Abstract
Background: Home parenteral nutrition (HPN) requires intensive medical case management by practitioners with expertise in the provision of nutrition support. There is expenditure of considerable time and resources for management of these patients not covered by any of the traditional reimbursement mechanisms. The costs associated with this unreimbursed input and follow-up are most often borne by the Nutrition Support Team or individual practitioners. Reimbursement by home care agencies to physicians for management of patients after discharge cannot be done because this may be construed as a "kick-back" for referral of patients to particular home care agencies. Methods: Time and costs associated with management of HPN patients after discharge from the hospital were assessed using a cost-identification analysis of 24 different factors. Daily activity logs were kept by the Nutrition Support Team members over a 2-week period. Costs of space and furnishings were calculated. Results: On average, a total of 25 h/d was spent by members of the Nutrition Support Team on our HPN patients. Variable activities accounted for 5640.1 hours of time with fixed support at 890.3 hours. This computes to a total annual personnel cost of $168,482 ($1982 per patient). If costs of furnishings and space are also included, the overall cost of all resources was $175,989 per year or $2070 per patient. Conclusion: Significant and currently nonreimbursed costs are involved in HPN patient management. These costs are most often absorbed by the Nutrition Support Team and should be considered when evaluating total costs of HPN. (Journal of Parenteral and Enteral Nutrition20:113-119, 1996)
