The effect of population size on the estimated maximum false match rate.
Estimation assumes:
• 22 years of birth dates, uniform distribution (compromise distribution).
• single-date (exact end-date) matching only of separations to residential aged care admissions.
• exact period matching to residential aged care hospital leave.
Calculations use national average hospital separation rates (2000–01) and residential aged care admission and residential aged care leave rates (2001–02) [38]. Estimates take into account the distribution of hospital episodes by length of stay.
