Investigtions the functional indicators change due to implementation information system in Sina hospital

A Hospital information system is an essential technology for health care، which can lead to improvement of hospital performance indicators، if it used correctly. The goal of this study is to investigate the functional indicators change due to implementation information system in Sina hospital. This Descriptive-Analytical study was conducted in 16 unist of Sina hospital in 2012. The data gathering tool was designed form all information related to hospital information systems and hospital bed indexes were gatherd from the information stored in the data and statistic management unit. Data analysis was conducted by descriptive statistics and two-sample t-tests. MI of occupied bed one day before establishment of hospital information system was 5567. 81±3617. 04 days and a day after decreased to 5066. 37±2646. 62 days. MI of bed occupancy before establishment of hospital information system was 74. 43±11. 44 percent and after that، increased to 76. 5 ± 14. 62 percent. Average index of length of hospitation before Establishment Hospital information system was 8. 31± 6. 51 days and after decreased to 6. 46 ±3. 70 days. Bed turnover interval before establishment of hospital information systems was 1. 12 ± 1. 02 and after increased to 1064 ±1. 42 days. There was a significant relationship between bed turnover interval index and the hospital information system (p=0/03). Due to the lack of the relation between hospital information systems and performance indicators for hospitals; it appears that hospital information systems in hospitals could not be dramatically effective in improving the indicators.
