RHIT exam prep: computations
questions with correct answers
inpt daily census - Answer-# of pts present at census taking time each day, plus any pts
who were both admitted and discharged after the previous day's census taking time
rate - Answer-measure used to compare an event over time; # of times an event did
happen (numerator) with the # of times an event could have happened (denominator)
ratio - Answer-calculation found by dividing one quantity by another
total length of stay - Answer-total # of pt days calculated by subtracting the date of
admission from the date of discharge
average length of stay - Answer-total length of stay (discharge days)/ total discharges
incidence rate - Answer-rate describing the probability or risk of illness in a population
over a period of time
average daily inpt census - Answer-total inpt svc days for a period/total # of days in the
period
total bed count day - Answer-sum of inpt bed count days for a specified period
bed count day - Answer-unit of measure denoting 1 inpt bed set up & staffed for use in 1
24 hr period.
bed turnover rate (direct formula) - Answer-# of discharges including deaths for a
period/average bed count during the same period
case mix formula - Answer-sum of weights of MS-DRG for pt's discharged during a
given period/total # of pt's discharged (calculate to 4 decimal places)
Gross (hospital) death rate - Answer-# of inpt deaths, including NB, in a period * 100/ #
of discharges, including all deaths, in the same period
fetal autopsy rate - Answer-autopsies performed on intermediate and late fetal deaths
for a period*100/ total intermediate and late fetal deaths for the same period
net autopsy rate - Answer-total autopsies on inpt deaths for a period *100/total inpt
deaths - unautopsied coroners cases
adjusted hospital autopsy rate - Answer-total hospital autopsies*100/total # of deaths of
hospital pts whose bodies are available for autopsy
