Description of intervention(s) / exposure
A two-arm parallel randomised control trial (RCT) will be used to test a theory based implementation approach (Theoretical Domains Framework Implementation) against a non-theory based implementation approach to improving identification of Lynch syndrome amongst colorectal cancer patients.
At each hospital, a locally employed healthcare professional will be appointed as a paid ‘Implementation Lead’ (IL) at one day per week over a 24-month period to coordinate the implementation approach and to oversee data collection. They will have a professional understanding of the LS patient pathway, and the ability to motivate other LS stakeholders to engage with implementation processes. Each Implementation Lead will participate in a 1-day training seminar by a health psychologist from the CCNSW research team in one of two approaches (theory or non-theory). CIA Taylor developed the following training toolkit and 1-day course: http://www.improvementacademy.org/tools-and-resources/abc-for-patient-safety-toolkit.html. These training materials have been refined for this study and modified according to trial arm. Those in the theory-based trial arm will be trained in the Theoretical Domains Framework Implementation (TDFI) approach. Following training, the Implementation Lead will work through the following steps at their hospital over a 24-month period:
1. Extract baseline audit data: Clinical data from surgical, pathology and FCC databases will be extracted to determine proportion of pts appropriately referred
2. Form Implementation Team: will form a team of 8-10 multidisciplinary staff involved in the LS referral and diagnosis pathway (e.g. genetic counsellors, CRC surgeons, oncologists, pathologists, nurses, admin etc)
3. Map referral process and identify targets for change: 2 x meetings to map current processes and (using audit data) identify areas for change
4. Identify barriers to change: Staff to complete 5 min questionnaire about perceived barriers & focus group to discuss and confirm main barriers (using the theoretical domains framework; TDF)
5. Generate intervention strategies: Second focus group to develop intervention strategies to address main barriers (using the theoretical domains framework; TDF)
6. Implement intervention strategies: Implementation lead (with support from CCNSW) will implement strategies over a 6mo period
7. Evaluate intervention: extract data & compare with baseline to assess change

Behaviour
Comparator / control treatment
The comparator is a non-theory based implementation approach which is distinguished only by the lack of theory used to identify barriers and to design targeted interventions, on improving clinical practice for identifying LS patients.
At each hospital, a locally employed healthcare professional will be appointed as a paid ‘Implementation Lead’ (IL) at one day per week over a 24-month period to coordinate the implementation approach and to oversee data collection. They will have a professional understanding of the LS patient pathway, and the ability to motivate other LS stakeholders to engage with implementation processes. Each Implementation Lead will be trained by a member of the CCNSW research team in one of two approaches (theory or non-theory). CIA Taylor developed the following training toolkit and 1-day course: http://www.improvementacademy.org/tools-and-resources/abc-for-patient-safety-toolkit.html. These training materials have been refined for this study and modified according to trial arm. Implementation Leads in the non-theory arm will be trained about general (non-TDF) implementation science principles. Following training, the Implementation Lead will work through the following steps at their hospital over a 24-month period:
1. Extract baseline audit data: Clinical data from surgical, pathology and FCC databases will be extracted to determine proportion of pts appropriately referred
2. Form Implementation Team: will form a team of 8-10 multidisciplinary staff involved in the LS referral and diagnosis pathway (e.g. genetic counsellors, CRC surgeons, oncologists, pathologists, nurses, admin etc)
3. Map referral process and identify targets for change: 2 x meetings to map current processes and (using audit data) identify areas for change
4. Identify barriers to change: Staff to complete 5 min questionnaire about perceived barriers & focus group to discuss and confirm main barriers
5. Generate intervention strategies: Second focus group to develop intervention strategies to address main barriers
6. Implement intervention strategies: Implementation lead (with support from CCNSW) will implement strategies over a 6mo period
7. Evaluate intervention: extract data & compare with baseline to assess change
In contrast to the theory-based trial arm, Phase 4 and 5 will not use the TDF. Barriers and solutions will instead be generated based on intuitition and tacit knowledge.

The trial is targeting the behaviour of health professionals (e.g. surgeons, oncologists, pathologists) to improve referral of patients at high risk of Lynch syndrome. For both implementation trial arms, a historical control (e.g. patients who underwent colorectal cancer resection prior to commencing trial activities) will enable assessment of referral rates before and after the trial period. Patients included in the historical control analyses will be those aged 18 years and older who underwent resection of a CRC tumour between 01/07/2016 -30/06/2018 at participating hospitals. Patient data will be extracted from relevant surgical, pathology, and FCC databases.

Outcomes
Primary outcome [1] 306306 0
The primary outcome will be the proportion of patients with risk-appropriate completion of the LS referral pathway. Clinical and referral data will be extracted from a number of sources (e.g. hospital, pathology and genetics databases) to assess whether patients at high-risk of Lynch syndrome (e.g. those mismatch repair deficient or high level microsatellite instability colorectal cancer tumours) were referred to a familial cancer clinic for consideration of germline Lynch syndrome testing.
Timepoint [1] 306306 0
Completion of the LS referral pathway within 2 months of CRC resection.
Secondary outcome [1] 348133 0
Proportion of high risk-patients who were referred to the familial cancer clinics (FCCs) (sensitivity of referral). This will be assessed via linkage of clinical and referral data from a number of sources (e.g. hospital, pathology and genetics databases).
Timepoint [1] 348133 0
Within 2 months of CRC resection
Secondary outcome [2] 348134 0

Efficacy
Statistical methods / analysis
Patients will be assigned to the baseline or the post-intervention implementation phase if they underwent surgery before or after the intervention implementation in the CRC patient referral centre, respectively. Patients will be assigned to the theory based or non-theory based implementation arms based on the assignment of the CRC patient referral centre where they underwent surgery. For each dichotomous study outcome, we will estimate the adjusted relative proportion of patients with the outcome using a generalised linear regression model with Poisson distribution, log link and generalised estimating equation (GEE) adjustment for the clustering of patients within hospitals. Covariates will be specified as time period (3-month intervals), time since intervention (3-month intervals), patient age at operation, cancer stage, and private patient status. The Quasi-AIC will be used to select which covariates to include in the final model. To account for non-independence of within-hospital outcomes, all GEE analyses will be carried out with exchangeable working correlation structures and with robust standard errors. We will carry out sensitivity leave-one-out analyses by individually excluding hospitals that accounted for more than 20% of the total patient numbers.

Summary
Brief summary
The purpose of this study is to test two different implementation approaches (theory based and non-theory based) in achieving behaviour change amongst healthcare professionals to improve identification of Lynch syndrome amongst colorectal cancer patients.

Who is it for?

You may be eligible for this study if you are a healthcare professional involved in the Lynch syndrome referral pathway. Although we will be assessing the proportion of colorectal cancer patients appropriately referred for Lynch syndrome genetic testing (based on high-risk LS tumour screening results, e.g. mismatch repair deificiency, or microsatellite instability), we will be targeting the behaviours of health professionals in this study to improve referral practices.

Study details
Participants will take part in one of two arms (theory based or non-theory based) depending on the hospital in which they work. Participants will be asked to complete questionnaires and will be involved in a series of meetings and focus-groups to map the referral pathway, identify target behaviours for change, identify barriers to behaviour change and develop intervention strategies to address those barriers. Clinical and referral data will be collected before and after the study period to assess for changes in the proportion of patients appropriately referred for Lynch syndrome genetic testing.

It is hoped that this research will increase the number of colorectal cancer patients with a high risk of Lynch syndrome who are appropriately referred for genetic counselling and testing.
