Effects of a person-centred telephone-support in patients with chronic obstructive pulmonary disease and/or chronic heart failure – A randomized controlled trial

Purpose
To evaluate the effects of person-centred support via telephone in two chronically ill patient groups, chronic obstructive pulmonary disease (COPD) and/or chronic heart failure (CHF).
Method
221 patients ≥ 50 years with COPD and/or CHF were randomized to usual care vs. usual care plus a person-centred telephone-support intervention and followed for six months. Patients in the intervention group were telephoned by a registered nurse initially to co-create a person-centred health plan with the patient and subsequently to discuss and evaluate the plan. The primary outcome measure was a composite score comprising General Self-Efficacy (GSE), re-hospitalization and death. Patients were classified as deteriorated if GSE had decreased by ≥ 5 points, or if they had been re-admitted to hospital for unscheduled reasons related to COPD and/or CHF or if they had died.
Results
At six-month follow-up no difference in the composite score was found between the two study groups (57.6%, n = 68 vs. 46.6%, n = 48; OR = 1.6, 95% CI: 0.9–2.7; P = 0.102) in the intention-to-treat analysis (n = 221); however, significantly more patients in the control group showed a clinically important decrease in GSE (≥ 5 units) (22.9%, n = 27 vs. 9.7%, n = 10; OR = 2.8, 95% CI: 1.3–6.0; P = 0.011). There were 49 clinical events (14 deaths, 35 re-admissions) in the control group and 41 in the intervention group (9 deaths, 32 re-admissions). Per-protocol analysis (n = 202) of the composite score showed that more patients deteriorated in the control group than in the intervention group (57.6%, n = 68 vs. 42.9%, n = 36; OR = 1.8, 95% CI 1.0–3.2; P = 0.039).
Conclusion
Person-centred support via telephone mitigates worsening self-efficacy without increasing the risk of clinical events in chronically ill patients with CHF and/or COPD. This indicates that a patient-healthcare professional partnership may be established without the need for face-to-face consultations, even in vulnerable patient groups.
