Hypertensive patients' knowledge of high blood pressure

Persons' experiences of having hypertension: An interview study

Background

among the 1-1.5 billion persons with hypertension globally only, 20-30% have controlled blood pressure (BP). The most important problem identified is non-adherence to treatment, i.e., failure to change lifestyle and to take prescribed medication. Knowledge about the reasons for this is limited.

Objectives

The aim of the study was to explore people's experiences of having hypertension.

Design

Inductive design based on qualitative interviews.

Settings

The south of Sweden.

Participants

Twelve adults diagnosed with hypertension and treated in primary care were interviewed.

Methods

The transcribed interviews were analysed using content analysis, which rendered three categories.

Results

The individuals adapted to their diagnosis in different ways. Collaboration with the staff gave security, but the persons still perceived anxiety and uncertainty.

Conclusions

To meet the needs of people with hypertension, strategies such as person-centred counselling and care, using digital interventions, following national guidelines and starting nurse-led clinics, may be of help. These strategies can give a foundation for increased self-efficacy, which is crucial for persons to be able to change lifestyle and adhere to prescribed medication in order to achieve BP control.

Health literacy in persons at risk of and patients with coronary heart disease: A systematic review

BACKGROUND

Health literacy (HL) plays a crucial role in the maintenance and improvement of individual health. Empirical findings highlight the relation between a person's HL-level and clinical outcomes. However, the role of HL in persons at risk for coronary heart disease (CHD) and patients with CHD has not been researched conclusively.

OBJECTIVE

The aim of this study was to review systematically the current evidence on HL, its dimensions (access to, understanding, appraisal and apply of health-related information), and its important influencing factors, with regard to CHD risk.

METHOD

We used a mixed-methods approach. Eligible articles needed to employ a validated tool for HL or mention the concept and at least one of its dimensions. After the screening process, 14 quantitative and 27 qualitative studies were included and referred to one or more dimensions of HL. Six observational studies measured HL with a validated tool.

RESULTS

Findings suggest that patients with lower HL feel less capable to perform lifestyle changes, exhibit fewer proactive coping behaviors, are more likely to deny CHD, are generally older, are less often employed, have lower educational levels and lower socioeconomic status, experience faster physical decline, and use the healthcare system less, compared to patients with higher HL. Barriers to HL include inadequate provision of information by health providers, lack of awareness of the risk factors for CHD, perceived impairment of quality of life due to lifestyle changes, and negative experiences with the healthcare system. Facilitators include a good patient-physician relationship based on good communicative competences of health providers.

CONCLUSIONS

The concept of HL yields a promising potential to understand the process from obtaining information to actual health behavior change, and the results clearly indicate the need for more systematic research on HL in CHD patients and persons at risk.

It's all a matter of necessity and concern: A structural equation model of adherence to antihypertensive medication

OBJECTIVE

Hypertension is often treated pharmacologically, yet adherence is poor. Beliefs about antihypertensive medicine, i.e., the necessity-concern framework (NCF), are valuable for explaining adherence. Therefore, a model structure is transferred from hypercholesterolemia to hypertension, assuming a mediating role of the NCF.

METHODS

Patients with hypertension (n=273) were surveyed online about demographics, health- and treatment-related factors, control beliefs, necessity and concern beliefs about their medication, and adherence. The data were analyzed using structural equation modeling (SEM).

RESULTS

Necessity was positively (β=0.26, p=0.009) and concern was negatively (β=-0.51, p=0.020) associated with adherence. The NCF mediated the influence of background variables on adherence. Necessity was associated with comorbidity (β=-0.36, p<0.001), treatment time (β=0.19, p=0.004), emotionally supportive doctor-patient communication (β=0.12, p=0.045), side effects (β=0.16, p=0.013), personal control (β=-0.13, p=0.022), and treatment control (β=0.29, p<0.001). Concern was associated with side effects (β=0.38, p<0.001) and beliefs about medicine in general being harmful (β=0.61, p<0.001). The model fit was acceptable (RMSEA=0.61).

CONCLUSION

The transferred adherence model with the necessity-concern framework as a mediating factor was confirmed in hypertension, explaining more variance than previous approaches (23%).

PRACTICE IMPLICATIONS

A personalized, emotionally supportive doctor-patient communication could be key to addressing beliefs about medicine and therefore to increasing adherence.

A Study on Knowledge, Awareness, and Medication Adherence in Patients with Hypertension from a Tertiary Care Centre from Northern Sri Lanka

Objective

To assess the patient's knowledge and awareness about hypertension and adherence to antihypertensive medication among hypertensive patients with validated Morisky questionnaires in a tertiary care centre of northern Sri Lanka.

Methods

A cross-sectional descriptive comparative study was carried out at Teaching Hospital Jaffna, from January 2017 to April 2017. Hypertensive patients were recruited by systematic randomized controlled sampling and interviewed with validated Morisky questionnaires to assess their knowledge about hypertension. Data were analyzed using SPSS (version 21) analytical package.

Results

73 of 303 patients were males. 69.9% of patients had adequate knowledge about hypertension. 40.5% of patients were unaware of their disease status. 75.8% of patients could not recall their blood pressure values at the time of diagnosis. 72.3% of patients were unaware of their values of blood pressure during their last outpatient clinic visit. 48.2% of patients had awareness of target organ damage due to hypertension (kidney, 72, 23.7%; heart, 128, 42.2%; brain, 140, 46.7%; eye, 42, 13.8%). Most of the patients had poor drug compliance. The most common reasons for nonadherence were forgetfulness (70, 23.1%) and interruptions of daily routine (53, 17.5%).

Conclusion

The knowledge about hypertension among majority of patients was reasonable. But they were unaware of their disease status. The drug compliance among them was poor. Forgetfulness and interruptions of daily routine were common reasons attributed for nonadherence.

Perspectives on Hypertension in the New England Cape Verdean Community

This study characterizes patient understanding of hypertension and its management in a Cape Verdean immigrant community. We conducted 20 semi-structured interviews with Cape Verdean Creole-speaking adults about their beliefs and behaviors regarding hypertension. Fourteen women and six men ages 35-87 were interviewed. The majority of the participants believed hypertension is symptomatic, with headache being the most common symptom. Many reported taking anti-hypertensive medication, though some took medication only when they felt symptoms. The majority were unfamiliar with a normal blood pressure reading. Most believed hypertension is related to stress and salt intake, though few reported making the recommended lifestyle changes. None of the participants communicated with physicians in their native language, relying instead on interpreters, family members or other languages to communicate. Participants identified language as a serious barrier to care. Our sample had a poor understanding of hypertension as a chronic, asymptomatic disease. Given the high prevalence of hypertension in this community, and the unavailability of Cape Verdean Creole-speaking interpreters and providers for individual patient visits, Cape Verdean patients may benefit from group education or medical visits conducted in Creole.

Relationship between patients' knowledge and medication adherence among patients with hypertension

OBJECTIVE

The purpose of this study was to investigate the relationship between knowledge on arterial hypertension (AH) and its management, and adherence to pharmaceutical treatment.

METHODS

The study included 233 patients diagnosed with AH and treated with hypotensive drugs for at least 1 year. The 8-item © Morisky Medication Adherence Scale (MMAS-8) and the Hypertension Knowledge-Level Scale (HK-LS) were used.

RESULTS

Sixty-three percent of the patients had a low level of knowledge on AH, with the smallest proportion of correct answers provided for items related to non-pharmaceutical treatment, diet, hypertension definition, and drug adherence. When compared to patients with a high level of knowledge, those with a low knowledge had lower scores in the MMAS (6.45±1.45 vs 7.08±1.04; P=0.038). Multiple-factor analysis showed that statistically significant independent determinants of good adherence included a high level of knowledge (β=0.208; P=0.001), non-pharmaceutical treatment (β=0.182; P=0.006), and frequent blood pressure measurements (β=0.183; P=0.004). The most significant factor in MMAS was knowledge in the "drug adherence" domain (ρ=0.303; P<0.001).

CONCLUSION

Patients' knowledge on hypertension is a significant independent determinant of good adherence. Other independent determinants include non-pharmaceutical treatment and regular blood pressure measurements.

IMPLICATION FOR PRACTICE

The identification of knowledge deficits as a factor contributing to lack of adherence and poor hypertension control remains a key challenge for multidisciplinary team caring for patients with hypertension.

Self-reported health beliefs, lifestyle and health behaviours in community-based patients with diabetes and hypertension

OBJECTIVE

This study describes self-reported health and lifestyle behaviours and health risk beliefs among community patients diagnosed with type 2 diabetes and hypertension.

METHODS

Patients with both type 2 diabetes and hypertension were recruited from community family practices across 3 Canadian Maritime provinces. Patients completed a survey targeting health risk beliefs, and health and lifestyle behaviours. Analyses examined differences in patient beliefs by age and sex, as well by health and lifestyle behaviour.

RESULTS

Overall, 90.8% of patients believed that controlling both blood pressure and blood glucose were important, particularly women (p<0.01), and 92.8% felt that having both conditions put them at high risk for cardiovascular problems. Older patients reported higher antihypertensive medication adherence (p<0.0001). Most (90.8%) believed that prescription drug use was most helpful for controlling blood pressure, and this belief was associated with medication adherence (p<0.0001). Overall, patients who believed in the benefits of a given lifestyle behaviour were more likely to demonstrate the behaviour.

CONCLUSION

The majority of patients surveyed were knowledgeable about their increased risk for cardiovascular problems. Patient lifestyle behaviours tended to mirror their health beliefs. These results provide important insight into the health beliefs and lifestyle behaviours of patients who receive the majority of their care in the community.

Health literacy in rural areas of China: hypertension knowledge survey

We conducted this study to determine levels and correlates of hypertension knowledge among rural Chinese adults, and to assess the association between knowledge levels and salty food consumption among hypertensive and non-hypertensive populations. This face-to-face cross sectional survey included 665 hypertensive and 854 non-hypertensive respondents in the rural areas of Heilongjiang province, China. Hypertension knowledge was assessed through a 10-item test; respondents received 10 points for each correct answer. Among respondents, the average hypertension knowledge score was 26 out of a maximum of 100 points for hypertensive and 20 for non-hypertensive respondents. Hypertension knowledge was associated with marital status, education, health status, periodically reading books, newspapers or other materials, history of blood pressure measurement, and attending hypertension educational sessions. Hypertension knowledge is extremely low in rural areas of China. Hypertension education programs should focus on marginal populations, such as individuals who are not married or illiterate to enhance their knowledge levels. Focusing on educational and literacy levels in conjunction with health education is important given illiteracy is still a prominent issue for the Chinese rural population.

Lay perspectives on hypertension and drug adherence: systematic review of qualitative research

OBJECTIVE

To synthesise the findings from individual qualitative studies on patients' understanding and experiences of hypertension and drug taking; to investigate whether views differ internationally by culture or ethnic group and whether the research could inform interventions to improve adherence.

DESIGN

Systematic review and narrative synthesis of qualitative research using the 2006 UK Economic and Social Research Council research methods programme guidance.

DATA SOURCES

Medline, Embase, the British Nursing Index, Social Policy and Practice, and PsycInfo from inception to October 2011.

STUDY SELECTION

Qualitative interviews or focus groups among people with uncomplicated hypertension (studies principally in people with diabetes, established cardiovascular disease, or pregnancy related hypertension were excluded).

RESULTS

59 papers reporting on 53 qualitative studies were included in the synthesis. These studies came from 16 countries (United States, United Kingdom, Brazil, Sweden, Canada, New Zealand, Denmark, Finland, Ghana, Iran, Israel, Netherlands, South Korea, Spain, Tanzania, and Thailand). A large proportion of participants thought hypertension was principally caused by stress and produced symptoms, particularly headache, dizziness, and sweating. Participants widely intentionally reduced or stopped treatment without consulting their doctor. Participants commonly perceived that their blood pressure improved when symptoms abated or when they were not stressed, and that treatment was not needed at these times. Participants disliked treatment and its side effects and feared addiction. These findings were consistent across countries and ethnic groups. Participants also reported various external factors that prevented adherence, including being unable to find time to take the drugs or to see the doctor; having insufficient money to pay for treatment; the cost of appointments and healthy food; a lack of health insurance; and forgetfulness.

CONCLUSIONS

Non-adherence to hypertension treatment often resulted from patients' understanding of the causes and effects of hypertension; particularly relying on the presence of stress or symptoms to determine if blood pressure was raised. These beliefs were remarkably similar across ethnic and geographical groups; calls for culturally specific education for individual ethnic groups may therefore not be justified. To improve adherence, clinicians and educational interventions must better understand and engage with patients' ideas about causality, experiences of symptoms, and concerns about drug side effects.

Evaluation of the knowledge of primary healthcare patients in Poland on the prevention of hypertension: a community study

OBJECTIVES

To investigate the knowledge of Poles on the prevention of arterial hypertension (HT) and identify the main souces of knowledge in order to make health promotion activities more effective, and thus increase the efficiency and efficacy of the Polish healthcare system.

STUDY DESIGN

Community study.

METHODS

This questionnaire study included 180 subjects (120 primary healthcare patients without a history of diagnosed HT and 60 primary care physicians).

RESULTS

The knowledge of most surveyed patients was insufficient (43%, n = 52) or sufficient (40%, n = 48) for the effective prevention of HT; 17% (n = 20) of the respondents had knowledge that was definitely sufficient, and none of the respondents had knowledge that was definitely insufficient. The patients reported that primary care physicians were the most common source of health information (67%, n = 80). Primary care physicians were also the most trusted source of information.

CONCLUSIONS

Patients' knowledge on smoking, diet and exercise is sufficient for the effective prevention of HT. The areas of insufficient knowledge for the development of HT and possible organ complications are drinking alcohol, stress, genetic factors and diabetes.

Determinants of medication adherence in hypertensive patients: an application of self-efficacy and the Theory of Planned Behaviour

Objective

The study aimed to identify the determinants of medication adherence in a population of hypertensive outpatients. The principle objective of the present study was to determine the utility of self-efficacy and the Theory of Planned Behaviour (TPB) in predicting adherence with antihypertensive medication.

Setting

An outpatient hypertension clinic at the Belfast City Hospital, Northern Ireland.

Method

Outpatients who had attended the hypertension clinic on at least one previous occasion were invited to participate in the study. Participants completed a questionnaire incorporating measures of adherence with medication, medical and sociodemographic factors, together with measures of self-efficacy and the TPB. There were no specific study exclusion criteria.

Key findings

A total of 139 participants took part in the study; 20.9% of the participants reported non-adherence with their prescribed antihypertensive medication. A statistically significant difference in self-efficacy scores between the adherent and non-adherent groups was revealed by a Mann-Whitney test, with adherent patients perceiving higher levels of self-efficacy. Regression analysis with the TPB variables revealed that adherence was predicted by intentions and subjective norms, with 41% of the variance explained. Intention was predicted by attitudes and perceived behavioural control, with 61.9% of the variance explained.

Conclusion

The present study provides support for the use of self-efficacy and the TPB in predicting medication adherence; however, further research is required on the application of the TBP in the prediction of health behaviour. These findings have implications for the design of adherence-enhancing interventions.

Social context, the struggle with uncertainty, and subjective risk as meaning-rich constructs for explaining HBP noncompliance

OBJECTIVE

To identify the reasons for which people fail to take blood-pressure-lowering medication regularly, a qualitative study was conducted.

METHODS

Interviews lasting approximately 90 min were conducted with 27 patients (15 women, 12 men) aged 40-70. The verbatim of the 27 interviews was first read and divided into segments with explanatory value. This was followed by the production of a final text in vignette form for all interviews. An integrative, analytical phase consisted of identifying trends, significant central themes, regularities, and divergences in the vignettes.

RESULTS

Analysis revealed the explanatory power that 3 broad groups of subjective meanings could hold for given medication noncompliance scenarios. These scenarios are expressing the role of: (1) stress and living conditions in the occasional skipping or deferral of medication-taking; (2) doubt as the motivating factor for transitory, irregular medication use; (3) subjective risk as the motivating factor for persistent irregular use.

CONCLUSION

Life and social contexts, doubt and risk subsume extremely meaning-rich constructs that can help identify dilemmas facing people about medication-taking.

PRACTICE IMPLICATIONS

By discussing these dimensions with their patients, health professionals will be better able to understand patient medication behaviors that sometimes run counter to their recommendations.

Incentives for lifestyle changes in patients with coronary heart disease

AIM

This paper reports a study exploring how patients in the rehabilitation phase of coronary heart disease experience facilitating and constraining factors related to lifestyle changes of importance for wellbeing and prognosis.

BACKGROUND

Lifestyle change is important but complex during rehabilitation after a myocardial infarction or angina pectoris. The intentions to perform behaviours and to experience control over facilitators and constraints are important determinants of behaviour.

METHODS

A total of 113 consecutive patients below 70 years of age (84 men and 29 women) were interviewed within 6 weeks of a cardiac event and again after 1 year. Interview transcriptions and notes taken by hand were qualitatively analysed using the phenomenographic framework. The distribution of statements among the categories identified was quantitatively analysed. The data were collected in 1998-2000.

FINDINGS

Four main categories portrayed patients' experiences of facilitating or constraining incentives for lifestyle changes. 'Somatic incentives' featured bodily signals indicating improvements/illness. 'Social/practical incentives' involved shared concerns, changed conditions including support/demand from social network, and work/social security issues. Practical incentives concerned external environmental factors in the patients' concrete context. 'Cognitive incentives' were characterized by active decisions and appropriated knowledge, passive compliance with limited insights, and routines/habits. 'Affective incentives' comprised fear of and reluctance in the face of lifestyle changes/disease, lessened self-esteem, and inability to resist temptations. Cognitive incentives mostly facilitated physical exercise and drug treatment. Social/practical incentives facilitated physical exercise and diet change. Physical exercise and diet changes were mainly constrained by somatic, social, and affective incentives.

CONCLUSION

The results illustrate important incentives that should be considered in contacts with patients and their families to improve the prospects of positively affecting co-operation with suggested treatment and lifestyle changes.

Appraisal of the knowledge of hypertensive patients and assessment of the role of the pharmacists in the management of hypertension: results of a regional survey

The objectives of the study were to appraise the knowledge which the patients have about their hypertension, and to assess the knowledge and involvement of pharmacists in the management of the hypertensive patient. All the pharmacies in the Poitou-Charentes area were invited both to participate in a training session about arterial hypertension and asked to fill in a pharmacist's questionnaire. Furthermore, each participant was required to submit a patient's questionnaire to 20 consecutive hypertensives. A total of 104 pharmacies and 1015 hypertensive patients participated in the survey. In all, 88% of the patients (n = 893) were aware of their blood pressure (BP) figures, but 68% (349/515) considered themselves wrongly, to be normalized; 39% (n = 350) only had BP figures <140/90 mmHg. They said they had been poorly informed about recommended lifestyle changes. In all, 18% (n = 185) were equipped with an automatic device. A total of 77% (n = 779) were able to give the names of their drugs without the help of the pharmacist. Treatment-related unwanted effects were reported by 8% of the patients (n = 79). Only 18% (n = 29) of the pharmacists were able to provide a correct definition of hypertension. Most of them thought hypertension was well controlled in the general population and considered that both tolerance of and compliance with antihypertensive treatment were satisfactory. They could most often (80%, n = 135) supply a SBPM device, but 58 (36%) only were able to provide relevant advice regarding the recommended procedures. In conclusion, The BP goals and the lifestyle modifications are poorly known by the hypertensives. Pharmacists' knowledge is frequently wrong and should be improved by appropriate training programmes.

Hypertension knowledge, awareness, and attitudes in a hypertensive population

OBJECTIVE

Improved recognition of the importance of systolic blood pressure (SBP) has been identified as one of the major public health and medical challenges in the prevention and treatment of hypertension (HTN). SBP is a strong independent risk factor for cardiovascular disease but no information is available on whether patients understand the importance of their SBP level. The purpose of this study was to assess HTN knowledge, awareness, and attitudes, especially related to SBP in a hypertensive population.

DESIGN/SETTING/PATIENTS

We identified patients with HTN (N=2,264) in the primary care setting of a large midwestern health system using automated claims data (International Classification of Diseases, Ninth Revision [ICD-9] codes 401.0-401.9). We randomly selected 1,250 patients and, after excluding ineligible patients, report the results on 826 completed patient telephone interviews (72% response rate [826/1,151]).

MAIN RESULTS

Ninety percent of hypertensive patients knew that lowering blood pressure (BP) would improve health and 91% reported that a health care provider had told them that they have HTN or high BP. However, 41% of patients did not know their BP level. Eighty-two percent of all patients correctly identified the meaning of HTN as "high blood pressure." Thirty-four percent of patients correctly identified SBP as the "top" number of their reading; 32% correctly identified diastolic blood pressure (DBP) as the "bottom" number; and, overall, only 30% of patients were able to correctly identify both systolic and diastolic BP measures. Twenty-seven percent of patients with elevated SBP and DBP (as indicated by their medical records) perceived that their BP was high. Twenty-four percent of patients did not know the optimal level for either SBP or DBP. When asked whether the DBP or SBP level was more important in the control and prevention of disease, 41% reported DBP, 13% reported SBP, 30% reported that both were important, and 17% did not know.

CONCLUSIONS

These results suggest that, although general knowledge and awareness of HTN is adequate, patients do not have a comprehensive understanding of this condition. For instance, patients do not recognize the importance of elevated SBP levels or the current status of their BP control. An opportunity exists to focus patient education programs and interventions on the cardiovascular risk associated with uncontrolled HTN, particularly elevated SBP levels.

Patient knowledge and awareness of hypertension is suboptimal: results from a large health maintenance organization

Patient knowledge and awareness of hypertension are important factors in achieving blood pressure control. To examine hypertensive patients' knowledge of their condition, the authors randomly surveyed 2500 hypertension patients from a large health maintenance organization; questionnaires were supplemented with clinic blood pressure measurements. Approximately 72% of the subjects completed surveys. Of patients with uncontrolled hypertension (systolic blood pressure [SBP] > or =140 mm Hg and/or diastolic blood pressure [DBP] > or =90 mm Hg), only 20.2% labeled their blood pressure as "high" and 38.4% as "borderline high". Forty percent of respondents couldn't recall their most recent clinic-based SBP and DBP values. Overall, 71.7% and 61% were unable to report a target SBP or DBP, respectively, or identify elevated targets based on the sixth report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC VI) criteria. Most patients perceived DBP to be a more important risk factor than SBP. Hypertensive patients awareness of blood pressure targets and current hypertension control status, particularly with respect to SBP, is suboptimal. The authors' findings support the need to improve patient education for better management of hypertension.

Patients' conceptions of coronary heart disease--a phenomenographic analysis

Readjustment after an event of coronary heart disease (CHD) is defined to comprise cognitive, instrumental and affective components. The cognitive dimension refers to understanding of the disease. Twenty-three patients (<60 years) with CHD were interviewed about the nature of their disease and encouraged to use their own words. The study was conducted 1 year after the event of myocardial infarction (MI) and some patients had also been revascularized. The interviews were transcribed in extenso and analysed according to the phenomenographic approach. The main finding was the great variation of conceptions revealed. Six different conceptions were found concerning CHD. Some patients comprehended MI by involving (A) blood and vessels, (B) either blood or vessel or referred to (C) risk factors/symptoms. Angina pectoris was expressed as (A) insufficient heart capacity, (B) atherosclerosis/contracted vessel or as (C) symptoms. Several patients found it difficult to expand their answers and some expressed misconceptions about the course of events. Patients' pre-existing knowledge and their way of reasoning about central phenomena related to their disease should be taken into consideration in patient education and is also applicable in individual encounters with patients.

Normal blood pressure values as perceived by normotensive and hypertensive subjects

In spite of considerable progress, the control of hypertension in most countries is still insufficient. One of the reasons may be the poor awareness of the blood pressure (BP) cutoff values that define hypertension. The aim of this report is to verify the hypothesis that patients with hypertension accept higher BP levels as normal. The study was performed during a street-based BP screening project carried out across Poland, in summer 1997. In 444 persons who voluntarily participated in Cracow's part of the project, BP was taken on the left arm, in the sitting position, after a minimum of 5 min of rest, using a semiautomated device (Digital Blood Pressure UA-702). A questionnaire investigated participants' age, weight, height, level of education, history of hypertension and perception of normal values of BP. We compared measured BP values with those perceived as normal, and with the values recommended by WHO/ISH guidelines (<140/90 mmHg). To analyse the data we used Student's t-test and linear regression with adjustment for age and body mass index (BMI). Hypertensive subjects, compared with normotensives, were less aware of normal BP values (47.4 vs 83.9%, P<0.001, for systotic blood pressure, and 77.4 vs 88.4%, P<0.01, for diastotic blood pressure). Measured BP was positively related to BP values stated as normal. A similar relation was observed for age and BMI. In conclusion, poor awareness of normal BP values in hypertensives can be an important factor hindering better BP control. Education strategies might prove to be highly effective in helping to tackle the epidemics of hypertension.

Self-blood-pressure monitoring--a questionnaire study: response, requirement, training, support-group popularity and recommendations

The objective of this study was to survey hypertensive patients' response to, requirement for and training in self-blood pressure monitoring (SBPM). A total of 222 hypertensives were invited to complete a questionnaire even when not participating in the project. Questions supplied information on demographics, monitoring frequency, convenience of attending the surgery, monitor ownership and preference for and ease of self-monitoring. Comments supplied qualitative data. Training group questionnaires supplied similar data as well as SBPM data before and after training. Of 133 respondents, a higher educated, younger, wider age range wanted to participate (76; 57.2%) and tended to self-monitor. However, only an increase in further education (FE) was associated with an increased probability of participation and inclination to self-monitor in the multivariate analyses. A positive relationship exists between age and frequency in both groups. About a sixth of respondents own monitors and ownership is correlated to FE. Although most patients found it convenient to visit the surgery, the percentage finding it convenient was lower in patients attending training sessions than in the original survey, possibly indicating that independence is important for SBPM. Younger, higher-educated patients tended to self-monitor although FE was again the significant factor. Training increased preference for the idea of SBPM, prospective monitor ownership (64.8% of non-owners) and self-monitoring intention (76.1%). Patients found recording card listed cardiovascular disease (CVD) risks valuable and 69.6% (32) wanted to establish a support group. Comments and interviews indicated haphazard knowledge, routines and uncertainty about SBPM. A standardised procedure including patient assessment, SBPM protocol and lifestyle education is needed for SBPM to be successful.

Conceptions on treatment and lifestyle in patients with coronary heart disease--a phenomenographic analysis

Twenty-three patients with an acute event of coronary heart disease (CHD) received routine care including information about medication and lifestyle changes. They were interviewed after 1 year about their conceptions concerning drug treatment and lifestyle changes. The interviews were taped, transcribed and analysed using the phenomenographic approach. Conceptions were hierarchically categorised with regard to level of understanding. The results showed that the patients' understanding of the effects and health benefits of their treatment was superficial as judged on an informed layman level. The knowledge was fragmentary and mechanistic. Several misconceptions were revealed. Few answers related to prognostic benefits. However, a conception about effects of stopping drug intake was risk of relapse. Some patients considered fate and heredity as the main causes of CHD. Thus, our patients had not achieved an adequate understanding of CHD treatment. The level of knowledge was lower than anticipated.

The nurse--a resource in hypertension care

AIM OF THE STUDY

To explore the content and structure of communication between patient and nurse at follow-up appointments concerning hypertension.

BACKGROUND

Hypertension is a chronic condition and calls for co-operation between health care providers and patients over a long period of time. One important purpose of the follow-up consultations is to transfer knowledge between patients and health care providers in order to empower patients. This is an important determinant of the quality of care.

DESIGN/METHODS

The study was based on 20 audio-recordings of actual follow-up appointments and was approved by ethics committees. The consultations took place at four different health care units for hypertensive patients.

FINDINGS

The average length of consultations was 18 minutes. In the consultations, patients initiated an average of eight new topics and nurses an average of 20. All nurses talked with patients about life style. Compared with previous studies of follow-ups with physicians, consultations with nurses addressed lifestyle factors and adherence to treatment to a higher degree. It was also observed that patients were more actively involved in interaction with nurses compared with the follow-ups with physicians.

CONCLUSIONS

Active patient participation in care is a critical factor in improving adherence to treatment. It would be of value to develop and assess a more patient-centred organization of hypertension care and thereby more individualized hypertension treatment. Nurses may have a pivot role in such care.

Reasons for adherence with antihypertensive medication

BACKGROUND

Hypertension is often insufficiently controlled in clinical practice, a prominent reason for this being poor patient adherence with therapy. Little is known about the underlying reasons for poor adherence. We set out to investigate hypertensive patients' self-reported reasons for adhering to or ignoring medical advice regarding antihypertensive medication.

METHODS

Qualitative analysis of semi-structured interviews with 33 hypertensive patients in a general-practice centre and a specialist hypertension unit in Southern Sweden. Blood-pressure measurements and laboratory measurements of antihypertensive medication were performed.

RESULTS

Nineteen out of 33 patients were classified as adherent. Adherence was a function of faith in the physician, fear of complications of hypertension, and a desire to control blood pressure. Non-adherence was an active decision, partly based on misunderstandings of the condition and general disapproval of medication, but mostly taken in order to facilitate daily life or minimize adverse effects. Adherent patients gave less evidence of involvement in care than non-adherent patients. There was no obvious relation between reported adherence, laboratory markers of adherence and blood-pressure levels.

CONCLUSIONS

The interview is a powerful tool for ascertaining patients' concepts and behaviour. To optimize treatment of hypertension, it is important to form a therapeutic alliance in which patients' doubts and difficulties with therapy can be detected and addressed. For this, effective patient-physician communication is of vital importance.

Protective effects of delapril combined with indapamide or hydrochlorothiazide in spontaneously hypertensive stroke-prone rats: a comparative dose-response analysis

In previous articles, we have shown that the combination of the angiotensin-converting enzyme (ACE) inhibitor delapril (12 mg/kg/day) and the diuretic indapamide (1 mg/kg/ day) was able to prolong the life span significantly in salt-loaded stroke-prone spontaneously hypertensive rats (SHRsp). Because this finding was partly dependent on the antagonism of salt-loading effects by pharmacologic induction of diuresis, which prevented any increase in blood pressure values, we decided to evaluate whether lower doses of the combination could be equally protective without changing the progression of hypertension. Thus, we studied several treatments with progressively lower doses of delapril (6, 3, or 1.5 mg/kg/day) combined with indapamide (0.5, 0.25, or 0.125 mg/kg/day) or hydrochlorothiazide (2.5, 1.25, or 0.625 mg/kg/day) in salt-loaded SHRsp. Salt-loaded untreated animals were considered to be the control group. In agreement with previous experiments, control rats reached 50% mortality approximately 7 weeks after the beginning of salt loading. The combination of delapril and hydrochlorothiazide at the two lowest doses was not able to delay animal death significantly, whereas treatment with delapril and indapamide at the lowest dose was effective (50% survival rate, 15 weeks). The groups treated with the highest dose of delapril and hydrochlorothiazide or with the intermediate or highest dose of delapril and indapamide did not reach 50% mortality by the end of the experiment, at 44 weeks of treatment (i.e., when animals reached age 1 year). Only the highest delapril and indapamide doses were able to increase diuresis, but for a relatively short period. None of the treatments was able to lower or control blood pressure levels adequately. Therefore, blood pressure levels by themselves were not predictive of rat mortality. In contrast, the maximal value of proteinuria in the weeks preceding death was inversely correlated with the survival time. In conclusion, this study shows that low doses of an ACE inhibitor in combination with a diuretic can be effectively protective in a model of severe hypertension, independent of any change in blood pressure levels.

Database of patients' experiences (DIPEx): a multi-media approach to sharing experiences and information

The Database of Individual Patients' Experience of illness (DIPEx) is a multimedia website and CD-ROM that links patients' experiences with evidence-based information about treatments and the illness itself and with a range of other resources that may be useful, including support groups and links to other websites. DIPEx aims to identify the questions that matter to people when they are ill and it has potential for informing patients, educating healthcare professionals, and providing a patient-centred perspective to researchers and those who manage health services.

Antihypertensive treatment and patient autonomy--the follow-up appointment as a resource for care

Since hypertension is a chronic condition which generally requires long-term commitment to pharmacological therapy as well as alterations of patient lifestyle, the patient-physician communication in the clinical setting is an important determinant of the quality of care and health outcome. The aim of the present study was to explore the structure and content of the communication between the patient and the physician, and the process of decision-making at a routine follow-up appointment for hypertension. The study was based on 51 audio-recordings of authentic consultations. Most patients had a passive role in the consultations, and initiated few topics of conversation. The few topics that the patients initiated were usually not about hypertension. Patients' questions about medication mainly referred to unwanted effects of the drugs. Little time was invested in discussing risks related to hypertension. A collaborative shared decision-making was seldom observed in the consultations.

Perceived symptoms amongst hypertensive patients in routine clinical practice- a population-based study

OBJECTIVES

To compare perceived symptoms between patients undergoing antihypertensive therapy and hypertensive patients without drug treatment, and to assess reasons for change of antihypertensive medication in routine clinical practice.

DESIGN

Population-based multicentre study. Consecutive patients from a randomized sample of centres were given a standardized questionnaire to assess symptoms as well as opinions about their antihypertensive drugs.

SETTING

Fifty-five Swedish primary health care centres and 11 clinics of internal medicine.

PATIENTS

One thousand and thirteen hypertensive patients on their individually prescribed antihypertensive medication and 13 5 without antihypertensive therapy.

MAIN OUTCOME MEASURES

Prevalence and perception of symptoms with and without antihypertensive drug therapy, changes of medication and reasons for this.

RESULTS

Amongst the group of patients on antihypertensive medication, 57% spontaneously reported having had symptoms of high blood pressure before they started their drug therapy. Amongst the patients without antihypertensive drugs, 52% reported having such symptoms. When answering direct questions about different symptoms related to current drug treatment or increased blood pressure, patients with and without medication reported symptoms to a similar extent: 80 and 85%, respectively. A majority of patients (64%) had changed their medication during the course of treatment (range 0-61 years). The mean number of changes was 2.4 times over 12 years. The most common reported cause for changing drug treatment was side-effects (42%).

CONCLUSIONS

The study shows that patients in general perceive symptoms from hypertension. Antihypertensive medication decreases the frequency and intensity of symptoms that might be related to high blood pressure but adds other symptoms linked to the medication. Changes in medication were mostly related to side-effects. The follow-up should pay attention to patients' experience of treatment. A sign of a well-managed hypertension population would be a decrease of symptoms over time.
