Early detection leads to fewer hospital visits, less severe treatments, and better patient outcomes. It enables services like remote monitoring and telecardiology, enhances chronic condition care, and reduces costs. There is also potential for ongoing income from devices and subscription services.

Even one study used wearable ECG devices and AI to interpret single-lead ECGs in about 35 seconds after recording, allowing for faster results.

Ethical Considerations In AI Use In The Medical Industry

When medical AI transitions from research to practice, it offers great potential but also presents ethical risks. These risks can impact patient trust, responsibility, rules, and ultimately, the success or failure of your AI projects. Here are some ethical concerns to look for!

1. Accuracy, Misdiagnosis & Patient Safety

Diagnostic errors in medicine are estimated to happen in 5-15% of cases, depending on the specialty. If an AI model makes a mistake in diagnosing a patient or fails to identify a disease, it can harm the patient physically, mentally, and legally. For business leaders, this means they should invest in:

• Validate AI tools with clinical trials and diverse data.

• Continuously monitor model performance post-deployment.

• Establish clear responsibilities among developers, medical staff, and institutions.

2. Bias & Fairness

Bias in training data, like not including enough people from certain ethnic groups, genders, or age groups, can create tools that work well for some patients but not for others. One study showed that when an AI system was biased, its accuracy in diagnosing dropped significantly, going from about 73% to around 61.7% when no explanation was provided.

3. Transparency & Explainability

Patients, doctors, and regulators want to understand why an AI made a specific decision, especially regarding diagnosis or treatment. “Black-box” models make this difficult to see.

Surveys show that many people who are generally positive about AI in medicine still prefer explainable AI and want doctors to oversee decisions. For healthcare institutions, investing in explainability can reduce pushback, increase adoption, and help meet regulatory requirements.

4. Consent, Privacy, & Data Use

Medical AI needs a lot of patient data, often sensitive like genetic data, imaging, and medical histories. How that data is collected, stored, shared, and used must respect privacy laws and ethical norms. Misuse or breaches can erode trust and lead to legal penalties. Also, patients may feel their agency is lost if they are unaware or did not consent to AI-based decisions. Therefore, when using AI systems, adhering to AI governance standards and data security protocols can be the real escape.

5. Trust & Patient Perception

A recent study found that about 65.8% of adults do not trust their health care systems to use AI safely. Additionally, 57.7% of people are worried that AI tools could cause harm. Many patients want to know if AI is being used in their care. They prefer to understand how AI works and want to be sure that a human is overseeing its use.

Future Possibilities of AI in Medicine

AI is already making a big impact, but in the next 5-10 years, it will greatly change healthcare delivery, how we diagnose diseases, create treatments, support clinical trials, and personalize patient care.
