How to mitigate AI bias in Healthcare Applications?

Artificial intelligence is increasingly influencing many aspects of our existence, which is incredibly beneficial for the environment. It also finds exciting uses in healthcare. Medical institutions have started upgrading their infrastructure in reaction to technological advancements. However, keep in mind that algorithms are trained on inadequately diversified data, which might result in data bias in AI. With medical institutions embracing more and more technological innovation, including AI, this prejudice may unintentionally contribute to rising healthcare inequities.

Healthcare organizations must make a concerted effort to mitigate AI bias in healthcare applications because a biased AI model can seriously harm patients’ health and well-being. But, how can we prevent algorithmic bias in healthcare?

Keep reading to find the solutions for avoiding AI bias in healthcare.

What is bias, and how does it affect patient well-being?

The problem of algorithmic prejudice is not new. An algorithm is just a series of phases in reality. Any healthcare problem, including algorithmic bias, is a matter of values: Which healthcare outcomes are essential to society, and why?

Treating algorithmic bias as a technological problem will spawn engineering solutions, such as how to exclude particular fields from data, such as race or gender.

A biased AI solution frequently results in inaccurate diagnoses and patient care recommendations. Any artificial intelligence-powered solution begins with data. However, healthcare data is fraught with privacy and security concerns. According to a recent study, organizations that exchange medical data are more likely to lose patients than those that keep their patient data personal. This makes it incredibly difficult for solution developers to collect the required data to construct an effective AI model, resulting in poor quality solutions that frequently produce mistakes during diagnosis.

How does AI become biased?

The bulk of algorithmic bias causes falls into two basic categories: subgroup invalidity and label choice bias.

Invalidity of Subgroups

Subgroup invalidity arises when AI models are trained on non-diverse populations or with data that misrepresents or fails to incorporate unique risk factors influencing them.

Bias in Label Selection

Label selection bias is more prevalent and difficult to detect than subgroup invalidity. It happens when the algorithm’s anticipated outcome is a proxy variable for the actual outcome it should predict. Using cost as a proxy to allocate additional resources or attention exemplifies this bias. This reduces healthcare expenditures while considerably skewing cost as a proxy for future health demands.

Ways to mitigate bias in healthcare applications

Artificial Intelligence bias in healthcare is unavoidable. Organizations are taking significant steps to guarantee that AI is neutral, fair, and understandable. A few key points to keep in mind while resolving Artificial Intelligence bias in healthcare are:

Evaluate algorithms for bias

Examine the AI models in your inventory for label choice bias and subgroup invalidity by carefully examining the data utilized, potential differences with the ideal expected outcome, and factors employed, if possible.

Retrain or discontinue a biased model

To reduce label choice bias, retrain the model with the same variables you used to demonstrate the presence of bias as your new composite result. Models must also be retrained regularly to prevent becoming biased over time. This is caused by feature drift, which happens when the distribution of AI variables in the target population begins to diverge significantly from the distribution in the training population.

Make a concerted effort to ensure impartiality.

Several aspects must be considered when seeking data sets to train your algorithm on. Be careful to take these things into account to maintain justice across diverse groups of the community. Adjusting criteria inside the model to guarantee equitable results and distribution of healthcare resources might be a practical approach.

Obtain patient and healthcare professional feedback.

Any new technology is approved only after a detailed feedback analysis from the users. In this case, the patients and healthcare professionals can help. AI bias in healthcare can be encountered and rectified with accurate feedback. To acquire the best input for your model, you must first understand the errors in the output. And should endeavor to correct it.

Make your staff more diverse.

A homogeneous workforce is one of the primary reasons for bias during model building. When hiring your development team, attempt to diversity your force and include employees from diverse demographics. By fostering an inclusive culture, you can take an approach to eliminate bias in healthcare AI.

Bring together the expertise of technological and medical professionals.

Encourage your solution development team and healthcare specialists to collaborate. This will assist you in incorporating a contextual understanding of medical care into your AI solutions. As previously stated, many illnesses appear differently in different ethnic groups and genders. If medical professionals’ expertise is merged, it will be much simpler to anticipate such situations and act accordingly.

Diversify your dataset

If your data sets are of poor quality, the output of your AI algorithm will suffer. This is why for mitigating bias in machines, you must incorporate well-annotated and vetted datasets from all demographic groups.

Conclusion

A rising number of data sources that are continually gathered, communicated, and fed to artificial intelligence systems are transforming healthcare. To be accurate, new technologies must be inclusive and represent the demands of many people.

As AI solutions are becoming increasingly prevalent in healthcare, organizations must take approaches to eliminate bias in healthcare AI. We need better procedures to weigh the dangers and advantages of AI technology if we want to produce an equal healthcare solution. A collaboration between data scientists, healthcare providers, consumers, and regulators can fulfill this goal. To develop an ethical AI ecosystem that will improve medical care, medical institutions and organizations must begin analyzing AI solutions for bias and fairness. This can help mitigate AI bias and provide top-notch medical care to patients worldwide.
