クリニカルパス導入による耳科手術患者の入院日数への効果

抄録

We investigated the length of hospital stay of 256 patients who underwent otologic surgeries after introduction of the in-house protocol (group A) at the Department of Otorhinolaryngology & Head and Neck Surgery of Fukuoka University Hospital from September 2007 to August 2010, and compared it with that of 110 patients who underwent similar surgeries from January 2005 to August 2007, prior to the introduction of the protocol (group B). The average length of hospital stay of patients of group A who underwent Canal Wall Down Tympanomastoidectomy was significantly shorter than that of group B who underwent the same surgery. However, for patients who underwent conductive system reconstruction without eardrum repair, much slighter benefit was derived from use of the protocol in terms of reducing the length of hospital stay. These findings suggest that the protocol is selectively useful for reducing the overall length of hospital stay, but may require revisions for some types of surgical procedures.
