Shared Data, Better Outcomes: Advancing Diabetes Care in Wisconsin

Diabetes remains one of Wisconsin's most significant health challenges affecting more than 526,000 Wisconsinites, but there is encouraging news: Wisconsin health systems continue to exceed national performance on blood sugar control and recently have demonstrated further improvement in patient outcomes.

Our latest edition of WCHQ Health Insights highlights the burden of diabetes in Wisconsin and the opportunities to improve outcomes through earlier diagnosis, effective management, and coordinated care.

Key insights from this month’s report:

  • Wisconsin health systems have improved blood sugar control by 27%, with an additional 54,000 patients having good control of their diabetes.
  • Investing in early detection and evidence-based treatment offers improved health outcomes, avoiding an estimated $78 million in healthcare costs across Wisconsin.
  • More than one-third of Wisconsin adults still have higher-than-normal blood sugar levels with nearly 125,000 Wisconsinites living with undiagnosed diabetes.
  • Patients from underserved populations are less likely to achieve good blood sugar control, increasing their risk of preventable diabetes-related complications.
  • For more information on diabetes care quality, see WCHQ’s Quality Measures.

Improving outcomes for patients with diabetes is one of our priority initiatives. Examples of strategies being implemented at member health systems to improve care for patients with diabetes include:

  • Integrating pharmacists into primary care teams to manage medications.
  • Screening for Social Determinants of Health that affect diabetes outcomes, such as food insecurity and medication costs.
  • Increasing access to care through telehealth visits.

The progress highlighted in this report demonstrates what is possible when healthcare organizations work together around shared data and common goals. Continued investment in prevention, early detection, and effective diabetes management can help more Wisconsinites live healthier lives while reducing avoidable complications and healthcare costs.
