Feasibility and usability of an ontology-based mobile intervention for patients with hypertension

Mobile health interventions offer unique advantages and novel approaches to helping individuals manage hypertension. However, current interventions often lack theoretical and scientific grounding. The goal of this study, in which Can-Change member Dr. Michael Vallis took part, is to effectively model the knowledge, concepts and relationships relevant to the management of a chronic illness like hypertension, and to implement this knowledge model within a mobile self-management application that can be used by patients. The study concludes that it is possible to model existing information about the management of hypertension as an ontology. Given the nature of ontological models, this approach can be easily modified to address a variety of… Continue reading“Feasibility and usability of an ontology-based mobile intervention for patients with hypertension”

The Effect of a Reduction in Alcohol Consumption on Blood Pressure: A Systematic Review and Meta-analysis

Although it is well established that heavy alcohol consumption increases the risk of hypertension, little is known about the effect of a reduction of alcohol intake on blood pressure. We aimed to assess the effect of a reduction in alcohol consumption on change in blood pressure stratified by initial amount of alcohol consumption and sex in adults.

Adherence to Antihypertensive Medications: Current Status and Future Directions

Despite the proven clinical efficacy of antihypertensive medications to control BP, approximately half of treated patients are nonadherent. Barriers to antihypertensive medication adherence are numerous and include patient-related, provider-related, therapy-related, and system-related influences. This review, authored in part by Can-Change members Dr. Kim Lavoie and Dr. Tavis Campbell summarizes the current understanding of the prevalence and impact of the failure to adhere to the medical management of hypertension. Factors linked to improved adherence and studies that assessed strategies to improve adherence are also summarized.
