Urinary proteomics combined with home blood pressure telemonitoring for health care reform trial: rational and protocol.

BACKGROUND: Hypertension and diabetes cause chronic kidney disease (CKD) and diastolic left ventricular dysfunction (DVD) as forerunners of disability and death. Home blood pressure telemonitoring (HTM) and urinary peptidomic profiling (UPP) are technologies enabling prevention. METHODS: UPRIGHT-HTM (Urinary Proteomics Combined with Home Blood Pressure Telemonitoring for Health Care Reform [NCT04299529]) is an investigator-initiated 5-year clinical trial with patient-centred design, which will randomise 1148 patients to be recruited in Europe, sub-Saharan Africa and South America. During the whole study, HTM data will be collected and freely accessible for patients and caregivers. The UPP, measured at enrolment only, will be communicated early during follow-up to 50% of patients and their caregivers (intervention), but only at trial closure in 50% (control). The hypothesis is that early knowledge of the UPP risk profile will lead to more rigorous risk factor management and result in benefit. Eligible patients, aged 55-75 years old, are asymptomatic, but have ≥5 CKD- or DVD-related risk factors, preferably including hypertension, type-2 diabetes, or both. The primary endpoint is a composite of new-onset intermediate and hard cardiovascular and renal outcomes. Demonstrating that combining UPP with HTM is feasible in a multicultural context and defining the molecular signatures of early CKD and DVD are secondary endpoints. EXPECTED OUTCOMES: The expected outcome is that application of UPP on top of HTM will be superior to HTM alone in the prevention of CKD and DVD and associated complications and that UPP allows shifting emphasis from treating to preventing disease, thereby empowering patients.

Understanding Moderators of Home Blood Pressure Telemonitoring Systems in Urban Hypertensive Patients: A Systematic Review and Meta-Analysis.

Background: Factors affecting the effectiveness of telemonitoring in home blood pressure telemonitoring (HBPT) must be examined in an integrated analysis in urban hypertensive patients. Materials and Methods: In a systematic review of electronic databases, we retrieved 1,433 citations and selected 34 comparisons. Specified moderators were the duration of the intervention, the frequency of remote transmission of blood pressure (BP) data, the additional intervention, and the intervention pathway. Results: For the duration of follow-up of HBPT, the weighted mean difference (WMD) in systolic blood pressure (SBP) between two groups was 11.900 mmHg (p-value <0.001) at 2 months and 3.024 mmHg (p = 0.002) at 12 months. The WMD in SBP was 5.512 mmHg (p < 0.001) in cases where data were transmitted daily and 1.818 mmHg (p = 0.084) for monthly transmission. For the group in which further interventions with HBPT were conducted, the WMD in SBP was 3.813 mmHg (p < 0.001). For patients who did not receive additional interventions, the WMD was 2.747 mmHg (p = 0.005). For the pathway of HBPT, the WMD was 6.800 mmHg (p = 0.053) when BP values were remote transmitted through letter, 3.041 mmHg (p = 0.001) through mobile phone/web, 2.224 mmHg (p = 0.043) through telephone-linked computer system, and 4.352 mmHg (p < 0.001) through telephone. Conclusions: The effects of moderators of HBPT systems utilized with urban hypertensive patients differ from those in interventions that did not distinguish urban from rural areas. Results for duration of implementation and frequency of data transmission were significant. Among the interventions using telecommunications, the telephone was the most effective in comparison to other channels.

Urinary proteomics combined with home blood pressure telemonitoring for health care reform trial-First progress report.

High blood pressure (BP) and type-2 diabetes (T2DM) are forerunners of chronic kidney disease and left ventricular dysfunction. Home BP telemonitoring (HTM) and urinary peptidomic profiling (UPP) are technologies enabling risk stratification and personalized prevention. UPRIGHT-HTM (NCT04299529) is an investigator-initiated, multicenter, open-label, randomized trial with blinded endpoint evaluation designed to assess the efficacy of HTM plus UPP (experimental group) over HTM alone (control group) in guiding treatment in asymptomatic patients, aged 55-75 years, with ≥5 cardiovascular risk factors. From screening onwards, HTM data can be freely accessed by all patients and their caregivers; UPP results are communicated early during follow-up to patients and caregivers in the intervention group, but at trial closure in the control group. From May 2021 until January 2023, 235 patients were screened, of whom 53 were still progressing through the run-in period and 144 were randomized. Both groups had similar characteristics, including average age (62.0 years) and the proportions of African Blacks (81.9%), White Europeans (16.7%), women 56.2%, home (31.2%), and office (50.0%) hypertension, T2DM (36.4%), micro-albuminuria (29.4%), and ECG (9.7%) and echocardiographic (11.5%) left ventricular hypertrophy. Home and office BP were 128.8/79.2 mm Hg and 137.1/82.7 mm Hg, respectively, resulting in a prevalence of white-coat, masked and sustained hypertension of 40.3%, 11.1%, and 25.7%. HTM persisted after randomization (48 681 readings up to 15 January 2023). In conclusion, results predominantly from low-resource sub-Saharan centers proved the feasibility of this multi-ethnic trial. The COVID-19 pandemic caused delays and differential recruitment rates across centers.

Multi-trajectory modeling of home blood pressure telemonitoring utilization among hypertensive patients in China: A latent class growth analysis.

BACKGROUND: Home blood pressure telemonitoring (HBPT) has great potential in improving blood pressure (BP) control among patients with hypertension. However, the longitudinal use trajectories of HBPT have not been identified yet. In addition, there has been a lack of understanding of the relationship between developmental trajectories of HBPT and BP control over time. The primary goal of this study was to identify the longitudinal trajectories of using HBPT among hypertensive patients and to explore the relationship between longitudinal trajectories of HBPT use patterns and BP control. METHODS: A total of 122 hypertensive patients were enrolled consecutively in Xiling, Huayan, Baisha and Xueyuan communities in Yichang City, Hubei Province, China. Each patient was provided with a portable monitoring device which has unlimited data service at the time of enrollment. Socio-demographics (e.g. name, age, sex, marital status) were collected at baseline. Real-time data including systolic and diastolic blood pressure were automatically uploaded to cloud platform through devices. Latent class growth analysis was conducted to determine the latent trajectory of HBPT use. Joint trajectory method was used to correlate the longitudinal trajectories of HBPT utilization and BP control status. RESULTS: Five trajectories were identified which are persistently low (47.1%), moderate with decreasing (23.9%), sharply decreasing (11.2%), high with decreasing (11.3%) and persistently high with increasing (6.6%). There was no statistically significant difference among 5 trajectories in the baseline survey in terms of age, marital status, BP (both SBP and DBP) and BP control status. However, there was a strong positive correlation between the HBPT utilization pattern and BP control status over time. CONCLUSIONS: The latent trajectories of HBPT utilization were identified in our study. However, no predictors of trajectory membership were identified. Nevertheless, we have demonstrated that HBPT was to some extent positively correlated with improved BP control, and this correlation still needs to be further proved.

The Role of Home Blood Pressure Telemonitoring for Blood Pressure Control.

Despite improvements in hypertension awareness and treatment, the blood pressure (BP) control rate still remains at around 50%. One of the major determinants of low BP control results from therapeutic inertia of the physician and suboptimal compliance of the patients. Home BP self-measurement and monitoring improves patients' awareness and helps the management of hypertension. Recent technological advances are allowing for accurate measurement and telemonitoring of home BP, with a number of randomized clinical trials demonstrating the efficacy of telemonitoring for BP control. Home BP telemonitoring combined with self-adjustment based on prespecified treatment algorithms has been shown to improve BP control. Additionally, telemonitoring with active intervention by medical professionals has been shown to improve drug compliance and increase the target BP achievement rate. Although nothing can replace the tried and tested doctor-patient relationship in the office, telemonitoring of home BP will be an important tool for treating hypertension in the future.

The pharmacist and the management of arterial hypertension: the role of blood pressure monitoring and telemonitoring.

Randomized controlled trials have documented that a team of health care professionals which includes a physician, a nurse and a community pharmacist may improve the benefit and adherence of anti-hypertensive therapy. If such a health care model relies on blood pressure telemonitoring, it can promote a stronger relationship between health care professionals and patients, and further improve BP control of hypertension. The major benefit of this collaborative approach is to center the patient's management in a tailored way, providing comprehensive and preventive care based on health information technologies. In this review, the authors summarize recent clinical studies that evaluate the role of the community pharmacist in BP measurements, and in hypertension screening and control. The authors also describe the advantages of using blood pressure telemonitoring in home and ambulatory settings to evaluate potential alternatives to primary care in hypertension management.
