Effect of decision aid tools for advance care planning in patients with cancer: a Meta-analysis / 中国实用护理杂志

ABSTRACT

Objective:To systematically evaluate the effect of decision aid tools for advance care planning (ACP) in patients with cancer.Methods:Randomized controlled trials about the effect of decision aid tools for ACP in patients with cancer were retrieved from Embase, PubMed, CINAHL, the Cochrane Library, PsycINFO, Chinese Biomedical Literature Database, VIP, China National Knowledge Internet and Wanfang Data. The retrieval time was from inception to February 23, 2022. Literature screening, quality evaluation and data consolidation were carried out independently by two researchers. Then, RevMan 5.3 software was used for Meta analysis.Results:A total of 13 researches were included, involving 2 151 cancer patients. Meta-analysis showed that the signing of advance directives ( OR=1.81, 95% CI 1.22-2.69, Z=2.95, P<0.01) and knowledge scores related to ACP( MD=0.58, 95% CI 0.35-0.81, Z=4.90, P<0.01) in experimental group was higher than that in control group, but receiving cardiopulmonary resuscitation treatment before death ( MD=0.33, 95% CI 0.21-0.53, Z=4.64, P<0.01) and the level of decision confliction ( MD=-3.69, 95% CI-6.43--0.95, Z=2.64, P<0.01) in experimental group was lower than those in control group, and the differences were statistically significant. Conclusions:Existing evidence shows that decision aid tools can improve cancer patients′ awareness of ACP, help patients to join in ACP discussions and sign advanced directives, reduce patients' preference for cardiopulmonary resuscitation treatment before death and reduce decision-making conflicts.
