The National Bowel Cancer Screening Program: a general practice workflow, start to finish

The National Bowel Cancer Screening Program is the single largest cancer screening initiative in Australian general practice, and most practices are not running it as a repeatable workflow. You already see the kits arrive for patients aged 50 to 74, the positive results that need follow-up, and the participants who do not return their test. Turning that into a reliable recall and reminder system means treating it as a practice process, not a series of one-off tasks.

This workflow covers what to do at each stage: eligibility, invitation, follow-up of non-responders, management of positive results, and how to prove to accreditation that you did it all. It assumes you are using Best Practice, MedicalDirector or Zedmed, and that you want to minimise manual work while meeting the RACGP Standards for recall and reminder systems.

How the National Bowel Cancer Screening Program actually works in general practice

The program mails a free immunochemical faecal occult blood test (iFOBT) kit every two years to Australians aged 50 to 74, and patients aged 45 to 49 can request one. Participation sits well below that of the breast and cervical programs, which means a large share of your eligible patients are not screening. Your practice cannot send the kit — only the National Cancer Screening Register (NCSR) can — but you can recall patients before they receive it, follow up after they receive it, and ensure those with a positive result get the colonoscopy they need.

General practice’s role breaks into four phases: prepare, invite, follow up, and manage. Each phase has a distinct workflow and a distinct recall trigger.

Phase 1: Prepare — build your eligible cohort

Eligibility is age 45 to 74, no symptoms, and not already under active investigation for bowel cancer — with the caveat that the automatic two-yearly mail-out only covers ages 50 to 74, so the 45 to 49 group depends on someone prompting them. The NCSR maintains the central register and triggers the two-yearly mail-out, but your practice management system (PMS) is where you identify who should be screening and who is overdue.

Start by pulling a list of patients aged 45 to 74 — the full eligible range, not just the 50 to 74 band the program mails to. The query needs to find active patients in that age range whose record holds no bowel screening result inside the last two years, including those with no recorded result at all. Whichever system you use, the two things that make or break this list are the date-of-birth range and how bowel screening events are coded in your practice; get those agreed before anyone builds the search. For a step-by-step on how to extract the overdue list from each PMS, see how to find every patient aged 45–74 overdue for bowel screening.

You will quickly find that age alone is not enough. Exclude patients who:

• Have a recorded total colectomy
• Are symptomatic and under investigation (code or free text)
• Have a recent colonoscopy recorded (within the last two years for average risk, sooner for higher risk)
• Have opted out of the program

This is why a coded diagnosis field beats free text: you can reliably filter out the patients who should not be screened. The cleaned list is your eligible cohort.

Phase 2: Invite — the pre-kit and kit-reminder touchpoints

The NCSR sends the kit, but patients often ignore or misplace it. A proactive practice contacts eligible patients before the kit arrives to prime them, and again shortly after it arrives to prompt action.

A practical schedule:

The NCSR notifies practices when kits are dispatched and when results are available. If your PMS is not receiving these notifications, contact your PHN or the NCSR to restore the feed — you cannot run an effective workflow without it.

For the SMS templates, use plain language. Avoid medical jargon. A message that says Your bowel screening kit is on its way. Completing it takes five minutes and can detect cancer early when it is most treatable outperforms a message that leads with incidence statistics.

Phase 3: Follow up — closing the non-responder gap

Most of the loss in this program happens here: kits are sent, and a large share are never returned. A structured follow-up protocol is the part of the workflow with the most room to move, because the alternative is no contact at all.

Start with an SMS or email at two weeks. If there is still no response at four weeks, escalate to a phone call. Reception staff can handle the first call; a nurse or GP follow-up call is reserved for patients who remain non-responsive.

Script for the phone follow-up:

1. Confirm the kit arrived and the patient understands what it is for.
2. Ask if they need help completing it. Some patients need the instructions repeated.
3. Offer alternatives: a replacement kit, or an in-practice consultation if they are symptomatic or unsure.
4. Document the outcome in the patient record, including the date, who called, and the patient’s response.

If the patient declines, code the decline and the reason. If they are planning to complete it, schedule a recall in two weeks. If they have already completed and returned it, verify against the NCSR result when it arrives.

Phase 4: Manage — positive results and surveillance

A minority of iFOBT results come back positive, and those patients are the ones your workflow cannot afford to lose. The NCSR notifies the practice and the patient. The GP’s role is to:

• Contact the patient promptly once the positive result is received
• Arrange a colonoscopy consultation within the timeframe indicated by the patient’s risk and symptoms
• Document the referral and the specialist appointment date

For patients with a positive result who do not follow through, a second-level recall is triggered: a phone call from the GP or nurse within seven days of the missed appointment, and a letter if that fails. This is a medico-legal requirement, not a courtesy.

After a positive result and colonoscopy, the surveillance interval depends on the findings, and that interval is a clinical decision informed by the colonoscopy report and the relevant guidelines — not something your recall system should assume. What the recall system needs is for the interval to be written down. Code the colonoscopy findings and the recommended surveillance interval in the patient record, with a date, so the recall fires on the interval the specialist actually advised rather than on a default two-year cycle the patient has now left.

Who should own each step in your practice

Assigning clear responsibility prevents tasks falling through gaps. A typical split:

• Reception — kit arrival logging, initial non-responder SMS, data entry of patient responses
• Nurse — phone follow-up for non-responders, patient education on kit completion, result follow-up coordination
• GP — positive result management, colonoscopy referral, surveillance interval decisions

Use a shared inbox or task list so anyone can see what is overdue and what has been done. If your PMS tracks recall status, use it rather than a parallel spreadsheet — the duplicate contacts that annoy patients almost always come from two people working off two lists.

Building the recall list you can actually maintain

The biggest obstacle practices hit is maintaining an accurate, up-to-date recall list. The list must:

• Update automatically as patients turn 50 and 75
• Exclude patients who become ineligible (colectomy, opt-out, recent colonoscopy)
• Flag patients who have not responded to the current invitation
• Track patients with a positive result awaiting follow-up

Whatever your system, the saved search needs the same logic: active patients with a date of birth in the 45 to 74 range, excluding anyone coded as opted out or as having had a colectomy, tagged against a bowel screening recall reason, and re-run on a monthly schedule rather than by hand. The scheduling matters as much as the filters — a query someone has to remember to run is a query that stops being run.

Run the recall list at the start of each month. The first working day of the month is when you generate the list of patients who are due for their two-yearly invitation or are overdue for follow-up.

How to know it is working

Track three metrics:

1. Invitation coverage — percentage of eligible patients who were invited within the two-year cycle
2. Participation rate — percentage of invited patients who completed and returned the kit
3. Positive result follow-up — proportion of positive results where the patient went on to have a colonoscopy, and how long it took

Set your own targets and then hold them steady, because the useful signal is the trend in your own numbers rather than any single figure. The one diagnostic worth knowing in advance: if participation is your weak metric while invitation coverage is healthy, the bottleneck is in the follow-up of non-responders, not in the initial invitation. The two failures need different fixes, and practices routinely spend effort on the invitation step when the loss is happening after it.

The National Cancer Screening Register publishes participation data by practice, but there is a three-month lag. For faster feedback, track your own participation monthly: number of kits sent to your patients, number returned, and number of positive results referred for colonoscopy.

Documentation for accreditation

The RACGP Standards for general practices (5th edition) require evidence that your practice has a recall and reminder system that identifies patients overdue for preventive care, contacts them, and documents the outcome.

For NBCSP, keep a simple log:

You do not need a separate spreadsheet. If your PMS can store recall notes against the patient record, that satisfies the Standard. If it cannot, export the recall data monthly and file it with your accreditation documents.

Common questions

How often should we run the NBCSP recall in our practice?

Run the main eligibility list quarterly to catch patients who have turned 50 or 75 since the last run. Run the non-responder follow-up weekly: two weeks after the kit is sent, and again at four weeks if there is no response. Positive result follow-up is triggered by the result notification and should be completed within seven days.

Can we bulk-send SMS reminders for NBCSP?

Yes, provided each message is personalised and you have recorded consent for SMS communications. Bulk SMS is efficient for the initial kit-arrival notification and the two-week reminder. Phone calls are more effective for non-responders at four weeks. Check your PMS for bulk SMS functionality, or use a third-party service that integrates with your clinical database.

What do we do when a patient says they never received the kit?

Verify with the NCSR that a kit was dispatched. If it was, request a replacement kit from the NCSR. If the NCSR confirms no kit was sent, check the patient’s address and eligibility, then request that the NCSR send one. Document the request and the date. Most patients who claim non-receipt did receive the kit but misplaced it; ordering a replacement is the correct response.

How do we recall patients who are overdue by more than two years?

Patients who are overdue by more than two years are still eligible for a kit. The NCSR does not automatically send a catch-up kit, so you need to request one. Pull a list of patients aged 45 to 74 who have not participated in the last four years, request kits for them, and follow the same workflow as for the regular two-yearly cycle. These patients are at higher risk and often respond well to a GP-endorsed invitation.
