Anthrax exposure represented by one of two codes in either a Condition or Observation FHIR R4 resource. The parameter Exposure_Look_Back_Period controls how far back to filter potential exposure resources. Default is 60 days. 2. Asymptomatic represented by SNOMED-CT code 84387000 in an Observation FHIR R4 resource. Asymptomatic Observation must occur on the same day or after the exposure date. 3. Existing antimicrobial Rx found by querying MedicationRequest and MedicationStatement FHIR R4 resources. 4. Administration of the Anthrax vaccine represented by one of the sequential SNOMED-CT procedure codes. This is how past doses are discovered via querying for Procedure FHIR resources. 5. The recommended spacing between subsequent doses of the vaccine is controlled by the parameter Spacing_Between_Vaccine_Doses, which has a default value of two weeks. A patient undergoing Anthrax PEP will only be recommended their next vaccine dose if two weeks have elapsed since their last and if they have not received the recommended allotmant of three doses. 6. Pregnancy can be represented as an Observation or a Condition FHIR R4 resource. Both types of resouces are examined to determine if the patient is pregnant. 7. Allergies are discovered by querying for AllergyIntolerance FHIR R4 resources that contain ingredient/substance codes for any of the potentially recommended PEP treatments. This includes the antimicrobials, the vaccine, and latex. 8. Alerts are communicated via either DetectedIssue or Flag FHIR resources. 9. Aside from the alerts, the main output of this CDS is an order set. It is represented via FHIR R4 resources (ActivityDefinition and PlanDefinition). 10. This CDS outputs various FHIR resource objects. For the purposes of local FHIR references, it is assumed all generated FHIR resources will be returned in a single FHIR bundle. */ // Data model using FHIR version '4.0.0' // ------------- LIBRARIES

After exposure to aerosolized B. anthracis spores, antimicrobial therapy should be initiated as soon as possible. Ideally, the first dose of vaccine should be administered within 10 days. ACIP recommends a post exposure regimen of 60 days of appropriate antimicrobial prophylaxis (covered previously) combined with 3 subcutaneous doses of AVA (administered at 0, 2, and 4 weeks post exposure) as the most effective protection against inhalation anthrax for previously unvaccinated persons aged ≥18 years who have been exposed to aerosolized B. anthracis spores. In general, the peak serologic response to anthrax vaccine occurs 10–14 days after the third dose. (Wright, J.G et al., Morbidity and Mortality Weekly Report, July 23, 2010 / 59(RR06); 1-30). Additionally, the Advisory Committee on Immunization Practices subsequently reviewed all safety data available as of March 2008, including the final results of a retrospective study, and concluded that AVA is safe to administer to anthrax-exposed women during pregnancy. In the setting of an anthrax event that poses a high risk for exposure to aerosolized B. anthracis spores, pregnancy is neither a precaution nor a contraindication to vaccination. Pregnant women at risk for inhalation anthrax should receive AVA and antimicrobial drug therapy regardless of pregnancy trimester (Meanye-Delman D et al., Emerg Infect Dis, 20(2), 2014).' // Purpose to be used in all ActivityDefintion resources generated by this library define ActivityDefinitionPurpose: 'Provides clinicians with information for quickly assessing individuals exposed to anthrax unrelated to occupational exposure, for example in bioterrorism events, and provides the recommended post-exposure prophylaxis (PEP) regimen for asymptomatic patients.

Contact with and (suspected) exposure to anthrax
Provides clinicians with information for quickly assessing individuals exposed to anthrax unrelated to occupational exposure, for example in bioterrorism events, and provides the recommended post-exposure prophylaxis (PEP) regimen for asymptomatic patients. Includes immediate treatment with antimicrobials and vaccine and follow-up administration of subsequent vaccines to complete the recommended 3-dose vaccination series.
Intended for use by clinicians caring for individuals ≥18 years of age in an outpatient setting.
