Quality of sleep for hospitalized patients in Rasoul-Akram

  Background: Sleep disturbances have negative effects on medical conditions, mental health and cognitive performance. It was shown that about 60% of inpatients suffer from sleep problems. The aim of this study was to assess the correlation between sleep quality and other factors in the inpatients of Rasoul-e-Akram hospital.   Methods: In this cross-sectional study, all the hospitalized patients in twelve wards of Rasoul-e-Akram hospital during September 2012, were examined. Sleeping habits of 209 inpatients of different wards were assessed through the Persian version of Pittsburgh Sleep Questionnaire (PSQI). A self-designed 18- question questionnaire was conducted for all patients in order to assess their attitude to interior and atmosphere of wards. Content validityand test retest reliability were evaluated. The pain level was also measured by the visual analog scale (VAS) and scores analyzed by the statistical methods of frequency, percentage, chi-square and logistic regression.   Results: The mean of the total scores in PSQI was 8.8 ±4.8 and 70.8% of the patients were 'poor sleepers'(global PSQI>5). Age and gender had no effect on the PSQI total score, but the number of roommates, type of the ward, hospitalization period, presence and severity of pain, taking sleep medication and attitude toward the overall atmosphere and interior of wards have caused deviation in scores.   Conclusion: Sleep problems are quite frequent in medical inpatients. Pain management and modification of the ward interior and atmosphere can impact inpatients sleep quality.
