History of Simulation Modeling at BJC
4
Mid-2009: Identified
simulation as a key opportunity for the system
2009 2010 2011 2012 2013
Early 2010: System-wide
in-house training
2014
Early 2014: In-house SIMUL8 training
Mid 2013: Re-emphasis on simulation modeling as a
valuable performance improvement tool
Early 2010: Begin using simulation
system-wide
Late-2009: Selection of SIMUL8 as
BJC’s modeling software
2014: Integration
into Black Belt curriculum
2013: Attempt #2 to build
internal capacity
2011: Attempt #1 to build
internal capacity
2014: Attempt #3 to build
internal capacity
Simulation Applications at BJC
5
• Administration
• Care Coordination
• Emergency Department
• Food Services
• Nursing Units
• Operating Room
• Outpatient Medical Practices
• Pharmacy
• Planning, Design &
Construction
• Radiology
• Revenue Cycle
Simulation type: Staff utilization
Questions:
1. What is the effect of variation in patient utilization on prescription
turnaround time?
2. What is the effect of staff resources on prescription turnaround time?
3. What is the impact of batching deliveries on prescription turnaround time?
Case Study 1: Mobile Pharmacy
6
Inputs (variables) Outputs Controls
• Patient utilization • Delivery batch size • Staffing models
• Prescription turn around time
• Resource utilization
• House-wide patient census
• Delivery time
Case Study 1: Mobile Pharmacy
7
Future State (45% Patient Utilization)
Results/Decision/Recommendations:
• With increased patient utilization, resource need less than originally
estimated
– i.e. originally anticipated adding 4 scanning stations to overall Mobile Pharmacy
workflow; simulation model revealed that only 2 additional scanning stations
necessary
Project Benefits:
• Prospective understanding of impact of increased patient utilization
• Validation of resource requests/new hires prior to initiating process
Case Study 1: Mobile Pharmacy
8
Simulation type: Staff utilization
Questions:
1. What is the impact of varying patient acuity and patient census on staff
capacity required for executing falls and pressure ulcer interventions?
Case Study 2: Preventable Harm Interventions
9
Inputs (variables) Outputs Controls
• Frequency of interventions
• Patient length of stay • Patient census • Type of staff to
respond
• Staff utilization • Intervention time by
patient fall & pressure ulcer acuity level
• Bed capacity • % isolation patients • Distribution of falls
acuity • Distribution of
pressure ulcer acuity
Case Study 2: Preventable Harm Interventions

Case Study 2: Preventable Harm Interventions
12
“Low” fall risk patients ( ~12 patients)
“Moderate” fall risk patients (~23 patients)
“High” fall risk patients (~15 patients)
Results/Decision/Recommendations:
• Over 12 hours of a 24-hour time period is spent on fall and pressure
ulcer interventions for the average patient census
Project Benefits:
• Limited role differentiation for fall & pressure ulcer interventions
between staff revealed processes that neglected human potential
• Importance of clarifying standard protocol: model revealed that
some low risk patients required more staff time because of unclear
intervention protocol
Case Study 2: Preventable Harm Interventions
13
Simulation type: Bed flow
Questions:
1. What is optimal number of pre-op and post-op beds?
2. What is the impact of shared pre-op/post-op beds?
3. How does families waiting in the pre-op/post-op bay affect flow?
Case Study 3: Pre-Op and Post-Op Bed Utilization
14
Inputs (variables) Outputs Controls
• Case mix • # Available pre-op &
post-op beds • Use of space
(shared/separate, families occupy room)
• Utilization by bed type (pre-op, post-op & shared)
• Number of ORs • ASA scores
Case Study 3: Pre-Op and Post-Op Bed Utilization
15
Results/Decision/Recommendations:
• Recommended number of beds ranged from depending on bed use
scenario (shared/separate bed pool, case load, bed use)
Project Benefits:
• Families staying in pre-op room had limited impact on number of
beds required (requirement increased by 1 bed)
• Standard ratio of pre-op/post-op beds to ORs (4:1) did not hold for
every scenario
– Impacted by unique needs of the pediatric population
