Medication Adherence and Blood Pressure Control Among Hypertensive Patients With Coexisting Long-Term Conditions in Primary Care Settings: A Cross-Sectional Analysis

A tryst of 'blood pressure control- sex- comorbidities': the odyssey of basic public health services in Yunnan in quest for truth

BACKGROUND

The Basic Public Health Service (BPHS), a recently announced free healthcare program, aims to combat the most prevalent Noncommunicable Disease-"Hypertension" (HTN)-and its risk factors on a nationwide scale. In China, there is a rife that HTN less impacts women during their lifetime. We, therefore, aimed to evaluate the sex disparity in hypertension patients with comorbidities among south-west Chinese and the contribution of BPHS to address that concern.

METHODS

We have opted for a multistage stratified random sampling method to enroll hypertensive patients of 35 years and older, divided them into BPHS and non-BPHS groups. We assessed the sex disparity in HTN patients with four major comorbidities- Dyslipidemia, Diabetes Mellitus (DM), Cardiovascular Disease (CVD), and Chronic Kidney Disease (CKD), and descriptive data were compiled. Odds ratios from logistic regression models estimated the effectiveness of BPHS in the management of HTN with comorbidities.

RESULTS

Among 1521 hypertensive patients,1011(66.5%) were managed in the BPHS group. The proportion of patients who had at least one comorbidity was 70.7% (95% confidence interval [CI]: 66.3-76.8%), patients aged 65 years and older were more likely to have coexisting comorbidities. Participants who received the BPHS showed significant blood pressure (BP) control with two comorbidities (odds ratio [OR] = 2.414, 95% CI: 1.276-4.570), three or more (OR = 5.500, 95%CI: 1.174-25.756). Patients with dyslipidemia and DM also benefited from BPHS in controlling BP (OR = 2.169, 95% CI: 1.430-3.289) and (OR = 2.785, 95%CI: 1.242-6.246), respectively. In certain high-income urban survey centers, there was sex differences in the HTN management provided by BPHS, with men having better BP control rates than women.

CONCLUSIONS

Perhaps this is the first study in China to succinctly show the effectiveness and sex disparity regarding "management of hypertensive comorbidities". This supports that the BPHS program plays a pivotal role in controlling BP, therefore should recommend the national healthcare system to give women a foremost priority in BPHS, especially to those from low-socioeconomic and low-scientific literacy regions.

Comorbid status of patients with hypertension

Aim. To establish age and gender characteristics, nosological structure of comorbidity among persons 2099 years with hypertension. Materials and methods. The study is based on data from 21 514 electronic health records of the population (2099 years old) with hypertension, mean age 63.0 years, 68.2% women. Diseases associated with hypertension with a frequency above 10% were analyzed. Results. In the sample of people with hypertension, concomitant diseases were detected in 82.7% of cases, 1 disease accompanies 21.0% of the sample with hypertension, 2 diseases 17.9%, 3 diseases 14.0%, 4+ diseases 29.8%. The frequency of association of hypertension with 1 concomitant disease at the 2029 years is 60.8% of cases, at 3039 years 65.1%, at 4049 years 73.9%, at 5059 years 81.1%, 6069 years 85.8%, 7079 years 87.3%, 80+ years 86.2% of cases. Among women with hypertension, the average number of concomitant diseases is higher compared to men (3.47 vs 2.4 cases; p0.001). Among young and middle-aged people, hypertension in most cases is associated with osteochondrosis, osteoarthritis, chronic pancreatitis, gastritis and duodenitis, retinal diseases, thyroid diseases, the female with hypertension accompanied by benign breast disease and menopausal disorders. Hypertension in the elderly is most often associated with cerebrovascular disease, coronary heart disease, diabetes mellitus, senile cataract, but osteochondrosis and osteoarthritis also do not lose their relevance. Conclusion. The existing system of organization of medical care cannot meet the needs of patients with comorbidity, which indicates the need to reorient medical care towards patient-centered care.

Disparities in Prevalence and Barriers to Hypertension Control: A Systematic Review

Controlling hypertension (HTN) remains a challenge, as it is affected by various factors in different settings. This study aimed to describe the disparities in the prevalence and barriers to hypertension control across countries of various income categories. Three scholarly databases-ScienceDirect, PubMed, and Google Scholar-were systematically examined using predefined search terms to identify potentially relevant studies. Original research articles published in English between 2011 and 2022 that reported the prevalence and barriers to HTN control were included. A total of 33 studies were included in this systematic review. Twenty-three studies were conducted in low and middle-income countries (LMIC), and ten studies were from high-income countries (HIC). The prevalence of hypertension control in the LMIC and HIC studies ranged from (3.8% to 50.4%) to (36.3% to 69.6%), respectively. Concerning barriers to hypertension control, patient-related barriers were the most frequently reported (n = 20), followed by medication adherence barriers (n = 10), lifestyle-related barriers (n = 8), barriers related to the affordability and accessibility of care (n = 8), awareness-related barriers (n = 7), and, finally, barriers related to prescribed pharmacotherapy (n = 6). A combination of more than one category of barriers was frequently encountered, with 59 barriers reported overall across the 33 studies. This work reported disparities in hypertension control and barriers across studies conducted in LMIC and HIC. Recognizing the multifactorial nature of the barriers to hypertension control, particularly in LMIC, is crucial in designing and implementing customized interventions.

Medication Adherence Among Multimorbid Patients With Polypharmacy and Its Relation to Social Support at National Guard Primary Health Care Centers, Riyadh

OBJECTIVE

The aim of the present study was to estimate the prevalence of nonadherence to medication in multimorbid patients with polypharmacy and its relationship to social support in primary healthcare centers in Riyadh, Saudi Arabia.

METHODS

We conducted a cross-sectional, convenience-sample, non-randomized study in three primary healthcare centers managed by National Guard Health Affairs. The participants included 417 adult patients - (a) with two or more chronic illnesses and (b) who were taking two or more medications. The primary outcome variable was the prevalence of medication nonadherence in multimorbid patients with polypharmacy as measured by the modified Morisky Medication Adherence Scale (MMAS-8). The second main variable was the impact of functional social support, as measured by the Duke-UNC Functional Social Support Questionnaire (FSSQ), on medication adherence.

RESULTS

The level of medication adherence was low for 194 (46.5%) of the 417 patients, medium for 127 (30.5%), and high for 96 (23%). There were 256 (61.4%) male participants and 161 (38.6%) females, and their mean age was 59.15 (SD ± 11.186) years. Additionally, 171 (41%) participants used two or three medications, 127 (30.5%) used four or five medications, and 119 (28.5%) used more than five medications; 178 (42.7%) of the patients had two comorbidities, 136 (32.9%) had three comorbidities, 69 (16.5%) had four comorbidities, and 31 (7.5%) had five comorbidities. Some social support data from the Duke-UNC Functional Social Support Questionnaire (FSSQ) was missing for 58 (13.9%) of the participants. Among the rest of the sample, reported levels of social support levels were high for 246 (59%) patients, medium for 101 (24.2%), and low for 12 (2.9%) patients. None of the differences between social support and medication adherence were statistically significant. However, 61 (24.8%) patients reported both high social support and high medication adherence; 173 (48.2%) had low social support and low medication adherence (p = 0.470).

CONCLUSION

We found that medication nonadherence in multimorbid patients with polypharmacy was high (46.5%). Although there were no statistically significant relationships between social support and medication adherence, certain patient characteristics were associated with low medication adherence - age over 60 years, male gender, and number of medications.

Global Burden, Regional Differences, Trends, and Health Consequences of Medication Nonadherence for Hypertension During 2010 to 2020: A Meta-Analysis Involving 27 Million Patients

Background

Nonadherence to antihypertensive medications is the leading cause of poor blood pressure control and thereby cardiovascular diseases and mortality worldwide.

Methods and Results

We investigated the global epidemiology, regional differences, and trend of antihypertensive medication nonadherence via a systematic review and meta‐analyses of data from 2010 to 2020. Multiple medical databases and clinicaltrials.gov were searched for articles. Observational studies reporting the proportion of patients with anti‐hypertensive medication nonadherence were included. The proportion of nonadherence, publication year, year of first recruitment, country, and health outcomes attributable to antihypertensive medication nonadherence were extracted. Two reviewers screened abstracts and full texts, classified countries according to levels of income and locations, and extracted data. The Joanna Briggs Institute prevalence critical appraisal tool was used to rate the included studies. Prevalence meta‐analyses were conducted using a fixed‐effects model, and trends in prevalence were analyzed using meta‐regression. The certainty of evidence concerning the effect of health consequences of nonadherence was rated according to Grading of Recommendations, Assessment, Development and Evaluations. A total of 161 studies were included. Subject to different detection methods, the global prevalence of anti‐hypertensive medication nonadherence was 27% to 40%. Nonadherence was more prevalent in low‐ to middle‐income countries than in high‐income countries, and in non‐Western countries than in Western countries. No significant trend in prevalence was detected between 2010 and 2020. Patients with antihypertensive medication nonadherence had suboptimal blood pressure control, complications from hypertension, all‐cause hospitalization, and all‐cause mortality.

Conclusions

While high prevalence of anti‐hypertensive medication nonadherence was detected worldwide, higher prevalence was detected in low‐ to middle‐income and non‐Western countries. Interventions are urgently required, especially in these regions. Current evidence is limited by high heterogeneity.

Medication Adherence Among Patients with Multimorbidity in the United Arab Emirates

BACKGROUND

Multimorbidity, defined as having two or more chronic diseases, has a major impact on public health and Sustainable Development Goals (SDG). This study aims to assess the prevalence of medication adherence and associated factors among patients with multimorbidity.

METHODS

A questionnaire-based, cross-sectional survey was conducted by a trained interviewer across patients with multimorbidity attending outpatient clinics in two tertiary referral hospitals in the United Arab Emirates (UAE). Demographic and social variables and the outcome (self-reported adherence to long-term medication) were measured using the General Medication Adherence Scale (GMAS). Multiple logistic regression was used to assess medication adherence and associated factors.

RESULTS

From a total of 630 participants included in this study, the estimated prevalence of high medication adherence is 78.57% (±1.63478) with a 95% confidence interval (CI) [75.19, 81.61]. The odds of high medication adherence increased with age. The odds of high medication adherence for patients aged 66 years and older than those aged 19-35 years is adjusted odds ratio (AOR) = 3.880, with a 95% CI [1.124, 13.390]. Patients with income more than 50,000 had the odds, AOR = 5.169 with a 95% CI [1.282, 20.843], compared to those earning less than 10,000 Dirhams (AED). Patients aged 36-65 with health insurance coverage had higher medication adherence than groups on the other end. The number of current medications is significantly (p-value = 0.027) associated with high medication adherence with the odds of high medication adherence, AOR = 4.529 with a 95% CI [1.184, 17.326], the highest for those currently taking four medications.

CONCLUSION

This study highlights younger population having multimorbidity in the context of an increasing life expectancy and suboptimal therapeutic outcomes. Furthermore, the study highlights multimorbidity is associated with low medication adherence and out-of-pocket payment, and non-availability of insurance is a major hindrance to medication adherence.

Clinicians' prescribing pattern, rate of patients' medication adherence and its determinants among adult hypertensive patients at Jimma University Medical Center: Prospective cohort study

Background

Many studies conducted in the past focused on patients’ sociodemographic factors and medical profiles to identify the determinants of suboptimal blood pressure control. However, prescribing patterns and clinicians’ adherence to guidelines are also important factors affecting the rate of blood pressure control. Therefore, this study aimed to determine clinicians’ prescribing patterns, patients’ medication adherence, and its determinants among hypertensive patients at Jimma University Medical Center.

Methods

A general prospective cohort study was conducted among hypertensive patients who had regular follow-up at Jimma university ambulatory cardiac clinic from March 20, 2018, to June 20, 2018. Patients’ specific data was collected with a face-to-face interview and from their medical charts. Clinicians’ related data were collected through a self-administered questionnaire. Data were analyzed using SPSS version 21.0. Bivariate and multivariable logistic regression analyses were done to identify key independent variables influencing patients’ adherence. P-Values of less than 0.05 were considered statically significant.

Results

From the total of 416 patients, 237(57.0%) of them were males with a mean age of 56.50 ± 11.96 years. Angiotensin-converting enzyme inhibitors were the most frequently prescribed class of antihypertensives, accounting for 261(63.7%) prescriptions. Combination therapy was used by the majority of patients, with 275 (66.1%) patients receiving two or more antihypertensive drugs. Patients’ medication adherence was 46.6%, while clinicians’ guideline adherence was 44.2%. Patients with merchant occupation (P = 0.020), physical inactivity (P = 0.033), and diabetes mellitus co-morbidity (P = 0.008) were significantly associated with a higher rate of medication non-adherence.

Conclusion

The rate of medication adherence was poor among hypertensive patients. Physicians were not-adherent to standard treatment guideline. The most commonly prescribed class of drugs were angiotensin-converting enzyme inhibitors. Effective education should be given to patients to improve medication adherence. Prescribers should be trained on treatment guidelines regularly to keep them up-to-date with current trends of hypertension treatment and for better treatment outcomes.

Associations between Socio-Demographic Factors and Hypertension Management during the COVID-19 Pandemic: Preliminary Findings from Malaysia

The perspectives of hypertensive patients on the state of hypertension control during the ongoing pandemic restrictions have not been extensively studied in Malaysia. Therefore, this study aimed to assess the impact of socio-demographic factors, health literacy, and adherence on the overall hypertension management in a group of Malaysian hypertensive patients during the COVID-19 pandemic. An anonymous, online cross-sectional study was conducted over three months that involved a group of Malaysian adults with hypertension. A validated, self-administered 30-item questionnaire was prepared in Malay and English languages on Google Forms. The link was then distributed to participants on social media (Facebook and WhatsApp). Following survey validation, a pilot study with 30 participants who met the inclusion criteria was carried out. The total scores for health literacy, adherence, and pandemic impact on hypertension control were calculated and compared across all independent variables. In a total of 144 study participants, controlled blood pressure was reported in 77% (N = 111). There were good levels of adherence and health literacy scores but moderate levels of pandemic impact scores. The total adherence scores showed a statistically significant difference between age groups (χ² = 6.48, p = 0.039) and those who reported having controlled and uncontrolled blood pressure (U = 1116, p = 0.001). Moreover, the analysis revealed statistically significant differences in total pandemic impact scores based on the age group (χ² = 15.008, p = 0.001), household income (χ² = 6.887, p = 0.032), employment (U = 1712, p = 0.006), and marital status (U = 520.5, p < 0.001). The youngest age group (18-39) years, the lowest income group, unemployed and unmarried individuals, had significantly higher pandemic impact scores. This denotes that those individuals were more prone to be negatively affected by the pandemic regarding their hypertension management. Most participants reported relatively controlled blood pressure and good levels of health literacy as well as adherence amidst the pandemic. To a moderate extent, study participants perceived that the pandemic had a negative effect on hypertension management. The perceived negative impact of the pandemic was attributed to several socio-demographic factors, such as age, household income, employment, and marital status.

Prevalence and predictors of medication non-adherence among people living with multimorbidity: a systematic review and meta-analysis

OBJECTIVES

This systematic review aimed to describe medication non-adherence among people living with multimorbidity according to the current literature, and synthesise predictors of non-adherence in this population.

METHODS

A systematic review was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses. PubMed, EMBASE, CINAHL and PsycINFO were searched for relevant articles published in English language between January 2009 and April 2019. Quantitative studies reporting medication non-adherence and/or predictors of non-adherence among people with two or more chronic conditions were included in the review. A meta-analysis was conducted with a subgroup of studies that used an inclusive definition of multimorbidity to recruit participants, rather than seeking people with specific conditions. Remaining studies reporting prevalence and predictors of non-adherence were narratively synthesised.

RESULTS

The database search produced 10 998 records and a further 75 were identified through other sources. Following full-text screening, 178 studies were included in the review. The range of reported non-adherence differed by measurement method, at 76.5% for self-report, 69.4% for pharmacy data, and 44.1% for electronic monitoring. A meta-analysis was conducted with eight studies (n=8949) that used an inclusive definition of multimorbidity to recruit participants. The pooled prevalence of non-adherence was 42.6% (95% CI: 34.0 - 51.3%, k=8, I²=97%, p<0.01). The overall range of non-adherence was 7.0%-83.5%. Frequently reported correlates of non-adherence included previous non-adherence and treatment-related beliefs.

CONCLUSIONS

The review identified a heterogeneous literature in terms of conditions studied, and definitions and measures of non-adherence used. Results suggest that future attempts to improve adherence among people with multimorbidity should determine for which conditions individuals require most support. The variable levels of medication non-adherence highlight the need for more attention to be paid by healthcare providers to the impact of multimorbidity on chronic disease self-management.

Medication adherence and related determinants in older people with multimorbidity: A cross-sectional study

AIM

Identify the medication adherence determinants in older adults with multimorbidity and polypharmacy.

MATERIALS AND METHODS

A cross-sectional study was conducted in a non-probabilistic sample of 245 adults ≥65 years recruited in a general medical ward of one teaching hospital. Data were collected during hospital stay using a face-to-face interview based on a set of validated questionnaires, such as the measure treatment adherence, the beliefs about medicines questionnaire-specific and the geriatric depression scale. Descriptive and multiple linear regression analysis were performed.

RESULTS

Participants' mean age was 78.32 (SD: 6.95) years and 50.6% were women. Older adults lived with an average of 7.51 (SD: 1.95) chronic conditions and had a mean of 7.95 (min. 4; max. 18) medications prescribed. The proportion of older adults adherent to medication was 43.7%. Depression ( β  = -0.142; p = 0.031), beliefs about treatment necessity ( β  = 0.306; p = 0.001) and concerns about the medication ( β  = -0.204; p = 0.001) were found as independent determinants of adherence.

CONCLUSION

Self-reported medication non-adherence appears to be common in older adults with multimorbidity and polypharmacy. Depression, necessity and concerns should be considered when assessing medication non-adherence in practice. This study will also contribute to develop an intervention to manage adherence in older people, as part of a doctoral research project.

Associations between mental health disorder and management of physical chronic conditions in China: a pooled cross-sectional analysis

Physical non-communicable diseases (NCDs) and mental health disorders are a rapidly increasing health burden in low-and middle-income countries. This study aims to examine the relationships between mental health disorders and cascade of care in managing four common physical NCDs (hypertension, diabetes, dyslipidemia, chronic kidney disease) in China. We utilized two waves of nationally-representative China Health and Retirement Longitudinal Study (CHARLS 2011, 2015) of older adult population aged 45 and above. A series of unadjusted and adjusted mixed-effect logistic regression was applied to evaluate the association between presence of mental health disorder and physical chronic disease awareness, treatment, and control. We found that the odds of dyslipidemia (AOR 1.81, 95% CI 1.36–2.39) and kidney disease awareness (AOR 2.88, 95% CI 2.12–3.92) were higher for individuals with mental chronic conditions, compared to those without mental chronic conditions. The odds of having hypertension treatment was higher for subjects with mental health disorder, compared to those without (AOR 1.32, 95% CI 1.02–1.70). The odds of having physical chronic conditions controlled was not significantly associated with having mental chronic conditions (P > 0.05). These results indicated that adults with mental health disorder have a greater likelihood of awareness of having dyslipidemia and kidney disease, and receiving treatment for hypertension. Strategies to address the growing burden of physical-mental NCDs in China should include efforts to improve management of patients with comorbid health condition and improve access to continual high-quality treatment after the first diagnosis.

Prevalence of non-adherence to antihypertensive medication in Asia: a systematic review and meta-analysis

Background Hypertension and its associated complications are one of the leading causes of morbidity and mortality in Asia. Racial disparities in terms of treatment outcomes among hypertension patients have been reported in literature with Asian patients resulting in poorer treatment outcomes. Non-adherence to antihypertensive therapy is frequently associated with poor treatment outcomes. Aim of the review The aim of this review was to estimate the prevalence of non-adherence to antihypertensive medications among patients with hypertension residing in Asia. Method PubMed, Google Scholar, MEDLINE, Embase, Scopus, CINHAL and Cochrane library were searched for studies published between 2000 and 2019 involving hypertensive patients. Studies investigating the prevalence of medication non-adherence in Asian countries, rated either good or fair on National Institute of Health quality assessment tool and published in English language were included in our review. Data were extracted by one author and checked by another using a structured and pilot-tested data extraction sheet. A random-effects meta-analysis was performed using STATA version 14.3®. Results Sixty-Six studies from 22 Asian countries including 2,532,582 hypertensive patients were included. Mean (± SD) age of participants was 58(± 6) years. Overall, the estimated prevalence of non-adherence to antihypertensive medication in Asia was 48% (95% CI: 41-54, P = 0.001). The rate of non-adherence was higher among females 49% (95% CI: 41-56, P = 0.001) compared to males 47% (95% CI: 40-53, P = 0.001). As per the region, the highest prevalence of non-adherence was found in South Asia 48% (95% 44-51, P = 0.877) followed by East Asia 45% (31-59, P = 0.001) and the Middle East 41 (95% 30-52, P = 0.001). Similarly, higher rate of non-adherence was observed in low and lower middle-income countries i.e. 50% (95% CI: 47-54, P = 0.220) as compare to upper-middle and high-income countries i.e. 37% (95% CI: 25-49, P = 0.001) and 44% (95% CI: 29-59, P = 0.001) respectively. Conclusion The prevalence of non-adherence to antihypertensive medication is high in Asia. This may partly explain poor treatment outcomes and incidence of higher mortality rate in Asia frequently reported in the literature. There is a need to implement appropriate policies and clinical practices to improve medication adherence.

Assessing Barriers to and Level of Adherence to Hypertension Therapy among Palestinians Living in the Gaza Strip: A Chance for Policy Innovation

Introduction

Hypertension is a major health concern, especially in low-income countries. Nonadherence and poor or no persistence in adhering to hypertension treatment regimens result in uncontrolled high blood pressure, increasing rates of mortality and morbidity, and preventable healthcare costs. The aim of this study was to assess the level of adherence and barriers to treatment regimens among hypertensive patients living in the Gaza Strip, Palestine.

Methods

A convenience sample of 648 participants completed the Hill-Bone Compliance to High Blood Pressure Therapy Scale. The great majority of participants (n = 521, 80.4%) was highly adherent to their treatment regimen, 123 participants (18.98%) were classified as moderately nonadherent, and 4 (0.62%) participants were classified as highly nonadherent to their hypertension treatment regimen. Participants of this study showed the highest adherence rate to the domain of medication adherence (mean of 1.42 out of 4) followed by appointment keeping (mean 1.8), while they were least adherent to diet (mean of 2.18). The greatest three barriers to adherence to the recommended treatment regimen reported by participants were inability to exercise, inability to resist fast and fried food, and inability to keep themselves away from salty foods.

Conclusion

Overall adherence to medication in Gaza was surprisingly good in patients with a diagnosis of hypertension for at least one year. However, adherence to lifestyle advice or dietary regimes remains poor. A combination of interventions using low-cost mobile technology, combined with face-to-face interventions by healthcare professionals, can be applied to improve adherence to hypertension treatment regimens in order to reduce the consequences of uncontrolled blood pressure.

Predictive Performance of Pender's Health Promotion Model for Hypertension Control in Iranian Patients

Objective

The main aim of this study was to investigate predictive factors of adherence to the hypertension control therapeutic and lifestyle recommendations in a sample of Iranian patients based on the constructs of Pender’s health promotion model.

Patients and Methods

The cross-sectional study was performed on the 380 hypertensive patients who were referred to the health centers, the emergency and internal diseases departments of the Bagheralolom Hospital, and the cardiologists’ offices in the city of Ahar, North West of Iran. Data were collected using a researcher designed questionnaire based on the Pender’s health promotion model. The Pearson correlation test, multivariate linear regression, and independent t-test were used for data analysis.

Results

Mean age of the recruited patients was 52.94 (SD=12.8). Perceived benefits, perceived barriers, situational influences, and interpersonal influences (adjusted R²= 0.525) explained 52.5% of the observed variation in adherence to hypertension control recommendations.

Conclusion

Successful hypertension control in patients with chronic morbidity need to be based on sound data about major determinants of the relevant health/illness behaviors. The study findings revealed that the Pender’s health promotion model could be applicable as a theoretical framework to identify major determinants of adherence to hypertension control recommendations. Future cross-cultural validation of the study findings in more representative and larger sample sizes could add to the legitimacy of the evidence surrounding self-care practices in hypertensive patients.

Antihypertensive Effectiveness of Perindopril Arginine and Indapamide Single-Pill Combination According to Body Mass Index: Findings from the FORSAGE Study

Introduction

Overweight and obesity are increasing worldwide and are associated with an increased risk for cardiovascular disease (CVD). The aim of this study was to examine the burden of CVD risk factors among normal weight, overweight, and obese subjects with hypertension, and to evaluate the effectiveness of switching to a single-pill combination (SPC) of perindopril arginine/indapamide for blood pressure (BP) control in overweight and obese subjects treated in routine clinical practice.

Methods

FORSAGE was a 3-month, multicenter, observational, open-label study conducted in Russian patients with uncontrolled arterial hypertension under previous antihypertensive therapy. Subjects were switched to the full-dose perindopril arginine 10 mg/indapamide 2.5 mg SPC. BP was assessed at 2 weeks, 1 month, and 3 months, and serum creatinine and general health status at 3 months. The present post hoc analysis of the FORSAGE study results explored the effectiveness of perindopril arginine/indapamide SPC in patients with arterial hypertension with regard to baseline body mass index (BMI): normal (< 25 kg/m²), overweight (25 ≤ BMI < 30 kg/m²), and obese (≥ 30 kg/m²).

Results

A total of 1969 patients were recruited, but BMI data were available for 1963 patients, two-thirds of whom were women. The distribution of BMI groups was as follows: < 25 kg/m² (16.7%), overweight (48.7%), and obese (34.7%). Overweight or obese patients had more concomitant diseases such as diabetes mellitus or history of stroke, higher BP levels, serum cholesterol and creatinine, and lower glomerular filtration rates. Switching to perindopril arginine/indapamide SPC was associated with a statistically significant reduction in BP as early as the second week of treatment. At 3 months, systolic blood pressure (SBP)/diastolic blood pressure (DBP) had decreased significantly by 39.3/18.8 mmHg in the normal BMI group, 39.8/18.8 mmHg in overweight, and 39.4/18.7 mmHg in obese groups. The magnitude of the BP reduction was independent of BMI. Achievement of target BP (< 140/90 mmHg) was good in all groups, but lower in obese subjects (70.9%) than in overweight subjects (78.1%) or those with a normal BMI (81.8%) (P < 0.0001 for both comparisons).

Conclusions

In subjects with uncontrolled BP on existing antihypertensive therapy, switching to perindopril arginine 10 mg/indapamide 2.5 mg was associated with statistically significant decreases in BP and higher rates of target BP achievement in all BMI groups, including more than 70% of overweight and obese patients.

Non-Adherence to Prescribed Antihypertensives in Primary, Secondary and Tertiary Healthcare Settings in Islamabad, Pakistan: A Cross-Sectional Study

OBJECTIVE

This study aimed to assess the prevalence and predictors of non-adherence to antihypertensive medication among patients with hypertension attending various healthcare settings in Islamabad, Pakistan.

METHODS

A questionnaire-based cross-sectional study was conducted in selected healthcare facilities between September 2017 and December 2018. The study was conducted in primary, secondary and tertiary healthcare settings in Islamabad, Pakistan. Medication adherence was assessed using the eight-item Morisky Medication Adherence Scale (MMAS-8). Sociodemographic and clinical data of recruited patients were collected through a structured questionnaire. Binary logistic regression analysis was performed to determine covariates significantly associated with medication adherence and blood pressure control.

RESULTS

A total of 776 hypertensive patients were invited and 741 (95%) completed the questionnaire. The mean ± SD age of participants was 53.6±12.6 years; 284 patients (38.3%) had high adherence, 178 (24%) had moderate adherence and 279 (37.7%) were non-adherent to the prescribed antihypertensive therapy. Binary regression analysis revealed that old age (OR 1.783 [95% CI: 1.172-2.712]; P=0.013), being educated (OR 2.018 [95% CI: 1.240-3.284]; P=0.036), entitlement to free medical care (OR 1.369 [95% CI: 1.009-1.859]; P=0.044), treatment duration (OR 2.868 [95% CI: 1.913-4.299]; P=0.001), number of medications (OR 1.973 [95% CI: 1.560-2.495]; P=0.001), presence of any comorbidity (OR 2.658 [95% CI: 1.836-3.848]; P=0.001) and blood pressure control (OR 3.103 [95% CI: 2.268-4.247]; P=0.001) were significantly associated with good adherence. Similarly, age (OR 1.998 [95% CI: 1.313-3.040]; P=0.004), entitlement to free medical care (OR 1.498 [95% CI: 1.116-2.010]; P=0.007), treatment duration (OR 1.886 [95% CI: 1.143-3.113]; P=0.013), presence of any comorbidity (OR 1.552 [95% CI: 1.123-2.147]; P=0.008) and adherence level (OR 3.103 [95% CI: 2.268-4.247]; P=0.001) had significant association with controlled blood pressure. The following were the main reasons for non-adherence to prescribed antihypertensive medication: "don't feel need for regular use" (24.7%), "Carelessness" (13.4%) and "adverse effects" (11.2%).

CONCLUSION

The prevalence of non-adherence to antihypertensive medications was high in the study population and poor medication adherence could potentially explain poor blood pressure control. Evidence-based targeted interventions on both medication adherence and blood pressure control should be introduced and implemented for better treatment outcomes.

Adherence to treatment and related factors among patients with chronic conditions in primary care: a cross-sectional study

Background

Adherence to treatment, a public health issue, is of particular importance in chronic disease therapies. Primary care practices offer ideal venues for the effective care and management of these conditions. The aim of this study is to assess adherence to treatment and related-factors among patients with chronic conditions in primary care settings.

Methods

A cross-sectional study was conducted among 299 adult patients with ≥1 chronic condition(s) and prescribed medication in primary healthcare centers of Spain. The Morisky-Green-Levine questionnaire was used to assess medication adherence via face-to-face interviews. Crude and adjusted multivariable logistic regression models were used to analyze factors associated with adherence using the Multidimensional Model proposed by the World Health Organization — social and economic, healthcare team and system-related, condition-related, therapy-related, and patient-related factors.

Results

The proportion of adherent patients to treatment was 55.5%. Older age (adjusted odds ratio 1.31 per 10-year increment, 95% CI 1.01–1.70), lower number of pharmacies used for medication refills (0.65, 95% CI 0.47–0.90), having received complete treatment information (3.89, 95% CI 2.09–7.21), having adequate knowledge about medication regimen (4.17, 95% CI 2.23–7.80), and self-perception of a good quality of life (2.17, 95% CI 1.18–4.02) were independent factors associated with adherence.

Conclusions

Adherence to treatment for chronic conditions remained low in primary care. Optimal achievement of appropriate levels of adherence through tailored multifaceted interventions will require attention to the multidimensional factors found in this study, particularly those related to patients’ education and their information needs.

Self-care research: Where are we now? Where are we going?

BACKGROUND AND OBJECTIVE

The beneficial effects of self-care include improved well-being and lower morbidity, mortality, and healthcare costs. In this article we address the current state of self-care research and propose an agenda for future research based on the inaugural conference of the International Center for Self-Care Research held in Rome, Italy in June 2019. The vision of this Center is a world where self-care is prioritized by individuals, families, and communities and is the first line of approach in every health care encounter. The mission of the Center is to lead the self-care research endeavor, improving conceptual clarity and promoting interdisciplinary work informed by a shared vision addressing knowledge gaps. A focused research agenda can deepen our theoretical understanding of self-care and the mechanisms underlying self-care, which can contribute to the development of effective interventions that improve outcomes.

METHODS

During conference discussions, we identified seven major reasons why self-care is challenging, which can be grouped into the general categories of behavior change and illness related factors. We identified six specific knowledge gaps that, if addressed, may help to address these challenges: the influence of habit formation on behavior change, resilience in the face of stressful life events that interfere with self-care, the influence of culture on self-care behavioral choices, the difficulty performing self-care with multiple chronic conditions, self-care in persons with severe mental illness, and the influence of others (care partners, family, peer supporters, and healthcare professionals) on self-care.

PLANS TO ACHIEVE RESULTS

To achieve the vision and mission of the Center, we will lead a collaborative program of research that addresses self-care knowledge gaps and improves outcomes, create a supportive international network for knowledge transfer and support of innovations in self-care research, and support and train others in self-care research. Beyond these specific short-term goals, important policy implications of this work are discussed.

Self-management and blood pressure control in China: a community-based multicentre cross-sectional study

OBJECTIVES

This study explored the relationship between self-management and blood pressure (BP) control in China.

DESIGN

A cross-sectional study.

SETTING

Eight community health centres from four cities in the Northeast (Shenyang), Northwest (Xi'an), Southwest (Chengdu) and South (Changsha) of China.

PARTICIPANTS

A total of 873 adults with hypertension, including 360 men and 513 women. Hypertension was defined as systolic BP ≥140 mm Hg and/or diastolic BP ≥90 mm Hg.

OUTCOME MEASUREMENTS

BP control was the primary outcome variable. This was categorised as good control if individuals with hypertension reduced their BP to <140/90 mm Hg, otherwise, it was categorised as poor control. Secondary outcomes included self-management, defined as: (1) context or condition-specific factors or physical/social environments (eg, age, sex, marital status, education, personal income and health insurance) and (2) process or knowledge/beliefs, self-regulation skills/abilities and social facilitation (eg, treatment, diet, exercise and risk factor management). Data were analysed using logistic regression models using SPSS V.20.

RESULTS

A total of 67.1% (n=586) participants had poor BP control. Limited outpatient care benefits in mainly rural residents (OR 2.26, 95% CI 1.06 to 4.81) and longer disease duration (OR 1.03, 95% CI 1.01 to 1.04) were associated with poor BP control. Self-management practices reduced the odds of having poor BP control (OR 0.98, 95% CI 0.97 to 0.99).

CONCLUSIONS

The individual and family self-management theory can serve as an effective theory for understanding the key contexts, processes and outcomes essential for BP control in China. Future research should evaluate the effect of a self-management intervention (eg, self-monitoring, medication adherence, regular and routine doctor visits, and social supports) for BP control in China using a multisite cluster randomised controlled trial. Sex and gender difference, cost and patient-reported outcomes should also be examined.

Self-Reported Medication Adherence Measured With Morisky Medication Adherence Scales and Its Determinants in Hypertensive Patients Aged ≥60 Years: A Systematic Review and Meta-Analysis

Background: The aim of this systematic review and meta-analysis was to estimate medication adherence in hypertensive patients aged ≥60 years and to explore potential determinants of adherence with antihypertensive treatment in this age group.

Methods: A systematic search of the PubMed, Scopus, and Google Scholar using the Cochrane guidelines was performed. The analysis included articles published between 1 January 2000 and 30 June 2018. The patients were considered adherent if they scored ≥6 pts. on the Morisky Medication Adherence Scale (MMAS-8) or ≥3 pts. on the Morisky Green Levine Medication Adherence Scale (MGL). If available, also odds ratios (OR) with 95% confidence intervals (95% CI) for determinants of medication adherence were recorded.

Results: Thirteen studies including a total of 5,247 patients were available for the meta-analysis. The pooled percentage of adherence was 68.86% (95% CI: 57.80–79.92%). Subgroup analysis did not demonstrate a significant difference in the adherence measured with the MMAS-8 and the MGL (68.31 vs. 70.39%, P = 0.773). The adherence of patients from Western countries (Europe, United States) turned out to be significantly higher than in other patients (83.87 vs. 54.30%, P = 0.004). The significant determinants of better adherence identified in more than one study were older age, retirement/unemployment, duration of hypertension >10 years, and a lower number of prescribed drugs.

Conclusion: Medication adherence in the oldest old hypertensive patients seems to be higher than in younger persons. Adherence in older persons was associated with age, socioeconomic status, and therapy-related factors.

Mechanisms of vascular comorbidity in autoimmune diseases

Purpose of review

Persuasive statistics support the clinical observation that because of cardiovascular comorbidities patients with inflammatory joint disease die significantly earlier despite anti-inflammatory therapy.

Recent findings

The reason for this earlier death is multifactorial and involves a combination of a complex genetic background, environmental influences, classical cardiovascular risk factors and the impact of anti-inflammatory therapy. We will describe the importance of several new mechanisms, especially the diverse intercellular communication routes including extracellular vesicles and microRNAs that support the development of cardiovascular comorbidities.

Summary

The aim of this review is to give an updated overview about the known risk factors in the development of cardiovascular comorbidities with the latest insights about their mechanism of action. Furthermore, the impact of newly identified risk factors and significance will be discussed.

Novel Medical Treatments for Hypertension and Related Comorbidities

Purpose of Review

The purpose of this review is to summarize the most recent data available on advances in development of novel medical treatments for hypertension and related comorbidities.

Recent Findings

Approximately half of all hypertensive patients have not achieved goal blood pressure with current available antihypertensive medications. Recent landmark studies and new hypertension guidelines have called for stricter blood pressure control, creating a need for better strategies for lowering blood pressure. This has led to a shift in focus, in recent years, to the development of combination pills as a means of achieving improved blood pressure control by increasing adherence to prescribed medications along with further research and development of promising novel drugs based on discovery of new molecular targets such as the counter-regulatory renin-angiotensin system.

Summary

Fixed-dose combination pills and novel treatments based on recently discovered pathogenic mechanisms of hypertension that have demonstrated promising results as treatments for hypertension and related comorbidities will be discussed in this review.

Clinical and Demographic Characteristics Associated With Suboptimal Primary Stroke and Transient Ischemic Attack Prevention: Retrospective Analysis

BACKGROUND AND PURPOSE

Primary prevention of stroke and transient ischemic attack (TIA) is important to reduce the burden of these conditions; however, prescribing of prevention drugs is suboptimal. We aimed to identify individual clinical and demographic characteristics associated with potential missed opportunities for prevention therapy with lipid-lowering, anticoagulant, or antihypertensive drugs before stroke/TIA.

METHODS

We analyzed anonymized electronic primary care records from a UK primary care database that covers 561 family practices. Patients with first-ever stroke/TIA, ≥18 years, with diagnosis between January 1, 2009, and December 31, 2013, were included. Missed opportunities for prevention were defined as people with clinical indications for lipid-lowering, anticoagulant, or antihypertensive drugs but not prescribed these drugs before their stroke/TIA. Mixed-effect logistic regression models evaluated the relationship between missed opportunities and individual clinical/demographic characteristics.

RESULTS

The inclusion criteria were met by 29 043 people with stroke/TIA. Patients with coronary heart disease, chronic kidney disease, peripheral arterial disease, or diabetes mellitus were at less risk of a missed opportunity for prescription of lipid-lowering and antihypertensive drugs. However, patients with a 10-year cardiovascular disease risk ≥20% but without these diagnoses had increased risk of having a missed opportunity for prescription of lipid-lowering drugs or antihypertensive drugs. Women were less likely to be prescribed anticoagulants but more likely to be prescribed antihypertensive drugs. The elderly (≥85 years of age) were less likely to be prescribed all 3 prevention drugs, compared with people aged 75 to 79 years.

CONCLUSIONS

Knowing the patient characteristics predictive of missed opportunities for stroke prevention may help primary care identify and appropriately manage these patients. Improving the management of these groups may reduce their risk and potentially prevent large number of future strokes and TIAs in the population.

Strengthening and implementing health technology assessment and the decision-making process in the Region of the Americas

Objective.

Health technology assessment (HTA) has been adopted by countries in order to improve allocative efficiency in their health systems. This study aimed to describe and analyze the HTA decision-making process in the Region of the Americas.

Methods.

A literature review was done to better understand the HTA situation in the Region. Also, in 2014 and 2015, individuals responsible for conducting HTA in countries of the Americas were identified and received a questionnaire on HTA and the decision-making process.

Results.

A total of 46 questionnaire responses were obtained, from 30 countries. The respondents were similar in terms of their institutions, main funding sources, and technology types assessed. Of the 46 respondents, 23 (50%) work for their respective ministry of health. Also, 36 (78%) undertake and/or coordinate HTA through coverage and reimbursement/pricing decisions and other HTA-related activities, while 24 (52%) use HTA for emerging technologies. While some countries in the Region have created formal HTA units, there is a weak link between the HTA process and decision-making. Most of the countries with recognized HTA institutions are members of the Health Technology Assessment Network of the Americas (RedETSA). Despite the advances in the Region overall, most countries in Central America and the Caribbean are still at the early stages of implementing HTA to support decision-making.

Conclusions.

Many countries in the Americas have benefited from the exchange and capacity-building opportunities within RedETSA. However, there are still many challenges to overcome in the Region in terms of the discussion and creation of HTA-related policies.

Impacts of undetected and inadequately treated hypertension on incident stroke in China

OBJECTIVES

China carries the greatest burden of stroke given its largest volume of people with hypertension. This study assessed the impacts of suboptimal controls of hypertension on incident stroke and projected the number of patients with stroke saved after the control of blood pressure improved in population.

SETTING

Anhui, China.

PARTICIPANTS

We examined data from the Anhui cohort of 2001-2011, consisting of 3336 participants aged ≥60 years who were randomly recruited from the urban and rural Anhui. 2852 participants (89.2%) had hypertensive status measured and no stroke at baseline, and were followed up until 2011 in three surveys using a standard method of interview.

RESULTS

At baseline, 1646 participants (57.7%) were identified to have hypertension, among whom 912 (55.4%) were previously undetected, 115 (7.0%) detected but not treated, 452 (27.5%) treated but not controlled and only 127 (7.7%) controlled. During the 10-year follow-up, 211 incident stroke cases (12.8/1000 person-years) occurred. Compared with normotensive individuals at baseline, multivariate adjusted HR for having stroke increased in those with undetected hypertension by 1.63 (95%CI 1.15 to 2.32), untreated by 2.21 (1.26-3.85) and uncontrolled hypertension by 3.34 (2.28-4.88), but did not differ from those with controlled hypertension (1.34; 0.60-2.99). Based on a two-fold increase in the detection and management of current levels of hypertension and algorithms on the current situation in China, approximately 250 000 incident stroke cases could be prevented annually.

CONCLUSIONS

In China, hypertension is frequently undetected or inadequately treated. With appropriate management of hypertension, a substantial number of people could be saved form stroke.

Risk Factors for Chronic Diseases and Multimorbidity in a Primary Care Context of Central Argentina: A Web-Based Interactive and Cross-Sectional Study

Global health agencies estimate an increase of chronic diseases in South America. Nevertheless, few studies have investigated chronic diseases and their risk factors in the perspective of multimorbidity. This research aimed to identify these aspects in a primary health care setting of central Argentina. The Pan America version of the STEP wise approach surveillance (STEPS) instrument of the World Health Organization was applied to 1044 participants, 365 men and 679 women, with a mean age of 43 years. High prevalence of overweight (33.5%), obesity (35.2%), central obesity (54%), dyslipidemia (43.5%), metabolic syndrome (21.1%), low intake of fruit and vegetables (91.8%), low levels of physical activity (71.5%), risky alcohol consumption (28%), and smoking (22.5%) were detected. Hypertension and diabetes were the most prevalent chronic conditions and the total prevalence of multimorbidity was 33.1%, with 2, 3, 4, 5 and 6 chronic conditions found in 19.9%, 9.1%, 2.6%, 1.1% and 0.4% of the population, respectively. Multimorbidity affected 6.4% of the young, 31.7% of the adults, and 60.6% of the elderly, and was more prevalent among women, and in participants with lower levels of education. Having multimorbidity was significantly associated with obesity, central obesity, and higher concentrations of total blood cholesterol, low-density lipoprotein cholesterol, triglycerides, and glucose. A website was made available to the participants in order to share the experimental results and health-promoting information.
