Clinical AI Interface Layer Could Support Safer Adoption

Clinical artificial intelligence is expanding across specialties, creating a growing challenge for clinicians and health systems that must identify, assess and safely use an increasing number of tools. A perspective published in BMJ Health & Care Informatics proposes a clinical AI interface layer to help connect available models with clinical practice. The approach could give clinicians clearer information about available tools, their evidence, limitations and appropriate uses. It also addresses the organisational challenge of monitoring performance, governance and accountability as diagnostic aids, predictive models and decision support systems become more numerous and complex.

Growing AI Use Creates an Implementation Gap 

Many clinical AI tools are developed and tested in research settings, while the number and complexity of available models continue to grow. Individual tools may require different inputs, methods of interpretation and awareness of specific failure modes. As the range expands, clinicians may find it increasingly difficult to know which tools are available, when they should be used and how their strengths and limitations compare. The challenge may therefore shift from a lack of reliable tools to the difficulty of keeping track of them and using them appropriately. 

Health systems face a similar problem. Effective adoption requires structures that can catalogue tools, monitor their performance and help clinicians understand the evidence supporting them. Without a mechanism linking clinicians to appropriate tools, even well-validated systems may remain underused. Models may also remain limited to narrow development environments, reducing opportunities to improve them in response to clinical needs and different patient populations. 

Fragmented development and distribution can make deployment more difficult. Health systems may lack clear information about how model inputs, outputs and workflow requirements fit into existing processes. These gaps can increase the distance between AI development and practical clinical use. 

A Clinical AI Interface Layer Could Organise Tools 

A clinical AI interface layer could provide a structure between the growing range of tools and the clinicians expected to use them. One option is a centralised discovery platform giving clinicians a consolidated view of models relevant to a specific clinical task and the evidence supporting them. Tools could be organised by the inputs they require, the problems they address and the patient populations for which they were developed. 

For each algorithm, the platform could provide structured information on external validation, known limitations, potential biases, safety issues and changes in performance over time. It could also explain what data are needed, what the model produces and how its outputs should be interpreted. Information on applicable patient populations and evidence of clinical utility could be included in the same system. A clinician considering sepsis prediction tools, for example, could compare validated models relevant to the patient population being treated. 

Another option is a system similar to a hospital formulary, with a selected group of algorithms reviewed, approved and monitored within a health system. Such platforms would need careful implementation so that they do not add further complexity. Clear governance, institutional ownership, accountability when tools fail or cause harm and standardised evaluation would remain important. 

Dedicated Clinical Roles Could Support Integration 

Dedicated clinical roles could complement discovery platforms by helping connect AI development with clinical practice. These clinicians would focus on translating and deploying models rather than developing them or managing wider health information technology infrastructure. Their responsibilities could include interpreting model outputs for individual patient cases, explaining limitations and appropriate uses and supporting safe integration as tools change. 

A more transparent discovery system could also make information about AI tools and their limitations easier to access across institutions with different levels of technical capacity. More consistent information may reduce variation in how tools are used and allow more reliable comparisons of model quality and external performance. Standardisation could therefore cover not only how tools are listed but also how their evidence, risks and practical requirements are communicated. 

The interface layer would not necessarily be a single technology. It could combine discovery platforms, organisational structures and specialised clinical expertise. Its purpose would be to help clinicians identify, understand and use available tools while giving health systems a clearer structure for deployment, oversight and monitoring. This could help bring clinical adoption closer to the pace at which new AI tools are being developed. 

Clinical AI adoption depends not only on developing new models but also on creating practical systems that make them easier to find, understand and manage. A clinical AI interface layer could organise information on clinical tasks, inputs, outputs, validation, limitations, safety and performance. Specialist clinical roles could support this structure by helping translate models into practice. Together, these approaches aim to make the growing number of AI tools easier for clinicians and health systems to assess, oversee and use safely.
