Overtreatment is Common, a Study Finds
Dr. McCoy and her team used the data from the 2011-2014 National Health and Nutrition Examination Survey to determine how many Americans received overtreatment. Surprisingly, they found out that the dangers of overtreating diabetes are common.
They discovered that out of the 10.7 million adult participants with diabetes (none of whom were pregnant), 22% or approximately 2.3 million patients receive overly intense treatment.
The study identifies an “intensely treated” patient as someone who received medication to ensure that their HA1C level is normal (5.6% or lower).
A diabetic also receives intense treatment if they take 2 medications to keep their blood glucose levels in the prediabetes range.
The Patterns of Overtreatment
In a separate study published in the Journal of General Internal Medicine, the researchers analyzed the data from more than 78,000 participants with diabetes.
They found out that 11% of the participants had a “very low on-going blood sugar level”. This finding suggests that these patients were overly treated. However, only 14% of that subgroup had a “reduction” in their medication refills 6 months after the reading.
The investigators likewise noted that patients 75 years old and above, and those who qualified for state and federal health coverage, were more likely to be overtreated.
The problem with this particular finding is that patients aged 75 and older are considered “clinically complex”.
Who Are the Clinically Complex Patients?
The dangers of overtreating diabetes could be more prominent in clinically complex patients.
According to Dr. McCoy, clinically complex patients are not just less likely to benefit from intense treatment, but they are also more prone to hypoglycemia.
Aside from being at least 75 years old, patients can also be considered clinically complex if they have:
- Two or more limitations in performing their activities of daily living. For example, they have difficulty in dressing, eating, walking, etc.
- An end-stage renal disease.
- Three or more chronic conditions.
Alarmingly, in the Mayo Clinic study headed by Dr. McCoy, they noticed that being in the clinically complex category didn’t come into play on whether or not a person was intensely treated.
