The Weight
of the Work
The 2023 SCAI Survey lays bare a profession-wide health crisis: two-thirds of cath lab staff report pain from lead aprons, 60% have sustained orthopedic injuries, and the toll on careers, cancer risk, and wellbeing is mounting.
A Profession Under Physical Siege
Interventional cardiologists and cardiac catheterisation laboratory staff occupy a unique position in medicine: they perform technically demanding, often physically strenuous procedures whilst standing in a field of scatter radiation, encased in protective garments that can weigh upwards of 4.5 kg. Hour after hour, procedure after procedure, career after career.
The 2023 SCAI (Society for Cardiovascular Angiography and Interventions) Survey, published in the Journal of the Society for Cardiovascular Angiography and Interventions in March 2025, provides the most comprehensive recent snapshot of this occupational reality. Conducted by SCAI's Professional Well-Being Committee, the survey compared data collected in 2023 with earlier surveys from 2014, mapping how the burden of occupational injury has — or has not — changed across a decade of technological progress.
296 respondents completed the survey between May and August 2023: 91% interventional cardiologists, 7% fellows-in-training, and 2% interventional echocardiographers or invasive non-interventional cardiologists. Despite an 8% response rate (typical for professional society surveys of this type), the findings are consistent with a large body of prior evidence and carry significant statistical weight.
Lead Aprons and the Spine: A Career-Long Injury Pattern
The most striking finding is the ubiquity of orthopaedic injury. Fully 82% of respondents reported musculoskeletal pain or orthopaedic injury from working in the CCL — with 66% specifically attributing pain to lead apron use. The pattern of injury follows the anatomy of load-bearing: lumbar spine injuries (34%), cervical spine injuries (25%), and wrist, elbow, and shoulder injuries (~20%) dominate.
Only 18% of respondents reported no injuries from CCL work. The remaining 82% represent a profession in which orthopaedic injury is not the exception — it is the expectation.
| Injury Type | Prevalence | Scale |
|---|---|---|
| Lumbar spine injury | 34% | |
| Musculoskeletal pain (lead-related) | 66% | |
| Any orthopaedic injury | 60% | |
| Cervical spine injury | 25% | |
| Hip/knee/ankle injury | ~20% | |
| No injuries reported | 18% |
Critically, the injury burden increases with age and experience — precisely the cohort that represents the profession's most skilled and productive members. The survey found that respondents who had sustained injuries were significantly more likely to have already engaged in physical therapy, strength training, or other mitigating activities — suggesting that the profession is individually managing a systemic problem.
Two-thirds of our colleagues experience work-related pain attributable to wearing lead aprons, 60% experience an orthopaedic injury, and nearly 1 in 5 limit their procedural workload owing to such an injury.
Dr Ryan Madder — Commentary on the 2023 SCAI Survey, JSCAI 2025Beyond Orthopaedics: The Radiation Health Burden
Orthopaedic injury may be the most visible occupational hazard of cath lab work, but radiation exposure carries its own long shadow. Approximately 6% of survey respondents reported a personal cancer diagnosis — a rate described by the study authors as "far exceeding normal rates." The authors also note that 5% reported cataracts or skin injury attributable to occupational radiation.
Perhaps most striking is the social evidence: 11% of respondents said they knew a colleague who had developed a brain tumour. This figure is not derived from epidemiological surveillance — it is a lived experience rate reported by the professionals themselves. The left-sided laterality of brain tumours in interventional cardiologists (where the radiation source sits during most fluoroscopy procedures) has been documented elsewhere in the literature and lends biological plausibility to this signal.
The survey authors acknowledge survivorship bias as a potential limitation — those who have suffered the most severe radiation injuries, including fatal cancers, are by definition not present to complete a survey. The true cancer burden may therefore be underrepresented in these figures.
- 6% of respondents reported a personal cancer diagnosis — characterised by authors as far exceeding population norms
- 5% reported cataracts or radiation-induced skin injury
- 11% knew a colleague with a brain tumour — consistent with prior published data on left-sided brain tumour prevalence in interventional cardiologists
- Cancer and cataract rates were described as approximately threefold higher than those observed in the general population
- Survivorship bias likely means these figures underestimate the true burden
Injuries Are Ending Careers and Shaping Who Enters the Field
The consequences of these injuries extend beyond individual clinicians to the sustainability of the speciality itself. Approximately 20% of survey respondents had limited their procedural workload due to injury or the desire to reduce radiation exposure. The career impact is acute for a speciality that depends on high-volume, high-skilled proceduralists.
The data on pregnancy highlights a further structural inequality. Among female respondents, 28% reported being discouraged from working in the cath lab during pregnancy, while 71% said they would want to step away during pregnancy. Flexible policies, adequate radiation monitoring during pregnancy, and supportive workplace practices are evidently not universal despite the profession's longstanding awareness of the issue.
There is also a pipeline dimension: when early-career clinicians observe colleagues with chronic back pain, orthopaedic surgeries, or early retirement, the deterrent effect on recruitment — particularly of women into interventional cardiology — is compounded by the physical burden itself.
The risks associated with working in the CCL remain unacceptably high. We must act now to implement stronger protections to ensure the long-term health and safety of interventional cardiologists and cath lab staff — and the sustainability of our profession.
James B. Hermiller MD, MSCAI — co-author, 2023 SCAI SurveyWhat the Survey Says About Protective Behaviour
More than three-quarters of respondents reported engaging in some form of preventive or injury-management activity — strength training (47%), stretching or yoga (42%), other exercise (48%), massage (21%), or ergonomic improvement (14%). The number of self-reported injuries correlated significantly with engagement in these activities, suggesting that injured clinicians are actively seeking mitigation strategies rather than simply accepting injury as inevitable.
Despite availability of newer radiation protection technologies — including suspended lead suits, zero-gravity radiation shields, and improved table-mounted shielding systems — adoption remains inconsistent. Survey respondents cited high costs and administrative barriers as the primary obstacles to accessing these solutions, even where clinical willingness exists.
- Cost of newer radiation protection systems cited as the primary barrier to adoption
- Administrative and procurement barriers prevent individual clinicians from accessing alternatives independently
- Institutional inertia — lead aprons remain the default despite evidence of their injury burden
- Inconsistent access to dosimetry monitoring across institutions and geographies
- Lack of standardised guidelines specific to cath lab ergonomics and radiation protection
From Survey Data to Structural Action
The 2023 SCAI Survey is not, in isolation, novel in its findings — the same patterns of orthopaedic injury and radiation concern have been documented in prior SCAI surveys and in the broader literature. What makes this dataset significant is the consistency of the signal over time, and the explicit professional consensus it has generated: the SCAI is working toward a formal multi-society consensus statement on occupational hazards in the CCL, in collaboration with peripheral vascular and interventional radiology societies.
The path from data to change requires action at multiple levels. At the institutional level, procurement decisions need to account for the full occupational cost of conventional lead aprons — not just purchase price but the long-term burden of musculoskeletal injury, lost procedural time, and career attrition. At the regulatory level, standards for occupational radiation protection in interventional settings require updating to reflect both the evidence of harm and the availability of better alternatives. At the individual level, the profession needs to dismantle the cultural expectation that physical suffering is the price of a career in interventional cardiology.
The data provided by this survey constitute, in the words of one co-author, "an undeniable call to action." The question is whether that call will be answered with structural change, or whether the next decade's survey will report the same familiar statistics.
