Central blood pressure monitoring method oriented to wearable devices

Abstract BACKGROUND Guidelines recommend that patients with newly elevated office blood pressure undergo ambulatory blood pressure monitoring (ABPM) or home blood pressure monitoring (HBPM) to rule-out white coat hypertension before being diagnosed with hypertension. We explored patients’ perspectives of the barriers and facilitators to undergoing ABPM or HBPM. METHODS Focus groups were conducted with twenty English- and Spanish-speaking individuals from underserved communities in New York City. Two researchers analyzed transcripts using a conventional content analysis to identify barriers and facilitators to participation in ABPM and HBPM. RESULTS Participants described favorable attitudes toward testing including readily understanding white coat hypertension, agreeing with the rationale for out-of-office testing, and believing that testing would benefit patients. Regarding ABPM, participants expressed concerns over the representativeness of the day the test was performed and the intrusiveness of the frequent readings. Regarding HBPM, participants expressed concerns over the validity of the monitoring method and the reliability of home blood pressure devices. For both tests, participants noted that out-of-pocket costs may deter patient participation and felt that patients would require detailed information about the test itself before deciding to participate. Participants overwhelmingly believed that out-of-office testing benefits outweighed testing barriers, were confident that they could successfully complete either testing if recommended by their provider, and described the rationale for their testing preference. CONCLUSIONS Participants identified dominant barriers and facilitators to ABPM and HBPM testing, articulated testing preferences, and believed that they could successfully complete out-of-office testing if recommended by their provider.

Patient’S Experience

Introduction24-hour ambulatory blood pressure monitoring (ABPM) is the gold standard diagnostic method for hypertension, but has some shortcomings in clinical practice while clinical settings often lack sufficient devices to accommodate all patients with suspected hypertension. Home blood pressure monitoring (HBPM) and office blood pressure monitoring (OBPM) also have shortcomings, such as the white coat effect or a lack of accuracy. This study aims to study the validity of a new method of diagnosing hypertension consisting of monitoring blood pressure (BP) for 1 hour and comparing it with OBPM and HBPM and examining the sensitivity and specificity of this method compared with 24-hour ABPM. The patient experience will be examined in each method.Methods and analysisA minimum sample of 214 patients requiring a diagnostic test for hypertension from three urban primary healthcare centres will be included. Participants will undergo 24-hour ABPM, 1-hour BP measurement (1-BPM), OBPM for three consecutive weeks and HBPM. Patients will follow a random sequence to first receive 24-hour ABPM or 1-hour ABPM. Daytime 24-hour ABPM records will be compared with the other monitoring methods using the correlation coefficient and Bland Altman plots. The kappa concordance index and the sensitivity and specificity of the methods will be calculated. The patient’s experience will be studied, with selected indicators of efficiency and satisfaction calculated using parametric tests.Ethics and disseminationThe protocol has been authorised by the research ethics committee of the Hospital Clinic of Barcelona (Ref. HCB/2014/0615): protocol details and amendments will be recorded and reported to ClinicalTrials.com. The results will be disseminated in peer-reviewed literature, and to policy makers and healthcare partners.Trial registrationNCT03147573; Pre-results.

Beta Thalassemia Major

Introduction: There are very few studies on the effects of regular blood transfusions on the hemodynamic organization of patients with Beta-Thalassemia Major (BTM). Ambulatory Blood Pressure Monitoring is method that evaluates fluctuations in day-night periods and life cycle changes. In this study, we aimed to investigate the effects of blood transfusion on hemodynamic parameters by the Ambulatory Blood Pressure Monitoring method on the day of transfusion in patients with a diagnosis of Beta-Thalassemia Major. Material and Methods: This study was conducted in patients who were followed up with a diagnosis of BTM between June 2020 and July 2020. The study consisted of 30 patients. The blood pressure of the patients was measured by auscultation method on the morning of the day when they received routine red blood cell transfusion treatments, and the patients were fitted with an Ambulatory Blood Pressure Monitoring device. With Ambulatory Blood Pressure Monitoring, mean systolic blood pressure, diastolic blood pressure, heart rate, mean arterial pressure, values were calculated for each patient. Statistical analysis was performed by the IBM SPSS Statistics 21 package program. The significance limit for the p-value was accepted as <0.05. Results: There was a significant difference in mean systolic blood pressure and heart rate values between pre-transfusion, transfusion, and post-transfusion periods. In our study, the rate of white coat hypertension was 8.3%, and the rate of masked hypertension was 4.1%. It was observed that 67% of the patients were non-dippers, and the blood pressure burden of one patient was more than 25%. Conclusions: Measurement of hemodynamic parameters with Ambulatory Blood Pressure Monitoring is the gold standard in terms of detection and follow-up of non-dipper patients, indicating increased cardiovascular risk. In practice, Ambulatory Blood Pressure Monitoring should be used more in the follow-up of chronic patients.
