Original Title: Coste-efectividad del cribado neonatal de la tirosinemia tipo I (actualización)

Authors' objectives: • To evaluate the cost-effectiveness of newborn screening for TH1. • To determine the cost-effectiveness of including early detection of TH1 by MS/MS in a newborn screening programme. • To estimate the budget impact of implementation of early detection of TH1 through MS/MS in NHS.

Authors' results and conclusions: Results Cost-effectiveness systematic review Only a HTA-report from the Institute of Health Economics of Alberta (Canada), located by manual search and published in 2016, could be considered. The objective of this report was to evaluate the effectiveness, safety and cost-effectiveness of adding seven conditions (including TH1), to the Canadian newborn screening program using Markov-type modeling. The methodological quality of the economic evaluation was high. The perspective used is that of the third payer, including exclusively direct healthcare costs. The authors reported a cost per child screened of CAD $ 28.40 (€ 21.20 from 2021) compared to CAD $ 26.50 (€ 19.78 from 2021) per child not screened. The difference in life years between both strategies is 0.00006, which results in an ICER of CAD $ 31,723.53/LYs (approximately € 23,666.66/LYs in 2021). Although the authors do not mention a country willigness to pay (WTP) reference (and, therefore, do not specify whether the alternative is considered cost-effective or not), they declare that, since the detection of a single condition or a combination of them produces an additional benefit for health with additional costs for the system, its adoption depends on the availability of funds. Economic analysis The cost-effectiveness analysis shows that the mean cost per child not screened is € 33.03, while the cost per child screened is € 35. Both the LYs and QALYs are higher with the newborn screening strategy, which results in an ICER of 30,034.32 €/QALY from the NHS perspective and 28,017.90 €/LY from societal perspective. Both values are close to the cost-effectiveness threshold estimated for Spain at €25,000/QALY. When analyzing different scenarios varying the parameters about which there is greater uncertainty, it is obtained that the incorporation of TH1 to the neonatal screening program would be a cost-effective alternative if the price of the additional reagent used for the detection of TH1 by MS/MS does not exceeds €0.20/reagent. The budget impact analysis shows that the incremental cost per child screened in the first year is around € 0.37, which is equivalent to € 123,801 for all newborns born in Spain. Conclusions • There is limited scientific literature evidence on the costeffectiveness of TH1 newborn screening using MS/MS. Only one HTA report has been located that concludes that the incorporation of TH1 into a newborn screening program should be assessed based on budget availability. • The cost-effectiveness analysis carried out in this report with updated data from Spain concludes that the implementation of TH1 newborn screening would be a cost-effective option from the NHS perspective if the price of the reagent used to detect the disease does not exceed €0.20/reagent. • According to the budget impact analysis, screening TH1 would have a low incremental cost per newborn, of approximately € 0.37 the first year.

Authors' methods: A systematic review of the scientific evidence on the cost-effectiveness of newborn screening for TH1 was carried out, for which a search strategy was developed in electronic databases: MEDLINE, EMBASE, Web of Science (WOS) and Cochrane since 2013 until April 2021. A cost-effectiveness model has been developed that compares two alternatives: implement newborn screening for type I tyrosinemia or carry out clinical detection of this disease. The perspective of the analysis was that of the SNS, taking into account direct healthcare costs, expressed in 2021 euros. Effectiveness was measured using the Quality-Adjusted Life Years (QALY) measure. Both costs and effectiveness were discounted at 3%. Finally, a budget impact analysis was carried out to report the cost of including newborn screening of TH1 in the NHS.
