Objective: Dual-Eligible beneficiaries are patients who receive both Medicare and Medicaid. They represent a vulnerable population with high resource utilization and are more likely to experience negative social determinants of health. The impact of socioeconomic status following emergency laparotomy (EL), a procedure with known higher acuity of care, has not been well-examined. This study sought to better characterize perioperative outcomes after EL in Dual-Eligibles compared to non-Dual-Eligible patients.
Design: National Inpatient Sample (NIS) retrospectively analyzed over a 10-year period. Analysis done using Chi-Square and T-Test. Multivariable logistic regressions used to control for gender, age, and race.
Patients: Adults undergoing EL; including small and large bowel resection, perforated ulcer.
Main Outcome Measures: Complications, including infection and inpatient mortality, length of stay (LOS) and discharge disposition.
Results: 238,327 patients met inclusion criteria. Dual-Eligibles comprised 10.1% of patients and were on average younger (68.1 years) than Medicare (73.7) but older than Medicaid (44.4), Private (50.3), and Self-Pay (42.3), p<0.0001. After adjusting for confounders, Dual-Eligibles had significantly longer mean LOS (15.9 days) compared to Medicare (14.3), Medicaid (13.9), Private (10.7) and Self-Pay (9.9), p<0.0001. Additionally, Dual-Eligibles had significantly higher inpatient mortality and were less often discharged home compared to Medicare, Medicaid, Private, and Self-Pay (Table).
Conclusions: Dual-Eligibles undergoing EL had longer LOS than all other patient groups, higher inpatient mortality and were less likely to be discharged home. These worse outcomes in Dual-Eligibles signal a need for targeted perioperative interventions of modifiable risk factors in order to lessen these disparities.
