Description of intervention(s) / exposure
Brief intervention name: Point-of-care clinical prompt (Prompt)

Materials and Procedures:
A point-of-care clinical prompt stating “Encourage Participation in National Bowel Cancer Screening Program” will be attached to the electronic files of eligible patients (average risk patients turning 50, 60 and 70 years of age) within a general practice. These patients represent a sample of the population who will receive a National Bowel Cancer Screening Program (NBCSP) kit during the 12-month trial period.

The prompt will remind General Practitioners (GPs) to talk to their patients about using the free kit when it arrives in the mail on or around the time of their birthday.

National Bowel Cancer Screening Program (NBCSP) patient information brochures and posters will be available for general practitioner (GP) use as hard and/or electronic copies. Each GP in the trial will also recieve a sample NBCSP kit to show to patients during the consultation.

Mode of delivery:
The prompt will be set up by general practice administration staff within the electronic files of eligible patients. The prompt will be delivered to GPs as an electronic pop-up reminder at the start of a consultation.

When an eligible patient arrives for their consultation at a practice, the prompt will ‘pop-up’ over the patient’s electronic file. The GP will then decide whether to discuss screening at that point in time or whether to ‘close’ the prompt. If the prompt is closed, it will remain as an outstanding action each time the patient attends the practice until such time as the GP marks the task as ‘performed’ by checking the relevent box.

Additional resouces including patient information brochures and a sample/demonstration kit, will be made available by the GP during the consultation.

Frequency and duration:
The intervention will be trialled over 12 months. It is estimated that a total of 1750 patients will be eligible to have the prompt associated with their electronic file within the five intervention sites. This is the maximum number of times the prompt will be acted on by GPs.

Location:
The intervention will take place in five Tasmanian general practices located within Outer Regional and Remote Tasmania (Remoteness Areas 3 and 4).

Adherence:
GP adherence to using the prompt will be determined by the number of prompts that were marked as ‘performed’ compared to the number of prompts that were not.

Behaviour
Comparator / control treatment
The control group consists of five general practices pair-wise matched with 5 intervention practices on size (number of full-time-equivalent GPs), rurality and socioeconomic disadvantage (based on location). These general practices will provide usual care, and screening participation rates will be compared to the intervention group.

Eligibility
Key inclusion criteria
General Practices: Only general practices located in Remoteness Areas 3 and 4, and identified as not participating in other University of Tasmania research, will be invited to participate.

General Practioners: All GPs within a recruited practice will be invited to participate in the study. No exclusion criteria apply.

Patients:
All active patients of the five intervention practices who turn 50, 60 and 70 during the 12-month intervention will be eligible to receive the prompt. Exceptions to this are patients identified as having a higher than average risk of bowel cancer including patients with a known personal or family history of bowel cancer, or with existing bowel conditions (e.g. inflammatory bowel disease, crohn’s disease). The NPCSP recommends individuals at above-average risk for bowel cancer should discuss screening options with their GP rather than use the free kit.
Minimum age
50 Years
Maximum age
70 Years
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
General Practices located outside Remoteness Areas 3 and 4, and currently participating in or earmarked to particpate in University of Tasmania research will not be invited to participate.

Patients outside the specified age groups and at higher than average risk of developing bowel cancer (as defined by the NBCSP) will be excluded from receiving the prompt from their GP.

Efficacy
Statistical methods / analysis
As this is a preliminary trial/pilot study, with no precedent to refer to, the sample size required to show an effect is difficult to determine. However, the number of patients who will potentially be encouraged to screen for bowel cancer as a result of the GP prompt will be maximised within the constraints of the study. Based on the number of eligible patients identified in one rural practice, we estimate we will potentially reach 1000 patients with the prompt.

Binary logistic regression will be used to model the likelihood of completing the NBCSP FOBT test among intervention versus control participants, controlling for potential covariates including age, gender, and socioeconomic status.

Time between patients being prompted by their GP and receiving the kit in the post will also be included as a covariate in the analysis.

Practice data will be used to compare NBCSP participation rates for patients during the 12 months prior to the intervention with data collected for the study period.

Data on GP use of the prompt will be analysed in terms of the proportion marked as ‘performed’ for all eligible patients who attend a GP consultation during the intervention period.
