Mixed Deck — All AHIC Topics Flashcards

Which terminology system is primarily used for inpatient diagnosis and procedure coding for billing and reimbursement in the United States?

Answer: ICD-10-CM/PCS

ICD-10-CM (diagnosis) and ICD-10-PCS (inpatient procedures) are mandated by CMS for hospital billing and reimbursement in the United States.

Which evaluation framework assesses CDS systems across the dimensions of structure, process, and outcomes?

Answer: Donabedian model

The Donabedian model evaluates healthcare quality using structure (resources), process (care delivery), and outcomes (patient results), applicable to CDS evaluation.

A project manager calculates a Cost Performance Index (CPI) of 0.85 for an EHR go-live project. This means the project is:

Answer: Over budget

A CPI below 1.0 indicates the project is spending more than planned for the work completed.

In Agile health IT project management, a 'sprint retrospective' is conducted to:

Answer: Reflect on team processes and identify improvements

The sprint retrospective focuses internally on the team's process, collaboration, and ways to improve future sprints.

A hospital's legacy system uses a proprietary data format. To integrate it with a new EHR, a middleware component is used to translate data formats. What is this component called?

Answer: Interface engine

An interface engine (or integration engine) translates and routes messages between systems using different formats and protocols.

What is the correct order for donning PPE?

Answer: Gown, mask, eye protection, gloves

The correct donning sequence is gown first, then mask/respirator, eye protection/face shield, and gloves last. This prevents contamination during application.

Which HL7 FHIR resource type is used to represent a patient's allergy or intolerance in an interoperable clinical system?

Answer: AllergyIntolerance

The FHIR AllergyIntolerance resource specifically represents patient allergy and intolerance data in a standardized, interoperable format.

Which federal initiative established the foundation for patient access to their own electronic health data in the US?

Answer: The Blue Button Initiative

The Blue Button Initiative, launched by the VA and adopted broadly, enables patients to download and share their own health records electronically.

Which component of the 'Five Rights of CDS' ensures the recommendation is delivered via the most useful format (e.g., alert vs. order set vs. documentation template)?

Answer: Right channel

The 'Right channel' right ensures CDS is delivered through the format most effective for the context, such as an alert, order set, or reference link.

What is the purpose of data mining in healthcare?

Answer: To extract useful patterns and insights from large datasets

Data mining in healthcare involves applying sophisticated analytical techniques to large datasets to discover hidden patterns, correlations, and insights. The purpose is to extract valuable knowledge that can be used for various applications, such as predicting disease outbreaks, identifying at-risk patients, optimizing treatment protocols, and improving operational efficiency. This process helps transform raw data into actionable intelligence.

What is the primary purpose of a Master Patient Index (MPI) in a healthcare information system?

Answer: To uniquely identify and link patient records across systems

An MPI maintains a unique identifier for each patient to prevent duplicate records and link data across disparate systems.

Which of the following describes 'data integrity' in the context of healthcare information security?

Answer: Ensuring that data is not altered or destroyed in an unauthorized manner

Data integrity means protecting information from unauthorized modification or destruction, ensuring accuracy and completeness of health records.

A CDS system uses a patient's estimated GFR to automatically reduce a metformin dose recommendation. This is best classified as which type of CDS?

Answer: Dosing support with patient-specific parameter adjustment

Adjusting a medication dose recommendation based on a patient-specific clinical parameter (eGFR) is a form of patient-specific dosing support.

What does 'uptime' refer to in the context of healthcare information system availability metrics?

Answer: The percentage of time a system is operational and accessible

Uptime measures the proportion of time a system is available and functioning, often expressed as a percentage (e.g., 99.9%).

A clinical informaticist is asked to evaluate a new AI-based CDS tool for predicting 30-day readmission. Which validation step is MOST critical before clinical deployment?

Answer: Prospectively validate the model's performance on the local patient population

Prospective local validation confirms the model's predictive performance holds in the specific patient population and care environment where it will be deployed.

What is the function of an Application Programming Interface (API) in health information systems?

Answer: To define rules for how software components communicate and share data

APIs specify how different software components interact, enabling controlled data sharing between systems like EHRs and third-party apps.

Which NQF concept ensures that a quality measure is worth the cost and burden of measurement by evaluating if the measure addresses an important gap in care?

Answer: Importance to measure and report

The NQF's 'Importance to measure and report' criterion evaluates whether a measure addresses a significant opportunity for improvement and whether the measure would meaningfully affect patient care and outcomes.

A hospital's IT governance board must decide between two EHR upgrade proposals. The BEST governance practice is to evaluate proposals based on which primary criteria?

Answer: Alignment with strategic goals, cost-benefit analysis, and risk assessment

Sound IT governance requires evaluating proposals against strategic alignment, return on investment, and risk to make objective, organization-wide decisions.

In health informatics project management, a 'work package' is BEST described as:

Answer: The lowest-level component of a work breakdown structure

Work packages are the smallest units of the WBS where work can be assigned, scheduled, costed, and monitored.

In evidence-based CDS, what is the role of a clinical knowledge management system?

Answer: To maintain, version, and govern the rules and evidence that drive CDS recommendations

A clinical knowledge management system centralizes governance of CDS content, tracking versions, evidence sources, and approval workflows.
