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

,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?

, 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

outcomes.Which research method is being used?
Case study
Cohort study
Meta-analysis
Literature review
