Office BP was measured according to a standardized protocol by a trained nurse with an electronic BP monitor (Omron HEM‐7121, Omron Healthcare Taiwan Co., Songshan, Taipei, Taiwan, ROC; Importation of Medical Device License 026021 by Ministry of Health and Welfare) in the morning after the participants had been instructed to sit for 10 min in a quiet room. Three consecutive BP measurements were obtained from the same upper arm, with each measurement taken at 30‐s intervals.
Patients were connected to an ambulatory BP monitoring device between 08:00 h and 10:00 h (WatchBP O3 ambulatory BP monitor, Microlife Corp., Neihu, Taipei, Taiwan, ROC; Medical Device License 004574 by Ministry of Health and Welfare). The device was programmed to record the BP every 15 min between 06:00 h and 22:00 h (daytime BP) and every 30 min from 22:00 h to 06:00 h (night‐time BP). The average of all the SBP/DBP readings was the 24‐h SBP/DBP, and the daytime and night‐time average SBP/DBP were also calculated. Normal dipping pattern presents nocturnal BP fall between 10% and 20%.¹² Patients were classified as extreme dippers (nocturnal BP fall ≥ 20%), dippers (≥10%–<20%), non‐dippers (≥0%–<10%), and reverse dippers (nocturnal BP increase > 0%).⁸

This study conducted experiments on 30 adults aged 20–50 years (14 men, 16 women) with wide ranging attributes (35.3 ± 12.5 years, height: 166.1 ± 9.4 cm, weight: 63.3 ± 12.8 kg). The subjects were selected from a group of people with no hypertension. The study was approved by the Public Institution Bioethics Committee designated by the Ministry of Health and Welfare of South Korea (IRB P01-201812-12-001).
In the experiments, the stable blood pressures of the subjects were measured simultaneously using the experimental sofa and a cuff-type blood pressure monitor (HEM-7121, Omron, Kyoto, Japan) after the subjects were given a sufficient rest. The blood pressure was measured five times at intervals of 1 min.

Measuring Hypertension Treatment and Control

The blood pressure was measured thrice with a one-minute gap using an electronic monitor (Omron model HEM-7121). Our study averaged the last two readings of the Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP). Based on the guidelines suggested by seventh report of the Joint National Committee on prevention, detection, evaluation, and treatment of high blood pressure (JNC-7), an individual was considered hypertensive if his/her average SBP was ≥ 140 mmHg or/and the average DBP was ≥ 90 mmHg or if the individual was using any antihypertensive medication at the time of the survey (Chobanian et al., 2003 (link)).
The outcome variables for the present study were MO for the treatment and control of HT. The prevalence of missed opportunity for the treatment of HT was defined as the proportion of untreated individuals among the self-reported hypertensive cases who reported that they are not hypertensive but in biometric measurement were found to be hypertensive, and had visited a public or private health facility in the preceding 12 months. On the other hand, the prevalence of MO for the control of HT was defined as the proportion of individuals with uncontrolled HT, among all the hypertensive cases, who had been consuming antihypertensive drugs at the time of the survey and had visited a public or private health facility in the preceding 12 months (See Fig. 1).

Participants presented to the laboratory between the hours of 6:00 AM and 9:00 AM, following an overnight fast, for measurement and sample collection. Height was determined to the nearest half centimetre using a wall-mounted stadiometer (Surgical & Medical Products). Body mass was determined using a digital body composition scale (model HBF-202; Omron Australia). Waist and hip circumference were assessed in accordance with the WHO STEPwise approach to surveillance protocols using a graduated anthropometric measuring tape (Seca). Blood pressure and pulse rate were determined using an automatic blood pressure monitor (model HEM-7121; Omron Australia) with individuals in a seated position.

Standardized Stepped-Care Hypertension Treatment

The study team and Ministry of Health officials designed a standardized stepped-care hypertension treatment protocol summarized in an algorithm, based on the American Heart Association (AHA) Hypertension Guidelines 2017 and the Guatemala Ministry of Health Healthcare Norms 2018 [22 , 23 ]. After participants are enrolled in the study, health district physicians, nurses, and auxiliary nurses will establish an individualized treatment plan for the participant to reach a BP target < 130/80 mmHg, with a combination of anti-hypertensive medications offered by the Ministry of Health: hydrochlorothiazide, enalapril and losartan. The study team provided educational materials and pocket cards summarizing the hypertension treatment algorithm to healthcare providers and an electronic BP monitor (Omron HEM-7121) to each health center and health post.

After study enrollment, each patient receiving care at one of the intervention health districts obtains an electronic home BP monitor that stores 30 readings with date and time stamp (Omron HEM-7121). Auxiliary nurses will teach patients and literate relatives to measure BP using the electronic monitor and document readings on a card provided by the study team. Auxiliary nurses will review the patient card and document mean home BP-readings during the health coaching sessions, which the care team will use to guide hypertension management decisions. Home BP monitoring is not part of usual hypertensive care.

From October 2017 to December 2017, the investigator collected the data. The 450 participants' houses were visited, and participants were interviewed with a pretested, semi-structured questionnaire with sociodemographic details. The Updated Kuppuswamy Scale was used to classify the participants based on their socioeconomic status.
[ 15 ] This was followed by recording of blood pressure with a calibrated standard blood pressure monitor (Omron HEM7121), weight by a calibrated digital weighing machine (Equinox), height, and waist circumference with a constant tension tape. After this, the participants were handed over a sterile urine culture bottle for collection of early morning urine sample the next day.

According to a standardized protocol, a well-trained nurse assessed the morning office BP using an electronic BP monitor (Omron HEM-7121, Omron Healthcare Taiwan Co., Songshan, Taipei, Taiwan, ROC) after the patients were instructed to sit for 10 min in a quiet room. During each measurement, both SBP and DBP were recorded. Three consecutive BP measurements were performed in the same upper arm. Each measurement was separated at an interval of 30 s. The average value of the last two measurements was considered the BP reading.

The secondary outcome measure was a change in systolic blood pressure (SBP) from session one after three (monthly) health coaching sessions provided by the community pharmacist. Blood pressure was measured using an automated blood pressure monitor (OMRON HEM-7121). Pharmacist health coach training included guidelines on blood pressure assessments. The guidelines stated that the participant should be seated with their feet flat on the floor, legs uncrossed, upper arm bare and with their back and arm supported. Two recordings were taken 1 minute apart, and the lower of the two recordings was recorded.
To support the outcomes of the dynamic SOC charts, health coaching participants also completed the Adherence to Refills and Medications Scale (ARMS) questionnaire, a validated self-report adherence scale [26 (link)]. The ARMS scale contains twelve questions to assess a participant’s medication adherence, which are divided into two categories, adherence with taking medications (eight items) and adherence with refilling prescriptions (four items). Each question is scored on a 4-point scale: 1 = none; 2 = some; 3 = most; 4 = all. Possible scores range from 12 to 48, with a lower score indicating greater adherence. The twelve-item scale has high internal consistency overall (Cronbach’s alpha = 0.80) [27 (link)]. The internal consistency of ARMS in this study was calculated to be 0.74.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
