MRSA cause blood, skin, joints, respiratory, soft tissue and other infections. The purpose of this study was to investigate survival analysis of patients with Methicillin-resistant Staphylococcus aureus infection, this was a study using survival analysis on 284 patients with MRSA infection. We use Kaplan-Meier Curve to calculated survival time in 30 days, hazard ratios for certain variables were estimated using the Cox proportional hazards model. The findings from the Kaplan-Meier analysis of the results of the MRSA survivors indicated 1-day cumulative survival rate 98.2%, 7-day cumulative survival rate 89.1%, 10-day cumulative survival rate 83.1%, 20-day cumulative survival rate 73.9%, 30-day cumulative survival rate 63.4%. The result from Cox proportion hazard model analysis of prognostic independent factor were presented in the following: age, bacteremia, pneumonia, cirrhosis, chronic obstructive pulmonry disease and leukemia. Applying the Cox proportional hazards model to quickly diagnose and implement efficient infection control programs to reduce the medical costs.
