Abstract：Objective To evaluate the effect of APACHE Ⅱscoring system in nursing care of elderly patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) combined with delirium. Methods A total of 62 elderly patients with acute exacerbation of COPD combined with delirium were randomly divided into the observation group and the control group, with 31 cases in each group. The control group was given routine nursing, and the observation group was given ICU grouped nursing intervention according to APACHE Ⅱscore of patients. The clinical curative effect, the mortality rate, time in ICU, duration of mechanical ventilation, length of stay and satisfaction rate of nursing care were compared between two groups. Results There was no significant difference in mortality rate between two groups (P＞0.05). The observation group had a lower incidence of complication(P＜0.01), shorter time in ICU, shorter duration of mechanical ventilation and shorter length of stay compared with the control group (P＜0.05 or P＜0.01). The nursing satisfaction rate was 9677% in the observation and was 7096% in the control group, with a significant difference (P＜0.01). Conclusion Nursing risk assessment based on the APACHE II score of elderly patients with acute exacerbation COPD combined delirium is highly recommend. It can reduce risk of complication and average length of stay, and to improve ICU nursing quality.
