Effects of psychological nursing care on anxiety and depression in perioperative patients with lung cancer: A systematic review and meta-analysis

Background: This study aimed to investigate the effects of psychological nursing care (PNC) on anxiety relief in perioperative lung cancer (LC) patients. Methods: We searched the Cochrane Library, PubMed, Embase, CNKI, CBM, and Wangfang electronic databases from inception to May 1, 2022. Eligible randomized controlled trials (RCTs) investigating the effects and safety of PNC on anxiety relief in perioperative LC patients. Anxiety was the primary outcome measure. The secondary outcomes were depression, length of hospital stay, and the occurrence of adverse events. Results: Six eligible RCTs with 494 patients were included in this study. Compared with routine nursing care, PNC showed better outcomes in terms of anxiety relief (mean difference [MD] = -13.24; random 95% confidence interval (CI), -18.28 to -8.20; P<.001), depression decrease (MD = -11.84; random 95% CI, -18.67 to -5.01; P < .001), and length of hospital stay (MD = -2.6; fixed 95% CI, -3.13 to -2.07; P < .001). No data on adverse events were pooled because only 1 trial reported this outcome. Conclusions: This study showed that PNC may benefit more than routine nursing care for patients with LC in anxiety, depression, and length of hospital stay. High-quality RCTs are needed to validate the current findings in the future.
