Application Effect of WeChat Platform Continuity of Care Model Based on KAP Theory on Self-Management of Stroke Patients with Hypertension

Objective: To explore the impact of the WeChat platform continuity of care model based on the KAP (knowledge, attitudes, and practices) theory on the self-management of stroke patients with hypertension after discharge from the hospital. Methods: 62 stroke patients with hypertension discharged from the rehabilitation department of a tertiary A hospital in Nanning City, Guangxi Zhuang Autonomous Region, from October 2022 to April 2023 were sampled by convenience sampling method. Patients discharged from Rehabilitation I were included in the control group, and conventional nursing care was used; while patients discharged from Rehabilitation II were included in the observation group, and WeChat platform continuity of nursing care model based on the KAP theory was implemented. The intervention effect of the two groups was compared. Results: After 4 and 12 weeks of intervention, the diastolic and systolic blood pressure of the patients in the observation group were lower than those in the control group (P < 0.05); after 12 weeks of intervention, the rate of medication adherence and the score of adherence to hypertension treatment in the observation group were significantly higher than those in the control group (P < 0.05). Conclusion: The application of the WeChat platform continuity of care model based on KAP theory to stroke patients with hypertension can improve blood pressure, medication adherence rate, hypertension treatment adherence, and overall enhance the self-management level of these patients.

Objectives: To describe the treatment adherence among hypertensive patients and to determine some related factors to treatment adherence. Research methods: An analytical cross-sectional study was carried out on 360 hypertensive patients being managed and treated at health stations in Hoa Vang district. Result: The overall treatment adherence rate of patients was 16,7%; the highest rate was regular health checkups (84,2%), and the lowest rate was the blood pressure measuring at home (22,5%). The treatment time, education level, support of medical facilities and knowledge are factors related to the hypertension treatment adherence of patients. Conclusion: The hypertension treatment adherence rate of patients was low, 16,7%.

Level of hypertension treatment adherence during pandemic

Adherence to antihypertensive medications is the cornerstone for achieving metabolic syndrome control. The aim of this study was to explore how the pandemic has affected the adherence of patients with high BP to prescribed antihypertensive drugs. This multicentre observational study utilized self-completed questionnaires among patients between June and November 2020. Overall, 842 patients were included in the study. The likelihood of adherence was assessed using the 5‐item version of the Medication Adherence Report Scale (MARS-5Professor Rob Horne). The average MARS score of the sample was 16.81, the median was 4.162, and the most common value was 3 (24.5% of respondents) for the patients treated during the pandemic. The study suggests that several sociodemographic factors but not the COVID pandemic play a role in treatment adherence.

The Relationship Between Self Efficacy and Family Support With Hypertension Treatment Adherence of Elderly

Hypertension is a degenerative disease that increasing in its prevalence. Hypertension requires a long enough time to its treatment, even if there are no symptoms the patients should continue taking medication. So, patients need to obey to take medication. Adherence to taking medication correlated with self-efficacy and family support. This research aims to determine the relationship between self-efficacy and family support in hypertension treatment adherence of the elderly at Widasari Health Center, Indramayu Regency. The research design is a cross-sectional study. The sample of this research was 78 elderly. The data analysis used univariate to explain independent variables such as self-efficacy and family support, the dependent variable is hypertension treatment adherence, while the bivariate was used to determine the relationship between independent variables and the dependent variable. Dependent variable using the chi-square statistical test. The result of this research showed that 61.5% of the elderly had high self-efficacy criteria, 71.8% of the elderly received their family support, and 60.3% of the elderly obey to hypertension treatment adherence. The chi-square statistical test showed that there was a relationship between self-efficacy and family support with hypertension treatment adherence and also there is a relationship between self-efficacy and the level of adherence to taking medication in people with hypertension. It is recommended to increase the elderly self-efficacy by being able to communicate with fellow elderly who are undergoing hypertension treatment and now have reduced symptoms due to treatment adherence. Nurses should be able to provide health promotion about the importance of self-efficacy and family support in increasing compliance for the elderly undergoing hypertension treatment.

PATIENT'S PERSPECTIVES ON TREATMENT ADHERENCE IN HYPERTENSION: RESULTS OF AN ESH SURVEY IN POLAND

Objective: The ESH Working group on Lifestyle, Cardiovascular Therapy and Adherence has developed a web-based questionnaire in different languages to investigate patients’ perspectives on hypertension and treatment adherence. The objective of this survey was to decipher patients’ perception of motivations for and barriers to treatment adherence in hypertension. Design and method: In Poland, a dedicated recruitment strategy has been developed to invite adult patients to complete the survey via targeted information on patient group websites and social media only. In other countries a direct communication from healthcare professional to patient was preferred. Data were collected from May to September 2022. Descriptive statistics were used for analyses. Results: We included 1359 participants (962 men (71%); 67% were hypertensive for >5 years, 88% were treated with antihypertensive medications for at least 3 months). The total median number of tablets taken every day was 4 of which 2 were antihypertensive medications. Antihypertensive medications were prescribed most frequently once (56%) or twice (36%) daily. On a 10-point Likert scale, participants reported a modest impact of hypertension on their quality of life (4), social and family life (2). The median level of stress was 5 out of 10 points. Ninety two of patients performed self-blood pressure measurements at home, most frequently every day (34%) and a few times a week (28%). Self-reported adherence to treatment was perfect in 43% of patients, very high in 30% and intermediate-low in 26% of patients. Main reasons for low adherence to medication included forgetfulness (41%), improvement in well-being (15%), side effects (14%) and running out of medications (11%). The most useful approaches to support adherence reported by participants were cheaper and single-pill combinations as well as leaflets providing better information on treatment. Information provided by physicians on hypertension and its treatment was considered sufficient only for 54% of patients. Conclusions: In a web-based ESH survey in Poland, over 1,300 participants reported a modest impact of hypertension on their quality of life and a moderate level of anxiety, usually non-intentional non-adherence to prescribed antihypertensive medications, and the necessity to improve the information provided to them.

Determinants of Hypertension Treatment Adherence during the COVID-19 Pandemic: Lesson Learned from Various Studies Sites in Indonesia

Background: Hypertension is the most common comorbid disease which can cause further complications in COVID-19 patients. On the contrary, the pandemic has also caused lower health services and adherence to hypertension therapy. This study aimed to examine the impact of the COVID-19 pandemic on medication adherence in people with hypertension in Indonesia.Methods: The research was conducted using an analytical quantitative method. Patients with hypertension from seven islands across Indonesia were recruited based on eligibility criteria during Bulan Bakti 2021, a social outreach by Ikatan Senat Mahasiswa Kedokteran Indonesia about basic health across Indonesia. The demographic and medication history of the respondents were recorded. The Indonesian version of the Morisky Medication Adherence Scale (MMAS-8) questionnaire was distributed, and the medication adherence level was assessed.Results: A total of 1155 patients, mainly females (62.2%) participated in this study. More than half of the patients had low adherence (55.25%). Males (Adjusted Odd Ratio (AOR) 0.777 [CI 95% 0.529–1.019]), employed (AOR 0.857 [CI 95% 0.495–1.483]), higher income (AOR 0.522 [CI 95% 0.393–0.713]), and those who had information from healthcare worker (AOR 0.583 [CI 95% 0.361–0.878]) were found to have better medication adherence in multivariate logistic regression test.Conclusion: Medication adherence level in patients with hypertension during the pandemic is markedly low. Integrated preventive and promotive measures, especially from healthcare workers, are needed to prevent further morbidity and mortality.

Prevalance of hypertension treatment adherence at E hospital

Objectives: Describe the current situation and some associated factors to the adherence to blood pressure treatment of hypertensive patients at hospital E.
 Methods: This is a cross-sectional study conducted from March 2022 to July 2022. The study involved 101 patients.[1]
 Results: Out of 101 study participants. The mean adherence score to antihypertensive treatment was 49.3 (4.13) points. Most patients do not make the decision to stop taking their blood pressure medication, do not take their medication carelessly, and do not take other people's medications. Patients regularly make follow-up appointments with medical staff. We did not find any associated factors affecting the practice of controlling hypertension in the patients participating in the study. Patients who used more than 1 drug had higher blood pressure goals than patients who used only 1 drug.
 Conclusion: Our study provides information on the adherence to treatment for hypertension in the group of patients at the hospital

General self-efficacy and hypertension treatment adherence in Algerian private clinical settings.

BackgroundThe purpose of this study was to investigate the connection between self-efficacy and treatment adherence, working on the assumption that self-efficacy plays a role in determining treatment adherence in chronic diseases. Hypertension affects one-third of the world’s population. In Africa, hypertension is a leading cause of death from a non-communicable disease. Modifications to lifestyle and behavior, as well as increased access to pharmaceuticals, are necessary for every African nation to bring the prevalence of hypertension and cardiovascular disorders under control.MethodsIn order to assess the predictive association between the two, we conducted research on 216 hypertensive patients who were treated in private clinics in Algeria. These patients were given two assessments to fill out: one was called the general self-efficacy scale (GSES), and the other was called the treatment adherence scale. Comparisons of male and female self-efficacy and adherence were made with the help of Pearson’s correlation coefficient and a sample independent t-test (selfefficacy, adherence to treatment).ConclusionsSelf-efficacy in general has been shown to be connected with adherence to hypertension therapy (r(214) = 0.496, p=0.01, <0.05). There is no significant difference between the sexes in either selfefficacy (t(214)=0.985, p=0.326, >0.05) or hypertension treatment adherence (t(214)=0.034, p=0.973, >0.05). A higher level of self-efficacy was found to have a positive correlation with a higher level of treatment adherence; it is possible to increase the medication adherence of hypertension patients by enhancing their level of self-efficacy. It is important for those working in health care to acknowledge the significance that self-care plays in overall health.

The effect of self-management support on knowledge level, treatment compliance and self-care management in patients with hypertension

Objective: This study was carried out to determine the effect of self-management support given to patients diagnosed with hypertension on the hypertension knowledge level, treatment adherence and self-care management, and to examine the changes in patients' blood pressure after the self-management support. Background: The rise of chronic diseases such as hypertension necessitates the equipment of patients with sufficient knowledge and skills necessary to manage their disease and self-care. Methods: This randomised controlled research was conducted with a total of 137 patients, including 69 intervention and 68 control patients. Data were collected using the “Patient Information Form”,

Relationship of Patient Satisfaction With Hypertension Treatment Adherence

Adherence in general is the level of a person's behavior in getting treatment, following a diet, and implementing lifestyle changes in accordance with the recommendations of health care providers with patients. Satisfaction is a person's feeling of pleasure that comes from the comparison between the pleasure of an activity and a product with his expectations. This research is descriptive correlation with cross-sectional approach. The population in this study were hypertensive patients undergoing treatment at the internal medicine polyclinic of Cut Meutia RSU, North Aceh Regency, amounting to 944 people, while the sample was 90 people. Data were collected through interviews using a questionnaire. The data were analyzed by Chie-square test using a computerized program. The results showed that of the 90 respondents, in the satisfied category, 43 people (89.6%) adhered to hypertension treatment and 5 people (10.4%) did not. And in the dissatisfied category there are 7 people (16.7%) obedient to hypertension treatment while 35 people (83.3%) are not. After statistical testing with the Chie-square test was carried out, the results were p = 0.000 (p &lt;0.05), this means that there is a significant relationship between satisfaction and compliance with hypertension patients in undergoing treatment at BLU Cut Meutia RSU, North Aceh Regency in 2017. So it can be concluded that patient satisfaction is very necessary to achieve medication adherence. It is recommended that it can be used as a health education material and presumably can be a reference for further researchers on patient satisfaction with hypertension medication adherence.

Factors influencing treatment adherence in hypertension and HIV management in South Africa: A comparative literature review.

Hypertension (HTN) is the most significant risk factor for cardiovascular disease (CVD) in South Africa (SA), with one in three people over the age of 25 suffering from HTN. Whilst human immunodeficiency virus and acquired immunodeficiency syndrome (HIV/AIDS) are the leading causes of death in South Africa, CVD is in the top 10 causes of death, demonstrating the importance of detecting and controlling blood pressure early on. This study aimed to review adherence factors to antihypertensive medication and antiretroviral therapy (ART) and evaluate the resulting factors influencing adherence discrepancies within the South African population. A comprehensive literature review was carried out. PubMed, ScienceDirect, Cochrane and Embase were searched for English publications between 2000 and 2021. A total of 50 articles covering quantitative and qualitative studies were included. Many studies identified poor adherence levels to antihypertensive treatment, reaching a substandard adherence rate of 41.9%, whilst most studies on the HIV-positive population reported good levels of adherence, with adherence rates of more than 90%. Being of the male gender, advanced age, low socioeconomic status and a low level of education were associated with unsatisfactory adherence rates in both groups. Within the HIV group, more participants had better knowledge concerning the extent of their disease and its required treatments. The results present substandard adherence levels to antihypertensives compared with antiretroviral (ARV) adherence, despite the influence of more non-adherence factors in the HIV group. The authors recommend better adherence counselling for patients with HTN during every clinic visit, regular healthcare worker training and the implementation of ART adherence programmes in patients with hypertension.

Factors associated to treatment adherence in elderly people with hypertension: A cross-sectional study in Ho Chi Minh city

BackgroundTreatment of hypertension should be continuous, and patients should be closely monitored for treatment adherence. However, non-compliance still exists globally. This study aimed to determine treatment adherence among patients aged ≥60 years with hypertension and its associated factors in an urban district of Ho Chi Minh City, Vietnam. MethodsA cross-sectional study evaluated treatment adherence in two areas: medication and non-pharmacological adherence. Medication adherence was measured using the 8-item Morisky Medication Adherence Scale. Non-pharmacological adherence was based on the Ministry of Health guidelines for hypertension treatment and assessed by lifestyle changes, including smoking cessation, alcohol consumption restriction, reduced salt intake, increased physical activity, and regular follow-up visits. ResultsA total of 537 people participated in the study, of whom females accounted for the majority (63.7%), and patients aged 60–70 years old accounted for 50%. The proportion of patients with medication adherence was 11.7%. The percentages of patients who adhered to non-smoking and limited alcohol intake were 93.5% and 92.9%, respectively. A total of 76.9% of patients underwent regular check-ups. The proportion of patients who adhered to moderate and high levels of physical activity was 64.3%. Patients who were compliant with salt intake reduction accounted for 63.1%. Factors related to antihypertensive drug adherence included disease duration and chronic comorbidities. Factors associated with non-drug adherence included health insurance, comorbidities, and nutritional status. ConclusionsIntervention programs to increase hypertension treatment adherence among elderly patients should focus on educating drug adherence and salt reduction, especially in long-standing and comorbidities patients.

PATIENT PERSPECTIVES ON TREATMENT ADHERENCE IN HYPERTENSION: PRELIMINARY RESULTS OF AN ESH SURVEY IN FIVE COUNTRIES

Objective: The ESH Working group on Lifestyle, Cardiovascular Therapy and Adherence, in partnership with Servier, has developed a web-based questionnaire in different languages to investigate patients’ perspectives on hypertension and treatment adherence. The objective of this survey was to decipher patients’ perception, motivations and barriers to drug treatment adherence in hypertension. Design and method: Eligible participants were men and women aged &gt; 18 years, living in France, Germany, Italy, Spain and UK, with a diagnosis of hypertension made by a physician and internet access. Data were collected through patients’ websites and organizations from January to March 2022. Results: We included 595 participants (329 women, 55.3%, mean age 65 y); 72% were hypertensive for &gt; 5 years, 93% were treated with antihypertensive medications for &gt; 3 months and 50% had uncontrolled (140/90 mmHg) office BP at 3 months. The median number of all medications taken every day was 4 of which 2 were antihypertensive drugs. On a 10-point Likert scale, participants reported a modest impact of hypertension on their quality of life (3) or social and family life (3.1). The median level of stress was 5.2. In 76.6% of participants home BP was measured several times weekly (25%) or monthly (31%) or more. Antihypertensive medications were stopped unintentionally by 40% or taken irregularly by 44% of patients. The reasons for non-adherence to medications were forgetfulness (45%), side effects (17%) and running out of medications (15%). In 50% of cases, patients do not inform their physicians when stopping medications. The most useful approaches to support adherence reported by participants were single-pill combinations and smaller and cheaper pills. Information on hypertension and its treatment were considered sufficient for 33% of patients. Conclusions: In patients with internet access and willing to participate, our survey shows that despite having an uncontrolled office 3 month BP in 50% of them, participants report: 1) a modest impact of hypertension on their quality of life and a moderate level of anxiety, 2) frequent and usually non intentional non-adherence to prescribed antihypertensive medications, and 3) the necessity to improve the information provided to them.

Abstract 9038: Success of Online CME at Improving Competence and Confidence Related to Treatment Adherence in Pulmonary Arterial Hypertension

Introduction: Despite treatment advances in PAH, many patients have difficulty adhering to therapy, resulting in decreased persistence and poor outcomes. We sought to determine if online continuing medical education (CME) could improve the competence and confidence of cardiologists related to strategies to improve treatment adherence in PAH. Methods: This CME intervention comprised of a 15-minute online video-based rapid-fire discussion between 2 expert faculty. A repeated pairs pre-/post-assessment study design was used and McNemar’s test assessed significance (P &lt;.05 is considered significant), with Cohen’s d being used to assess educational impact (.20-.49 a small effect, .50-.79 a moderate effect, and &gt; .80 a large effect). The activity launched October 1, 2020 and data were collected through January 11, 2021. Results: In total, 180 cardiologists were included in the analysis. Overall, there were competence and confidence improvements seen among participants from pre- to post-assessment: • 13% of cardiologists (P&lt;.01) improved at selecting the most appropriate PAH therapy for better adherence for a patient who requires treatment escalation due to intermediate-risk status yet struggles to follow a rigid medication schedule • 27% of cardiologists (P&lt;.001) improved at selecting the most appropriate strategy to manage PAH treatment-related side effects • 36% of cardiologists had a measurable increase in confidence in ability to manage side effects during uptitration of PAH specific therapiesContinued educational gaps:• 61% of cardiologists failed to choose appropriate therapy to improve adherence for an intermediate-risk patient who struggles to follow a rigid medication schedule • 50% of cardiologists failed to select the most appropriate strategy to manage PAH treatment-related side effects Conclusions: This study demonstrates the success of online CME on improving competence and confidence of pulmonologists related to treatment adherence in PAH. Continued gaps were identified for future educational targets.

The Effect of Social Support on Treatment Adherence in Hypertension in China.

ObjectiveTreatment nonadherence is a major problem in the management of hypertension. There are many factors influencing the treatment adherence of hypertensive patients. The aim of this study was to examine the effect of social support on the treatment adherence in hypertension in China.Patients and MethodsA total of 453 patients with hypertension hospitalized in a tertiary hospital in Xi’an, China were invited to participate in this cross-sectional study. Data were collected by “modified Chinese Hill-Bone compliance to high blood pressure therapy scale” and “Chinese Family Support Scale”.ResultsIt was found that 31.1% of patients were adherent with their antihypertensive treatments. Gender, duration of antihypertensive drug used, number of antihypertensive drugs used and social support were independently associated with hypertensive treatment adherence. Social support was strongly and positively associated with the hypertensive treatment adherence (P<0.001, OR = 0.752, 95% CI: 0.678–0.833). Family social support was provided to hypertensive patients mainly through their nuclear family, that is spouses, partner or children. Treatment adherence of hypertensive patients was positively correlated to the three subgroups of social support. It was found that social support provided to patients from social resource (r=0.568) had greater impact on treatment adherence than that from kinship (r=0.364) and nuclear family (r=0.262).ConclusionTreatment adherence of patients with hypertension was found to increase positively as their social support increased. In addition to the support given to patients from nuclear family members, other social support especially professional agencies and community organizations should also be promoted and strengthened.

Cost-Effectiveness of Improved Hypertension Management in India through Increased Treatment Coverage and Adherence: A Mathematical Modeling Study.

Background:Despite the availability of effective and affordable treatments, only 14% of hypertensive Indians have controlled blood pressure. Increased hypertension treatment coverage (the proportion of individuals initiated on treatment) and adherence (proportion of patients taking medicines as recommended) promise population health gains. However, governments and other payers will not invest in a large-scale hypertension control program unless it is both affordable and effective.Objective:To investigate if a national hypertension control intervention implemented across the private and public sector facilities in India could save overall costs of CVD prevention and treatment.Methods:We developed a discrete-time microsimulation model to assess the cost-effectiveness of population-level hypertension control intervention in India for combinations of treatment coverage and adherence targets. Input clinical parameters specific to India were obtained from large-scale surveys such as the Global Burden of Disease as well as local clinical trials. Input hypertensive medication cost parameters were based on government contracts. The model projected antihypertensive treatment costs, avoided CVD care costs, changes in disability-adjusted life year (DALYs) and incremental cost per DALY averted (represented as incremental cost-effectiveness ratio or ICER) over 20 years.Results:Over 20 years, at 70% coverage and adherence, the hypertension control intervention would avert 1.68% DALYs and be cost-saving overall. Increasing adherence (while keeping coverage constant) resulted in greater improvement in cost savings compared to increasing coverage (while keeping adherence constant). Results were most sensitive to the cost of antihypertensive medication, but the intervention remained highly cost-effective under all one-way sensitivity analyses.Conclusion:A national hypertension control intervention in India would most likely be budget neutral or cost-saving if the intervention can achieve and maintain high levels of both treatment coverage and adherence.

The Relationship of Family Support and Patients Knowledge with The Treatment Adherence of Hypertension Patients

Hypertension is one of the diseases that cause morbidity and mortality rates in Indonesia. The treatment adherence level in developing countries is only 50%. The purpose of this study was to analyze the relationship between family support and patients’ knowledge with treatment compliance for hypertension patients. The design of this study used a correlational description approach with a cross-sectional approach. The instrument used was a questionnaire. The population of this study was 189 elderly hypertension patients. The samples are 51 people using a consecutive sampling technique. The independent variables of this study were family support and patients’ knowledge regarding the treatment of hypertension. The dependent variable of this study was hypertension treatment adherence. The data were analyzed using chi-square with α≤0.05. Statistical test results show a correlation with compliance with hypertension treatment showed that there was a strong relationship between family support with hypertension treatment adherence with p = 0.001, and there was no relationship between patients’ knowledge with adherence to hypertension treatment with p=0.772. This study concludes that there is a relationship between family support and the treatment adherence of elderly hypertension patients. The treatment adherence rate of elderly patients with hypertension is still weak.

Validity and reliability of a short self-efficacy instrument for hypertension treatment adherence among adults with uncontrolled hypertension

ObjectiveTo establish the reliability and validity of a self-report measure designed to assess self-efficacy for hypertension treatment adherence. MethodsThis investigation was embedded within a six-month randomized clinical trial (RCT), which demonstrated that a tailored, stage-matched intervention was more effective at improving hypertension control than usual care among individuals (n = 533) with repeated uncontrolled hypertension. The instrument used to assess self-efficacy for hypertension treatment adherence (SE-HTA) comprised three subscales that assessed diet self-efficacy (DSE), exercise self-efficacy (ESE), and medication self-efficacy (MSE). To determine SE-HTA validity and reliability, we assessed internal consistency using Cronbach’s α coefficients, conducted exploratory factor analysis, and evaluated convergent and discriminant validity, as well as test-retest reliability using Spearman’s ρ correlation coefficients. ResultsCronbach’s α (internal consistency) values for DSE, ESE, and MSE were 0.81, 0.82 and 0.74. Factor analysis and the scree plot demonstrated three distinct factors, which correspond to the three subscales contained in the SE-HTA instrument. SE-HTA possessed good convergent and discriminant validity, and moderate test-retest reliability. ConclusionThe SE-HTA instrument containing diet, exercise, and medication adherence subscales is valid and reliable in adults with uncontrolled hypertension. Practice implicationsThis SE-HTA instrument measures self-efficacy and could help facilitate behavior change in hypertension.

Impact of patient knowledge on hypertension treatment adherence and efficacy: A single-centre study in Poland.

Introduction: Recent studies show that treatment of arterial hypertension is unsuccessful. This is due to the patients' insufficient knowledge of about the therapeutic methods and the consequences of not treating arterial hypertension.Objectives: The aim of the study was to evaluate the patients' knowledge concerning therapeutic options, prophylaxis, and complications of arterial hypertension. The study also assessed the effect of such knowledge on hypertension treatment adherence and efficacy.Patients and Methods: The survey included 488 patients (250 female and 238 male), aged over 18 years, diagnosed with and treated in outpatient and inpatient settings at selected healthcare institutions in Poland. A custom-made questionnaire, based on references on this subject, was the key tool in the present study. Information about the course of the disease and evaluation of hypertension treatment efficacy was based on the patients' medical records.Results: The study found that 54.7% of the subjects had good knowledge about arterial hypertension, 40.0% had average knowledge, and 5.3% had poor knowledge. The extent of knowledge about the disease was significantly dependent on the level of education and the place of receiving medical care (p< 0.05). Good knowledge was significantly associated with controlled blood pressure, number of antihypertensive drugs used, frequency of hospitalization, as well as with medication adherence, and healthy lifestyle behaviours (p< 0.05).Conclusions: More than half of the patients presented good knowledge but a large group still had poor knowledge, especially patients with a low level of education and with hypertension treated at a general practitioner's clinic. The results of our study clearly show that knowledge about arterial hypertension affects medication adherence and healthy lifestyle behaviours and improves hypertension treatment efficacy.
