Background：A regular vaccination schedule for the 23-valent pneumococcal polysaccharide vaccination targeting elderly individuals and others has been in effect since October 2014 in Japan. This study mainly examined whether a regular vaccination schedule and introduction of a vaccination status checkbox in electronic medical records increased the vaccination rates. Methods：Subjects were inpatients and outpatients who received the pneumococcal vaccine in the Department of General Medicine at Juntendo University Hospital between April 1, 2011 and March 31, 2016. The vaccination rates in individuals ≥ 65 years old before and after introducing the regular vaccination schedule and checkbox were investigated. Results：A total of 365 people ≥ 65 years old were vaccinated. The vaccination rate (1.3%) for individuals ≥ 65 years old after introducing the regular vaccination schedule was significantly higher than the vaccination rate (0.5%) before introducing the schedule (p<0.05). However, the vaccination rate significantly decreased after the introduction of the checkbox to the electronic medical records (p<0.05). Conclusions：Although the regular vaccination schedule was effective and should be continued., we were unable to show an improvement of the vaccination rate by the introduction of the checkbox to indicate a patientʼs vaccination status in the electronic medical records. We feel that the introduction of a check box along with other items such as an alert system would be more effective.
