-Germany recorded an overall 3.8 % in‑hospital neurosurgical mortality in 2023 (8,338/222,158 cases), with significant gender disparity (men > women) and diagnosis‑specific variance. Traumatic and hemorrhagic conditions had highest fatality, surgical intervention mortality ranged 1–9 %. The study offers a national benchmark but is limited by administrative data lacking clinical depth or causality. 
 ---- ----
-- **Methodology fragility**: Reliance on billing datasets (§ 21 InEK) introduces severe bias—diagnoses and procedures are defined by coding practices, not clinical validation. No cross‑checking with patient records, no severity stratification, no time‑to‑event data—makes all mortality rates superficial at best. 
-- **Misinterpretation danger**: Presenting crude mortality rates without risk adjustment (e.g. age, comorbidity, functional status) is misleading. The significant sex difference (3.3 % vs 4.2 %) could reflect confounding, not true gender effect. 
-- **Incremental novelty**: Similar national audits exist (e.g. UK, US); this offers no new methodological or analytical insight. It merely transposes known benchmarks to Germany without advancing granularity. 
-- **Inadequate discussion of limitations**: Authors acknowledge lack of causal inference but still present data as benchmarks. They fail to address potential misclassification or repeated admissions bias—they assume one fatal case equals one patient death. 
-- **Logical leaps**: Highlighting procedure‑based mortality (e.g., vascular reconstructions 9 %) without denominator contextualization (case complexity, emergent status) is irresponsible—it risks penalizing high‑risk centers. 
-- **Conclusions overstate utility**: The claim that this “may inform clinicians, policymakers, and patients” is hollow—administrative aggregate mortality without granularity lacks actionable inference for any stakeholder.

-Flawed epidemiological exercise. Data too crude to serve as quality benchmark; superficial sex analysis; absent risk adjustment severely limits interpretability.+**Flawed epidemiological exercise.**
