Background:Diabetes Mellitus (DM) is a major risk factor for many complications and glycaemic control prevents and delays such complications. The Raqeb registry aims toimprove diabetic patientscontrol of their diabetes by giving them glucometers. Objective:This study aims to determine the prevalence of type 2 diabetes (T2DM) glycaemic control in all regions of Saudi Arabia using Raqeb data, as well as outline the factors associated with uncontrolled T2DM. Methods:This paper conducted a registry-based cross-sectional study among all patients with T2DM who registered in Raqeb from October 16, 2018, to July 17, 2022. According to the American Diabetes Association, for non-pregnant adults, HbA1c can be used to assess glycaemic control according to the HbA1c target of < 7% (control DM) and ≥7 (uncontrolled DM). To identify glycaemic control determinants, the present study used multivariate logistic regression analysis, while SPSS v26 software was used for data entry and analysis. Results: In the study, the mean level of HbA1c of the patients was 8.4 (SD1.7) and approximately 86% of the patients had uncontrolled diabetes mellitus (HbA1c ≥ 7%). Multivariate analysis revealed that being over 45 years old, using hypoglycaemic agents (OHA) and insulin, being followed up in a diabetic centre and being from the Western, Southern or Northern regions were all significant predictors of poor glycaemic control. Meanwhile, the female gender and OHA treatment were linked to a lower risk of poor glycaemic control. Conclusion:Using data from Saudi Arabias Raqeb registry of T2DM patients, this different level of care database analysis over a five-year period revealed uncontrolled DM. An increased risk of uncontrolled DM in T2DM patients was seen in those over the age of 45 years and patients using OHA and insulin treatment, as well as people from the Western, Southern or Northern regions of Saudi Arabia.
