Risk of medication errors and nurses' quality of sleep: a national cross-sectional web survey study.

Objective: We aimed to evaluate quality of sleep and self-perception risk of medication errors, in a significantly-sized sample of nurses in Italy, using a web survey.

Subjects And Methods: An anonymous questionnaire about self-perception of quality of sleep (Pittsburgh Sleep Quality Index - PSQI) and risk of medication errors (based on the 7 R-rule), was made up and delivered by social media, i.e., Facebook and Instagram. Risk of medication errors was intended as near misses, i.e., accidents that do not cause the patient harm.

Results: A poor quality of sleep stated by PSQI score >5, was present in 87.9% of subjects and the risk of medication errors during the last shift was reported in 76% of them. However, more than half of nurses' sample (60.1%) reported a good or excellent self-perception quality of sleep. Risk of medication errors was associated with poor quality of sleep and it was independently associated with short resting time after night shift and bad self-perception quality of sleep (OR 3.165, 95% CI 1.468-6.827, p=0.003).

Conclusions: Absence of proper resting is crucial on performance even if nurses perceived a good quality sleep. The relationship between shift work, poor sleep quality, and risk of medication errors represents crucial point for all health professionals' community, and web-survey represents a valuable information in order to capture the risk of medication errors. Health care organizations should encourage such a type of research in order to show a more proactive approach towards patient safety.
