Abstract Purpose Sepsis disproportionately affects patients in rural and socially vulnerable communities. A promising strategy to address this disparity is provider‐to‐provider emergency department (ED)‐based telehealth consultation (tele‐ED). The objective of this study was to determine if county‐level social vulnerability index (SVI) was associated with tele‐ED use for sepsis and, if so, which SVI elements were most strongly associated. Methods We used data from the TELEmedicine as a Virtual Intervention for Sepsis in Rural Emergency Department study. The primary exposures were SVI aggregate and component scores. We used multivariable generalized estimating equations to model the association between SVI and tele‐ED use. Findings Our study cohort included 1191 patients treated in 23 Midwestern rural EDs between August 2016 and June 2019, of whom 326 (27.4%) were treated with tele‐ED. Providers in counties with a high SVI were less likely to use tele‐ED (adjusted odds ratio [aOR] = 0.51, 95% confidence interval [CI] 0.31‒0.87), an effect principally attributable to the housing type and transportation component of SVI (aOR = 0.44, 95% CI 0.22–0.89). Providers who treated fewer sepsis patients (1‒10 vs. 31+ over study period) and therefore may have been less experienced in sepsis care, were more likely to activate tele‐ED (aOR = 3.91, 95% CI 2.08‒7.38). Conclusions Tele‐ED use for sepsis was lower in socially vulnerable counties and higher among providers who treated fewer sepsis patients. These findings suggest that while tele‐ED increases access to specialized care, it may not completely ameliorate sepsis disparities due to its less frequent use in socially vulnerable communities.

AbstractPurposeTo assess differences in Patient Aligned Care Team (PACT) performance between rural and urban primary care clinics within the Veterans Health Administration (VHA).MethodsAn Explanatory Sequential Mixed Methods design was conducted using VHA administrative data to assess performance of a national sample of 891 VHA primary care clinics. Generalized Estimating Equations with repeated measures were used to estimate associations between rurality and process‐oriented endpoints including: chronic disease management through telehealth; use of telephone visits, group visits or secured messaging; same‐day access; continuity with primary care provider; and postdischarge follow‐up. Qualitative data collected during on‐site visits with 5 clinics were used to provide insights into PACT processes from the perspectives of staff in rural and urban clinics.FindingsAfter adjusting for patient‐ and practice‐level characteristics, clinics located in large rural or small/isolated rural areas demonstrated difficulty enhancing access through use of telephone visits, group visits, or secured messaging and completing postdischarge follow‐up calls, compared to urban clinics. Qualitative analysis indicated that staff from both rural and urban clinics reported similar barriers implementing these PACT processes. Both patient and staff behaviors and preferences impact implementation of these processes. Distance to care and access to high‐speed Internet were also reported as barriers.ConclusionsThis study contributes to the understanding of PACT performance in rural settings by highlighting ways contextual and behavioral factors relate to performance. Increasing implementation of patient‐centered medical home (PCMH) models, such as PACT, will require additional attention to the complex relationships between the practice and surrounding context.
