Abstract
Aging, higher prevalence of diabetes, worsening obesity, and hyperglycemia among potential donors increase the likelihood that pancreata will be declined by transplant centers. Hemoglobin A1c testing, also known as glycated hemoglobin testing, identifies a donor's average blood glucose concentration for the preceding 2 to 3 months and is the standard test for identifying prolonged periods of hyperglycemia.
To compare pancreas utilization rates before and after implementation of hemoglobin A1c testing.
A retrospective study of data from the New York Organ Donor Network was conducted. Potential donors were defined as standard criteria donors who had no history of diabetes and were not seropositive for hepatitis B or C. Criteria for "ideal" potential pancreas donors were based on age, body mass index, lipase level, and terminal creatinine level. Potential donors who did not meet the criteria for ideal donors were considered "expanded" potential pancreas donors. Pancreas utilization rate was defined as the number of pancreata transplanted divided by the number of potential pancreas donors.
Of 779 standard criteria donors, 691 (89%) were potential pancreas donors: 251 ideal (36%) and 440 expanded (64%) donors. In 2005 and 2006, before hemoglobin A1c testing, pancreas utilization rates were 21% and 18%, respectively. In 2008, 2009, and 2010, after hemoglobin A1c testing was incorporated, utilization rates were 27%, 28%, and 32%, respectively. Utilization of ideal donors increased from 33% to 51% (P= .003), and utilization of expanded donors increased from 11% to 17% (P= .05). Pancreas utilization increased 51.0%, and pancreas discards decreased 50.8% with the implementation of hemoglobin A1c testing.
Hemoglobin A1c testing may increase utilization of ideal and expanded criteria pancreata.
