OVERCOMING THE CHALLENGES AND ADOPTION FOR NEW USERS IN ELECTRONIC IMMUNIZATION REGISTRY IMPLEMENTATION - A CASE STUDY FROM VIETNAM—
Immunization staffs have a central role with EIRs as they are the ones who input data into the system that the systems need to function, as well as utilize the data in the system to perform their daily work. Thus, whether or not these frontline users support and use EIRs would have great impact on whether or not the system is successfully implemented and scaled up nationwide. With the launch of the National Immunization Information System (NIIS) in 2017, Vietnam has given much effort to fully integrate the electronic system and gradually transition to the complete elimination of the legacy paper system. Similar to any adoption process for successful implementation and transition, barriers and challenges by immunization staffs were carefully evaluated and prioritized to sufficiently address them. This case study, under the IDEAL Vietnam project granted to PATH by the Bill & Melinda Gates Foundation, is aimed at identifying and discussing the barriers faced by immunization staffs in Vietnam throughout the implementation process of the NIIS. It also shares the successful approaches to overcoming these barriers as well as some existing challenges that are yet to be solved. From these lessons learned in Vietnam, other countries with similar socio-technical environments may develop and adapt their own user-centered EIR implementation.
