Economic Analysis of Exclusive Human Milk Diets for High-Risk Neonates, a Canadian Hospital Perspective

Background: There is increasing evidence that premature newborns and infants with low birth weight can benefit substantially from an exclusive human milk-based diet (EHMD), consisting of human milk supplemented with a pasteurized donor human milk-derived fortifier. However, compared with the standard infant diet, EHMD also represents a significant added cost to the hospital and/or health system, thereby raising important questions about the economic feasibility of incorporating EHMD into newborn care. Design: We conducted a cost analysis and estimated the potential cost savings to a Canadian tertiary hospital based on the attributable complications averted from EHMD among low-weight neonates. A meta-analysis was performed to derive input parameters. A probabilistic analysis was conducted to determine the probability that EHMD is cost saving and 95% confidence interval (CI) around our estimates. Results: Our findings show that providing EHMD to preterm infants under 750 g at birth and at the highest risk of developing major complications is likely to be cost saving in the amount of $107,567 (95% CI: −145,229 to 360,362) per year. Extending EHMD to higher weight classes may be economically feasible depending on the pricing of the human milk-derived fortifier and the baseline risk of complications in the hospital setting. Conclusions: This comprehensive study provides critical insight for hospital-based decision makers to evaluate the potential gains and uncertainties associated with improved nutritional care for neonatal patients.
