Qualitative Findings and Conclusions
Variation in sequence of steps
High dust on as-needed basis
Discharge cultures by floor, by unit
Discharge Cleans:
Patient in room
Improvised tracking sheets
Daily Cleans:Slide16
Recommendations
Define who breaks down room
Wipe bed first for time to dry off
Call dispatcher early if no next assignment yet
Wrap gown in used gloves for efficient disposal
Discharge Cleans:
Official tracking sheets
Standardize work procedures
Daily Cleans:
Standardize
work
procedures
Narrow scope by floor, by unit

Expected Impact
Baseline ranges for clean
times
Future study
repeatability
