The impact of nursing grade on the quality and outcome of nursing care

The large industry which has grown up around the estimation of nursing requirements for a ward or for a hospital takes little account of variations in nursing skill; meanwhile nursing researchers tend to concentrate on the appropriate organisation of the nursing process to deliver best quality care. This paper, drawing on a Department of Health funded study, analyses the relation between skill mix of a group of nurses and the quality of care provided. Detailed data was collected on 15 wards at 7 sites on both the quality and outcome of care delivered by nurses of different grades, which allowed for analysis at several levels from a specific nurse-patient interaction to the shift sessions. The analysis shows a strong grade effect at the lowest level which is 'diluted' at each succeeding level of aggregation; there is also a strong ward effect at each of the lower levels of aggregation. The conclusion is simple; you pay for quality care.
