background
Background
  • Anesthesia-related complications are relatively rare events and congenital cardiac surgery is a relatively rare procedure so the only way to contemporaneously and accurately capture anesthesia-related data is through a multi-site model.
  • Patients with congenital heart disease have up to 85x greater likelihood of having an adverse event intraoperatively than non-cardiac patients, regardless of the procedure being performed.
participation
Participation
  • Data start date of January 1, 2010
  • Current fee schedule: $3500 per year, regardless of number of anesthesia providers or cases. This does not include any expenses associated with vendor fees and is in addition to any fees paid by the congenital heart surgeons.
  • Cases input into database may include not only cardiac surgical cases, but any procedures in which congenital cardiac anesthesiologists are involved: Cath Lab, Diagnostic and Interventional Radiology, General OR, ICU, etc.
results
Results
  • On August 1, 2011 we received back the first report from the STS-CCAS data collection efforts
  • 20 Programs paid the $3500 fee, of which 18 submitted at least some minimal data to DCRI during the Spring 2011 harvest for calendar year 2010
  • The results represent both full and partial calendar year submissions and many centers chose to enter only CV surgical cases at this time.

areas for improvement
Areas for Improvement
  • Report Writing
    • There were multiple areas where the report produced did not really match up what we were trying to ascertain. This is largely a formatting issue that can be easily addressed.
  • New Items
    • Updated drug listings
    • Updated complications
    • Better information about airway issues (preoperative FiO2, in-situ airways, airway intubation mechanism (DL, FOB, etc.)
areas for improvement20
Areas for Improvement
  • Ultrasound Guidance for CVL placement
  • New Dispositions
    • Discharge Home as planned
    • Admit to Floor as planned
    • Admit to ICU as planned
    • Unexpected admission to hospital or ICU
    • Perioperative Demise (within 24 hours of last anesthetic), regardless of cause
