Diagnostic , Therapeutic and Social Care Pathways (PDTA)
• 632 health care professional were involved • 31 reference centers• 33 patient associations
• 110 PDTA were prepared
• They cover approximately 72 – 87% of rare disease recorded in Lombardy
Since 2012 the Regional Network has promoted the development, through conferences of experts, of shared pathways for the diagnosis, treatment and social assistance to patients with rare diseaseThese pathways are intended to offer the best quality of care whereby optimizing the use of resources

Adaptative Designs: Examples
Gupta et al, J Clin Epidemiol 2011
Ranking and selection designs - “Pick-the-winner”, “drop-the-losers” designs are used for
treatment/dose selection for a subsequent randomized study)
Internal pilot designs - The sample size is calculated during the pilot phase and patients
of the pilot study are maintained in the subsequent trial
Sequential designs - Continuous sequential analyses are planned with pre-set
stopping criteria
Response-adaptative randomization designs - Possibility to adapt the study design according to preliminary
outcomes
