BACKGROUND/RATIONALE:
Improving care of the dying has become a recent national priority. Despite multiple efforts to improve the experience for dying patients, few well-established standardized outcome measures exist to assess the quality of life at the end of life, particularly ones that acknowledge explicitly the variability of patient and family perspectives. OBJECTIVE(S): Our primary objective is to develop and validate a clinical and research instrument to assess the quality of dying. This project consists of two primary components: 1) first, use previously collected data on the attributes of a good death to develop a multidimensional scale that assesses the quality of dying; and 2) validate the assessment tool in populations of seriously ill patients. METHODS: Questionnaire items were derived from focus group and national survey data that identified the importance of various attributes to the quality of dying. In phase I validation, an assessment of factor structure, we administered the instrument to equal numbers of VA and Duke University Medical Center outpatients with advanced cancer, congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD) and end-stage renal disease (ESRD). We assessed psychometric properties using factor analysis. In phase II validation, an assessment of reliability and convergent and divergent validity, we administered a reduced version of the questionnaire (31 items) and a battery of other scales to 200 seriously ill outpatients (100 VA, 100 Duke). To assess test-retest reliability, the study questionnaire is readministered, by phone, within one week. FINDINGS/RESULTS: In phase I, 200 patients completed the instrument (response rate = 85%); 74% were male, 64% were Caucasian and 34% African-American. Diagnoses included 64% cancer, 19.5% CHF, 10% ESRD and 6.5% COPD. After excluding items with >90% agreement, factor analysis yielded a final instrument with 25 items in five distinct domains (overall Cronbach alpha = 0.83). In phase II, 193 of the projected 200 patients have been enrolled and completed interviews. Initial results show strong test-retest reliability. IMPACT: The construction of an instrument designed to assess the quality of dying contributes to the provision of quality care for terminally ill veterans and their families. The instrument will provide an evaluation tool for VA administrators to assess the quality and effectiveness of interventions seeking to improve end of life care.
