Abstract: Objective To comprehensively assess and analyze the medical quality index,to grasp the overall trend of medical quality level,and provide the basis for the improvement of medical quality and service ability. Methods On the basis of literature analysis,the number of emergency visits and discharges,surgical cases,bed utilization rate,bed turns,average hospital stay,diagnosis coincidence rate between admission and discharge,cure and improvement rate,rescue achievement ratio,average hospitalization cost,proportion of drug cost,etc.medical indicators were made to evaluation system.The comprehensive index method were used to evaluate the medical quality of the last 8 years,and Rank sum ratio(RSR) method was used to grade the development of medical quality. Results The medical quality comprehensive index rose gradually in 2008-2015,and the comprehensive index in 2015 and 2014 was 1.96 times and 1.96 times that of 2008,respectively.According to the sort of RSR values and step results,medical quality was low in 2008-2010 and better in 2014-2015,the medical quality in the rest of years were in the medium level. Conclusion s The medical quality are improved in 2008-2015.On the basis of ensuring the medical quality and medical safety,a variety of forms are carried out to reduce the workload,improve medical efficiency and technical content,so as to optimize quality and enhance the overall strength of hospital.RSR method and comprehensive index method,considering the importance of medical evaluation index,can scientifically and objectively reflect the hospital medical quality,increase the efficiency of the analysis and make the evaluation more scientific and reasonable.
