Use of advanced care directives by ambulatory chemotherapy patients with malignant disease: Likely predictors and impact of physician intervention.

e20544 Background: Despite their poor prognosis, few cancer patients have advanced care directives (ACD). Most often, ACD is discussed in an inpatient setting, when the patient is acutely ill and often nearing the end of life. Timely and thoughtful discussion would be better accomplished for both the patient and the family before such hospitalization.


METHODS
Interviews were done in 108 outpatients in an ambulatory chemotherapy center. A questionnaire noted whether ACD was executed or not, demographics (including education, religion and insurance status), performance status, characteristics of their cancer, and family status. All patients without ACD were counseled on the importance of ACD. The presence of an ACD was documented at each visit. Statistical comparison of patients with and without ACD at each visit was done.


RESULTS
The following variables were significantly associated with having an ACD at the first visit. Patients living alone could not be included in the logistic regression model, as none had advanced directives. However ACD execution differed significantly in patients living alone, compared with those living with family (0/33 vs 15/75; p=0.005). An additional 42 patients executed an ACD by the third visit. At the third visit, only living with family vs living alone remained significantly associated with having ACD. [OR=3.17 95% CI: 1.34, 7.50; p=0.009].


CONCLUSIONS
The following findings are noteworthy. Only 15/108 (14%) cancer outpatients had ACD. This disturbingly low rate increased to 55/108 (51%) after physician- initiated discussion. The following characteristics predicted not having ACD before intervention: younger age, absence of metastasis, better performance status, lower education status and living alone. After several physician interventions, only living alone remained a significant barrier to ACD execution by cancer outpatients. These results provide new insights and strategies to encourage improved advanced directive execution. [Table: see text] No significant financial relationships to disclose.
