Inpatient management of diabetes and hyperglycemia: implications for nutrition practice and the food and nutrition professional.

Although numerous guidelines and standards address the management of diabetes in outpatient settings, only recently has evidence been provided to issue standards of care to guide clinicians in optimal inpatient glycemic control for hospitalized individuals with diabetes or illness-induced hyperglycemia. Both the American Diabetes Association and the American College of Endocrinology recommend critically ill patients keep their blood glucose level as close to 110 mg/dL (6.1 mmol/L) as possible. In the noncritically ill patient, the American Diabetes Association recommends to keep pre-meal blood glucose as close to 90 to 130 mg/dL (5.0 to 7.2 mmol/L) as possible, whereas the American College of Endocrinology recommends pre-meal blood glucose be kept at 110 mg/dL (6.1 mmol/L) or less. Both organizations agree that peak post-prandial blood glucose should be 180 mg/dL (10.0 mmol/L) or less. Recent evidence has also led the Joint Commission on Accreditation of Healthcare Organizations to develop standards for a voluntary certification in the management of the patient with diabetes in the inpatient setting. It is important that food and nutrition professionals familiarize themselves with these recommendations and implement nutrition interventions in collaboration with other members of the health care team to achieve these new glycemic control targets. Food and nutrition professionals have a key role in developing screening tools, and in implementing nutrition care guidelines, nutrition interventions, and medical treatment protocols needed to improve inpatient glycemic control.
