Approach to decreasing emergency department ambulance diversion hours.
Analysis between two local Emergency Departments (EDs) suggested an oscillatory phenomenon for ambulance diversion: When one hospital went on diversion it led to a disproportionate flow of ambulance traffic to a neighboring facility that subsequently was forced to go on divert. We hypothesized if one hospital could avoid diversion status, the need for diversion could be averted in the neighboring facility. ED A secured additional resources and made a commitment to no diversion for 1 week. No changes in operations occurred in hospital B. We found no differences in ambulance runs or ED census at either facility comparing the week before, during, and after the trial. There was a dramatic decline in diversion hours from 19.7 to 1.4 and 27.7 to 0 at hospitals A and B, respectively, during the trial period (p < 0.05) compared to the weeks before and after. We conclude that reciprocating effects can be decreased with one institution's commitment to avoid diversion, thus decreasing the need for diversion at a neighboring facility.
