Introduction: Sleep and rest have an important role on re-storage, maintenance and
increase of patient turnover and health. Physical illness accompanied with pain and other
inconvenience could disturb sleep. So, the aim of this study was to evaluate sleep quality and
its associated factors in hospitalized patients in Babol teaching hospitals.
Methods: This Cross-Sectional study was carried out on 200 over 18 years old patients
who were inpatient in various wards of Babol hospitals and were selected by cluster
sampling. Data was gathered by means of two questionnaires: The Pittsburgh Sleep Quality
Index (PSQI) and sleep affecting environmental factors questionnaire. Analysis of variance
with SPSS software was used for data analysis.
Results: Half of the participated patients were men and half of them were women. Mean
age of the patients was 49.3±16.68. 84% of the patients were married and 39% of them
were illiterate. Mean total sleep quality score of patients was 5.97±3.02. 36.4% of the
patients had desirable sleep quality and 63.6% of them showed undesirable sleep quality.
Mean sleep quality score of patients in different wards had significant difference (P<0.02),
as patients in the orthopedic ward had the worst sleep quality and patients in the lung ward
had the best sleep quality. The sleep quality had a significant correlation with duration of bed
rest (P<0.001).
Conclusion: Most of the patients in this study showed undesirable sleep quality. As sleep
affect performance and quality of life, implementing a necessary policy for removing or
controlling sleep disturbance could help the patients.
