Therefore, this study aimed to investigate the prevalence and clinical and psychological outcomes of DBs among physicians and nurses in the emergency departments of teaching hospitals in Iran.<br> <strong>Materials & Methods</strong>: In this cross-sectional study, 105 participants, including 33 physicians and 72 nurses working in the emergency departments of two teaching hospitals affiliated to Alborz University of Medical Sciences, who were selected using a convenience sampling method during May-June 2020. They filled out a demographic form and Rosenstein and O&rsquo;Daniel&rsquo;s DB scale. The data were analyzed in SPSS software version 20 using descriptive statistics and independent t-test.&nbsp;<br> <strong>Results</strong>: The DBs were prevalent in the emergency departments. All respondents reported that they had witnessed DBs in their hospitals. The primary barrier to reporting was the feeling that nothing ever changes (47.6%). The majority of physicians and nurses (81%) indicated that DBs had a significant impact on patient outcomes. There was a significant difference between nurses&rsquo; and physicians&rsquo; responses to the seriousness of nurse DBs (t=-13.05, P<0.001) and the seriousness of the impact of DBs on patient outcomes (t=-5.75, P<0.001).<br> <strong>Conclusion</strong>: Addressing DBs in the emergency departments requires practical and effective educational interventions for the personnel, increasing awareness of hospital managers, developing policies and guidelines, and monitoring their implementation.&nbsp;<br> &nbsp;</div> Disruptive behavior (DB) disorder, Emergency treatment, Nursing care, Patient safety 103 112 http://cpr.mazums.ac.ir/browse.php?a_code=A-10-182-1&slc_lang=en&sid=1 Roohangiz Norouzinia norouzinia.r@gmail.com 10031947532846001989 10031947532846001989 No Social Determinants of Health Research Center, Alborz University of Medical Sciences, Karaj, Iran.
