RESUMEN
BACKGROUND: Atrial fibrillation is globally the most common sustained cardiac arrhythmia which increases patient morbidity and mortality, dramatically influencing well-being. Despite substantial efforts, an optimal clinical pathway for chronic atrial fibrillation management has yet to be developed. In recent practice, a multidisciplinary team management has been recommended for patients with atrial fibrillation. However, experiments exploring nurse-led multidisciplinary team management in chronic atrial fibrillation management relative to standard clinical management are still sparse and limited. OBJECTIVE: To evaluate the effects of a nurse-led multidisciplinary team approach on cardiovascular hospitalization and death, and quality of life in patients with atrial fibrillation. DESIGN: Randomized controlled trial. SETTING: The Cardiology Department of a tertiary referral hospital in Beijing, China. PARTICIPANTS: Eligible patients diagnosed with atrial fibrillation who consented. METHODS: Subjects were randomly assigned into one of two Cardiology Units upon admission. Patients in the control group (n = 119) received usual care and those in the intervention group (n = 116) underwent a nurse-led multidisciplinary team approach. Follow-up lasted for 12 months. The primary endpoint was a composite of cardiovascular hospitalization and cardiovascular death. The secondary endpoint was the differences in the quality of life between the groups observed at 6 months and 12 months of follow-up, compared to the baseline data, as determined using a Chinese version of the Medical Outcome Study Short-Form 36 General Health Survey. RESULTS: Patients under intervention showed a fewer cardiovascular hospitalization (17 vs. 35, p = 0.006) than those receiving usual care. Discernible differences were also observed in rates of cardiovascular hospitalization between the two groups (hazard ratio: 2.115, 95% confidential interval: 1.228-3.643, log-rank = 6.746, p = 0.009). Quality of life was improved in both groups, but more so in the intervention group (scores, 588.0 ± 106.0 vs. 519.1 ± 120.7 at 6 months and 674.4 ± 53.4 vs. 584.1 ± 105.9 at 12 months; both p < 0.001). Repeated measures analysis of variance indicated that group-by-time and between-subjects effects in respect of patients' quality of life (F = 9.310, p < 0.01; F = 29.042, p < 0.01, respectively). No relationships were found with cardiovascular death. CONCLUSIONS: Nurse-led multidisciplinary team management reduces cardiovascular hospitalization and improves quality of life in patients with atrial fibrillation, suggesting that this innovative management approach should be implemented in clinical practice.
