicine physicians found modest and uneven improvement in physicians' experience with interoperability. These findings suggest that substantial heterogeneity in satisfaction by information type, source of information, EHR, practice type, ownership, and patient population necessitates diverse policy and strategies to improve interoperability.

Physician-Level Continuity of Care and Patient Outcomes in All-Payer Claims Database.

INTRODUCTION: Being one of the few existing measures of primary care functions, physician-level continuity of care (Phy-CoC) is measured by the weighted average of patient continuity scores. Compared with the well-researched patient-level continuity, Phy-CoC is a new instrument with limited evidence from Medicare beneficiaries. This study aimed to expand the patient sample to include patients of all ages and all types of insurance and reassess the associations between full panel-based Phy-CoC scores and patient outcomes. METHODS: Cross-sectional analysis at patient-level using Virginia All-Payer Claims Database (VA-APCD). Phy-CoC scores were calculated by averaging patient's Bice-Boxerman Index scores and weighted by the total number of visits. Patient outcomes included total cost and preventable hospitalization. RESULTS: In a sample of 1.6 million Virginians, patients who lived in rural areas or had Medicare as primary insurance were more likely to be attributed to physicians with the highest Phy-CoC scores. Across all adult patient populations, we found that being attributed to physicians with higher Phy-CoC was associated with 7%-11.8% higher total costs, but was not associated with the odds of preventable hospitalization. Results from models with interactions revealed nuanced associations between Phy-CoC and total cost with patient's age and comorbidity, insurance payer, and the specialty of their physician. CONCLUSIONS: In this comprehensive examination of Phy-CoC using all populations from the VA-APCD, we found an overall positive association of higher full panel-based Phy-CoC with total cost, but a non-significant association with the risk of preventable hospitalization. Achieving higher full panel-based Phy-CoC may have unintended cost implications.

Prevalence and Predictors of Burnout Among Resident Family Physicians.

BACKGROUND AND OBJECTIVES: Resident burnout may affect career choices and empathy. We examined predictors of burnout among family medicine residents. METHODS: We used data from the 2019-2021 American Board of Family Medicine Initial Certification Questionnaire, which is required of graduating residents. Burnout was a binary variable defined as reporting callousness or emotional exhaustion once a week or more. We evaluated associations using bivariate and multilevel multivariable regression analyses. RESULTS: Among 11,570 residents, 36.4% (n=4,211) reported burnout. This prevalence did not significantly vary from 2019 to 2021 and was not significantly attributable to the residency program (ICC=0.07). Residents identifying as female reported higher rates of burnout (39.0% vs 33.4%, AOR=1.29 [95% CI 1.19-1.40]). Residents reporting Asian race (30.5%, AOR=0.78 [95% CI 0.70-0.86]) and Black race (32.3%, AOR=0.71 [95% CI 0.60-0.86]) reported lower odds of burnout than residents reporting White race (39.2%). We observed lower rates among international medical graduates (26.7% vs 40.3%, AOR=0.54 [95% CI 0.48-0.60]), those planning to provide outpatient continuity care (36.0% vs 38.7%, AOR=0.77 [95% CI 0.68-0.86]), and those at smaller programs (31.7% for <6 residents per class vs 36.3% for 6-10 per class vs 40.2% for >10 per class). Educational debt greater than $250,000 was associated with higher odds of burnout than no debt (AOR=1.29 [95% CI 1.15-1.45]). CONCLUSIONS: More than one-third of recent family medicine residents reported burnout. Odds of burnout varied significantly with resident and program characteristics.

Differences in Physician Performance and Self-rated Confidence on High- and Low-Stakes Knowledge Assessments in Board Certification.

INTRODUCTION: Evidence links assessment to optimal learning, affirming that physicians are more likely to study, learn, and practice skills when some form of consequence ("stakes") may result from an assessment. We lack evidence, however, on how physicians' confidence in their knowledge relates to performance on assessments, and whether this varies based on the stakes of the assessment. METHODS: Our retrospective repeated-measures design compared differences in patterns of physician answer accuracy and answer confidence among physicians participating in both a high-stakes and a low-stakes longitudinal assessment of the American Board of Family Medicine. RESULTS: After 1 and 2 years, participants were more often correct but less confident in their accuracy on a higher-stakes longitudinal knowledge assessment compared with a lower-stakes assessment. There were no differences in question difficulty between the two platforms. Variation existed between platforms in time spent answering questions, use of resources to answer questions, and perceived question relevance to practice. DISCUSSION: This novel study of physician certification suggests that the accuracy of physician performance increases with higher stakes, even as self-reported confidence in their knowledge declines. It suggests that physicians may be more engaged in higher-stakes compared with lower-stakes assessments. With medical knowledge growing exponentially, these analyses provide an example of the complementary roles of higher- and lower-stakes knowledge assessment in supporting physician learning during continuing specialty board certification.

Variation in Practice Patterns of Early- and Later-Career Family Physicians.

INTRODUCTION: Understanding how physicians' practice patterns change over a career is important for workforce and medical education planning. This study examined trends in self-reported practice activity among early- and later-career stage family physicians (FPs). METHODS: Data on early career FPs came from the American Board of Family Medicine's National Graduate Survey (NGS) and on later career FPs from its Continuous Certification Questionnaire (CCQ). Both cohorts could complete the Practice Demographic Survey (PDS) 3 years later. Longitudinal cohorts were from 2016 to 2019 and 2017 to 2020, respectively. All surveys included identical items on scope of practice, practice type, organization, and location. We characterized physicians as outpatient continuity only, outpatient and inpatient care (mixed practice), and no outpatient continuity (for example, hospitalist). We conducted repeated cross-sectional and longitudinal analysis of practice type. RESULTS: Our sample included 8,492 NGS and 30,491 CCQ FPs. In both groups, the vast majority provided outpatient continuity of care (77% to 81%). Approximately 25% of NGS had a mixed practice compared with approximately 16% of the CCQ group. The percent of FPs who had a mixed practice declined in both groups (34.21% to 27.10% and 23.88% to 19.33%). In both groups, physicians with higher odds of leaving mixed practice were in metropolitan counties or changed practice types. CONCLUSION: Although early-career FPs more frequently reported providing both inpatient and outpatient care and serving as hospitalists compared with later-career FPs, both groups had a decline in frequency of providing mixed practice. This change after only 3 years in practice has significant implications for patient care and medical education.

Defining comprehensiveness in primary care: a scoping review.

Introduction The term comprehensiveness was introduced into the literature as early as the 1960s and is regarded as a core attribute of primary care. Although comprehensive care is a primary care research priority encompassing patient and provider experience, cost, and health outcomes, there has been a lack of focus on consolidating existing definitions. Aim To unify definitions of comprehensiveness in primary care. Methods The PRISMA extension for scoping reviews was followed, hierarchically filtering 'comprehensiveness' MeSH terms and literature-defined affiliated terms. Snowballing methods were used to include additional literature from known experts. Articles were systematically reviewed with a three-clinician team. Results The initial search populated 679 607 articles, of which 25 were included. Identified key terms include: whole-person care (WPC), range of services, and referral to specialty care. WPC is the extent which primary care physicians (PCPs) consider the physical, emotional, and social aspects of a patient's health. It has been shown to positively impact clinical costs and outcomes, satisfaction, and trust. Range of services encompasses most health problems to reduce unnecessary spending on specialty care and promote continuity. Referral to specialty care is utilized when PCPs cannot provide the necessary services - balancing depth and breadth of care with the limitations of primary care scope. Discussion This scoping review unified the interrelatedness of comprehensiveness's main aspects - whole-person care, range of services, and referral to specialty care - framing a working, evidence-based definition: managing most medical care needs and temporarily complementing care with special integrated services in the context of patient's values, preferences, and beliefs.

COVID-19 Vaccine Strategy Left Small Primary Care Practices On The Sidelines.

We report on the experience of small primary care practices participating in a national clinical registry with COVID-19 vaccines and vaccination data. At the end of 2021, 11.2 percent of these practices' 3.9 million patients had records of COVID-19 vaccination; 43.1 percent of clinics had no record of patients' COVID-19 vaccinations, but 93.4 percent of clinics had provided or recorded other routine vaccinations.

Primary Care Physician Leadership in Top Ranked US Hospitals.

This assessment of the "top hospitals" in the US according to 4 leading rankings reveals only 4 to 7% of represented CEOs are primary care physicians by training. Greater attention to leadership development from primary care residency through health system practice is needed to avoid diminishing primary care's critical role and salutary global benefits.

Impact of Service-Based Student Loan Repayment Program on the Primary Care Workforce.

PURPOSE: As the average level of medical education indebtedness rises, physicians look to programs such as Public Service Loan Forgiveness (PSLF) and National Health Service Corps (NHSC) to manage debt burden. Both represent service-dependent loan repayment programs, but the requirements and program outcomes diverge, and assessing the relative uptake of each program may help to inform health workforce policy decisions. We sought to describe variation in the composition of repayment program participant groups and measure relative impact on patient access to care. METHODS: In this bivariate analysis, we analyzed data from 10,677 respondents to the American Board of Family Medicine's National Graduate Survey to study differences in loan repayment program uptake as well as the unique participant demographics, scope of practice, and likelihood of practicing with a medically underserved or rural population in each program cohort. RESULTS: The rate of PSLF uptake tripled between 2016 and 2020, from 7% to 22% of early career family physicians, while NHSC uptake remained static at 4% to 5%. Family physicians reporting NHSC assistance were more likely than those reporting PSLF assistance to come from underrepresented groups, demonstrated a broader scope of practice, and were more likely to practice in rural areas (23.3% vs 10.8%) or whole-county Health Professional Shortage Areas (12.5% vs 3.7%) and with medically underserved populations (82.2% vs 24.2%). CONCLUSIONS: Although PSLF supports family physicians intending to work in public service, their peers who choose NHSC are much more likely to work in underserved settings. Our findings may prompt a review of the goals of service loan forgiveness programs with potential to better serve health workforce needs.

Comparison of associations of household-level and neighbourhood-level poverty markers with paediatric asthma care utilisation by race/ethnicity in an open cohort of community health centre patients.

OBJECTIVE: The objective of this research was to examine how different measurements of poverty (household-level and neighborhood-level) were associated with asthma care utilisation outcomes in a community health centre setting among Latino, non-Latino black and non-Latino white children. DESIGN, SETTING AND PARTICIPANTS: We used 2012-2017 electronic health record data of an open cohort of children aged <18 years with asthma from the OCHIN, Inc. network. Independent variables included household-level and neighborhood-level poverty using income as a percent of federal poverty level (FPL). Covariate-adjusted generalised estimating equations logistic and negative binomial regression were used to model three outcomes: (1) ≥2 asthma visits/year, (2) albuterol prescription orders and (3) prescription of inhaled corticosteroids over the total study period. RESULTS: The full sample (n=30 196) was 46% Latino, 26% non-Latino black, 31% aged 6-10 years at first clinic visit. Most patients had household FPL <100% (78%), yet more than half lived in a neighbourhood with >200% FPL (55%). Overall, neighbourhood poverty (<100% FPL) was associated with more asthma visits (covariate-adjusted OR 1.26, 95% CI 1.12 to 1.41), and living in a low-income neighbourhood (≥100% to <200% FPL) was associated with more albuterol prescriptions (covariate-adjusted rate ratio 1.07, 95% CI 1.02 to 1.13). When stratified by race/ethnicity, we saw differences in both directions in associations of household/neighbourhood income and care outcomes between groups. CONCLUSIONS: This study enhances understanding of measurements of race/ethnicity differences in asthma care utilisation by income, revealing different associations of living in low-income neighbourhoods and households for Latino, non-Latino white and non-Latino black children with asthma. This implies that markers of family and community poverty may both need to be considered when evaluating the association between economic status and healthcare utilisation. Tools to measure both kinds of poverty (family and community) may already exist within clinics, and can both be used to better tailor asthma care and reduce disparities in primary care safety net settings.

Quality of Care for Latinx Children with Asthma: Associations with Language Concordance and Continuity of Care.

BACKGROUND: Language concordance between Latinx patients and their clinicians has been shown to affect health outcomes. In addition, there is evidence that consistent continuity of care (COC) can improve health care outcomes. The relationship between language concordance and COC and their association with health equity in chronic disease is less clear. Our aim was to study the moderating effect of clinician and patient language concordance on the association between COC and asthma care quality in Latinx children. METHODS: We utilized an electronic health record dataset from a multistate network of community health centers to compare influenza vaccinations and inhaled steroid prescriptions, by ethnicity and language concordance groups overall and stratified by COC. RESULTS: We analyzed electronic health records for children with asthma (n = 38,442) age 3 to 17 years with ≥2 office visits between 2005 to 2017. Overall, 64% of children had low COC (defined as COC < 0.5) while 21% had high COC (defined as >0.75). All Latinx children had higher rates and odds of receiving influenza vaccination compared with non-Hispanic White children. In addition, Spanish-preferring Latinx children had higher rates and odds of being prescribed inhaled steroids while English-preferring Latinx children had lower odds (OR = 0.85 95%CI = 0.73,0.98) compared with non-Hispanic White children. CONCLUSION: Overall, Latinx children regardless of COC category or language concordance were more likely to receive the influenza vaccine. English-preferring Latinx children with persistent asthma received fewer inhaled steroid prescriptions compared with non-Hispanic White children. Panel chart review and seeing a practice partner might be one way to combat these inequities.

Maternity Access in Rural America: The Role of Family Physicians in Providing Access to Cesarean Sections.

INTRODUCTION: As an increasing number of rural hospitals close their maternity care units, many of the approximately 28 million reproductive-age women living in rural America do not have local access to obstetric services. We sought to describe the characteristics and distribution of cesarean section-providing family physicians who may provide critical services in maintaining obstetric access in rural hospitals. METHODS: Using a cross-sectional study design, we linked data from the 2017 to 2022 American Board of Family Medicine's Continuting Certification Questionnaire on provision of cesarean sections as primary surgeon and practice characteristics to geographic data. Logistic regression determined associations with provision of cesarean sections. RESULTS: Of 28,526 family physicians, 589 (2.1%) provided cesarean sections as primary surgeon. Those who provided cesarean sections were more likely to be male (odds ratio (OR) = 1.573, 95% confidence limits (CL) 1.246-1.986), and work in rural health clinics (OR = 2.157, CL 1.397-3.330), small rural counties (OR = 4.038, CL 1.887-8.642), and in counties without obstetrician/gynecologists (OR = 2.163, CL 1.440-3.250). DISCUSSION: Although few in number, family physicians who provide cesarean sections as primary surgeon disproportionately serve rural communities and counties without obstetrician/gynecologists, suggesting that they provide access to obstetric services in these communities. Policies that support family physician training in cesarean sections and facilitate credentialing of trained family physicians could reverse the trend of closing obstetric units in rural communities and reduce disparities in maternal and infant health outcomes.

How Do Family Physicians Document Patients' Social Needs in Electronic Health Records?

Social needs are critical determinants of patient health, but their capture in clinical records began recently. A representative survey of family physicians showed that 61% of respondents document social needs using notes, with fewer using diagnosis codes or electronic forms. This preference for unstructured documentation may make it difficult to connect patients across organizations or for policymakers and planners to identify geographic variation in needs.

The Association of Mobility, Social Deprivation, and Pediatric Primary Care Outcomes in Community Health Centers.

OBJECTIVE: To examine how social deprivation and residential mobility are associated with primary care use in children seeking care at community health centers (CHCs) overall and stratified by race and ethnicity. STUDY DESIGN: We used electronic health record open cohort data from 152 896 children receiving care from 15 U S CHCs belonging to the OCHIN network. Patients were aged 3-17 years, with ≥2 primary care visits during 2012-2017 and had geocoded address data. We used negative binomial regression to calculate adjusted rates of primary care encounters and influenza vaccinations relative to neighborhood-level social deprivation. RESULTS: Higher rates of clinic utilization were observed for children who always lived in highly deprived neighborhoods (RR = 1.11, 95% CI = 1.05-1.17) and those who moved from low-to-high deprivation neighborhoods (RR = 1.05, 95% CI = 1.01-1.09) experienced higher rates of CHC encounters compared with children who always lived in the low-deprivation neighborhoods. This trend was similar for influenza vaccinations. When analyses were stratified by race and ethnicity, we found these relationships were similar for Latino children and non-Latino White children who always lived in highly deprived neighborhoods. Residential mobility was associated with lower rates of primary care. CONCLUSIONS: These findings suggest that children living in or moving to neighborhoods with high levels of social deprivation used more primary care CHC services than children who lived in areas with low deprivation, but moving itself was associated with less care. Clinician and delivery system awareness of patient mobility and its impacts are important to addressing equity in primary care.

Interoperability among hospitals treating populations that have been marginalized.

OBJECTIVE: To test whether differences in hospital interoperability are related to the extent to which hospitals treat groups that have been economically and socially marginalized. DATA SOURCES AND STUDY SETTING: Data on 2393 non-federal acute care hospitals in the United States from the American Hospital Association Information Technology Supplement fielded in 2021, the 2019 Medicare Cost Report, and the 2019 Social Deprivation Index. STUDY DESIGN: Cross-sectional analysis. DATA COLLECTION/EXTRACTION METHODS: We identified five proxy measures related to marginalization and assessed the relationship between those measures and the likelihood that hospitals engaged in all four domains of interoperable information exchange and participated in national interoperability networks in cross-sectional analysis. PRINCIPAL FINDINGS: In unadjusted analysis, hospitals that treated patients from zip codes with high social deprivation were 33% less likely to engage in interoperable exchange (Relative Risk = 0.67, 95% CI: 0.58-0.76) and 24% less likely to participate in a national network than all other hospitals (RR = 0.76; 95% CI: 0.66-0.87). Critical Access Hospitals (CAH) were 24 percent less likely to engage in interoperable exchange (RR = 0.76; 95% CI: 0.69-0.83) but not less likely to participate in a national network (RR = 0.97; 95% CI: 0.88-1.06). No difference was detected for 2 measures (high Disproportionate Share Hospital percentage and Medicaid case mix) while 1 was associated with a greater likelihood to engage (high uncompensated care burden). The association between social deprivation and interoperable exchange persisted in an analysis examining metropolitan and rural areas separately and in adjusted analyses accounting for hospital characteristics. CONCLUSIONS: Hospitals that treat patients from areas with high social deprivation were less likely to engage in interoperable exchange than other hospitals, but other measures were not associated with lower interoperability. The use of area deprivation data may be important to monitor and address hospital clinical data interoperability disparities to avoid related health care disparities.
