Question:
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. Time-Series
B. Cross-Sectional
C. Pretest-posttest
D. Randomized Control Trial
✔✔ Correct Answer: A. Time-Series
,Rationale:
A time-series design is appropriate for examining trends in medication
errors over multiple quarters without implying causation.
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. Time-Series
B. Cross-Sectional
C. Pretest-posttest
D. Randomized Control Trial
✔✔ Correct Answer: B. Cross-Sectional
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 for analysis consists of ten years
of data after the introduction of the PPS and includes measures of
efficiency and other relevant control variables. The analyst
hypothesizes that hospital efficiency should have increased each year
after the PPS was implemented. Which research method should the
analyst use?
, A. Time-Series
B. Cross-Sectional
C. Pretest-posttest
D. Randomized Control Trial
✔✔ Correct Answer: A. Time-Series
Which type of data analysis could be used in quantitative research?
A. Reporting the gender of participants
B. Ranking the severity order with 1 as the worst and 4 as the best
C. Reporting the distribution of results or outcomes
D. Using categorical variables with 0 = no and 1 = yes
✔✔ Correct Answer: C. Reporting the distribution of results or
outcomes
What is a characteristic of qualitative research methods?
A. Utilizes large sample sizes
B. Determines causal relationships
C. Generalizes results to the population
D. Introduces subjectivity to data collection
✔✔ Correct Answer: D. Introduces subjectivity to data collection
Many physician practices now utilize an electronic health record (EHR)
system that includes a secure messaging feature. Some of these
practices have extended their contact with patients by conducting
virtual visits between people with diabetes and nurses who are
certified diabetes educators. The remote technology includes the
