“…This study investigated the prevalence of insomnia symptoms in clinically stable older psychiatric patients and their impact on QOL during the COVID-19 outbreak in China. Over half (57.1%, 95%CI: 53.9%-60.2%) of the patients suffered from insomnia symptoms, which is higher than the corresponding gures reported in other populations using the same measure and cutoff value during the COVID-19 outbreak, such as frontline clinicians (28.75%-38.4%) (36)(37)(38), inpatients with COVID-19 (42.8%) (14), breast cancer patients (36.2%) (39), and the general population (28.5%) (40). In addition, the prevalence of insomnia symptoms in this study was also much higher than the gures in both the general population (15.0%, 95%CI: 12.1%-18.5%) (41) and older psychiatric patients (27.0%, 95%CI: 24.5%-29.4%) (42) in China before the COVID-19 outbreak, although measures on insomnia symptoms were different.…”

The most common criteria for assessing sleep disturbances were PSQI 16−21 88,92,102 and ISI ≄8, 97,98,107 which are used by three studies each, yielding a pooled prevalence of 19% (95% CI: 0-68%, I 2 = 99%) and 43% (95% CI: 31-56%, I 2 = 73%), respectively. The remaining studies used unvalidated custom questionnaires or interviews for assessing sleep disturbances.…”
