## TL;DR

Instead of asking twenty hospitals for permission, a researcher would apply once to a single national body that can grant access to all cancer records under one set of rules.

## Summary

The European Health Data Space regulation (2025) creates health data access bodies that grant permits for secondary use across all holders in a member state. The proposal is a cancer-specific instance: one permit authority, one data catalogue, one set of standard extraction pipelines (OMOP and mCODE), and statutory deadlines for holders to comply. England's NHS Research Secure Data Environment network and Finland's Findata are working precedents; the US has no equivalent.

## Fields

- Kind: Idea
- Last checked: 2026-09-08
- Hypothesis: A single-permit cancer data space cuts the median time from research question to approved dataset from more than a year to under 90 days and increases the number of multi-centre real-world studies per year at least threefold.
- Rationale: Findata reduced permit times to weeks; the bottleneck in most countries is not technology but the need to negotiate with each data controller separately. Statutory duty to provide data, with a single authority, removes the negotiation.
- Proposed test: Track permit time, dataset delivery time and study output for one cancer-focused access body over three years versus the previous multi-controller process in the same country; publish the comparison.
- Maturity: early-clinical
- Actor: policy
