RESUMO
In times of economic crisis and a national healthcare system that absorbs more than 7% of the gross domestic product, there is a need to "rethink" healthcare practice. EHealth is part of this process of improving accessibility to services, use of available resources and coordination of program choices, and is an indispensable tool for implementing this cultural and management revolution. How realistic is it, today, to think of implementing a digitalized healthcare practice network? To settle this question is essential for today's national healthcare system.
RESUMO
The IRT screening test for the use in diagnosing newborns with CF has a high sensitivity but is not very specific resulting in a large number of screened positive infants found to have a normal sweat test. The aim of this study was to analyze the differences in b-IRT levels among different groups of newborns positive to NBS.Population data included all b-IRT positive (>99th centile) neonates born in Lombardia from 2000 to 2007. The hypertrypsinemic newborns were divided into four groups, according to CF status (noncarrier, carrier, CFTR-RD, CF).Among a total of 717,172 newborns screened within the study period, 7,354 newborns were found positive to NBS and were included in the study. An overall statistically significant difference in b-IRT levels was found among the four groups (p < 0.001), while b-IRT values did not differ between noncarriers and carriers. b-IRT levels had a low predictive accuracy in correctly identifying the four different groups (c-index: 0.60), but the accuracy was high in discriminating between classic CF and carrier or noncarrier status in neonates positive to NBS. The IRT level on the initial blood specimen obtained at birth differs based on the CF genotype, although a wide range of individual variation may occur.
