ObjectiveThe study's objective was to determine the impact of care directed by a specialty-trained nurse practitioner (NP) or physician assistant (PA) on use of basal-bolus insulin therapy and glycemic control in a population of noncritically ill patients with diabetes.MethodsA retrospective review of diabetes patients evaluated between July 1, 2011 and December 31, 2011 was conducted. Patients cotreated by a specialty-trained NP/PA were compared with patients who did not receive such care.ResultsIn total, 171 patients with 222 hospitalizations were cotreated by an NP/PA and 543 patients with 665 hospitalizations were not. Patients with NP/PA involvement were younger, and had more frequent hyperglycemia, and had greater corticosteroid use than patients without NP/PA involvement (P<.01 for all). Basal-bolus insulin therapy was administered to 80% of patients with NP/PA involvement and 34% of patients without it (P<.01). After adjustment for age, sex, hyperglycemia measures, and corticosteroid use, the odds of basal-bolus insulin therapy being administered were increased significantly through NP/PA care (odds ratio, 3.66; 95% confidence interval, 2.36-5.67; P<.01). After adjustment for these variables and insulin regimen, NP/PA care was significantly correlated with lower mean point-of-care glucose levels at 24 hours before discharge (P = .042).ConclusionDiabetes care assisted by an NP/PA trained in inpatient diabetes management results in greater use of recommended basal-bolus insulin therapy and is correlated with lower mean glucose levels before discharge. Adapting this model for use outside an endocrinology consult service needs to be explored so that the expertise can be brought to a broader inpatient population with diabetes.
