Patient Impact and Hospital Capacity The url for this measure is http://hl7.org/fhir/uv/saner/Measure/ComputableCDCPatientImpactAndHospitalCapacity. This measure demonstrates automated reporting on bed availability and use at a facility location based on CDC/NHSN reporting requirements. It is used to illustrate automation of measure reporting using the SANER Implementation guide. Frequency This measure is expected to be reported every 1 day.

Boone (mailto:kboone@ainq.com) Status draft Definitions Ventilator Any device used to support, assist or control respiration (inclusive of the weaning period) through the application of positive pressure to the airway when delivered via an artificial airway, specifically an oral/nasal endotracheal or tracheostomy tube. Note: Ventilation and lung expansion devices that deliver positive pressure to the airway (for example: CPAP, BiPAP, bi-level, IPPB and PEEP) via non-invasive means (for example: nasal prongs, nasal mask, full face mask, total mask, etc.) are not considered ventilators unless positive pressure is delivered via an artificial airway (oral/nasal endotracheal or tracheostomy tube). Beds Baby beds in mom's room count as 1 bed, even if there are multiple baby beds Follow-up in progress if staffed is less than licensed. Total includes all beds, even if with surge beds it exceeds licensed beds.

Active encounters where the encounter diagnosis is suspected or confirmed COVID-19, or a Condition of suspected or confirmed COVID-19 was created during that encounter.

Confirmed A patient with a laboratory confirmed COVID-19 diagnosis Suspected A patient without a laboratory confirmed COVID-19 diagnosis who, in accordance with CDC’s Interim Public Health Guidance for Evaluating Persons Under Investigation (PUIs), has signs and symptoms compatible with COVID-19 (most patients with confirmed COVID-19 have developed fever and/or symptoms of acute respiratory illness, such as cough, shortness of breath or myalgia/fatigue).

Hospital COVID-19 Patient Encounters Reporting
All COVID-19 Confirmed or Suspected Patients
Patients with suspected or confirmed COVID-19 in any location.
Active encounters where the encounter diagnosis is suspected or confirmed COVID-19, or a Condition of suspected or confirmed COVID-19 was created during that encounter. This includes the patients with laboratory-confirmed or clinically diagnosed COVID-19. Confirmed: A patient with a laboratory confirmed COVID-19 diagnosis Suspected: A patient without a laboratory confirmed COVID-19 diagnosis who, in accordance with CDC’s Interim Public Health Guidance for Evaluating Persons Under Investigation (PUIs), has signs and symptoms compatible with COVID-19 (most patients with confirmed COVID-19 have developed fever and/or symptoms of acute respiratory illness, such as cough, shortness of breath or myalgia/fatigue).
