2. A Look from Alert Data
IPI helps identify where operational problems are
But it does not tell you why problems occur or how to solve them
Survey: Organization factors(47%), Technology factors (44%), Individual factors (attitude, errors, habits, 8%), other (2%)
Known predictors of workarounds:
Safety Culture, Burnout, Leadership quality, Team communication, Trust, Empowerment, “It’s safe to speak up”
The “Soft” Stuff Microchips can’t tell you.

3. Alerts by Outdated DLL (Example)
Avg. is 24.8% of all pumps w/ alerts

4. A Look from Pump Management Data
~ 2% increase per day
Update
Update

5. How Long Are Pumps Up-to-Date?
Keep track of individual pumps using pump serial numbers
Follow pump status with time to see if there is any pattern within and across update cycles
E.g., problem pumps?
Pump 1
NC-OP P
NC-NC C
P + P + C = 2P + C
Pump 2
NC-NTD
NC-NTD + P + C
Pump 3
C + C + C = 3C
Update Cycle 1
Update Cycle 2
Update Cycle 3

6. Summary of Pump Status Patterns
HOSPITAL A
HOSPITAL B
Current at the end of 3 / 3 Update Cycles
497 (58% of the pumps).
All of these were current 70 days on average.
Only 230 pumps (27%) were current at least 80% of the time (76 days).
251 (37% of the total pumps).
All of these were current 54 days on average (68%).
Only 13 pumps (1.8%) were current at least 80% of the time (64 days).
Current at the end of 2 / 3 Update Cycles
194 (22.8%) of the pumps were Current at the end of two UC.
175 pumps (25.51%) on average were current for 30 days.
Never current
75 (8.8%)
159 (23.17%)

7. Research Plan
A pilot study on how visual ques can be used to inform clinicians on which pumps are up-to-date and its effectiveness
Need hospital collaborators for a pilot project and later for larger scale dissemination
