Benchmarking pancreaticoduodenectomy (PD) outcomes provides standardized references. Established benchmarks reveal high morbidity but allow for meaningful comparisons across surgical approaches and centers.
Area of Science:
- Surgical outcomes research
- Pancreatic surgery standardization
- Healthcare quality improvement
Background:
- Current outcomes after pancreaticoduodenectomy (PD) lack standardized benchmarks, hindering comparative analysis.
- The best achievable results following PD are not well-defined, making comparisons speculative.
- Variability in PD outcomes necessitates the establishment of reliable reference points.
Purpose of the Study:
- To establish robust and standardized outcome benchmarks for pancreaticoduodenectomy (PD).
- To enable meaningful comparisons of PD outcomes across different patient cohorts, centers, and surgical techniques.
- To define best achievable results after PD using a benchmarking approach.
Main Methods:
- Analysis of consecutive PD cases (2012-2015) from 23 international expert centers.
- Identification of 20 outcome benchmarks using low-risk PD cases (no comorbidities, no major vascular resection).
- Validation of benchmarks in cohorts with higher comorbidity (ASA class ≥3) and minimally invasive approaches.
Main Results:
- Low-risk PD cases (38%) showed low in-hospital mortality (≤1.6%) but high cumulative morbidity (73% within 6 months).
- Established benchmark cutoffs: pancreatic fistulas (19%), severe complications (30%), and failure-to-rescue (9%).
- Higher comorbidity cohort (ASA ≥3) had increased in-hospital mortality (3%) and failure-to-rescue (16%) compared to benchmarks.
Conclusions:
- Proposed PD outcome benchmarks, derived from a large international cohort, facilitate standardized comparisons.
- These benchmarks can be applied to assess outcomes across diverse patient groups, institutions, and surgical modalities.
- Benchmarking aids in evaluating the quality of care and identifying areas for improvement in pancreatic surgery.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
