Ambient AI Scribe (Voa Health) in Outpatient Clinics: Draft Notes, Documentation Burden, and Well-Being

The goal of this randomized clinical trial is to learn whether an "ambient AI scribe" (Voa Health) can reduce documentation burden and improve physician well-being and patient experience in outpatient clinics. The AI scribe listens to the audio of the consultation and produces a draft of the clinical note that the physician reviews and edits. In this study, consultations are randomized to 2 groups: usual documentation (without AI) or documentation assisted by the AI scribe. Adult patients seen in participating clinics, and their physicians, are invited to take part. For both groups, the consultation audio is recorded and, at the end of the visit, physicians and patients complete short questionnaires about well-being, workload, communication, empathy, and satisfaction. The questionnaires are based on internationally used scales (such as PFI, Mini-Z, NASA-TLX, CARE, PSQ-18, and CAT) but adapted to keep them brief and feasible in routine care. The main questions are whether the AI scribe lowers the time and effort needed to document the visit, improves physician professional fulfillment and reduces burnout, and whether it affects how patients perceive the communication, empathy, and overall quality of the consultation. No drugs or devices are being tested. The results are expected to guide hospitals on the safe and effective use of ambient AI scribes in real-world clinical practice.

Voice Assistant for Outpatient Neurology Visits

Documentation duties account for a substantial portion of an outpatient physician's working time and reduce time available for direct patient interaction. Voice assistants based on automatic speech recognition and large language models are being developed to automate medical documentation across clinical specialties. However, such ambient AI-based services have not been systematically validated in Russian-language outpatient neurology practice integrated with a regional electronic health record platform. This pilot, multicenter, prospective, before-after study evaluated the feasibility and preliminary effectiveness of a voice assistant Service designed to automatically pre-fill the structured outpatient neurology visit protocol in the Moscow regional medical information system (EMIAS). The Service implements a pipeline of streaming speech-to-text transcription, two-speaker diarization, and large language model-based mapping of the dialogue between the physician and the patient onto the fields of the standardized neurology examination protocol. Five neurologists at five outpatient clinics in Moscow participated. The study comprised three stages: (1) baseline timing of consultations without the Service; (2) timing of consultations with the Service after a two-week adaptation period, with parallel evaluation of transcription and pre-fill quality and of physician and patient satisfaction; and (3) statistical analysis. Three hundred twenty consultations were timed (160 per stage). A stratified random sample of 30 audio-recording / generated-protocol pairs was used to evaluate Service quality; free-text fields were rated on a 5-domain Likert questionnaire and on a 10-point visual analogue scale, and binary fields were rated dichotomously to derive sensitivity, specificity, accuracy, Jaccard index, and false-positive rate. Patient satisfaction was assessed by the modified Patient Satisfaction Questionnaire 8 (PSQ-8); physician feedback was assessed by a custom questionnaire (including the Net Promoter Score) and by semi-structured in-depth interviews with thematic analysis using grounded theory. The primary outcomes were the change between stages in (a) the time of focused physician attention to the patient and (b) the time spent filling and editing the protocol. Secondary outcomes addressed total consultation time, transcription quality (Word Error Rate), expert-rated quality of pre-filled fields, patient satisfaction, and physician satisfaction. The study was conducted under the framework of the Moscow Healthcare Department experiment on the use of digital innovation technologies in health care (Order No. 153 of 21 February 2025), and was approved by the local independent ethics committee.
