How do three components of professional commitment influence nurse-reported patient-centred care and care quality?

AIMS AND OBJECTIVES: To test how the three components of professional commitment (i.e. affective, continuance and normative professional commitment) are associated with nurse-reported patient-centred care and care quality. BACKGROUND: Patient-centred care and care quality are the two critical care outcomes. However, no study has yet examined how the three components of professional commitment are related to nurse-reported patient-centred care and care quality, showing a research gap. DESIGN: This study adopted a two-wave design (first wave in 2017 and second wave in 2019), which is known to reduce the possibility of reverse causality, and which was conducted in a large hospital in Northern Taiwan. METHODS: Proportionate random sampling was used. Full-time nurses were surveyed, while nursing students, interns, nurse practitioners and nursing supervisors were excluded. The first wave included 524 nurses, and 438 nurses were retained in the second wave. We used confirmatory factor analysis to verify the psychometric properties of the measures. Structural equation modelling was used to implement hypothesis testing. We used the Professional Commitment Scale of Meyer et al. (Journal of Applied Psychology, 1993, 78, 538), the Patient-Centered Care Scale of Laird-Fick et al. (Patient Education and Counseling, 2011, 84, 90) and the Care Quality Perceptions Scale of Teng et al. (Journal of Nursing Management, 2010, 18, 275). The STROBE statement was chosen as the EQUATOR checklist. RESULTS: Affective professional commitment was positively associated with nurse-reported patient-centred care (ß = .18, p = .002 and .01), which was positively associated with nurse-reported care quality (ß = .85, p < .001). Affective and normative professional commitment were also positively associated with nurse-reported care quality (ß = .17, p < .001). CONCLUSIONS: Our findings offer insights for nursing managers that nurses' affective and normative professional commitment could help upgrade care outcomes. Hospital managers should consider professional commitment as relevant to their workforce. RELEVANCE TO CLINICAL PRACTICE: Nursing managers could publicise reports documenting nurses' significant contributions to public health. This could strengthen affective professional commitment among nurses.

[Effects of feixianping on serum interleukin-6 and oxygen partial pressure in pulmonary fibrosis rats].

OBJECTIVE: To study the effects of feixianping (FXP) in improving hypoxemia and on serum interleukin-6 (IL-6) in experimental rats with pulmonary fibrosis (PF). METHODS: Two hundred and forty healthy male SD rats were randomly divided into 5 groups, 48 in each group, i.e. the normal control group (A), the model group (B), the prednisone group (C) and the two FXP groups of high (21.6 mg x kg(-1)) and low (10.8 mg x kg(-1)) dosage (D and E). PF model rats were established by intratracheal instillation of bleomycin, excepting those in Group A, to which normal saline was administered. The corresponding treatment to various groups started from the 1st day after modeling. Rats were sacrificed in batch at 4 time points, i.e., the 7th, 14th, 21st and 28th day, their arterial blood was collected for determination of blood partial pressure of oxygen (PaO2) and serum IL-6 content. RESULTS: Serum IL-6 content in Group B at all the time points was higher than that in other groups at the same time points (P<0.01). In the FXP treated groups (D and E), levels of IL-6 at the 7th, 14th and 28th day showed no significant difference from those in Group A and C. Since the 14th day, FXP showed its effect in improving hypoxemia in experimental rats which could basically keep in accordance with the effect of prednisone. CONCLUSION: FXP can ameliorate hypoxemia and reduce the level of serum IL-6 in experimental PF rats.
