Abbreviations: A&F= audit and feedback, CDS= computerized decision support, CI= confidence interval, CR= cardiac rehabilitation.
a)
Observed concordance during first 3 months of study period.
b)
Observed concordance after baseline period until end of study.
c)
Odds ratio of improvement in guideline concordance after receiving the A&F intervention for 1 year versus no intervention; adjusted for patients’ age, gender, indication for CR, and clinics’ type and size.
d)
Patients for whom the CDS could not provide advice caused by missing data and/or it was not recorded whether the therapy was included in the patients’ CR program.
