✔✔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 - ✔✔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 - ✔✔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?

✔✔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?

Prescription data - ✔✔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

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

✔✔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 cohort is so high. The chief
executive officer (CEO) has asked the nursing director to study this further and develop
some tactics to improve nursing retention. The director plans to gather data, conduct
some statistical analysis, and report back to the CEO with an improvement plan.Which
type of data would the director gather to develop this plan?

Hospital tenure for nurses
Overall hospital turnover rate
Frequency of hire dates for nurses - ✔✔Hospital tenure for nurses
✔✔A large urban hospital has implemented a new patient registration system to reduce
patient complaints, streamline the process, and make it easier to understand.The
hospital had been monitoring patient wait times for registration prior to implementing this
change.Which aspect of wait time was analyzed in the application of descriptive
statistics applied for this scenario?
, A p-value of wait times was analyzed.
An ANOVA of wait times was analyzed.
An average of wait times was analyzed.
A chi-square of wait times was analyzed. - ✔✔An average of wait times was analyzed.
✔✔A surgical center is experiencing patient attrition. The center has received bad
reviews online. One area of complaints is that the center is dirty in common areas. The
center conducted a survey to ascertain what the major complaints were. The center has
decided to outsource its maintenance in an effort to improve patient satisfaction scores.
The median patient satisfaction scores were determined from the survey. How were
descriptive statistics applied in this scenario?
To determine the variance in patient satisfaction scores
To determine factors that influence patient satisfaction scores
To determine the 50th percentile of patient satisfaction scores
To determine the minimum and maximum patient satisfaction scores - ✔✔To determine
the 50th percentile of patient satisfaction scores
✔✔An administrator at an established hospital decided to create a new data collection
plan for the quality improvement initiative because the former plan was not
acceptable.One concern with the old plan was with the timeliness of the data and with
missing data elements associated with wait times and communication.How were
descriptive statistics applied in this scenario?
To confirm overall diagnoses across timeTo identify the average patient satisfaction
scoreTo create a baseline in the organization's current performanceTo run a regression
to ensure patients are eligible for bonus programs - ✔✔To identify the average patient
satisfaction score
