Abstract

CONTEXT: There are few randomized controlled trials on the effectiveness of palliative care interventions to improve the care of patients with advanced cancer. OBJECTIVE: To determine the effect of a nursing-led intervention on quality of life, symptom intensity, mood, and resource use in patients with advanced cancer. DESIGN, SETTING, AND PARTICIPANTS: Randomized controlled trial conducted from November 2003 through May 2008 of 322 patients with advanced cancer in a rural, National Cancer Institute-designated comprehensive cancer center in New Hampshire and affiliated outreach clinics and a VA medical center in Vermont. INTERVENTIONS: A multicomponent, psychoeducational intervention (Project ENABLE [Educate, Nurture, Advise, Before Life Ends]) conducted by advanced practice nurses consisting of 4 weekly educational sessions and monthly follow-up sessions until death or study completion (n = 161) vs usual care (n = 161). MAIN OUTCOME MEASURES: Quality of life was measured by the Functional Assessment of Chronic Illness Therapy for Palliative Care (score range, 0-184). Symptom intensity was measured by the Edmonton Symptom Assessment Scale (score range, 0-900). Mood was measured by the Center for Epidemiological Studies Depression Scale (range, 0-60). These measures were assessed at baseline, 1 month, and every 3 months until death or study completion. Intensity of service was measured as the number of days in the hospital and in the intensive care unit (ICU) and the number of emergency department visits recorded in the electronic medical record. RESULTS: A total of 322 participants with cancer of the gastrointestinal tract (41%; 67 in the usual care group vs 66 in the intervention group), lung (36%; 58 vs 59), genitourinary tract (12%; 20 vs 19), and breast (10%; 16 vs 17) were randomized. The estimated treatment effects (intervention minus usual care) for all participants were a mean (SE) of 4.6 (2) for quality of life (P = .02), -27.8 (15) for symptom intensity (P = .06), and -1.8 (0.81) for depressed mood (P = .02). The estimated treatment effects in participants who died during the study were a mean (SE) of 8.6 (3.6) for quality of life (P = .02), -24.2 (20.5) for symptom intensity (P = .24), and -2.7 (1.2) for depressed mood (P = .03). Intensity of service did not differ between the 2 groups. CONCLUSION: Compared with participants receiving usual oncology care, those receiving a nurse-led, palliative care-focused intervention addressing physical, psychosocial, and care coordination provided concurrently with oncology care had higher scores for quality of life and mood, but did not have improvements in symptom intensity scores or reduced days in the hospital or ICU or emergency department visits.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
