Experimental: NPH and regular insuline group
For the group receiving NPH and regular 2/3 and 1/3 formula will be followed. If Nil per os (NPO), patient will receive NPH twice daily but AM dose will equal to PM dose. Regular insulin given along with NPH will be held while patient is NPO. A correctional dose of regular insulin will be given for any blood glucose >180 mg/dL. If subjects were not eating, they could also receive correctional doses of regular insulin. Correctional insulin could be given four times daily with meals or at bedtime.
|Drug: NPH and regular insulin|
Active Comparator: glargine and humalog group
Half of the total insulin dose will be given as glargine once daily, either in the AM or in the PM, depending on when the patient was enrolled. The other half of the total daily insulin dose was given as humalog; doses were divided equally between breakfast, lunch, and dinner. An additional correctional dose of humalog will be given for any blood glucose >180 mg/dL. If subjects were not eating, they received glargine once daily and could also receive correctional doses of humalog. Correctional humalog could be given four times daily with meals or at bedtime.
|Drug: glargine and humalog|
The effect of insulin depends not only on the pharmacokinetics and pharmacodynamics of a particular preparation, but also on patient specific factors which includes state of inflammation, obesity etc. Although effect on glucose disposal is the central to insulin action, there could be differences of insulin action on other metabolic parameters. It is not known if there is a difference in suppression of inflammation with improved glycemic control which could vary with analog insulin. It is unknown if natural insulin (NPH, recombinant human insulin with protamine) differs from insulin analogs (glargine and detemir, made by substituting amino acid in the native sequence) in terms of metabolic outcome other than glucose disposal.
At this point it is uncertain if there is any clear benefit of use of lantus over NPH in inpatient glycemic management. Currently, both lantus and NPH based regimen is practiced in inpatient hospital setting. Current practice of inpatient insulin regimen is based more on familiarity of physicians with a particular insulin type and personal preference rather than evidenced based knowledge. Lantus is an expensive insulin preparation compared to NPH with uncertain benefit in inpatient setting. Current research proposal will compare this two insulin based regimen in the management of diabetes of hospitalized patients. Information obtained through this research will guide the investigators practice in this institution as well as in other institutions.
