Ian Paterson operated across multiple private hospitals and an NHS trust for over a decade. The inquiry that followed his criminal conviction found that governance failures were not caused by a lack of regulation — CQC, the GMC, and NHS England all had oversight. They were caused by the fact that no single organisation could see the full picture. Each institution governed what happened within its walls. Nobody governed what happened between them.
This is the boundary problem. And it is structural, not exceptional. Every private healthcare operator — from single-site hospitals to PE-backed groups, from insurer networks to the consultant who splits a week between NHS and private — operates across organisational boundaries where clinical accountability, data governance, and regulatory responsibility fragment.
The series follows a deliberate architecture. It begins with the provider domain — how practising privileges create the first governance gap, and how the NHS-private interface exposes patients to two constitutional systems with no governed crossing. It then examines the insurer domain — the ungoverned constellation of provider networks, the clinical-commercial boundary at pre-authorisation where medical necessity meets policy wording, and the Seven Flows methodology that makes these risks measurable. It covers the technical domain — the digital front door where clinical consultations become commercial pathways, and why DCB 0129/0160 clinical safety standards stop at the boundary where risk is highest. It concludes with the regulatory convergence — six separate regulatory pressures (FCA Consumer Duty, CQC restructuring, MPAF, PHIN/CMA, HSSIB, and the DCB standards review) all arriving at the same structural gap within twelve months.
The golden thread is the Seven Flows — seven governance functions (Identity, Consent, Provenance, Clinical Intent, Responsibility, Service Routing, Outcome) that must be present at every organisational crossing for a boundary to be safe. Where a flow is absent, systemic risk accumulates. The Constitutional Crossings framework maps where these flows break down at each boundary type. Together, they provide a clinical governance framework for inter-organisational risk in private healthcare — the framework that does not yet exist anywhere else.
