Question What is the association between health insurance status and rates and outcomes of unplanned surgery for access-sensitive conditions (abdominal aortic aneurysm, ventral hernia, and colon cancer)?
Findings In this cross-sectional study of 146 609 patients younger than 65 years, compared with patients with private insurance, uninsured patients had more than twice the rate of unplanned surgery (73% vs 33%), higher rates of inpatient mortality and postoperative complications, and longer hospital stays.
Meaning Findings of this study suggest that uninsured patients more often undergo unplanned surgery for conditions that can be treated electively, with worse outcomes and longer hospital stays.
Abstract
Importance Access-sensitive surgical conditions, such as abdominal aortic aneurysm, ventral hernia, and colon cancer, are ideally treated with elective surgery, but when left untreated have a natural history requiring an unplanned operation. Patients’ health insurance status may be a barrier to receiving timely elective care, which may be associated with higher rates of unplanned surgery and worse outcomes.
Objective To evaluate the association between patients’ insurance status and rates of unplanned surgery for these 3 access-sensitive surgical conditions and postoperative outcomes.
Design, Setting, and Participants This cross-sectional cohort study examined a geographically broad patient sample from the Healthcare Cost and Utilization Project State Inpatient Databases, including data from 8 states (Arizona, Colorado, Florida, Kentucky, Maryland, North Carolina, Washington, and Wisconsin). Participants were younger than 65 years who underwent abdominal aortic aneurysm repair, ventral hernia repair, or colectomy for colon cancer between 2016 and 2020. Patients were stratified into groups by insurance status. Data were analyzed from June 1 to July 1, 2023.
Exposure Health insurance status (private insurance, Medicaid, or no insurance).
Main Outcomes and Measures The primary outcome was the rate of unplanned surgery for these 3 access-sensitive conditions. Secondary outcomes were rates of postoperative outcomes including inpatient mortality, any hospital complications, serious complications (a complication with a hospital length of stay longer than the 75th percentile for that procedure), and hospital length of stay.
Results The study included 146 609 patients (mean [SD] age, 50.9 [10.3] years; 73 871 females [50.4%]). A total of 89 018 patients (60.7%) underwent elective surgery while 57 591 (39.3%) underwent unplanned surgery. Unplanned surgery rates varied significantly across insurance types (33.14% for patients with private insurance, 51.46% for those with Medicaid, and 72.60% for those without insurance; P < .001). Compared with patients with private insurance, patients without insurance had higher rates of inpatient mortality (1.29% [95% CI, 1.04%-1.54%] vs 0.61% [0.57%-0.66%]; P < .001), higher rates of any complications (19.19% [95% CI, 18.33%-20.05%] vs 12.27% [95% CI, 12.07%-12.47%]; P < .001), and longer hospital stays (7.27 [95% CI, 7.09-7.44] days vs 5.56 [95% CI, 5.53-5.60] days, P < .001).
Conclusions and Relevance Findings of this cohort study suggest that uninsured patients more often undergo unplanned surgery for conditions that can be treated electively, with worse outcomes and longer hospital stays compared with their counterparts with private health insurance. As efforts are made to improve insurance coverage, tracking elective vs unplanned surgery rates for access-sensitive surgical conditions may be a useful measure to assess progress.
