WhatsApp has become the go-to channel for patient communication, making chatbot selection an important decision for hospitals. Rule-based chatbots are ideal for handling simple, structured queries with lower cost and effort, while AI chatbots are better suited for complex, high-volume, and multilingual interactions. The right choice depends on a hospital’s size, patient volume, and workflow complexity. Many hospitals start with rule-based systems and transition to AI as their needs grow. Ultimately, the goal is to choose a solution that improves patient experience, reduces staff workload, and scales with the organization.
