AHRQ

Agency for Healthcare Research and Quality

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?

Gross autopsy rate

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
