Relationship between health-related quality of life and blood pressure control in patients with uncontrolled hypertension

Factors associated with suboptimal adherence to antihypertensive medication: Cross-sectional study using nationally representative databases

Suboptimal adherence to antihypertensive medication is a major challenge in controlling blood pressure. However, limited studies exist on suboptimal adherence to hypertension, especially in Korea. This study investigates factors associated with suboptimal adherence, including non-treatment and non-adherence. Study populations were collected from the Korea National Health and Nutrition Examination Survey (KNHANES) from 2007 to 2021. Participants were classified into three groups based on treatment and adherence to antihypertensive medication using a self-reported questionnaire. Multivariable adjusted logistic regression analysis was performed using KNHANES data to investigate associations for suboptimal adherence with covariates. In KNHANES, the adherent, non-adherent, and non-treatment groups consisted of 13,831 (92.8 %), 460 (3.1 %), and 612 (4.1 %) subjects, respectively. In the adjusted model, age, hypertension diagnosis duration, diabetes, dyslipidemia, and high hemoglobin levels were associated with receiving treatment. Older age, longer hypertension diagnosis duration, comorbid diabetes mellitus, and ischemic heart disease were associated with adherence. This study showed the characteristics of non-adherent and non-treatment hypertensive patient groups in Korea. Based on this study, further individualized health interventions are required.

Quality-of-life and beliefs about medication in relation to a therapy adherence intervention in resistant hypertension: the Resistant HYpertension: MEasure to ReaCh Targets trial

OBJECTIVE

To assess the impact of personalized feedback on therapy adherence testing results on quality of life and beliefs about medication in patients with resistant hypertension, as well as to identify patient-oriented predictors of therapy adherence.

METHODS

This study was a prespecified post hoc analysis of the multicenter randomized controlled trial Resistant HYpertension: MEasure to ReaCh Targets (RHYME-RCT). Patients were randomized to a personalized feedback conversation on measured antihypertensive drug levels additional to standard-of-care, or standard-of-care only. The primary outcomes consisted of EuroQol EQ-5D-5L and Beliefs about Medicine Questionnaire (BMQ) scores at 12 months.

RESULTS

A total of 56 patients with median age 61.5 [25th-75th percentile: 55.8-69.3] years (21.4% women) were included. Mean blood pressure ±SD was 149.8/84.1 ± 14.9/13.8 mmHg while being on a median of 5.6 [4.8-7.3] defined daily dosages (DDD) of antihypertensive drugs. At 12 months, no differences were observed in EQ-5D-5L index (0.81 [0.69-0.89] vs. 0.89 [0.73-1.00]; P  = 0.18) and visual analogue scale score on general patient-perceived health (70 [60-80] vs. 70 [60-82]; P  = 0.53) between the intervention-arm and the standard-of-care only-arm. Likewise, individual EQ-5D-5L domain scores and BMQ scores did not differ between both arms. Irrespective of the intervention, independent positive predictors of the percentage adherence were patient age, EQ-5D-5L index score, BMQ-specific necessity score and concern score, whereas the total number of drugs prescribed was a negative predictor.

CONCLUSION

Within this prespecified subanalysis of the randomized RHYME-RCT trial, implementation of a personalized feedback conversation targeting therapy adherence did not improve health-related quality-of-life and beliefs about medication in patients with resistant hypertension.

Impact of hospital pharmacist-delivered individualised pharmaceutical service intervention on clinical and patient-reported outcomes in patients with hypertension: a randomised controlled trial

OBJECTIVES

Patients with hypertension in Nepal are often known to have poor medication adherence and quality of life. This randomised controlled trial aimed to evaluate the impact of a hospital pharmacist-delivered individualised pharmaceutical service (P-DIPS) intervention on blood pressure, medication adherence and health-related quality of life (HRQoL) among patients with hypertension in a hospital setting in Nepal.

METHODS

In an open trial, 56 adult patients with hypertension who had been receiving antihypertensive medication for ≥6 months were randomly allocated to a control group (n=28) which received the usual care and an intervention group (n=28) which received a P-DIPS along with the usual care. The difference in blood pressure, medication adherence and HRQoL between the two groups at baseline, 2 and 4 months was compared using the Mann-Whitney U test, independent t-test or χ2 tests.

RESULTS

Participants were mostly ≥40 years (86%) and female (57%). There were no significant differences in the baseline characteristics between the control (C) and intervention (I) groups. At 2 months, the two groups had a significant improvement in the median (IQR) Morisky-Green-Levine (MGL) Medication Adherence Score (I=1 (2) vs C=2 (2); p<0.001) and the median (IQR) mental component of HRQoL (I=43.6 (9.5) vs C=37.5 (8.6); p=0.013). At 4 months, there were significant differences in the median (IQR) values of all the outcome measures between the groups (systolic blood pressure: I=125 (10) mmHg vs C=130 (15) mmHg, p=0.008; diastolic blood pressure: 80 (14) mmHg vs 90 (10) mmHg, p=0.012; MGL score: I=1 (1) vs C=2 (1), p<0.001; physical component of HRQoL: 45.0 (9.0) vs 40.3 (8.2), p=0.046; and mental component of HRQoL: 47.1 (11.1) vs 38.8 (8.5), p=0.003).

CONCLUSIONS

The findings suggest that a P-DIPS intervention in the hospital setting of Nepal has a significant potential to improve blood pressure, medication adherence and HRQoL in patients with hypertension.

Dietary fiber intake is positively associated with health-related quality of life in patients with hypertension: The mediating role of anxiety in mental component summary

Few studies have focused on the exploration of the relationship between dietary fiber intake (DFI) and health-related quality of life (HRQoL) and its mediators in hypertensive patients. This study is a cross-sectional survey and the data were obtained from hypertensive patients from Suzhou, China. The DFI, office systolic blood pressure and diastolic blood pressure, anxiety and depression, and HRQoL were investigated. We hypothesized that blood pressure, anxiety, and depression mediated the association between DFI and HRQoL, and used Pearson correlations, linear regression, and bootstrap tests to validate this relationship. A total of 211 hypertensive patients aged 20 to 64 years were included in this study. The average DFI was 12.4 ± 5.2 g/d, and the scores of physical component summary and mental component summary (MCS) were 46.5 ± 6.1 and 46.4 ± 6.4, respectively. DFI was positively correlated with physical component summary (r = 0.17, p = 0.014) and MCS (r = 0.27, P < .001). After controlling for sociodemographic and clinical characteristics, neither systolic blood pressure nor diastolic blood pressure showed mediating effects in the mediated model of DFI on MCS, whereas anxiety (b = -0.30; 95% confidence interval, -0.41 to -0.18) fully mediated the improvement in MCS by DFI (F = 11.14, P < .001). Because the MCS of HRQoL encompassed the assessment of depression, we did not analyze the mediating effect of depression in this model in order to avoid variable duplication. The decreased DFI is a risk factor for lower HRQoL, and anxiety mediated the relationship between DFI and MCS. Further research should focus on increasing DFI and reducing anxiety levels in hypertensive patients to improve their quality of life.

High Prevalence of Uncontrolled Hypertension Among Afghan Hypertensive Patients: A Multicenter Cross-Sectional Study

Background

Despite striking advances in the management of hypertension, blood pressure (BP) control remains suboptimal worldwide. Sustainable Development Goals (SDGs) call for 80% control rates by 2030, highlighting the urgency for improvements in hypertension control.

Objective

We aimed to determine the prevalence of uncontrolled hypertension (≥140/90 mmHg) and assess its associated factors in Afghan hypertensive patients.

Methods

We conducted this multicenter cross-sectional study at three Afghan public hospitals in Afghanistan. We recruited hypertensive patients (n=950) on antihypertensive medications (AHMs) from August to December 2022. We analyzed only complete datasets (853). We employed the 14-item Hill-Bone compliance scale to assess compliance with AHMs. We performed multivariable logistic regression analyses to determine factors associated with uncontrolled hypertension.

Results

The mean age (±SD) of the patients was 47.5 (± 9.5) years and males constituted 50.5% (431) of the study sample. The prevalence of uncontrolled hypertension in this study was 77.3% (95% CI: 74.2-79.9%). Factors associated with uncontrolled hypertension and their adjusted OR (95% CI) were physical inactivity: 3.45 (1.87-6.35), current smoking: 3.04 (1.50-6.15), high salt intake: 3.57 (1.9-6.7), presence of comorbid medical disease: 2.22 (1.20-4.08), higher BMI: 3.32 (1.12-9.88), poor compliance to AHMs: 8.50 (4.62-15.6), and presence of depressive symptoms: 1.99 (1.2-3.27).

Conclusion

The prevalence of uncontrolled hypertension was high in the present study. Factors associated with uncontrolled hypertension may epitomize potential targets for public/individual health interventions in Afghanistan.

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.

The Impact of Risk Factor Control on Health-Related Quality of Life in Individuals with High Cardiovascular Disease Risk: A Cross-sectional Study Based on EQ-5D Utility Scores in Inner Mongolia, China

Objectives

To assess the impact of cardiovascular disease (CVD) risk factor control on health-related quality of life (HRQoL), as well as the other influencing factors of HRQoL among high CVD risk individuals.

Methods

From 2015 to 2017, residents of six villages or communities in Inner Mongolia, selected using a multi-stage stratified cluster random sampling method, were invited to complete a questionnaire and undergo physical examination and laboratory testing. We selected participants whose predicted 10-year risk for CVD exceeded 10% as those with high CVD risk. HRQoL in individuals with high CVD risk was investigated based on the EuroQol-5 Dimension (EQ-5D) scale. The Chinese utility value integral system was used to calculate EQ-5D utility scores, and the Tobit regression model was used to analyze the influencing factors of HRQoL among individuals with high CVD risk.

Results

Of 13,359 participants with high CVD risk, 65.63% reported no problems in any of the five dimensions; the most frequently reported difficulty was pain/discomfort. The median utility score was 1.000 (0.869, 1.000). Participants with hypertension, and uncontrolled glycemic and blood lipids had lower HRQoL. In addition, sex, age, living environment, education level, household income, and medical insurance were influencing factors of HRQoL.

Conclusion

Sex, age, living environment, education level, household income, medical insurance, hypertension, and whether glycemic and blood lipids control or not are related to HRQoL of high CVD risk individuals.
