Abstract
Background
Pre-transplant vaccination is recommended for patients undergoing solid organ transplantation (SOT). While appropriate vaccination protocols are implemented at some facilities, transplantation is sometimes performed with inadequate preoperative vaccine management. Vaccination rates vary across facilities, but those of SOT centers in Japan have never been investigated. This study aimed to conduct a nationwide questionnaire survey to assess pre- and post-transplant vaccination policies among SOT facilities in Japan.
Methods
The survey was conducted from September to November 2022. All registered (n = 221) solid organ (namely, the lungs, liver, kidneys, pancreas, heart, and small intestine) transplant facilities were asked to complete a web-based survey.
Results
The survey response rate was 70.2 %. Live and inactivated vaccines were recommended at 64.9 % and 68.9 % of the responding facilities, respectively. The following vaccines were incorporated into the vaccination protocols of facilities: pneumococcal vaccine, 31.7 % (13-valent pneumococcal conjugate vaccine) and 65.4 % (23-valent pneumococcal polysaccharide vaccine); hepatitis B virus vaccine, 67.3 %; severe acute respiratory syndrome coronavirus 2 vaccine, 73.1 %; influenza vaccine, 73.1 %; and zoster vaccines, 23.1 %. The reasons for unresponsiveness to vaccinations included inadequate time before transplantation (60.3 %), cost burden (41.1 %), high number of vaccinations (21.9 %), no recognition of the need for vaccination (17.9 %), and the requirement to explain the need for vaccination (15.2 %).
Conclusions
Our study revealed gaps in vaccination practices across nationwide facilities in Japan. The findings indicate the importance of promoting scheduled efficiency and encouraging the national health system to reduce vaccine costs with the support of public subsidies.
