Screening system for the detection of unknown or poorly controlled diabetes mellitus in a tertiary hospital: A retrospective study.

Rationale: Hospitalization may be a valuable chance for the detection of unknown and uncontrolled diabetes mellitus (DM). There is a screening tool at our hospital: in case of high inpatient plasma glucose level, an A1c value is added if no available from the last 3 months.

Aims And Objectives: Our objective was to analyse the population with A1c ≥ 9% detected through this system from 2021 to 2023.
