An integrated program with home blood-pressure monitoring and village health volunteers for treating poorly controlled hypertension at the primary care level in an urban community of Thailand

Task-sharing with community health workers to treat hypertension: a scoping review

Many studies have implemented and evaluated task-sharing interventions with community health workers (CHWs) to manage hypertension. To identify gaps in research, we conducted a scoping review. We searched original articles published in PubMed and EMBASE between 2010 and 2022 and found 122 articles meeting our inclusion criteria. Only seven articles were from low-income countries (LICs), most of which were qualitative studies or mixed methods studies. In the identified 122 articles, CHWs often performed health education (61.3%) and measured blood pressure (60.4%). Whereas CHWs carried out pharmacological treatment in only three studies. Participant homes (75.0%) were the most common setting for receiving interventions. Our study identified specific needs for future research, specifically, studies in LICs that are experimental in design and that collect relevant qualitative information, and studies in which CHWs do advanced task. In addition, publications of CHW studies should provide a more comprehensive list of intervention features.

Machine learning models identify micronutrient intake as predictors of undiagnosed hypertension among rural community-dwelling older adults in Thailand: a cross-sectional study

Objective

To develop a predictive model for undiagnosed hypertension (UHTN) in older adults based on five modifiable factors [eating behaviors, emotion, exercise, stopping smoking, and stopping drinking alcohol (3E2S) using machine learning (ML) algorithms.

Methods

The supervised ML models [random forest (RF), support vector machine (SVM), and extreme gradient boosting (XGB)] with SHapley Additive exPlanations (SHAP) prioritization and conventional statistics (χ2 and binary logistic regression) were employed to predict UHTN from 5,288 health records of older adults from ten primary care hospitals in Thailand.

Results

The χ2 analyses showed that age and eating behavior were the predicting features of UHTN occurrence. The binary logistic regression revealed that taking food supplements/vitamins, using seasoning powder, and eating bean products were related to normotensive and hypertensive classifications. The RF, XGB, and SVM accuracy were 0.90, 0.89, and 0.57, respectively. The SHAP identified the importance of salt intake and food/vitamin supplements. Vitamin B6, B12, and selenium in the UHTN were lower than in the normotensive group.

Conclusion

ML indicates that salt intake, soybean consumption, and food/vitamin supplements are primary factors for UHTN classification in older adults.

A qualitative study on knowledge, attitude, and practice (KAP) toward swine influenza, information on pig farms and zoonosis reporting systems in Thailand

This qualitative study aimed to determine knowledge, attitudes, and practices (KAP) on swine influenza (SIV) among pig farm owners, pig farm workers, community leaders, public health personnel, and villagers who lived nearby pig farms in the northeastern (Nakhon Ratchasima), northern (Chiang Mai), and central (Nakhon Pathom) provinces of Thailand during May to December 2022. The qualitative information was collected from 91 respondents, including 33 individuals who participated in key informant interviews (KIIs) and 58 individuals who joined ten focus group discussions (FGDs) (5-7 persons per FGD). Our results showed that pig farmers, farm workers, and villagers lacked SIV-related knowledge and did not employ preventive measures. Some respondents had limited access to information about causes, clinical symptoms, treatment, and appropriate practices resulting in inadequate knowledge, attitudes, and practices regarding zoonotic diseases, especially SIV. Some pig farmers and farm workers reported seeking information about SIV infection from various sources; however, relevant authorities lacked dissemination of information regarding SIV to community members. The study suggested that healthcare personnel and relevant agencies should adopt a community-based approach to prevent swine influenza. This can be achieved by organizing health education and community communication interventions and involving those who have had contact with pigs or reside near pig farms. This will help increase community awareness and knowledge of swine influenza.

Evaluation of a depression care model for the hill tribes: a family and community-based participatory research

BACKGROUND

Even though, there is a particularly high prevalence of depression among individuals from the hill tribes in northern Thailand, they are unable to receive appropriate intervention due to cultural, transportation, communication, and legal barriers. Using community-based participatory research (CBPR), a depression care model was developed for the hill tribe population. The effectiveness of this model was examined using questionnaires, observations, focus groups, and in-depth interviews.

METHODS

Participants include people with depression (n = 17) who were chosen based on their mild to moderately severe depression scores on the Patient Health Questionnaire 9-item (PHQ-9 scores of 5-19) and their caregivers (n = 5). The in-depth interview was conducted to distinguish the selected participants into two groups. The first group, the self-help group program, consisted of 12 participants endorsing negative thoughts about themselves and inappropriate problems solving. The second group, the family camp program, had ten participants, including five patients with family-related issues and their family members. Subjects separately participated in either the self-help or the family groups over three weeks. They completed the PHQ-9 at the beginning and end of the intervention. Questionnaires, observations, focus groups, and in-depth interviews were used to evaluate the effectiveness of the model. Content analysis was used to examine the qualitative data. Wilcoxon signed-rank test was used to analyze the changes in the severity of depression before and after participation in the intervention.

RESULTS

The depression scores on the PHQ-9 of 12 participants improved significantly (11.92 ± 1.08 vs. 3.08 ± 0.51; p = 0.002) following participation in the self-help group. Increased self-esteem and improved interpersonal relationships were reported by participants in the self-help group program during interviews. There was no significant difference in the depression scores of 10 participating in the family camp program (6.00 ± 3.83 to 5.30 ± 3.56; p = 0.161).

CONCLUSION

A model for depression care was tested in a hill tribe community, and its effectiveness was clearly observed. The developed model can be applied to other hill tribe communities in northern Thailand to improve depression care.

Improving quality of non-communicable disease services at primary care facilities in middle-income countries: A scoping review

Health systems in middle-income countries face important challenges in managing the high burden of Non-Communicable Diseases (NCD). Primary health care is widely recognized as key to managing NCDs in communities. However, the effectiveness of this approach is limited by poor quality of care (QoC), among others. This scoping review identifies the types of interventions that have been used in middle-income countries to improve the quality of NCD services at primary care facilities. Further, it identifies the range of outcomes these quality interventions have influenced. This scoping review covered both the grey and peer-reviewed literature. The 149 articles reviewed were classified into four domains - governance, service-delivery systems, health workforce, and patients and communities. There was a remarkable unevenness in the geographic distribution of studies - lower middle-income countries and some regions (Middle East, North Africa, and South East Asia) had a scarcity of published studies. NCDs such as stroke and cardiovascular disease, mental health, cancer, and respiratory disorders received less attention. The thrust of quality interventions was directed at the practice of NCD care by clinicians, facilities, or patients. Few studies provided evidence from interventions at the organizations or policy levels. Overall, effectiveness of quality interventions was mixed across domains. In general, positive or mixed effects on provider clinical skills and behavior, as well as, improvements in patient outcomes were found across interventions. Access to care and coverage of screening services were positively influenced by the interventions reviewed. This review shows that quality improvement interventions tried in middle-income countries mostly focused at the provider and facility level, with few focusing on the organizational and policy level. There is a need to further study the effectiveness of organizational and policy level interventions on the practice and outcomes of NCD care.

Digital health interventions for non-communicable disease management in primary health care in low-and middle-income countries

Current evidence on digital health interventions is disproportionately concerned with high-income countries and hospital settings. This scoping review evaluates the extent of use and effectiveness of digital health interventions for non-communicable disease (NCD) management in primary healthcare settings of low- and middle-income countries (LMICs) and identifies factors influencing digital health interventions' uptake. We use PubMed, Embase, and Web of Science search results from January 2010 to 2021. Of 8866 results, 52 met eligibility criteria (31 reviews, 21 trials). Benchmarked against World Health Organization's digital health classifications, only 14 out of 28 digital health intervention categories are found, suggesting critical under-use and lagging innovation. Digital health interventions' effectiveness vary across outcomes: clinical (mixed), behavioral (positively inclined), and service implementation outcomes (clear effectiveness). We further identify multiple factors influencing digital health intervention uptake, including political commitment, interactivity, user-centered design, and integration with existing systems, which points to future research and practices to invigorate digital health interventions for NCD management in primary health care of LMICs.

Physicians' and nurses' perspective on chronic disease care practices in Primary Health Care in Brazil: a qualitative study

BACKGROUND

Primary health care-oriented systems provide better healthcare, especially for chronic diseases. This study analyzed the perspectives of physicians and nurses performing care for patients with chronic diseases in Primary Health Care in a Brazilian city.

METHODS

A qualitative study was conducted in Vitória da Conquista, Bahia, Brazil, using semi-structured interviews with five physicians and 18 nurses. The interview included questions from an analytical matrix based on three dimensions of healthcare practices: organizational, technical care, and biopsychosocial, following a deductive approach. The interviews were fully transcribed and analyzed using a thematic categorical approach.

RESULTS

The results indicated that the provision of chronic care occurs in a comprehensive way. Potentialities were identified in the diversification of access, offer of care actions and technologies, integration of teamwork, and bringing together social networks to foster autonomy and self-care. Weaknesses were mostly related to the high number of people in the teams, follow-up of several cases, high turnover of support teams, low integration of Primary Health Care with other levels, difficulties in intersectoral articulation and family participation in care.

CONCLUSION

The multidimensional assessment of health care practices aimed at individuals with chronic noncommunicable diseases was useful to portray the strengths and weaknesses of the services. It also ratifies the need to consider the importance of and investment in primary health care by offering the necessary technical, political, logistical and financial support to the units, to ensure the sustainability of the actions by nurses, doctors and entire team.

Interventions in hypertension: systematic review and meta-analysis of natural and quasi-experiments

BACKGROUND

Hypertension is an urgent public health problem. Consistent summary from natural and quasi-experiments employed to evaluate interventions that aim at preventing or controlling hypertension is lacking in the current literature. This study aims to summarize the evidence from natural and quasi-experiments that evaluated interventions used to prevent or control hypertension.

METHODS

We searched PubMed, Embase and Web of Science for natural and quasi-experiments evaluating interventions used to prevent hypertension, improve blood pressure control or reduce blood pressure levels from January 2008 to November 2018. Descriptions of studies and interventions were systematically summarized, and a meta-analysis was conducted.

RESULTS

Thirty studies were identified, and all used quasi-experimental designs including a difference-in-difference, a pre-post with a control group or a propensity score matching design. Education and counseling on lifestyle modifications such as promoting physical activity (PA), promoting a healthy diet and smoking cessation consultations could help prevent hypertension in healthy people. The use of computerized clinical practice guidelines by general practitioners, education and management of hypertension, the screening for cardiovascular disease (CVD) goals and referral could help improve hypertension control in patients with hypertension. The educating and counseling on PA and diet, the monitoring of patients' metabolic factors and chronic diseases, the combination of education on lifestyles with management of hypertension, the screening for economic risk factors, medical needs, and CVD risk factors and referral all could help reduce blood pressure. In the meta-analysis, the largest reduction in blood pressure was seen for interventions which combined education, counseling and management strategies: weighted mean difference in systolic blood pressure was - 5.34 mmHg (95% confidence interval [CI], - 7.35 to - 3.33) and in diastolic blood pressure was - 3.23 mmHg (95% CI, - 5.51 to - 0.96).

CONCLUSIONS

Interventions that used education and counseling strategies; those that used management strategies; those that used combined education, counseling and management strategies and those that used screening and referral strategies were beneficial in preventing, controlling hypertension and reducing blood pressure levels. The combination of education, counseling and management strategies appeared to be the most beneficial intervention to reduce blood pressure levels.

Disparity between knowledge and practice regarding COVID-19 in Thailand: A cross-sectional study of older adults

The efficacy of the public health measures to mitigate COVID-19 is influenced by health literacy which includes the level of knowledge about the disease and the preventive behaviours adopted by individuals. Thailand, being a low- and middle-income country with an ageing society, has to consider both the challenges that its health system has in disseminating information and the disparities in health literacy among its older population. This study investigated the knowledge and behaviour of older adults in Thailand regarding COVID-19 using the Impact of COVID-19 on Older Persons in Thailand, a cross-sectional survey. The data was primarily collected online and included 1,230 adults aged at least 60 years from nine provinces of the five regions of the country. The associated factors with the health literacy outcomes were tested using bivariate logistic regression analyses. It was observed that 43% of the older adults in the sample had proper knowledge of the disease and 33% adopted preventive behaviours. Knowledge about the disease was not associated with preventive behaviour. The associated factors common between the increased levels of knowledge and adoption of behaviours were rural area residence and higher educational attainment levels. Obtaining information from the internet was observed to increase knowledge while having the television and radio as sources of information had negative relationship. Many older adults continued to be employed during the lockdown period and this was associated with decreased adoption of preventive behaviour. The context of vulnerable populations, particularly older adults, is different with regard to their access to information and concern about income. Health information has to be tailored for targeted populations. Their needs also have to be addressed as they have increased risks because of financial and health susceptibilities.

Intervention Based on Integration of Health Literacy and Health Outcomes in Hypertension “A Systematic Review”

BACKGROUND: Hypertensive patients with low health literacy rarely visit health services, therefore, they have more chances of being hospitalized in comparison with those having a more adequate health literacy. AIM: This article aims to identify intervention based on integration of health literacy and its outcome in hypertensive patients. METHODS: Articles were searched using four bibliographic databases, namely, ProQuest, Science Direct, PubMed, and Google Scholar. PRISMA 2015 is used as a guideline for determining which articles are selected, one of the criteria being published on 2011–2021. RESULTS: A total of 25,264 articles were obtained from the four databases. Seven articles were selected after the extraction and incorporation of the inclusion criteria. The health outcomes of hypertension sufferers after receiving intervention based on integration of health literacy were divided into three groups; medical health outcomes, health literacy skills, and hypertension self-management behavioral. CONCLUSION: An intervention integrated with health literacy and considering the hypertensive patient health literacy in its own will increase the health outcomes of hypertensive patient.

Knowledge-Behavior Gap on COVID-19 among Older People in Rural Thailand

This study analyzed the difference between rural and urban older adults in Thailand regarding the relationship between the knowledge and behavior toward the prevention of contracting COVID-19. Path analysis was used to observe if the performance of protective behaviors was affected by the level of knowledge that older people have about the disease. This study used the Impact of COVID-19 on Older Persons in Thailand survey collected across the five regions of the country.

Rural residents benefited from community network of village health volunteers who provided information during the pandemic but, they had disadvantages on accessing newer media sources, mainly the internet, for the latest developments on COVID-19. Rural older adults had a higher level of knowledge about COVID-19 than those in urban areas; no difference was observed regarding their behavior to prevent themselves from being infected. The knowledge-behavior gap was viewed as a mechanism of cognitive avoidance because of overwhelming unprecedented information.

Effectiveness of a Multidisciplinary Approach Intervention to Improve Blood Pressure Control Among Elderly Hypertensive Patients in Rural Thailand: A Quasi-Experimental Study

Purpose

Uncontrolled blood pressure among Thai elderly hypertensive patients is a significant public health issue in primary health care facilities under the Universal Health Coverage Scheme in Thailand. This study examines the effectiveness of a multidisciplinary approach intervention to improve blood pressure control among elderly persons in rural Thailand.

Patients and Methods

This was quasi-experimental study conducted on 200 elderly persons who receive care for hypertension at primary health care facility in rural areas of Thailand. Participants were assigned to either the intervention or control groups. The intervention group was subjected to a multidisciplinary approach intervention program. This program included community-based care for hypertension, family-supportive care for hypertension, antihypertension medication adherence education program, the use of a reminder electronic pill box, and monthly pill counts and blood pressure measurements. The intervention continued for three months. The control group received care for hypertension at the hypertension clinic of the health center. Three measurements were taken at baseline, one month, and three months after the intervention. Data analysis included descriptive statistics and independent sample t-tests. Repeated-measure analysis of variance (ANOVA) and analysis of covariance (ANCOVA) were used to compare the differences between the two groups.

Results

At one month and three months after the intervention, the multidisciplinary approach intervention controlled blood pressure more effectively compared with the control group. Furthermore, the intervention group had lower systolic and diastolic blood pressure compared with the control group (P-value < 0.001).

Conclusion

These results suggest that the multidisciplinary approach intervention can be effective in controlling blood pressure in elderly hypertensive patients. Future studies should investigate a cost-effective means of integrating multidisciplinary approach interventions in routine hypertension care for elderly hypertensive patients.

Evaluation of blood pressure through home monitoring in brazilian primary care: a feasibility study

Blood pressure measurements taken in a clinical setting are subject to errors, therefore there are advantages to monitoring blood pressure at home, especially in in patients diagnosed with hypertension. The study describes the feasibility of home monitoring to assess blood pressure in primary care and compares blood pressure measured at home and during a medical consultation. This cross-sectional study was carried out with patients whose used home blood pressure in the morning and evening, thrice for seven consecutive day sat home. Participants included patients older than 18 years with suspected whitecoat hypertension, taking antihypertensives, or those intolerant of ambulatory blood pressure monitoring, and excluded patients who did not follow the protocol, suffered from an irregular heart rate, and pregnant women. Of the 134 patients who participated in the study, 63.3% had altered blood pressure when measured at health facilities and 48% had higher blood pressure at home. The mean difference between the methods was 10.1 mmHg for systolic and 4.3 mmHg for diastolic. The prevalence of whitecoat hypertension was 19.4%. Blood pressure monitoring at home is a practicable strategy in the Brazilian healthcare system.

Medication adherence and associated factors among elderly hypertension patients with uncontrolled blood pressure in rural area, Northeast Thailand

Purpose

Hypertension is a common disease among elderly. Adherence to antihypertensive medication is a key predictor of optimal blood pressure control that prevents the risk of cardiovascular disease and potentially death. The purpose of this paper is to assess adherence to antihypertension and identify associated factors among the elderly in a rural area, Buengkan province, Thailand.

Design/methodology/approach

A health facilities based cross-sectional study was conducted in Buengkan district. A simple random sampling method was used to select 408 participants. A structured questionnaire adapted from the World Health Organization STEPwise approach was used to collect data. The medication adherence level was identified by pill count with percentage ⩾70 defined as good adherence. Descriptive and summary statistics were used. Bivariate analysis was done using Pearson’s χ2 test, and multivariable analyses were also carried out.

Findings

A total of 408 (143 males and 265 females) elderly hypertension patients with uncontrolled blood pressure participated in this study. Most of the participants were found to have lower adherence to medication treatment (86.8 percent), whereas the remaining ones (13.2 percent) were found to have good adherence. The multivariable logistic regression analysis showed that having a daughter as a care taker (adjust odd ratio=7.99, 95% confidence interval: 1.23–51.778) was significantly associated with high medical adherence.

Originality/value

Hypertension medication adherence among elderly patients with uncontrolled blood pressure was poor. Having a care taker, especially a daughter, is a key to improve adherence. Effective strategy to improve adherence should focus on and involve family participation into the program.
