Maxwell et al reported the Post-Pancreatectomy Diabetes Index to predict the risk of diabetes following a pancreatectomy. This can help to identify a patient who may require more aggressive management. The authors are from Emory University.
Patient selection: pancreatectomy, 18 to 90 years of age
Parameters:
(1) hemoglobin A1c or eA1c in percent
(2) body mass index (BMI) in kg per square meter
(3) age in years
(4) type of surgery
