RESUMEN
Introduction COVID19 cancelled in-person breast cancer support in Australia. Text messages are effective at providing health support. Aim: Evaluate cost, uptake, reach and utility of a 3-month co-designed (consumers/clinicians/ researchers) lifestyle-focused text message program 'EMPOWER-SMS'. Methods Participants were recruited (Apr'20-Feb'21) via breast cancer organisations' social media and emails. Inclusion: Adults, finished active breast cancer treatment (surgery/chemotherapy/radiotherapy), lived in Australia, owned a mobile phone, sufficient English for e-consent. Exclusion: metastatic breast cancer. Online survey at baseline: Demographics and postcode (coded to Index of Relative Socio-economic Advantage and Disadvantage [IRSAD];1 least to 5 most advantaged). At 3-months: program feedback for ease-of-understanding, utility, perceived health management (5-Point Likert Scale;strongly [dis]agree), open-text feedback (coded thematically). Results Ads cost $2641. Participants' (N=845) mean age: 59±10yrs (range 30-87yrs), 48% resided in less advantaged areas (IRSAD 1-3). Survey participants (n=452) agreed/strongly agreed EMPOWERSMS was easy-to-understand (99%), useful (83%), helpful for managing health (69%), exercise (70%), healthy diet (70%). Key themes: 'feeling supported/less lonely', 'friendly reminders', 'sad it ended', 'some messages too simple'. Conclusions With low cost ($3.1/enrolment), 845 diverse participants enrolled and found it useful, overcoming support barriers during COVID19.
