INTRODUCTION: Therapeutic plasma exchange (TPE) is often impacted by difficulties in obtaining an adequate and safe vascular access. This study evaluated the rates, predictive factors, and clinical outcomes associated with central venous catheter (CVC) use during the inpatient TPE procedures.

METHODS: The Nationwide Readmissions Database, 2016 to 2017 was used to identify hospitalizations with TPE with and without CVC insertion.

RESULTS: During the study period, there were 35 429 hospitalizations with TPE (pediatric 6.1%, mean ± standard deviation (SD) age 50.9 ± 20.0 years, female 52.7%). CVC insertion was documented in 24 414 (73.4%) adult and 1596 (73.5%) pediatric hospitalizations. In pediatric patients, age >15 years, higher disease severity, and private insurance were associated with higher odds of CVC insertion. In adults, female sex, obesity, concurrent hemodialysis, and higher disease severity were associated with CVC insertion. Adults with private insurance and both adult and pediatric hospitalizations at the teaching hospitals had lower odds of CVC placement. All patients with CVC insertion had longer length of hospital stay, and adults with CVC insertion also had higher hospital charges, higher in-hospital mortality, and lower likelihood of being discharged to home.

CONCLUSION: CVC insertion is performed for the majority of inpatient TPE procedures and CVC use appears to correlate with worse clinical outcomes.
