Telemonitoring for chronic obstructive pulmonary disease: a cost and cost-utility analysis of a randomised controlled trial

We compared the costs and cost-effectiveness of telemonitoring vs usual care for patients with chronic obstructive pulmonary disease (COPD). A total of 256 patients were randomised to either telemonitoring or usual care. In the telemonitoring arm, the touch-screen telemonitoring equipment transmitted data to clinical teams monitoring the patients. Total healthcare costs were estimated over a 12-month period from a National Health Service perspective and quality adjusted life year (QALYs) were estimated by the EQ-5D tool. Telemonitoring was not significantly more costly than usual care (mean difference per patient 2065.90 pound (P<0.18). The increased costs were predominantly due to telemonitoring service costs and non-significantly higher secondary care costs. Telemonitoring for COPD was not cost-effective at a base case of 137,277 pound per QALY with only 15% probability of being cost-effective at the usual threshold of 30,000 pound per QALY. Although there was some statistical and methodological uncertainty in the measures used, telemonitoring was not cost-effective in the sensitivity analyses performed. It seems unlikely that a telemonitoring service of the kind that was trialled would be cost-effective in providing care for people with COPD.
