Background: Breast cancer is the most commonly diagnosed women’s cancer with 2.3 million new global cases diagnosed in 2020. The global rise in survivorship has resulted in a significant health and economic burden on society. Breast cancer survivors report being overwhelmed physically and emotionally with treatment adverse effects. Recommendations include self-management support and personalised follow-up to meet patient needs. Persistent post-surgical pain (PPSP) is the most common negative consequence of breast surgery, often relating to inadequate acute post-surgical pain management. An unintended consequence of day surgery is reduced post-operative pain monitoring. There is a need to ensure appropriate support and pain monitoring alongside preparation, behavioural change and expectation management. Web-based interventions (WBI) could be a potential solution. A mixed-methods approach was used to develop a WBI to capture patient self-reported post-operative symptoms and provide individualised self-management advice. Methods: An audit and service evaluation revealed a 46% PPSP rate and identified opportunities where advice could support improved self-management. Developing the WBI (ePainQ) comprised a scoping review, systematic review, and development study with all results informing the development of ePainQ. ePainQ comprised two parts; a website containing supportive information and a post-operative symptom questionnaire. Intervention questions included pain, swelling, infection, functionality and QoL. Advice was generated for each question with different levels, based on CTCAE grading agreed with clinicians. A feasibility study prospectively tested ePainQ for acceptability, usability and perceived usefulness. Feasibility study aims were assessing uptake, retention, follow up and completion rates and acceptability of ePainQ. Study arms: usual care (cohort) or intervention (ePainQ). Intervention: daily online symptom questionnaire for 2 weeks commencing the day after surgery. Participants received immediate advice based on the severity of the reported symptoms, either self-management advice or in cases of clinical concern, advice to contact the hospital team. Reports were immediately available to HCPs as ePainQ was linked to the electronic patient record. Data collection: baseline, 2 weeks, 3 and 9 months post-operatively. Outcome measures: EORTC C30, and BR23, EQ-5D, HADS and BPI. Patient Activation was measured at baseline and 9 months. Results: 69 patients recruited over 8 months; 60 intervention and 9 cohort. Mean age: 57.7yrs (SD 9.8; range 38-82). Recruitment rate was 63%. IT issues prevented 12/60 using ePainQ but engagement of the 48/60 active participants was 89.6%. 40/48 completed a usability scale in which • 97.5% highlighted ePainQ as easy to use • 95% reported not needing any technical support • 90% felt very confident using ePainQ Outcome measures: 69/69 (100%) completion at baseline and 2 weeks. No active withdrawals with 13/69 passive withdrawals by 9 months. 67 participants (97.1%) consented to an interview invite with 14/67 interviews conducted. Participants were a mix of compliance rates to be reflective of the study and capture both positive and negative feedback. Feasibility study results demonstrated that ePainQ was perceived to be simple, easy to use and not requiring much learning to use effectively. All pre-set criteria for progression to a phase III RCT were met. Conclusion: ePainQ was designed in response to patient identified needs. The feasibility study established that ePainQ was accepted, used, and liked by participants who interacted with it. Even participants with limited use felt they had benefited from the advice. Results demonstrated patient positivity towards ePainQ suggesting recruitment rates could be increased if research capacity was improved and higher retention rates if IT issues were resolved and daily reporting duration was slightly reduced.
