Abstract:Objective To investigate the effects of FOCUS-PDCA model combined with nursing version Mini CEX in improving the post competency of thoracic surgical nurses. Methods A convenience sampling method was used to select 32 nurses working in the Department of Thoracic Surgery in Zhongnan Hospital of Wuhan University from February 2021 to February 2023. Based on the competent post level requirements at each level of thoracic surgery (N1-N4), 5 work scenarios were selected from easy to difficult, and the nursing version Mini-CEX was used to evaluate nurses' clinical comprehensive abilities at each level in the required versus optional scenarios. Combined with FOCUS-PDCA model to analyze the main factors affecting the competency of various hierarchical posts, the conditions, theories and skill ranges and the continuous improvement scheme of each level of advancement were revised according to the principle of step-by-step. Results Compared with those befter using PDCA model management, the total self-assessment scores of 32 nurses' post competence and the nursing version of Mini-CEX assessment scores after using PDCA mode management were significantly higher (81.22±4.40 vs 72.44±6.14, t=19.165, P<0.01; 77.78±8.72 vs 53.75±7.22, t=38.182, P<0.01). After training, the nurses' evaluation of the effect of on-the-job training model higher than that before training (P<0.05).Conclusion The use of FOCUS-PDCA combined with nursing version Mini CEX management can improves the competency of nurse posts of thoracic surgery effectively, and provide guarantees for safety management of patients.
