1. Hospital statistics

2. Inpatient:
Is a patient who has been formally admitted to the hospital and to whom room, bed and continuous nursing services is provided in an area of the hospital where patients generally stay at least overnight.

3. 1- Inpatient census:
Indicates the number of inpatients presented in the hospital at any given time.
2- Bed count days:
is a unit of measurement denoting the presence of inpatient bed (either occupied or vacant) set up and staffed for use in a one-24-hr period.

4. 3- Total bed count days:
Is the sum of inpatients bed count days in the period under consideration.
Example:
Suppose:
1- The total number of beds available at a certain hospital is 50 beds.
2- Month of Shawwal = 30 days

5. The number of total beds available during month of Shawwal is:
50 x 30 = 1500 bed counts.

6. 4 - Discharges:
Is a termination of hospitalization, whether alive or dead. Deaths are considered discharges and they are included in the total discharges.
A fetus that was not alive at the time of delivery was never a patient and is not included in inpatient hospital statistic.

7. 5- Length of stay:
Number of calendar days from admission to discharge. To compute a patient's length of stay from admission to discharge the date of admission is subtracted from the date of discharge.

8. For example:
1- if a patient was admitted on Safar 25th and discharged Safar 28, his length of stay is (28 – 25) = 3 days.
2- If a patient is admitted and discharged on the same day, his length of stay is one day.

9. Example1:
The following data were obtained from the records of KKU hospital in 1420 (Safar month = 30 days); usually is calculated for one year:

10. 1- Total number of inpatients
= 1869
2- Total number discharged
= 1691
3- Length of stay = 12785
4 – Total number of beds = 500

11. Average daily inpatient census:
Calculate:
Average daily inpatient census:
is the average number of inpatients present each day for a given period of time.
= 1869/ 30 = 62 patients
Total number of inpatients in month of Safar
Total number of days in Safar

12. = 1691/30 = 56 patients 2-Average daily discharged census:
Total number discharged
number of days in Safar

13. = = 12785/ 1691 = 8 days 3- Average length of stay
Total length of stay during Safar
Total discharged during Safar

14. = = 1691/ 500 = 3 Bed turnover rate: Total number of beds
The number of times a bed, on average, change occupants during a given period of time. =
= 1691/ 500 = 3
A bed changed 3 occupants, on average, during Safar
Total number of discharge in Safar
Total number of beds

15. = 5- Bed turnover interval:
period where a bed is unoccupied between patients. =
= ((500) x (30) – 12785)/1691 ) = 1.3
The interval between one occupant and the next is 1 day.
(number of beds) x (number of days in Safar) – length of stay
Number of discharged patients during the month

16. 6- Bed occupancy rate:
proportion of beds occupied during the period of interest. =
= (12785) / (500) x (30) = 85.23%
Total length of stay during Safar
(Total number of beds) x (# of days in the month)
