Objective: This study aimed to explore the impact of a human factors intervention bundle on the quality of ward-based surgical care in a UK hospital.

Summary of Background Data: Improving the culture of a surgical team is a difficult task. Engagement with stakeholders before intervention is key. Studies have shown that appropriate supervision can enhance surgical ward safety.

Methods: A pre-post intervention study was conducted. The intervention bundle consisted of twice-daily attending ward rounds, a "chief resident of the week" available at all times on the ward, an escalation of care protocol and team contact cards. Twenty-seven junior and senior surgeons completed validated questionnaires assessing supervision, escalation of care, and safety culture pre and post-intervention along with interviews to further explore the impact of the intervention. Patient outcomes pre and postintervention were also analyzed.

Results: Questionnaires revealed significant improvements in supervision postintervention (senior median pre 5 vs post 7, P = 0.002 and junior 4 vs 6, P = 0.039) and senior surgeon approachability (junior 5 vs 6, P = 0.047). Both groups agreed that they would feel safer as a patient in their hospital postintervention (senior 3 vs 4.5, P = 0.021 and junior 3 vs 4, P = 0.034). The interviews confirmed that the safety culture of the department had improved. There were no differences in inpatient mortality, cardiac arrest, reoperation, or readmission rates pre and postintervention.

Conclusion: Improving supervision and introducing clear protocols can improve safety culture on the surgical ward. Future work should evaluate the effect these measures have on patient outcomes in multiple institutions.
