What is OSCAR Pro?

The short answer

OSCAR Pro is a hosted, commercially supported distribution of OSCAR EMR, run by WELL Health Technologies. The clinical core is the same OSCAR built at McMaster University and released under GPL v2. What WELL adds is managed hosting, a support desk, service level agreements, and patching you do not have to think about.

More than 10,700 physicians across roughly 2,200 clinics use it, a large share of them Canadian family practices, which makes it one of the biggest EMR providers in the country and the largest member of the OSCAR family by a wide margin. When a Canadian clinician says “we’re on OSCAR,” this is usually what they mean.

How it got this big

OSCAR Pro grew by acquisition rather than one clinic at a time. WELL Health bought up the OSCAR Service Providers that used to host OSCAR independently: NerdEMR, OSCARprn, KAI Innovations, OSCARwest, Trinity Health Technologies, MedBASE Software, and Indivica among them.

That history explains a lot of the confusion clinicians run into. If your clinic signed with one of those vendors years ago, you did not change EMRs, but the name on your invoice changed and your support contact moved. You are on OSCAR Pro now.

It also explains the login. Plenty of OSCAR Pro clinics still sign in at a domain named after the vendor they originally bought from, kai-oscar.com being one of the common ones. That is normal, and it does not mean you are on something other than OSCAR Pro.

What you get, and what you pay

OSCAR Pro is OntarioMD certified, interoperable with HRM and OLIS, and monitored around the clock. WELL exposes REST and web services APIs with OAuth authorization, which is why a reasonable ecosystem of third-party tools plugs into it.

Pricing is quote-based and not published. Expect a per-provider monthly fee plus setup, migration, and training, with patient-facing add-ons billed separately.

The chart underneath is still OSCAR

WELL changed the hosting, the support, and the commercial terms. The chart works exactly as it does on every other OSCAR variant: a single free-text progress note for the visit, and the Cumulative Patient Profile holding the standing record across six sections you maintain by hand, one overlay at a time. The OSCAR guide covers that structure in full.

Why it bites harder in a multi-provider clinic

OSCAR Pro averages close to five physicians per clinic, and that changes what a stale CPP costs you.

On a solo panel, an out-of-date problem list is your own problem, and you carry most of it in your head anyway. In a group practice you are reading charts written by colleagues, covering each other’s patients, and picking up someone’s follow-up on a Friday afternoon. The CPP is the handover document, and it is only as good as the last person who had time to update it.

That is the part manual entry breaks first. Everyone intends to keep the CPP current. The clinician running forty minutes behind does not, and the next person to open that chart pays for it.

An AI scribe does not help here. It writes the note, which was never the slow half, and hands the CPP back to you.

Medulla proposes the CPP entries from what was said in the visit, grouped by section, and the ones you accept go into the chart in one click. It takes the postponable work and makes it something you finish inside the encounter, which is what keeps a shared panel honest.

It matters most on a first visit, where nearly everything said is CPP material and a meet and greet runs forty minutes with most of that spent typing. Medulla turns it into fifteen. In a group practice that is also the visit most likely to be handed to whoever has room that week, which is exactly when the record needs to be complete without depending on who took it.

Where Medulla fits

Medulla runs inside the encounter you already have open, on Med Access and Oscar-based EMRs including Oscar Pro, Oscar 19, Juno, Open OSP, and Avaros. No separate tab, and no copy and paste between a scribe and your chart.

Every suggestion is a checkbox you accept or discard, and nothing reaches the record on its own. Because Medulla reads the chart as well as writing to it, billing and diagnostic code suggestions come from what is in the record rather than from the conversation alone.

See it on your own charts. The trial is free for a month with no credit card required.
