Work out hospital length of stay estimate instantly with clear inputs, formula shown and shareable results.
Combines the uncomplicated stay with the probability-weighted extra days from complications to give an expected length of stay.
Expected value
Expected stay = base days + probability of complication x extra days
Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
Length of stay distributions are right skewed, so the mean exceeds the median that most patients experience.
Multiplying expected stay by admissions gives the bed days a service needs to fund.
