Amion Enterprise: Built Around Physicians

How Doximity Built Amion Enterprise: Putting Physicians at the Center of On-Call Scheduling

For decades, on-call scheduling at health systems meant a patchwork of spreadsheets, whiteboards, and disconnected tools, with each department managing its own system and no reliable single source of truth for who was actually on call. For large health systems, that fragmentation was not just an operational headache. It was a patient care risk.

Doximity acquired Amion in 2022 with a clear mandate: take a product already trusted by over 200,000 clinicians and build it into something that could meet the complex demands of enterprise healthcare, without losing what made it work in the first place.

Built on What Physicians Actually Need

Doximity has always been a physician-first company. When it came time to evolve Amion for enterprise use, the team did not start with a feature roadmap. They started with conversations: with emergency department physicians, transfer center leads, and scheduling administrators who understood the real-world complexity of running a multi-hospital system.

Those conversations shaped everything: real-time schedule visibility across locations, flexible filtering by hospital or specialty, and the ability for clinicians to update their own schedules on the fly from any device. The insight was straightforward: on-call scheduling sits at the intersection of operations and patient care, and getting it wrong has consequences.

Scaling Without Sacrificing Flexibility

When a large not-for-profit health system with over 300 care locations came to Amion, they brought a challenge that tested exactly this philosophy. With diverse hospitals, variable hours of coverage, and administrators using different tools across the system, there was no cohesive scheduling solution in place.

Amion worked closely with system leadership and clinical staff to co-develop system-wide call standards and a centralized scheduling infrastructure built for their scale. The result: 463 active schedules across 3,088 unique users and a system that now serves as a true operational backbone.

"Patient care lies at the core of the Amion project. Transparent contact details and clear escalation pathways across all service lines facilitate service integration, promoting timely care, and thorough and safe patient management." said a Chief Triage Officer and Physician Director at one Amion enterprise partner.

When Scheduling Becomes a Clinical Tool

A leading East Coast health system illustrated Amion's clinical impact through its AutoLaunch Protocol, which dispatches ambulances immediately upon transfer request without waiting for confirmation from the receiving hospital. Amion served as the backbone of that protocol, enabling rapid identification and contact of the right clinicians. The results: a 38% reduction in general inter-facility transfer times and a 28% reduction in specialized stroke transfer times.

What Enterprise-Ready Actually Means

Building Amion Enterprise was about removing friction: for administrators managing schedules, for providers who need to find or adjust their assignments, and for clinical teams routing patients to the right care at the right time. Backed by Doximity's platform and the largest network of healthcare professionals in the country, Amion Enterprise is more than a scheduling platform. It is a care coordination tool.
