[Purpose] We introduced subcutaneous suture with a synthetic absorption thread and examined its efficacy on surgical site infection after pancreaticduodenectomy (PD). [Method] In hour hospitals, PD was performed in a total of 69 cases from March 2006 through March 2014. They was divided into two groups-one consisting of 31 cases in which the skin wounds with staplers (non-subcutaneous suture group), and the other consisting of 38 cases in which surgical wounds were closed with subcutaneous sutures (subcutaneous suture group), and the incidence of surgical site infection (SSI) were compared between the two groups. [Result] Incidence of surface SSI occurred in eight cases (21.0%) in the non- subcutaneous suture group and three cases (9.7%) in the subcutaneous suture group (p＝0.17). The incidence of SSI was decreased in the subcutaneous suture group than in the non-subcutaneous suture group, but no statistically significant difference was observed between the two groups. However, taking into account the advantages such as the reduction of patient’s medical expenses, and the burden of ward duties, further examination with an additional number of patients was thought to be necessary.

Introduction: This study aimed to determine the trends in the use of medicines that can affect the recognition function of patients aged ≧70 years. Since 2015 when the “Safe Drug Treatment Guidelines for the Elderly” was revised, these medicines are dispensed at a community pharmacy located in a satellite city. Methods: We compared the dispensing results from 2014 to 2015-2019 and investigated the ratio of prescriptions containing the medicines that can affect the recognition function using the clinical department and medicine type. Results: Prescriptions containing medicines that can affect recognition function have been on a downward trend since 2015. During this period, the number of medicines per prescription did not decrease, and the medicines that can affect recognition function were replaced with other medicines. On the other hand, no decrease in the number of medicines that can affect recognition function was observed in internal medicine. In medicine type, the ratio of benzodiazepines drugs decreased; however, it increased again in 2019. Conclusion: There was a decreasing trend in the use of medicines that can affect recognition function of the elderly in departments other than internal medicine after 2015.
