Rationale: Early detection of COPD exacerbations using tele-monitoring of physiological variables might reduce the frequency of hospitalisation. Objectives: To evaluate the efficacy of home monitoring of lung mechanics by the forced oscillation technique (FOT) and cardiac parameters in older COPD patients with co-morbidities.
Methods: This multicentre, randomized clinical trial recruited 312 GOLD grade II-IV COPD patients (median age 71 years [IQR:66-76], 49.6% grade II, 50.4% grade III-IV), with a history of exacerbation in the previous year and at least one non-pulmonary co-morbidity. Patients were randomised to usual care (n=158) or tele-monitoring (n=154) and followed for 9 months. All tele-monitoring patients self-assessed lung mechanics daily and in a subgroup with congestive heart failure (n=37) cardiac parameters were also monitored. An algorithm identified deterioration, triggering a telephone contact to determine appropriate interventions.
Measurements and Main results: Primary outcomes were time to first hospitalisation (TTFH) and change in EQ-5D utility index score. Secondary outcomes included: rate of antibiotic/corticosteroid prescriptions, hospitalisation, CAT, PHQ-9 and MLHF questionnaire scores, quality-adjusted life years and healthcare costs. Tele-monitoring did not affect TTFH, EQ-5D utility index score, antibiotic prescriptions, hospitalization rate and questionnaire scores. In an exploratory analysis, tele-medicine was associated with fewer repeat hospitalizations (-54%, p=0.017).
Conclusions: In older COPD patients with co-morbidities remote monitoring of lung function by FOT and cardiac parameters did not change TTFH and EQ-5D.
