AbstractA minority of super-utilizing adults with sickle cell disease (SCD) account for a disproportionate number of emergency department (ED) and hospital admissions. We performed a retrospective cohort study comparing the rate of admission before and after the opening of a clinic for adults with SCD. Unique to this clinic was an intensive management strategy, focusing on super-utilizing adults with 12 or more admissions per year. ED/hospital and 30 days re-admission rates were compared, 1 year pre- and post-intervention, for those adults who established in the clinic. Prior to the intervention, 17 super-utilizers, comprising 15% of the pre-intervention cohort (n = 115), accounted for 58% of the total admissions and had an admission rate of 28 per patient-year. When pre- and post-intervention years were compared, rate of ED/hospital admission per patient-year for super-utilizers decreased from 27.9 to 13.5 (P < 0.001), while there was not a significant reduction for the entire cohort (7.1 vs. 6.1, P = 0.84). Similarly, the decrease in rate of 30 day re-admission was larger for the super-utilizers (13.5 per patient-year to 1.8, P < 0.001), than the whole cohort (2.6 per patient-year to 0.7, P = 0.006). Among the super-utilizers, the reduced rate of admission from the pre- to post-clinic intervention year equated to 252 fewer ED/hospital admissions and 227 fewer 30 day re-admissions. This management strategy focusing on super-utilizing adults with SCD lowered admission and 30 day re-admission rate.© 2014 Wiley Periodicals, Inc.
