Abstract

BACKGROUND: The impact of human immunodeficiency virus (HIV) infection on outcomes following common emergency general surgery procedures has not been evaluated since the widespread introduction of highly active antiretroviral therapy. METHODS: A retrospective cohort study was conducted using the Nationwide Inpatient Sample. Records of patients who underwent laparoscopic or open appendectomy, cholecystectomy, or colon resection after emergency admission from 2004 to 2011 were obtained. Outcomes analyzed included in-hospital mortality, length of stay, total charges, and selected postoperative complications. Patients were divided among three groups, HIV-negative controls, asymptomatic HIV-positive patients, and symptomatic HIV/acquired immune deficiency syndrome (AIDS) patients. Data were analyzed using χ and multivariable regression with propensity score matching among the three groups, with p value less than 0.05 significant. RESULTS: There were 974,588 patients identified, of which 1,489 were HIV-positive and 1,633 were HIV/AIDS-positive. The HIV/AIDS patients were more likely to die during their hospital stay than HIV-negative patients (4.4% vs. 1.6%, adjusted odds ratio, 3.53; 95% confidence interval [CI], 2.67-4.07; p < 0.001). The HIV/AIDS patients had longer hospital stays (7 days vs. 3 days; adjusted difference, 3.66 days; 95% CI, 3.53-4.00; p < 0.001) and higher median total charges than HIV-negative patients (US $47,714 vs. US $28,405; adjusted difference, US $15,264; 95% CI, US $13,905-US $16,623; p < 0.001). The HIV/AIDS patients also had significantly increased odds of certain postoperative complications, including sepsis, septic shock, pneumonia, urinary tract infection, acute renal failure and need for transfusion (p < 0.05 for each). Differences persisted irrespective of case complexity and over the study period. Asymptomatic HIV-positive patients had outcomes similar to HIV-negative patients. CONCLUSION: The HIV/AIDS patients have a greater risk of death, infectious, and noninfectious complications after emergency surgery regardless of operative complexity and despite advanced highly active antiretroviral therapy. Patients who have not developed advanced disease, however, have similar outcomes to HIV-negative patients. LEVEL OF EVIDENCE: Prognostic and epidemiologic study, level III.
