Thirteen Nonpharmacological Interventions for Increasing the Quality of Life in Patients with Advanced Cancer

Abstract

Background: A variety of nonpharmacological interventions that improve the quality of life of patients with advanced cancer have been difficult for medical staff to select through randomized controlled trials or traditional meta-analyses. Thus, a network meta-analysis is necessary. Objective: This study used network meta-analysis to analyze the effect of 13 different nonpharmacological interventions on improving the living quality of patients with advanced cancer. Methods: Five English databases were searched up to January 2019. The search strategy only included terms relating to or describing the intervention. Results: The study included 13 different nonpharmacological interventions. The overall efficacy was summarized through a holistic study of quality of life. The study found that the combined effect sizes of 13 nonpharmacological interventions crossed the invalid line (weighted mean difference, −13 [95% confidence interval, −33 to 8.5] to 1.7 [95% confidence interval, −18 to 22]), indicating that none of the intervention was significantly different from each other. By evaluating the heterogeneity of this outcome, no significant evidence of heterogeneity ( P > .05) was observed. Probability ranking according to the surface under the cumulative ranking curve showed that there was a great possibility for the CanWalk intervention and structured multidisciplinary intervention to improve outcomes for cancer patients. Conclusions: Thirteen nonpharmacological interventions did not significantly impact quality of life. Regarding the probability rank, CanWalk
