Comparison of medication adherence between type 2 diabetes mellitus patients who pay for their medications and those who receive it free: a rural Asian experience

Insulin Adherence in Adolescents with Type 1 Diabetes Mellitus

Adherence to medication, especially insulin, is a key contributor to diabetes treatment outcomes. Lack of adherence is common among patients with type 1 diabetes mellitus (T1DM) ranging from 23% to 77%, with a higher frequency in developing countries. Poor adherence results in worse glycaemic control and increased mortality and morbidity due to diabetes complications. The objective of this study is to discuss insulin adherence among adolescents with T1DM. The review was conducted through search engines such as PubMed, Medline, Embase and Google Scholar. Search terms used were 'type 1diabetes mellitus', 'insulin dependent diabetes mellitus', 'Juvenile diabetes mellitus', 'adherence', 'compliance', 'non adherence', 'barriers', 'omission', 'medical adherence', 'adolescents', 'teenagers' and 'insulin'. T1DM is challenging for adolescents due to its lifelong treatment regimens. Educational programmes and specific interventions which can improve affordability, accessibility and administration of insulin should be implemented to improve insulin adherence among adolescents.

Effectiveness of educational intervention in improving medication adherence among patients with diabetes in Klang Valley, Malaysia

Background

The diabetes patients’ adherence to prescription medication is 67.5%, which is lower than that of patients with any other medical conditions. Patients with low medication adherence are more likely to experience clinical complications, repeated hospitalizations, increased mortality, and increased healthcare costs, hence, education on disease and medication adherence is vital now. This study aimed to assess the level of medication adherence, medicine and information-seeking behaviour, and the effectiveness of online educational intervention in improving medication adherence and medicine and information-seeking behaviours among patients with diabetes in Klang Valley, Malaysia.

Methods

Individuals aged 12 years and above with a prior diagnosis of diabetes were identified and randomly divided into (control (n=183), and intervention groups (n = 206). Data about their medication adherence and information-seeking behaviour were obtained. As part of the online educational intervention, a month of daily general reminders to take their medications and educational materials about diabetes had provided to them via WhatsApp groups. After a month, the groups were reassessed, and the data were compared.

Results

The results showed that, at baseline, most of the respondents in the control (58.8% females and 53.08% males) and intervention (65.52% females and 85.12% males) groups had a low level of medication adherence. After a month of intervention, medication adherence was significantly improved in the intervention group (91.4% females and 71.28% males) compared to the control group (38.23% females and 44.44% males). At baseline, only 96 (52.45%) respondents in the control group and 110 (52.38%) in the intervention group preferred to read online educational materials to know more about their condition(s), it was improved after a month of intervention in the intervention group where 204 (99.02%) respondents prefer online materials, however no change in the control group response.

Conclusion

The study concludes that medication adherence and information-seeking behaviours among the study population have been significantly improved after a month of structured intervention. Medication adherence plays a crucial role in risk reduction strategies subsequently it improves the patient’s quality of life. Thus, well-planned more robust educational interventions on chronic diseases are warranted to improve the health outcomes of the patients.

Adherence to Oral Antidiabetic Drugs in Patients with Type 2 Diabetes: Systematic Review and Meta-Analysis

Poor adherence to oral antidiabetic drugs (OADs) in patients with type 2 diabetes (T2D) can lead to therapy failure and risk of complications. The aim of this study was to produce an adherence proportion to OADs and estimate the association between good adherence and good glycemic control in patients with T2D. We searched in MEDLINE, Scopus, and CENTRAL databases to find observational studies on therapeutic adherence in OAD users. We calculated the proportion of adherent patients to the total number of participants for each study and pooled study-specific adherence proportions using random effect models with Freeman-Tukey transformation. We also calculated the odds ratio (OR) of having good glycemic control and good adherence and pooled study-specific OR with the generic inverse variance method. A total of 156 studies (10,041,928 patients) were included in the systematic review and meta-analysis. The pooled proportion of adherent patients was 54% (95% confidence interval, CI: 51-58%). We observed a significant association between good glycemic control and good adherence (OR: 1.33; 95% CI: 1.17-1.51). This study demonstrated that adherence to OADs in patients with T2D is sub-optimal. Improving therapeutic adherence through health-promoting programs and prescription of personalized therapies could be an effective strategy to reduce the risk of complications.

Factors Contributing to Noncompliance With Diabetic Medications and Lifestyle Modifications in Patients With Type 2 Diabetes Mellitus in the Eastern Province of Saudi Arabia: A Cross-Sectional Study

BACKGROUND

Type 2 diabetes mellitus (T2DM) is defined as a chronic medical condition in which the blood glucose level remains high. The risk factors of T2DM are high body mass index due to obesity or being overweight, genetics, and certain medical conditions. Lifestyle modification plays a crucial role in T2DM regulation and prevention, and if it is not controlled well by either lifestyle modification or DM regulatory medications, it may lead to medical complications ranging from mild to life-threatening complications.

AIM

The purpose of this study is to find the contributory factors of noncompliance with oral antidiabetic drugs and lifestyle modifications in patients with T2DM in the eastern province of Saudi Arabia. This will help control one of the most widespread comorbidities that might otherwise be a significant burden on patients' health and financial status as well as on the government.

METHODOLOGY

A cross-sectional questionnaire study was conducted on T2DM patients in the eastern province of Saudi Arabia through a link distributed on social media, and the contributory factors of noncompliance to diabetes medication and lifestyle modification were evaluated.

RESULTS

A total of 426 participants were included in the study. Regarding compliance with DM medications, 199 (46.7%) participants were adherent to their medications, 148 (34.7%) were not adherent to their medication, 42 (9.9%) were sometimes adherent, and 37 (8.7%) were mostly adherent to their medication. Regarding lifestyle modification, the level of adherence to a healthy diet and exercise among T2DM patients in the eastern province was low and unsatisfactory. According to the participants, the most reported factors contributing to noncompliance with DM medications and lifestyle modifications were forgetfulness, lack of knowledge about diabetes and the importance of controlling it, side effects of the medications, and difficulty in following a healthy diet. Regarding the influence of sociodemographic variables on the level of adherence in T2DM patients, factors such as age, marital status, occupation, comorbidities, diagnosis period, and previous complaints of DM complications showed significant associations with compliance with DM medication.

CONCLUSION

The findings of this study revealed that the level of adherence to DM medications among T2DM patients in the eastern province was suboptimal. Although free medicines were available with a high level of healthcare access through government primary healthcare centers (PHCCs), poor adherence was observed. This study highlighted that medication adherence might be affected by age, marital status, occupation, chronic diseases, diagnosis period, and previous complaints of DM complications. Regarding lifestyle modification, this study showed that the level of adherence to a healthy diet and exercise among T2DM patients in the eastern province was low and unsatisfactory. Our recommendation is to measure the presence of dietician clinics, patient relationships with their healthcare providers, and their effect on patient compliance with DM medications. Further research is needed to include other factors that could influence adherence, such as patient-healthcare provider communication. Moreover, it is suggested that PHCCs discuss with noncompliant patients the reasons that prevent them from adhering to their medication and lifestyle modifications as part of their care plan.

Self-care behaviours among people with type 2 diabetes mellitus in South Asia: A systematic review and meta-analysis

Background

The burden of Type 2 Diabetes Mellitus (T2DM) in South Asian countries is increasing rapidly. Self-care behaviour plays a vital role in managing T2DM and preventing complications. Research on self-care behaviours among people with T2DM has been widely conducted in South Asian countries, but there are no systematic reviews that assess self-care behaviour among people with T2DM in South Asia. This study systematically assessed the studies reporting self-care behaviours among people with T2DM in South-Asia.

Methods

Adhering to the PRISMA guidelines, we searched six bibliographic databases (Scopus, PubMed, CINAHL, Embase, Web of Science, and PsychInfo) to identify the relevant articles published between January 2000 through March 2022. Eligibility criteria included all observational and cross-sectional studies reporting on the prevalence of self-care behaviours (ie, diet, physical activity, medication adherence, blood glucose monitoring, and foot care) conducted in South Asian countries among people with T2DM.

Results

The database search returned 1567 articles. After deduplication (n = 758) and review of full-text articles (n = 192), 92 studies met inclusion criteria and were included. Forward and backward reference checks were performed on included studies, which resulted in an additional 18 articles. The pooled prevalence of adherence to blood glucose monitoring was 65% (95% CI = 49-80); 64% for medication adherence (95% CI = 53-74); 53% for physical activity (95% CI = 39-66); 48% for diet (95% CI = 38-58); 42% for foot care (95% CI = 30-54). About a quarter of people with T2DM consumed alcohol (25.2%, IQR = 13.8%-38.1%) and were using tobacco products (18.6%, IQR = 10.6%-23.8%).

Conclusions

Our findings suggest that the prevalence of self-care behaviours among people with T2DM in South Asia is low. This shows an urgent need to thoroughly investigate the barriers to the practising of self-care and design and implement interventions to improve diabetes self-care behaviour among people with T2DM in South Asia.

Exploring of Determinants Factors of Anti-Diabetic Medication Adherence in Several Regions of Asia - A Systematic Review

BACKGROUND

The determinants of medication adherence in people with diabetes may differ between populations of an area due to social environment, cultural beliefs, socioeconomic conditions, education, and many other factors differences.

OBJECTIVE

Therefore, this study aims to explore, identify and classify the determinants of medication adherence in several Asian regions.

METHODS

A systematic literature review was conducted to gain insight into the determinants of medication adherence. Seven relevant databases (EBSCO, ProQuest, PubMed, ScienceDirect, Scopus, Wiley, dan Taylor and Francis) and hand searching methods were conducted from January 2011 to December 2020. Keywords were compiled based on the PICO method. The selection process used the PRISMA guidelines based on inclusion, and the quality was assessed using Crowe's critical assessment tool. Textual summaries and a conceptual framework model of medication adherence were proposed to aid in the understanding of the factors influencing medication adherence.

RESULTS

Twenty-six articles from countries in several Asian regions were further analyzed. Most studies on type 2 diabetes patients in India used the MMAS-8 scale, and cross-sectional study is the most frequently used research design. The medication adherence rate among diabetic patients was low to moderate. Fifty-one specific factors identified were further categorized into twenty-three subdomains and six domains. Furthermore, the determinants were classified into four categories: inconsistent factors, positively related factors, negatively related factors, and non-associated factors. In most studies, patient-related factors dominate the association with medication adherence. This domain relates to patient-specific demographics, physiological feelings, knowledge, perceptions and beliefs, comorbidities, and other factors related to the patient. Several limitations in this review need to be considered for further research.

CONCLUSION

Medication adherence to diabetic therapy is a complex phenomenon. Most determinants produced disparate findings in terms of statistical significance. The identified factors can serve various goals related to medication adherence. Policymakers and health care providers should consider patient-related factors.

Magnitude and associated factors of poor medication adherence among diabetic and hypertensive patients visiting public health facilities in Ethiopia during the COVID-19 pandemic

Objective

This study aims to assess the magnitude and associated factors of poor medication adherence among diabetic and hypertensive patients visiting public health facilities in Addis Ababa, Ethiopia during the COVID-19 pandemic.

Methods

A multi-site cross-sectional design was conducted from 1^st through 30^th of August 2020 at public health facilities of the study area. Adult outpatients with T2DM and hypertension visiting hospitals and health centers were included in the study. A proportion to size allocation method was used to determine the required sample size per facility. Data was collected using the 8-item Morisky medication adherence scale. Descriptive statistics and binary logistic regression were used to analyze data. A 95% confidence interval and p≤0.05 statistical significance was considered to determine factors associated with poor medication adherence.

Results

A total of 409 patients were included in the present study. About 57% of the patients reported that the COVID-19 pandemic has posed negative impacts on either of their follow-up visits, availability of medications, or affordability of prices. And, 21% have reported that they have been affected in all aspects. The overall magnitude of poor medication adherence was 72%. Patients with extreme poverty were more likely to have good medication adherence (AOR: 0.59; 95%C.I: 0.36–0.97), whereas attendance to a health center (AOR: 1.71; 95%C.I: 1.02–2.85), presence of comorbidity (AOR: 2.05; 95%C.I: 1.13–3.71), and current substance use history (AOR: 11.57; 95%C.I: 1.52–88.05) predicted high odds of poor adherence.

Conclusion

Over a three-fourth of the patients, in the study setting, have poor adherence to their anti-diabetic and antihypertensive medications. Health facility type, income level, comorbidity, and current substance use history showed a statistically significant association with poor adherence to medication. Stakeholders should set alternative strategies as perceived impacts of the COVID-19 pandemic on medication adherence are high in the study area.

Appropriateness and affordability of prescriptions to diabetic patients attending a tertiary hospital in Eastern Uganda: A retrospective cross-sectional study

Background

Irrational prescription of drugs can lead to high cost of treatment thus limiting access to essential medicines. We assessed the affordability and appropriateness of prescriptions written for diabetic patients in Eastern Uganda.

Methods

We collected secondary data from the health management information system registers of patients who attended the outpatient medical clinic at Mbale regional referral hospital from January 2019 to December 2019. The average cost of the prescriptions was calculated and adjusted odds ratios for predictors for unaffordability estimated using logistic regression. Computed scores for indicators of rational drug prescription were used to assess the extent of rational prescribing.

Results

The median cost per prescription was USD 11.34 (IQR 8.1, 20.2). Majority of the diabetic patients (n = 2462; 94.3%, 95% CI: 93.3–95.1%) could not afford the prescribed drugs. Predictors for unaffordability were if a prescription contained: ≥ 4 medicines (AOR = 12.45; 95% CI: 3.9–39.7); an injectable (AOR = 5.47; 95%CI: 1.47–20.32) and a diagnosis of diabetes mellitus with other comorbidities (AOR = 3.36; 95%CI: 1.95–5.78). Having no antidiabetic drug prescribed was protective for non-affordability (AOR = 0.38; 95%CI: 0.24–0.61). The average number of drugs per prescription was 2.8. The percentage prescription of drugs by generic name and from the essential medicine and health supplies list of Uganda were (6160/7461; 82.6%, 96% CI: 81.7%-83.4%) and (6092/7461; 81.7%, 95% CI: 80.8%-82.5%) respectively against WHO standard of 100%.

Conclusion

The majority of diabetic patients (94.3%) in Eastern Uganda cannot afford to buy prescribed medicines. The government should therefore ensure that essential medicines are readily accessible in public health facilities.

Determinants of Non-Adherence to Treatment Among Patients with Type 2 Diabetes in Kenya: A Systematic Review

INTRODUCTION

Non-adherence to the prescribed treatment regimen in patients with type 2 diabetes mellitus is quite high. Furthermore, it has been associated with higher rates of hospital admissions, suboptimal health outcomes, increased morbidity and mortality, and increased health care costs. The present systematic review study aimed to explore the determinants that contribute to non-adherence to treatment among patients with type 2 diabetes mellitus in Kenya.

METHODS

A systematic review of studies conducted in Kenya on the present research problem published in English between December 2013 and May 2020. The databases included Scopus, Web of Science, Science Direct, Cochrane Library, PUBMED, OVID and Google Scholar. The following were the key words used in the search: "Non-adherence Diabetes Patients", "Determinants of Non-adherence Diabetes Patients" AND "Health Facilities" AND "Kenya". Qualitative analysis was used to present data under thematic domains.

RESULTS

The search generated 17,094 articles of which only 15 met the inclusion criteria. The major determinants were presented under three thematic domains: 1) Cost - income, insurance, distance, bills of drugs and food; 2) Patient characteristics - perception of (efficacy, severity, effects of non-adherence), knowledge, co-morbidity, family support, self unfounded beliefs; and 3) Health system - health education, multiple drugs, evaluations and support, guidelines, poor perception of system.

CONCLUSION

A multitude of factors including unaffordable care, patient's poor knowledge on the disease process, less family support in patient's daily self-care management, complex drug regimen and unsatisfactory health messages from the health providers were observed to be associated with non-adherence. Implementing integrated care programs will help in reducing levels of non-adherence among type 2 diabetes mellitus patients.

Clinicians' Values and Preferences for Medication Adherence and Cost Clinical Decision Support in Primary Care: A Qualitative Study

BACKGROUND

Medication nonadherence and unaffordability are prevalent, burdensome issues in primary care. In response, technology companies are capitalizing on clinical decision support (CDS) to deliver patient-specific information regarding medication adherence and costs to clinicians using electronic health records (EHRs). To maximize adoption and usability, these CDS tools should be designed with consideration of end users' values and preferences.

OBJECTIVE

This article evaluates primary care clinicians' values and preferences for a medication adherence and cost CDS.

METHODS

We conducted semistructured interviews with primary care clinicians with prescribing privileges and EHR access to identify clinicians' perceptions of and approaches to assessing medication adherence and costs, and to determine perceived values and preferences for medication adherence and cost CDS. Interviews were conducted until saturation of responses was reached. ATLAS.ti was used for thematic analysis.

RESULTS

Among 26 clinicians interviewed, themes identified included a high value, but moderate need for a medication adherence CDS and high value and need for cost CDS. Clinicians expressed the cost CDS would provide actionable solutions and greatly impact patient care. Another theme identified was a desire for medication adherence and cost CDS to be separate tools yet integrated into workflow. The majority of clinicians preferred a medication adherence CDS that integrated claims data and actively displayed data using color-coded adherence categories within patients' medication lists in the EHR. For the cost CDS, clinicians preferred medication out-of-pocket costs and a list of cheaper or payor-preferred alternatives to display within the order queue of the EHR.

CONCLUSION

We identified valuable insights regarding clinician values and preferences for medication adherence and cost CDS. Overall, primary care clinicians feel CDS for medication adherence and cost are valuable and prefer them to be separate. These insights should be used to inform the design, implementation, and EHR integration of future medication and cost CDS tools.

Medication adherence and glycemic control among diabetes patients in developing countries

The potential interconnectedness of medication adherence, glycemic control, and clinical inertia in resource-constrained settings of the developing world needs further evaluation.
