Answer

Sensitivity measures the proportion of actual positives correctly identified by the test, calculated as TP / (TP + FN).

Question 2

A health system is designing its disaster recovery plan. The Recovery Point Objective (RPO) defines which of the following?

Accepted Answer

The maximum acceptable data loss measured in time

Answer

RPO defines the maximum tolerable period in which data might be lost, determining how frequently backups must occur.

Question 3

A hospital is transitioning from ICD-9-CM to ICD-10-CM for diagnosis coding. Which characteristic of ICD-10-CM represents its MOST significant structural difference?

Accepted Answer

Alphanumeric codes with up to 7 characters providing greater specificity

Answer

ICD-10-CM uses alphanumeric codes up to 7 characters, allowing far greater clinical specificity than ICD-9's numeric 5-digit codes.

Question 4

In health informatics, which type of study design provides the HIGHEST level of evidence for evaluating the effectiveness of a health IT intervention?

Accepted Answer

Randomized Controlled Trial (RCT)

Answer

RCTs provide the strongest evidence by randomly assigning participants to intervention and control groups, minimizing bias.

Question 5

A CMIO is implementing a sepsis early warning algorithm in the EHR. Which ethical concern is MOST critical when deploying predictive algorithms in clinical care?

Accepted Answer

Algorithmic bias leading to disparate outcomes across patient populations
