The purpose of these COVID-19 Interim Guidelines is to provide short-term advice to manage the risks associated with COVID-19 in the community and to protect patients and St John WA staff from potential exposure whilst maintaining the highest possible standards of clinical care to the community of Western Australia.


All Clinical Practice Guidelines not addressed in this document remain unchanged and still apply in full. Staff should ensure that they stay up to date with the latest information regarding COVID-19 on Connect.

This update is provided in the setting of very low penetration of COVID disease in Western Australia and zero or close to zero community transmission.

GTN spray is considered a critical list item due to limited availability.

Crews should allow the patient to administer their own GTN spray wherever possible.

Allow the patient to self-administer the GTN spray; stand clear and wait a minute before approaching the patient.

If you have to use SJA supplied Glyceryl Trinitrate (GTN Spray), assess whether it can be reused and wipe with Clinell wipe after use. Discard the MDI if the patient is very unwell or highly symptomatic of infectious respiratory condition.

Both the officer and the patient should perform hand hygiene after use.

If GTN is deployed in a suspected/confirmed COVID patient with significant respiratory symptoms, discard the device after use.

Note: If administering St John supplied medication, crews are NOT to leave the remainder of the medication with the patient. This is a violation of the St John WA poisons licence and the Medicines and Poisons Act 2014.

No vehicle should be considered non-operational due to not having GTN available; if GTN is not available step up to the next level of pain relief.
