Abstract: Objective: To understand the prognostic nutritional index (PNI) and postoperative rehabilitation status of elderly patients with lung cancer, and to explore the correlation between them, in order to provide reference for accelerating postoperative rehabilitation. Methods: Convenience sampling method was used to select 130 elderly lung cancer patients who met the inclusion and exclusion criteria in the general thoracic surgery department of a Class A tertiary hospital in Ningxia from June 2021 to February 2022. PNI, postoperative recovery and other indicators were collected. The general data and clinic pathological characteristics of patients in the high PNI group and the low PNI group were compared to analyze the status of PNI and postoperative rehabilitation and explore their correlation. Results: PNI score of elderly lung cancer patients was 48.61±4.90. There were differences in age, educational background and occupational status of elderly lung cancer patients in different PNI groups (P<0.05). In elderly lung cancer patients, PNI was positively correlated with ADL on the first day after surgery, and negatively correlated with postoperative daily drainage volume (P<0.05). Conclusion: The PNI of elderly lung cancer patients was at the level of malnutrition. The elderly patients with advanced age, low education level, and unemployed or retired were more prone to preoperative malnutrition. PNI can predict postoperative self-care ability and daily drainage fluid volume of elderly lung cancer patients to a certain extent. It is suggested that clinical medical staff can use PNI as a reference index for predicting postoperative rehabilitation of elderly patients with lung cancer, so as to accelerate their postoperative rehabilitation.
