title: Utilization of the office, hospital and emergency department for adult sickle cell patients: a five-year study.
abstract: Sickle cell disease (SCD) is a hematological disorder that is manifested primarily by severe pain and chronic organ damage. Little normative data exists on what the usual healthcare utilization is of a population of SCD patients, especially adults. Our study analyzed the office, emergency department (ED) and hospital use data for 142 patients who received care for three consecutive years. Relationships between health service use, patient age, gender and sickle cell phenotype were described. Multivariate analyses studied relationships between demographic and clinical characteristics and levels of office, independent ED and inpatient encounters over a five-year period (1997-2001). We found female patients were older and had less ED and hospital admissions. The 20% highest inpatient utilizers accounted for 54% of the ED total visits, 52% of the ED independent visits, 54% of hospital bed days and 24% of office visits. The ED was a common place for utilization, with a mean of 7.4 visits per patient year, a third of which resulted in a hospital admission. The healthcare utilization of our adult sickle cell population is very complex, with a subset of our patients accounting for a majority of the resources used and female patients living longer but with less ED and hospital admissions.
