DRAUP implementation and effectiveness outcomes and measures

OutcomesMeasures
Implementation
Adoption of DRAUP
  1. Number of times POCUS is used for CVC confirmation after right internal jugular vein catheter insertion

  2. Risk profile assessment using three validated survey instruments (MFS, RTS, SUS)

Deadoption
  1. Number of CXR not performed because POCUS is used for CVC confirmation

  2. Risk profile assessment using three validated survey instruments (MFS, RTS, SUS)

Fidelity of DRAUP
  1. Percentage of full DRAUP algorithm compliance (checklist)

  2. Percentage of appropriate% POCUS images for interpretation

PenetrationNumber of actual CVC insertions where DRAUP is used divided by the number of possible CVC insertions where DRAUP could have been used
Effectiveness
Diagnostic accuracy of POCUS in CVC confirmation
  1. Accuracy of POCUC for CVC complication detection

  2. Sensitivity of POCUS for CVC malposition detection and/or PTX

  3. Specificity of POCUS for CVC malposition detection and/or PTX

Safety of DRAUP
  1. In-hospital follow-up of ‘DRAUPed’ lines with CVC malposition and/or PTX (catheter duration, clinical complication intervention)

  • %appropriate, specifically defined POCUS images and screen labelling required for protocol; CVC, central venous catheter; CXR, chest radiograph; DRAUP, deimplementation of routine chest radiographs after adoption of ultrasound guided insertion and confirmation of central venous catheter protocol; MFS, malpractice fear scale; POCUS, point-of-care ultrasound; PTX, pneumothorax; RTS, risk-taking scale; SUS, stress from uncertainty scale.
