Abstract
Background: We compared outcomes of therapeutic plasma exchange (TPE) vs intravenous immunoglobulin (IVIG) among hospitalized patients diagnosed with Guillain-Barré syndrome (GBS). Methods: In a retrospective cohort study of 6642 records (2637 TPE and 4005 IVIG) from the 2002–2014 Nationwide Inpatient Sample, treatment type was examined as predictor of length of stay, total charges, and in-hospital death, with regression modeling using risk adjustment and propensity scoring to control for confounders. Results: Compared with those receiving IVIG, patients who underwent TPE experienced prolonged hospitalization by approximately 7.5 days, greater hospitalization costs by approximately $46,000, and increased in-hospital death with an odds ratio of 2.78. Results did not change after controlling for confounders through risk adjustment, propensity score adjustment, or matching. Conclusions: TPE may be associated with poorer healthcare utilization outcomes vs IVIG, although confounding by indication could not be ascertained.
