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
Analysis of variance
Regression analysis
Pearson product-moment correlation coefficient - 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?
Mann-Whitney U test
Bayesian approach
Regression analysis
Wilcoxon signed-rank test - 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 MethodsA 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?
Analysis plan
Data collection
Study population
Research design - ANSWER- Research design
Assoc. between pt satisfaction & hospital market share. Researcher
hypothesizes that increased pt satisfaction will lead to increase in hosp.
market share. Longitudinal study of 7 years will be conducted to assess
the change in hospital market share over time. Urban hospitals from the
U.S. that have > 100 beds will be included. The data set will include
hosp. characteristics and market characteristics. Admin. data will be
obtained from the Am. Hospital Association's Annual Survey of
Hospitals, the Area Health Resources File, and the Hosp. Compare
website. The variables included in the data set will control for other
factors that may impact hospital pt satisfaction. Stat. significance will be
set at α = 0.05 for the analysis. The results of the analysis will be of

interest to hospital administrators and policy makers. Which component
is missing? Analysis plan Data collection Study population Research
design - ANSWER- Analysis plan
After reviewing a quality report from a large urban hospital, an
administrator decided to implement a new initiative to improve
communication among healthcare professionals. The hospital
administrator conducted a survey on safety and error prevention that
revealed that ineffective or insufficient communication among team
members is a significant contributing factor to adverse events.Which
source of data would have been used to highlight patient perception of
care?
HCAHPS scores
Staff turnover rates
HIPAA violation lists
Prescription data - ANSWER- HCAHPS scores
There have been recent complaints at a pharmacy regarding care, wait
times, and errors. The administrator wants to further examine customer
satisfaction rates. After examining more information the administrator
decides to develop a new patient portal that will allow patients to
perform a refill request online. The system will also allow patients to
request refills via text or mobile devices.Which two sources of data were
used in the change from the old system to the new system? 2 answers
Patient wait times
Patient portal usage
Patient satisfaction surveys
