  1. Which framework guides the systematic collection, analysis, and use of data for public health program monitoring and improvement?

    Answer: CDC Evaluation Framework

    The CDC Framework for Program Evaluation in Public Health provides a systematic approach to planning, implementing, and using evaluation findings to improve public health programs.

  2. A health informatics specialist calculates that a new EMR system flagged 200 patients for a drug interaction, but only 40 actually had the interaction. What is the positive predictive value (PPV)?

    Answer: 20%

    PPV = True Positives / (True Positives + False Positives) = 40 / 200 = 20%, meaning only 20% of flagged patients truly had the drug interaction.

  3. Which measure is used to compare disease rates between two populations after adjusting for differences in age distribution?

    Answer: Age-Adjusted (Standardized) Rate

    Age-adjusted (age-standardized) rates remove the effect of different age distributions between populations, enabling valid comparisons of disease burden.

  4. Which type of chart is best suited for displaying the frequency distribution of a continuous variable such as age at disease onset?

    Answer: Histogram

    Histograms display the frequency distribution of continuous data by dividing the range into intervals (bins) and showing how observations are distributed across them.

  5. A public health administrator wants to assess whether a new diabetes prevention program reduced hospitalizations. Which study design provides the strongest evidence for causality?

    Answer: Randomized controlled trial (RCT)

    A randomized controlled trial provides the strongest evidence for causality by randomly assigning participants to intervention and control groups, minimizing confounding bias.

  6. Which federal initiative established meaningful use criteria to incentivize healthcare providers to adopt and use certified electronic health record (EHR) technology?

    Answer: HITECH Act

    The HITECH Act (Health Information Technology for Economic and Clinical Health Act), enacted in 2009, established the Meaningful Use incentive program to promote EHR adoption and interoperability.
