RESUMO
Surveys in high-income countries show that inadequacies and deficiencies can be common for some nutrients, particularly in vulnerable subgroups of the population. Inadequate intakes, high requirements for rapid growth and development, or age- or disease-related impairments in nutrient intake, digestion, absorption, or increased nutrient losses can lead to micronutrient deficiencies. The consequent subclinical conditions are difficult to recognize if not screened for and often go unnoticed. Nutrient deficiencies can be persistent despite primary nutrition interventions that are aimed at improving dietary intakes. Secondary prevention that targets groups at high risk of inadequacy or deficiency, such as in the primary care setting, can be a useful complementary approach to address persistent nutritional gaps. However, this strategy is often underestimated and overlooked as potentially cost-effective means to prevent future health care costs and to improve the health and quality of life of individuals. In this paper, the authors discuss key appraisal criteria to consider when evaluating the benefits and disadvantages of a secondary prevention of nutrient deficiencies through screening.

This paper provides the first estimates of impact and cost-effectiveness for integrated HIV and nutrition service delivery in sub-Saharan Africa. HIV and undernutrition are synergistic co-epidemics impacting millions of children throughout the region. To alleviate this co-epidemic, UNICEF supported small-scale pilot programs in Malawi and Mozambique that integrated HIV and nutrition service delivery. We use trends from integration sites and comparison sites to estimate the number of lives saved, infections averted and/or undernutrition cases cured due to programmatic activities, and to estimate cost-effectiveness. Results suggest that Malawi's program had a cost-effectiveness of $11-29/DALY, while Mozambique's was $16-59/DALY. Some components were more effective than others ($1-4/DALY for Malawi's Male motivators vs. $179/DALY for Mozambique's One stop shops). These results suggest that integrating HIV and nutrition programming leads to a positive impact on health outcomes and should motivate additional work to evaluate impact and determine cost-effectiveness using an appropriate research design.

Undernutrition has significant implications for patients' clinical condition and economical consequences for the NHS. However, due to continually increasing prescribing costs for sip feeds, treating undernutrition is often seen as very costly. An audit project in Lothian was undertaken to look at the appropriateness of sip feeds being prescribed. The project found there was a significant level of inappropriate prescribing with 30% of patients having their prescriptions for supplements stopped as they were deemed unnecessary. In view of this, the community dietitians involved developed and introduced a nutritional care pathway to allow a systematic and evidence-based approach to the identification and treatment of undernutrition.

OBJECTIVE: To determine the efficacy and cost-effectiveness of providing oral supplementation early in the course of malnutrition for hemodialysis (HD) patients. DESIGN: The study design consisted of 3 groups: an experimental group, a control group of patients with mild hypoalbuminemia (HA) (serum albumin [SA] = 3.5 to 3.7 g/dL), and a comparison group of patients with moderate to severe HA (SA = 2.5 to 3.4 g/dL). SETTING: Ten outpatient hemodialysis centers in southeast lower Michigan. PATIENTS: Treatment and control groups consisted of 32 HD patients with mild HA. Fourteen HD patients with moderate to severe HA comprised the comparison group. INTERVENTION: The experimental group received diet counseling and oral supplementation, and the control group received diet counseling only. The comparison group received physician-prescribed oral supplements and dietary counseling to permit comparison of the experimental treatment with current supplementation practices. MAIN OUTCOME MEASURES: Differences between groups in the number of patients reaching nutritional repletion, change in SA levels at the end of the study, and follow-up periods, were tested using chi-square analysis. Analysis of variance was used to compare group differences in treatment duration to repletion and number of hospitalization days. RESULTS: During the study period, significantly more patients reached nutritional repletion in the experimental group and control group (50% and 57%, respectively) than in the comparison group (7%). Overall, repletion occurred more quickly in the experimental group (3.2 +/- 1.7 months) than in the control group (3.5 +/- 1.2 months), with a larger number of patients in the experimental group repleted by month 2 of the study phase. During follow-up, patients in the experimental group were far more likely to maintain nutritional repletion or continue to improve (61%) than patients in the control group (14%). Although too few patients were hospitalized to show statistical significance, there was a trend toward greater numbers of hospital days in more malnourished patients (208 days for the comparison group), followed by those with mild HA who did not receive oral supplements (107 days), and the experimental group (71 days). CONCLUSION: Although the sample size for this study was too small for the results to be conclusive, it appears that use of nutritional supplements early in the course of malnutrition may provide benefits such as, attaining nutritional repletion more quickly, which results in less product usage. It is also more likely that good nutritional status will be maintained after supplementation is discontinued.

Malnutrition is not a new or a rare problem. In studies involving more than 1,327 hospitalized adult patients, 40% to 55% were found to be either malnourished or at risk for malnutrition, and up to 12% were severely malnourished. Surgical patients with likelihood of malnutrition are two to three times more likely to have minor and major complications as well as increased mortality; and their length of stay can be extended by 90% compared with the stay of well-nourished patients. Hospital charges are reported to be from 35% to 75% higher for malnourished patients than for well-nourished patients. Obtaining data to assess the nutritional status of patients is essential to optimal patient care, especially for patients at high risk for malnutrition. Nutrition assessment can be done with readily available and relatively inexpensive methods. But it is not enough to assess and identify malnutrition. Outcomes are improved and costs are saved only when appropriate intervention follows. This article identifies many well-conducted, published studies that support the findings that health outcomes of malnourished patients can be improved and that overall use of resources can be reduced by nutrition counseling, oral diet and oral supplements, enteral formula delivered via tube, and parenteral nutrition support via central or peripheral line. Early nutrition assessment and appropriate nutrition intervention must be accepted as essential for the delivery of quality health care. Appropriately selected nutrition support can address the problem of malnutrition, improve clinical outcomes, and help reduce the costs of health care.
