Purpose: Referral processes for self-detected breast cancer (BC) vary in regional Aotearoa and can alter the extent to which a region can achieve the Fast Cancer Treatment indicators set by the Ministry of Health. Southern DHB (SDHB) utilises a “one stop shop”, triple assessment breast clinic with clinical review, imaging and biopsy for symptomatic BC referrals. This differs to current referral pathways in Taranaki DHB (TDHB) due to the requirement of breast imaging prior to surgical referral. Methods: All patients in TDHB and SDHB diagnosed with self-detected invasive BC between 2016 and 2020 were included (n=294). The time of presentation to primary care/referral for imaging (RI) and referral to surgery (RS) was assessed and compared to the time of first cancer treatment (FCT). Univariate regression analysis was used to assess association of ethnicity, rurality, and deprivation timeframes. Results: The average time between RS and FCT was 42.8 days (95% CI: 38.1, 47.5) in TDHB and 34.2 days (95% CI: 30.8, 37.56) in SDHB. The average time between RI and FCT in TDHB, however, was 62.5 days (95% CI: 56.8, 68.1). The average delay between RI and RS was 19.7 days (95% CI: 16.3, 23.1; range 0-157 days). With current referral pathways in TDHB 89.0% of patients are defined as having met the 62-day indicator compared to only 59.7% if referral to surgery had occurred immediately at first presentation. SDHB meets this indicator in 96% of patients with referral to surgery happening at initial consult. Conclusion: System delays exist for self-detected BC patients in TDHB. SDHB demonstrates the utility of triple assessment clinics in a regional setting for facilitating prompt cancer treatment for rural wāhine in Aotearoa.
