ESO Electronic Health Record (EHR) makes it easy to produce quality EMS clinical documentation. Yet it's so advanced, it actually gives you back more data than you put in. Say goodbye to your old ePCR. And say hello to ESO EHR. From Incident to Signature, ESO Makes it Easy to Produce Quality Clinical Documentation. At ESO, we understand EMS like nobody else. We’re more than a vendor — we’re a partner that’s helping move the EMS profession forward. That’s why we designed EHR the way we did: It’s intuitive to use, so you can move from incident to signature quickly and while capturing the right information. EHR is more than a documentation tool — it’s a reference tool that helps you make better patient-care decisions in real time. Features such as patient lookup, specialty patient forms and integrations with Handtevvy and Quick Speak put the power in your hands to deliver the best in care.
