2. 42 30 vs. 52 Background Anisha Check font size?
Minutes
Deloitte’s recommended cleaning time based on hotel housekeeping practices 42 52
Average cleaning time in University Hospital
Average cleaning time in

vs.
Anisha
Check font size?
This discrepancy needs to be bridged in order to inform staffing decisions.

6. Engineering Approach Steve Housekeeper Interviews: 10 Conducted
Modified to make interviews more informal
Conducted during down time
Used prepared questions as guideline
Steve

7. Engineering Approach *Note to presenter: talk about wash step Steve
Time Studies and Observations:
Sample size: 36 observations
Conducted in pairs
Record cleaning time of each step
Record key information and exceptions
*Note to presenter: talk about wash step
Steve
Reminder: 8-Step Discharge Process
Wash In, Wash Out
Pull Trash
High Dust
Damp Wipe
Clean Bathroom
Dust Mop Floor
Damp Mop
Inspect the Room

8. Engineering Approach Steve
Data Analysis:
Descriptive Statistics
Each clean type, room type, hospital combination
Universal steps of cleaning process
Quantitative Data shows high variation due to…
Initial room condition
Hospital floor culture
Housekeeper routine
Unanticipated events (e.g. patient in room)
Qualitative Data
Importance assessed by frequency of occurrence
Steve
Priority = Frequency of Observation occurrence X Expected Impact

James
Damp wiping accounts for 50% of a discharge clean

15. Qualitative Findings and Conclusions
Discharge Cleans:
Variation in sequence of steps
High dust on as-needed basis
Discharge cultures by floor, by unit
James
Daily Cleans:
Patient in room
Improvised tracking sheets

16. Recommendations James Define who breaks down room
Discharge Cleans:
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
Daily Cleans:
James
Official tracking sheets
Standardize work procedures
Future Work:
Standardize work procedures
Narrow scope by floor, by unit

17. Expected Impact Baseline ranges for clean times
Future study repeatability
Data for staffing model decisions
James
