C-SATS vs Proximie (2026)
Both work with surgical video, for different jobs. C-SATS, owned by Johnson and Johnson MedTech, takes recorded procedures, uses AI to remove patient information and segment steps, and returns technique scores from crowd reviewers on published instruments, with expert feedback. Basic membership is free. Proximie connects the operating room live: remote experts, trainees and device representatives join procedures with video, audio and annotation, and its Intelligence Suite detects surgical events with computer vision and forecasts finish times, with a two way EHR connection. Choose C-SATS to score and coach technique after the case; choose Proximie to bring expertise into the room during it.
- Surgeons want technique scored on published instruments after the case.
- You want to start free, with a Basic membership.
- Video should sit in a HITRUST certified library.
- Remote experts or device representatives should join live procedures.
- Case finish times should be forecast for scheduling.
- The platform should connect both ways with the EHR.

Questions buyers ask
How do C-SATS and Proximie handle patient data?
For C-SATS, the hospital or surgeon is the data controller and a Johnson and Johnson affiliate the processor, under a business associate agreement.
The published business associate agreement (section 4.4) lets Proximie de identify protected health information under 45 CFR 164.514 and use it for any purpose, including training its algorithms, and the data processing agreement (clause 11.4) uses anonymized customer data to develop its algorithms. Device companies can draw structured data from real procedures through the Deploy AI use case. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.
Which settings and specialties do C-SATS and Proximie cover?
In C-SATS's case, the platform assesses robotic and laparoscopic surgery with the GEARS and GOALS instruments, and its video library spans more than ten specialties including bariatric, gynecology, urology, thoracic and colorectal; the home page's outcomes analysis covers gynecology, general surgery, urology, urogynecology, gynecologic oncology and colorectal.
For Proximie, the company reports more than 500 facilities in 50 countries and more than 40 device company customers, and the Surgical Suite is available in about 20 percent of NHS hospitals. Because it captures the room rather than one procedure type, specialty coverage follows the hospital. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.
What evidence is published for C-SATS and Proximie?
With C-SATS, the home page's headline figures come from what the company labels an unpublished exploratory analysis: about 3,000 cases across six specialties and 25 procedure groups, comparing surgeons in the top and bottom quartiles of GEARS scores, with confidence intervals and no adjustment for multiple testing.
In Proximie's case, a year long NHS evaluation that began in September 2026 applies one framework across 104 operating rooms and procedure suites at eight hospitals, covering more than 20,000 procedures a year. The throughput figures carry no baseline or period, and the NHS evaluation has no results yet. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.
How much do C-SATS and Proximie leave to the clinician?
Scores come from crowd reviewers and expert surgeons applying published instruments; feedback returns to the surgeon's own dashboard; video sharing stays within the institution and, in some instances, the C-SATS community; and the How it Works page says health systems can see trends and performance across the surgical team. Enterprise licenses cap expert reviews at two a month and quantitative scores at twelve a year per license.
With Proximie, a remote expert advises the surgeon in the room, and the Intelligence Suite feeds dashboards, daily huddles and notifications to perioperative teams and control centers, who decide on schedules, staffing and turnover. The system acts on its own in two places: it sends automated notifications along the care pathway and writes captured data back to the EHR without manual entry. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.
