Using a survey of a cohort of primary care patients, the authors determined the proportion currently using home blood pressure monitoring (
HBPM) and calculated odds ratios (
ORs) of factors associated with such use. Overall, 530 questionnaires were received (80% response rate); 35.2% of respondents reported that their doctor had recommended
HBPM (95% confidence interval [CI], 31.1-39.3), and 43.1% reported currently using
HBPM (95% CI, 38.8-47.3). Compared with patients younger than 45 years, hypertensive patients older than 65 years were more likely to be using
HBPM (OR, 2.53; 95% CI, 1.20-5.33). Those with a history of
stroke/
transient ischemic attack were also more likely to use
HBPM (OR, 2.06; 95% CI, 1.00-4.24). Compared with patients with a level of
hypertension knowledge <10th percentile, those with a knowledge level >90th percentile were more likely to use
HBPM (OR, 1.96; 95% CI, 1.08-3.56). The factor most strongly associated with use of
HBPM was recalling a doctor's recommendation to do so (OR, 7.93; 95% CI, 4.96-12.7).
