To ensure meaningful progress across partner clinics, there is a pressing need for robust outcome-oriented methodological research. SORC actively engages in projects that are multi-disciplinary in nature, involving collaboration between at least two surgical clinics. These initiatives are designed to foster national and international cooperation, enhancing the quality and consistency of clinical outcomes. By aligning research efforts across diverse institutions, SORC helps generate evidence-based insights that benefit all participating clinics. This shared approach strengthens the global surgical research community.

Hospital data exists in separate systems: visits, imaging, etc... Interoperability focuses on connecting these systems, while standardization relates to using a universal language, which is vital for multicenter and international projects. Accessing standardized data allows research teams from various institutions to generate reliable and valid evidence for surgical outcomes.

Prediction models are being increasingly used to support surgical decision-making. Relying on individual patient profiles and healthcare characteristics, these models have the ability to support patients and clinicians in estimating risks/benefits of specific treatments and therefore in managing treatment expectations. These techniques often imply the use of statistical approaches (such as regression), or machine learning algorithms.

Interpretation of surgical outcomes depends on clinically meaningful thresholds such as Minimal Important Change (MIC), Substantial Clinical Benefit (SCB), and Patient Acceptable Symptom State (PASS). These guide decision-making and assessment of treatment success but are methodologically challenging, varying by patient population, outcome domain, and follow-up timing. Refining anchor-based and predictive modeling approaches can improve the validity and applicability of these thresholds, ultimately supporting more accurate evaluation and patient-centered surgical care.

Adverse event (AE) documentation in surgery is key to assessing safety and informing clinical decisions. Standardized frameworks, including Core Event Sets (CES) and severity classifications (Clavien-Dindo / CLASSIC), enable consistent reporting across settings. Building on prior CES and grading work, this structured approach improves transparency, benchmarking, and comparability in surgical outcome research.

Cost-effectiveness analyses assess whether surgical interventions provide sufficient health benefit relative to costs. By combining clinical and economic data, they inform evidence-based decisions on resource use and treatment strategies, helping ensure efficient and sustainable care.

Comparative benchmark analyses use standardized patient-reported outcome measures (PROMs) to evaluate provider performance from the patient perspective. Fair comparisons require appropriate PROM selection, follow-up timing, and case-mix adjustment. This approach identifies differences across providers and supports quality improvement in surgical care.
