Hospital ownership: a risk factor for nosocomial infection rates?

摘要

BackgroundIn some countries, a relationship between hospital ownership and the occurrence of healthcare-associated infection (HCAI) rates has been described. AimTo investigate the association between hospital ownership and occurrence of HCAI in Germany. MethodsFive different components of the German national nosocomial infection surveillance system were analysed with regard to the influence of hospital ownership in the period 2014–2016. Endpoints included ventilator-associated pneumonia, central-venous-catheter-associated bloodstream infections, urinary-catheter-associated urinary tract infections, surgical site infections (SSI) following hip prosthesis and colon surgery, meticillin-resistantStaphylococcus aureus(MRSA),Clostridium difficileinfections (CDI) and hand rub consumption per 1000 patient-days. Three hospital ownership types (public, non-profit and private) were analysed using univariate and multi-variate methods. FindingsThe distribution of hospitals according to the three ownership types was similar in all components. In total, 661 intensive care units (ICUs), 149 departments performing colon procedures, and 349 departments performing hip prosthesis were included. In addition, 568 hospitals provided their MRSA rates and 236 provided their CDI rates, and 1833 ICUs and 12,934 non-ICUs provided their hand rub consumption data. In general, the differences between the hospital types were rather small and not significant for the ICUs. In the multi-variate analysis, public hospitals had a lower SSI rate following hip prosthesis (odds ratio 0.80, 95% confidence interval 0.65–0.99). ConclusionHospital ownership was not found to have a major influence on the incidence of HCAI in Germany.
