Sleep is essential for the physical and psychological restoration of inpatients, and lack of sleep results in sleep deprivation and poor sleep quality, with potentially harmful consequences. ⋯ The literature review showed that both ICU and acute ward settings affect patients' sleep and both use similar strategies to improve this. Nevertheless, noise and sleep disturbances remain the most critical sleep-inhibiting factors in both settings. The review recommended future research should focus on behavioural changes among health professionals to reduce noise and improve patients' sleep.
