Abstract

Objective: To examine the cost-effectiveness of prophylactic probiotics on necrotizing enterocolitis (NEC) prevention in very low birth weight (VLBW) infants. Study design: We built a decision-analytic model using TreeAge. Effectiveness was assessed using quality-adjusted life-years (QALY). Primary outcome was an incremental cost-effectiveness ratio (ICER) expressed as cost per QALY gained. Costs were expressed in 2017 US dollars. Deterministic and probabilistic sensitivity analyses (SA) were performed. Results: For the base case analysis, the ICER of probiotics versus no probiotics for the prevention of NEC in VLBW infants was $1868/QALY. SA revealed that probiotics became cost-saving at a NEC rate of 6.5% and higher or with incremental NEC cost of $37,500 or higher. Conclusions: Our model demonstrated that prophylactic probiotics were a cost-effective strategy in NEC reduction. SA confirmed that the model is customizable to various clinical settings and thus, can aid in understanding the economic impact of this intervention.
