Objective: As part of the revision on remuneration for medical services in 2012, a new system has been implemented to allow an additional fee for inpatient pharmaceutical services to be added to the basic hospitalization fee.
Methods: We at Kitasato University Kitasato Institute Hospital satisfied all institutional requirements for the new system and were preparing to introduce it from April 2012; however, there was concern about the increased workload due to the additional work of preparing diaries for pharmaceutical services used in calculating the additional fee.
Results: We therefore developed a database titled Diary System for Inpatient Pharmaceutical Services for the preparation and management of diaries.  This system allows pharmacists from various divisions to enter data simultaneously and realizes the unified management of records of services performed at various places in the pharmacy.
Conclusions: Since entered data are automatically reflected in the inpatient pharmaceutical service diary and the monthly summary, an advantage compared to paper diaries in terms of efficiency may be expected.  Furthermore, the monthly summary of the number of service hours by ward and service type may also be used for service analysis.
