OBJECTIVE: To calculate additional hospital stay due to specific cross infection. METHODS: Cases and controls study; matched by age +/- 2 years, sex, specialty in which were taken care, diagnosis, surgical procedure and hospitalization stay, between July 2005-June 2006. ANALYSIS: t test, chi(2) to calculate death risk, Kaplan-Meier analysis to calculate survival, Hosmer-Lemeshow test to know the contribution of cross infection for additional hospital stay due to cross infection (AHSDCI). RESULTS: We identified 851 patients with 1347 cross infection in 16 528 discharges. We could match 677. The cases stayed 25.42 days and the controls 13.29 (p < 0.01). The death risk for the cases was 5.8 (CI 95 % = 3.7-8.6, p < 0.01), four weeks survival 55.3 % for cases and 79.2 % for the controls. The AHSDCI for pneumonia was 10.39 days, urinary-tract-infection 6.28, bacteremia 8.92, vascular-catheter-related infection 3.31, surgical site infections 7.42, and skin and soft-tissue-infection 3.31 (p < 0.05). CONCLUSIONS: We used a multivariate model fitted to patient's gravity and complexity to extract the proportion days of AHSDCI of each cross infection.
