Relationship between quality of care, staffing levels, skill mix and nurse autonomy: literature review

Quality of care is a complex, multi-dimensional concept which presents researchers with a challenge when attempting to evaluate it. Traditional nursing assessment tools have fallen out of use, partly because they have failed to provide opportunities to engage with and access the views of patients or nurses. There is also evidence that patient satisfaction as an indicator of quality is compromised on a number of fronts. There is conflicting information on how nurses and patients think about quality. Research looking at the relationship between the selected organizational variables and perceptions of quality also suffers from a number of limitations. We argue that there is a requirement for more patient-centred research exploring perceptions of quality and differences in nurse staffing, skill mix and autonomy.
