AI Lifecycle in Healthcare: From Planning to Continuous Monitoring

AI application spans many areas including medical imaging, patient monitoring, clinical documentation, risk assessment, treatment, and administrative tasks. Developing an AI application for healthcare goes beyond training an algorithm and deploying it in the hospitals.

Healthcare decisions have implications on patient safety, privacy, and accessibility, as well as care-related outcomes. Thus, every AI application must be governed from conception to its decommissioning. The AI lifecycle in healthcare outlines the governance process for the responsible design, development, validation, deployment, oversight, maintenance, and discontinuation of AI systems in healthcare.

What Is the AI Lifecycle in Healthcare?

The AI lifecycle refers to the entire governance process of the design, development, and deployment of AI systems, as well as their ongoing maintenance and eventual discontinuation. The AI systems lifecycle differs from conventional software systems because AI systems learn from data. Therefore, the systems will function in unpredictable ways as the population of the patients served, the data, the medical practice, or the equipment used in the hospital changes.

A system that frequently delivers optimal results during its development phase may, in the course of time, perform sub-optimally in another hospital. Lifecycle management makes it possible for an organization to identify risks early, evaluate the system’s performance prior to deployment, and monitor the system in practice to assess and manage any changes.

Identifying the Healthcare Problem

The governance lifecycle commences with the precise identification of the clinical or operational problem to be solved. The development teams should answer the following questions: what healthcare problem are they intending to solve; what will the AI system users’ roles be; which patients stand to be impacted by the system; and what are the key performance indicators that will define the success of the system.

Use cases may be leveling the risk of health deterioration amongst patients, decreasing the prevalence of missed patient appointments, prioritization of time-sensitive x-ray scans, or making clinical documentation less tedious.

Health-related problems should be clear, focused, and meaningful in the clinical setting. As a rule, AI should be considered only if there are no other simpler, more efficient, and effective clinical solutions.

Establishing Governance

Governance involves assigning responsibilities and making decisions regarding control mechanisms for safety throughout the lifecycle. The organization must include the system’s purpose and acceptable use, the role of human oversight, privacy, and performance and reporting requirements, along with the procedures for reporting and approving updates.

Good governance removes ambiguity regarding responsibility and aligns the development of AI with clinical safety and quality, along with cybersecurity and data protection.

Collecting and Preparing Data

AI in healthcare relies on managed data that is relevant and accurate. When data is to be used, the team must consider consent, confidentiality, and ownership, as well as access control and data protection retention and transfer.

Preparation may include duplication removal, format and information centrality correction, standardization of terminology and unnecessary identifiers, and labeling of clinical events.

Data of poor quality produces poor results. In addition, the team must confirm that the data sets represent the intended population with regard to age, gender, ethnicity, condition, where data was collected, and the equipment and the care environment.

Developing the AI Model

The AI Model is developed by a specialized team. Suggested algorithms and methods are used to train the model to recognize patterns and predictions.

Data is taught to the model through training. Validation and test data evaluate adjustments and the final performance, respectively. Leakage of data must be avoided.

The model is a programmed construct of elements, such as data sources and descriptions of the criteria for inclusion, as well as the design and type of the model, along with the assumptions, limitations, and potential for failure.

Trade-offs between reliability and safety, speed, cost, and compatibility with legacy systems must also be made.

Validating Performance

The model must be able to generalize beyond the training data. Technical validation of a model may assess, among other things, the time taken to process a request, along with accuracy, sensitivity, specificity, precision, and the rates for false positives and false negatives.

Clinical validation determines if a system has realistic value. Testing must consider various patient demographics, the impact of the system on the clinical workflows, comprehension of the system among clinical staff, system reliability, and the potential harm caused by erroneous results.

External validation is important because it tests the model on data from a different hospital, population, location, or device.

Ethics and Regulation

AI in healthcare may fall under medical devices, privacy, cybersecurity, data protection, and healthcare regulations. Appointment scheduling software typically falls under fewer regulations than AI that prescribes treatments or identifies severe medical conditions.

From an ethical viewpoint, the most relevant would be the assessment of autonomy, justice, beneficence, and non-maleficience. Patients and care providers should know what the system does, how its outputs are to be interpreted, and the circumstances where human judgement will override the system.

Workflow Integration of AI

A precise AI system can still fail if it is not usable within a clinical workflow. Controlled pilots should be used to reveal issues within workflows and the system, along with new and unanticipated risks.

AI systems should be used within clearly defined boundaries. There should be unambiguous human responsibility for the implications of AI on clinical decisions and patient care.

Real-World Performance Evaluation

Evaluation of AI in healthcare should look at accuracy, missed cases, false alarms, response times, failures, overrides, user feedback and complaints, and impact on patients differentiated by groups.

AI performance should be continually monitored because of the impact of new data, changed clinical practices, new or updated equipment, altered patient populations, and changed data-entry methods on original performance.

System Updates

AI systems might need updates if the system is found to work incorrectly, if the system needs to become more accurate, to reduce security threats, or to support additional patient types.

If changes are made to the data, code, thresholds, interfaces, or model behavior, those changes must be documented, and those changes must be validated, tested, approved, and monitored.

Retiring the AI System

There are many reasons an AI system might be retired. Some of these reasons include that an AI system might be outdated, no longer be supported, be unsafe, be unnecessary, or be less effective than other solutions.

AI systems must be retired if the system’s overall performance is below an acceptable level, support for cybersecurity related to the system is no longer available, laws and regulations change, and the risks to using the system are greater than the benefits.

A system retirement plan must ensure that the data stored in the system is kept safe, that the records the system holds are kept safe, users of the system are notified, users no longer have access to the system, and that there is no interruption in the care of patients.

Final Thoughts

AI in healthcare begins with a real clinical or operational issue and goes on to include governance, preparation of data, development of the AI system, validation of the AI system, regulation of the AI system, implementation of the AI system, real-time monitoring of the AI system, routine updates of the AI system, and retirement of the AI system.

AI in healthcare must be seen as a system that is being managed on a continual basis. Meanwhile, safe and effective AI in healthcare requires the combination of system governance, data management, and monitoring.

FAQS

What are the main stages of the healthcare AI lifecycle?

Stages consist of identification of the issue, governance, data collection, development, validation, ethical and regulatory review, integration, deployment, monitoring, maintenance, and retirement.

Why must healthcare AI be monitored after deployment?

Healthcare AI must be monitored after deployment to support the identification of diminished accuracy, data drift, failures, security, and workflow issues, and inequitable results before causing injury.

Can AI replace healthcare professionals?

AI can support healthcare professionals by processing data and automating repetitive tasks, as well as identifying trends. Human judgement will always be needed to interpret results, and consider the patient, uncertainty, and take accountability.
