HAC Healthcare Analytics Predictive Analytics & Trends 5

Question 1

A predictive model assigns a 73% probability of 30-day readmission to a patient. This output is best described as a:

Accepted Answer

Calibrated probability score

Answer

A calibrated probability score outputs the likelihood of an event, allowing risk stratification rather than just a yes/no prediction.

Question 2

Which approach is used in healthcare predictive analytics to address severe class imbalance, such as when only 2% of patients experience the outcome of interest?

Accepted Answer

SMOTE (Synthetic Minority Over-sampling Technique)

Answer

SMOTE generates synthetic examples of the minority class to balance the training dataset, improving model sensitivity to rare but important outcomes.

Question 3

A health analytics team wants to segment patients into distinct risk groups without a predefined outcome label. Which technique is most appropriate?

Accepted Answer

K-means clustering

Answer

K-means clustering is an unsupervised technique that groups patients based on feature similarity without requiring predefined outcome labels.

Question 4

The Optum, IBM MarketScan, and CMS claims databases are commonly used in healthcare predictive analytics primarily because they:

Accepted Answer

Offer large-scale longitudinal patient data across diverse populations

Answer

These claims databases contain longitudinal records for millions of patients across diverse settings, making them valuable for training and validating population-level predictive models.

Question 5

Which regulatory consideration is most relevant when deploying an AI-based predictive model as a clinical decision support tool in a US hospital?

Accepted Answer

FDA Software as a Medical Device (SaMD) oversight

Answer

The FDA's SaMD framework regulates AI/ML-based clinical decision support tools that meet the definition of a medical device, requiring appropriate clearance or approval.
