Does integrated care based on teletransmitted home blood pressure improve daytime ambulatory blood pressure normalization in uncontrolled mild-moderate hypertensive patients?
Home blood pressure telemonitoring significantly improves daytime ambulatory blood pressure normalization compared to usual office-based care in patients with mild-moderate hypertension.
Absolute Event Rate: 62% vs 50%
p-value: p=< 0.05
BACKGROUND: Self blood pressure monitoring at home may improve blood pressure control and patients' compliance with treatment, but its implementation in daily practice faces difficulties. Teletransmission facilities may offer a more efficient approach to long-term home blood pressure monitoring. METHODS: Twelve general practitioners screened 391 consecutive uncontrolled mild-moderate hypertensive patients (80% treated), 329 of whom (58 +/- 11 years, 54% men) were randomized to either usual care on the basis of office blood pressure (group A, n = 113) or to integrated care on the basis of teletransmitted home blood pressure (group B, n = 216). Twenty-four-hour ambulatory blood pressure monitoring was performed at baseline and after 6 months, during which treatment was optimized according to either office (group A) or home (group B) blood pressure values. We compared differences between groups in the rate of daytime ambulatory blood pressure normalization (<130/80 mmHg), need of treatment changes during follow-up, quality of life scores, and healthcare costs. RESULTS: Baseline office blood pressures were 149 +/- 12/89 +/- 9 and 148 +/- 13/89 +/- 7 mmHg in groups A (n = 111) and B (n = 187) respectively, the corresponding daytime values being 140 +/- 11/84 +/- 8 and 139 +/- 11/84 +/- 8 mmHg. The percentage of daytime blood pressure normalization was higher in group B (62%) than in group A (50%) (P < 0.05). There were less frequent treatment changes in group B than in group A (9 vs. 14%, P < 0.05). Quality of life tended to be higher and costs lower in group B. CONCLUSION: Patients' management based on home blood pressure teletransmission led to a better control of ambulatory blood pressure than with usual care, with a more regular treatment regimen.
Parati et al. (2008) conducted an RCT in uncontrolled mild-moderate hypertension (n=329). Integrated care based on teletransmitted home blood pressure vs. Usual care based on office blood pressure was evaluated on rate of daytime ambulatory blood pressure normalization (<130/80 mmHg) (p=< 0.05). Integrated care based on home blood pressure teletransmission improved daytime ambulatory blood pressure normalization compared to usual care (62% vs 50%, P<0.05).
