ABSTRACT
BACKGROUND: Patient safety is an essential element in the quality of healthcare, and a clear knowledge of its culture in healthcare organizations will lead to both improved healthcare and patient safety. The aim of this study was to assess the patient safety culture at Islamic Azad University hospitals in Tehran, Iran, in 2013. METHODS: This cross-sectional study was conducted on clinical and diagnostic staff in all Islamic Azad University hospitals in Tehran in June 2013. The international "Hospital Survey on Patient Safety Culture" questionnaire was used as the measurement tool. RESULTS: In these hospitals, the overall positive score of patient safety culture was 35%. "Teamwork within units" (48% positive) was evaluated as reflecting the most knowledge of the aspects of patient safety culture, and "non-punitive response to error" (12% positive) was evaluated as reflecting the least knowledge of the aspects of patient safety culture. CONCLUSION: The patient safety culture in the hospitals that were studied should be improved. This goal could be achieved by reinforcing the basics of patient safety culture by teaching the staff members about the aspects of a positive patient safety culture and encouraging them to incorporate these aspects in their day-to-day activities.
ABSTRACT
BACKGROUND: One of the significant dangers that threaten people's lives is the increased risk of accidents. Annually, more than 1.3 million people die around the world as a result of accidents, and it has been estimated that approximately 300 deaths occur daily due to traffic accidents in the world with more than 50% of that number being people who were not even passengers in the cars. The aim of this study was to examine traffic accidents in Tehran and forecast the number of future accidents using a time-series model. METHODS: The study was a cross-sectional study that was conducted in 2011. The sample population was all traffic accidents that caused death and physical injuries in Tehran in 2010 and 2011, as registered in the Tehran Emergency ward. The present study used Minitab 15 software to provide a description of accidents in Tehran for the specified time period as well as those that occurred during April 2012. RESULTS: The results indicated that the average number of daily traffic accidents in Tehran in 2010 was 187 with a standard deviation of 83.6. In 2011, there was an average of 180 daily traffic accidents with a standard deviation of 39.5. One-way analysis of variance indicated that the average number of accidents in the city was different for different months of the year (P < 0.05). Most of the accidents occurred in March, July, August, and September. Thus, more accidents occurred in the summer than in the other seasons. The number of accidents was predicted based on an auto-regressive, moving average (ARMA) for April 2012. The number of accidents displayed a seasonal trend. The prediction of the number of accidents in the city during April of 2012 indicated that a total of 4,459 accidents would occur with mean of 149 accidents per day during these three months. CONCLUSION: The number of accidents in Tehran displayed a seasonal trend, and the number of accidents was different for different seasons of the year.
