Medicated-related burden and adherence in patients with co-morbid type 2 diabetes mellitus and hypertension

High Burden and Trend in Nonadherence to Blood Pressure-Lowering Medications: Meta-Analysis of Data From Over 34 000 Adults With Hypertension in Sub-Saharan Africa

BACKGROUND

Nonadherence to blood pressure (BP)-lowering medication is a strong predictor of poor BP control. Sub-Saharan Africa has extremely low BP control rates (~10%), but it is unclear what the burden of medication nonadherence among Africans with hypertension is. This systematic review estimated the prevalence and determinants of nonadherence to BP-lowering medications in Sub-Saharan Africa.

METHODS AND RESULTS

Multiple databases were searched from inception to December 6, 2023. Two reviewers performed independent screening, extraction, and quality assessment of studies. We pooled the prevalence estimates using random effects meta-analyses and summarized the determinants using a narrative synthesis. From the 1307 records identified, we included 95 studies published between 1995 and 2023. The overall prevalence of nonadherence to BP-lowering medication among 34 102 people treated for hypertension in 27 countries was 43.9% (95% CI, 39.2-48.6). There was no change in the prevalence of nonadherence over time. Nonadherence varied by measurement method and by median age (39.4%, ≥57 years versus 47.9%, <57 years). Socioeconomic and patient-related factors were the most frequent factors influencing adherence. Active patient participation in management, accurate perceptions, and knowledge of hypertension and its treatment predicted good medication adherence, whereas high pill burden, medication cost, side effects, and comorbidities predicted poor adherence.

CONCLUSIONS

Two out of every 5 people are nonadherent to their BP treatment. With the African population projected to increase from 1.4 to ~2.5 billion by 2050, targeted strategies are urgently needed to optimize medication adherence in people with hypertension in Sub-Saharan Africa.

Diabetes Educators: Understanding the Role of Finerenone in Chronic Kidney Disease Associated with Type 2 Diabetes Mellitus

People living with type 2 diabetes mellitus (T2DM) are at risk of developing diabetes-related complications such as chronic kidney disease (CKD). Screening for CKD is considered the standard of diabetes care, but less than half of people living with diabetes in the United States receive guideline-directed kidney disease testing. Despite recent pharmacologic advances for the treatment of this condition, insufficient screening delays both diagnosis and treatment of diabetes-related CKD and increases the risk of poor outcomes. The nonsteroidal mineralocorticoid receptor antagonist finerenone is an orally administered drug that, when taken with the maximum tolerated dose of a renin-angiotensin-aldosterone system inhibitor, can provide kidney and cardiovascular benefits for people living with T2DM-related CKD. Yet, uptake of this drug has been slow. Increasing awareness of finerenone may encourage its use in clinical practice. Diabetes educators are healthcare professionals (HCPs) with extensive diabetes care experience who encourage diabetes self-management and provide patients with education on the prevention of diabetes-related complications. Diabetes educators bridge knowledge and care gaps among other HCPs by facilitating communication between members of the care team and raising awareness on the importance of CKD prevention and screening. Additionally, diabetes educators reinforce the clinical evidence behind available treatments to promote adherence to guidelines. Here, the evidence for finerenone in T2DM-related CKD and the role of the diabetes educator from both patient and HCP perspectives are reviewed.Graphical abstract available for this article.

A scoping review of interventions to optimize medication adherence in hypertension comorbidity

BACKGROUND

Patients with hypertension and other comorbidities have difficulties adhering to their medications which have negative impacts on clinical outcomes. Although some studies have identified strategies to improve medication adherence, a thorough analysis of these interventions will provide synthesized evidence for clinical decision-making and improved health outcomes for patients with hypertension comorbidities.

AIM

To conduct a scoping review on interventions that have been utilised to improve medication adherence in patients with hypertension and other co-morbid conditions.

METHODS

A systematic literature search was conducted in the following databases: CINAHL, COCHRANE TRIALS, MEDLINE, and SCOPUS. One (1) search engine, GOOGLE SCHOLAR was included. This was done between September 2023 to February 2024. The PRISMA-SCR guidelines were followed for this review. A total of 456 unique studies were identified after duplicates were removed. Following screening and eligibility assessments, 26 papers were selected for review with a focus on the study aim and purpose, study population, interventions used and adherence measures.

RESULTS

Most of the interventions were delivered by pharmacists, with 25 studies utilising the multimodal intervention approach. A total of 22 studies (80 % of the total) found that the interventions significantly improved medication adherence. Results from 16 studies showed a significant improvement in blood pressure. Improvements in medication adherence were a common outcome of interventions that focused on patient education.

CONCLUSION

Interventions such as patient education, simplified treatment regimens, and multidisciplinary care can improve medication adherence and clinical outcomes in patients with hypertension and comorbidities, but further research is needed to understand long-term effects.

Prevalence of Hypertension and Its Clinical and Psychological Factors in Type 2 Diabetes Patients in Ghana: A Secondary Analysis of a Cross-Sectional Study

Background: Hypertension (HTN) is common in patients with type 2 diabetes mellitus (T2DM). Patients with both T2DM and HTN have a higher risk of heart disease, kidney disorders, and mortality than those with either HTN or T2DM alone. Patients' psychological well-being plays a significant role in the optimum management of these chronic conditions. This study is aimed at determining the current prevalence of HTN and its related clinical and psychological factors in patients with T2DM. Methods: This cross-sectional study was conducted at the Korle-Bu Teaching Hospital with 156 patients diagnosed with T2DM. A structured questionnaire was used to obtain information on sociodemographic and clinical characteristics. In addition, the following information was obtained from the patients' clinical files: blood pressure, height, weight, waist circumference, serum creatinine, and urine protein. Depression, resilience, and coping skills of the participants were measured using the Brief Symptom Inventory-18, Resilience Scale for Adults, and Brief COPE Inventory, respectively. Data were analyzed using STATA version 18, with a significance level of p < 0.05. Results: The median age of respondents was 62.0 (IQR: 51.50, 67.00) years. The majority was female (76.3%). The prevalence of HTN among the patients with T2DM was 79.9% (95% CI: 72.7-85.9). The average body mass index (BMI) of the patients was 28871kg/m2 with 34.8% and 36.2% being overweight and obese, respectively. The average HBA1C level was 8.6 ± 2.1 with 71.8% of the patients having poor glycemic control. Increasing age, caregiver, and personal resilience were factors significantly associated with HTN (p value of <0.05) among patients with T2DM. Conclusion: The prevalence of HTN among T2DM patients was high; age, caregiver, and personal resilience significantly predicted HTN among T2DM patients. These findings have implications for healthcare providers in implementing strategies to reduce central obesity and incorporating resilience as an important factor in improving treatment outcomes in patients with T2DM.

The Impact of Medication Regimen Adjustment Ratio on Adherence and Glycemic Control in Patients with Type 2 Diabetes and Mild Cognitive Impairment

BACKGROUND

An antidiabetic medication regimen is crucial for maintaining glycemic control. Type 2 diabetes mellitus (T2DM) and cognitive dysfunction have a bidirectional relationship. This study aims to explore the impact that adjusting antidiabetic medication regimens has on medication adherence, glycemic control, and cognitive function in patients with T2DM and mild cognitive impairment (MCI).

METHODS

This is an observational cross-sectional analysis that includes 364 consecutive inpatients with T2DM. Clinical data were collected, medication adherence was assessed using the Medication Adherence Report Scale (MARS-5), and cognitive status was evaluated using the Chinese version of the Montreal Cognitive Assessment (MoCA) and Mini-mental State Examination (MMSE). These data were obtained both during hospitalization and at a three-month follow-up. Multivariable logistic regression analysis was applied to determine the association between changes in medication regimens and medication adherence, glycemic control, and cognitive function.

RESULTS

Baseline medication adherence was high across all three different cognitive status groups, with no significant difference in MARS-5 scores. At the 3-month follow-up, the group with a high adjustment ratio of antidiabetic medication regimens showed an increase in their hemoglobin A1c (HbA1c) level compared to the baseline, while the group with a low adjustment ratio showed a decrease in this level. In addition, the MoCA, MMSE, and MARS-5 scores of the high-adjustment group were significantly lower than those of the low-adjustment group.

CONCLUSIONS

A high ratio of medication adjustment was significantly associated with worse medication adherence and glycemic control in T2DM patients with MCI. Patients with a low ratio of medication adjustment had good adherence and better glycemic control. Clinicians should take cognitive status into account when adjusting antidiabetic regimens for T2DM patients and may need to provide additional guidance to patients with cognitive impairment to improve adherence and glycemic outcomes.

Determinants Affecting the Awareness of Hypertension Complications within the General Population in Saudi Arabia

BACKGROUND

Hypertension imposes a significant public health burden. An increased awareness of hypertension complications within a population can positively impact patient care and prevent complications. This study seeks to assess the awareness of hypertension complications among the population of Bisha in Saudi Arabia in 2020.

METHODS

A cross-sectional study was conducted in 2020. A validated self-administered online-based questionnaire was sent to a sample of the adult population of Bisha to measure their awareness of hypertension complications.

RESULTS

Almost three-quarters of the population (72.2%) were aware of hypertension complications. The awareness level was significantly higher among male participants (p < 0.001), those aged 31-40 years, those who were married, those working as police officers or in civilian jobs, those living in urban areas (p = 0.04), those with a university-level education (p = 0.03), those with a medium family income (SAR 5000-14,999) (p = 0.001), and those with a history of hospitalization because of causes other than hypertension (p = 0.05). Marital status was independently predictive of awareness (B = 0.851, Wald test = 12.179, p = 0.000) among the respondents.

CONCLUSION

The study concludes that the awareness of hypertension complications among the Bisha population in Saudi Arabia was deemed acceptable. Factors such as marital status, age, gender, a family history of hypertension, the duration of hypertension, and medication adherence positively influenced this awareness and served as predictors of hypertensive awareness. The findings highlight the importance of health authorities in ensuring the widespread awareness of hypertension complications, particularly among hypertensive individuals.

Treatment burden and regimen fatigue among patients with HIV and diabetes attending clinics of Tikur Anbessa specialized hospital

Nascent studies showed that patients with chronic medical illnesses such as diabetes mellitus (DM) and HIV/AIDS are highly vulnerable to face both treatment burden and regimen fatigue. However, an attempt made so far in this sphere in sub-Saharan African health care context is dearth. Thus, this study aimed to determine the level of treatment burden and regimen fatigue of diabetic and HIV patients attending adult diabetic and ART clinics of TASH and explore patients' and health care workers' propositions to reduce treatment burden and regimen fatigue. An explanatory sequential mixed methods study was conducted at the adult HIV and DM clinics of TASH, Addis Ababa, Ethiopia from February 01-March 30, 2022. Simple random and purposive sampling techniques were employed to select participants for quantitative and qualitative studies, respectively. Descriptive analysis was done to summarize the quantitative data. Logistic and linear regression analyses were performed to identify predictors of treatment burden and regimen fatigue, respectively. P value < 0.05 was considered statistically significant. Qualitative data was analyzed by using a thematic analysis. A total of 300 patients (200 diabetes and 100 HIV) were included in the quantitative study. For the qualitative study, 14 patients and 10 health care workers (six nurses and four medical doctors) were included. Participants' mean global Treatment Burden Questionnaire (TBQ) and Treatment Regimen Fatigue Scale (TRFS) score were 28.86 ± 22.13 and - 42.82 ± 17.45, respectively. Roughly, 12% of patients experienced a high treatment burden. The presence of two or more comorbidities (adjusted odds ratio [AOR] = 7.95, 95% confidence interval [CI] 1.59-39.08), daily ingestion of more than five types of prescribed medications (AOR = 6.81, 95%CI 1.59-29.14), and good knowledge about DM and/or HIV (AOR = 0.33, 95%CI 0.12-0.92) were predictors of treatment burden. Poor availability of medications (β = 0.951, p < 0.001) was the only predictor of regimen fatigue. Patients and health care workers primarily proposed to foster self-care efficacy, advance administrative services of the clinic and hospital, and improve healthcare system provision. The findings of this study unveiled that a considerable proportion of patients experienced low levels of treatment burden and regimen fatigue. This study showed that boosting the patients' self-care efficacy, upgrading administrative services of the clinic and hospital, and promoting the healthcare system provision had enormous significance in reducing treatment burden and regimen fatigue. Therefore, when designing patient-specific healthcare interventions for both HIV and diabetic patients' various factors affecting both treatment burden and regimen fatigue should be considered to achieve the desired goals of therapy.

Factors influencing medication adherence in co-morbid hypertension and diabetes patients: A scoping review

Introduction

Interest in medication adherence has expanded significantly, especially in relation to the management of hypertension or diabetes in recent years. A scoping review that focuses on medication adherence in the co-morbidity of hypertension and diabetes provides crucial guidance for effective management of these interrelated diseases.

Aim

To conduct a scoping review of factors associated with medication adherence among individuals with co-morbid hypertension and diabetes.

Methods

The evaluation was conducted in accordance with the PRISMA-ScR guidelines to ensure the quality of the study. We searched three databases (Scopus, CINAHL, Medline) and one search engine (Google Scholar) from April 2023 to July 2023 on studies related to medication adherence in co-morbid hypertension and diabetes. Except for reviews there were no restrictions on design, location, and time of study.

Results

In total, 972 studies that were not duplicated were obtained. After eligibility and screening procedures were completed, 31 articles were ultimately included in the scoping review. Medication adherence was significantly affected by patient, condition, therapy, socio-economic and health related factors. Intervention trials revealed that education and counselling by pharmacists, nurses, physicians, diabetes educators, community health workers and the use of telephone to motivate patients significantly improved medication adherence.

Conclusion

This review shows the intricate factors influencing medication adherence in patients with co-morbid hypertension and diabetes, emphasizing the need for tailored interventions involving healthcare professionals, policymakers, and researchers.
