As we navigate the complexities of modern medicine, the integration of artificial intelligence (AI) promises to be more than a trend. It can be pivotal in the way we understand, diagnose, treat, and manage health conditions. 

This article describes AI companies in healthcare that are reshaping the industry. We will also illuminate the possibilities and challenges in the industry. This way, we aim to foster AI software development for a healthier future. 

 

Big Data and AI in Healthcare

Just a few decades back, surgical rooms were primarily mechanical. They depended heavily on manual processes, limited technological tools, and isolated data. Surgeons and medical teams relied on physical records, basic monitors, and their skills to conduct surgeries. Few considered using digital tech for surgical intelligence. It required collecting and integrating vast data. Consequently, the innovations in medical procedures faced significant constraints. That is why the adoption of AI in healthcare is going slower than expected. 

A World Health Organization report says chronic diseases cause 71% of all deaths. This highlights the urgent need for better healthcare interventions. Enter AI: a tech that uses vast data, from genes to health records. It finds patterns that may elude human doctors. Also, we are nearing a digital age with 40 zettabytes of data. The solution to some of the world's toughest diseases might be in there. We just need to extract insights from this vast wealth of information.

Nota bene: when was AI introduced in healthcare? In 1971, scientists created INTERNIST-1. It used a solid algorithm to diagnose patients. In 1975, the NIH sponsored the first AI in Medicine workshop at Rutgers. (Apr 20, 2023, Cedars-Sinai Staff.)

Here are the top AI applications in healthcare:

  • Increasing diagnostic accuracy.
  • Identifying at-risk patients.
  • Tailoring treatments to individual patients. 
  • Streamlining administrative processes.
  • Facilitating remote patient monitoring.
  • Simplifying drug discovery.
  • Helping manage population health effectively. 

This list is far from complete. Healthcare AI companies continue to innovate despite a decline in funding.

For EHRs, big data plays a particularly important role. 

 

Electronic Health Records

Ask any healthcare professional about their biggest challenge. They will likely mention cumbersome electronic health records (EHR) systems. In the past, clinicians manually recorded observations and patient data, each using their own method. However, the process looks completely different with AI and deep learning. Speech recognition, interactions with patients, diagnoses, and treatment plans are all made more straightforward. Plus, AI documents this data more accurately and almost instantaneously.

Nota bene: Why are well-structured EHRs so important? The answer is - they could save lives. See, countless individuals have undergone cancer treatments. Each patient's experience generates massive amounts of digital data, often exceeding a terabyte. This data includes demographics, lifestyle, and medical history. It also has details about the disease and its treatment. Therefore, it is a valuable resource, ripe for analysis. Many initiatives aim to combine scattered data on cancer patients for a better study. Connecting doctors with this data lets them compare treatments and outcomes for similar cases. It will enable more effective, personalized therapies. 

Preventive healthcare is a goal scientists aim for, and data plays a crucial role in reaching it. EHRs, medical devices, wearables, and admin systems create much healthcare data. This vast scale poses both challenges and opportunities for healthcare professionals.

Let’s focus on opportunities.

 

Combating Cancer

The cost to sequence the human genome is now as low as $2,000. So, industry pros can now test a person's DNA for cancer-related genetic markers. Also, digitizing medical records can help detect cancer symptoms faster. This can lead to more tests. 

Big data analysis also uncovers global patterns. It helps identify high-risk groups and discover potential causes or treatments. Recently, a wide array of variables led to a surprising discovery. Desipramine, a common antidepressant, might treat small-cell lung cancer. 

 

Combating Infectious Diseases

Infectious diseases are ever-evolving. Urbanization, climate change, and global travel drive this change. A rise in online searches for specific diseases may signal an outbreak. Social media can track an illness's spread across regions. With nearly four billion internet users, these platforms hold much potential. They are a rich source of data that AI can analyze. It can then detect patterns of behavior that indicate an epidemic. 

The success of these methods has been mixed. Google Flu Trends (GFT) initially made significant advances in tracking flu outbreaks. However, the H1N1 pandemic caused a surge in global searches. This distorted local data and led to false findings, and operations ceased. 

These methods are still in development. But they can provide key insights for experts to explore.

Challenges of Implementing AI in Healthcare Systems

There’s often a belief that AI is ready for adoption, but that’s not necessarily the case. It may be fine for tasks like weather prediction. But, its use in health care can have life-altering effects. In 2016, Geoffrey Hinton, known as the "godfather" of AI, made an interesting statement. He predicted that radiologists would become obsolete, like typesetters and bank tellers. He claimed that people should stop training radiologists. Within five years, he predicted, deep learning will do that better.

Yet, over five years later, radiologists are still being trained to read scans. Medical experts say AI has not met its high hopes. Health systems are not ready for such technology. Furthermore, the government's regulatory response is still developing.

The FDA list includes 692 devices:

  • Radiology: Comprising 77% of the list with 531 devices.
  • Cardiovascular: Making up 10% with 71 devices.
  • Neurology: Accounting for 3% with 20 devices.
  • Hematology: Representing 2% with 15 devices.

Nota bene: FDA-authorized devices likely are a small portion of AI tools for healthcare. This is because most automated learning applications don't necessitate regulatory review. For instance, predictive tools, including some computer vision models, don't require FDA approval. 

 

Clinical Validation

Researchers at the UNC School of Medicine analyzed data on 500 AI medical devices. They found that nearly half of the FDA-authorized tools lacked public clinical validation data. Despite claims by manufacturers, AI tools for healthcare are untested. Their clinical efficacy has not been evaluated using actual patient data. 

The implications of these findings are manifold. First, it’s clear that mandatory clinical validation studies need to go public before FDA approval. It would build trust in AI among healthcare providers and patients. This research also urges the medical device industry to account for their product claims. AI healthcare startups can boost the integrity of their devices by rigorously validating them. Making the results public would be a big plus. 

In short, healthcare startups should aim toward creating a culture of evidence-based practices.

 

What is the Future of AI in Healthcare

The future of AI in medicine is undeniably intertwined with a shift in patient care. As AI improves, it will play a bigger role in preventive care, diagnosing, and treatment. The ongoing trend toward cloud connectivity pushes collaboration between AI companies. This will help set clear guidelines for smart data processing to further foster AI acceptance. These advances have deep implications. They can improve health and promote health equity.
