QUESTIONS WITH FULL SOLUTION GRADED
A+.
◍ 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 Answer: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 Answer:Time-Series
◍ 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
◍ 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
◍ 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?
, Time-series
Clinical trial
Pretest-posttest
Cross-sectional Answer:Cross-sectional
◍ 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?
Case study
Cohort study
Meta-analysis
Literature review Answer:Meta-analysis
◍ 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
