What does the term 'data governance' refer to in a clinical analytics context?
Answer: Policies and standards ensuring data quality, security, and appropriate use
Data governance encompasses the policies, roles, and standards that ensure data is accurate, secure, consistent, and used appropriately across an organization.
A clinical informatics team is comparing outcomes between patients who received a new care protocol versus those who did not using existing EHR data. This study design is best described as:
Answer: Retrospective cohort study
A retrospective cohort study uses existing data to follow groups with different exposures over time to compare outcomes, without prospective randomization.
In population health analytics, which approach uses claims data to identify patients with gaps in preventive care?
Answer: Measure-based care gap analysis
Care gap analysis uses claims or clinical data to identify patients who are due for or have missed recommended preventive services based on quality measures.
Which interoperability standard is specifically designed to enable clinicians and patients to access and exchange health data through APIs?
Answer: HL7 FHIR
HL7 FHIR (Fast Healthcare Interoperability Resources) uses RESTful APIs and modern web standards to enable flexible, real-time health data exchange.
A population health dashboard shows a hospital's 30-day readmission rate is 15% compared to the national benchmark of 12%. What is the most appropriate next step?
Answer: Drill down into readmission data by diagnosis and demographic subgroups
Stratified analysis by diagnosis and demographics identifies specific patient populations or conditions driving excess readmissions, enabling targeted interventions.
Which concept describes the degree to which a clinical data element consistently measures what it is intended to measure across different settings and times?
Answer: Data reliability
Data reliability (also called consistency) refers to the reproducibility and stability of a data element across different contexts, abstractors, or time points.
The Triple Aim framework in population health focuses on improving three dimensions simultaneously. Which combination is correct?
Answer: Patient experience, population health, and per capita cost
The IHI Triple Aim targets improving patient experience of care, improving population health, and reducing per capita cost of healthcare.
