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
ANSWERS: 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
ANSWERS: 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
ANSWERS: 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
ANSWERS: 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
ANSWERS: HCAHPS scores
