Adherence to hypertension medication: Quantitative and qualitative investigations in a rural Northern Vietnamese community.

ABSTRACT:

Objectives

The purposes of this study were to assess the adherence to medication of hypertensive patients visiting community health stations in a rural area in Vietnam, to examine the relationship between levels of adherence and cardiovascular risk among hypertensive patients and to further understand factors influencing adherence.

Methods

This study is part of a prospective one-year study conducted on hypertension management in a population aged 35 to 64 years. Data on age, sex, blood pressure and blood test results were collected at baseline. Cardiovascular risk was based on the Cardiovascular Risk Prediction Model for populations in Asia. To calculate medication adherence, the number of days the drug was taken was divided by the number of days since the first day of the prescription. A threshold of 80% was applied to differentiate between adherence and non-adherence. In-depth interviews were conducted among 18 subjects, including subjects classified as adherent and as non-adherent.

Results

Among 315 patients analyzed, 49.8% of the patients were adherent. Qualitative investigation revealed discrepancies in classification of adherence and non-adherence based on quantitative analysis and interviews. No significant difference in medication compliance between two cardiovascular disease risk groups (<10% vs. >10% risk) was found, also not after controlling for age, sex, and ethnicity (adjusted odds ratio at 1.068; 95% CI: 0.614 to 1.857). The odds of medication adherence in females was 1.531 times higher than in males but the difference was not statistically significant (95% CI: 0.957 to 2.448). Each one-year increase in age resulted in patients being 1.036 times more likely to be compliant (95% CI: 1.002 to 1.072). Awareness of complications related to hypertension was given as the main reason for adherence to therapy.

Conclusions

Medication adherence rate was relatively low among hypertensive subjects. The data suggest that rather than risk profile, the factor of age should be considered for guiding the choice on who to target for improving medication adherence.

Project description:ObjectiveAdherence to hypertension treatment is a major public health challenge for low and middle-income countries particularly in sub-Saharan Africa. One potential reason could be the discordance between lay and medical explanatory models of hypertension and its treatment. Understanding community perceptions and practices may contribute to improving hypertension control as they present insights into psychosocial and cultural factors that shape individual behaviour. We explore community perceptions regarding hypertension and its treatment in rural northern Ghana and how they differ from medical understanding.DesignThis was a qualitative study using semi-structured interviews and focus group discussions to collect data, which were analysed using a thematic approach.SettingA multisite study conducted in four rural communities in two regions of northern Ghana.ParticipantsWe conducted 16 semi-structured interviews and eight focus group discussions with community leaders and members, respectively.ResultsThree major themes were identified: community perceptions, treatment options and community support for people with hypertension. Community perceptions about hypertension include hypertension perceived as excess blood in the body and associated with spiritual or witchcraft attacks. Traditional medicine is perceived to cure hypertension completely with concurrent use of biomedical and traditional medicines encouraged in rural communities. Community members did not consider themselves at risk of developing hypertension and reported having inadequate information on how to provide social support for hypertensive community members, which they attributed to low literacy and poverty.ConclusionThere is a substantial mismatch between communities' perceptions and medical understanding of hypertension and its treatment. These perceptions partly result from structural factors and social norms shaped by collective processes and traditions that shape lay beliefs and influence individual health behaviour. Socioeconomic factors also thwart access to information and contribute to inadequate social support for persons with hypertension. These findings highlight the need for a public health approach to hypertension control targeting families and communities.

Project description:Background: Few studies have investigated the association between medication literacy and medication adherence as well as the influence of medication literacy on medication adherence in hypertensive patients. Thus, the goal of the present study was to determine the association between medication literacy and medication adherence in hypertensive patients. Methods: A cross-sectional survey was conducted between August 2016 and December 2016. Self-administered questionnaires were completed, including a self-developed and structured socio-demographic questionnaire; a self-developed, validated, and self-reported Medication Literacy Scale for Hypertensive Patients (C-MLSHP) used for medication literacy measurement; and the Chinese Version of the Morisky Medication Adherence Scale-8 (C-MMAS-8), an eight-item validated, self-report scale for adherence measurement with a total score range of 0-8. A cut-off of 6 was applied to differentiate adherence levels, including patients with an MMAS score <6 (low adherence), MMAS score = 8 (high adherence), and MMAS score ?6 and <8 (moderate adherence). In this study, hypertensive patients' medication literacy levels and adherence to antihypertensive agents were identified. Pearson correlation analysis was carried out to identify the correlation between medication literacy and adherence. Binary logistic regression analysis was performed with medication adherence as the outcome variable in order to confirm factors associated with medication adherence. Results: A total of 420 hypertensive patients, including 198 women and 222 men with a mean age of 60.6 years (SD = 12.4), were recruited. The mean score of hypertensive patients on the medication literacy scale was 24.03 (SD = 5.13). The mean scores of the four dimensions of knowledge, attitude, skill, and behavior on the medication literacy scale of this study were 6.22 ± 2.22, 5.04 ± 1.16, 4.50 ± 2.21, and 8.27 ± 1.90, respectively. Regarding medication adherence, the mean score of the C-MMAS-8 in this study was 4.82 (SD = 2.11). A total of 63.6% of patients presented with low adherence, 29.5% presented with moderate adherence, and 7.6% presented with high adherence. The Pearson correlation results showed that medication literacy (r = 0.342, P < 0.01) as a whole variable and the three dimensions of knowledge (r = 0.284, P < 0.01), attitude (r = 0.405, P < 0.01), and behavior (r = 0.237, P < 0.01) were significantly associated with medication adherence. Binary logistic regression analysis indicated that annual income [OR 1.199 (95% CI: 1.011-1.421); P = 0.037] and two dimensions of attitude [OR 2.174 (95% CI: 1.748-2.706); P = 0.000] and behavior [OR 1.139 (95% CI: 1.002-1.294); P = 0.046] in medication literacy were found to be independent predictors of medication adherence. Individuals with better attitudes and behavior literacy in medication literacy were more likely to adhere to the use of antihypertensive agents. Those who had higher annual incomes were more likely to adhere to the use of antihypertensive agents. Conclusion: The levels of medication literacy and medication adherence of hypertensive patients are suboptimal and need to be improved in China. The level of medication literacy in patients with hypertension could affect their adherence to antihypertensive drugs. It was suggested that hypertensive patients' medication adherence could be improved and driven by increasing the medication literacy level, especially in the attitude and behavior domains. Pertinent strategies that are specific to several dimensions of medication literacy should be developed and implemented in order to promote full medication literacy among hypertensive patients, thus facilitating optimal adherence and blood pressure control.

Project description:BackgroundWorldwide, hypertension control rates remain suboptimal despite clinically effective antihypertensive drug therapy. Patient failure to take medication as prescribed (ie, nonadherence) is the most important factor contributing to poor control. Smartphone apps can facilitate the delivery of evidence-based behavior change techniques to improve adherence and may provide a scalable, usable, and feasible method to deliver self-management support.ObjectiveThe aim of this study is to explore patients' experiences of the usability and feasibility of smartphone apps to support self-management and improve medication adherence in hypertension.MethodsA qualitative descriptive study was conducted. A total of 11 people living with hypertension from the West of Ireland were sampled purposively and interviewed about their experience of using a self-management app for a 4-week period, which included two key functionalities: self-monitoring of blood pressure (BP) and medication reminders. Thematic analysis was carried out on the semistructured interview data.ResultsParticipants' age ranged from 43 to 74 years (mean 62 years, SD 9.13). Three themes were identified: digital empowerment of self-management, human versus digital systems, and digital sustainability. Although patients' experience of using the technology to self-monitor BP was one of empowerment, characterized by an enhanced insight and understanding into their condition, control, and personal responsibility, the reminder function was only feasible for patients who reported unintentional nonadherence to treatment. Patients experienced the app as a sustainable tool to support self-management and found it easy to use, including those with limited technological competence.ConclusionsThe study's findings provide new insights into the experience of using apps to support medication adherence in hypertension. Overall, the data support apps as a usable and feasible method to aid self-management of hypertension and highlight the need for personalized functionality, particularly with regard to medication adherence reminder strategies. The study's findings challenge the perspective that the use of these technologies to support self-management can inevitably add to the burden of treatment experienced by patients.

Project description:BackgroundThe shortage of formal health workers has led to the utilization of Community-Based Health Volunteers (CBHV) to provide health care services to people especially in rural and neglected communities. Community-based health volunteers have been effective partners in health care delivery at the community level for many years. The challenge is how to retain these volunteers and also sustain their activities. This study explored factors affecting retention and sustainability of community-based health volunteers' activities in a rural setting in Northern Ghana.MethodsThis was a qualitative study comprising thirty-two in-depth interviews (IDIs) with health volunteers and health workers in-charge of health volunteers' activities. Purposive sampling technique was used to select study participants for the interviews. The interviews were transcribed and coded into themes using Nvivo 10 software. The thematic analysis framework was used to analyze the data.ResultsStudy participants reported that the desire to help community members, prestige and recognition as doctors in community mainly motivated them to work as health volunteers. Lack of incentives and logistical supplies such as raincoats, torch lights, wellington boots and transportation in the form of bicycles to facilitate the movement of health volunteers affected the work. They suggested that lack of these things discouraged them from working as health volunteers. Most of the dropout volunteers said lack of support and respect from community members made them to stop working as health volunteers. They recommended that community support, incentives and logistical supplies such as raincoats, torch light, wellington boots, bicycles, awards to hard working volunteers are mechanisms that can help retain community-based health volunteers and also sustain their activities.ConclusionProviding means of transport and non-monetary incentives would help to retain community-based health volunteers and also sustain their activities at the community level.

Project description:BACKGROUND:An interprofessional medication adherence program (IMAP) for chronic patients was developed and successfully implemented in the community pharmacy of the Department of ambulatory care and community medicine (Lausanne, Switzerland). This study assesses the capacity of a physician and a nurse at the infectious diseases service of a public hospital and of community pharmacists in the Neuchâtel area (Switzerland) to implement the IMAP in their practice. METHODS:Mixed method, prospective, observational study. Quantitative and qualitative analyses of the implementation process were conducted following the RE-AIM model (reach, effectiveness, adoption, implementation and maintenance). RESULTS:Implementation started in November 2014. One physician, one nurse, and five pharmacists agreed to participate. Healthcare professionals perceived the benefits of the program and were motivated to implement it in their practice (adoption). Seventeen patients were included in the program; 13 refused to participate. The inclusion of naïve HIV patients was easier than the inclusion of experienced patients with difficult psychosocial issues (reach). Pharmacists were engaged in reinforcing patient medication adherence in 25% of interviews (effectiveness). Key facilitators expressed by healthcare professionals were patient inclusion by the physician and the nurse instead of the pharmacist and the organisation of regular meetings between all stakeholders. In contrast, the encountered barriers were the lack of time and resources, the lack of team uptake, and the lack of adoption by senior managers (implementation). Interviewed patients were all satisfied with this new program, encouraging healthcare professionals to scale it up. Structural changes allowed the hospital and one pharmacy to enter the maintenance stage (maintenance). CONCLUSION:The research team and collaboration between all professionals involved played an important role in this implementation. However, the dissemination of such a program to a larger scale and for the long term requires financial and structural resources as well as transitional external support.

Project description:BackgroundDietary related misconceptions during pregnancy affect the heath of mothers and their growing babies. Misconceptions vary from place to place and from community to community. Understanding of a given community's food perceptions during pregnancy helps policy makers able to design cultural appropriate interventions. In Ethiopia, however, evidences on food beliefs and perceptions during pregnancy are limited. Therefore, this study is aimed at qualitatively assessing community food beliefs during pregnancy in rural kebeles of Ofla Woreda, Northern Ethiopia.MethodsWe conducted 10 in-depth interviews (n = 10) and four focus group discussions (n = 32) among purposively selected community groups including pregnant mothers, religious leaders, and elders in rural kebeles of Ofla Woreda, Northern Ethiopia. Data were transcribed word-for-word, translated into English, and uploaded into ATLAST ti version 7.5.1.6. Data were analyzed following the principles of thematic analysis. Line-by-line coding was applied to identify codes; identified codes were categorized based on their similarities and differences and themes were developed inductively.ResultsThree main themes were identified inductively; foods positively and negatively linked with pregnancy; perceived benefits and harms of alcoholic drinks during pregnancy; and religion and fasting. In this study, consumptions of animal source foods such as egg were discouraged because such foods were perceived to increase the risk of having big baby that could delay delivery. However, intakes of locally produced alcoholic drinks during pregnancy were encouraged by the local community. Furthermore, avoidance of animal source foods and meal skipping during religious fasting-periods were also common practices among pregnant mothers in the study area.ConclusionsThis study explored misconceptions on food intakes during pregnancy. Positive attitude towards intake of "soft" alcoholic drinks might result in alcohol related teratogenic effects. Restriction on the intakes of nutrient rich diets due to religious fasting and other misconceptions would lead to insufficient nutrient intake both to the mothers and their growing fetus. Culturally appropriate intervention to improve awareness on healthy dietary intake during pregnancy is needed.
