Background. During the last century, national public health institutes (NPHIs) emerged to address enduring and emergency public health challenges. Outbreaks have often compelled countries to establish NPHIs. Likewise, the Covid-19 pandemic may inspire countries to create or strengthen NPHIs. Despite their historic legacies and contributions to public health, no review of NPHI literature has been published to date. The aim of this scoping review is to provide an overview of the NPHI literature published since 2000 and map characteristics of articles including format, authorship, geographic focus, methods, language, and focal topic. We also investigate whether the NPHI literature addresses public health capacity building domains. Finally, the study identifies gaps and areas for future research. Methods. The scoping review was guided the Arksey and O’Malley methodological framework and utilized the PRISMA-ScR checklist. The search was conducted in Medline OVID and Scopus databases. Data extraction involved mapping article characteristics and reviewing public health capacity building framework domains. Results. The search yielded 5731 records. A total of 43 articles met the study eligibility criteria. Articles were published in English, Spanish, French and Russian including diverse perspectives and experiences emanating from more than 20 countries in Africa, Europe, North America and South America. Most articles were formatted as commentaries. Only three reported methods or collected primary data. Articles topics included organizational structure, networks, research, funding, and governance. Conclusion. Findings reveal a longstanding international interest in leveraging NPHIs to address complex public health challenges. Lack of studies reporting methods reveals the need for future research to utilize quantitative and qualitative methods. The NPHI literature addresses topics concerning public health capacity building which underscores NPHIs’ ability to tackle global and national public health threats. Many articles in this review recommend investment in NPHIs as a strategy to respond to crises and strengthen countries’ public health systems.
