摘要:BACKGROUND: Providing the high-quality services in hospitals depends on to minimize conflict between all members within a health team. This study aimed to identify the causes of conflicts experienced by clinical and administrative staff in hospitals. METHODS: A cross-sectional study was carried out in 2018. The sample included 320 clinical and administrative staff from six hospitals affiliated to Ardabil University of Medical Sciences that were selected using two-step clustering sampling method. Data collection was accomplished by self-administered questionnaires. Descriptive statistics, t -test, and ANOVA were used for data analysis. RESULTS: Total conflict score revealed that clinical staff had higher levels of perceived conflict than administrative staff. In terms of organizational position, the study results showed a significant difference in the reported conflict between nurse groups and other groups (physicians and paramedical, administrative, financial, and logistic staff). The most important causes of conflict in the viewpoint of clinical staff were organizational and job characteristics (3.54 ± 1.28), poor management (3.51 ± 1.12), and inefficient communication system (3.42 ± 1.33). For administrative staff, on the other hand, poor management (3.18 ± 1.33), inefficient communication system (3.17 ± 1.36), and attitudes and perceptions (3.06 ± 1.41) were shown to be paramount factors. CONCLUSION: Clinical and administrative staff of hospitals are like parts of a train track. The irrational relationship between them will result in distortion and lower quality of services. Therefore, effective strategies to decrease staffs' experience of conflict need to be developed. This might create a healthier and more productive work environment which positively affects the care quality.
