Abstract

The Veterans Health Administration (VHA) reports multiple indicators of hospital surgical performance, including hospital risk-standardized 30-day readmission rates (RSRRs). Currently, most routinely reported measures do not include readmissions that occur outside VHA hospitals. The impact of readmissions outside the VHA on hospital RSRR is not known. To measure the impact of including non-VHA readmissions on VHA hospital performance rankings for 30-day readmission. This retrospective cohort study included patients aged at least 65 years from 2013 to 2019 from the Veterans Affairs Surgical Quality Improvement Program linked to patient-level data from the VHA and Medicare. Data were limited to patients with VHA and Medicare enrollment during the year prior to surgery. Data were analyzed from November 2023 through July 2024. The main outcome was readmissions to acute care VHA or non-VHA hospitals within 30 days of discharge. VHA hospital-level RSRRs were estimated using separate generalized linear mixed-effects risk adjustment models that alternatively included VHA-only or VHA plus non-VHA readmissions. VHA hospitals were then stratified into quintiles based on RSRRs derived using VHA-only or VHA plus non-VHA readmissions. Changes in hospital performance quintiles with the addition of non-VHA readmissions were calculated, and characteristics of VHA hospitals most impacted by including non-VHA readmissions were evaluated. The eligible cohort included 108 265 patients (mean [SD] age, 72.2 [6.5] years; 105 661 [97.6%] male) who underwent surgery in 104 VHA hospitals. The combined readmission rate was 14.0%. The proportion of readmissions occurring outside the VHA ranged from 0% to 55.3% across the 104 VHA hospitals (median, 20.9%). Using VHA and non-VHA readmissions, 24 VHA hospitals (23.1%) improved performance and 23 hospitals (22.1%) worsened performance, defined as a decrease or increase, respectively, of 1 or more RSRR quintiles. Improvements in hospital performance rank were associated with larger surgical volume (-7.48; 95% CI, -11.33 to 03.64; P < .001), urban location, greater surgical complexity (-9.86; 95% CI, -16.61 to -3.11; P = .005), and lower proportion of readmissions outside the VHA (-8.15; 95% CI, -12.75 to -3.55; P < .001). In this cohort study, VHA hospitals whose readmission performance metric improved by including non-VHA readmissions had higher patient volume, higher complexity, and lower proportion of care outside the VHA. Thus, improving continuity of care may have a paradoxical effect of worsening VHA performance metrics.
