Predictive factors of sleep quality and burnout in nurses working in transplant units during the COVID-19 lockdown - A cross-sectional study.

: There is minimal information regarding sleep disturbance and burnout during COVID-19 in nurses working within haematology-oncology and hematopoietic stem cell transplantation (HSCT) settings.: To identify socio-demographic and professional factors that predicted burnout and sleep disturbance during COVID-19 in nurses working in HSCT settings.: Data were collected using the Maslach Burnout Inventory and the Pittsburgh Sleep Quality Index. Descriptive statistics and linear regression examined relationships.: 308 responses were received. Nurses working in outpatient settings had greater emotional exhaustion (Rpartial = -0.12,  = 308,  = 0.03). Negative predictors for quality of sleep were transplant programme setting (Rpartial = -0.19,  = 308,  < 0.01) and years working in HSCT (Rpartial = -0.17,  = 308,  < 0.01). Other relationships were found on univariate analysis.: Institutions must offer programmes for nurses to develop sleep strategies, self-care, and work-related stress management.
