The exact number of sickle cell patients in the U.S. is unknown, because data on the genetic disorder is lacking.
Health interventions have made it possible for people with sickle cell in the U.S. to live well into adulthood. But the transition out of pediatric care comes with many challenges.
My two articles (I was originally writing three, but ended up with two lengthy articles) for the Fellowship were definitely acquired through an illuminating process.
Over and over I encountered heads of medical institutions in the area who gave me their polished spin on why there weren't enough physicians in the area and why our huge Medi-Cal population wasn't being served. The two are intertwined as not having enough doctors/resources for the privately insured means that the physicians who DO live here will flock to the patients who pay. Which are not Medi-Cal patients.
