Procedure logbooks for Interventional Radiology Portfolio Pathway: what assessors need to see

Why procedure evidence carries most weight in IR

Interventional Radiology is one of the most procedurally intensive specialties in the NHS. Where a general physician specialty Portfolio Pathway application is built from a mix of clinical assessments, reflective practice, audit, structured reports and management evidence distributed across the four GMC domains, an IR application places the procedure logbook at the centre. The other evidence domains remain necessary - multi-source feedback, audit, teaching records, and structured referee reports all need to be present and credible - but they play a supporting role. Assessors arrive at the logbook first and weight it most heavily.

That weighting is not arbitrary. The RCR Clinical Radiology curriculum describes IR in terms of technical competencies that can only be demonstrated through a record of performed procedures. Patient selection, consent and complication management are clinical judgement skills, but they are exercised in the procedural context. A portfolio that contains strong reflective practice and audit evidence but a thin, unstructured logbook will not satisfy the RCR assessment panel, regardless of how well everything else reads.

We have seen applications from experienced senior IRs stall at the Royal College assessment stage specifically because the procedural evidence was difficult for assessors to evaluate - not because the practice was inadequate, but because the logbook was formatted in a way that obscured the breadth and independence of the work. The clinical competence was present. The evidence packaging was not. This is a correctable problem, and the purpose of this article is to show you how to correct it before you open your GMC Online application window.

This article is a companion to the Interventional Radiology Portfolio Pathway complete guide, which covers the full application process including the IR CiP set, the non-CCT route, and a realistic evidence-building timeline. The focus here is specifically the procedure logbook.

IR's position within the Portfolio Pathway framework

Interventional Radiology occupies an unusual position in the GMC registration framework. Clinical Radiology is a full specialty with a 2022 curriculum and a recognised CCT training pathway. IR is a subspecialty that builds on that Clinical Radiology foundation, with its own dedicated curriculum published by the RCR. For Portfolio Pathway purposes, the RCR acknowledges two possible routes for IR applicants.

The first is a full Clinical Radiology Portfolio Pathway application that incorporates IR as the dominant strand of procedural evidence. This is the more common route for applicants who have a background combining diagnostic radiology and IR. It requires coverage of the full Clinical Radiology CiP set, with IR CiPs 13 and 14 providing the procedural core.

The second is a non-CCT Portfolio Pathway application specifically in Interventional Radiology, which the GMC permits where an applicant's practice is exclusively or predominantly IR. The RCR provides guidance on this through its Specialty Advisory Committee for Clinical Radiology. Applicants considering this route should seek written confirmation from the RCR before building their evidence portfolio, since the scope of the CiPs that need to be addressed, and what appears on the Specialist Register entry, differs from a broad Clinical Radiology application. The specialty specific guidance article explains how to read and map against an SSG in detail.

Both routes are governed by the GMC's four domains of Good Medical Practice and the SSG for Clinical Radiology. The two CiPs that matter most for your logbook are described in the cards below. These are the primary framework through which assessors evaluate procedural evidence.

What the GMC SSG and RCR curriculum expect

The GMC Specialty Specific Guidance for Clinical Radiology references the RCR curriculum and specifies that evidence of IR competence should include a comprehensive procedure logbook demonstrating breadth across the core IR procedure categories, documented evidence of independent practice at Consultant-equivalent level, direct observation assessments (Rad-DOPS or equivalent) from named senior colleagues, complication rate tracking against published benchmarks, evidence of pre-procedure clinical decision-making including patient selection and consent, post-procedure care and complication management records, and participation in IR multidisciplinary team meetings and relevant governance structures.

The SSG does not publish a minimum procedure count. This is a deliberate choice. Assessors reviewing IR applications are Clinical Radiologists and IRs themselves. They know what a genuine Consultant IR practice looks like in terms of volume, breadth and case complexity. An application that reflects a real, substantive IR practice is distinguishable from one built on a narrow or restricted procedural base, regardless of whether a specific threshold is applied.

The capabilities in practice article covers the CiP framework across all specialties. For IR specifically, CiPs 13 and 14 cannot be read in isolation from the broader Clinical Radiology CiP set. Even on the full CR route, your logbook remains the primary procedural evidence, and the other CiPs are addressed through the non-procedural elements of your portfolio: audit, MSF, teaching, clinical governance and reflective practice.

The British Society of Interventional Radiology (BSIR) is the professional body for IR in the UK. Its logbook guidance and quality standards for IR practice are the operational framework assessors use alongside the RCR curriculum when evaluating procedural evidence. These documents are available on the BSIR website. Reading both the GMC SSG and the BSIR guidance before designing your evidence build is not optional preparation. It is the foundation on which an evidence strategy can be constructed.

Procedure categories: what to log and how

IR encompasses a wide range of procedure types. A credible Consultant-level application needs to demonstrate competence across the major categories, not depth in one or two with nothing elsewhere. An applicant who has performed high volumes of peripheral angioplasty but has no biliary, non-vascular drainage, or emergency haemorrhage control evidence is not demonstrating the breadth the RCR curriculum describes for a substantive Consultant IR post.

The table above describes a framework, not a minimum checklist where every row must be ticked. Not every IR post covers all procedure types. An IR Consultant at a large tertiary centre with an established oncology IR programme will have TACE, ablation and TARE evidence that a district general hospital IR Consultant may not. What matters is that the logbook reflects the genuine scope of your post honestly, and that gaps in any category are explained rather than left for assessors to interpret.

For each procedure entry in your logbook, the minimum data set assessors need is: procedure type and specific technique, clinical indication, imaging guidance modality used, your grade and supervision level for that case, technical outcome (success, partial success, or failure with reason), immediate complications, and date. Many applicants log only procedure type and date. That format answers the question "did this happen?" but not "was it done well and at what level of independence?" The latter is what assessors are trying to establish.

Presenting procedure numbers without a fixed threshold

The absence of a fixed procedure count creates a genuine challenge at the presentation stage. In gastroenterology, the JAG certification threshold anchors the endoscopy evidence to a known standard. In IR, you are presenting evidence of competence without that published anchor. The approach that works is comparative and narrative: you describe your practice in the context of what an independent IR Consultant actually does, and you present numbers that make sense within that context.

The questions an assessor needs your logbook to answer are specific. What procedures does this applicant perform, across which categories, and at what grade? How frequently, and over what portfolio period? At what level of independence - supervised, assisted, or independent? What does the case mix look like across elective and emergency work? Is the practice consistent and current, or does it show large gaps or a sudden volume increase immediately before application?

A logbook that answers these questions explicitly, with a clear structure and a written reflective summary, performs significantly better than a raw list of procedure dates and types. The summary table (totals by category, independence level, date range) should be the first document an assessor encounters, followed by the narrative reflection, followed by the full chronological log. This structure takes an assessor from high-level pattern recognition to detailed verification, rather than asking them to build the pattern themselves from an unstructured list.

The reflective practice article covers the written reflection framework in detail. For procedural evidence specifically, the reflection must link the procedures described to the relevant CiPs and explain how independent practice was established. Where there are gaps in the logbook - a period of lower volume, a category that is underrepresented - the reflection is where you contextualise and address them. An unexplained gap reads as an unaddressed weakness. An explained gap, with a note on why it exists and what you have done to close it, reads as self-awareness.

The portfolio pathway timeline article covers realistic timescales for building an evidence base strong enough to support an application. For IR applicants, this is typically a minimum of two to three years of substantive independent IR practice, though earlier applications are possible where the evidence base is strong.

Case mix: elective, emergency and complex cases

Case mix is one of the clearest indicators of whether an IR post genuinely supports a Portfolio Pathway application. A Consultant IR post at an NHS Trust of any size involves both planned elective work in procedure-specific sessions, and unplanned emergency work through on-call commitments and acute referrals during working hours. The elective work builds volume and subspecialty depth. The emergency work demonstrates independent decision-making under time pressure and provides the primary evidence for CiP 14.

Emergency IR evidence is particularly important to assemble deliberately, because it is the category most frequently thin in Portfolio Pathway applications. On-call cases happen unpredictably, procedural documentation is often completed quickly and without the same detail as elective cases, and the sense of "I was there and did it" does not translate into the logbook automatically. The habit of logging emergency cases with the same minimum data set as elective ones, on the day or the following morning, is a practical discipline that pays off significantly at the evidence stage.

Emergency IR evidence typically includes cases from the on-call list: traumatic haemorrhage control (pelvic ring fracture embolisation, splenic or hepatic injury management, polytrauma haemorrhage), upper GI bleed embolisation following failed endoscopic management or as primary treatment in haemodynamically unstable patients, post-partum haemorrhage uterine artery embolisation, acute limb ischaemia catheter-directed thrombolysis or mechanical thrombectomy, acute biliary obstruction and sepsis requiring emergency PTBD, and similar acute escalations.

If your current post does not include on-call IR, this is a meaningful gap in your evidence base that needs to be addressed before you apply. Assessing whether your current Trust can support the evidence build you need is covered in the what a PP-supportive Trust looks like article. The educational supervisor relationship article covers how to use your educational supervisor to plan for gaps like this in advance of application.

Rad-DOPS: getting observed assessments for procedural work

Direct Observation of Procedural Skills in the Clinical Radiology context - referred to as Rad-DOPS - forms part of the RCR's workplace-based assessment framework. The general DOPS framework applicable across all specialties is covered in the workplace-based assessments article. For IR-specific Rad-DOPS, the key points are as follows.

Rad-DOPS must be completed by a named Consultant colleague who was present and directly observed the procedure. The assessment covers the full procedural episode: pre-procedure planning and patient preparation, technical performance including imaging interpretation during the procedure, communication and consent where relevant to the observed session, complication recognition and management, and post-procedure care and documentation. A Rad-DOPS that covers only the technical execution of the procedure and nothing else is a partial assessment.

For IR Portfolio Pathway purposes, aim for at least two Rad-DOPS per major procedure category per 12-month portfolio period. The most common error in IR Rad-DOPS collections is selecting only straightforward, low-risk cases for direct observation, because they are easier to arrange and less likely to produce an adverse event during the assessment. Assessors with IR experience recognise a Rad-DOPS collection built around simple cases. Prioritise cases that show your range: a technically complex angioplasty in challenging anatomy, an emergency embolisation under time pressure, a difficult biliary access in an altered anatomy patient, an ablation with a proximity challenge. These are the cases that demonstrate Consultant-level competence, and they are the cases that produce the most informative assessments.

Complication rates, outcomes and governance

Tracking and presenting your personal complication rates is expected of any IR Portfolio Pathway applicant. This is not about presenting a perfect record. Every experienced IR Consultant in NHS practice has complications - some procedural, some related to patient selection or the underlying clinical complexity, some unavoidable. What assessors look for is a practitioner who knows their own complication rates, tracks them against published standards, understands why complications occur, and has participated in the governance processes that review and learn from them.

The dashboard above is an illustrative format. The specific benchmarks for individual IR procedure types are published by the BSIR and vary depending on the procedure, patient population, and clinical indication. Before assembling your complication data for Portfolio Pathway purposes, download the current BSIR quality standards and map your personal rates against the relevant procedure-specific thresholds. Where your rate exceeds benchmark, address this in your reflection: was there a case mix factor (higher-risk referrals, complex anatomy, emergency cases included in the denominator that should be separated)? Was there a learning curve associated with a new technique or new imaging system? Has the rate since improved?

Governance participation means more than attending a meeting. It means presenting cases for peer review, actively contributing to M&M (morbidity and mortality) discussions, participating in departmental audit linked to procedure quality, and engaging with any national reporting frameworks (such as those associated with specific BSIR registries). The significant event analysis article covers how to document a serious complication or adverse event for Portfolio Pathway purposes in a way that demonstrates reflective practice rather than minimisation. An SEA submitted as Portfolio Pathway evidence following an IR complication, handled honestly and with a clear learning narrative, is stronger evidence of professional practice than a record with no complications at all.

MDT participation is a specific requirement of the RCR curriculum. For IR applicants, the relevant MDTs are the IR team meeting or morbidity and mortality conference, the oncology tumour board (if your post includes oncological IR work), the vascular MDT (for vascular surgery collaboration cases), and any organ-specific MDTs where IR contributes as a core modality. Keep a log of meetings attended with date, meeting type, and your role (presenter, discussant, attendee). The leadership and management evidence article covers MDT participation evidence in the broader management domain context.

Building your IR procedure evidence package

The IR procedure evidence package should be a self-contained, clearly indexed section of your portfolio that takes an assessor from "what procedures does this applicant perform?" to "are they competent, do they have breadth, and do they reflect meaningfully on their practice?" without needing to search for information across multiple unconnected sections. The format below is based on what makes a procedural logbook easy to evaluate: high-level summary first, supporting detail available but not buried in the summary.

The most important principle is that the evidence package should be self-explanatory. An assessor who picks up your IR procedural section in isolation, without reading your personal statement or the rest of your portfolio, should be able to understand what you do, at what level of independence, across what range of procedures, and over what period of time. If they cannot, the evidence needs restructuring, not expanding.

The five-year evidence currency rule applies to IR logbooks exactly as it applies to all Portfolio Pathway evidence. The recent evidence and the five-year rule article explains the GMC's position on evidence currency in detail. Practically, this means that procedures performed more than five years before your application date carry reduced weight unless supplemented with recent evidence. If the bulk of your logbook is more than five years old, building current evidence is the priority, not polishing the historical record.

The structured reports from referees article covers how to use your referee reports to reinforce procedural evidence. For IR applicants, a structured report from a senior IR colleague who has directly observed your practice and can speak to your procedural independence, case mix, and complication management is one of the most valuable items in the portfolio. The logbook provides the data; the referee provides the contextualisation from someone who has watched you work.

Overseas IR evidence: the translation challenge

Doctors whose IR experience was gained outside the UK - in Europe, North America, the Middle East, South Asia, or elsewhere - face the same evidential challenge as in every other procedural specialty: assessors need confidence that the overseas practice is genuinely equivalent to Consultant-level UK IR practice. Without a framework to anchor that comparison, a logbook alone does not establish equivalence.

The principle for overseas evidence is the same as in every procedural specialty: the burden of proof sits with the applicant to demonstrate equivalence, not with assessors to assume it. A logbook of 300 embolisation procedures from a high-volume overseas centre, presented without complication data, without a mapping document, and without any UK-based direct observation assessment, does not demonstrate Consultant-equivalent UK IR practice. It demonstrates that 300 embolisations were performed in that centre. These are very different things.

If you have spent any period practising IR in an NHS Trust, obtain UK Rad-DOPS now, regardless of how recently you arrived in the UK. Even a small number of UK-observed procedures provide an evidence anchor that overseas logbooks cannot replicate: they demonstrate that a UK-trained Consultant colleague has directly observed and assessed your technique in a UK clinical setting, and they link your overseas evidence to a verifiable UK standard. This is the single most impactful action available to an overseas-trained IR applicant who is currently working in an NHS post.

The direct-from-overseas route without UK employment is narrow and evidentially demanding. Assessors understand that it exists, but the burden of demonstrating equivalence through overseas documentation alone is high. For most applicants in this position, taking a UK post in a Specialty Doctor, Specialist Grade or Locum Consultant IR role before applying is the most practical route to building the evidence base the SSG requires. This is discussed more fully in the internationally-trained doctors article. If a UK post is a realistic option, the after-submission article explains what the assessment process looks like from the other side, which can help you understand what assessors are looking for before you begin building evidence.
