Abstract

Objective: This study aimed to evaluate sleep quality and related factors among patients in the coronary care unit (CCU), inpatient cardiology ward, and outpatient cardiology clinic using the Pittsburgh Sleep Quality Index (PSQI). Materials and Methods: This cross-sectional observational study was conducted at a secondary care hospital between March 2019 and March 2020. A total of 153 adult patients from three cardiology settings were included. Sleep quality was assessed using PSQI. Global and component scores were compared across groups using the Kruskal–Wallis test, followed by Bonferroni-adjusted post-hoc pairwise comparisons where appropriate. Results: The mean global PSQI score was highest in the CCU group (7.5 ± 3.1), followed by the inpatient group (5.6 ± 3.1) and the outpatient group (4.4 ± 1.9). Global PSQI scores differed significantly among the groups (Kruskal–Wallis H = 27.743, p < 0.001). Bonferroni-adjusted post-hoc analysis showed significantly higher PSQI scores in the CCU group compared with both the inpatient group (p = 0.003) and the outpatient group (p < 0.001). No significant difference was observed between the inpatient and outpatient groups (p = 0.166). Poor sleep quality (PSQI > 5) was most prevalent in the CCU group (77.6%), whereas good sleep quality was most frequent in the outpatient group (75.5%). Conclusion: Sleep quality differed significantly across cardiology care settings, with the greatest impairment observed in the CCU group. Patients in this group showed worse outcomes in multiple sleep domains, particularly sleep latency, sleep disturbances, use of sleep medication, and daytime dysfunction.

Özet

Amaç: Bu çalışma, Pittsburgh Uyku Kalitesi İndeksi (PSQI) kullanılarak koroner yoğun bakım ünitesi (KYBÜ), kardiyoloji servisi ve kardiyoloji polikliniğinde takip edilen hastalarda uyku kalitesini ve ilişkili faktörleri değerlendirmeyi amaçlamıştır. Gereç ve Yöntemler: Bu kesitsel gözlemsel çalışma, Mart 2019 ile Mart 2020 tarihleri arasında ikinci basamak bir hastanede gerçekleştirilmiştir. Üç farklı kardiyolojik bakı biriminde toplam 153 erişkin hasta çalışmaya dahil edilmiştir. Uyku kalitesi PSQI kullanılarak değerlendirilmiştir. Global ve alt bileşen skorları gruplar arasında Kruskal–Wallis testi ile karşılaştırılmış ve uygun durumlarda Bonferroni düzeltmeli post-hoc ikili karşılaştırmalar yapılmıştır. Bulgular: Ortalama global PSQI skoru KYBÜ grubunda en yüksek (7.5 ± 3.1) olup, bunu kardiyoloji servisi (5.6 ± 3.1) ve poliklinik grubu (4.4 ± 1.9) izlemiştir. Global PSQI skorları gruplar arasında anlamlı farklılık göstermiştir (Kruskal–Wallis H = 27.743, p < 0.001). Bonferroni düzeltmeli post-hoc analiz, KYBÜ grubunun hem servis grubuna (p = 0.003) hem de poliklinik grubuna (p < 0.001) göre anlamlı derecede daha yüksek PSQI skorlarına sahip olduğunu göstermiştir. Servis ve poliklinik grupları arasında ise anlamlı fark bulunmamıştır (p = 0.166). Kötü uyku kalitesi (PSQI > 5) en sık KYBÜ grubunda (%77.6) görülürken, iyi uyku kalitesi en sık poliklinik grubunda (%75.5) saptanmıştır. Sonuç: Uyku kalitesi, kardiyolojik bakı birimleri arasında anlamlı farklılık göstermiş olup, en belirgin bozulma KYBÜ grubunda gözlenmiştir. Bu gruptaki hastalar, özellikle uyku latensi, uyku bozuklukları, uyku ilacı kullanımı ve gündüz işlev bozukluğu olmak üzere birden fazla uyku alanında daha kötü sonuçlar göstermiştir.
