Path model on decision-making ability of clinical nurses.

AIMS AND OBJECTIVES: To identify and examine the relationship between the factors influencing the decision-making ability of clinical nurses in hospitals, South Korea, and to establish a model, to verify the fit and the effect. BACKGROUND: Clinical nurses are exposed to environments and situations where they make continuous decisions according to the need of direct treatment and nursing. DESIGN: This study used a cross-sectional descriptive design, relation prediction modelling and adheres to the STROBE guidelines. METHODS: The model construction was based on the information processing theory by Hansen and Thomas (Nursing Research, 17, 436, 1968). The model consists of 5 exogenous variables (expertise, critical thinking disposition, knowledge-sharing behaviour, nursing work environment, and decision-making stress) and 3 endogenous variables (analytic-systematic decision-making type, intuitive-interpretive decision-making type and decision-making ability). Participants were 274 clinical nurses, who were working at two hospitals in Seoul, South Korea. The data was analysed using SPSS WIN 18.0 and AMOS 20.0 program. Path analysis to verify the hypothetical model was used, and the fit was evaluated by χ2 /df, GFI, AGFI, NFI, CFI and RMSEA. Data were collected from March to May 2017. RESULTS: The fit index of the modified path model was χ2 /df = 2.25, GFI = .972, AGFI = .929, NFI = .967, CFI = .981 and RMSEA = .068. The analytic-systematic decision-making type had the greatest direct effect on the clinical nurses' decision-making ability, which is the final outcome variable, followed by significant direct and indirect effects on critical thinking disposition. CONCLUSION: This study suggests that the clinical nurses' decision-making ability in hospitals were leadingly influenced by analytic-systematic decision-making type and critical thinking disposition. RELEVANCE TO CLINICAL PRACTICE: In the nursing practice, nurses need to pay attention the analytic-systematic decision-making type and critical thinking disposition for improving decision-making ability of clinical nurses in hospitals.

Routine Follow-Up Radiographs for Ankle Fractures Seldom Add Value to Clinical Decision-Making: A Retrospective, Observational Study.

Currently, the routine use of radiographs for uncomplicated ankle fractures represents good clinical practice. However, radiographs are associated with waiting time, radiation exposure, and costs. Studies have suggested that radiographs seldom alter the treatment strategy if no clinical indication for the imaging study was present. The objective of the present study was to evaluate the effect of routine radiographs on the treatment strategy during the follow-up period of ankle fractures. All patients aged ≥18 years, who had visited 1 of the participating clinics with an eligible ankle fracture in 2012 and with complete follow-up data were included. The data were retrospectively analyzed. The sociodemographic and clinical characteristics and the number of, and indications for, the radiographs taken were collected from the medical records of the participating clinics. We assessed the changes in treatment strategy according to the radiographic findings. In 528 patients with an ankle fracture, 1174 radiographs were performed during the follow-up period. Of these radiographs, 936 (79.7%) were considered routine. Of the routine radiographs taken during the follow-up period, only 11 (1.2 %) resulted in changes to the treatment strategy. Although it is common practice to take radiographs routinely during the follow-up period for ankle fractures, the results from the present study suggest that routine radiographs seldom alter the treatment strategy. This limited clinical relevance should be weighed against the health care costs and radiation exposure associated with the use of routine radiographs. For a definitive recommendation, however, the results of our study should be confirmed by a prospective trial, which we are currently conducting.
