1. Which research design examines data collected at equally spaced points in
time to identify trends?
A. Cross-sectional
B. Time-series
C. Case study
D. Cohort
Correct Answer: B. Time-series
2. 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?
a) t-test
b) Analysis of variance
c) Regression analysis
d) Pearson product-moment correlation coefficient - ANSWER Regression
analysis
,3. 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?
a) Mann-Whitney U test
b) Bayesian approach
c) Regression analysis
d) Wilcoxon signed-rank test - ANSWER Regression analysis
4. What type of database contains anonymous data with no identifying
information?
A. Relational database
B. De-identified database
C. Transactional database
D. Object-oriented database
Correct Answer: B. De-identified database
5. Which database type is best suited for managing complex, interrelated data
structures?
A. Flat-file database
B. Relational database
C. Object-oriented database
D. Data warehouse
Correct Answer: C. Object-oriented database
,6. 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?
a) Analysis plan
b) Data collection
c) Study population
d) Research design - ANSWER Research design
7. 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?
a) Analysis plan
b) Data collection
c) Study population
, d) Research design - ANSWER Analysis plan
8. 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?
a) HCAHPS scores
b) Staff turnover rates
c) HIPAA violation lists
d) Prescription data - ANSWER HCAHPS scores
9. 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
a) Patient wait times
b) Patient portal usage
c) Patient satisfaction surveys
d) Patient demographic profiles - ANSWER Patient wait times
Patient satisfaction surveys
10.A hospital is experiencing a high rate of nursing turnover during the first
year at the hospital. There are many theories as to why turnover in this
