Impact of Fatigue on Emergency Physicians’ Decision-making for Computed Tomographic Scan Requests and Inpatient Referrals: An Observational Study from a Tertiary Care Medical Center of the Sultanate of Oman

OBJECTIVE: Multiple factors contribute to decision fatigue experienced by emergency physicians (EPs). This study examines the association between decision fatigue and the frequency of computed tomographic (CT) scan requests and inpatient referrals among EPs. METHODS: This retrospective database analysis was done for 3 months. Scans and inpatient referral requests were coded and analyzed to assess the impact of physician fatigue on decision-making. Subsequently, the outcomes were evaluated. RESULTS: The majority of patients (n = 481; 51.1%) had a CT brain request. Among these requests, the morning shift (8:00 a.m.–3:00 p.m.) accounted for the highest number (n = 400; 42.5%), followed by the evening shift (3:00–11:00 p.m.) (n = 345; 36.7%). Approximately one-third of the patients (n = 301; 31.9%) had positive CT scan findings. Statistical analysis comparing the first and the second halves of each shift did not reveal significant variations in the percentage of negative CT results (p-value: 0.093). Inpatient referral was necessary for over half of the patients (n = 1,048; 52.7%), and the majority of these referrals (n = 778; 74.2%) were deemed necessary for treatment under various surgical or medical specialties. There was a statistically significant difference in the proportion of negative inpatient referrals between the first and the second halves of the afternoon shift (p-value < 0.001). CONCLUSIONS: Fatigue among EPs was observed, leading to more frequent consultations without inpatient admission during the latter half of the afternoon shift. However, the study found no significant impact of decision fatigue on CT scan decision-making. HOW TO CITE THIS ARTICLE: Al-Arimi AH, Hazra D, Al-Alawi AKA.
