Instead of merely assisting with image analysis, the AI could generate predictive models for disease progression, helping clinicians anticipate future outcomes and plan interventions accordingly. This ability to predict and forecast medical conditions could significantly improve patient care by fostering proactive and personalized treatment approaches.
Capabilities of LLMs and Generative AI in healthcare
Below, we will discuss how LLMs and generative AI can revolutionize the healthcare industry, from streamlining workflow and accelerating processes to enhancing patient care, education, and training. So, how AI can be used in healthcare?
Gen AI gives efficiency and time savings
Medical staff is often occupied with patient consultations, diagnostic procedures, treatment planning, and administrative tasks. AI-driven solutions can help healthcare providers to work more efficiently and automate routine tasks. For example:
Streamlined workflow
AI can streamline clinical workflow by integrating with healthcare IT infrastructure. This includes interoperability solutions, smart electronic health record (EHR) interfaces, and workflow automation tools. In this case, AI effectively reduces the need for manual data entry, improving overall productivity within healthcare settings. Through automation and intelligent processing, AI systems optimize the flow of information, allowing healthcare professionals to focus more on patient care rather than administrative tasks.
For instance, there is a tool called DeepScribe that operates by using a microphone, similar to an Amazon Echo, during medical visits. It employs voice recognition and natural language processing to differentiate between the doctor’s and patient’s voices. Through generative AI, DeepScribe can create medical notes in the format typically used by physicians, including sections like chief complaint, history of present illness, past medical history, family history, and social history.
This eliminates the need for physicians to manually transcribe notes, saving them valuable time during patient consultations. DeepScribe is already implemented by Stanford Health Care, Texas Medical Center, Berkeley University of California, and others.
Saving time
Healthcare providers spend a lot of time and resources manually preparing prior authorization requests for insurance companies for medical procedures. What if Gen AI would do this instead?
For instance, Doximity GPT offers a solution that automates the generation of prior authorization letters. Healthcare providers can input patient and procedure information into the platform, and Doximity quickly generates detailed letters tailored to the specific procedure and patient, including clinical justifications and references. This streamlines the prior authorization process, saving healthcare providers valuable time and resources and ensuring timely patient access to necessary medical procedures.
