Abstract
Understanding factors associated with post-discharge sleep quality among COVID-19 survivors is important for intervention development. This study investigated sleep quality and its correlates among COVID-19 patients 6 months after their most recent hospital discharge. Healthcare providers at hospitals located in five different Chinese cities contacted adult COVID-19 patients discharged between 1 February and 30 March 2020. A total of 199 eligible patients provided verbal informed consent and completed the interview. Using score on the single-item Sleep Quality Scale as the dependent variable, multiple linear regression models were fitted. Among all participants, 10.1% reported terrible or poor sleep quality, and 26.6% reported fair sleep quality, 26.1% reported worse sleep quality when comparing their current status with the time before COVID-19, and 33.7% were bothered by a sleeping disorder in the past 2 weeks. After adjusting for significant background characteristics, factors associated with sleep quality included witnessing the suffering (adjusted B = -1.15, 95% CI = -1.70, -0.33) or death (adjusted B = -1.55, 95% CI = -2.62, -0.49) of other COVID-19 patients during hospital stay, depressive symptoms (adjusted B = -0.26, 95% CI = -0.31, -0.20), anxiety symptoms (adjusted B = -0.25, 95% CI = -0.33, -0.17), post-traumatic stress disorders (adjusted B = -0.16, 95% CI = -0.22, -0.10) and social support (adjusted B = 0.07, 95% CI = 0.04, 0.10). COVID-19 survivors reported poor sleep quality. Interventions and support services to improve sleep quality should be provided to COVID-19 survivors during their hospital stay and after hospital discharge.

Summary
Understanding factors associated with post-discharge sleep quality among COVID-19 survivors is important for intervention development. Factors associated with sleep quality among COVID‐19 survivors characteristics to assess sleep quality compared with lengthier sleep questionnaires such as the Pittsburgh Sleep Quality Index (PSQI) and the Morning Questionnaire-insomnia.[22] This instrument has been demonstrated to be a reliable and valid measure that does not significantly increase the burden on respondents and has been used in a number of published studies,[23,24,25,26,27] including studies conducted in China.[24] In addition, participants were asked to compare their current sleep quality with that in the time before COVID-19 (response categories: 1 = got worse, 2 = no change, 3 = got better). One item extracted from the PHQ-9 scale was used to assess whether participants were bothered by sleep disorder: ‘Whether you have trouble falling or staying asleep, or sleeping too much in the past two weeks’ (response categories: not at all, several days, more than half the days and nearly every day).[6]
