Abstract
Objective: To estimate the cost-effectiveness of using an extensively hydrolyzed casein formula (eHCF) plus the probiotic Lactobacillus rhamnosus GG (eHCF plus LGG; Nutramigen* LGG®) compared to an eHCF alone as first-line dietary management for Immunoglobulin E (IgE)-mediated cow's milk protein allergy (CMPA) in the UK. Methods: Decision modelling was undertaken to estimate the probability of IgE-mediated cow's milk allergic infants being symptom free (i.e. not experiencing urticaria, eczema, asthma or rhinoconjunctivitis) and developing tolerance to cow's milk by 5 years. The model also estimated the cost (at 2016/2017 prices) of healthcare resource use funded by the UK's National Health Service (NHS) over 5 years after starting a formula, as well as the relative cost-effectiveness of the two dietary formulae. Results: At 5 years after the start of a formula the probability of being symptom free was estimated to be 0.97 and 0.76 among infants who were originally fed eHCF plus LGG and an eHCF alone, respectively. This encompassed the probability of children being asthma free at 5 years after the start of treatment, which was 0.99 and 0.91 in the eHCF plus LGG and eHCF alone groups, respectively. Additionally, the probability of acquiring tolerance to cow's milk was estimated to be 0.94 and 0.66 among infants who were originally fed eHCF plus LGG and an eHCF alone, respectively. The estimated total healthcare cost over 5 years of initially feeding infants with eHCF plus LGG was less than that of feeding infants with an eHCF alone (£4229 versus £5136 per patient). Conclusions: First-line management of newly diagnosed infants with IgE-mediated CMPA with eHCF plus LGG instead of an eHCF alone improves outcome, releases healthcare resources for alternative use, reduces the NHS cost of patient management and thereby affords a cost-effective dietetic strategy to the NHS.
