From small steps to big impact: what we learnt from the National Bowel Screening Programme

Area of Science:

• Public Health
• Health Services Research
• Preventive Medicine

Background:

• The National Bowel Screening Programme (NBSP) in Aotearoa New Zealand has undergone a lengthy 26-year development process.
• International evidence supported bowel screening efficacy prior to 2000, necessitating country-specific adaptations.
• Numerous initiatives to enhance healthcare delivery preceded the NBSP, contributing to systemic improvements.

Purpose of the Study:

• To describe the lessons learned during the 26-year implementation of the National Bowel Screening Programme in New Zealand.
• To highlight challenges and obstacles encountered, including the need for a pilot study and IT system development.
• To assess the programme's success in terms of safety, early diagnosis, and equitable participation.

Main Methods:

• A retrospective analysis of the 26-year journey of implementing the NBSP.
• Incorporation of lessons learned from a pilot study and ongoing adjustments.
• Involvement of multidisciplinary teams, General Practice, and global experts.

Main Results:

• The programme has demonstrated safety and effectiveness in the early diagnosis of cancer.
• Systemic improvements in healthcare delivery were achieved through pre-programme initiatives.
• Challenges included delays in IT system development and a persistent gap in equitable participation for Māori and Pacific peoples.

Conclusions:

• The NBSP's implementation journey offers valuable lessons for future public health initiatives.
• While successful in cancer diagnosis, achieving equitable participation requires further attention.
• Avoiding simultaneous use of disparate IT systems is crucial for efficient programme delivery.
