1043 Subjective Sleep Quality in Pulmonary Rehabilitation Patients: An Update

Abstract Introduction The impact of pulmonary rehabilitation on subjective sleep quality is not well established. The Pittsburgh Sleep Quality Index (PSQI) is a validated questionnaire that assesses levels of sleep disturbance over a one-month period. We describe updated subjective sleep quality outcomes measured through PSQI questionnaires in patients enrolled in a pulmonary rehabilitation program at Northwell Health. Methods All new pulmonary rehabilitation patients at Northwell Health Pulmonary Rehabilitation in New Hyde Park, NY were invited to participate. Subjects participated in the standard pulmonary rehabilitation program (3 times weekly for 8 weeks with a total of 24 sessions). The PSQI questionnaire was completed at sessions 1, 12, and 24. Demographic and clinical characteristics were summarized using counts and percentages for categorical variables, and either mean and standard deviation or median and interquartile range for numeric variables, as appropriate. Differences between baseline and post-intervention PSQI scores were computed to estimate change at different time points and reported as medians and interquartile ranges and were compared using Wilcoxon Signed Rank tests less than or equal to 0.05 level. Results 67 subjects were included in this analysis. 56% of subjects were female with mean age of 68 years (SD±10.97) and BMI 28.73 (SD ±6.97). 44% of subjects were male with mean age of 71 years (SD ±7.95) and BMI 29.79 (SD ±6.62). Comorbid conditions included COPD (53.73%), ILD (40.30%), pulmonary hypertension (14.93%), and obstructive sleep apnea (37.31%). Total PSQI scores and subscores were analyzed. The PSQI total score improved from a mean of 7.68 at session 1 to 6.79 at session 24 (p=.0282). The variable with the most significant change was the daytime dysfunction subscore, which improved from session 1 to 12 (p=.0116) and session 1 to 24 (p=0.0054). Conclusion Pulmonary rehabilitation is an effective intervention to improve sleep quality. Our analysis suggests that pulmonary rehabilitation improves overall quality of sleep and daytime dysfunction due to sleepiness in patients with advanced lung disease. Further investigation is needed to assess long-term impacts of this intervention. Support (if any)
