Additional Info

Data Collection Instructions

Will be used for MCHP (Manitoba Center for Health Policy)

Data about COVID is sent to MCHP so please adhere to the guidelines below closely so our data is well understood.

Coding Suspected infection

If patient is a COVID suspect- combine COVID-19 (SARS-COV-2) with Observation for suspected infection NOS linked with the same number (don’t link it with any other infection code if not confirmed) Leave the code in, even if they later come up as a negative.

This should be coded on admission (if applicable) but subsequent swabs sent during the admission should not be coded as acquired diagnosis, unless the Swab is positive, then follow the usual guidelines for coding an acquired infection.

Coding symptomatic infection

COVID positive patients- combine COVID-19 (SARS-COV-2) with other appropriate diagnosis such as Pneumonia, viral, ARDS (noncardiogenic pulmonary edema)

Coding asymptomatic infection

Combine COVID-19 (SARS-COV-2) with Carrier of infectious disease, unspecified

Coding hospital acquired COVID

Add Nosocomial_infection,_NOS to what you would already code for this infection (ie might be different if symptomatic or not, or suspected etc, use the rules described elsewhere for that part).

Isolation

Enter CCI Isolation, infectious if it is happening

Infection status

  • As we do with all infections, we do the best possible to identify the bug. Sometimes we're left without a clear, laboratory identification of the bug and then we use one or another of the "wastebasket codes"
    • For example if the team believes this is likely a virus but doesn't know which one then use Virus, NOS
    • For example if the team doesn't know what kind of bug it is, but believes it is infectious then use Infectious organism, unknown

Presumed infections

If the team believes that this is COVID-19 (even without clear cut lab confirmation), then use COVID-19 (SARS-COV-2) as the organism - of course anybody seeking to do definitive analysis of all COVID-19 cases will need to obtain and use the data on confirmed cases from Cadham.

Cohorting and other location located issues related to COVID

See

When info about COVID status is found out long after locations are entered

When Reviewing a chart in MR and you find a COVID positive or COVID suspect patient that occurred BEFORE the new COVID positive/suspect wards were opened, use Service Location home ward location and use the appropriate COVID-19 (SARS-COV-2) or Observation for suspected infection NOS code.

When reviewing a chart in MR and you find a COVID suspect patient on your home ward and the patient is transferred to another location where the diagnosis of COVID positive is made, check the date/time the swab was sent. If it was sent less than 48 hours after admission code this as an Admit Diagnosis, if the swab was sent greater than 48 hours after admission code this as an Acquired Diagnosis

  • how should this be done now under PatientFollow Project / Boarding Loc ? Is it even still applicable? Likely should live under Boarding Loc instead and just be linked from here? Ttenbergen 12:24, 2020 October 29 (CDT)
    • It seems this instruction is more related to differentiating between Admit Diagnosis & Acquired Diagnosis. The note about transferring location could be taken out because what we're doing for patient follow will capture the move, but the rest of the instruction still applies I would think.

  • What are we doing for COVID recovered cases? So if MB Health considers someone to be non-infectious after 14 days, if someone is admitted to hospital >14 days from their swab date are we still coding them COVID POS? Are we using whether they are/are not isolated on admission as the deciding factor in how these are coded? Do we need a code for the recovered folks who are still needing acute care (for example patients admitted to medicine from ICU after the 14 day isolation period) Surbanski 08:21, 2020 December 10 (CST)
    • I have changed this to a Task discussion because we will need Julie and Allan for this. Could you bring it up there, please? Ttenbergen 11:26, 2020 December 10 (CST)
    • We added Post COVID-19 condition, but some of these pt are simply recovered so would not have that. Ttenbergen 09:44, 2021 February 4 (CST)
