%X <B>BACKGROUND: </B>In July 2011, Cystic Fibrosis (CF) was added to the Newborn Bloodspot Screening Programme in Ireland. The Irish Comparative Outcomes Study (ICOS) is a historical cohort study established to compare outcomes between clinically-detected and screen-detected children with CF. Here we present the results of economic analysis comparing direct healthcare costs in the first 2 years of life of children born between mid-2008 and mid-2016, in the pre-CF transmembrane conductance regulator modulator era.<BR><B>METHODS: </B>Healthcare resource use information was obtained from Cystic Fibrosis Registry of Ireland (CFRI), medical records and parental questionnaire. Hospital admissions, emergency department visits, outpatient appointments, antibiotics and maintenance medications were included. Costs were estimated using the Health Service Executive Casemix, Irish Medicines Formulary and hospital pharmacy data, adjusted for inflation using Consumer Price Index data from the Central Statistics Office. A Negative Binomial regression was used, with time in the study as an offset.<BR><B>RESULTS: </B>Overall participation was 93 %. After exclusion of those with meconium ileus, data from 139 patients, with follow-up to 2 years of age, were available. 72 (51.8 %) were from the clinically diagnosed cohort. In the final model (n=105), clinically diagnosed children had 2.62-fold higher costs per annum (p<0.0001), when adjusted for confounders, including homozygous ΔF508 or G511D mutation, socio-demographic factors and time between diagnosis and first CFRI interaction.<BR><B>CONCLUSIONS: </B>There are few studies evaluating economic aspects of newborn screening for CF using routine care data. These results imply that the benefits of newborn screening extend to direct healthcare costs borne by the State.
