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? - (CORRECT
ANSWER)time series
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? - (CORRECT ANSWER)Cross Sectional
Which type of data analysis could be used in quantitative research? - (CORRECT
ANSWER)Reporting the distribution of results or outcomes
,What is a characteristic of qualitative research methods? - (CORRECT 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? - (CORRECT 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? - (CORRECT ANSWER)Time Series
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? - (CORRECT 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? - (CORRECT
ANSWER)Pre/post-study
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? - (CORRECT
ANSWER)Regression analysis
Researchers want to determine if a particular risk factor or risk factors are associated with the
frequency for nonelective readmission within 30 days among patients with diabetes in a
metropolitan area. The variables of interest include age, gender, race/ethnicity, and insurance
status.
Which statistical technique should be used? - (CORRECT ANSWER)Regression analysis
A hospital researcher is interested in investigating the association between hospital ownership
(i.e., government, investor, and not-for-profit) on overall hospital quality scores.
, Research Methods
A cross-sectional data set of all urban hospitals from eight states is used in this study. The data
were obtained from various administrative databases: Medicare Hospital Cost Report
Information System, the American Hospital Association, and the Area Health Resource File.
Descriptive statistics are used to summarize the data. An ordinary least squares regression is used
to test the relationship between ownership status and hospital quality while controlling for
hospital and market characteristics.
Which component is missing from these research methods? - (CORRECT ANSWER)Research
design
A hospital researcher is interested in the association between patient satisfaction and hospital
market share. The researcher hypothesizes that increased patient satisfaction will lead to an
increase in hospital market share.
Research Methods
A longitudinal study of seven years will be conducted to assess the change in hospital market
share over time. Urban hospitals from the United States that have more than 100 beds will be
included in the analysis. The data set will include hospital characteristics and market
characteristics. Administrative data will be obtained from the American Hospital Association's
Annual Survey of Hospitals, the Area Health Resources File, and the Hospital Compare website.
The variables included in the data set will control for other factors that may impact hospital
patient satisfaction. Statistical significance will be set at α = 0.05 for the analysis. The results of
the analysis will be - (CORRECT ANSWER)Analysis plan
A large urban hospital has implemented a new patient registration system to reduce patient
complaints, streamline the process, and make it easier to understand.
