  5. Current work Pandemic Emergency Response Preparedness Supplement – 2008 • Parent survey: NHAMCS • Again funded by OASPE

  6. Methods:NHAMCS • NHAMCS uses a national probability sample: • U.S. nonfederal general and short-stay hospitals • Data weighted to produce national estimates • Collects facility & visit level hospital characteristics • Facility level: emergency response supplement • Visit level: emergency and outpatient department records

  7. Methods:Emergency response supplement • Eight-page survey instrument • Delivered on site to hospital administrator by U.S. Census Bureau field representative • Self-administered by hospital staff member deemed appropriate by administrator • Collected later by Census field representative

  8. Emergency response plans • Scenarios: • Hospital overcrowding • Disasters • Mass casualties • Disease outbreaks • Terrorism • Choices: • in emergency response plan • implemented in actual incident during 2007 • not in emergency response plan

  9. Percent of hospitals with emergency response plans for selected types of incidents:United States, 2008 95% confidence intervals Percent • NUC-RAD = Nuclear-radiological. (2) EXP-INC = Explosive-incendiary • SOURCE: CDC/NCHS, National Hospital Ambulatory Medical Care Survey, 2008

  10. Collaboration with outside entities • Memorandum of understanding (MOU) with other hospitals to accept patients in transfer from the emergency department when no beds are available: • adults • pediatric patients to children’s hospitals • MOU with regional burn center to accept transfers in the aftermath of an explosive or incendiary incident • MOU with other outpatient facilities to augment outpatient services • Regional communication systems to track: • emergency department closures or diversions • available intensive care unit beds (adult, pediatric, neonatal) • available hospital beds (adult, pediatric, neonatal) • specialty coverage • Mutual aid agreements with other agencies to share supplies and equipment

  29. Ambulance diversion Total number of hours in 2007 that: • Emergency department (ED) was on ambulance diversion • Hospital was on trauma diversion • Hospital was on diversion for critical care cases

  30. Percent of hospitals on ambulance diversion status, by number of hours spent on diversion: United States, 2008 95% confidence intervals Percent Cut point based on mean of 220.4 hours spent on diversion. Distribution highly skewed with median and mode both equal to zero (no diversion hours). SOURCE: CDC/NCHS, National Hospital Ambulatory Medical Care Survey, 2008

  31. Key points:Explosions and fires • Preparedness for explosions and fires less frequent than for other mass casualties • Explosive terrorism infrequent in U.S. • No incidents since 2001 • More common internationally • Fires more common • 15,500 fires in high-rises (1996-1998) • 6% of these were in hospitals U.S. Fire Administration.

  32. Key points:Emergency department crowding ACEP recommends that hospitals develop adequate inpatient surge capacity by: • canceling elective admissions and procedures • 83.6% of hospitals have plans for this • opening unused areas • 52.3% have plans to use inpatient hallways • using alternate areas for extra critical care space • 50.7% of hospitals have this American College of Emergency Physicians (ACEP). National strategic plan for emergency department management of outbreaks of novel H1N1 influenza.

  33. Key points:Emergency department crowding Study of adverse events from admitting ED-boarded patients to inpatient hallway beds during overcrowding situations. • Compared to patients admitted to standard beds: • In-hospital mortality significantly lower for hallway patients • ICU transfers significantly lower for hallway patients • Conclusion: hallway boarding not harmful Viccellio et al.

Guidance for establishing crisis standards of care for use in disaster situations. Report Brief 1-4. 2009. • Only 43% of hospitals plan for adjusted standards of care for ventilators during mass casualties. • Model for developing such standards: • Triage system for using ventilators based on clinical factors related to survival potential • Implemented through health department • Supported by governor declaration • Liability protections in place Hick & O’Laughlin. Concept of operations for triage of mechanical ventilation in an epidemic. Acad Emerg Med 13(2):223-9. 2006.

  35. Key points:Epidemic drills • ACEP also recommends staging exercises to test validity of pandemic flu training and plans. • 59% of hospitals staged severe epidemic drills. • 33% included mass vaccinations. • 23% included community medication distribution. • Survey of health care epidemiologists • 60% felt hospital was well-prepared for pandemic • 31% reported shortages of antiviral medications • Important priorities: • Pandemic flu plan revisions • Mandatory flu vaccination for health care workers Lautenbach et al. Initial response of health care institutions to emergence of H1N1 influenza: experiences, obstacles, and perceived future needs. Clin Infect Dis 50(4):528-30. 2010.
