Providing safe, efficient, and quality services to all people is critical for achieving effective universal health coverage and the health-related sustainable development goals (SDGs) and in particular SDG 3.8. Medical error as a main challenge of delivery systems is a main influential factor on patient safety and quality of health care services. Investigating factors influencing on medical errors can help to improve quality patient safety. This study aimed to investigate the relationship between several contributed factors on incidence of medical errors in East Azarbaijan province, Iran.
We conducted a cross-sectional study, resulting in 10700 voluntary reporting of medical errors by medical staff working in all types of hospitals including public and non-educational, educational, private, military, charity and social security hospitals. Poisson regression was used for data analysis.
The most frequency of medical errors reported by 41 studied hospitals was related to educational public hospitals, medical errors with no harm in the fall and the least frequency was related to non-educational public hospitals and surgical errors in the spring season. As the results show, spring and summer have a significantly lower incidence of medical error compared to winter (P < 0.001). Also, the incidence of medical error in the morning shift was significantly higher than the night shift (P < 0.001). According to the results, the incidence of errors with the consequence of near miss, no harm was significantly higher than the sentinel event error.
The results of the present study showed that the factors, different season, work shift, medical error type, medical error intensity and hospital type have a significant relationship with the incidence of medical error.
