ORGANIZATIONAL ANALYSIS HANDBOOK
◉ 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
