Extended Survival Analysis of the Dallas Newborn Cohort
The Dallas newborn Cohort is a large group of sickle cell patients which has been previously defined and used to make the most widely cited modern estimates of survival for children with sickle cell disease (SCD). We propose to use the national Death index, the DFWHC database, medical records from Children's Medical Center Dallas, Parkland and St. Paul university Hospital, to review existing records and extend a survival analysis of this patient group. This is important because our capcacity to follow up with this cohort after transition to adult care at age 18 has been limited and because of a recent study suggesting the young adult period is particularly high risk for this patient population.
