简要总结
This study seeks to understand how to support community health workers (CHWs) to improve routine vaccination rates in high-need areas by testing a two-part intervention. The first part of the intervention is a digital training provided to CHWs, which includes videos and job aids on vaccine education to support patient communication. The second part of the intervention is a patient-facing chatbot that CHWs can share with their patients. The chatbot is designed to answer patient questions about routine immunization. The intervention will be implemented in two sub-counties in Migori County Kenya (Awendo and Nyatike) that Lwala Community Health Alliance has identified as high need with respect to vaccine education. We hypothesize that the intervention will increase knowledge about routine immunization among CHWs and patients, increase vaccine acceptance, intent-to-vaccinate, and vaccination rates among patients in the treatment group.
详细描述
Background:
Immunization programs in Sub-Saharan Africa have made progress in recent decades, yet coverage remains low overall for some childhood vaccines. Immunization is one of the most powerful and cost effective public health interventions. In addition to saving lives, vaccination can greatly reduce the burden of illness and disability from vaccine preventable diseases, and contribute to improving child health and welfare, as well as reducing hospitalization costs. Yet, globally, mistrust in childhood vaccinations increased during the COVID-19 pandemic. Vaccine hesitancy in Kenya is driven by multiple interrelated and interconnected factors, including mistrust in health systems and vaccine misinformation which has grown during the global COVID-19 pandemic.
Community Health Workers (CHWs) are vital to global vaccination efforts, both in the distribution and logistical support, but also in promoting vaccine acceptance. Now more than ever, CHWs face barriers as vaccine educators including the proliferation of misinformation, lack of reliable, up-to-date information, and limited training in effective communication.
Aim:
Researchers at Stanford University's Center for Health Education and the Lwala Community Health Alliance are partnering to investigate how to better support CHWs to improve routine vaccination rates in high-need areas by testing a two-part intervention. The first part of the intervention is a digital training provided to CHWs, which includes videos and job aids on vaccine education. The second part of the intervention is a patient-facing chatbot that is designed to provide patients with key information about routine immunizations with the intent of increasing patient knowledge about vaccines, vaccine acceptance, and vaccination rates.

结局指标
主要结局
CHW vaccine knowledge
时间窗: Collected after roughly 1 month of exposure to the training content
Knowledge about routine childhood vaccines based on a set of 15 knowledge questions draw directly from the digital training
CHW vaccine education preparedness
时间窗: Collected after roughly 1 month of exposure to the training content
Set of 5 Likert scale questions about preparedness to educate patients about routine childhood vaccines including 1) preparedness to answer patient questions, 2) preparedness to explain complex health topics including immunization to patients, 3) adequate access to information about vaccines and the diseases they prevent, 4) preparedness to explain the need for so many childhood vaccines, and 5) preparedness to alleviate patients' fears about vaccination.
Patient vaccine beliefs
时间窗: Collected roughly 4-6 months from CHW first exposure to the training content
Set of 5 Likert scale questions about beliefs about routine childhood vaccines regarding 1) the safety of childhood vaccines, 2) the effectiveness of childhood vaccines, 3) whether children should receive the new Malaria vaccine, 4) whether children receive too many vaccines, and 5) whether vaccination is compatible with one's personal beliefs.
