Summary
This study analyzed shared decision-making (SDM) research in type 2 diabetes mellitus (T2DM). Findings show growing research primarily from the Global North, highlighting a need for broader global collaboration in diabetes care.
Area of Science:
- Bibliometrics
- Health Services Research
- Endocrinology
Background:
- Type 2 Diabetes Mellitus (T2DM) management involves complex decisions requiring patient-centered approaches.
- Shared Decision-Making (SDM) is crucial for integrating clinical evidence with patient values in T2DM care.
- Existing research on SDM in T2DM is fragmented, hindering a comprehensive understanding of its evolution and implementation.
Purpose of the Study:
- To conduct a bibliometric analysis of scientific publications on Shared Decision-Making (SDM) in Type 2 Diabetes Mellitus (T2DM).
- To identify trends, key influencers, thematic structures, and collaboration patterns in SDM research for T2DM.
- To highlight gaps and areas for future research and global collaboration in T2DM patient care.
Main Methods:
- Bibliometric analysis of publications from Web of Science, Scopus, and PubMed (up to December 31, 2024).
- Data analysis using Bibliometrix (R) to assess productivity, collaboration networks, and thematic mapping.
- Exclusion of studies with superficial SDM mentions or focus on adjacent constructs.
Main Results:
- Analysis included 272 documents (2000-2024) from 31 countries, with a 14.5% annual publication growth rate peaking in 2023.
- The United States led in output and collaboration; Mayo Clinic and Montori VM were identified as leading institutions and authors, respectively.
- Core themes included patient decision aids and adherence, with emerging focus on minimally disruptive medicine; collaboration is concentrated in the Global North.
Conclusions:
- Research on SDM in T2DM is expanding but predominantly originates from Anglo-European contexts.
- Limited participation from the Global South necessitates efforts to strengthen global collaboration.
- Developing inclusive, patient-centered SDM models for diabetes care requires addressing underrepresented perspectives and fostering broader engagement.

01:15Diabetes: Management and Pharmacotherapy
The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.

01:22Diabetes Mellitus: Type 2 and Gestational
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
01:22Diabetes Mellitus: Overview and Type I Subtype
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

01:29Therapeutic Drug Monitoring: Affecting Factors
Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.
01:24Type II Diabetes II: Pathophysiology
PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
01:23Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast, controlled...
