With an increase in breast cancer survivors (BCS) in Singapore, the current oncologist-centric survivorship model will not be sustainable to respond to the rising demand of survivorship care services. To meet the long-term healthcare needs of Singaporeans in a sustainable manner, the investigators propose to pilot a breast cancer survivorship inter-professional community (BASIC) care model for cancer survivorship. This pilot study aims to assess the feasibility and acceptability of this care model for implementation among BCS and healthcare providers. The investigators hypothesize that the BASIC model is feasible and acceptable to be evaluated on a larger scale. This new follow-up model can potentially reduce waiting times in tertiary centers without compromising quality of care, directly benefiting participants through more efficient follow-up sessions.

In Singapore, breast cancer accounts for approximately 30% of all new cancer cases. With an overall 10-year age-standardized survival rate of 50%, it is estimated that 900 BCS will require dedicated cancer survivorship care in Singapore annually. However, the current oncologist-centric survivorship model adopted in Singapore will not be sustainable to respond to the rising demand for survivorship care services. This inability to cope with the growing demand poses a major challenge to the health system and accentuates an emerging need for an alternative evidence-based care model to support BCS and healthcare providers in achieving efficient and effective cancer survivorship care.

The American Society of Clinical Oncology (ASCO) advocates a collaborative survivorship care model involving the transition of cancer survivors from specialist to primary care setting via a risk-stratified approach. While the proposed collaborative model is promising and appealing, its feasibility and applicability in the local Asian setting considering cultural and socioeconomic factors is unknown. Furthermore, two major gaps exist: (i) there is a lack of comprehensive evaluation of structural factors in care coordination and clinical outcomes determination; and (ii) the potential of community pharmacists in cancer survivorship care is not maximized.

The main objective of the study is to assess the feasibility and acceptability of the BASIC care model for implementation amongst BCS and healthcare providers. The secondary objective addresses the effectiveness of BASIC model by providing robust parameters estimation for the physical symptom distress burden and quality of life outcome measures that will be used for sample size calculation in the eventual main trial.

This will be a pragmatic, randomized, controlled, pilot trial conducted at the National Cancer Centre Singapore (NCCS), participating SingHealth polyclinics and Watsons community pharmacies over a period of 2 years. Participants will be randomized into the multidisciplinary collaborative care arm or attentional control arm in a 1:1 ratio, stratified by the absence versus presence of comorbidities. In the multidisciplinary collaborative care arm, participants will experience a 12-month cancer follow-up schedule via a shared-care approach. In the attentional control arm, participants will continue with usual care.
