探讨基于PDCA循环的过渡期护理对老年人瓣膜置换术后重症监护室（ICU）出科时期的干预效果。

选取2020年10月至2021年9月在遵义医科大学附属医院行瓣膜置换术的老年患者60例，其中30例在ICU出科过渡期采用常规护理（对照组），余30例采用基于PDCA循环的过渡期护理（观察组）。观察两组患者干预前后超声心动图相关指标左室射血分数（LVEF）和左心室舒张末期容积（LVEDV）、医院焦虑抑郁评分量表（HADS）评分、中文版Mishel疾病不确定感量表（MUIS）评分，以及日常生活能力评估量表（ADL）评分变化情况。计数资料的比较采用χ²检验，计量资料的比较采用t检验。

护理后，观察组LVEF和LVEDV指数均高于对照组（t=3.286、2.035，P<0.05），HADS-A、HADS-D和MUIS评分均低于对照组（t=3.873、3.873、6.076，P<0.01），ADL评分高于对照组（t=6.076，P<0.01）。

基于PDCA循环的过渡期护理可明显改善老年人瓣膜置换术后从ICU转入普通病房期间的焦虑情绪和疾病不确定感，促进心功能恢复，提高自理能力。

To explore the effect of PDCA cycle nursing elderly patiens received valve replacement transferred from ICU to general ward.

A total of 60 elderly patients undergoing valve replacement in Affiliated Hospital of Zunyi Medical University from October 2020 to September 2021 were selected. Among them, 30 cases received routine nursing during the transition period of ICU discharge (control group), and the remaining 30 cases received transitional nursing based on PDCA cycle (observation group). Left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), hospital anxiety and depression rating scale (HADS), Chinese version of Mishel disease uncertainty scale (MUIS), and activities of daily living (ADL) scores were compared between the two groups before and after intervention. Chi-square test was used for comparison of counting data groups, and t test was used for comparison of measurement data.

After nursing, LVEF and LVEDV in the observation group were higher than those in the control group (t=3.286, 2.035, P < 0.05), HADS-A, HADS-D and MUIS scores were lower than those in the control group (t=3.873, 3.873, 6.076, P < 0.01), and ADL score was higher than that of control group (t=6.076, P < 0.01).

Transitional nursing based on PDCA cycle can significantly improve patients' anxiety and disease uncertainty, promote the recovery of patients' heart function and self-care ability.
