Details

Step 1

Complete CRF: Admission

Press 'save' and open CRF: Criteria to initiate RRT

Step 2

Complete CRF: Criteria to initiate RRT:

 

• Indicate one or more criteria to initiate RRT and their priority score (from 1 [low] to 3 [high])

 

• In patients with ARF, choose which RIFLE criteria are applicable

 

• Indicate what you expect to happen using the technique you have chosen

Press 'save'; the next CRF for the chosen modality will automatically open

Step 3

Complete CRF: Change to modality:

 

• Fill in all mandatory fields using the measure/legend

 

• Be advised that there is one CRF for each hour of observation. This depends on the chosen RRT modality (for IHD: 0.0 hours, 4.0 hours and treatment end; for CVVH, CVVHD, CVVHDF, HVHF, CPFA: 0.0 hours, at 1.0 hour, 3.0 hours, 6.0 hours, 12.0 hours, 24.0 hours, and every 24 hours thereafter and at treatment end)

 

• In the case of treatment interruption or end, specify date/time (for definition of treatment interruption or treatment end, see under 'Guidelines given in the CRF', in the text)

 

• In the case of change of treatment modality after treatment interruption, fill in CRF: Criteria to modality. Then go back to the start of step 3. Once in CRF: Change to modality, do not forget to select the new modality chosen

Press 'save' and terminate CRF: Change to modality
