Healthcare Information Systems Flashcards

What is the primary function of a Master Patient Index (MPI) within a healthcare organization's information system?

Answer: To maintain a single, accurate record of every patient by linking their information from various systems.

The Master Patient Index (MPI) serves as the authoritative source for patient identity. Its core purpose is to link a patient's records from different departments and systems (e.g., registration, lab, radiology) to create one comprehensive and accurate master file, preventing dangerous duplicate records.

A Patient Access Representative is registering a patient and the system identifies two possible existing records with slight variations in the date of birth. Merging these records without proper investigation could lead to what critical patient safety risk?

Answer: Fragmented medical history, potentially causing incorrect treatment or medication errors.

Creating or using a duplicate medical record is a major patient safety issue. It fragments the patient's history, meaning a provider may not have access to critical information like allergies, previous diagnoses, or current medications, which can lead to severe adverse outcomes, including medication errors and misdiagnosis.

Which of the following actions is a crucial practice for a Patient Access Representative to protect electronic patient information in compliance with the HIPAA Security Rule?

Answer: Logging out of the system or locking their computer screen every time they leave their desk.

The HIPAA Security Rule requires covered entities to implement technical safeguards to protect electronic Protected Health Information (ePHI). A fundamental practice for all users, including Patient Access Representatives, is to prevent unauthorized access by locking or logging out of their workstation, ensuring that unattended screens do not expose patient data.

During an unexpected system-wide network outage, a Patient Access Representative is unable to access the electronic registration system. What is the MOST appropriate initial action?

Answer: Switch to the facility's documented downtime procedures and use paper-based forms.

Hospitals have established downtime procedures to ensure continuity of care during system outages. The correct response is to immediately revert to these official protocols, which typically involve using paper forms to capture necessary patient information that will be entered into the system once it is restored.

The ability of a hospital's Electronic Health Record (EHR) system to securely send and receive patient data from a completely different system at an external clinic is an example of:

Answer: Interoperability

Interoperability is the term used to describe the ability of different information systems, devices, and applications to access, exchange, integrate, and use electronic health information in a coordinated manner, across organizational boundaries.

To confirm that a scheduled outpatient procedure has been properly ordered by a physician, which element within the healthcare information system should the Patient Access Representative verify?

Answer: A provider's order via Computerized Physician Order Entry (CPOE).

Computerized Physician Order Entry (CPOE) is the system clinicians use to place orders for medications, tests, and procedures electronically. The Patient Access Representative must verify that a valid, signed order exists in the system to ensure the service is medically necessary and authorized before the patient receives care.
