Conclusion
• During the first 9 years the club made huge
progress in gaining new experts, accepting
more severe CTO-cases increasing success
rate, most likely by watching, teaching and
adopting accepted techniques (convergence
of interventional aproach).
• Registry and monitoring confirms high
credibility of our data
Credibility check of the online
EuroCTO-registry 2008-14
• Logical checks on data ( predefined value
ranges)
• Logical consistency-tests with respect to
other data fields
• Automatic warnings when data are missing
2015 and on:
10 % reabstraction of CTO records
(n = 250/ year), masked and
reviewed by a second abstractor
At random : „ your patient was
selected for monitoring“
Automatic export of registry parameters
9
parameters to be checked
by reviewer
Results of Monitoring (n=202)
Successful wire 2015
Did Monitoring influence data?
Monitored Registry
• Only few entries with overt disagreement
• No relevant change in grading of severity
i.e.high credibility of data
• Good source for publications of the clubs
experience, open to all members
