Quality Control
Actigraph Data Screening Checking
Ideally, same person would screen all the data
Regular reliability checks should be conducted by managers and
investigators
IPEN-CC will also check a % of all files and encourage you to also
send ambiguous files for consultation
Nobody becomes an expert in a few months so we encourage and expect to be
consulting you about ambiguous files and cases
Database Management
Recruitment database checked weekly for cases that have fallen between the
cracks (next action not coded, dates are mistyped, person not being contacted
anymore, etc.)
Query of outstanding units prepared weekly and each is reviewed to be sure
that appropriate action is being taken to retrieve
