Compliance measurement-guided medication management programs in hypertension : a systematic review
Objective: Whether interventions including measurement and correction of patients’ attitude to antihypertensive medication can improve hypertension management is unclear. The review aims to determine the effectiveness of patient compliance measurement-guided medication management (CMGM) programs in essential hypertension.   Design: Systematic review. Data sources: MEDLINE, EMBASE, CENTRAL, hypertension meetings abstracts, and bibliographies of identified articles.   Methods: Randomized controlled trials (RCT) and observational studies (OS) were assessed by 2 reviewers independently. Quality assessment was performed with the Cochrane risk of bias tool and evaluated in a four-point continuum. A narrative data synthesis was performed due to significant heterogeneity among studies. Results: 13 studies (8 RCT, 5 OS) involving 2150 hypertensives were included. Five trials of CMGM with electronic devices as a sole intervention suggested decrease in blood pressure (BP) but the result may have been due to bias. Short-term BP improvement under CMGM in complex interventions was revealed in 4 studies of low-to-moderate quality. In 4 integrated care studies of higher quality the impact of CMGM component was not possible to distil and may be compromised by medication regimens. Regular feedback to the treating physician seems to be an essential component of CMGM and may be effectively mediated by a nurse or a pharmacist and via telecommunication.  Conclusions: No convincing evidence for the effectiveness of CMGM as a health technology was found due to non-optimal study designs and methodological quality. Future research should follow accepted quality standards and current guidelines for the treatment of hypertension, include specific groups of patients with compliance problems and consider clinical, economic, patient-reported and organizational outcomes.
