AI Chatbots in Healthcare

AI chatbots are computer programs that use artificial intelligence to simulate human-like conversations. They process natural language inputs to provide information, answer questions, and guide users through complex topics. In healthcare, chatbots can offer instant responses to patient queries, deliver educational content, and support decision-making when medical professionals are not immediately available.

• Natural Language Processing (NLP): Enables chatbots to understand and generate human language effectively.
• Machine Learning Models: Underlying algorithms, such as transformer-based architectures, trained on large datasets.
• 24/7 Accessibility: Provides users with round-the-clock access to basic medical information and guidance.
• Scalability: Can handle multiple concurrent interactions without additional staffing.

• Clarity: Presents complex medical concepts in simple, conversational language.
• Consistency: Delivers standardized information based on up-to-date guidelines.
• Engagement: Encourages users to ask follow-up questions and explore topics interactively.
• Resource Efficiency: Frees healthcare professionals to focus on complex cases by managing routine inquiries.

Evaluating Health Information Quality

To ensure patients receive reliable guidance, educational materials and chatbot responses must be evaluated using standardized tools. Two widely used instruments are the DISCERN questionnaire and the PEMAT-P assessment.

The DISCERN instrument is a 16-item questionnaire designed to judge the trustworthiness and quality of written health information, especially treatment choices. It is divided into three sections: reliability, details of treatment options, and overall quality. Each question is scored from 1 (low quality) to 5 (high quality), allowing a total score that classifies information as very poor to excellent.

The Patient Education Materials Assessment Tool for Printed Materials (PEMAT-P) measures two aspects: understandability and actionability. Understandability assesses whether users can process and explain the information. Actionability evaluates if users know exactly what steps to take. Scoring involves rating each item as agree, disagree, or not applicable, resulting in separate percentage scores for both domains.
