Overview

Overview

The treatment of SCLS requires a combination of medications, and prices range according to severity of symptoms presented in individual patients. Whereas medication such as Bevacizumab can be $66.60 per 10 mg for 2 weeks, others like infliximab used for a duration of 5 mg/kg every 8 weeks may cost $99,171.00. It is also important to note that medication such as Theophylline and Terbutaline may accrue increased costs due to the neccesity of increased monitoring.

Cost-effective therapy

Cost-effective therapy

Medications used can be divided based on classes, such as Endothelial signal transduction and Immune modulators. Prices vary for medications within every given class.

Treatment Mechanism of Action

Endothelial signal transduction

Bevacizumab
  • Bevacizumab costs in 2014 averaged around $9324 for a total duration of 8 weeks
  • The average price of the drug was $66.60 per 10 mg given at 5 mg given every 2 weeks[1]
Epoprostenol
  • Over a two 6-month period, epoprostenol was estimated to cost around $19,483.48. This did not include equipment use of $283.25 which brought the total cost near $19,766.73[2]
Theophylline + Terbutaline
  • Due to the risk of toxicity, Theophylline requires increased monitoring. Due to this, costs can average around $121.40 per patient per month[3]
  • After studying admission for 13 days and 16 days, Theophylline costs were estimated to be around $12,864.22[4]
  • Compared to other tocolytics, Terbutaline required increased monitoring due to a higher incidence of adverse events resulting in an average cost of $399.02. Comparatively, nifedipine had an average cost of $16.75[5]

Immune modulation

Corticosteroids
  • Corticosteroids are commonly utilized to reduce underlying inflammation and has been used for SCLS
  • Septic shock, one of the underlying causes SCLS, requires corticosteroids as part of the treatment regimen
  • Hydrocortisone use averaged around $1,254,078.00 per QALY[6] and a 90-day monetized benefit of $25,539 per patient[7]
Infliximab
  • Studies show that, compared to other immune modulators, infliximab was more cost-effective when given at 5 mg/kg every 8 weeks at $99,171.00. Comparatively, adalimumab given at 40 mg every other week totalled around $316,378 and vedolizumab given every 8 weeks averaged $301,969[8]
IVIG
  • Annual costs for IVIG in the USA during 2014 were on average $9,720 per infusion or $108,016 per patient[9]
  • Other recent studies showed IVIG to be more cost-effective, averaging a cost of $78,814. When compared to plasmapheresis, IVIG was found to be more cost-effective[10]
Plasmapheresis
  • For use in inflammatory conditions, plasmapheresis costs averaged $101,140 per patient[11]
