1 FSHP Disclosure Strategies for Glycemic Management in the Inpatient Setting: Guidelines vs. Reality Melissa Marshall, PharmD, BCPS Jeffrey Ruff, PharmD We do not have (nor does any immediate family member have) a vested interest in or affiliation with any corporate organization offering financial support or grant monies for this continuing education activity, or any affiliation with an organization whose philosophy could potentially bias our presentation. 1 2 Pharmacist Objectives 1. Identify the health consequences of uncontrolled hyperglycemia 2. Discuss the guidelines regarding inpatient management of hyperglycemia in noncritically ill patients 3. Compare treatment strategies including Basal-Bolus, Basal-Plus and Correctional 4. Identify obstacles to implementation of guideline-driven hyperglycemia management 5. Discuss strategies and options for implementation Technician Objectives Diabetes Prevalence & Burden Affects more than 340 million globally U.S. in million (9.3%); >20% of adults 1 in 3 by fold greater chance of hospitalization vs. no DM 7.7 million hospital stays 38% - 46% of non-critically ill hospitalized patients DM remains the 7 th leading cause of death 1. Identify the health consequences of uncontrolled hyperglycemia 2. Recall the guidelines regarding inpatient management of hyperglycemia in noncritically ill patients 3. Recognize different treatment strategies with insulin: Basal-Bolus, Basal-Plus and Correctional $176 billion (43% inpatient care) 4. Discuss key safety precautions associated with insulin use Corsino L, et al. [Updated 2014 Oct 4]. In: De Groot LJ, et al., editors. Endotext [internet].
