Complete Questions and Guide Answers
100% Verified Graded A+
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?
Time-Series Cross-
Sectional Pretest-
posttest
Randomized Control Trial
Answer: Time-series
,2. A hospital researcher has access to one year of hospital emergency depart- ment
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?
Time-Series Cross-
Sectional Pretest-
posttest
Randomized Control Trial
Answer: Cross Sectional
3. A policy analyst is interested in determining if the prospective payment sys- tem
(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 vari- ables. The analyst hypothesizes
that hospital efficiency should have increased each year after the PPS was
implemented.Which research method should the analyst use?
,Time-Series
Cross-Sectional
Pretest-posttest
Randomized Control Trial
Answer: Time-Series
4. Which type of data analysis could be used in quantitative research?
Reporting the gender of participants
Ranking the severity order with 1 as the worst and 4 as the best Reporting the
distribution of results or outcomes
Using categorical variables with 0=no and 1=yes
Answer: Reporting the distribution of results or outcomes
5. What is a characteristic of qualitative research methods?
Utilizes large sample sizes
Determines causal relationships Generalizes
results to the population
Introduces subjectivity to data collection
Answer: Introduces subjectivity to data collection
, 6. Many physician practices now utilize an electronic health record (EHR) system that
includes a secure messaging feature. Some of these practices have extend- ed their
contact with patients by conducting virtual visits between people with diabetes and
nurses who are certified diabetes educators. The remote tech- nology includes the
ability to monitor blood glucose data to determine if these values are within goal
range. After six months, the results of the blood glucose levels for the group
participating in the virtual visits were evaluated.Which research method was used?
Time-series
Clinical trial
Pretest-posttest
Cross-sectional
Answer: Cross-sectional
7. A researcher wants to determine whether continuity of care is improved with the use
of coordination of care documents among primary care physicians and specialists. The
researcher decides to review various published studies to as- sess the clinical
effectiveness of these documents on patient outcomes.Which research method is
being used?
