Brief summary:
Despite a significant problem with out-of-control glucose levels in patients with diabetes receiving corticosteroids for a variety of illnesses, there are no published protocols addressing how to adequately treat corticosteroid-induced hyperglycemia. Investigators propose to test a protocol using scheduled dosing of NPH (Neutral protamine Hagedorn) insulin for inpatients with diabetes receiving corticosteroids. NPH insulin action is ideally timed to counteract corticosteroid-induced hyperglycemia, and the dose is added to the patient's usual insulin regimen and timed to correspond to the corticosteroid dosing regimen. Investigators will prospectively enroll eligible consented patients with diabetes who are receiving corticosteroids as part of their treatment in a large county hospital, will randomize them to intervention or control groups, and will monitor their glucose levels during their inpatient stay. The protocol will demonstrate improved control of glucose levels with minimal risk of hypoglycemia, and will provide a practical and readily implementable protocol using NPH insulin as therapy for corticosteroid-induced diabetes.

Detailed description:
As above.

Arms:
arm 1: Receive NPH with each corticosteroid dose during the study duration (2-5 days).

Low dose corticosteroids High dose corticosteroids Eating and 6a-8p 0.15 units NPH/kg 0.3 units NPH/kg NPO(nothing by mouth) or 8p-6a 0.1 units NPH/kg 0.2 units NPH/kg arm 2: Receive usual care with background insulin and correction factor for duration of study (2-5 days)

Interventions: intervention 1: NPH intervention 2: Correction Factor
Intervention descriptions: intervention 1: NPH given per study table based on steroid dose and patient weight in kg. intervention 2: Given at 2 units per 50 mg/dl over 200 mg/dl and increased to 3 units/50 mg/dl over 200 if glucose rises to over 300 mg/dl. Administered qid during study duration.
