Perinatal transfer of genetic information: developing an algorithm for reporting cystic fibrosis prenatal test results to the newborn screening program.

Purpose: This study explored the feasibility of statewide reporting of cystic fibrosis fetal diagnostic testing results to the newborn screening program through the birth hospital.
Methods: We evaluated trends in offering and documenting cystic fibrosis carrier screening among prenatal care providers through a survey of 100 medical records of patients who gave birth at St. Vincent's Hospital Manhattan. The hospital's protocol for reporting human immunodeficiency virus testing history to the state program was delineated and adapted in developing an algorithm for cystic fibrosis. Feedback from hospital staff with regard to data transcription and the prospect of transferring cystic fibrosis prenatal information was obtained.
Results: Of 98 patients who had prenatal records made available to the birth hospital, 62% had cystic fibrosis carrier screening, 14% declined screening, and 24% had no documentation of their screening history. The hospital staff viewed the transcription of information as relatively simple; however, missing information is a common occurrence that delays the process and results in incomplete data transfer.
Conclusions: Perinatal transfer of cystic fibrosis prenatal information modeled on the system used for reporting human immunodeficiency virus testing history is feasible. However, it will require standardized reporting of cystic fibrosis screening and testing history on the mother's prenatal records among prenatal care providers.
