EHR Data Analytics & Population Health 5

Question 1

Which term describes the use of EHR data to identify geographic clusters of patients with unusually high disease rates?

Accepted Answer

Spatial epidemiology

Answer

Spatial epidemiology maps disease occurrence geographically to detect clusters and identify environmental or social contributors to health disparities.

Question 2

In EHR analytics, 'data latency' refers to:

Accepted Answer

The delay between data generation and its availability for analysis

Answer

Data latency is the lag between when clinical events occur or are documented and when that data becomes queryable in analytics systems.

Question 3

A value-based care organization tracks the 'cost per member per month' (PMPM). What does this metric primarily measure?

Accepted Answer

Average total healthcare expenditure per enrolled member each month

Answer

PMPM divides total healthcare costs by the number of enrolled members per month, providing a standardized measure of population-level spending.

Question 4

Which method is used in population health to evaluate whether two patient groups are comparable when randomization is not possible?

Accepted Answer

Propensity score matching

Answer

Propensity score matching uses predicted probability of group assignment to create comparable groups in observational studies, reducing selection bias.

Question 5

Which data governance practice ensures that the same clinical concept—such as 'blood pressure'—is defined and measured consistently across all EHR analytics reports?

Accepted Answer

Common data model (CDM) adoption

Answer

Common data models like OMOP or PCORnet standardize how clinical concepts are defined and stored, ensuring consistent measurement across studies and reports.
