Recommendations
Artificial intelligence (AI) scribe applications are rapidly being adopted in healthcare for generating medical documentation. These tools leverage advanced AI, often integrating with large language models (LLMs) like GPT-4, to transform physician-patient interactions into comprehensive medical notes.
For instance, The Permanente Medical Group (TPMG) reported 3,442 physicians using this technology across 303,266 patient encounters in just 10 weeks, demonstrating a significant shift in medical documentation practices.

Physicians Utilizing AI Scribe Technology in Early Adoption Phase
AI scribes operate by using automatic speech recognition to convert spoken physician-patient interactions into text. This text is then processed by a Large Language Model (LLM), such as generative pretrained transformer 4 (GPT-4), through an application programming interface (API).
The LLM generates a detailed subjective, objective, assessment, and plan (SOAP) note, a draft follow-up email for the patient, and sometimes recommendations, all within minutes. This process significantly reduces the time physicians spend on electronic medical records, allowing more focus on patient care.

The primary advantages of AI scribe technology include improved efficiency, enabling detailed notes and follow-up emails within minutes. Physicians experience increased cognitive freedom, allowing them to focus more actively on patients, enhancing satisfaction through sustained eye contact and better communication.
AI is also immune to distractions, cognitive overload, and fatigue, potentially leading to better quality notes and a more comprehensive capture of clinically relevant information from dialogue.

Despite the advantages, AI scribes present significant limitations and risks. Errors of omission, fabrication, or substitution (hallucinations) can occur, necessitating careful proofreading by the physician. LLMs have unpredictable sensitivity to user input and inherent variability, and they are not constrained by established medical knowledge.
Other concerns include patient privacy and security (HIPAA compliance), potential algorithmic bias (e.g., race, sex, sponsorship), and the challenge of AI distinguishing voices accurately or understanding nonverbal cues.
Addressing AI Hallucinations in Medical Notes
A significant limitation of AI scribes is the potential for "hallucinations" – errors of fabrication or substitution. For example, in an email to a patient for implant removal without capsulectomy, the AI scribe incorrectly stated, "Capsules removed during surgery will be sent to pathology for examination." This detail was explicitly not part of the surgical plan nor discussed. This highlights the critical need for human oversight, as AI may override what was heard with what it "thinks" was intended based on its training data, leading to potentially significant falsehoods in medical documentation.
- AI-generated content can deviate from actual patient encounters.
- Incorrect medical details can be fabricated or substituted.
- Rigorous human proofreading is essential to detect and correct these critical errors.
To mitigate risks and enhance the reliability of medical AI scribes, several recommendations are crucial. Firstly, robust regulatory oversights are needed to protect data privacy, security, and prevent algorithmic bias. Adherence to ethical guidelines and continuous bias correction are paramount.
Secondly, human proofreading of AI-generated notes is absolutely essential. Physicians must always review for errors of omission, fabrication, or substitution. Developers should also focus on improving AI's ability to recognize and customize based on physician style, and better handle complex medical interactions and terminology (e.g., brand names).
