A hospital would like to reduce the outstanding accounts
receivables with large amounts. The chief financial officer (CFO)
asked the director of patient accounts to identify delinquent
accounts based on patient demographics to create a collection
process through the patient portal. How should the CFO use the

To outsource the hospital's collection function
To implement improvements in the revenue cycle process
To explain delays in collection to the board's finance committee
To replace staff in areas where substandard performance is
identified - ✔✔✔ Correct Answer > To implement improvements in the
revenue cycle process
A researcher wants to determine whether continuity of care is
improved with the use of coordination of care documents among
primary care physicians and specialists. The researcher decides
to review various published studies to assess the clinical
effectiveness of these documents on patient outcomes.Which
research method is being used?

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?

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

A policy analyst is interested in determining if the prospective
payment system (PPS) has improved hospital efficiency over time
during the past ten years. The sample for analysis consists of ten
years of data after the introduction of the PPS and includes
measures of efficiency and other relevant control variables. The
analyst hypothesizes that hospital efficiency should have
increased each year after the PPS was implemented.Which
research method should the analyst use?

The quality improvement team is reviewing quarterly incident
reports and evaluating the effect of Six Sigma strategies on the
quantity of medication errors over the past two years. The team
hypothesizes a continuous reduction in medical errors for each
quarter. The sample consists of patient clinical and demographic
characteristics. Unfortunately, causation cannot be determined
from the data available. Which research method should be used
to test the team's hypothesis?
