Test Don't Guess!
A Diabetes Program for Healthcare Professionals

For people to take action to prevent diabetes, they must first be aware that they are at risk.  Patients with dysglycemia (i.e. pre-diabetes) are at extremely high risk to eventually develop Type 2 diabetes mellitus (T2DM); a serious health problem associated with significant complications.

The Ottawa Model for Undiagnosed Dysglycemia/Diabetes (OMUD) is a systematic process to identify, manage and follow patients with previously unrecognized diabetes and dysglycemia, during and after hospitalization. 

Nearly one-third of individuals with T2DM go undiagnosed, and in many patients who are diagnosed there is a lag of several years between diabetes onset and diagnosis, a time during which complications can develop. The prevalence of previously undiagnosed dysglycemia/diabetes amongst hospitalized patients varies from 10-30%, depending on the population screened. Hospitalization affords an opportunity to identify people with unrecognized dysglycemia/diabetes and attach them to prevention programs or long-term diabetes care1.

How OMUD Works

A systematic approach in hospital:

  1. Identify patients with undiagnosed prediabetes and/or diabetes
  2. Manage the patient’s prediabetes and/or diabetes while admitted in the hospital
  3. Inform the patient and their family doctor or healthcare provider of the patient’s diagnosis
  4. Refer the patient to resources within their community

Become a Partnered Site

The University of Ottawa Heart Institute will provide partnered sites with a detailed four-phase OMUD Implementation Workplan, program resources and tools to systematically embed an evidence-based process to identify, manage and follow patients with previously unrecognized diabetes and dysglycemia, during and after hospitalization. 

Phase 1: Program Introduction
  • Introduction of OMUD protocol
  • Readiness assessment
  • Meet with medical, nursing, laboratory leaders, and program implementers at each department/hospital and secure/reaffirm project buy-in
  • Assess/reaffirm current clinical practices with respect to identification and management of undiagnosed dysglycemia/diabetes
  • Create department/hospital-specific workplans to strengthen OMUD implementation
Phase 2: Program Training
  • Training will be provided to program implementers at each of the hospital units and to health care professionals (HCPs) directly involved in OMUD program delivery.  A web-based training module has been developed to train HCPs about the importance of screening for undiagnosed dysglycemia/diabetes, and how to operationalize the OMUD protocol at the patient level.

Phase 3: Program Implementation
  • All patients without known diabetes admitted to selected units implementing the OMUD protocol will be screened for the presence of undiagnosed dysglycemia/diabetes using a HbA1C.
  • Apply treatment procedures in hospital.
  • Discharge summaries.
  • Referral to community-based diabetes education or cardiac rehabilitation programs.
Phase 4: Evaluation
  • Collect key indicators to summarize processes and outcomes.
