Nurse–patient ratios as a patient safety strategy: a systematic review.

Shekelle PG.

Higher nurse staffing levels appear to be associated with reduced inpatient mortality and adverse events, according to this AHRQ-funded systematic review published as part of a patient safety supplement in the Annals of Internal Medicine. However, implementation of this strategy is limited by the fact that no study yet has prospectively evaluated the effect of an intentional change in nurse–patient ratios.
