Consider a familiar position. An imaging director is responsible for MRI services across four sites — two district hospitals and two community diagnostic centres operating under the same trust. On a Wednesday afternoon she receives a request: one of the MRI radiographers at the largest site is unexpectedly off for a fortnight; can the lists be maintained by drawing on a radiographer who normally works at the second district hospital? The radiographer is known. Her competency is not in question. The question is governance: whether her current verification status, her MR safety currency, her modality-specific standing are confirmed for the activity being requested, at the site where it will happen, on the day it needs to happen.
The answer, assembled from the verification system that covers the whole trust, arrives in a form that is technically complete and operationally insufficient. It confirms that the radiographer was credentialled at last review. It does not confirm whether that review was recent enough to be relied upon for cross-site deployment without further sign-off. It does not say whether the MR safety record was assessed against the specific environment at the receiving site. The governance system has answered a different question from the one being asked — not out of inadequacy in design, but because it was designed around the institution, not around the movement of clinical work through it.
This is the proximity problem. It is not a technology problem. It is a structural one.
Governance at institutional distance
The three features that distinguish a continuous governance posture from an audit-oriented one are currency, proximity, and accountability granularity. The previous article in this series addressed currency — the property that makes workforce data queryable rather than merely reportable. Proximity is the second, and in distributed imaging environments it is arguably the one most often overlooked, because it does not announce itself as a gap. It presents as delay, as additional sign-off, as the informal phone call that precedes any cross-site decision.
The structural mechanism is straightforward. A governance system built around an institution — its staffing establishment, its periodic review cycle, its documentation architecture — accumulates information at the institutional level. It answers institutional questions well: how many of the department's radiographers are currently credentialled? What proportion hold active modality verification? These are legitimate questions. They are the questions a governance framework built at institutional distance is structurally positioned to answer.
They are not the questions being asked on a Wednesday afternoon when a list needs to be covered and a deployment decision needs to be made across a site boundary.
Governance signal that operates at institutional distance from the point of clinical activity loses operational value with every layer of mediation that separates the record from the decision. In a single-site department with a stable complement, that distance is small enough to be manageable. In a multi-site trust, a regional diagnostic network, a group of independent providers operating under shared clinical governance, or any arrangement where the same radiographer routinely works across more than one location, the distance becomes structural. Each additional layer — site coordinator to department lead, department lead to governance system, governance system to central record — adds the possibility of drift between what the record says and what the situation requires.
The radiographer who was verified for cross-site MRI work six months ago may have undergone additional assessment since. Or may not have. The governance system at institutional distance does not know which, and the question of which matters depends entirely on where the clinical work is happening today, not on where the records are held.
What becomes possible when proximity is present
The imaging director's problem is not that she lacks information. It is that the information she has is not sensitive to the specific deployment she is considering. A governance signal that possesses proximity is structured differently: it is associated with the clinical activity at the level of the event, not solely at the level of the institutional record.
When proximity is present, the question "can this radiographer work this modality at this site tomorrow" is answerable from the governance record rather than requiring a separate verification process assembled on top of it. The cross-site deployment decision becomes a governance event in itself — one that either confirms standing or surfaces a specific gap — rather than a decision made in the space between governance events and retrospectively documented.
This matters particularly in environments where sessional working is prevalent, where radiographers and advanced practitioners move regularly between sites, and where remote-reading arrangements mean that the "site" at which clinical work occurs is sometimes a question of network rather than geography. In each of these settings, a governance signal anchored to the institution rather than to the practitioner-in-context will tend to provide false confidence: the record looks adequate at the institutional level while the specific deployment is under-governed at the point where it matters.
The value of proximity is not that it creates more governance activity. It is that it reduces the gap between the governance record and the clinical reality. A radiographer's verified standing travels with the radiographer — or, more precisely, is available at the point of the deployment decision rather than requiring assembly from a separate process.
What this argument does not claim
It is worth being careful about what proximity as a governance property means and does not mean. It does not mean that governance structures should be replicated at every site independently — that path leads to fragmentation and inconsistency, which are themselves governance failures. Nor does it mean that every cross-site deployment should trigger a full re-verification process. That would impose friction disproportionate to the risk and would, in practice, defeat the operational purpose of flexible workforce deployment.
What proximity means, in governance terms, is that the signal is sensitive to the context of the clinical activity — to where it is happening, under what arrangement, and whether the practitioner's current standing specifically covers that context. This is different from a universal re-check. It is, rather, a governance architecture that is aware of deployment context rather than one that is indifferent to it.
It also does not follow that proximity solves the full governance challenge in distributed environments. Currency — whether the underlying data is current at all — remains the prior condition. A proximate but stale signal is not more useful than a distant one; it is simply wrong in a different location. Proximity amplifies the value of current data. It does not substitute for it.
The mediated signal
There is a certain operational pragmatism that has grown up around the proximity problem without naming it. Governance teams in large trusts and regional networks have developed informal processes — the pre-deployment check, the site coordinator's confirmation, the lead radiographer's verbal clearance — that function as proximity mechanisms operating outside the formal governance architecture. These processes work, in the sense that deployments happen and are generally appropriate. They work because experienced people compensate, through professional judgement and institutional knowledge, for a governance signal that was not designed to reach the places it needs to reach.
The risk is not that these informal processes are unreliable. It is that they are invisible to the governance record. The professional judgement that cleared a cross-site deployment does not appear in the credential log. The site coordinator's confirmation is not a governance event. When the formal record is subsequently reviewed — in an audit, in a clinical incident review, in a regulatory inspection — the deployment will appear as either covered or not covered, and the nuanced professional process that made it appropriate will be absent. The artefact and the operating reality have drifted, through entirely reasonable operational behaviour, into the same divergence described in the first article in this series.
Remote-I is built around the proposition that the governance architecture can be made proximate without replicating it at every site — that the radiographer-modality verification record can be queried in deployment context rather than consulted after the fact. The platform operates across MRI, CT, PET-CT, and PET-MRI, and the accountability granularity that enables proximity to matter is the subject of the final article in this series.
A governance signal that does not follow the work is not a governance signal for the work that is being done. It is a record of governance for work that was done somewhere else, at some other time, under conditions that may no longer apply.
