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.

The argument against glycemic index: what are the other options?

There is debate among professionals regarding the use of the glycemic index (GI) for meal planning. In type-1 diabetes, there are 4 studies (average duration approximately 4 weeks) comparing high versus low GI diets; none reported improvements in HbA1c, and although 2 reported improvements in fructosamine, 2 reported no differences. In type-2 diabetes, there are 12 studies (average duration approximately 5 weeks); 3 reported improvements in HbA1c and fructosamine, 5 reported no differences in HBA1c, and 3 reported no differences in fructosamine. In adults, there is limited evidence that a low GI diet is beneficial for weight loss or satiety. Three epidemiologic studies reported that a low GI/glycemic load (GL) is associated with a reduced risk of developing diabetes or prevalence of insulin resistance; however, 5 studies report no association between GI/GL and the risk of developing diabetes, fasting insulin or insulin resistance, or adiposity. In general, the total amount of carbohydrate in a meal is the primary meal-planning strategy for people with diabetes. The GI can be used as an adjunct for the fine tuning of postprandial blood glucose responses. Other food/meal-planning interventions have been shown to be more effective than the use of the GI.

Lactation, diabetes, and nutrition recommendations.

Human milk is recommended for infants throughout at least the first year of life. Breastfeeding is also recommended for infants of women with preexisting diabetes or gestational diabetes. Dietary Reference Intakes (DRIs) 2002 provides recommendations for energy and macronutrients for all ages and for pregnancy and lactation. During the first 6 months, infants receive an average of 500 kcal/d from human milk, and during the second 6 months 400 kcal/d. To cover this need for the first 6 months of lactation, women need an additional energy intake of 330 kcal/d plus the approximately 170 kcal/d that is supplied by the women's tissue stores, and for the second 6 months 400 kcal/d. The DRIs also set recommended levels for both the infant and mother for carbohydrate, protein, and fats. Women with type 1 diabetes may have problems initiating breastfeeding, and with hypo- and hyperglycemia during lactation. Breastfeeding may have long-term beneficial effects on glycemia in women with gestational diabetes. More research is needed on all aspects of lactation in women with diabetes.

Effectiveness of weight loss and maintenance interventions in women.

Overweight and obesity in women contribute to increased risk of many health problems, including type 2 diabetes. A systematic review of the weight loss literature found 17 articles in which women were the sole subjects and studies were a minimum of 1 year or longer in duration. Data were pooled and average weight loss and maintenance for women at 6 and 12 months was determined for each of the six interventions. Diet as the primary intervention resulted in a weight loss of approximately 7 kg at 6 months (approximately 13% of their initial weight), which was maintained to 12 months. When specific goals for physical activity or weight loss medications were combined with diet, better outcomes were experienced. Regardless of the intervention, at approximately 6 months a weight loss plateau occurred. All of the studies included at least monthly follow-up.

Evidence-based medical nutrition therapy for diabetes.

The 2002 American Diabetes Association (ADA) nutrition principles and recommendations are classified according to the level of evidence available using the ADA evidence grading system. Research also supports medical nutrition therapy (MNT) as an effective therapy in reaching treatment goals for glycemia, lipids, and blood pressure. Recommendations for carbohydrate, protein, dietary fat, micronutrients, and alcohol are summarized. The first priority for persons requiring insulin therapy is to identify a food/meal plan that can be used to integrate an insulin regimen into the person's lifestyle. MNT for type 2 diabetes progresses from prevention of obesity or weight gain to improving insulin resistance to contributing to improved metabolic control. The progressive decline in beta-cell failure requires that MNT progress from MNT as monotherapy to MNT in combination with oral glucose-lowering agents to MNT with insulin therapy. Monitoring of outcomes is essential to assess the outcomes of lifestyle interventions or to determine if changes in medication(s) are necessary.

Nutrition therapy for diabetic nephropathy.

Human observational studies report no association between protein intakes less than 20% of energy intake and the development of renal disease. With protein intakes greater than 20% of energy intake there is an association between protein with increased albumin excretion rate. Once albuminuria is present, intervention studies suggest a beneficial effect on renal function with a reduction of protein to 0.8 to 1.0 g/kg/d with microalbuminuria and to 0.8 g/kg/d with macroalbuminuria. Restriction of sodium to 2400 mg/d or possibly for some to 2000 mg/d assists in the control of hypertension. In macroalbuminuria, there may be additional benefits in lowering phosphorus intake to 500 to 1000 mg/d. There is no strong evidence to suggest benefit from vegetable or plant proteins over animal protein, but there is evidence for benefit on renal function, glucose, lipids, and blood pressure from weight-maintaining diets meeting guidelines for a healthy diet.

Diabetes medical nutrition therapy: practical tips to improve outcomes.

PURPOSE: To describe the evolving and expanding role of nurse practitioners (NPs) in providing diabetes medical nutrition therapy (MNT) as the United States faces epidemics of diabetes and obesity. DATA SOURCES: Scientific literature and reports from the public health, diabetes, and nutrition fields. CONCLUSIONS: Although clinically effective for both prevention and treatment of diabetes, MNT is often underutilized. The majority of people with diabetes are cared for by primary care providers; the role of NPs as primary care providers is evolving and expanding. NPs are recognized as leaders who creatively adapt to the rapidly changing health care delivery system. IMPLICATIONS FOR PRACTICE: NPs can serve as role models by presenting accurate, basic nutrition messages, referring patients to registered dietitians for MNT, reinforcing nutrition and the importance of lifestyle change as primary treatments for their disease, and following up on their patients' progress with nutrition interventions.
