- What is the economic impact of universal screening?
There are no published data as of yet on the economic impact of newborn screening for SCID/T-cell lymphopenia. However, there was a family study (see references) that was performed a couple of years ago that showed substantive differences in mortality in infants who were screened vs those who were not. Also, since mortality is almost universal in all infants with classic forms of SCID by 2 years of age and there are significant healthcare costs to repeated hospitalizations and treatment for infection and other comorbidities, let alone lost lives and productivity, both from patient (future) and families who have to take care of them, it is quite reasonable to predict that the economic impact of NBS SCID would be significant. At the moment, no one has put the dollars and cents numbers together but as more and more states are initiating NBS SCID that will be one of the outcome parameters that will be assessed.
