Chatbot for Medical Diagnosis

Have you ever caught yourself turning to “Dr. Google” when you felt a bit off?
According to the National Center for Biotechnology Information (NCBI), a significant number of Americans—more than a third—self-diagnose, while 70% seek online health advice. What role then, do AI and medical Chatbots play in this evolving landscape?

In this guide, we’ll cover:

  • The basics of medical Chatbots.
  • The difference between Structured vs AI-powered medical Chatbots, and how they work.
  • The future of AI and automation in healthcare.
  • Step-by-step creation of medical Chatbots.

What are medical Chatbots?

Medical Chatbots are interactive software programs designed to automate conversations with patients, providing healthcare-related information and assistance.

These Chatbots can be of two types: Structured medical Chatbots and AI-powered medical Chatbots. The choice between the types of Chatbots depends highly on the requirement of the healthcare provider, the problem they’re trying to solve, and the level of engagement needed from the patient.

1. What are structured medical Chatbots?

Structured medical Chatbots function on structured flows, meaning they follow specific, pre-set rules to interact. They are great for straightforward tasks like filling out forms or providing exact medical details. These Chatbots excel at giving reliable answers, but are limited in their capacity to handle complex queries or provide personalized assistance.

2. What are AI-powered medical Chatbots?

AI-powered Chatbots, such as Tars medical Chatbots, use the strengths of both technologies—structured flows and Generative AI models. By using this hybrid approach, medical Chatbots can handle a wide range of tasks, including symptom assessment, disease diagnosis, appointment scheduling, patient education and more.

These Chatbots become Healthcare AI Agents who can adapt and learn from interactions, offering personalized responses and a wider range of capabilities.

The workings behind AI Chatbots at Tars consist of three prominent models. Let’s explore them with the scenario of a patient who wants to go to an ENT clinic:

  1. Q&A Model: This allows the medical Chatbot to answer FAQs, automate repetitive conversations, and assist in informing patients, e.g. “Can I just walk into the clinic or do I have to book an appointment in advance?” or “Is there a fee to reschedule my appointment?”
  2. Intent Detection Model: Helps the Chatbot understand the intent and context of user queries. For example, if the patient types, “I’ve had a sore throat for almost a week,” the Chatbot will understand that the patient might want a diagnosis of the symptom or to book an appointment with a doctor.
  3. Extraction Model: It converts natural language into structured data, which can be used to facilitate administrative purposes. For example, if the patient says, “I need to know how much a throat swab test will cost at your clinic,” the model identifies and extracts key details like ‘throat swab test’ and ‘cost’ and quickly provides the right information from clinic’s records.

These models ensure that medical Chatbots are equipped to exceed expectations and assist patients. But, while AI medical Chatbots have the potential to revolutionize patient care, there are some myths around the future implications as well. Let’s take a data-driven approach into the future of AI in healthcare.

What are the future implications of AI in healthcare?

AI has made big strides in recent years, impacting industries across the globe, and the healthcare industry is no exception. There’s a vast demand for reliable health information, a gap that is being increasingly filled by AI:

  • IBM highlights how AI can halve healthcare costs and boost outcomes by 40%.
  • Additionally, NCBI research reveals that 78.4% of survey participants (n=476) are open to using ChatGPT for self-diagnosis.

The growing trust in AI underscores its potential impact on healthcare, making AI a significant part of the future of healthcare industry. But too much trust is not a good thing either, because AI is yet to evolve to a stage where it can reliably do what doctors do.

Myth-busting: Can AI medical Chatbots replace doctors?

While Chatbots cannot replace human doctors, they can play a crucial role in assisting with disease diagnosis. Medical Chatbots are equipped with vast databases of medical knowledge and utilize sophisticated algorithms to analyze symptoms and provide potential diagnoses.

However, it’s important to note that Chatbot diagnoses should always be validated by medical professionals. Chatbots serve as valuable tools to support healthcare providers and help patients make informed decisions about seeking further medical attention.

Now, we’ll look more closely at the use-cases of medical Chatbots in healthcare.

Use-cases of medical Chatbots

  1. Symptom Assessment: Medical Chatbots can interact with patients to gather information about their symptoms and provide an initial assessment or advice on the next steps, such as whether to seek professional medical care.
  2. Appointment Scheduling: Chatbots can handle appointment bookings, rescheduling, and cancellations, interfacing directly with hospital or clinic scheduling systems to update availability in real time.
  3. Patient Triage: In emergency or busy settings, Chatbots can help prioritize patient care based on the urgency of conditions, ensuring those who need immediate attention are quickly identified.
  4. Medication Reminders: Chatbots can send reminders to patients about taking their medications, which is particularly useful for managing chronic conditions and ensuring adherence to prescribed treatment plans.
  5. Information Provision: Providing patients with reliable information about diseases, treatments, dietary suggestions, and exercise tips tailored to their health conditions.
  6. Follow-Up Care: Chatbots can assist in follow-up care by sending patients reminders for follow-up visits, post-treatment care instructions, and monitoring recovery progress.
  7. Mental Health Support: Some Chatbots are designed to offer support in managing mental health conditions, providing therapeutic interactions like cognitive behavioral therapy (CBT) techniques.
  8. Health Monitoring: Integrating with devices that collect patient data (like wearables), Chatbots can monitor health metrics (e.g., blood pressure, blood sugar) and alert healthcare providers if the data indicates a need for intervention.
  9. Billing and Insurance Queries: Handling inquiries related to costs, insurance coverage, and billing details, thereby reducing the administrative burden on human staff.
  10. Patient Feedback Collection: Collecting feedback about patient experiences at healthcare facilities to improve service quality and patient satisfaction.

With these use-cases, you can see how versatile medical Chatbots can be in enhancing the efficiency of healthcare services.

How to create a medical Chatbot: A step-by-step guide

Creating a medical Chatbot is easy when you follow a step-by-step process. With the 8 steps described below, you can take a structured approach to building medical Chatbots.

Step 1: Define the pain points and what you’re trying to solve

Determine what problems the Chatbot will solve. Will it help with symptom checking, appointment scheduling, or patient education? Once your objectives and use-cases are clear, outline what you want to achieve with your Chatbot, and how you will measure its success (reducing wait times, improving patient engagement, or automating routine inquiries).

Step 2: Choose a platform for your medical Chatbot

Decide whether you need a rule-based system or an AI-powered Chatbot. This decision will be based on the features, affordability, and practicality of each approach.

User EngagementBasic interactions, requires Live Chat for complex queriesDynamic and conversational
Use CasesSimple tasks (e.g., scheduling)Complex tasks (e.g., diagnosis)
CostGenerally lowerGenerally higher

Next, pick a Chatbot platform that can fulfill your requirements. Ensure that the platform can integrate with your existing healthcare systems like electronic health records (EHR) or customer relationship management (CRM) systems. For example, Tars integrates with your existing frameworks through API Gambit configuration.

Step 3: Design the Conversation Flow

Map out interactions by designing how the Chatbot will interact with users. Start from greeting to potential pathways of the conversation depending on user responses. Thoroughly consider which medical outcomes you would lead your patients to, and ensure that patients do not get stuck in conversational loops.

Step 4: Develop the medical Chatbot

If using AI, train the Chatbot using relevant medical data to update its knowledge base. Ensure compliance with data privacy regulations.

Use the tools provided by your chosen platform to create the Chatbot: this might involve some coding or no-code solutions depending on the platform. Some platforms, like Tars, will initially build the Chatbot for your business needs, and handover the management of the Chatbot to your team.

Step 5: Test and refine your medical chatbot

Before going live, conduct thorough testing internally to check for bugs and ensure the flow works as intended. Your platform might have methods of testing and refining responses such as Tars AI Self Evaluation. After initial testing, gather feedback from a small group of end-users—make necessary adjustments.

Step 6: Ensure compliance and security

Ensure the Chatbot complies with healthcare regulations such as HIPAA in the US or GDPR in Europe, and implement security measures to protect patient data.

Step 7: Deploy the medical Chatbot

Go live with the Chatbot on your healthcare facility’s website, app, or other patient interaction points such as WhatsApp.

Step 8: Monitor and improve your medical Chatbot

Monitor how the Chatbot is performing, what queries it is handling well, and where it might be falling short. Regularly review conversations to identify areas for improvement. Your platform might offer some insights for analysis, such as User Flow Analytics or Live Chat Analytics.

Based on these data-driven insights, keep the Chatbot updated with new information by updating its knowledge base and evaluating its performance.

By following these steps, you can ensure that your medical Chatbot continually exceeds user expectations and helps you provide better healthcare services.
