Diabetes care cascade

The diabetes care cascade tracks how many people with diabetes are detected, treated, and controlled—and what programs or tools try to close those gaps across health systems.

Prevalence alone does not equal care. Students need separate claims for population cascade metrics, health-system program reviews, and single-app self-management trials.

What the evidence shows

Drawn from 3 studies in this library. Mix labels say which citation roles are present; they are not a strength score. Supports means evidence for a finding; Challenges means evidence against a stated position; Qualifies marks scope.

• ○ Limited citations

  National STEPS data can show rising awareness while control stays low.

  Iranian STEPS analyses found diabetes prevalence and awareness climbing, treatment peaking then dipping, and glycemic control remaining low—illustrating cascade leakage after detection.

  Many countries run T2DM detection/adherence programs, but authors still judge them insufficient for rising burden.

  A review of ongoing T2DM care activities highlights detection, monitoring, and adherence efforts amid obesity/urbanization drivers and HIV/TB co-morbidity, while arguing current efforts under-match need.

  Smartphone self-management tools are one narrow cascade lever, not a system fix.

  A smartphone diabetes self-management application study for adults with type 1 diabetes tests digital support for day-to-day management rather than national awareness/treatment/control rates.

• What’s being done for T2DM care across Africa?

  With ~19M adults with diabetes (→47M by 2045 if unchecked), African systems are expanding diagnosis/adherence programs—but major gaps remain, especially with HIV/TB co-morbidity.

• Is Iran’s diabetes cascade improving over time?

  From 2004–2016 prevalence rose 8.4%→13.2% and awareness 53.5%→82.2%, but treatment (~36–46%) and control (~15–21%) stayed suboptimal.
