How We Do It: A Scalable, Data Driven, Student Let Model for Surgical Widening Participation

• OpSurg is the first UK student led surgical outreach programme to combine high volume delivery with systematic demographic and perceptual evaluation. • A single 30 minute in timetable session produced large immediate gains in surgical knowledge and career interest. • The programme primarily reached pupils without medical family backgrounds, directly addressing socioeconomic inequity in access to surgery. • Embedded real time evaluation allows continuous refinement and generation of publishable education data. • The OpSurg model is low cost, scalable and readily transferable to other institutions. Pupils from non selective state schools remain underrepresented in surgery, yet widening participation efforts rarely focus on socioeconomic background. There is little evidence on large scale outreach delivered in school hours with built in evaluation. To address this gap, Operation Surgery (OpSurg) was created as the first student led programme in the UK to combine high volume delivery with systematic demographic and perceptual analysis. OpSurg delivers a 30 minute session on surgical careers during compulsory school hours. Anonymous pre and post questionnaires capture demographic background, perceived disadvantage, knowledge of surgical training and interest in pursuing surgery, alongside free text reflections. Fifty eight pupils completed paired questionnaires. Knowledge scores increased from 4.5 to 7.6 out of 10, with 98 percent improving. Likelihood of pursuing surgery rose from 5.1 to 6.7, with 72 percent reporting increased interest. Thematic analysis identified academic pressure, financial constraints, mentorship access, pathway clarity and confidence as major influences on aspiration. OpSurg demonstrates that a brief standardized intervention, delivered at scale, can produce measurable gains in knowledge and interest while generating rich demographic and qualitative data. The model provides a reproducible template for evidence based widening participation and highlights the value of integrating real time evaluation into early surgical outreach.
