Cost-Utility of an Objective Biochemical Measure to Improve Adherence to Antihypertensive Treatment.

Abstract

Nonadherence to antihypertensive medications is known to be a major health problem. Novel biochemical analyses using liquid chromatography-tandem mass spectrometry are becoming accepted as a clinically useful objective measure to manage (non)adherence in Hypertension Clinics. Discussion of results from such analyses with patients can significantly improve adherence and blood pressure control. Our objective was to model the cost-effectiveness of performing liquid chromatography-tandem mass spectrometry-based analyses in improving adherence in patients with hypertension. Lifetime cost-utility was assessed from a UK healthcare payer perspective, using a Markov model. Efficacy was based on study..
