Summary

A retrospective longitudinal cohort study in English hospitals that linked shift-level registered nurse and nursing assistant staffing to the risk of patient death. Lower registered nurse staffing was associated with higher mortality risk, while additional assistant staffing did not offset that shortfall, informing how wards are staffed.
