RESUMEN
BACKGROUND: Elderly patients are thought to tolerate surgical complications poorly because of low physiologic reserve. The purpose of the study was to evaluate the differential effects of surgical harm in patients over 80 years old. METHODS: Three years of data from a harm-reduction campaign were used to identify inpatient surgeries performed on patients older than 50. The rates of harm, death, cost, and length of stay (LOS) were analyzed using SPSS 21 (IBM, New York, NY). RESULTS: A total of 22,710 patients were identified. Rates of harm and mortality increased with increasing age. Harmed patients over age 80 had increased mortality (9.5% vs 7%), but lower cost, intensive care unit days, and LOS versus those aged 50 to 80. Linear regression showed increased cost with harm ($24,000) and decreased cost with age above 80 (-$7,000). CONCLUSIONS: In the elderly surgical population, there is more harm and harm events are associated with higher mortality rates, but less additional cost and LOS. Differing goals or aggressiveness of care may explain cost avoidance in the elderly.
