Effect of telemonitoring on quality of life for patients with chronic obstructive pulmonary disease-A randomized controlled trial.

INTRODUCTION

Patients with chronic obstructive pulmonary disease (COPD) often experience severe physical limitations and psychological distress, which can lead to a deterioration in quality of life (QoL). Telemonitoring (TM) may improve QoL and reduce the number of hospitalizations and readmissions, but results from previous studies have been conflicting. The aim of this study was to assess the effect of TM on QoL in patients with moderate to severe COPD recruited during hospitalization for acute exacerbation (AECOPD).

METHODS

We conducted a randomized controlled trial at Silkeborg and Viborg Regional Hospitals in Denmark. Participants were recruited during hospitalization for AECOPD and randomized to a six-month telemonitoring service in addition to standard COPD care or standard COPD care alone. Patients were followed for 24 months. QoL was measured by the Hospital Anxiety and Depression Scale (HADS), and St Georges Respiratory Questionnaire (SGRQ) at 3-, 6-, 12-, and 24-months follow-up. The main outcome was QoL at 6 months.

RESULTS

In total, 101 patients were randomized to the TM intervention and 97 to standard care. The between-group difference in SGRQ at 6 months was -2.0 (-8.5; 4.5), in HADS-Anxiety -0.3 (-2.0; 1.4) and in HADS-depression 0.2 (-1.0; 1.4) corresponding to no significant difference in health-related QoL for patients receiving TM compared to standard care. No difference was seen at 12-24 months follow-up either.

DISCUSSION

TM in addition to standard care did not improve QoL in patients with moderate to severe COPD. Other means of improving management and QoL in severe COPD are urgently needed.
