Evaluating the Swedish Occupational Fatigue Inventory (SOFI) Among Providers in a Pediatric Emergency Department

Year: 2026

Type: article

Abstract: OCCUPATIONAL APPLICATIONSThis study evaluated the Swedish Occupational Fatigue Inventory (SOFI) and its revised versions among pediatric emergency department providers (e.g., attendings, fellows, advanced practice providers). Findings show that the original SOFI is a valid tool for measuring occupational fatigue, but a shortened version—excluding physical exertion items—offers better fit and usability. Adding items from the Center for Epidemiologic Studies Depression Scale (CES-D) did not enhance fatigue measurement. For practitioners, the reduced SOFI provides a practical, reliable way to assess fatigue in physicians and advanced practice providers in fast-paced clinical environments. Its brevity supports frequent use without burdening staff, enabling timely identification of fatigue-related risks. This tool can inform interventions such as shift redesign, break scheduling, and technology usability testing, ultimately supporting clinician wellness and patient safety.
