Advance directive (AD) is an important part in palliative care because it can increase patient’s quality of life and helps with a dignified death but currently it is still not well-known or widespread within the general population. Objective: To find if education about AD increases the completion of living will in chronically ill patients. Methods: A literature search was performed on 13 August 2021 with 263 articles found. After manual title screening and duplicate removal, 5 articles were selected and critically appraised with 2010 CEBM Oxford criteria. Result: In Chung et al, education about AD increases the completion of living will from 10.26% to 35.94%. In Courtright et al 70-80% patients were interested in making AD after education about AD with completion rates of 13.1% and 12.2% for each group. In Halpern et al completion rates were 50.66%, 55.15%, and 55.35% for each group; and meta-analysis in Houben et al results in a favorable odds ratio (OR= 3,26; 95% CI= 2,00-5,32; P < 0,00001). Conclusion: Education about AD increases patient’s willingness to create and eventually complete AD/living will and the concordance of written AD with medical procedures that the patient receives.
