Validity and reliability of 1-h automated office blood pressure measurement for the diagnosis of hypertension.

AIMS: The objective of this study was to examine the validity of 1 h automated office blood pressure measurement for the diagnosis of hypertension. METHODS: We included patients requiring a hypertension diagnostic test. Participants underwent ambulatory blood pressure monitoring, 1 h automated office blood pressure measurement, office blood pressure measurement and home blood pressure monitoring. The prevalence of hypertension and subtypes were calculated. Mean values of ambulatory blood pressure monitoring were compared with 1 h automated office blood pressure measurement using the correlation coefficient and Bland-Altman graphs. The Kappa concordance index, sensitivity, specificity and diagnostic accuracy were calculated, and the area under the receiver operating characteristic curve was used to establish the diagnostic threshold of the 1-h measurement. RESULTS: Of 562 participants, 438 (87.6%) completed the four diagnostic methods. The 1-h method had a sensitivity of 76.6 [95% confidence interval (95% CI): 71.1-81.5], a specificity of 64.8% (95% CI: 57-72.1) and the best diagnostic accuracy (72.1%, 95% CI: 67.7-76.3) compared with the office and home measurements. Moderate-high correlations were observed between DBP (r = 0.73) and SBP (r = 0.58) readings. The 1-h method classified more patients as normotensive (24.4%) and fewer patients with white-coat hypertension (13.3%). A diagnostic threshold of at least 133/83 mmHg for the 1-h method could improve diagnostic accuracy by 2.3%. CONCLUSION: One-hour automated blood pressure measurement is a valid, reliable method for the diagnosis of hypertension in undiagnosed patients. The diagnostic accuracy permits detection of white-coat and masked hypertension. To diagnose hypertension, the 1-h method or conventional home blood pressure monitoring should be used rather than office measurements.

Effectiveness of a new one-hour blood pressure monitoring method to diagnose hypertension: a diagnostic accuracy clinical trial protocol.

INTRODUCTION: 24-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 ANALYSIS: A 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 DISSEMINATION: The 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 REGISTRATION: NCT03147573; Pre-results.

Health care and therapeutic education program for newly diagnosed type 2 diabetes: A new approach in primary care. / Programa de atención y educación terapéutica en el debut de la diabetes tipo 2: un nuevo modelo de abordaje en atención primaria.

INTRODUCTION: Despite the favorable evidence available, our public health care system has no specific programs including therapeutic education for patients newly diagnosed with type 2 diabetes (T2DM), which would be crucial for the subsequent course of the disease. OBJECTIVES: To assess the effectiveness of a "Health care and Therapeutic Education Program for newly diagnosed type 2 diabetes (PAET-Debut DM2)" agreed by the primary care centers and the reference hospital in a given geographical area. METHODS: A prospective pilot study in patients over 18 years of age diagnosed with T2DM between February 2012 and 2013. The PAET-DebutDM2 is planned and set up in four primary care centers in the area covered by Hospital Clínic in Barcelona. Reference persons (family doctor and nurse) are designated at each center and specific training is provided to standardize the clinical processes and therapeutic education methods. First results are assessed and compared at 6 and 12 months. RESULTS: The program was proposed to 345 patients, of which 191 (55.3%) were enrolled in it and 134 (70.2%) completed the program. At the end of the program, 84% achieved the control goal (HbA1c <7%) and 88% passed the screening of chronic complications. Improvements were seen in body weight, physical activity (p<0,001), and disease awareness (p<0.05), and there were less hospital emergencies due to DM as compared to patients not included in the program (p=0.023). CONCLUSION: The PAET-DebutDM2 standardizes intervention and education and is effective in terms of clinical and educational results and patient satisfaction. The program emphasizes the importance of early education and intervention, reorganizing resources without increasing care pressure in the primary care centers, thus reducing hospital care.
