PowerChart is an electronic health record (EHR) system used by hospitals and health systems to manage patient information, place orders, document clinical notes, and coordinate care. Originally built by Cerner Corporation, it became part of Oracle Health after Oracle acquired Cerner in 2022. It holds roughly 19% of the U.S. hospital EHR market, making it the second most widely used inpatient EHR system in the country.
How PowerChart Works
At its core, PowerChart is a centralized digital chart for every patient in a hospital or clinic. Clinicians use it to review lab results, vital signs, imaging reports, and documents all in one place. They also use it to place orders for medications, lab tests, and procedures, and to write clinical notes like progress notes, operative notes, and discharge summaries.
The system is built on the Cerner Millennium platform, which connects PowerChart to other clinical applications. For example, SurgiNet handles surgical workflows and FirstNet supports emergency departments, but all feed into the same patient record that PowerChart displays. This means a surgeon, an ER physician, and a primary care doctor can all access the same chart without switching between separate systems.
Built-In Safety Features
PowerChart includes clinical decision support tools designed to catch errors before they reach a patient. These include drug interaction alerts that flag dangerous combinations when a provider enters a new prescription, drug-allergy warnings, duplicate testing alerts, and dosing calculators. The system can also surface reminders for preventive care like immunizations or cancer screenings, and it provides condition-specific order sets so providers don’t have to build routine orders from scratch every time.
These aren’t just pop-up warnings. The decision support layer also includes things like severity-of-illness scoring, diagnostic suggestions based on patient-specific data, and formulary guidelines that help providers choose medications covered by a patient’s insurance.
Specialty-Specific Workflows
PowerChart isn’t a one-size-fits-all screen. Hospitals can configure different views based on a clinician’s role, department, or the patient’s condition. An oncologist, for instance, can use a dedicated staging page that pulls data from pathology and radiology reports and automatically calculates a cancer stage. A nurse on a medical floor sees a different layout than a pharmacist reviewing medication orders.
These customized views are built using a feature called MPages, which lets organizations group relevant information onto a single screen to match a specific workflow. Hospitals can modify existing templates or create new ones, so the system reflects how their teams actually work rather than forcing everyone into the same interface.
Mobile Access With PowerChart Touch
PowerChart Touch is the mobile version of the system, designed for use on smartphones. It lets clinicians review patient data, write notes, place most types of orders, sign documents, and check messages without logging into a desktop computer. You can also take photos with your phone’s camera and upload them directly to a patient’s chart.
The app includes an in-app dictation feature for faster documentation and a physician handoff tool for managing patient transitions between shifts. With handoff, you can review and update illness severity, enter a patient summary, and create action checklists. There are some limitations: medication orders that require dosing calculators can’t be placed through the mobile app, and order sets aren’t supported.
Data Sharing With Other Systems
Hospitals rarely operate in isolation, and PowerChart supports data exchange with outside systems using interoperability standards. The most significant of these is FHIR (Fast Healthcare Interoperability Resources), a protocol designed to work across all major EHR platforms. FHIR improves on older data exchange methods by combining previous standards into a more flexible framework that makes it easier to pull in information from other health systems, registries, and health information exchanges.
In practice, this means a provider using PowerChart can potentially view records from a patient’s visit at a different hospital system, or share data with public health agencies and specialty registries without manual re-entry.
Oracle’s Acquisition and What Changed
When Oracle acquired Cerner in 2022, the company rebranded the division as Oracle Health. The goal was to combine Cerner’s clinical tools with Oracle’s cloud infrastructure, analytics, and automation capabilities. Oracle has since introduced AI-powered features under the name Oracle Health Clinical AI Agent, designed to automate tasks like appointment preparation and clinical documentation to reduce the administrative burden on providers.
For hospitals already running PowerChart, the transition has been gradual. The core product still functions as it did under Cerner, but Oracle is building a next-generation EHR that embeds AI more deeply into clinical workflows. Whether that eventually replaces PowerChart or evolves from it remains an open question for existing customers.
Who Uses PowerChart
PowerChart is used primarily by hospitals, large health systems, and academic medical centers. With nearly 19% of the U.S. hospital EHR market, it’s found in a wide range of settings, from community hospitals to major research institutions. The system serves physicians, nurses, pharmacists, lab technicians, and administrative staff, though each group typically interacts with a different set of screens and tools tailored to their responsibilities.
If you’re a new employee at a hospital that uses Cerner or Oracle Health, PowerChart is almost certainly the application you’ll open most often. Training programs vary by organization, but most hospitals provide role-specific orientation covering the views and workflows relevant to your position.
