Nurse-led inpatient care: opening the 'black box'.

With recent evaluations contradicting early reports of improved outcomes from nurse-led inpatient care, the 'black box' of nurse-led care must be opened in order to examine the model of treatment. We present findings on the processes of care in one nurse-led unit (NLU), compared with an acute ward. Patterns and quality of nursing care were quantified using bar-code technology to measure type, frequency and duration of nursing activities and Quality Patient Care Scale to measure the quality of care.
