Why?
AI is rapidly filtering into real-world healthcare, yet its implications are not commonly considered. This lesson builds understanding on how AI is transforming medical practice, along with ethical dilemmas around its usage, through accessible cases and activities. Students analyze promises and perils of emerging tech on their own health, gaining critical faculties to evaluate AI responsibly. Discussing this topic develops appreciation for technology’s benefits and builds wisdom to guide innovation for human enrichment.

Case Study
Distribute or read Case Study handout.
Summary: In a remote village’s medical clinic, an AI diagnostic tool is implemented to assist with identifying illnesses, showing efficiency in over 200 cases. However, a misdiagnosis of a severe case, where the tool and the doctor identify a boy’s appendicitis as gastritis, leads to community distrust in the technology after the boy’s condition worsens, requiring emergency surgery. The incident sparks debates about the reliability of AI in healthcare and presents the clinic with the challenge of rebuilding trust in the technology among the villagers.
Student Handout
Case Study: AI in Medical Diagnostics
The remote village of Mazpisāni (population 2,000) in a rural location has a small medical clinic run by Dr. Anna Singh. Recently, the clinic started using an AI diagnostic support tool called Medic-Searcher to help identify illnesses and make treatment recommendations. The tool was donated through a non-profit health organization.
So far, Medic-Searcher has helped Dr. Singh efficiently diagnose over 200 cases this year alone. However, this week a crisis hit when 10-year-old Joma Nuki came in with severe abdominal pain. Medic-Searcher analyzed his symptoms and categorized it as “likely gastritis.” Dr. Singh agreed and told Joma’s mother to give him fluids, let him rest and take pain medication as needed.
Two days later Joma’s pain was even worse. His parents walked for miles to take him to the nearest full hospital, where scans showed his appendix had ruptured. He required emergency surgery and a lengthy hospital stay to recover.
The Nuki family was devastated that the seriousness of Joma’s condition was missed. Rumors circulated questioning the clinic’s care, claiming the AI technology was unreliable. Several village elders convened community meetings to debate getting rid of Medic-Searcher given this egregious misdiagnosis. Parents now say they have lost trust in the AI system.
Dr. Singh insists the technology has greatly aided village healthcare overall. But regaining patient and community trust around Medic-Searcher presents a major challenge she must now resolve.
Questions
- What steps could you take to rebuild trust in the AI technology among the villagers?
- How can you communicate the benefits, while also working to fix the problems created?
Simulation
In this simulation, students take on the roles of a medical professional, an AI diagnostic tool, and four patients. Students could do this in groups of six, or one set of six students could role play while the rest of the class looks on.
Distribute the handouts to people involved in the simulation:
- Medical Professional: Two pages, including the diagnosis page and the list of symptoms organized by possible conditions
- AI Medical Diagnostic Tool: Page of AI Diagnoses
- Patients (#1 – #4): Page of Patient Symptoms
- Have the Medical Professional read the introduction on the page so the group knows the role.
- Each Patient comes to the Medical Professional’s clinic one at a time.
- Patients present symptoms. As symptoms are presented, the Medical Professional looks at the list of symptoms and possible conditions. The Medical Professional makes an educated diagnosis and writes it on the page.
- After writing a diagnosis, the Medical Professional checks with the AI diagnostic tool, which has the AI diagnoses listed on a handout.
- The Medical Professional may ask the AI diagnostic tool for explanations for the diagnosis. This simulates the process of inputting information into an AI chatbot and then asking it follow-up questions.
- The Medical Professional should write the AI diagnosis on the page as well.
- After all four patients have visited and diagnoses recorded, go over the sheet one patient at a time.
- State the Medical Professional diagnosis, and the AI Diagnostic Tool diagnosis. Then provide the following Correct Diagnoses for all four patients:
Patient 1: Tuberculosis (AI will be correct on this diagnosis)
Patient 2: Alzheimer’s Disease (AI will be correct on this diagnosis)
Patient 3: Rocky Mountain Spotted Fever (AI will be incorrect on this diagnosis)
Patient 4: Multiple Sclerosis (MS) (AI will be correct on this diagnosis)
- In groups, have students consider the outcomes. How did they feel when the human doctor was right (or wrong)? How did they feel when the AI diagnostic tool was wrong?
- Bring the students back for whole-class discussion.

Simulation – Medical Professional
At your rural medical clinic, several patients have arrived with different symptoms. You are trained as a general practitioner, but you do not have understanding of every possible condition people could have. You do have the assistance of an AI medical diagnostic tool called Medic-Search. This tool is intended to help humans in diagnosing medical conditions, and has been shown to be 95% accurate. Human physicians at big hospitals have other practitioners to consult about confusing symptoms. You are limited in your access to human doctors, so Medic-Search has been very helpful for you.
As patients arrive, listen to their symptoms. Look at your list of conditions and try to match up the symptoms with a diagnosis. Write down your diagnosis for each patient. After each patient is done with the appointment, consult Medic-Search as well. Write down Medic-Search’s diagnosis.

Simulation – AI Diagnoses
You are representing Medic-Search, an AI diagnostic tool. You provide these diagnoses when asked by the medical professional. Do not offer any explanation unless asked for it.
Person #1 – Tuberculosis: High fever (103 F), difficulty breathing, frequent cough (with blood present), chest pain when breathing deeply, fatigue, and night sweats are all classic symptoms of Tuberculosis (TB).
The history of smoking and exposure to dust/chemicals in a manufacturing facility could have compromised lung health, making the individual more susceptible to TB.
Person #2 – Alzheimer’s Disease: The symptoms described, including sporadic short-term memory loss, difficulty learning new tasks and recalling words, confusion, and mood/personality changes, are hallmark signs of Alzheimer’s disease.
The significant family history with the mother having Alzheimer’s disease and the maternal grandmother showing dementia symptoms strongly suggests a genetic predisposition to Alzheimer’s.
Person #3 – Lyme Disease: The symptoms of fever, headaches, and a rash spreading from the trunk to the face and limbs are indicative of Lyme disease, particularly the rash which often resembles a “bull’s-eye” pattern.
The recent camping trip and the mention of several bites are crucial context clues. Lyme disease is commonly transmitted through tick bites, which are more likely to occur during activities like camping.
Person #4 – Multiple Sclerosis: The symptoms described, including vision disturbances (especially peripheral vision loss), occasional double vision, weakness, and lack of coordination, are common in Multiple Sclerosis.
The presence of MS in a close family member, such as a sister, significantly raises the likelihood of MS as a diagnosis due to the genetic component associated with the disease.

- What challenges do doctors face when diagnosing a patient based on symptoms? How might these challenges affect patient care?
- What are the benefits of using AI for medical diagnostics in this context?
- What are some potential dangers of using AI? How is it different?
- What ethical considerations are involved in relying on AI for healthcare?
- Could an AI diagnostic tool with a 5% inaccuracy rate be seen as worse than a human doctor with the same inaccuracy rate? How so?
- What can be done to improve trust in AI-driven healthcare tools?
- If an AI diagnostic tool makes an error, who should be blamed? Doctors who accepted the diagnosis? Programmers? Patients?
- If you were a patient, how would you feel about the diagnostic process? Would you trust an AI tool, a doctor, or both?
- How do you think advancements in AI and technology will change the way diseases are diagnosed in the future?
- Is a reliable AI tool likely to cause hospitals to have fewer trained doctors on staff? Could there be a situation where a hospital has fewer doctors because the AI does their job?
