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
<Ans> Time-Series
2. A hospital researcher has access to one year of hospital emergency de-
partment 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?-
: Cross-Sectional
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 for analysis consists of ten years of data after the
introduction of the PPS and includes measures of efficiency and other relevant contro
variables. The analyst hypothesizes that hospital efficiency should have increased
each year after the PPS was implemented.: Time-Series

, 4. Which type of data analysis could be used in quantitative research <Ans>
Report- ing the distribution of results or outcomes
5. What is a characteristic of qualitative research methods <Ans> Introduces
subjec- tivity 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 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
<Ans> 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 assess
the clinical effectiveness of these documents on patient outcomes. Which research
method is being used <Ans> Meta-analysis
8. The state public health researcher wants to begin a five-year initiative to co-
ordinate immunizations for children in the foster care system. The results will
