Reminder: Tomorrow Change will be hosted by the UW Department of Global Health in the *Harris Hydraulics* <http://uw.edu/maps/?hhl> building. ----- Please join us for the Change Seminar this week on *Tuesday 10/24/2017* in the large conference room of *Harris Hydraulics* from *12-1 pm*. Note the room change!! *Who:* Samantha Dolan (UW SPH DGH) *What:* *Electronic immunization registries: Understanding fidelity, sustainability, and potential for scale-up in low-resource settings using implementation science research* *When:* Tuesday Oct 24 *Where:* 12pm in the Large Conference Room of the Harris Hydraulics building (DGH) *Abstract:* Open source software is becoming more widely used to digitalize the collection of routine program and client-level data amongst health programs in low-resource settings. However despite being “free”, these software products require significant resources to update, maintain, and scale-up before becoming effective health information systems. Using the example of electronic immunization registries built using Open Smart Register Platform (OpenSRP), we will present implementation science methods for understanding the fidelity, acceptability, cost, and impact of these types of systems and how findings could be used to drive investments and policy-making. *Bio:* Samantha is a PhD student in the Department of Global Health. She works as a research and evaluation advisor at UW’s International Training and Education Center for Health (I-TECH) and is also an intern at PATH for the Better Immunization Data initiative. Her work aims at building and scaling electronic immunization registries in Kenya, Tanzania, and Zambia. She is also involved with developing guidance on how to conduct health information system evaluations in low-resource settings and designing a surveillance system for healthcare-associated infections at acute-care hospitals.
