QUDOS is a cross-sectional population study aiming to answer key questions about diabetes and its complications in Qatar as well as identify factors associated with the development and progression of diabetes complications.
QUDOS aims to gain a better understanding of diabetes in primary and secondary care over a period of 24 months.
A range of patients with diabetes will be sampled (including those with Type 1 diabetes as this group is under-studied in Qatar). This will be important in designing appropriate intervention plans that will improve diabetic patients' health conditions to prevent or delay the onset of complications and will provide a strong foundation for longitudinal study.
The broad objectives of the study are:
QUDOS 1: Aims to recruit 1,700 diabetic patients (including 200 with type 1 diabetes mellitus (independent of healthcare setting)) attending the hospitals and primary care and to collect the following data:
QUDOS 2: To further characterise 500 patients, from the total 1500 patients with T2DM recruited in QUDOS 1, who accept to continue with QUDOS 2 (a more detailed study and assessment).
This phase aims to concentrate on the following aspects:
10,925 studies on the registry are indexed under Diabetes Mellitus; 1,318 are open to participants now.
This study's enrollment of 475 is above the median of 233 across 2,218 observational studies indexed under Diabetes Mellitus.
