OCCUPANCY RATES and MORTATLITY RATES
Percentage of Occupancy
• Provides a hospital with a ratio or percentage of the equipped and staffed hospital beds that are occupied for a specified period of time
Bed Count
• The number of available hospital inpatient beds, both occupies and vacant, on any given day
• Excluded beds: temporary beds (for examination), disaster beds, ER beds
• A hospital is licensed for a certain number of beds
• Adding/decreasing: Beds, or units, can be “closed” and re-opened as necessary
• So bed count can change
Bassinet Count
• The number of available hospital newborn bassinets, both occupied and vacant, on a given day
Rate Formula
• General Rule
The number of times something happens The number of times it could happen
Inpatient Bed Occupancy Rate
• The proportion of inpatient beds occupied as compared to how many could have been occupied
Daily IP censusInpatient bed count for that day X 100
Example
• On July 1, the bed count was 200. The IPSD total for the day was 160
160/200 x 100 = 80% Occupancy rate
Temporary beds
• If there is full occupancy plus disaster beds need to be used, the occupancy rate can actually be MORE than 100%
• The temporary beds are NOT added to the bed count but the patients occupying them ARE added to the census
Bassinet Occupancy Rate
Daily NB censusNB bassinet count for that day x 100
MORTALITY RATES
• Mortality = Death
• A patient who dies at home or en route to the hospital or during an outpatient procedure is not included in inpatient mortality rates
• Newborns ARE included in this rate
Death as Discharge
• A death is considered a discharge but is reported separately than live discharges
Newborn Death
• Only counted in those infants who have shown signs of life at the time of birth
• Included in hospital death rates, but the hospital may also want to calculate them separately
• If there was no sign of life, counted as a fetal death and not included in death rate
Death Rates
• Based on discharge data, a list is prepared of all patients who died during their hospital stay
• Calculating the rate
Total number of deaths for a periodTotal number of discharges for the period x 100
Death Rate
• Should be low
• A “net” death rate may be calculated– Does not include deaths occurring under 48 hours of admission
– Out of date today, because of shorter stays
Surgical Death Rates
• Postoperative death rate
Total surgical deaths Total patients operated on X 100
Surgical Death Rates
• Anesthesia Death Rate
Total deaths caused by anesthetic agentsTotal number of anesthetics administered X 100
Other Rates
• Obstetrical related rates
• Autopsy rates
Length of Stay
• LOS
• The number of calendar days from admission to discharge
• Average LOS: the average hospitalization length of a group of inpatients discharged during a period
Length of Stay
• Each day counts as a day except the day of discharge
• Example: A patient is admitted on June 3 and discharged June 10. LOS is 7 days.
Length of Stay
• A&D: LOS is ONE day regardless of time
• The total LOS for all patients during a specified period is commonly referred to as discharge days
Average LOS
Example: Total discharges in March is 700, total discharge days is 3500 = 5 day average LOS
Total length of stay (discharge days) Total discharges x100
