Introduction: Postoperative infections represent a significant burden of disease, demanding antibiotic prescriptions, and are contributing to antimicrobial resistance. The burden of infection as a surgical complication is greater in low- and middle-income countries (LMICs). We report the protocol of a pilot study for the co-design, implementation and evaluation of two infection prevention and control (IPC) and antimicrobial stewardship (AMS) interventions across the surgical pathway in a teaching hospital in India. Methods and analysis: The two interventions developed following in-depth qualitative enquiry are (i) surveillance and feedback of postoperative infections to optimise the use of antibiotics in two surgical departments (gastrointestinal and cardiovascular and thoracic surgery) and (ii) raising awareness amongst patients, carers and members of public about IPC and AMS. We will conduct a prospective study, formatively evaluating the implementation process of delivering the two co-designed interventions using implementation science frameworks. The study will systematically assess the context of intervention delivery, so that implementation support for the interventions may be adapted to the needs of stakeholders throughout the study. Analysis of implementation logs and interviews with stakeholders upon completion of the implementation period, will offer insights into the perceived acceptability, appropriateness, feasibility and sustainability of the interventions and their implementation support. Implementation costs will be captured descriptively. Feasibility of clinical data collection to investigate effectiveness of interventions will also be assessed for a future larger study. Thematic framework analysis and descriptive statistics will be used to report the qualitative and quantitative data, respectively. Strengths and limitations of this study: • The paired interventions have been co-designed from their inception with involvement of stakeholders at different stages in the surgical pathway. • Simultaneous evaluation of implementation and clinical outcomes will inform the development of a future larger study to enable/assess the scalability of interventions • The study offers a novel combination of implementation theory-informed, stakeholder-driven and clinically relevant evaluation, carried out in the context of a middle-income country hospital. • The project may not be applicable to every low-resource setting and surgical context due to differences in healthcare systems and cultures. However, the application of implementation science concepts may facilitate transferability and adaptation to other settings.
