Effectiveness of advance directives for the care of terminally ill patients in Chiang Mai University Hospital, Thailand

Abstract

The key hypothesis behind advance directives (ADs) proposes that, if an intervention enhances a person's right to choose, a dying person will not opt for expensive, life-prolonging medical care and an ethically acceptable saving of resources will result. In order to assess the acceptability and effectiveness of ADs in reducing cardiopulmonary resuscitation (CPR) attempts and in-hospital death among terminally ill patients in a tertiary care hospital in northern Thailand, a non-randomized, controlled intervention study using an after-only unequivalent control group design was conducted. The majority of the subjects and the surrogates preferred to employ ADs in expressing their preferences on CPR and there was a high level of agreement between the subjects and surrogates on the decision. The use of ADs appeared to be effective in reducing futile CPR attempts and the in-hospital mortality rate among subjects during the index hospitalization. Advance directives were accepted well in this study setting. © 2008 The Authors Journal Compilation © 2008 Blackwell Publishing Asia Pty Ltd.
