Most of the GLs are evidence-based
Slide 3
Motivations for non compliance
Inter-patients variability
Low evidence level
Recommendations derived from multiple studies
Trials are performed in “optimal” conditions
Unclear or ambiguous purpose
GL evaluation is necessary
The AHA Guidelines for Ischemic stroke: a full evaluation study
effectiveness
cost
compliance analysis
Slide 7
GL and EPR
When detecting non-compliance
It’s a very GL-tailored choice
time-intensity of the user-computer interaction
time-specificity of the GL recommendations
In our case
after the acute phase (6 hours from the symptoms onset)
after the sub-acute phase
at the discharge
at the user request
Detecting non-compliance
Detecting non-compliance
At discharge
368 patients
NCR computed for each patient
(NCR=non compliance rating, i.e. the number of tasks recommended by the guideline, but that were not executed)
NCR range: 0 – 47
Analysis of the
effectiveness

Slide 15
Slide 16
Analysis of the
costs
Compliance/Cost evaluation
A causal model for cost evaluation
Attention to possible biases
Cost components (Euro)
Multivariate regression
Analysis of the
non-compliances
Non-Compliance distribution
Slide 25
Analysing specific non-compliances
Analysing specific non-compliances
Analysing specific non-compliances
Conclusion
too many non-compliances are still related to physicians’ resistance
a better education is needed to remove some behavioural and cultural biases
how to improve compliance:
demonstrating that compliance improves health outcomes and/or cost effectiveness ratio
illustrating the adverse effect of non-compliance on the outcomes.
analysing non-compliances and their motivations should
foster healthcare administrator to adopt adequate technological solutions (for example workflow management systems, if non-compliances are related to organisational pitfalls).
help designers of decision support systems to improve their tools with specific and more impressive reminds about particularly critical recommendations.
the role of the information technology is fundamental
without an efficient information system, it is impossible to perform a detailed analysis on the non-compliances.
