Track 1 Care Coordination
Details of this track are included in the following confluence page:
Track 1 Care Coordination
Track 2 Multiple Procedures
Background and Objectives:
Aim to capture details around related and unrelated surgeries (procedure) that are performed by more than one surgeon on a patient within a single anesthesia timeframe and single visit to the operating room.
4 month-old ex-23 week gestation male infant with severe bronchopulmonary dysplasia (BPD), chronic respiratory failure (ventilator-dependent), gastroesophageal reflux (GER), subglottic stenosis has multiple surgeries performed while under general anesthesia. Procedures include (1) tracheotomy, (2a) Nissen fundoplication, (2b) gastrostomy tube (g-tube) placement, (3) circumcision, (4) bilateral hernia repair. The otolaryngologist performs the tracheostomy (+/- bronchoscopy) while the general surgeon performs the remaining procedure, some of which are related, some are not.
Questions to address:
How are these procedures recorded using existing resources?
Under a single anesthesia encounter?
How should this be represented for the Procedure Progress Status?
Practitioner(s) - general (pediatric) surgeon, otolaryngologist, anesthesiologist, neonatologist (or PICU attending)
Procedure(s) - gastrostomy tube placement, Nissen (gastric) fundoplication, circumcision, bilateral herniorrhaphy
Procedure.performer - general (pediatric) surgeon, otolaryngologist (is anesthesia considered part of this procedure or is it distinct?)
Procedure.category - surgical procedure
Procedure.code - many... https://www.hl7.org/fhir/valueset-procedure-code.html
Procedure.partOf - for components of a procedure (med adminstration, IV placement. etc...)
In Operating Room
A patient is in the Operating Room.
The patient is prepared for a procedure.
The patient is under anesthesia.
The patient has open incision(s).
The patient has incision(s) closed.
In Recovery Room
The patient is in the recovery room.
(may use CareTeam for providers)
(may consider Encounter for grouping procedures/anesthesia)
Track 3 Complex condition track: to test use of Condition + observations vs Condition profile
Stephen Chu / Rob Hausam / Jay Lyle
Background and Objectives:
For complex condition such as CoVID19, there is a need to represent and share extensive amount of information to help clinical decision making about how best to manage patients with such condition. In addition the diagnostic label of the condition, information including presence and/or absence of certain presenting features will need to be capture. The question of whether the FHIR Condition resource should be extended or profiled to accommodate such requirement has been raised.
The purpose of this track is to test whether the presence and/or absence of presenting features (e.g. signs, symptoms) should be represented in FHIR Observation resource and referenced by the Condition resource; or from information management perspective, extending the FHIR Condition resource is a better option.
SARS-CoV-2 Disease (aka SARS-CoV-2 Infection; COVID19 Disease)
fever, chills, muscle ache, fatigue
runny nose, dry cough, pneumonia, hypoxaemia or hypoxaemia without respiratory distress (silent hypoxaemia), acute pulmonary oedema, acute respiratory distress, respiratory failure
hyposmia or anosmia (loss of smell)
ageusia (loss of taste)
GI symptoms such as: nausea, vomiting, abdominal pain, diarrhoea
cytokine storm/over-reacting immunologic responses causing: endotheliitis, activation of coagulation pathways with potential development of disseminated intravascular coagulation (DIC) and deregulated inflammatory cell infiltration
atypical Kawasaki disease like symptoms
Storyboard 1 - * Patient Presenting at COVID Clinic /Drive Thru clinic/testing center*
Storyboard 2 - Patient Presenting at ED -
Scenario - A 62-yo female patient, ex-smoker (stopped 5 years ago) with medical history of ischaemic heart disease and COPD was taken to the ED by ambulance with flu like symptoms, increasing shortness of breath and hypoxaemia. Patient had no recent travel and no known contact to confirmed or suspected COVID positive persons.
On examination, patient was febrile (Temp 40C/104F), HR 107/min, BP 158/87, RR 32/min, SpO2 88% on 2L/O2. Spot BSL 200 mg/dL (11.1 mmol/L). Patient complained of tightness of chest, cough with yellowish sputum, headache, nausea, generalised ache, chills. Patient denied loss of taste and smell, and digestive symtpoms. Moderate wheezing sound on auscultation on both sides, there were also bilateral basal crackles.
White blood cell (WBC) count was 12.49 x 1012/liter, whereas lymphocyte count decreased to 0.4 x 109/liter and the differential to 5%. Chest CT showed bilateral ground‐glass opacities in the upper and middle lobes with a rounded morphology. Naso-pharyngeal swabs were taken for RT-PCR test.
The patient's condition soon deteriorated with SpO2 dropping significantly despite oxygen therapy. Patient was intubated, ventilated and transferred to ICU within an hour of arrival at ED.
Storyboard 3 - Patient Admitted to Hospital -
Scenario - A 37 yo male patient diagnosed with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spent 2 weeks in ICU and is discharged to a respiratory ward for continuous management.
COVID19 complications experienced by this patient included:
CT scans of the lungs showed interstitial abnormality in both lower lobes and rapidly progression to fibrosis.
Patient also complaint of chest pain. EKG showed ST-segment elevation on. His cardiac biomarkers were elevated (troponin T >10ng/mL, NT-proBNP [N-terminal pro-BNP] >21 000 pg/mL). An echocardiogram noted left ventricular dysfunction (ejection fraction 27%, left ventricular end diastolic diameter 5.8 cm)
Storyboard 4 - Asymptomatic/pre-symptomatic persons and person with non-specific symptoms tested for COVID19 -
An 11 yo male child complained of sore throat and runny nose. The child's mother call the family Primary Care Provider (PCP) to seek medical advice. The PCP recommended that the family of 4 to be screened for COVID19 at the family's local COVID19 drive through test clinic. Nasal pharyngeal swabs were taken from all 4 for RT-PCR test. The clinic nurse also took health history of each member and completed the CDC COVID19 PUI form.
Father: age 41, reported no COVID19 symptoms, has medical history of asthma, medication: a corticosteroid and a long-acting beta2 agonist (Seretide MDI 125/25 – 2 puffs twice daily). RT-PCR test result: negative
Mother: age 42, reported no COVID19 symptoms, no history of chronic condition, RT-PCR test result: positive
Child 1: eleven years old, complained of sore throat and runny nose when woke up in the morning, no other complaints, two episode of acute otitis media in the past 3 years with no recent recurrence. RT-PCR test result: negative
Child 2: nine years old, no COVID19 symptoms, no history of chronic illness. RT-PCR test result: negative
Family was notified of the test results and advised to self isolate at home, each in a separate room at home.

Track 4 Condition vs. Clinical Impression: Using Immunization Status as a test case
Note - this track will not be tested at the September 2020 Clinician-on-FHIR event. But the contents will be developed in preparation for future event (possibly January 2021?)
Rob Hausam/Stephen Chu/Mike Padula (will be adding more content here)
Background and Objectives:
CoVID19 and a number of other communicable diseases raise the question of how best to model and represent and share data/information about a person's immunization status. This goes beyond a simple capturing and sharing of laboratory data which include the presence or absence of neutralising antibodies to the infective agents. It also include vaccinations given and as well as clinical evaluation of all relevant information to determine the immunization status of an individual.
The objective of this track is to test the adequacy and suitability of FHIR Condition or ClinicalImpression resources in modelling and sharing immunization information about an individual.
