MLOps in Healthcare: Benefits, Challenges, and Best Practices
The application of machine learning in healthcare has gained traction for its benefits in diagnosing and managing risk, organizing clinical data, improving the efficiency of the hospital, and tailoring treatment options. However, building the right model is just the first step. Healthcare institutions are also responsible for the implementation, monitoring, maintenance, protection, and control of the model for the duration of its operational life.
Machine Learning Operations (MLOps) are the frameworks and methods used to manage the model lifecycle. It integrates and builds upon clinical knowledge, data science, and several disciplines of IT, to keep healthcare machine learning systems safe and reliable.
What Are MLOps in Healthcare?
The term MLOps describes the application of a set of software and engineering operations to the machine learning workflow. In the case of healthcare, MLOps also includes the fairness of the model, the validation of the clinical process, justification of the model, and the regulations of the healthcare industry. A model may be correct at the development stage, but may fail to be correct with a different set of patients, different equipment, different clinical procedures, and different data.
Therefore, healthcare MLOps is concerned with the complete lifecycle of the model, whereas other industries may consider the deployment of the model as the final step. This is especially important for machine learning systems embedded in medical devices, or clinical decision support systems, because of the inherent risks involved with the model and the need to control model performance and the risks of frequent updates.
Why Is MLOps Important in Healthcare?
Healthcare systems are especially dynamic. Changes in patients, diseases, and clinical systems are common. Likewise, the tools used in healthcare and the methods of data collection and recording may undergo frequent and radical changes.
MLOps prevents multiple issues by ensuring models can be monitored after deployment. Without MLOps, models can provide healthcare predictions without considering the performance of the model. This can lead to missed risks as the model fails to identify them and alerts that do not provide useful information.
Using MLOps provides healthcare teams the ability to:
- Ensure models are consistent
- Recognize changes in the data and predictions
- Control updates to the models
- Safeguard the privacy of patients
- Keep track of the development and the deployment of the models
- Enhance teamwork between the technical staff and the healthcare staff
- Improve response time when a system has malfunctioned
- Ease the burden of audits and compliance
MLOps and responsible AI have one critical concern in common: the continuous evaluation and monitoring of a system. The risks of using a system can be identified at any time.
The Healthcare MLOps Lifecycle
Data Collection and Preparation
Healthcare model data can be sourced in a multitude of ways, from electronic health records to administrative data. There are multiple ways data can be collected to be used to develop a model.
Data must be evaluated for a number of reasons before model construction can be initiated. At a minimum, the data must be evaluated for accuracy, completeness, consistency, and relevancy. Poor data can lead to unreliable results from the model.
Data must also be evaluated to ensure that it accurately reflects the population being targeted. If the data used to construct a healthcare model is limited due to the population, then the results from the model will likely be limited as well.
Model Development and Validation
During the development of a model, multiple things must be considered, such as the selection of the appropriate algorithm and the evaluation of the model. In healthcare, simply accuracy is not going to be enough.
Validation should encompass the following:
Tests should incorporate:
- Sensitivity and specificity
- Rate of false-positive and false-negative
- Performance across the broad patient population
- Functionality
- Consistency across varying conditions
- Interpretability
- Patient safety risk
Clinical specialists should determine whether the outputs generated by the model are meaningful and appropriate for the specified healthcare workflow. The performance of the integrated human AI System should also be considered.
Controlled Model Deployment
Once the model has been validated, it is incorporated into healthcare software and/or clinical workflows. This may also include integration with electronic patient record systems, clinical decision support systems, diagnostic and monitoring systems, and/or clinical dashboards.
A stepwise approach to deployment is preferable to an instantaneous full-scale deployment across the organization. It is common practice for the model to be used in an initial deployment to an ‘isolated’ environment where the outputs are generated and assessed, but are not used to impact clinical care directly.
Deployment should incorporate standard approval processes for deployment, the ability to retract the deployment, controlled access with accountability, documented procedures and instructions, and clearly defined roles and responsibilities.
Ongoing Performance Evaluation
Once a model has been deployed in a healthcare setting, the model should be routinely assessed. This may involve:
- Changes in the data being used
- Deterioration in prediction quality
- Unpredictable outputs
- Increased error outputs
- Differences in performance of the model based on the patient population
- Prediction delays
- System malfunction
- Attempts to breach the system
Technical performance of the model should be evaluated alongside clinical outcomes. It is possible a model continues to function from a technical standpoint, but outputs are no longer clinically valuable.
Model Update and Retraining
A model may need an update and retraining if data are added and/or its performance no longer matches the required standard. It should be noted, however, that retraining a model too readily and/or without appropriate controls may increase potential risks of the model.
Before any updated model version can completely replace the existing version, it must go through the validation, fairness testing, security checks, and clinical reviews. Older Version models must remain so that teams can analyze incidents and restore the model if needed.
Update policies must define what type of changes can be made, how those changes will be validated, and how the effects of those changes will be monitored.
Data Privacy and Security
Healthcare data is extremely sensitive. MLOps systems can work with data that contains Patient and Healthcare Professional Personally Identifiable Information and healthcare records including health images, diagnostic data, laboratory test results, and treatment history.
It is the responsibility of the organization to deploy all necessary administrative, physical, and technical safeguards to protect the privacy, security, and integrity of electronic healthcare data.
Significant safeguards can be:
- Data Encryption in Storage and in Transit
- Data Access Controls
- Data Access Authentication
- Data Access Control Logs
- Data Developed in Secure Development Environments
- Data Minimized
- Periodic Security Evaluations
- Data Backup and Recovery
- Data Breach Response Plans
Healthcare Data should be Protected and Restricted to the minimum required for the specific task. Collection and Exposure of additional data increases Privacy and Security Risks.
Model Drift in Healthcare
Model Drift describes when a model performs significantly differently in the real world from when it was first deployed. This can happen when the Patient Data Clinical Outcome Interfacing Model no longer holds true.
Bias and Fairness
Modeling inequity is a risk if the data used to develop a healthcare model is inequitable. This inequity may stem from incomplete records, historical inequities, poor labels, or poor feature selection.
Fairness testing measures equity in model outcomes. Privacy and legal obligations should be observed while analyzing model outcomes within patient groups. If fairness is not observed, model error should be analyzed to determine the risk of inequitable outcomes.
Bias, fairness, and accountability are of high concern throughout the system life cycle. Human oversight is required and should be prioritized when model outcomes impact diagnosis, treatment, and the prioritization and provision of healthcare resources.

Challenges of Implementing MLOps in Healthcare Sector
The greatest barrier to adopting MLOps in the healthcare sector is the disparate nature of data. It is common for health data to be inconsistent due to a lack of unified standards and quality.
Other common barriers are:
- Inconsistent data and unstandardized information
- Low quality of available data and high data protection
- Difficulty embedding models in clinical workflows
- Insufficient collaboration between the technical and clinical teams
- Difficult and lengthy approval processes
- Inadequate systems for monitoring models
- Unreasonable risk due to models with low trust and high complexity
- Lack clarity on accountability and responsibility for the models
Successful implementation of MLOPs beyond governance and accountability frameworks will rely on the best practices of other sectors and on automation.
Best Practices for Healthcare MLOps
Before developing healthcare models, the model purpose, users, limitations, and definitions of success and acceptability should be clearly articulated.
Comprehensive documentation of full data lineage should be maintained. Deployment and each model iteration should be reviewed. Automated frameworks should be employed to streamline clinical review and models’ security and privacy assessments.
Organizations should also:
- Distinguish between development and production environments
- Validate models with the appropriate patient populations
- Continuously track and evaluate performance
- Set notifications for anomalous behaviors
- Ensure rollback procedures are in place
- Safeguard patient data
- Periodically reassess fairness
- Educate clinical personnel
- Document human overrides with rationales
- Develop a response system for escalating incidents
In regard to model transparency, users should be made aware of the purpose, applicability, and constraints, as well as the instances where the model should not be relied upon exclusively, and clinical judgment should supplement the model.
Conclusion
Employing MLOps in healthcare creates the framework for transitioning machine learning models from the test phase to incorporation in the real world in a safe and consistent manner. Throughout the lifecycle of a model, MLOps facilitates the management, validation, and controlled use of data, as well as the continuous tracking and governance of the model.
Given the impact that the use of a model can have on a patient, MLOps in healthcare demands that the accuracy of a model be but one of the many considerations. MLOps in healthcare offers the collaboration of not only data scientists and software developers, but also personnel who specialize in securing systems, as well as clinicians and those who manage healthcare practices. Organizations can harness the power of machine learning with strong oversight, documentation, and privacy and responsiveness while minimizing the operational, moral, and patient-safety concerns associated with the increased use of machine learning.
