Use of advance directives: a survey in three clinics

Advance directives (ADs) are instructions from patients to their physician and family regarding their wishes for medical care in the event they become incapable of communicating those wishes. This study sought to describe the characteristics of adults who have completed advance directives and those who have expressed interest in them, and to determine what distinguishes these groups from the group with no interest in ADs. A further objective was to survey the study population on the barriers to completion of ADs. A random sample of 160 outpatients visiting one of three clinics (General Internal Medicine Clinic (GIM), HIV Clinic, and Oncology Clinic) were selected for the study. A 10-item questionnaire was administered which included questions on familiarity with, sources of information on, and interest in ADs. Demographic information was collected as well as information on subject experiences with illness and death. Twenty-six of the 160 participants (16%) had completed ADs. The prevalence of completion differed among the three clinics: HIV Clinic 25%, Oncology Clinic 18%, and GIM Clinic 8%. Nearly all patients (95%) expressed interest in ADs. Those not interested in ADs were more likely than those who were interested or those who had already completed ADs to have been in an intensive care unit themselves. Multiple barriers to completing ADs were identified. Advance directives are still used by relatively few people despite a general openness and interest in them. Few characteristics, demographic and otherwise, were identified to distinguish those who completed ADs from those who did not.
