The difference between an EHR and an EMR is:
An EMR (Electronic Medical Record) is practice-specific. An EHR (Electronic Health Record) is designed for interoperability — data can follow the patient across providers.
2 / 15
CPOE (Computerised Provider Order Entry) allows:
CPOE replaces handwritten orders — clinicians enter prescriptions, lab tests, and radiology orders directly into the EHR, improving legibility and enabling real-time clinical decision support.
3 / 15
Clinical Decision Support (CDS) in an EHR provides:
CDS augments clinical decision-making — alerting clinicians to drug interactions, suggesting appropriate screenings, flagging abnormal lab values, and recommending evidence-based order sets.
4 / 15
An 'order set' in an EHR is:
Order sets standardise care for common conditions — a sepsis order set might include blood cultures, antibiotics, IV fluids, and vital sign monitoring, ensuring nothing is missed.
5 / 15
In healthcare IT, 'interoperability' means:
Healthcare interoperability allows different systems (hospitals, labs, pharmacies, payers) to exchange and understand clinical data — the goal FHIR, SMART, and the 21st Century Cures Act pursue.

Sarah from the billing team just posted this Slack message: 'Just flagged a discrepancy on Patient 42B – the system's reporting an incorrect ICD-10 code for their pneumonia diagnosis. It's showing J18.9 instead of J18.91. Can someone investigate?' What does 'ICD-10' likely refer to in this context?
ICD-10 is a globally recognized standard classification system used in healthcare to code diagnoses and procedures. The discrepancy flagged by Sarah indicates an issue with the accurate assignment of these codes within the EHR. Understanding this terminology is crucial for diagnosing and resolving billing errors.

You're reviewing a pull request that adds a new clinical decision support rule to the EHR's patient monitoring system. The PR description reads: 'This rule triggers an alert when a patient's blood pressure exceeds 180/100 mmHg for more than five minutes, prompting immediate notification to the care team.' What is the primary purpose of this 'rule'?
Clinical Decision Support (CDS) rules are designed to assist healthcare professionals by proactively identifying and flagging potentially problematic situations based on predefined criteria. In this case, the rule's goal is to alert clinicians to a critical patient condition – elevated blood pressure – allowing for timely intervention. CDS isn't simply data storage or translation.

David, the EHR implementation specialist, is explaining the concept of 'data normalization' during a standup meeting. He says: 'We need to ensure all patient data – lab results, medication lists, allergies – are stored in a consistent format across the system.' What does 'data normalization' primarily achieve within an EHR?
Data normalization is a crucial process in database design that aims to reduce redundancy and improve data integrity. By enforcing standard data types (e.g., dates, numbers) and relationships between different data elements – like lab results linked to the correct patient – the EHR can maintain consistent and reliable information. This avoids inconsistencies and facilitates accurate reporting.

An API response from the EHR system related to a medication order shows the following JSON snippet: {
"medication_id": "RX123",
"dosage": "50mg",
"route": "oral",
"frequency": "twice daily"
}. What does 'route' most likely represent in this API response?
The 'route' field in an EHR API response specifies how the medication is administered to the patient – whether it's taken orally, intravenously, topically, or by another method. This information is vital for accurate dosage calculations and ensuring proper medication delivery. It's distinct from insurance details or manufacturer information.

During a code review discussion about an EHR module handling patient allergies, Maria asks: 'Are we using a standard terminology like SNOMED CT to represent these allergies?' What is the significance of referencing 'SNOMED CT'?
SNOMED CT (Systematized Nomenclature of Medicine - Clinical Terms) is a globally recognized, comprehensive healthcare terminology that provides a standardized way to represent clinical concepts like allergies. Using SNOMED CT ensures consistent data interpretation and exchange across different EHR systems and healthcare organizations – crucial for accurate patient care.
