The state public health researcher wants to begin a five-year initiative to
coordinate immunizations for children in the foster care system. The results will be
compared to previous years to measure the effectiveness of the initiative.Which
research method should be used to study this initiative?
Case study
Cohort study
Longitudinal study

Pre/post-study
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?
Time-Series
Cross-Sectional

Pretest-posttest
Randomized Control Trial
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?
Time-Series
Cross-Sectional
Pretest-posttest
Randomized Control Trial

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 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?

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 assess

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
Time-series
Using publicly reported data from Centers for Medicare & Medicaid Services,
researchers want to examine the relationship between 30-day readmissions and
mortality rates for patients with heart failure at five facilities. Before this can be
done, researchers need to estimate mortality rates and readmission rates from
heart failure.Which statistical technique should be used to calculate the estimated
rates?
T-test
