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

The number of times something happens 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 census Inpatient 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 census NB 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

Total number of deaths for a period 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 period Total 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Rate Should be low A “net” death rate may be calculated Does not include deaths occurring under 48 hours of admission Out of date today, because of shorter stays

Total patients operated on X 100 Surgical Death Rates Postoperative death rate Total surgical deaths Total patients operated on X 100

Total deaths caused by anesthetic agents Surgical Death Rates Anesthesia Death Rate Total deaths caused by anesthetic agents Total 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

Total length of stay (discharge days) Total discharges x100 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
