What rates would adequately describe the observed number of deaths in a community?
20/100,000 in January 2000
2/1,000 in January 2000
What rate describes the number of new cases of an illness for a specific time period?
Incidence rate
What term is used to describe the number of inpatients present at the
census- taking time each
day plus the number of inpatients who
were both admitted and discharged after the census-taking
time
the previous day?
Daily inpatient census
What unit of measure is used to indicate the services received by one
inpatient in a 24-hour
period?
Inpatient service day
What rate is used to compare the number of inpatient deaths to the
total number of inpatient
deaths and discharges?
Gross hospital death rate
Suppose a patient who underwent orthopedic surgery acquired
Klebsiella pneumonia while
hospitalized. How could this illness
be described?
As a postoperative infection
As a hospital-acquired
infection
As a community acquired infection
What term is used to describe the number of calendar days that a patient is hospitalized?
Length of stay
What rate is used to indicate the percentage of the hospital’s beds
occupied by inpatients for a
given time period?
Total length of stay
Inpatient bed occupancy rate
What rate compares the number of autopsies performed on hospital
inpatients to the total
number of inpatient deaths for the same
period of time?

Suppose that five patients stayed in the hospital for a total of 27
days. Which term would be used
to describe the result of the
calculation 27 ÷ 5?
Average length of stay
The probability of death among diagnosed cases of a specific disease is termed:
case fatality rate
What data elements are considered protected under the HIPAA Privacy Rule?
Patient telephone number
Patient name
Medical record
number
Zip code
FTE
Full-time equivalent employee
Employee compensation
Annual compensation =
hours X per hour X % benefits
Productivity:
Amount of work completed X number or work days per year
(5 workdays per week X 52 weeks per year)
Unit labor costs:
Compensation / productivity
Completed work = total work output – defective work
Labor productivity = completed work / hours worked to produce total work output
(Work output / total hours worked)
Staffing levels:
Patient encounters / productivity = number of FTE’s needed
(Inpatients per day / records coded per day)
FTE’s example:
Minutes X records = total minutes
¯
Total minutes / 60 minutes (hours) = total hours
¯
Total hours / productive hours = FTE’s needed
Operational budget
Budgeted – actual = variance
(Variance x 100) / budgeted = % over or under budget
Capital budget (high dollar assets)
Total cost of project / Annual incremental cash flow
(Annual incremental cash flow refers to the savings that a development realizes from the project)
Return on investment (ROI)
(Average annual incremental cash flow X 100) / Total cost of the project
Case Mix index
(The average relative weight of all cases treated at a given facility or by a given physician. Case mix is always reported with four decimal points)
Sum of the weights of MSDRG’s for patients discharged during a given period / total number of patients discharged
Calculating rates
(Number of time something happened X 100) / number of times something could have happened
Purchase shelves
inches per shelf × shelves per unit = linear filing inches per unit
records × 1 inch per record = inches of records to be filed
(inches of records needed) / inches per unit = filing units
New file folders needed for next year
admissions (year currently) + additional admissions/year = total admissions next year
total admissions X % readmission rate = readmissions next year
total admissions - readmissions = new file folders needed for next year
Budget allocation for storage space
inpatients × inch per record = total inpatient inches
ER patients × inch per record = total ER inches
Inpatient inches + ER inches = total inches of filing space per year
total inches × $ per filing inch = $ budget allocation for storage space
