Top 10 hospitals by diabetes diagnoses in 2021

Approximately 11.3% of the U.S. population has diabetes, so there’s a significant public health incentive to understanding the disease and where it is most prevalent. What’s interesting is that of the estimated 37.3 million people who have diabetes, more than 8.5 million of those people have an undiagnosed case of diabetes.

Each year, 1.4 million Americans are newly diagnosed with diabetes. Let’s explore the top 10 hospitals with the most diagnoses for type 2 diabetes mellitus without complications.

Which hospital had the most diabetes diagnoses?

It’s important to note that there are numerous diagnoses related to diabetes, and this list focuses on the diagnosis of type 2 diabetes mellitus without complications (ICD-10 code E119).

In 2021, Cleveland Clinic Main Campus had the most diabetes diagnoses, with 353,445 total diagnoses. In second is University Hospital, with 114,623, and in third is Mount Sinai Medical Center, with 76,460.

Most of the hospitals on the list are in states with a high rate of adult obesity. Specifically, Ohio, Michigan, Delaware, and Texas have more than a 35% adult obesity rate. New York has a 26.3% rate, and Illinois has a 32.4% rate. These states’ obesity rates are significant because obesity is associated with a higher likelihood of developing diabetes.

What is diabetes?

Diabetes is a long-term disease that inhibits the body’s ability to produce insulin, thus affecting the way the body converts food into energy.

There are three types of diabetes:

  • Type 1 diabetes
  • Type 2 diabetes
  • Gestational diabetes

While the exact cause is unknown, Type 1 diabetes is believed to be caused by an autoimmune reaction that prevents the body from producing insulin. Type 2 diabetes arises when the body has trouble using insulin effectively to maintain blood sugar levels. Gestational diabetes develops during pregnancy and typically resolves after childbirth.

Over time, diabetes can cause a variety of other medical conditions, including kidney disease and heart disease.

When should you be tested for diabetes?

All adults should be tested for diabetes every three years, starting at age 45. It may make sense for some adults to test more often, depending on risk factors. Testing often involves a hemoglobin A1C test, which checks blood sugar levels over a three-month period.

How is diabetes treated?

There are a few ways people living with diabetes can treat and manage the condition. Healthcare providers will typically have patients monitor their blood sugar levels, use insulin therapy, and take oral drugs.
