Disclaimer: ACORN-lite protocols and CRFs are freely and publicly available. ACORN protocols were developed by a team of ACORN investigators with funding from Wellcome and Fleming Fund. Please kindly contact the ACORN investigators (acorn@tropmedres.ac) if you intend to use these protocols / CRFs for data collection so they are aware where these are being used, but especially for discussion and support. The ACORN investigators are very experienced with implementation and troubleshooting of these protocols / CRFs and in addition can support setting up a local database and dashboard for data storage and feedback.
