The population of Saitama City is aging, and collaboration between community pharmacies and hospitals is becoming increasingly important for comprehensive community care. We conducted a questionnaire survey to promote pharmacy collaboration among insurance pharmacy pharmacist members who belong to Saitama City Pharmaceutical Association. The questionnaire collection rate was 39.8 95 CI 34.5 45.1). Many respondents wanted to hold regular study sessions to increase transparency between insurance pharmacy pharmacists and hospital pharmacists. As insurance pharmacy pharmacists and hospital pharmacists develop mutual understanding, information sharing using ICT would not only reduce the work burden on doctors and insurance pharmacy pharmacists, it would also promote local comprehensive care, including the relationship with regional insurance pharmacies, participation in management and joint guidance at discharge. In order to nurture current pharmacists in practice and future pharmacists, it is very important to promote collaboration between community pharmacies and hospitals in the region.
