Preventive effect of pressure scores in liver transplant patients: a Meta-analysis

Objective To provide theoretical reference and practical guidance for clinical nursing through Meta-analysis method which is applied to explore the conventional nursing method and improvement intervention nursing methods to prevent liver transplantation the effect of pressure sores. Methods Databases including the Cochrane Library, PubMed, EMbase, OVID, China National Knowledge Infrastructure (CNKI), Wanfang Data and CBM, were searched by computer to collect the randomized controlled trails and quasi randomized controlled trials about the conventional nursing method and improvement intervention nursing methods for pressure sores of liver transplantation. Chinese Journal of Nursing, Chinese Journal of Modern Nursing, Journal of Nurses Training were searched by hand.The retrieval time was from February First, 1966 to February First, 2016. The studies were screened according to inclusion and exclusion criteria. The data were extracted and the quality was evaluated by two reviewers independently. Meta-analysis was conducted by RevMan 5.2 software. Results A total of 12 controlled trails involving 1 245 patients were included in this research, and there were 623 patients in the intervention group, and 622 patients in the control group. The results of meta-analysis showed that: the rate of pressure scores in intervention group was lower than the control group[OR=0.25, 95% CI(0.16, 0.38), P<0.01], [RR=0.29, 95% CI(0.20, 0.42), P<0.01]. The overall severity of pressure scores in the intervention group was significantly lower than that in the control group[OR=0.34, 95% CI(0.16, 0.73), P<0.01], [RR=0.57, 95% CI(0.37, 0.87), P<0.01]. Conclusions In the intervening group the rate of pressure ulcer and the overall severity of pressure scores was significantly lower than that in the control group, which shows that the intervention nursing method can effectively reduce the occurrence and stage of pressure scores in liver transplant patients and reduce the severity of pressure scores.
