Risk factors and a nomogram for predicting cognitive frailty in Chinese patients with lung cancer receiving drug therapy: A single-center cross-sectional study.

BACKGROUND: To identify independent factors of cognitive frailty (CF) and construct a nomogram to predict cognitive frailty risk in patients with lung cancer receiving drug therapy. METHODS: In this cross-sectional study, patients with lung cancer undergoing drug therapy from October 2022 to July 2023 were enrolled. The data collected includes general demographic characteristics, clinical data characteristics and assessment of tools for cognitive frailty and other factors. Logistic regression was harnessed to determine the influencing factors, R software was used to establish a nomogram model to predict the risk of cognitive frailty. The enhanced bootstrap method was employed for internal verification of the model. The performance of the nomogram was evaluated by using calibration curves, the area under the receiver operating characteristic curve, and decision curve analysis. RESULTS: A total of 372 patients were recruited, with a cognitive frailty prevalence of 56.2%. Age, education background, diabetes mellitus, insomnia, sarcopenia, and nutrition status were identified as independent factors. Then, a nomogram model was constructed and patients were classified into high- and low-risk groups with a cutoff value of 0.552. The internal validation results revealed good concordance, calibration and discrimination. The decision curve analysis presented prominent clinical utility. CONCLUSIONS: The prevalence of cognitive frailty was higher in lung cancer patients receiving drug therapy. The nomogram could identify the risk of cognitive frailty intuitively and simply in patients with lung cancer, so as to provide references for early screening and intervention for cognitive frailty at the early phases of drug treatment.

Exploring readiness for discharge, quality of discharge teaching, and fear of disease progression in lung cancer patients undergoing chemotherapy: A correlation analysis.

BACKGROUND: To explore the correlation between the current status of discharge preparation, quality of discharge teaching, and fear of disease progression among patients with lung cancer undergoing chemotherapy to provide a basis for improving patients' level of preparation. METHODS: In this cross-sectional study, convenience sampling was used to select 452 patients with lung cancer who received chemotherapy and were admitted to the Department of Medical Oncology of the Cancer Hospital, between February 2023 and April 2023. A general information questionnaire, discharge preparation scale, quality of discharge teaching scale, and fear of disease progression scale were used to conduct surveys 2 h before the patients were discharged. RESULTS: The score for discharge preparation among lung cancer patients with chemotherapy was 99.11 ± 14.79 and the item score was 8.26 ± 1.23. The score for quality of discharge teaching was 193.23 ± 37.69, and that for fear of disease progression was 25.47 ± 8.92. Multiple linear regression analysis showed that sex, marital status, treatment period, quality of discharge teaching, and fear of disease progression influenced discharge readiness among patients with lung cancer receiving chemotherapy. Pearson's correlation analysis showed that the total quality of the discharge guidance score was positively correlated with the discharge readiness score (r = 0.288, p < 0.001). In contrast, the total fear of disease progression score was negatively correlated with the discharge preparation score (r = -0.252, p < 0.001). CONCLUSION: Discharge readiness among patients with lung cancer receiving chemotherapy was relatively at the good level, and there was a significant correlation between readiness for discharge, discharge teaching and fear of disease progression in these patients. Therefore, it is necessary to provide effective discharge guidance and implement targeted intervention measures to further improve patient preparation, reduce the fear of disease progression, and promote patient ability of coping with the disease and overall satisfaction.
