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. KEYWORDS health equity, health information exchange, health system, hospitals, interoperability What is known on this topic * Several hospital characteristics reflecting smaller scale or reduced resources have been shown to relate to lower rates of hospital engagement in the interoperable exchange of health information, an important policy goal. * Numerous proxy measures exist for describing the patient populations hospitals treat, and measures are not closely correlated, complicating descriptions of the extent that hospitals treat populations that have been marginalized. What this study adds * Only one of five proxy measures of the extent to which hospitals treat populations that have been marginalized--the area social deprivation index--was associated with differences in hospital interoperability. * Differences by social deprivation index persist when separately examining rural and urban hospitals and adjusted analysis, indicating this metric is capturing information beyond geographic divides., 1 | INTRODUCTION Interoperable exchange--the sharing and integration of health information between organizations--provides important benefits to patients. (1) While hospital engagement in interoperable exchange and participation in national networks has [...]
