Abstract There is plenty of research showing that low nurse staffing levels in hospital wards are associated with worse outcomes for patients and staff, but little practical guidance for those who want to set ‘safe’ staffing levels. Much of the evidence comes from health systems that are different to the UK's. This article summarises evidence derived from studies conducted in the NHS. Although the evidence does not give us an optimal ‘safe’ staffing level, it reinforces that a ratio of one registered nurse to eight patients is a level at which risk is known to be increased.
