However, the current scenario regarding the management of T2DM in Indonesia remains unclear. Thus, the present study aimed to describe the baseline characteristics, treatment types, and quality of care indicators in T2DM patients under the DISCOVER CaReMe Registry program. Methods: DISCOVER CaReMe Registry program is a multi-centre, prospective, and observational study conducted over 3 years from 2018-2021. The data were collected from five different sites across Indonesia. Results: A total of 539 patients with a mean age 98 A 9. 76 were enrolled in the study. Among them, 62% . of patients were females. Further, the mean glycated haemoglobin (HbA1. levels were 8. 54 A 2. 88%, which was much higher than the American Diabetes Association (ADA) recommended target of 7%. Overall, 69% of the patients had HbA1c levels of >7%. First-line treatment in patients was mostly metformin . %). As per the quality-of-care indicators, 72. 2% of patients use glucose monitoring equipment and receive education about diabetes treatment and management. Furthermore, the knowledge of T2DM among patients was assessed in over 85% of cases, and misconceptions about the condition were clarified by healthcare professionals (HCP.

Conclusion: Despite a good knowledge and quality of care indices in patients with T2DM, the proportion of patients with HbA1c levels of >7% is still higher. There is an urgent need for diabetic management programs to prevent such complications in the Indonesian population. Keywords: DISCOVER CaReMe study. Type 2 diabetes mellitus. quality of care. HbA1c. INTRODUCTION Type 2 diabetes mellitus (T2DM) is one of the leading global and regional causes of death worldwide, besides cardiovascular diseases (CVD. and chronic kidney diseases (CKD. T2DM accounts for approximately 90% of live cases and 1. 8% of deaths in low to middle- income countries. Among these countries. Indonesia is ranked seventh globally with the highest absolute prevalence of diabetes, affecting 7 million people in 2019. It is predicted and projected to reach 16. 6 million by 2045. Evidence in the literature suggests that diabetic management conditions are suboptimal in low to Acta Med Indones - Indones J Intern Med A Vol 57 A Number 3 A July 2025 Rulli Rosandi middle-income countries such as Indonesia. The increasing prevalence of diabetes poses a great threat to the healthcare system and may cause an economic burden to society. Diabetes is associated with an increased risk of cardiovascular events and mortality. Several clinical and cross-sectional studies suggest crosstalk between renal, cardiovascular, and diabetic complications. thus, a multi-disciplinary approach is needed for the management of 4 Glycaemic control, management of these co-morbidities, and optimal therapies are obligated for the effective treatment of patients with T2DM. Glycated haemoglobin (HbA1. was considered an optimized measure of glycaemic The American Diabetes Association (ADA) AuStandards of Medical Care in DiabetesAy has recommended guidelines for the components of diabetes care, general treatments, and tools to evaluate the quality of care in clinical practice. As per ADA, the recommended HbA1c target of <7% without significant hypoglycaemia is Next, clinical guidelines for diabetes management recommend the use of metformin as first-line glucose-lowering therapy. In a hospital-based cross-sectional study. Aminda et . recruited 195 patients with T2DM and observed the effect of adherence to antidiabetic The authors reported that the early detection and management of diabetes with first-line glucose-lowering therapy showed better glycaemic control. 6 When monotherapy fails, combination therapy is approached for the treatment of diabetes. In a VERIFY trial, it was shown that early combination therapy can improve blood glucose levels better and delay the need for insulin than a stepwise approach for T2DM management. 7 Due to contradictory studies in the literature, there is no consensus on the treatment therapies. The T2DM treatment is recommended on the basis of patient characteristics such as age, body mass index (BMI), duration of diabetes, comorbidities, and other risk factors using an individualized and patient-centred approach. An important aspect of T2DM and its management protocols, i. , public awareness, is poor, which makes it more challenging to control the disease and other associated factors Acta Med Indones-Indones J Intern Med . lood glucose and HbA1. 9 Studies on the role of healthcare professionals in public awareness regarding diabetes management and in improving quality of care indices are limited. Based on this background, the DISCOVER CaReMe Registry program aimed to describe the baseline characteristics, associated comorbidities, development of complications, treatment types, and quality of care indicators in patients with T2DM.

Site Selection The data were collected from five different sites across Indonesia by healthcare investigators, including physicians, endocrinologists, and other specialists who were involved in the management of patients with type 2 diabetes mellitus. These five sites included were primary, secondary, tertiary, private owned, or state-owned health care facilities. Patient Recruitment A total of 539 patients were enrolled on the basis of inclusion and exclusion criteria. Patients aged Ou18 years old who had type 2 diabetes, heart failure, and/or chronic kidney disease were included in the study. Conversely, patients with type 1 diabetes or having life-threatening comorbidity with a life expectancy below 1 year were excluded from the study. Written informed consent was obtained from each participating patient before their enrolment.

Additionally, the inclusion and exclusion criteria were kept minimal to ensure the enrolment of patients with different backgrounds, ethnicities, and socioeconomic statuses into the DISCOVER Primarily, the baseline demographic data, such as age, sex, ethnicity, education level, employment status, health insurance coverage, , were collected after enrolment of the patients. In the DISCOVER CaReMe Registry program, a total of 539 patients with a mean age of 58. A 9. 76 were enrolled from five different sites, whereas close to 16000 patients were enrolled from 38 different countries in the DISCOVER global observational study. 11 Our finding reported that approximately 69. 8% of patients had public or governmental health insurance coverage. In a study. Putri and Murdi . reported that 65% of the Indonesian population was insured under National Health Insurance, known as Jaminan Kesehatan Nasional (JKN) in 2016. 12, 13 The study is in concordance with our data. In the clinical characteristics, the mean BMI of the recruited patients was found to be 68 A 4. 01 kg/m2, which is classified as at risk of overweight or obese. In the DISCOVER study, the BMI was reported as in the range of obese, i. , 29. 4 A 6 kg/m2, much higher than our 11 In another study. Cholil et al. examined the current state of diabetes care in Indonesian patients with T2DM and reported the mean BMI of 25. 4 A 4. 2 kg/m2. 14 This range also falls in the category of obese and overweight, viz. >25 kg/m2. The PERKENI guideline proposed Acta Med Indones-Indones J Intern Med overweight and obesity as prime risk factors for T2DM15. Other than these, several studies revealed the association of co-morbidities such as dyslipidemia, hypertension. CVDs, and CKDs with obesity and T2DM. In the present study, the Indonesian population was found to be hypertensive with a systolic blood pressure 38 A 49. 33 mmHg. Smoking and alcohol are also considered risk factors of T2DM. However, more than 65% of the population were non-smokers and non-alcoholics. Further, the medical history associated with CVDs. CKD, and diabetes complications, including heart failure, diabetic foot, retinopathy, and major and minor hypoglycemic events, was noted. Due to the high rate of missing data on medical history, it was difficult to find any association. Next, the diagnostic tests such as blood tests . hite blood cells, hematocrit, and hemoglobi. , metabolic parameters (HbA1c, fasting and postprandial plasma glucose (FPG and PPG)), lipid profile . otal cholesterol, triglycerides, highand low-density lipoproteins (HDL and LDL)), and renal functions . erum creatinine, estimated glomerular filtration rate, urine albumin, blood urea nitrogen, and uric aci. were measured. our study, the levels of FPG and PPG were higher than the normal recommended ranges, i. , 185. A 92. 63 and 249. 88 A 113. 02 mg/dL, respectively. The plasma glucose data indicate suboptimal glycemic control, suggesting an increased risk of developing diabetic complications. 17 Another important metabolic parameter, i. HbA1c, the mean levels of HbA1c were 8. 54 A 2. 88%, which was much higher than the American Diabetes Association (ADA) recommended target of 7%. About 69% of the patients had HbA1c levels of >7%. In the DiabCare project, the authors reported inadequate diabetes control in two surveys conducted in Indonesia during 20082009 and 2013- and 2014, two-thirds of patients did not achieve the recommended HbA1c target of less than 7%. 14, 18 In another study. Gomes et al . described the characteristics of patients with T2DM initiating second-line glucoselowering therapy in the global DISCOVER study The authors reported that HbA1c levels were consistently high. Approximately >30% of patients had an HbA1c measurement of >9. Vol 57 A Number 3 A July 2025 Characteristics and Care Quality of Patients with Type 2 Diabetes in Indonesia which is similar to our findings. 11 In our previous DISCOVER study in Indonesia, we collected the data of 221 subjects from 13 sites and reported HbA1c levels of 8. 0A1. 8% at baseline and over a 3-year follow-up after initiating second-line 18 The missing data on HbA1c levels were very high due to affordability issues and suboptimal reporting of HbA1c in clinical settings and geographic regions of low- to middle-income countries. In terms of treatment, we found that >40% of patients had antidiabetics as first-line treatment, which is much lower than the reported metformin monotherapy as the most common first-line therapy in most of the studies. About 55Ae91% of patients diagnosed with T2DM received metformin monotherapy. 11, 19, 20 The reasons may be due to the high rate of missing data or lower metformin monotherapy usage in South-East Asian countries. Lastly, the quality-of-care indices were assessed in 72 patients in our study. Among them, 72. 2% of patients use glucose monitoring equipment and received education about diabetes treatment and management through group About >85% of patientsAo knowledge of T2DM was checked, and misconceptions about T2DM were clarified by HCP at the health In terms of nutritional advice. HCP advised a Audiabetic dietAy to 69. 4% of patients. Based on the quality-of-care data, we may suggest that the patients have good knowledge regarding the management of T2DM. However, attention should not be diverted as the data could be obtained from 13% of the total enrolled population in the study. To the best of our knowledge, this is the first DISCOVER study that has collected data on quality of care. The effective management of the T2DM condition heavily relies on patient understanding and adherence to treatment goals, which are often hindered by inadequate education and In our opinion, the lack of education regarding treatment goals among Indonesian patients with Type 2 diabetes is a concerning issue that warrants immediate attention. Based on the high rate of missing data, we opined that many patients may not fully comprehend the importance of maintaining blood glucose levels within target ranges, adhering to medication regimens, adopting healthy lifestyle habits, and seeking regular medical monitoring. Without this crucial knowledge, individuals with Type 2 diabetes may struggle to effectively manage their condition, leading to worsened health outcomes and increased healthcare costs. Furthermore, cultural factors and socioeconomic disparities exacerbate the education gap among Indonesian patients with Type 2 diabetes. Limited access to healthcare resources, language barriers, and traditional beliefs about illness and treatment can hinder patients' ability to receive accurate information and support for managing their diabetes effectively. Additionally, the stigma associated with chronic diseases like diabetes may discourage individuals from seeking help or adhering to treatment recommendations. Therefore, concerted efforts are needed to improve diabetes education and awareness initiatives in Indonesia. The study has major limitations: . Only baseline data of the enrolled patients were . The DISCOVER registry was formulated as an observational design, due to which data was collected as per routine clinical practice at each participating site, resulting in a high rate of missing data. Due to the high rate of missing data, parameters such as medical history and comorbidities could not be associated with T2DM. In future studies, this challenge could be addressed through the implementation of standardized electronic data capture systems across all sites, enhanced training for site personnel on data entry, periodic data quality audits, and scheduling dedicated data collection sessions to ensure accurate and complete datasets. The quality of care indicators were assessed in 72 patients only due to a lack of necessary resources, structured education programs, and trained staff at the participating sites, to administer the standardized quality-of-care questionnaire during routine clinical practice. All participating sites were not able to collect this specific data. however, the data remains of significant value. Rulli Rosandi CONCLUSION The DISCOVER CaReMe registry program highlighted the baseline characteristics, treatment options, and quality of care metrics in patients with T2DM in Indonesia. Despite good knowledge and quality of care indices, the current scenario of T2DM in the Indonesian population is poor. Therefore, there is an urgent need for more aggressive risk-factor management in patients with T2DM. Our findings also highlight the potential for healthcare policy in Indonesia to prioritize and expand standardized diabetes education programs despite relatively high knowledge levels among patients. Integrating such programs into primary care services, supported by multidisciplinary teams and government-led initiatives, could enhance patient engagement, improve glycemic control, and promote long-term outcomes across both urban and rural healthcare settings.
