Purpose: Emergency departments (ED) are always overcrowded. Overcrowding is an important problem associated with emergency department treatment and patient satisfaction. Overcrowding can be caused by specific and complex issues and is affected by multiple influences. In an effort to reduce the degree of overcrowding, we evaluated relationships within the SMS (short message service) specialist`s notification system.
Methods: This study involved establishment of a SMS specialist`s notification system and other activity for resolution of emergency department overcrowding. We conducted a comparative analysis of ED patients from January 2010 to December 2010, before establishment of the system, and from January 2011 to December 2011, after establishment of the system. Data on ED patients were obtained from electronic medical records and the clinical data warehouse. Data were compared for mean length of stay and patient admission number.
Results: Results of comparison showed that the mean length of stay for discharge, admission, operation, and transfer had been effectively reduced. Mean residence time for patients in each administration sector was reduced 80.3, 462.3, 127.3, and 89.3 minutes, respectively, after overcrowding had been diminished. Significant differences for mean residence time were observed in each sector p<0.001). In addition, comparison of before and after adoption of the SMS specialist`s notification system for each clinical department showed that mean length of stay of patients admitted to the emergency department was significantly shorter after its adoption.
Conclusion: By establishing a SMS specialist notification system, overcrowding can be resolved and length of stay can be shortened, which would result in improved satisfaction of both patients and emergency department professionals.
