Objective: The aim of the study was to determine whether it was safe to discharge children with asthma from hospital when stable on 3-hourly rather than 4-hourly doses of salbutamol.
Methodology: A retrospective study of 419 individual admissions of 359 children with asthma was undertaken. We defined a theoretical 'time ready for discharge' (TRD) for asthmatic admissions based on: (i) at least two doses of 3-hourly salbutamol and due for the third dose, (ii) no oxygen supplementation, (iii) no intravenous fluid or therapy, and (iv) time of discharge should be either before 17:30 hours or after 07:30 hours.
