COVID-19 Outbreak Update

Trillium Health Partners’ (THP) top priority is the safety of our patients, people and the community. As we continue to see community spread of COVID-19, THP remains vigilant and is actively preparing measures to respond to additional cases and outbreaks.

What is a COVID-19 outbreak?

In accordance with the Ministry of Health, a COVID-19 outbreak is declared when two or more patients and/or staff within a specified area (unit/floor/service) with confirmed COVID-19 have been identified within a 14 day period, where both cases could have reasonably* acquired the infection in the hospital. Examples of reasonably having acquired an infection in hospital include:
no known source of infection outside of the hospital; or having been admitted for 5 or more days before symptom onset (based on the median incubation period of the virus).  

As part of our Pandemic Response action plan and in alignment with the hospital’s infection prevention and control guidelines, we have implemented a number of initiatives. These include:

  • Enhanced screening for all individuals entering our hospital, including staff
  • Temporary no-visitor policy as of March 20, 2020
  • Postponed elective and non-emergency surgeries
  • Opening of COVID-19 Assessment Centres (three to date)
  • Adoption of Public Health Ontario guidelines for Droplet Contact Precautions for potential COVID-19 patients
  • Designated units for COVID-19 patients
  • Continued health care worker education and demonstrations for appropriately using personal protective equipment during this pandemic

When an outbreak is declared on a unit, additional measures are put into place. These include:

  • Closing the unit to any new admissions
  • Transferring COVID-19 patients to designated units
  • Putting existing unit patients on Droplet/Contact Precautions
  • Monitoring and testing of staff, professional staff and patients regardless of symptoms
  • Contact tracing for possible exposure
  • Limiting staff members who normally work on multiple units to work on one unit only
  • Enhanced cleaning on the unit, and increased education on the use of personal protective equipment, washing of hands and physical distancing
  • Increased hand hygiene audits

Total COVID-19 Outbreaks

Three health care workers on 2B/1 COVID-19 Unit at Mississauga Hospital tested positive for COVID-19 between April 29, 2020 and May 9, 2020. Two of the three cases have a likely epidemiological link, and have acquired from hospital and community. In consultation with Peel Public Health, an outbreak has been declared.

Two health care workers in the Emergency Department (ED) at Mississauga Hospital have tested positive for COVID-19 between May 10 and May 15. Although our investigation and contact tracing does not show a known association between these cases, out of an abundance of caution and in consultation with Peel Public Health and the Ministry of Health we are placing this unit on outbreak to ensure the safety of all staff, professional staff and patients.

As increased personal protective equipment and heightened protective measures are routinely being used with patients in the ED, through contact tracing, at this time we have determined that no ED patients had high risk exposure during this period.

The ED remains open and safe for patients and health care workers. We are here to serve the community and urge anyone in need of emergency care not to delay seeking medical attention.

Guided by infection prevention and control best practices, rigorous processes are in place to protect patients in the ED including:

  • As per normal processes, all patients are supplied with masks at the entrances and must wear them in the hospital at all times
  • All ED patients will now be placed on Droplet/Contact Precautions which means health care workers will wear gowns, gloves, procedure mask and face shield when interacting with patients. This will ensure health care workers and patients are safe.
  • Increased hand hygiene and personal protective equipment audits
  • Screening of everyone at ED entrances
  • Placing any ED patients who meet the clinical criteria for COVID-19 into separate spaces including the COVID-19 assessment centres and units dedicated exclusively to serving patients with COVID-19
  • Regular cleaning and various measures to encourage physical distancing – including an expanded ED footprint to allow space for more physical distance.
