RHIT - Registered Health Information Technician Health Information Systems Questions and Answers — Questions and Answers
Question 1: An EHR system automatically generates an alert for a physician who attempts to prescribe a medication to which the patient has a documented allergy. This functionality is a primary example of which type of health information system component?
- Clinical Decision Support (CDS) (Correct answer)
- Master Patient Index (MPI)
- Revenue Cycle Management (RCM)
- Picture Archiving and Communication System (PACS)
Correct answer: Clinical Decision Support (CDS)
Clinical Decision Support (CDS) systems provide real-time, evidence-based information to clinicians at the point of care. An allergy alert is a classic example, as it uses patient data (allergies) to inform a clinical decision (prescribing), thereby preventing a potential adverse event.
Question 2: A primary care clinic needs to send a patient's summary of care record to a specialist at a different facility that uses a separate EHR system. To ensure the receiving system can process and interpret the data correctly, which standard is most commonly used for structuring this clinical document exchange?
- DICOM
- Consolidated-Clinical Document Architecture (C-CDA) (Correct answer)
- ANSI X12
- NCPDP Script
Correct answer: Consolidated-Clinical Document Architecture (C-CDA)
The Consolidated-Clinical Document Architecture (C-CDA) is an HL7 standard that provides a library of templates for clinical documents like summary of care records. It is the required standard under federal programs for creating and exchanging such documents to ensure interoperability between different certified EHR systems.
Question 3: A hospital is preparing for a new EHR go-live. The implementation team decides to activate the new system in the emergency department first, followed by the inpatient units one month later, and outpatient clinics the month after that. This go-live strategy is known as:
- Big bang conversion
- Parallel conversion
- Phased conversion (Correct answer)
- Pilot conversion
Correct answer: Phased conversion
A phased conversion is an implementation strategy where the new system is introduced in stages, either by module, department, or location. This approach allows the organization to manage the change more gradually and apply lessons learned from earlier stages to subsequent rollouts.
Question 4: To ensure that data elements such as 'Patient Gender' and 'State of Residence' are captured consistently across all applications within a healthcare enterprise, a health system should develop and maintain a comprehensive:
- System log
- Interface engine
- Data warehouse
- Data dictionary (Correct answer)
Correct answer: Data dictionary
A data dictionary is a centralized repository of information about data, such as its meaning, relationships to other data, origin, usage, and format. It establishes standard definitions and acceptable values for data elements to enforce consistency in data collection and use across an organization.
Question 5: A radiologist needs to view a patient's CT scan images, which are integrated into the EHR. The specialized information system that acquires, stores, retrieves, and displays these medical images is known as a:
- Picture Archiving and Communication System (PACS) (Correct answer)
- Laboratory Information System (LIS)
- Computerized Provider Order Entry (CPOE)
- Radiology Information System (RIS)
Correct answer: Picture Archiving and Communication System (PACS)
A Picture Archiving and Communication System (PACS) is a medical imaging technology used for storing, retrieving, presenting, and sharing images produced by various medical imaging modalities, such as CT scans, MRIs, and X-rays. It is a core system for radiology and is often integrated with the EHR and RIS.
Question 6: A provider at an urgent care center needs to access the records of a new patient who is visiting from out of state. The provider uses the regional Health Information Exchange (HIE) to search for and retrieve the patient's recent lab results and medication history from their primary care physician. This HIE model is best described as:
- Directed exchange
- Consumer-mediated exchange
- Hybrid exchange
- Query-based exchange (Correct answer)
Correct answer: Query-based exchange
Query-based exchange allows providers to find or 'pull' information on a patient from other providers. This model is particularly useful for unplanned care, such as an urgent care or emergency department visit, where a provider needs to access a patient's history to make timely and informed treatment decisions.
