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

Treatment adherence and the contemporary approach to treating type 2 diabetes mellitus

The rising burden of type 2 diabetes mellitus (T2D) poses a significant healthcare challenge on a global scale. The economic impact is also substantial and continually increasing. In Serbia, even though the prevalence is officially around 12 percent, nearly 40 percent of the adult population is estimated to be living with undiagnosed diabetes and more than half the population is obese or overweight. This review comprehensively addresses the present approach to treating T2D, emphasizing the critical role of treatment adherence. We review the various components of T2D treatment, underlining the significance of lifestyle modifications. The pros and cons of medications used in treatment are discussed and factors influencing adherence are analysed. A healthy lifestyle remains the foundation of the treatment, and if not sufficient, early pharmacotherapy is initiated. Medications have been developed to lower blood sugar levels with cardiorenal protection, however, due to their still high cost, metformin remains the drug of first choice for most patients. Adherence to the treatment regimen is often poor. Factors associated with this are diverse and often multiple in a particular patient. Poor adherence is associated with poor glycaemic control, increased risk of disease complications, higher cardiovascular risk, increased mortality, hospitalizations, and healthcare costs. In addition to reducing the complexity of drug therapy and better informing the patient, improved education and motivation could lead to greater adherence. Enhanced communication between the patient and the physician and reduced treatment costs could also have a positive impact. The review concludes that addressing factors affecting adherence can significantly improve T2D outcomes and reduce costs. Further research is needed to identify region-specific risk factors for poor adherence.

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.

Factors Influencing Medication Adherence Among Adults Living with Diabetes and Comorbidities: a Qualitative Systematic Review

PURPOSE OF REVIEW

Medication adherence plays an important role in improving health outcomes related to diabetes and comorbidity. The potential factors influencing medication adherence and how they contribute to health behaviors have not been synthesized to date. This review synthesized qualitative studies that identified factors influencing medication adherence among adults living with diabetes and comorbidity.

RECENT FINDINGS

Twenty-eight findings were extracted and synthesized into four themes: perceived support, lack of knowledge, medication issues, and the importance of routine. The findings highlight the factors that support medication adherence and areas that can be targeted to support and promote medication adherence. The findings also support the potential role of healthcare providers in supporting people living with diabetes and comorbidity to adhere to and maintain medication regimes. Several factors were identified that are amenable to intervention within the clinical practice setting and have the potential to enhance medication adherence and improve health outcomes for people living with diabetes and comorbidities. The development of acceptable and effective interventions could have a positive effect on medication adherence and health outcomes.

Adherence to pharmacological treatment in non-communicable chronic diseases in the Colombian population: Systematic review and meta-analysis

Introduction. Non-communicable chronic diseases represent the leading cause of death worldwide, and their prevalence is increasing due to the epidemiological transition. Despite the advances in their management, control rates are deficient, attributed to multiple factors like adherence to pharmacological treatment, one of the most significant and least studied in the Colombian population. Objective. To calculate adherence to treatment in Colombian patients with arterial hypertension, cerebrovascular disease, diabetes mellitus, asthma, chronic obstructive pulmonary disease, and dyslipidemia between 2005 and 2022. Materials and methods. We performed a systematic literature review and a meta-analysis of studies identified through the Medline and LILACS databases to quantitatively synthesize treatment adherence percentage. Results. Fourteen studies met the inclusion criteria, and 5,658 patients were analyzed. The treatment adherence was 59%, with significant heterogeneity among the included studies (95% CI= 46- 71%; I2 = 98.8%, p< 0.001). Higher adherence rates were observed for diabetes mellitus (79%; 95% CI = 65- 90%) and dyslipidemia (70%; 95% CI = 66- 74%). Adherence to arterial hypertension treatment was 51% (95 %; CI = 31- 72%). Conclusions. This systematic review showed low adherence to recommendations regarding pharmacological management in non-communicable chronic diseases, which can have implications for long-term clinical outcomes and disease burden.
