Pre-Event Planning Evaluating your facility
Plan of Action • Emergency management plan • Mitigation • Preparedness • Response • Recovery
Identifying a Problem • Most common features of an outbreak caused by a bioterrorism agent • Influenza-like illness • Viral exanthem: rash/fever • Gastrointestinal complaints
Surveillance Methods • Databases • Mainframe systems • Admissions • Emergency department • Microbiology
Surveillance Methods • Mainframe systems • Laboratory • Pathology • Radiology • Pharmacy
Surveillance Methods • Access to system • Report distribution • Computer access • Patient electronic medical record • HIPAA concerns ?
Confirming the Diagnosis • Coordination of surveillance plan • Review of symptoms • Gathering data • Communication with internal and external resources
Facilities/Environmental • Isolation Rooms • Negative Pressure • Alternatives • Transportation Routes • Lockdown • Disinfectants • PPE
Laboratory Support • Level of involvement • Level A: Initial work- r/o BT agents • Level B: County/state- agent confirmation • Level C: Large state lab/ advanced labs • Level D: CDC/DOD labs
Laboratory Support • BSL levels • 1: General office • 2: Biosafety cabinets • 3: Negative airflow • 4: “Moon suits”
Specimen Collection • Collection • Preparation • Media • Preservation • Shipping • Notification
Febrile, Vesicular Rash Illness Algorithm for Evaluating Patients for Smallpox
Smallpox Diagnosis • Traditional confirmatory methods • Electron microscopy of vesicle fluid • Rapidly confirms if orthopoxvirus • Culture on chick membrane or cell culture • Slow, specific for variola • Newer rapid tests • Available only at reference labs (e.g. CDC) • PCR, RFLP
Lab Methods for Confirmation of Orthopoxvirus Diagnosis • PCR related methods for DNA identification, (e.g., real-time PCR) • Electron microscopy • Histopathology • Culture • Serology • Antigen detection (IFA, EIA ag capture) • IgM capture • Neutralization antibodies • IgG ELISA
Negative Stain Electron Microscopy Vaccinia
Specimen Collection • Vaccinia and variola specimen collection essentially the same • Check CDC website for: • Recent updates in orthopox specimen collection specifics • Appropriate infection control practices • Shipping criteria • Laboratories • www.bt.cdc.gov/agent/smallpox/ response-plan/files/guide-d.pdf
Specimens for Vaccinia-Related Disease: Vesicular Rash • Lesion ‘roofs’ and crusts • Vesicular fluids: • Touch prep • EM grid • Biopsy • Serum • Others (e.g., CSF)
Specimen procurement/handling • By recently successfully immunized person • Appropriate PPE (gowns, gloves, mask, protective eyewear) • Open vesicle with blunt end of blade • Collect with cotton swab • Place swab into sealed vacuum blood tube • Place tube in larger jar, tape lid
Handling VHF Specimens • Sample for serology - 10-12 ml • ship on dry ice • Tissue for immunohistochemistry • formalin-fixed or paraffin block • ship at room temperature • Tissue for PCR/virus isolation • ante-mortem, post-mortem; ship on dry ice • Ship serum cold or on dry ice in a plastic tube Centers for Disease Control and Prevention
Yersinia pestis:Specimen Selection • Specimen selection is important • Bubonic - bubo - lymph node aspirate • Septicemic - blood - Obtain three sets 10-30 minutes apart • Pneumonic • Sputum/throat • Bronchial washings Centers for Disease Control and Prevention
Yersinia pestis:Specimen inoculation • Inoculate routine plating media and make thin smear for DFA • Use Wayson only if DFA is unavailable Centers for Disease Control and Prevention
Laboratory Confirmation • By State Health Dept., CDC and Military labs- • Antigen detection • PCR • IgM enzyme immunoassay • Immuno-staining
Level A Lab ProceduresYersinia pestis • Gram stain • Wayson stain • Growth characteristics on agar • Growth characteristics in broth Centers for Disease Control and Prevention
Yersinia pestisGram stain • Small, gram-negative bipolar-stained coccobacilli Must confirm by DFA and mouse inoculation Centers for Disease Control and Prevention
Most likely Acinetobacter Actinobacillus H. aphrophilus Bordetella spp. Pasturella spp. Least likely DF-3 Brucella spp. Francisella spp. Gram Negative Coccobacilli
Level A Lab Procedures Francisella tularensis • This is a dangerous, highly virulent organism and it should not be manipulated at the bench, but under a controlled environment • Gram stain • Growth characteristics in broth • Growth characteristics in agar Centers for Disease Control and Prevention
Transportation Mission • Organize and coordinate the transportation of all casualties, ambulatory and non-ambulatory • Arrange for the transportation of human and material resources to and from the facility
Anticipate Transportation Needs: • Transfer agreements with lower levels of care: • Which patients? • What facilities? • How…what means of transportation?
Anticipate Transportation Needs: • Transporting discharged patients (or getting family members to pick them up) • Limited or no access to facility • Difficulty contacting families • Secure private ambulance/cabs for discharged patients
Anticipate Transportation Needs • Plan for transportation of staff and supplies to and from your organization: • Off sight gathering locations: • Private vehicle vs. group (bus/van) transportation • Non essential employees? • Housekeeping
Anticipate Transportation Needs • Provisions • Agreements in place to have vendors send supplies without actual request • Need for identification system of suppliers to pass through police or security checkpoints
Transportation • Utilize personnel from labor pool as patient transporters • Assemble stretchers and wheelchairs in proximity to ambulance off loading and triage area • Identify transportation needs of `walking’ decontaminated or non-injured individuals
Communications Mission • Organize and coordinate internal and external communications • Act as custodian of all logged/documented communications
Anticipate Communication Needs: • Provisions for normal system overloaded or inoperable: • Telephone • Page • Cellular • Fax • Alternative arrangements: • Telephone trees • Pay phones • Walkie-talkies
Anticipate Communication Needs: • Organized runner or messenger system: • Area layout maps • Established communications with local emergency medical services or management agencies • Plans to keep staff informed
Internal Communication • Systems and equipment • Train staff to repair equipment • Availability of replacement parts • Telephone lines buried, marked and protected
Internal Communication • Keep written records • Radio transmitter/receivers equipped to operate on multiple frequencies • Potentially use closed circuit TV or broadcast one-way messages
Internal Communications:Patient Records • Updating and keeping track of patient records essential • Triage tags • Medical records • Registration • History • Treatment
Communications:Staff Information • Frequent communications of accurate information • What has happened • How many patients to expect and when • How organization will help meet needs • Recognize healthcare workers’ needs to contact families • Call trees • Designated phone number
External Communications: • Establish communication lines with community and national disaster agencies • Employees, medical staff and volunteers • Family members, friends and visitors • Community office of emergency management
External Communications: • Law enforcement or military • EMS dispatch/services • Public utilities • Radio operations • Public safety communication services • Health Department
