The new standard for OR intelligence

Apella’s computer vision models analyze live video from ceiling-mounted cameras to autonomously detect and timestamp 14 key events across surgical cases and turnovers — ranging from basic patient entrance and exit to more granular events EHRs typically do not capture, including draping, cleaning start, and room setup start — grouping events into distinct and relevant case phases, and can write back to the EHR, including Epic, reducing manual documentation for staff.

Yes. Apella works alongside the EHR, including Epic and Oracle Health - Cerner, enriching documented information with objective OR data captured through computer vision. By integrating ground-truth events with EHR records, Apella’s predictive models generate more accurate forecasts and a trusted, end-to-end view of the schedule. Key events can be written by Apella back to Epic, improving operational data accuracy without adding staff overhead or documentation.

Apella's computer vision detects perioperative events in seconds, capturing wheels-in an average of 11x faster than the EHR, which can take up to 19 minutes, and wheels-out an average of 14x faster than the EHR, which can take up to 20 minutes. Using Apella, hospitals have improved case duration accuracy by 40%, with mean error falling from 57.4 to 34.2 minutes. Apella’s schedule forecasts are 24% more accurate than the EHR.

Yes. Apella's ambient AI was evaluated in an independent, peer-reviewed study published in BMJ Health & Care Informatics, where F1 scores for detected perioperative events exceeded 0.98 — a level of accuracy, precision, and recall the study characterized as "decision-grade," meaning it's reliable enough to drive real-time operational decisions rather than just supplement them.

Unlike tools like LeanTaaS iQueue and Qventus, Apella uses computer vision to capture ground-truth observations directly from the OR instead of relying exclusively on manually-entered, hard-to-trust EHR data. Apella’s platform brings together tools for day-of coordination, scheduling, and performance analytics in a single, connected system, all powered by the same trusted data foundation.

Apella is purpose-built for OR and procedural operations — unlike Artisight's hospital-wide smart room platform, Proximie's surgical telepresence and video tools, or Aimbient's origins in OR Black Box–style retrospective safety recording. Apella predicts case duration in real time and can automatically write up to 14 event timestamps back to Epic, validated with a 98% F1 score across 500,000+ cases. Only Apella has independently validated its impact with a 7% increase in surgical case volume according to a peer-reviewed study by Houston Methodist published in the Journal of Imaging.

Yes. Beyond operating rooms, Apella's technology can also be used in other anesthesia rooms like interventional radiology, cardiology, and endoscopy. Its models can be trained on data from a broad range of procedure types specific to a partner health system’s objectives.
