Abstract：Objective To explore risk assessment and nursing strategies of the postoperative lung infection physiology and surgical severity scoring system (POSSUM). Methods The data of 80 middle-aged and elderly patients who underwent surgical treatment in the Third People′s Hospital of Jiujiang City, Jiangxi Province from January 2019 to March 2020 were retrospectively analyzed. 40 patients who underwent general surgery routine care from January to August 2019 were included in the control. In the observation group, 40 patients who used the POSSUM score-based lung infection grading preventive care strategy from September 2019 to March 2020 on the basis of routine care were included in the observation group. The nursing time of both groups was 1 month, acute physiology and chronic health score Ⅱ (APACHEⅡ), incidence of lung infection after nursing, and total nursing satisfaction were compared between the two groups. Results After 1 month of nursing, the APACHE Ⅱscore of the observation group was lower than that of the control group, the total incidence of lung infection was 2.50% (1/40), was lower than that of the control group of 20.00% (8/40), and total satisfaction was 97.50%, higher than that of the control group of 77.50%, the differences were statistically significant (P<0.05). Conclusion The use of POSSUM for surgical patients to assess postoperative risks and formulate targeted grading nursing plans based on the assessment results can significantly reduce the risk of postoperative lung infections, and significantly improve the prognosis and patient satisfaction, which has promotion value.
