Human medicine is not the only area where AI can improve something

The medical field is of course not limited to human medicine. AI technologies, which have also started to touch the lives of our cute friends, brought a smile to our faces with the story of Twitter user @peakcooper’s dog’s recovery in March 2023.

Thanks to ChatGPT, Open AI’s chatbot that redistributed the cards in the world of technology, our little friend was saved from a very bad situation due to a misdiagnosis. When Cooper couldn’t see any improvement in his dog despite the treatment, he brought the issue to GPT-4 and told the artificial intelligence about his dog’s test results. The AI successfully differentiated between tick-borne disease and Immune-Mediated Hemolytic Anemia (IMHA), two symptomatically very similar diseases, and saved Sassy’s life.

You can read the whole story in the tweet series below.

I noticed her gums were very pale, so we rushed back to the vet.

The blood test revealed an even more severe anemia, even worse than the first day we came in.

The vet ran more tests to rule out any other co-infections associated with tick-borne diseases, but came up negative 2/

— Cooper (@peakcooper) March 25, 2023

My educational background is based on veterinary medicine and I would like to make a self-criticism here. You cannot always give your patient the attention he/she deserves when he/she comes to your clinic after a long day and this unfortunately has the potential to lead to loss of life, which is defined as human error in medicine. Having a tireless assistant with you is the only thing that can reduce the share of human error to almost zero. The use of artificial intelligence in surgery will certainly reduce the margin of error in such a critical area.

Challenges in the application of artificial intelligence in surgery

As mentioned before, artificial intelligence (AI) has found its way into various fields of medicine and healthcare, including surgery, but its implementation is not without limitations and challenges. It is crucial to shift our mindset from reactive to proactive when it comes to addressing the drawbacks associated with new technology.

Data availability

Collecting data is a crucial initial step in building an AI system. To develop effective models, a significant amount of high-quality data is required. However, data collection raises concerns related to patient privacy and recent incidents of data breaches by major corporations. Technological advancements have increased computational power and data storage capabilities. Technologies like facial recognition and gene analysis enable individual identification from a pool of people.

However, patients and the public have the right to privacy and the choice to determine what data they share. Data breaches pose risks of insurance companies accessing patient data, potentially resulting in the denial of medical insurance based on genetic composition. Patient privacy restrictions limit the availability of data, leading to limited model training and a failure to explore the full potential of the models therefore it is a hindering factor in the integration of artificial intelligence in surgery.

Creating biased models

Artificially intelligent systems are trained using a portion of the collected data (training data set), with the remaining data reserved for testing (testing data set).

If the collected data is biased, targeting specific races, genders, or age groups, the resulting model will also be biased. It is crucial that the collected data represents the intended population without bias.

Data preprocessing

Even with unbiased data, it is possible to create biased models. Raw data often contains errors due to manual data entry or other factors.

Preprocessing is required to prepare the data for algorithm training. However, care must be taken during data preprocessing to avoid introducing biases into the data set.

Model selection

With numerous algorithms and models available, selecting the most suitable one for a specific task is essential. The process of model selection plays a critical role in the integration of artificial intelligence in surgery. Biased models are often oversimplified and fail to capture the trends present in the dataset.

Presenting biased models

Users of AI systems must have a basic understanding of how models are built to interpret the output effectively and determine its applicability. Metrics such as:

• Accuracy
• Precision
• Recall
• F1 score
• AUC score

Are used to evaluate model performance.

However, not all metrics are suitable for every problem. Users need to ensure that the appropriate metrics are presented and not just those with the highest scores.

Fragmented data

One limitation of AI applications, especially artificial intelligence in surgery, is the inability to seamlessly transfer models designed and deployed by one organization to another without recalibration.

Due to privacy concerns, data sharing between healthcare organizations is often limited, resulting in fragmented data and reduced model reliability. That is why the usage of artificial intelligence in surgery is not common as of 2023.

Blackboxes

AI systems are often regarded as blackboxes due to the complexity of the underlying mathematical algorithms. Efforts are being made to make models more accessible and interpretable, but there is still progress to be made in this area.

Considerations on artificial intelligence in surgery

The integration of AI with interventional and surgical specialties raises numerous ethical concerns, particularly regarding bias and accountability. These ethical issues become even more significant as we move towards fully autonomous operations. Self-directed AI-initiated responses or interventions present particular ethical challenges. As previously discussed, datasets used to train AI systems can be inherently biased, which can lead to diverse downstream impacts in different patient subgroups. This means that interventions and outcomes may vary among patients.

To illustrate this, let’s consider cosmetic surgery. AI can now predict an individual’s age by analyzing facial features and suggest surgical steps to reduce signs of aging. In South Korea, where cosmetic surgery is prevalent, surgeons utilize motion-sensor surgical instruments that collect real-time data and guide them in making precise adjustments to improve outcomes. However, these AI algorithms carry inherent biases. In 2013, the Miss Korea pageant sparked controversy due to the resemblance of facial features among contestants who had undergone cosmetic surgery. Beauty is subjective, and when artificial intelligence dictates aesthetic standards, the complexity deepens. It is evident that such AI algorithms cannot be universally applicable across different communities and ethnicities.

In a surgical environment, there is much at stake. If an AI-trained robot malfunctions or loses control during a procedure involving intricate tasks like dissection, suturing, or manipulating catheters in the heart, it can have catastrophic consequences. The extent of AI involvement directly correlates with the ethical concerns at hand. Training robots with datasets encompassing thousands of procedures performed in diverse conditions, sites, and by multiple operators becomes crucial in mitigating harm. However, when harm does occur, determining responsibility becomes a challenge. Should it lie with the company that developed the autonomously operating robot, the surgeon, the hospital, or those who contributed to the dataset?

AI is unable to replicate the decision-making process surgeons rely on, which often involves gut instinct and draws upon unquantifiable clinical experience. Moreover, a single surgical operation entails thousands of intricate steps, including cutting, dissecting, connecting, burning, cooling, clamping, ligating, and suturing. In the foreseeable future, robots will only serve as assistants. While they may become more proficient in basic functions, the addition of more complex layers will require careful consideration and implementation, as the surgeon’s expertise and judgment remain irreplaceable.

Misconceptions about AI in healthcare

Despite all these concerns, there is a great deal of optimism surrounding the potential of AI to revolutionize the healthcare sector in various ways, encompassing patient diagnosis, prognosis, drug discovery, and assisting physicians to provide a more personalized experience for patients. This optimism has been fueled by the successful applications of AI in healthcare. However, alongside this, there are unrealistic expectations about the capabilities of AI and how it will shape the future of the healthcare industry.

Dr. Anthony Chang, a speaker at the 2019 Society for Artificial Intelligence in Medicine (AIME) conference, delivered a lecture titled “Common Misconceptions and Future Directions for AI in Medicine: A Physician-Data Scientist Perspective” in Poznan, Poland. In his lecture, he addressed two prevailing myths related to the implementation of AI in healthcare.

Myth 1: AI will replace clinicians

While the future cannot be predicted with certainty, physicians who possess an understanding of the role of artificial intelligence in surgery are likely to have a competitive edge in their careers.

For example, the American College of Radiology (ACR) posted a job advertisement for a Radiologist, outlining two requirements:

1. Must be American Board of Radiology Certified
2. Must be an enthusiastic, well-trained radiologist excited about a future where radiologists are supported by world-class AI and machine learning

Myth 2: Programming knowledge is essential for utilizing AI

AI adoption in any field involves multiple components, and programming is just one aspect. For artificial intelligence in surgery to continue growing, developing, and succeeding, physicians and data scientists must collaborate closely to construct meaningful AI systems. Physicians need to comprehend AI’s potential and assess how it can enhance their roles, effectively communicating this information to data scientists who can then build the AI system.

Collaboration does not end there. Physicians and data scientists must jointly determine the available data for model training, analyze and interpret the model’s performance, requiring ongoing collaboration. Additionally, there is a growing trend of AI software becoming more accessible and user-friendly, such as visual tools like Google’s Teachable Machine, which enable building visual classifiers without coding skills.

By harnessing the power of AI, healthcare can transition from a one-size-fits-all approach to a personalized and patient-centered model, improving health outcomes and enhancing the overall healthcare experience for individuals. Artificial intelligence in surgery and healthcare will be the technology that will open the doors to the bright future that awaits us all.
