The Children's Hospital (TCH) registered dietitians (RD) participated in a statewide study by The Colorado Dietetic Association to justify inclusion of nutrition services, as “medical nutrition therapy,” in the basic health care benefits package of all Coloradans. Utilizing a case study format adapted from the Massachusetts Dietetic Association, thirteen case studies in seven specialty areas from TCH were retrospectively reviewed. Three categories of patient care were identified (preventive, acute and outpatient) in which nutrition intervention could have a positive effect. For each case reviewed, the RD intervention and patient health outcome was described. Resources saved were defined on the basis of historical data and clinical nutrition practice and included reduction of therapies such as G-tube placement and prolonged enteral/parenteral nutrition support. Intervention Costs were derived from TCH data for usual product and service charges and the Intervention Benefit was defined as the cost of Resources Saved. The final Cost Savings was determined as the intervention Benefit minus the intervention Cost. Projected cost savings were consistently realized in all the cases of nutrition intervention reviewed in this study with the greatest projected savings in the preventive and outpatient areas. However, cost of avoided therapies other than nutrition during extended hospitalization were not included in this review. Therefore, the projected cost savings in the acute care setting is underestimated. An average of the three categories projected a cost savings of fifty dollars for each dollar spent on nutrition intervention. A positive impact on the clinical course; of patient management was seen in addition to the cost savings. In the ever changing health care climate there is a significant contribution toward cost reduction utilizing nutrition intervention.
