PEER REVIEWED
The number of patients who had a diagnosis of prediabetes recorded in the Intermountain Healthcare enterprise data warehouse from January 1, 2011–December 31, 2014, was 17,142. Of these, 9,661 patients were excluded because they did not have an office visit with a provider any time from August 1, 2013–July 31, 2014. Of those not excluded, 7,481 had an opportunity to be invited by a physician to the DPP. Of these, 619 were excluded for these reasons: 340 had diabetes before or within 2 months after study enrollment, 102 had miscoded data related to prediabetes diagnosis, 77 were invited by a provider but declined participation, 63 had a medical condition not related to weight loss or diabetes prevention, 38 began weight loss education before DPP program initiation, 9 underwent weight-loss surgery, 8 were aged <18, and 2 died during study period. Twenty people met more than 1 exclusion. After these exclusions, 6,862 were considered for study: 573 participated in the DPP, and 6,289 did not. Of the participants, 384 participated in the Prediabetes 101 class, 213 participated in Medical Nutrition Therapy, and 54 participated in Weigh to Health.
