The nursing work environment and quality of care: A cross-sectional study using the Essentials of Magnetism II Scale in England.

AIMS AND OBJECTIVES: To explore the structure of the Essentials of Magnetism II (EOMII) scale using data from nurses working in England; and to describe the impact of different aspects of the nursing work environment on nurse-assessed care quality (NACQ).

BACKGROUND: The EOMII Scale was developed in the United States to measure nursing work environments. It has been widely used in the United States and in a number of other countries, but has not yet been used in the UK.

DESIGN: Cross-sectional study.

METHODS: Registered nurses (n = 247) providing direct patient care in two National Health Service hospitals in England completed the EOMII scale and a single-item measuring NACQ. Principal components analysis was used to assess the structure of the scale. Correlation and regression analyses were used to describe the relationships between factors and NACQ.

RESULTS: A solution with explanatory variance of 45.25% was identified. Forty items loaded on five factors, with satisfactory consistency: (i) ward manager support; (ii) working as a team; (iii) concern for patients; (iv) organisational autonomy; and (v) constraints on nursing practice. While in univariate analyses, each of the factors was significantly associated with NACQ, in multivariate analyses, the relationship between organisational autonomy and NACQ no longer reached significance. However, a multiple mediation model indicated that the effect of organisational autonomy on NACQ was mediated by nurse manager support, working as a team and concern for patients but not constraints on nursing practice.

CONCLUSIONS: Subscales of the EOMII identified in an English sample of nurses measured important aspects of the nursing work environment, each of which is related to NACQ.

RELEVANCE TO CLINICAL PRACTICE: The EOMII could be a very useful tool for measuring aspects of the nursing work environment in the English Trusts particularly in relation to the quality of care.
