Staffing practices in long-term care lack a clear evidence base and often seem to be guided by opinions instead of evidence. While stakeholders believe intuitively that there is a positive relationship between staffing levels and quality in nursing homes, the research literature is contradictory (1). In this editorial we consider the evidence found in a literature study that we conducted for the Dutch Ministry of Health, Welfare and Sports (VWS). The aim of this study was to summarize all available evidence on the relationship between staffing and quality in nursing homes. Specifically, we focused on the quantity and the educational background of staff and quality in nursing homes. The literature study has contributed to the recent Dutch quality framework for nursing homes (Kwaliteitskader verpleeghuiszorg in Dutch) of the National Health Care Institute. This quality framework was published in January 2017 and provides norms – among other quality aspects – for nursing home staffing. As well as a description of the main findings of the literature study, we present implications for different stakeholders charged with staffing issues in nursing homes.
