The deterioration in the circumstances of the economy and human resources for hospitals and medical industry is now broadly recognized. We succeeded in reducing the assessed loss of the Otolaryngology Department Outpatient Clinic, which resulted in a gain of over 75% profit through the cooperation of the doctors and office staff. It was assumed that the communication and knowledge management between doctors and office staff was important. While this project was planned by a doctor, it was found that creative suggestions and ideas from office staff as professionals also had a desirable effect. It appears that the resolution of problems by establishing procedures of good communication and knowledge management leads to better quality of medical treatment and would ultimately raise awareness, resulting in a better hospital and more desirable workplace.
