Impact of Home Telemonitoring and Management Support on Blood Pressure Control in Nondialysis CKD: A Systematic Review and Meta-Analysis.

ABSTRACT:

Background

Hypertension is a major cause of cardiovascular disease, chronic kidney disease (CKD), and death. Several studies have demonstrated the efficacy of home blood pressure telemonitoring (HBPT) for blood pressure (BP) control and outcomes, but the effects of this intervention remain unclear in patients with CKD.

Objective

To determine the impact of HBPT on cardiovascular-related and kidney disease-related outcomes in patients with CKD.

Design

Systematic review and meta-analysis.

Setting

All studies that met our criteria regardless of country of origin.

Participants

Patients with chronic kidney disease included in studies using HBPT for BP assessment and control.

Measurements

Descriptive and quantitative analysis of our primary and secondary outcomes.

Methods

We searched MEDLINE, Embase, CINAHL Plus, PsycINFO, Cochrane CENTRAL, Web of Science, and gray literature from inception for observational and randomized controlled studies in nondialysis (ND) CKD using HBPT for BP control. We selected studies that used HBPT as intervention (with or without a control arm) for BP control in ND-CKD populations. The primary outcome was change in mean systolic BP (SBP) and mean diastolic BP (DBP).

Results

We selected 7 studies from 1669 articles that were initially identified. Overall, pooled estimates in the mean difference (MD) for SBP and DBP were -8.8 mm Hg; 95% confidence interval (CI): -16.2 to -1.4; P = .02 and -2.4 mm Hg; 95% CI: -3.8 to -1.0; P < .001, respectively. For studies comparing intervention with usual care (UC), pooled estimate in MD for SBP was -8.0 mm Hg (P = .02) with no significant reduction for DBP (-2.6 mm Hg; P = .18). In studies without a UC arm, both SBP and DBP were not significantly reduced (P > .05). The pooled estimate in MD for estimated glomerular filtration rate showed a significant improvement (5.4 mL/min/1.73 m²; P < .001).

Limitations

Heterogeneity and few available studies for inclusion limited our ability to identify a robust link between HBPT use and BP and kidney function improvement.

Conclusion

Home blood pressure telemonitoring is associated with mild lowering of BP and moderately improved kidney function in patients with CKD. However, larger studies with improved designs and prolonged interventions are still needed to assess the effects of HBPT on patients' outcomes.

Project description:ImportanceOnly about half of patients with high blood pressure (BP) in the United States have their BP controlled. Practical, robust, and sustainable models are needed to improve BP control in patients with uncontrolled hypertension.ObjectivesTo determine whether an intervention combining home BP telemonitoring with pharmacist case management improves BP control compared with usual care and to determine whether BP control is maintained after the intervention is stopped.Design, setting, and patientsA cluster randomized clinical trial of 450 adults with uncontrolled BP recruited from 14,692 patients with electronic medical records across 16 primary care clinics in an integrated health system in Minneapolis-St Paul, Minnesota, with 12 months of intervention and 6 months of postintervention follow-up.InterventionsEight clinics were randomized to provide usual care to patients (n = 222) and 8 clinics were randomized to provide a telemonitoring intervention (n = 228). Intervention patients received home BP telemonitors and transmitted BP data to pharmacists who adjusted antihypertensive therapy accordingly.Main outcomes and measuresControl of systolic BP to less than 140 mm Hg and diastolic BP to less than 90 mm Hg (<130/80 mm Hg in patients with diabetes or chronic kidney disease) at 6 and 12 months. Secondary outcomes were change in BP, patient satisfaction, and BP control at 18 months (6 months after intervention stopped).ResultsAt baseline, enrollees were 45% women, 82% white, mean (SD) age was 61.1 (12.0) years, and mean systolic BP was 148 mm Hg and diastolic BP was 85 mm Hg. Blood pressure was controlled at both 6 and 12 months in 57.2% (95% CI, 44.8% to 68.7%) of patients in the telemonitoring intervention group vs 30.0% (95% CI, 23.2% to 37.8%) of patients in the usual care group (P = .001). At 18 months (6 months of postintervention follow-up), BP was controlled in 71.8% (95% CI, 65.0% to 77.8%) of patients in the telemonitoring intervention group vs 57.1% (95% CI, 51.5% to 62.6%) of patients in the usual care group (P = .003). Compared with the usual care group, systolic BP decreased more from baseline among patients in the telemonitoring intervention group at 6 months (-10.7 mm Hg [95% CI, -14.3 to -7.3 mm Hg]; P<.001), at 12 months (-9.7 mm Hg [95% CI, -13.4 to -6.0 mm Hg]; P<.001), and at 18 months (-6.6 mm Hg [95% CI, -10.7 to -2.5 mm Hg]; P = .004). Compared with the usual care group, diastolic BP decreased more from baseline among patients in the telemonitoring intervention group at 6 months (-6.0 mm Hg [95% CI, -8.6 to -3.4 mm Hg]; P<.001), at 12 months (-5.1 mm Hg [95% CI, -7.4 to -2.8 mm Hg]; P<.001), and at 18 months (-3.0 mm Hg [95% CI, -6.3 to 0.3 mm Hg]; P = .07).Conclusions and relevanceHome BP telemonitoring and pharmacist case management achieved better BP control compared with usual care during 12 months of intervention that persisted during 6 months of postintervention follow-up.Trial registrationclinicaltrials.gov Identifier: NCT00781365.

Project description:Background:Pharmacist-managed (team-based) care for hypertension with home blood pressure monitoring support interventions have been widely studied and shown to be effective in improving rates of hypertension control and lowering blood pressure; however, few studies have evaluated the economic considerations related to bringing these programs into usual practice. Objective:To analyze the economic outcomes of the Blood Pressure Telemonitoring and Pharmacist Management on Blood Pressure (Hyperlink) study, a cluster randomized controlled trial which used home blood pressure telemonitoring and pharmacist case management to achieve better blood pressure control in patients with uncontrolled hypertension. Methods:A prospective analysis compared differences in medical costs and encounters in the Hyperlink telemonitoring intervention and usual care groups in the 12 months pre- and post-enrollment using medical and pharmacy insurance claims from a health care sector perspective. Generalized estimating equation models were used to estimate differences between groups over time. These results, combined with previously published prospective study results on intervention costs and blood pressure outcomes, were used to estimate cost-effectiveness measures for blood pressure control and reduction. Findings:Total medical costs in the intervention group were lower compared with the usual care group by an average of $281 per person, but this difference was not statistically significant. Clinic-based office visit, radiology, pharmacy, and hospital costs were also non-significantly lower in the intervention group. Statistically significant differences were found in lipid-related laboratory costs (higher) and in hypertension- (higher) and lipid-related (lower) pharmacy costs. Patterns in medical costs were similar for medical encounters. On average, the intervention cost $7337 per person achieving hypertension control and $139 or $265 per mm Hg reduction in systolic or diastolic blood pressure, respectively. Conclusions:Home blood pressure monitoring and pharmacist case management to improve hypertension care can be implemented without increasing, and potentially reducing, overall medical care costs.
