Clinical centers
Sites participating in prospective multicenter platforms in emergency surgical disease.
Participate
Structured pathways for centers, analysts, and trainees.
CESOR works with collaborators through defined participation pathways tied to active platforms, methodological programs, and analytic needs. Participation is selective and based on program fit, operational readiness, and the ability to contribute reliable work.
Who participation is for
CESOR currently engages three collaborator groups.
Analysts
Methodologists, biostatisticians, and causal inference collaborators contributing to design, estimand specification, analysis planning, or execution.
Trainees
Residents, fellows, and research trainees contributing to defined platform, methods, or writing work under supervision.
Participation model
Participation is organized around active platforms and defined methodological work rather than open-ended affiliation.
Participation principles
Entry is structured, not open-ended.
CESOR does not operate as a general-interest network. Participation is organized around active studies, defined methodological programs, and specified operational roles. Prospective collaborators should fit the scientific question, the platform structure, or the analytic task.
Pathway 01
Clinical centers
Centers may participate in active prospective platforms when local case volume, data capture capacity, and protocol adherence are adequate for high-quality consecutive enrollment.
What CESOR looks for
- Local clinical leadership
- Capacity for prospective case identification
- Ability to complete standardized data collection
- Willingness to follow common definitions and timelines
- Interest in collaborative authorship within a governed multicenter structure
Typical roles
- Site investigator
- Site study coordinator
- Platform contributor
- Follow-up and data validation support
Pathway 02
Analysts and methodological collaborators
Analytic collaboration is centered on active platform questions, target trial emulation, causal inference, implementation work, and reproducible analytic infrastructure.
What CESOR looks for
- Demonstrated methodological fit
- Ability to work from explicit protocol logic
- Comfort with real-world observational data constraints
- Commitment to reproducible workflow and versioned outputs
- Willingness to contribute within a defined program structure
Typical roles
- Estimand and protocol development
- Bias diagnostics and design critique
- Statistical analysis planning
- Reproducible code and reporting workflows
- Methods manuscripts and platform-linked analyses
Pathway 03
Trainees
Trainee participation is best suited to individuals who want to work within an existing program of research rather than propose unscoped independent projects at entry.
What CESOR looks for
- Reliable execution
- Strong writing and analytic discipline
- Willingness to work within protocolized structures
- Clear availability and defined goals
- Alignment with emergency surgery outcomes research, causal inference, or implementation science
Typical roles
- Literature and protocol support
- Data quality and adjudication tasks
- Platform operations
- Drafting support for abstracts and manuscripts
- Supervised secondary analyses
Intake
Use IDES for initial submission.
New project ideas, collaboration proposals, and early-stage clinical questions should be submitted through IDES. IDES captures fit, feasibility, design requirements, and the appropriate next step.
Information that improves initial review
- The clinical or methodological question
- Why the question matters
- Whether the proposal aligns with an active CESOR platform or requires a new structure
- Available data, site infrastructure, or analytic capability
- The specific role or support requested
- Expected timeline, if known
Submission does not guarantee entry into the CESOR program. Proposals are reviewed for scientific fit, feasibility, overlap with existing work, and operational readiness.
