Relationship between sleep quality and the psychological status of patients hospitalised with COVID-19

Aim: We explored the sleep quality of patients who required mental health and clinical interventions in our hospital after being diagnosed with COVID-19. Method: We enrolled 189 patients hospitalised with COVID-19 in April and May of 2020, of whom 78 were female and 111 male. We evaluated sleep quality and related factors in terms of demographic characteristics, the duration of hospitalisation, and Pittsburgh Sleep Quality Index (PSQI) and Hospital Anxiety-Depression Scale scores. Results: All participants were divided into two groups according to PSQI score: n = 102 (54%) patients with PSQI scores >= 5 and n = 87 (46%) patients with PSQI scores <5. No significant between-group difference was evident in terms of age, gender, marital status, educational level, or chronic disease history. The duration of hospitalisation (p = 0.002) and the depression rate (p = 0.010) were higher in the group exhibiting poor sleep quality (PSQI score >= 5). Conclusion: The duration of hospitalisation was longer in patients experiencing poor sleep quality. Therefore, improvement in sleep quality will reduce the length of hospital and intensive care unit stays. (C) 2021 Elsevier B.V. All rights reserved.
