A multifaceted intervention that included interactive voice response technology had a positive effect on patients and also increased their likelihood of reaching their systolic BP goal compared with usual care.
The randomized study included 146 patients with uncontrolled hypertension who were split into two arms: those who were either treated with a BP intervention that involved interactive voice response technology, home BP monitoring and pharmacist-led BP management (n=78), or usual care (n=68).
After patient interviews, the researchers reported that 86% of the intervention patients vs. 62% of the usual-care patients had a positive experience with participation. This led to meaningful increases in the intervention group among patients who reached their systolic BP goal (68% vs. 55%).
According to researchers, six factors emerged that explained the improved results in the intervention arm: improved relationships with medical personnel; increased knowledge of hypertension; increased participation in their health care and personal empowerment; greater understanding of the effect of health behavior on BP; high satisfaction with technology used in the intervention; and, in some patients, increased health care utilization.
“When appropriately integrated, we believe this model will support patients to adhere to mutually agreed-on medical regimens,” the researchers wrote. “The findings from this study can provide the framework for the development of subsequent multifaceted interventions to change patient and health care provider behavior as well as clinical outcomes of patients with hypertension. This model may also inform interventions for other chronic conditions, such as diabetes.”
