Economic evaluation of enhanced staff contact for the promotion of breastfeeding for low birth weight infants.

Objectives: There is evidence that breastmilk feeding reduces mortality and short and long-term morbidity among infants born too soon or too small. The aim of this study was to evaluate the cost-effectiveness of enhanced staff contact for mothers with infants in a neonatal unit with a birth weight of 500-2,500 g from the perspective of the UK National Health Service.

Methods: A decision-tree model linked clinical outcomes with long-term health outcomes. The study population was divided into three weight bands: 500-999 g, 1000-1,749 g, and 1,750-2,500 g. Clinical and resource use data were obtained from literature reviews. The measure of benefit was quality-adjusted life-years. Uncertainty was evaluated using cost-effectiveness acceptability curves and sensitivity analyses.

Results: The intervention was less costly and more effective than the comparator in the base-case analysis for each birth weight group. The results were quite robust to the sensitivity analyses performed.

Conclusions: This is the first economic evaluation in this complex field and offers a model to be developed in future research. The results provide preliminary indications that enhanced staff contact may be cost-effective. However, the limited evidence available, and the limited UK data in particular, suggest that further research is required to provide results with confidence.
