Background: A significant proportion of general surgery emergency procedures are conducted after-hours in regional centres. The acute surgical unit (ASU) model reduces the number of after-hours operations performed. We review the burden of emergency surgery in a regional centre and assess what components of the ASU model would benefit regional hospitals.
Methods: Retrospective analysis was performed on data for all emergency cases performed at Latrobe Regional Hospital (LRH) over a 1-year period. Time into and out of theatre was used to determine total theatre usage and if the operation occurred after-hours. ED triage time to theatre and start time for appendicectomy was compared to data from our metropolitan referral hospital, Monash Medical Centre (MMC), which has employed an ASU.
Results: General surgery emergency cases in regional areas are regular and predictable with a median of two emergency cases performed, and a mean theatre time of 156 min per day at LRH. On weekdays, 43.1% (n = 503) of emergency cases were done in the evening (18.00-24.00 hours), compared to 20.3% (n = 217) on weekends when an emergency theatre is available during the day. LRH performed more appendicectomies after-hours than MMC over a 1-year period.
Conclusion: Regional centres have a significant burden of general surgery emergency procedures; of which the number performed after-hours is comparable to metropolitan centres. The number of procedures and theatre time required by these cases justify a dedicated emergency theatre in-hours similar to metropolitan ASU models and this would reduce emergency operating after-hours.
