Project ER ONEMedical Facility Design for Today’s Threats Michael P. Pietrzak, MD, FACEP
Hospital Design Objectives Competing Priorities? • 1. Function • Clinical, administrative, operational Support • Medical Consequence Management • 2. Esthetic • Healing environment • Image • 3. Protection • From Elements • Security
New Environment • New threats • New public expectations • Protect • Preparedness: respond and manage • Implication-- scalability • Approach to design • Multi-objective optimization • Approach not new-- just more objectives
New Objectives • Medical Consequence Management • Capability to handle the existing and emerging threats • Scalability • Ability to gracefully scale response in time of surge • Threat Mitigation • To minimize the consequences to the facility, assets and individuals within
ER One Premise • Hospitals are a key part of domestic preparedness response effort • Hospitals should provide protection and capability • If this were so, the “system” would be stronger • What is the best way to do this? • Integral to planning or after design?
ER One Premise • MCM, threat mitigation and scalability features could be “designed-in” • Operational requirements and facility mission-- still the primary drivers • Financial, site, zoning realities • What can be achieved within the given template and constraints?
History: Hospitals • Teutonic Knights- Threat Mitigation • Crusaders and Hospitallers
Hospitals:History • Knights of Malta-1160 • Renaissance • Hotel like St. John’s Hotel Dieu
Hospitals: History • 50s and 60s • Efficiency in terms of walking distances (Yale study) • Windowless rooms to ensure ‘seal’ • 70s • Patient comforts begin to enter equation • 80s • Facilities to attract patients Dartmouth shopping mall • 90s • Cost constraints • 2000s ???? Carolinas

Threat Mitigation Da Vinci wrote to Duke Ludovico Sforza in 1483 as an engineer-- To make bridges 'indestructible by fire and battle’ Build 'chariots, safe and unassailable’ To this he added at the end that he was also an architect, a sculptor and a painter. Ravelin
Facility Operational Needs Assessment Threat Assessment Vulnerability Analysis Define Constraints Define Critical Axis Establish Desired Threat Mitigation Features and Priorities Select Solutions: Multi-objective Optimization Achieving Threat Mitigation A Process
Prioritization • What is most vulnerable? • High access areas • External perimeter • What needs to be protected most? • Critical axis • ED, ICU, Surgery, Critical lab, Imaging, Command and Control, Environmental support systems, Connectivity • High human density areas
