노인 입원 환자의 섬망 예방을 위한 비약물 중재에 대한 체계적 문헌고찰

Abstract

Purpose The study was aimed to examine components and provider's characteristics of non-pharmacological intervention that affect delirium prevention in elderly inpatients. Additional effects on delirium prevention based on identified characteristics were explored. Methods Studies were searched by using seven electronic databases and examined through Preferred Reporting Items Systematic Review and Meta-Analysis (PRISMA) flow diagram. The Risk of Bias (ROB) and the Risk of Bias Assessment tool for Non-randomized Study (RoBANS) were used to evaluate the quality of each included study. Results Seven studies were selected for the systematic review. Most of the selected studies had a low risk of bias. Interventions of each study and delirium outcome were heterogeneous. Each multi-component non-pharmacological intervention consisted on average of five interventions. Giving orientation and promoting early mobilization were included in every study. Interventions that included giving orientation, promoting early mobilization, and supporting nutrition significantly decreased delirium incidence. Moreover, when health care providers who have an intimate relationship with patients provided non-pharmacological interventions, delirium incidence has significantly decreased. Conclusion Non-pharmacological intervention, such as giving orientation, promoting early mobilization, should be included to prevent delirium for elderly inpatients. It is important to include healthcare providers who have an intimate relationship or regular contact with patients in order to decrease delirium incidence.
