Boutrous ML, et al. - Patients with upper extremity vascular injuries who were admitted during a 5-year period to a level I trauma center based in a university hospital setting were assessed to determine the rates of long-term follow-up and outcomes. Based on the Area Deprivation Index (ADI), researchers divided patients into two groups; the first group representing the lowest quartile of patients and the second group the higher three quartiles. Despite patients’ having similar outcomes in regard to complication and amputation rates in both the high and low ADI groups, they identified lower rates of long-term follow-up in patients with the lowest ADI scores as opposed to the higher ADI.
