Risk assessment matrix: traffic light system

Published 2 December 2021

The Royal New Zealand College of General Practitioners risk matrix was created in 2020 and is an adaptation of one developed by occupational health physicians from the National Framework for the assessment of staff at work. 

The matrix was specifically designed to allow primary care doctors to assess the risks associated with COVID-19 for themselves, their colleagues, and their staff.  It was also intended to be used as the basis for discussions with patients who, although not in clinical roles, might find themselves exposed to COVID-19 in their workplaces.

How to use the matrix 

  • This is an advisory based on risk assessment and should be read alongside this explanation.
  • The first two columns relate to general practice staff with close clinical contact with symptomatic (red stream) and asymptomatic (green stream) patients
  • The last three columns are designed to start a discussion with patients in general.
