Economic evaluation of home blood pressure telemonitoring: A randomized controlled trial

Abstract Aims. The purpose of the present study was to compare the costs of home blood pressure (BP) telemonitoring (HBPM) with the costs of conventional office BP monitoring. In a randomized controlled trial, 105 hypertensive patients performed HBPM and 118 patients received usual care with convent...

Description
Summary:Abstract Aims. The purpose of the present study was to compare the costs of home blood pressure (BP) telemonitoring (HBPM) with the costs of conventional office BP monitoring. In a randomized controlled trial, 105 hypertensive patients performed HBPM and 118 patients received usual care with conventional office BP monitoring during 6 months. Costs were quantified from the healthcare perspective. Non-parametric simulations were performed to quantify the uncertainty around the mean estimates and cost-effectiveness acceptability curves were made. Major findings. Systolic and diastolic daytime and night-time ambulatory BP (ABP) were reduced in both groups. The uncertainty around the incremental cost effectiveness ratio point estimates was considerable for both systolic and diastolic ABP. For systolic ABP, the difference in cost effectiveness ratio between the two groups was 256 Danish kroner (DKK)/mmHg [95% uncertainty interval, UI −860 to 4544]. For diastolic ABP, the difference in cost effectiveness ratio between the two groups was 655 DKK/mmHg [95% UI −674 to 69315]. Medication and consultation costs were lowest in the intervention group, but were offset by the cost of the telemonitoring equipment. Conclusions. Cost-effectiveness analysis showed that telemonitoring of home BP was more costly compared with usual monitoring of office BP. The cost-effectiveness result is surrounded with considerable uncertainty.
