Purpose : This preliminary study was aimed to investigate potentially beneficial changes in prescription of antibiotics by use of Gram staining in an otorhinolaryngology outpatient clinic.
Methods : This study was done in a single clinic. Changes in the type and amount of antibiotics prescribed, in addition to the clinical outcomes prior to and following introduction of Gram staining, were analyzed retrospectively.
Results : Following introduction of Gram staining in 2005, the costs for antibiotics per person per year decreased to about one-fifth. The number of prescriptions per 100 patients decreased from 20.9 in 2006 to 3.6 in 2012 for macrolides, from 7.9 in 2005 to 2.4 in 2012 for third-generation cephalosporins, and increased from 1.6 in 2004 to 3.9 in 2012 for penicillins. In addition, for every 50 pediatric cases of acute sinusitis, the number of patients to whom no antibiotics were prescribed increased 9-fold and the number of patients to whom 2 or more types of antibiotics were prescribed decreased from 26 to 9 cases, while the mean period in days until resolution was shortened by 6 days.
Conclusion : The results of this pilot study suggest that the use of Gram staining for diagnosis and prescription of antibiotics in an otorhinolaryngology outpatient clinic may lead to significantly improved antibiotic prescription practices. Further study through proper controlled studies are felt to be neceesary.

Clinical training programs play an extremely important role in the new postgraduate clinical training system introduced in 2004 because facilities for clinical training now include various health-related institutions in addition to the university hospitals and special hospitals for clinical training used in the previous system. Although educational goals have been established by the Ministry of Health, Labour and Welfare, trainees may have difficulty achieving these goals, even under the guidance of staff at the various facilities. There are differences in the function and quality of health-related institutions in the community. For the practical and convenient application of educational goals, we have attempted develop a “model program” to supplement the objectives indicated by the learning goals with more specific objectives. These supplementary objectives can be modified by individual institutions. We hope that this “model program” contributes to the development of objectives for each institution and helps improve the quality of the postgraduate training system in Japan.
