Sleep Quality and Related Factors in Medical Residents

Abstract

Introduction: The aim of this study was to assess the sleep quality and daytime sleepiness of resident doctors, to compare the sleep quality between surgical and medical branch residents and to examine effects of working hours, number of duties, clinical branches and some other daily habits on the sleep quality of resident doctors in a hospital in Turkey. Methods: A survey was conducted to gather data on (i) demographics, lifestyle and daily habits as well as to determine (ii) Epworth sleepiness scale (ESS) score and (iii) Pittsburgh sleep quality index (PSQI) scores of the participants. Data collection was based on the use of a self-administered questionnaire. Results: Of 138 resident doctors, 45.7% were classified as having good sleep quality based on a cut-off score of 5 in PSQI. The mean ESS and PSQI scores were 6.59 ±3.92 and 6.30 ±3.22, respectively. Significantly positive correlations were found between Epworth score and the number of night duties (p=0.010), working hours per week (p=0.006), total cigarettes per day (p=0.033), and daily tea consumption (p=0.013). Also, there were statistically significant positive correlations between PSQI scores and the number of night duties (p<0.001), working hours per week (p=0.007), total cigarettes per day (p=0.013) and daily coffee consumption (p=0.002). Surgical residents had significantly poor sleep quality (p=0.015). ESS score was higher in female residents and surgical residents, with a significant difference in these two sub-groups (p=0.018, p=0.008 respectively). Conclusions: Sleep quality and daytime sleepiness of the resident doctors were closely related to lifestyle factors including working hours, number of night duties and branch of residency as well as to certain demographic factors and daily habits.

 

Giriş: Bu çalışmanın amacı bir hastanede çalışan asistanların uyku kalitesini ve gün içi uykululuk durumunu değerlendirmek, cerrahi ve medikal branşlar arasında uyku kalitesini karşılaştırmak ve haftalık çalışma saatleri, nöbet sayıları , bazı günlük alışkanlıklar ve yaşam tarzının uyku kalitesi üzerine etkisini araştırmaktır. Yöntem: Çalışma üç bölümden oluşan veriler ile yapılmıştır; (i) demografik özellikler, günlük yaşam tarzı ve alışkanlıklarla ilgili bilgiler, (ii) Epworth uykululuk ölçeği (ESS) skoru, (iii) Pittsburgh uyku kalitesi ölçeği (PSQI) .Veriler katılımcılardan anket yoluyla ve etik kurallara uygun olarak alınmıştır. Bulgular: 138 asistan doktorun % 45.7’sinin uyku kalitesi PSQI   kesme puanı olan 5’e göre uyku kalitesi iyi olarak değerlendirildi. Ortalama ESS ve PSIQ puanları sırasıyla 6.59 ±3.92 ve 6.30 ±3.22 olarak bulundu. Epworth skoru ile gece nöbet sayısı (p=0.010), haftalık çalışma saatleri (p=0.006), günlük içilen sigara sayısı (p=0.033), günlük çay tüketimi (p=0.013) arasında anlamlı pozitif korelasyon bulundu. PSQI skorları ile, gece nöbeti sayıları (p<0.001), haftalık çalışma saatleri (p=0.007), günde içilen sigara sayısı (p=0.013), günlük kahve tüketimi (p=0.002) arasında anlamlı pozitif korelasyon saptandı. Cerrahi bölüm asistanlarının uyku kalitesi daha düşük rapor edildi (p=0.015). ESS skorları kadın asistanlarda ve cerrahi bölüm asistanlarında daha yüksek gözlendi ve bu farklar istatistiksel olarak anlamlı bulundu (sırasıyla p=0.018, p=0.008). Sonuç: Asistan doktorların uyku kalitesi ve gün içi uykululuk durumu, demografik faktörler ve günlük alışkanlıklarla ilgili olduğu kadar, haftalık çalışma saatlerinin uzunluğu, nöbet sayıları ve asistanlık yapılan bölüm gibi yaşam tarzı faktörleriyle de yakından ilişkilidir.
