Referral as imagined versus referral as done: mapping the referral
process for genetic counselling for Lynch Syndrome patients
3. Introduction: What is Lynch Syndrome?
• Lynch syndrome (LS) is a genetic mutation that increases
the risk of aggressive cancers, particularly colorectal
cancer (CRC), at a young age
• Cancer patients with a high risk of LS can take a genetic
test
• Carriers can undertake effective surveillance, detect and
treat cancer early and educate relatives
• Early diagnosis of LS can save lives
However …
4. The problem: referral to genetic counselling
for CRC patients with high risk of LS
• Less than half of NSW CRC patients with high risk of LS
are referred for genetic counselling and testing
Given the opportunity to improve the referral process for
genetic counselling and testing for LS where would we
begin?
5. ‘Seeing’ the problem:
mapping the referral process
“If people do not see the process, they cannot improve it.”
(Deming (1900-93))
• To improve the referral process for genetic testing for LS, we
first need to identify and visualise the process
• Process mapping creates a visual representation of the actors,
steps, and decisions involved in a process
• Cross referencing the described process with audit data
collected at various steps of the process can highlight the
process as it exists (work-as-done (WAD)) rather than as it is
imagined to occur (work-as-imagined (WAI))
6. The project aim
To co-develop at two hospitals a map of the current referral
process for genetic counselling of colorectal cancer patients
with a high likelihood of LS
7. Methods
• May – September 2015
• Two hospitals in Sydney
• Face-to-face process mapping sessions (n=6) with key
healthcare professionals involved in the referral process for
genetic counselling for testing for LS
• Implementation team meetings (n=2) with multidisciplinary
health care professionals (Medical Oncologists, Pathology
Registrars, Genetics Counsellors, Colorectal Surgeons,
Radiation Oncologists)
• Audit data collection points identified
• Electronic feedback on process map iterations

12. Results
Co-mapping the referral process has:
• Highlighted steps of the process at which data can be
collected to validate the process map and to measure the
effect of improvement strategies
• Exposed work-as-imagined (WAI) versus work-as-done
(WAD)
• Helped to create a shared understanding of the current
process
• Illuminated potential barriers for further exploration
13. Implications
Co-developing a process map with multidisciplinary stakeholders
provides a powerful tool to:
• Garner their unique knowledge of different aspects of the
process to produce a detailed representation
• Facilitate communication between team members
• Generate a shared understanding of the current referral process
(work-as-done)
• Make ‘visible’ specific challenges to appropriate referral to
genetic counselling
• Highlight potential targets for intervention to improve accuracy
and timeliness of referral
