Abstract

Hypertension is a principal cause of mortality and morbidity in Singapore. The use of home blood-pressure monitoring (HBPM) to assess hypertensive control with digital devices in the local multi-racial population is unknown. The study determined the factors associated with hypertensive patients' use of HBPM in primary care in a multi-racial Asian population. Randomized cross-sectional questionnaire survey of hypertensive patients managed in a district polyclinic. A model predicting use of HBPM was constructed by univariate and multivariate logistic regression. A total of 224 eligible subjects were randomly selected from 1943 patients. Response rate was 78.1% (n = 175). In all, 61.7% of them were aware of HBPM but only 24% used HBPM. Using multivariate analysis by stepwise backward regression, the final fitted model showed that HBPM was associated with higher patients' socioeconomic status: (adjusted OR for middle-income status = 2.85, 95% CI: 1.2-6.78, P = 0.018; adjusted OR for high-income status = 3.46, 95% CI: 1.22-9.87, P = 0.020) and their documented diastolic BP (adjusted OR for diastolic BP > 80 mmHg = 2.26, 95% CI: 1.06-4.82, P = 0.034). Nonusers cited failure to recognize benefits (54.1%), lack of HBPM awareness (29.3%), understanding of device operation (18.8%) and perception of inaccuracy (10.5%) as deterrents. 76.2% of users were satisfied with HBPM but lacked knowledge in maintenance of devices. In conclusion, 61.7% of the study population were aware of HBPM but only 24% used it. Patients' failure to recognize benefits, lack of awareness, cost and perception of inaccuracy were barriers. Higher socioeconomic status and patient's documented diastolic BP correlated with HBPM usage.
