|Title||The Impact of Resident Duty-Hour Limits on Sleep Quality: A Cross-sectional Study|
|Title in Arabic||تأثير عدد ساعات العمل على جودة النوم لدى الأطباء المقيمين: دراسة مسحية|
Objective: Resident physicians are particularly prone to sleep disturbance due to long shift hours and excessive workload. Despite the numerous measures undertaken to improve their well-being, it’s still unknown if limiting the work shift duration would improve sleep quality. Methods: A self-reported questionnaire was used to obtain data about sleep quality, anxiety and depression using PSQI and PHQ-4 scales, respectively. Using data from previous study, we compared those parameters before and after the implementation of duty hour reduction across several specialties in a tertiary center. Furthermore, we investigated residents’ life satisfaction using SWLS scale. Results: 180 residents filled the questionnaire (median age: 26.5 years). Males reported higher rates of poor sleep quality while females had higher rates of anxiety and depression. Decreasing the duration of on-call shifts from 32 to 24 hours decreased the prevalence of poor sleep quality from 91.5% to 83.2% (p: 0.038), and smoking rates decreased from 30.4 to 12.5% (p: <0.0001). More than 6 on-calls per month was associated with poorer quality of sleep. Night float shifts decreased rates of moderate and severe PHQ-4 scores significantly (p: <0.001). In addition, 63.3% of residents were satisfied with life. Life satisfaction was associated with enhanced sleep quality and lower PHQ-4 scores (p: 0.007 and <0.0001, respectively). Conclusions: Optimizing shift scheduling and duration can positively influence rates of sleep quality, anxiety, depression, and smoking rates. More interventions should be tackled along with duty hour limits to optimize residents’ satisfaction with life.
