Five subscales were derived from the Nursing Work Index (NWI) to measure the hospital nursing practice environment, using 1985-1986 nurse data from 16 magnet hospitals. The NWI comprises organizational characteristics of the original magnet hospitals. The psychometric properties of the subscales and a composite measure were established. All measures were highly reliable at the nurse and hospital levels. Construct validity was supported by higher scores of nurses in magnet versus nonmagnet hospitals. Confirmatory analyses of contemporary data from 11,636 Pennsylvania nurses supported the subscales. The soundness of the new measures is supported by their theoretical and empirical foundations, conceptual integrity, psychometric strength, and generalizability. The measures could be used to study how the practice environment influences nurse and patient outcomes.

Objective-The objective of this study was to analyze the net effects of nurse practice environments on nurse and patient outcomes after accounting for nurse staffing and education.Background-Staffing and education have well-documented associations with patient outcomes, but evidence on the effect of care environments on outcomes has been more limited.

Background:The nurse work environment is theorized to influence the quality of nursing care, nurse job outcomes, and patient outcomes. Objective:The aim of this meta-analysis was to evaluate quantitatively the association of the work environment with job and health outcomes.Research Design: Relevant studies published through September 2018 were identified. Inclusion criteria were use of a nationally endorsed work environment measure and reporting of odds ratios (ORs) and 95% confidence intervals from regression models of 4 outcome classes: nurse job outcomes, safety and quality ratings, patient outcomes, and patient satisfaction. Pooled ORs and confidence intervals were estimated for each outcome using fixed or random effects models.Subjects: Of 308 articles reviewed, 40 met inclusion criteria. After excluding 23 due to sample overlap or too few observations to meta-analyze, a set of 17 articles, comprising 21 independent samples, was analyzed. Cumulatively, these articles reported data from 2677 hospitals, 141 nursing units, 165,024 nurses, and 1,368,420 patients, in 22 countries.Measures: Practice Environment Scale of the Nursing Work Index, a National Quality Forum nursing care performance standard.Results: Consistent, significant associations between the work environment and all outcome classes were identified. Better work environments were associated with lower odds of negative nurse outcomes (average OR of 0.71), poor safety or quality ratings (average OR of 0.65

Care environment elements must be optimized alongside nurse staffing and education to achieve high quality of care.
