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.

survey link will be sent to your email once you complete the form.
