3. Chapter 4 Census Inpatient census
Number of inpatients present in a health care facility at any one time
Census taking time
Consistent time of day when all inpatient units count and report the number of patients on the unit (usually midnight)
Admission, discharge, transfer are referred to as ADT
IPSD – Inpatient Service Days
DIPC – Average Daily Inpatient Census
Inpatient census taking time is usually midnight (12:00 a.m.)
Data used for planning, budgeting, staff
Previously done manually
Now census is computerized
Number of inpatients present on a patient care unit at census taking time each day
Plus any patients admitted after the previous census-taking time and discharged before the next census-taking time
Unit of measure denoting services received by one inpatient during one 24-hour period
Also referred to as:
Patient day
Inpatient day
Census day
Bed occupancy day
Sum of all the inpatient service days for the period
Period can be days, weeks, months, or years
Included in the total inpatient service day calculations:
Deaths are considered discharges
Exception if the term live discharges is used
Deaths must be added to the live discharges to get the number of inpatient discharges
Not included in the total inpatient service day calculations:
Fetal death
Not alive at the time of delivery
Dead on arrival (DOA)
No signs of live at time brought to the hospital
Outpatient death
Outpatients are not included in inpatient statistics
Counted and maintained separately
School of Health Science 3

4. Chapter 4 Census
Average daily inpatient census (or average daily census)
Average number of inpatients present each day for a given period of time
-Average represents days when both large and a low number of patients are serviced
-Adults, children, and newborn are reported separately
Average daily inpatient census formula includes:
-Total inpatient service days for the period
-Divided by total number of days in the period
-Days in the period (month, semiannual, annual, leap year)
-Calculate adults and children separate from newborn
School of Health Science 4

5. Chapter 4 Census To calculate take census from day prior
Add in Admissions
Subtract Discharges
Add in any transfers in
Subtract any transfers out
A&D on same day? Not included in census calculation, as this is the census number at census taking time
School of Health Science 5

6. Chapter 4 Census
Number of inpatients present on a patient care unit at census taking time each day, plus any patients admitted after the previous census-taking time and discharged before the next census-taking time
IP Deaths are included in discharges – Fetal deaths, DOA’s and OP deaths are not
Census from day prior + admissions – discharges + transfers in – transfers out + patients admitted and discharged on same day = DIPC
Sum of all the inpatient service days for the period
Period can be days, weeks, months, or years
Calculation for a single day is the same as DIPC calculation – typically not looking at a single day though, so you need to look at entire period for which you’re calculating

7. Chapter 4 Census Jan 31: Census 456 Feb 1: Admissions 58 Discharges 45
DOA 3
Calculate:
A) Census for February 1
B) IPSD total for February 1
C) DIPC for February 1
School of Health Science 7

8. Chapter 4 Census #10-(A) Answer – 469 Census on Jan 31 – 456
+ 58 Admissions
- 45 Discharges
= Census
School of Health Science 8

9. Chapter 4 Census #10 (B) Answer – 475 Census on Jan 31 – 456
+ 58 Admissions
- 45 Discharges
+ 6 A&D’s
= 475
School of Health Science 9

10. Chapter 4 Census #10 (B) Answer – 475
DIPC (Daily Inpatient Census) and IPSD (Inpatient Service Day) calculations are the same!

11. Chapter 5 Percent of Occupancy
Bed Count – Number of Available Beds (both occupied and vacant)
Bassinet Count – Number of Newborn Bassinets available (both occupied and vacant)
A&C – Adults and Children
NB – Newborn
Occupancy Ratio – Number of beds occupied/Number of beds available
Bassinet occupancy includes:
Only newborns born in the hospital during that hospital admission
Admitted to the units designated for newborns such as neonatal unit, or intensive care neonatal unit
Does not include babies born en route or admitted after being born elsewhere
Occupancy does not include beds in the:
Emergency department treatment rooms
Operating suite
Observation
23-hour hold
Outpatient procedure department
Inpatient bed count day and inpatient bassinet count day
Unit of measure denoting the presence of one inpatient bed/bassinet
Set up and staffed for use during a 24-hour period
Bed and bassinet may be occupied or vacant
Inpatient bed count days (total)
Sum of inpatient bed count days during the period
Period can be days, months, semiannual, or annual
Disaster beds
Temporary beds not included in the bed count
Occupancy ratio
Percentage of available beds or bassinets being occupied on a specific day or a designated period of time
Day/Month/Year
Proportion of inpatient beds occupied
Ratio of service days to inpatient bed count days for the period
School of Health Science 11

12. Chapter 5 Percent of Occupancy
Total IP Occupancy Percentage
Total IPSD for a period
Total IP bed count x number of days in period
X 100 = Inpatient bed occupancy for period
50 bed hospital with 1410 IP service days for June – what was occupancy percentage?
1410/(50X30) X 100 = 94%
Same applies to NB bassinets or specific unit occupancies – just need to adjust the numerator & denominator to reflect appropriate figures
For long-term planning
Need data for more than one day
Applies to both inpatient and bassinet
Formula:
Total IP service days in a period  100/total bed count days in the period
Bed count  number of days in the period
When a permanent bed count changes for a period the number in the denominator also changes
Total IP service days in a period  100/(Bed count  days) + (bed count  days)

17. Chapter 6 Length of Stay/Discharge Days
Discharge – termination of hospitalization – includes AMA & death
Length of Stay (LOS) – number of calendar days from admission to discharge for a patient
Discharge Days – same as LOS
Length of stay and discharge days
Manage utilization of services
Discharge days
Analyze and compare groups of patients by disease, treatment, age, procedures, provider
Discharge
Termination of hospitalization is written
Death is a discharge
Against medical advice (AMA)
Patient leaves the hospital without a written order or approval to leave
Calculated for each patient upon discharge
Total number of days the patient was hospitalized and received services
Calculate by subtracting the date of admission from the date of discharge
Compiled at the time of discharge or death
LOS
Number of calendar days from admission to discharge for each individual inpatient
Synonymous terms include:
Days of service
Duration of hospitalization
Discharge days (DD)
School of Health Science 17

18. Chapter 6 Length of Stay/Discharge Days
A&D on same day? 1 day LOS
Admitted 1 day, d/c the next? 1 day LOS
Anything longer – count the day of admission and all subsequent days except the day of discharge
Remember your # of days in month – 30 days hath September, April, June & November, all the rest have 31 (except February…)
Count each day of an inpatient stay except the day of discharge
Long length of stays can include many months
Remember number of days in a month to calculate long LOS
School of Health Science 18

19. Chapter 6 Length of Stay/Discharge Days
Admitted on December 1st
Discharged on December 13th
What is LOS??
12 days
Count December 1 – 12, do not count 12/13
School of Health Science 19

20. Chapter 6 Length of Stay/Discharge Days
Sum of the days of stay of all inpatients, or a group of patients
Discharged during a specified period of time such as a date, week, month, or year
Synonymous term
Discharge days
Average Length of Stay (ALOS)
Average length of hospitalization of a group of inpatients discharged during a period of time such as a date, week, month, or year
Most common use of discharge days is in determining the average length of stay
Compute adults and children separate from newborn
Formula for adults and children:
Total LOS (discharge days)/total discharges
Formula for newborn:
Total NB length of stay (discharge days)/total newborn discharges
School of Health Science 20

21. Chapter 6 Length of Stay/Discharge Days
Total Length of Stay (A&C)
Total Discharges
Hospital had total of 700 discharges in March, with 3,500 discharge days, what is Average LOS?
3500/700 = 5 – Average LOS was 5 days
Compute adults and children separate from newborn
Formula for adults and children:
Total LOS (discharge days)/total discharges
Formula for newborn:
Total NB length of stay (discharge days)/total newborn discharges
