Main Responsibilities / Duties
The MSL – Hospitals (Infectious Diseases) is a field-based, non-promotional Medical Affairs role for the anti-infectives portfolio. The MSL leads peer-to-peer scientific exchange with hospital-based specialists and generates medical insights, with a central focus on appropriate antimicrobial use, antimicrobial stewardship, healthcare-associated infections (HAIs), and antimicrobial resistance (AMR), while preserving a clear separation between medical and commercial activities.

Scientific Exchange & Insights
- Deliver updated, balanced, non-promotional scientific information (clinical, microbiological, pharmacological/PK-PD, epidemiological, pharmacoeconomic) to hospital-based HCPs and key stakeholders.
- Generate, document, and communicate high-quality medical insights from the field to inform the medical strategy of the assigned portfolio.
- Engage on antimicrobial stewardship, appropriate use, HAIs, and AMR, contextualized to local resistance epidemiology and institutional needs.





KOL & Stakeholder Engagement / Medical Education
- Develop and maintain relationships with KOLs, academic centers, and medical societies; identify and develop rising scientific talent (potential investigators and speakers).
- Map and engage the hospital multidisciplinary ecosystem: ID services, ICU/critical care, emergency departments, clinical microbiology laboratories, hospital pharmacy, and infection-control committees.
- Prepare scientific materials (with Medical Manager approval) and support congresses, medical events, and educational programs; keep local experts' content accurate.

Clinical Research (Support / Facilitation)
- Support investigator and site identification, ISR proposals, and local publication input; collaborate on pharmacovigilance activities including RMP and PASS, and on inspection readiness. Study ownership, timelines, and budget remain with the responsible research function.
