Effect of organizational structure of the ICU on the prognosis: open format versus semi-closed format

Introduction

In the year 2009, the organizational structure of the ICU in the Kanazawa University Hospital changed from an open to a semi-closed format ICU. The objective of this study was to evaluate the effect of this organizational change on outcome in high-risk surgical patients.

Methods

The medical records of all consecutive high-risk surgical patients admitted to the ICU from 2006 to 2009 (open format, n = 1,598) and from 2009 to 2012 (semi-closed format, n = 1,521) were reviewed. Parameters studied were mortality and ICU length of stay.

Results

Mortality of ICU patients was 9.9% in the open format group and 6.6% in the closed format group (P 0.05). The average length of hospital stay was 4.9 days in the open format group and 4.8 days in the closed format group.

Conclusion

Our results suggest that a semi-closed format is a more favorable setting than an open format to improve mortality in the ICU and to warrant safe outcome in this patient group.
