Popis: | 107 Background and purpose:Hospital-acquired methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infection (BSI) is associated with an excess mortality, prolonged hospital stay, and extra medical cost, compared with hospital-acquired methicillin-sensitive S. aureus (MSSA) BSI. The aims of our study to compare the risk of new-onset long-term hemodialysis and ventilator dependence between MRSA BSI and MSSA BSI. Method:This is a retrospective cohort study of all inpatients had healthcare-associated infections (HAI) with S. aureus BSIs at Taichung Veterans General Hospital (Taichung, Taiwan), between 1 January 2010 and 31 December 2017. We compared MSSA and MRSA BSIs for medical cost, mortality, new-onset long-term hemodialysis and new-onset ventilator dependence. We used Cox proportional hazard regression to adjust for the effects of confounding factors. Result:There were 147 MRSA BSIs and 81 MSSA BSIs during the study period. The mean medical expenditure were NT$570,555 for MRSA and NT$348,887 for MSSA (p=0.001). In comparison with patients with MSSA BSI, patients with MRSI BSI had an increase in risk of mortality (hazard ratio [HR] 1.67, 95% CI 0.94-2.95), new-onset dialysis-dependence (HR 1.64, 95% CI 0.38-7.14) and new-onset ventilator dependence (HR 1.32, 95% CI 0.26-6.73) after adjusting for severity of sepsis and the comorbidities. Conclusion:Patients with MRSA BSI tend to have poorer outcomes, in term of both acute mortality and chronic dialysis/ventilator-dependence. Our results highlight the importance of hospital-acquired MRSA infection control. |
