Krol et al2 used an innovative mobile medic approach to conduct a cross-sectional survey that identified the acute and chronic health care needs of medically underserved populations residing in Mississippi after Hurricane Katrina. Data from 2 Children’s Health Fund mobile medical units at 23 sites in the Gulfport-Biloxi area included all patient encounters (ie, chief complaint, diagnoses, vaccines dispensed, prescription medications distributed, and referrals) from September 5 through 20, 2005. Out of the 1,187 recorded patient encounters, there were 1,428 documented reasons to visit the mobile medical unit.
