You/ the data validators
answer these questions
for each case, then click
‘save and go to next
record’. Once all the
cases are done, you can
go to case
ascertainment.

11. Case ascertainment
• In order to calculate case ascertainment, you should look at
records at your centre such as theatre logbooks, notes and
electronic records to work out who was operated upon at
your centre and why.
• Then compare this with the GlobalSurg-2 inclusion criteria.
This can be found in the GlobalSurg-2 protocol.
• Work out the number of patients who should have been
included during the 2 week validation period.
• Enter this number via the REDCap email survey link.

12. Case ascertainment 2
• The case ascertainment
survey link will be sent
to your email once you
complete the form.
• We will also remind you
to complete this every
10 days via automated
REDCap contact, so you
have the link accessible.
