摘要: OBJECTIVE: To characterize chronic obstructive pulmonary disease (COPD) over patients' last 6 months of life. STUDY DESIGN: A retrospective analysis a prospective cohort from the Study to Understand Prognoses and Preferences for Outcomes Risks Treatments (SUPPORT). SETTING: Hospitalization exacerbation COPD at five US teaching hospitals. PARTICIPANTS: patients who died within 1 year (n = 416) among 1016 enrolled. METHODS: Interview medical record data were organized into time windows beginning with death ending earlier. OUTCOME MEASURES: Days in hospital, prognosis, illness severity, function, symptoms, preferences, impacts on families. RESULTS: One-year survival was 59%, 39% had ≥3 comorbidities, 15 25% hospitals. Exacerbation etiologies included respiratory infection (47%) cardiac problems (30%). Better quality life predicted longer (ARR: 0.36; 95% CI, 0.19- 0.87) as did heart failure etiology 0.57; 0.40, 0.82). Estimates by physicians prognostic model well calibrated, although worst prognoses survived than predicted. Patients' estimates prognosis poorly calibrated. One-quarter serious pain throughout, two-thirds dyspnea. illnesses major impact more families. preferences Do-Not-Resuscitate orders increased 40% 3 before 77% month death; their decisions not use mechanical ventilation 12 31%, resuscitation decreased 52 23%. CONCLUSIONS: Patients advanced often die have substantial comorbidities symptoms. Adequate description anchors improved care.
