Background: Human behavior is recognized as the main factor in the occurrence of accidents (70-90 percent), with human personality and problem solving ability as two related factors in the occurrence of medical errors (annually 42.7 million in the world). The objectives of this study were to investigate the relationship between personality factors, problem solving ability and medical errors.
Material and methods: This study was a questionnaire case control study. Information on 49 members of medical and nursing staff with medical errors (case group) and 46 without medical errors (control group) were analyzed. To collect the data, two Heppner problem solving questionnaires and the NEO-Five Factor Inventory were used, which were completed by the study population.
Results: The results illustrate that individuals without medical errors showed higher scores in contentiousness, extraversion and agreeableness and lower scores in neuroticism than those with medical errors. Individuals without medical errors also showed higher scores in problem solving ability scales than those with medical errors.
Conclusion: Results of this study, suggest that personality factors and problem solving ability are related to medical errors and it may be possible for hospital authorities to use this knowledge when selecting capable medical staff.
