Florida Study Finds Doctors Aren’t Diagnosing or Treating Most Cases of Prediabetes

Less than one-quarter of patients who met the criteria for prediabetes received drug or lifestyle modification treatment from their primary care physician, according to University of Florida College of Public Health and Health Professions researchers, who say the findings indicate physicians are missing opportunities for diabetes prevention. The study appears in the March issue in the Journal of the American Board of Family Medicine.

More than a third of U.S. adults have prediabetes, which is defined as having blood glucose concentrations higher than normal, but not high enough for a diabetes diagnosis. People with prediabetes have a greater risk of vascular problems, kidney disease, and nerve and retinal damage.

“We know that prediabetes is considered one of the biggest risk factors for the development of diabetes, with estimates ranging from 15 to 30 percent of people with prediabetes developing diabetes within five years,” said lead investigator Dr. Arch G. Mainous III, chair of the department of health services research, management and policy in the University of Florida College of Public Health and Health Professions. “We also know that 90 percent of people who have prediabetes don’t know they have it. So the question becomes where is the doctor in all this? Is the doctor identifying people with prediabetes, telling them about it and providing treatment? That’s what we wanted to find out.”

The Florida study analyzed data from the 2012 National Ambulatory Medical Care Survey, a survey of physician office visits that allows for national estimates of U.S. medical care. The researchers studied visits to general, family or internal medicine providers by patients age 45 years and older who had physician-ordered blood tests done within the past 90 days. About 34 percent of the patients had a blood glucose level between 5.7 and 6.4 percent, which the American Diabetes Association considers prediabetes. Of those patients, very few were told they had prediabetes, and only 23 percent received treatment for the condition, such as lifestyle modification counseling or drug therapy, as indicated in their medical records.

Low rates of prediabetes diagnosis and treatment might be expected when physicians don’t have patients’ blood test results available, Dr. Mainous said, but patients in this study had undergone recent blood tests.

“Even with blood test results in front of them, physicians weren’t detecting prediabetes in their patients in terms of making a diagnosis or providing some sort of management or treatment,” said Dr. Mainous, the Florida Blue endowed chair of health administration.
