Executive Summary
There is presently an outbreak of a coronavirus disease (COVID-19). This is a
respiratory illness with symptoms ranging from a mild cough, through to pneumonia.
Many people will have mild to moderate symptoms, with a smaller proportion requiring
hospitalization and intensive care.
COVID-19 spreads from person to person, and there is a risk that the disease may
spread in hospitals. Infection prevention and control measures, alongside public health
interventions have been shown to limit the spread of the disease.
The current outbreak has affected many countries worldwide and is considered a
pandemic by the World Health Organisation. Travel restrictions and rapid public health
responses have helped to contain the initial spread of the virus in Australia.
Information about clinical assessment and public health characteristics of COVID-19 is
available at:
https://www.dhhs.vic.gov.au/health-services-and-general-practitioners-coronavirus-
disease-covid-19
As part of the Australian government response, up to 100 private practice respiratory
clinics will be established for patients with mild to moderate symptoms.
The purpose of this document is to provide advice for acute respiratory assessment
clinics that will complement management of patients who present to the Victorian
hospital sector.

Purpose and scope of an acute respiratory
assessment clinic (ARAC)
The purpose of an acute respiratory assessment clinic is to provide safe and
streamlined assessment and management of patients who present to hospital systems
with risk factors for, or concern that they may have COVID-19.
For most patients, COVID-19 will present as a mild respiratory illness, and clinical
assessment can be safely managed in general practice.
For some patients with risk factors for, or who present with more serious illness,
assessment close to a hospital facility is most appropriate.
The function of ARACs is to:
    1. Allow nearby emergency departments to function as usual by deferring patients
       presenting for COVID-19
    2. Provide early cohorting of patients away from the rest of the patient population,
       to prevent nosocomial transmission
    3. Concentrate clinical expertise
    4. Provide healthcare worker testing capabilities.
During periods of significant surge, these centres may also assist general practice in
meeting the needs of the population (including the testing of healthcare workers).

Clinic location and design
The design of an ARAC is based on the principles of maximizing infection prevention
and control, and adequate distancing of patients1-4.

Location
The preferred location of ARACs for hospitals is close to, but not inside emergency
departments.
The benefits of this co-location are to:
• Allow emergency departments to safely divert into another model of care
• Provide streamlined admission for patients requiring admission
• Limit secondary transfer of patients from ARACs to hospitals using ambulance
  services
• Utilise existing governance, and operations frameworks within an organisation.
Within these confines, the selected area should be:
• Low transit, well ventilated, and secure
• Minimise the distance patients travel through other clinical areas to access the
  ARAC
• Make use of existing infrastructure where this is available
• Provide easy deferment of unwell or unexpectedly deteriorating patients.

Principles of design
The principles of design of clinics is to:
    1. Control and limit access to patients and a potentially contaminated area.
    2. Provide an early opportunity for staff to don PPE before entering areas with
       potential contamination.
    3. Concentrate clinical care and expertise into a designated area.
    4. Maximise ability to manage high or rapidly changing patient numbers.
    5. Provide a one-way flow of movement, so that patients with little risk of disease
       are separated and discharged early.
    6. Provide safe disposal of waste.

           storage for PPE, staff logbook.
           Patient registration.
           Design: situated after entrance where PPE is adopted. Parallel ‘lanes’ of
           assessment can be adopted if there is a high caseload.
           Purpose: A staging area to assess vital signs and to triage patient, and a
 2.        protected location of work for triage nurses and clerks.
           Equipment: computer and label printer for clerks, electronic or paper
           based screening forms if these have been adopted by your institution,
           equipment for physiological triage of patients (blood pressure cuffs pulse

 3.        Patient assessment waiting area

Page 8                       COVID-19: Guidelines for acute respiratory assessment clinics, 12 March 2020
Design: Seat patients in designated areas with a minimum 1m space
              between them, unless they are a cohort (family) in which case they can sit
              together
              Purpose: Provide space for treating clinicians to undertake initial
              assessment.
              Equipment: chairs for waiting patients, water for waiting patients.
              Biological sampling (non aerosolised)
              Design: Ideally a room that has a closed door, or a well ventilated area with
              physical separation from patient assessment waiting area.
 4.           Purpose: take COVID swabs and perform other biologic sampling
              procedures as indicated.

Patient flow algorithm
The next page shows an example of a patient flow matrix that can be adapted for your
service, according to your local resources. This can either be circulated as an electronic
or paper document, or placed on a white board.

Because case definitions (and therefore indications for testing) change frequently, and
maintenance of a ‘live’ version of this matrix requires continued vigilance regarding
government communication.

DHHS and Safer Care Victoria are working to have a centralised and frequently update
version of this document suitable for statewide use.

Staff training and PPE training requirements
The expectation of staff working in the ARAC is that they
   1. Undertake daily review of the case definitions and changes in clinical
      management flowcharts.
   2. Understand the symptoms and relevant epidemiology of COVID-19
   3. Are compliant with IPC policy

Regarding PPE, At a minimum, all staff who work in the assessment clinic should:
• Have watched relevant PPE donning and doffing videos
• Been fit tested for a N95/P2 mask.
• Renew training once a year, or following a period of more than 6 months of non-
  clinical work.

The following links on PPE resources are provided by the Department of Health and
Human Services:
How to put on and fit check a P2 respirator (PDF)
How to put on your PPE (PDF)
How to take off your PPE (PDF)
Further resources will become available with time, and released via:
https://www.dhhs.vic.gov.au/health-services-and-general-practitioners-
coronavirus-disease-covid-19

The following incidents should be notified to the psychological and staff health lead.
   1. Notification of a failure to wear appropriate PPE in an assessment clinic.
   2. Suspected breach of PPE during undertaking of aerosolosing procedures.
