The objective of this study was to determine whether nurse staffing levels and modifiable characteristics of the nursing practice environment are associated with important quality indicators represented by the percentage of residents with pressure ulcers and numbers of deficiency citations in nursing homes. A cross-sectional design linked nurse survey data, aggregated to the facility level, with Nursing Home Compare, a publicly available federal database containing nursing home-level measures of quality. The facility sample consisted of 63 Medicare- and Medicaid-certified nursing homes in New Jersey, and the nurse survey sample comprised 340 registered nurses providing direct resident care. Characteristics of the practice environment were measured using the Practice Environment Scale of the Nursing Work Index, included in the nurse survey. The total number of deficiency citations, the percentage of residents with pressure ulcers, nurse staffing levels, and facility characteristics were extracted from the Nursing Home Compare database. Results indicated that a supportive practice environment was inversely associated with the percentage of residents with pressure ulcers and fully mediated the effect of profit status on this important outcome. The nursing practice environment and facility size explained 25% of the variance in quality deficiencies. There were no associations between staffing levels and quality indicators. Findings indicate that administrative initiatives to create environments that support nursing practice may hold promise for improving quality indicators in nursing homes.
