Abstract

PURPOSE
The purpose of the study is to find whether there is any effect on shortening the length of stay of long term patients due to issuing of hospitalization sheets by emergency department.
METHODS
For the investigation, 27,948 patients who resided in hospitals over 6 hours from 2006 to 2007 were chosen as the subjects. The main materials for the investigation were various time variables according to the medical records. For the verification of each factor, Student's t-test and Pearson' correlation coefficient were used.
RESULTS
There was statistically significant difference in regard to length of stay (p<0.01). The departments related to internal medicine showed that they required longer times in every aspect compared to those of non-internal medicine. There were statistically significant differences (p<0.01) in regard to the time of patients' length of stay and the time of issuing sheets for hospitalization according to the numbers of related department. However, there was no meaningful difference in regard to the waiting time for hospitalization.
CONCLUSION
In conclusion, in the cases of long term patients who stayed over 6 hours in 2007 when the random sheets for hospitalization were issued by emergency department, the length of stay was significantly reduced. It was found that the time was more increased in the departments of internal medicine than the departments of noninternal medicine and when the related sub departments increased.
