Overview

Analysis reveals geographic distance impacts emergency department and inpatient utilization in sickle cell disease patients, suggesting tailored care delivery solutions.

Key Points

  • The study examines how residential distance from specialized care affects healthcare utilization in sickle cell disease patients.
  • Analyzed visit data from patients living within 100 miles of a specialized SCD care center, grouped in 10-mile increments.
  • Examined visit counts for five service types: ED, pain infusion clinic, inpatient, and outpatient visits.
  • Used zero-inflated Poisson regression models to assess associations between distance and utilization rates for each service type.
  • Healthcare utilization varied significantly by distance from the medical center, with complex patterns by service type.
  • Patients living 30–40 or 40-50 miles away exhibited the highest predicted ED use, averaging 18.96 and 39.78 visits respectively.
  • Pain infusion clinic utilization peaked at 80–90 miles away, averaging 12.12 visits, while higher inpatient use occurred in those living 70–80 miles away.
  • 54% of patients showed significant variation in outpatient visit frequency based on distance.
