SECTION 1: RESEARCH METHODS & STUDY DESIGNS

Question 1

The quality improvement team is reviewing quarterly incident
reports and evaluating the effect of Six Sigma strategies on
the quantity of medication errors over the past two years. The
team hypothesizes a continuous reduction in medical errors
for each quarter. The sample consists of patient clinical and
demographic characteristics. Unfortunately, causation cannot
be determined from the data available. Which research
method should be used to test the team's hypothesis?

 A) Cross-sectional
 B) Case-control
 C) Time-series
 D) Experimental design

✅ Correct Answer: C) Time-series

, Rationale: Time-series analysis examines data points collected at
specific time intervals. This method is appropriate for analyzing
trends over time, such as quarterly medication error rates
following a Six Sigma intervention, and can identify patterns over
the observation period. However, it cannot establish
causation because other confounding factors may influence
observed trends.




Question 2

A hospital researcher has access to one year of hospital
emergency department claims data. The researcher is
investigating the association of race on the timeliness of
delivery of care. The sample includes information on patient
demographics, insurance information, and emergency
department factors. Due to patient confidentiality, the sample
does not include patient clinical information and outcomes.
Which research method should be used?

 A) Longitudinal study
 B) Cross-sectional
 C) Experimental design
 D) Meta-analysis

✅ Correct Answer: B) Cross-sectional

Rationale: Cross-sectional studies analyze data from a population
at a specific point in time. This method is appropriate when
examining associations between variables (such as race and

, timeliness of care) using existing data without following subjects
over time. It is ideal for analyzing claims data from a defined one-
year period.




Question 3

A policy analyst is interested in determining if the prospective
payment system (PPS) has improved hospital efficiency over
time during the past ten years. The sample consists of ten
years of data after PPS introduction and includes measures of
efficiency and other relevant control variables. The analyst
hypothesizes that hospital efficiency should have increased
each year after PPS implementation. Which research method
should be used?

 A) Case study
 B) Randomized control trial
 C) Time-series
 D) Cross-sectional

✅ Correct Answer: C) Time-series

Rationale: Time-series analysis is ideal for evaluating changes
over time, particularly when examining whether a policy
implementation (PPS) led to progressive improvements in
efficiency measures across multiple years.

, Question 4

A large teaching hospital is preparing to implement a hand
hygiene protocol to reduce infection rates. The research team
will evaluate best practices and outcomes from other
facilities. What is the appropriate research method to prepare
for the new protocol?

 A) Focus group
 B) Delphi technique
 C) Literature review
 D) Observational study

✅ Correct Answer: C) Literature review

Rationale: A literature review systematically examines existing
published research to identify best practices, evidence-based
interventions, and outcomes from other facilities. This is the
appropriate first step when preparing to implement a new clinical
protocol.




Question 5

A facilitator meets with several healthcare staff members to
get feedback and input about how the staff thinks the goal of
increasing hand washing through observation methods has
worked. Which research method is being used by the
facilitator?

 A) Survey
