Where are CF Foundation-accredited care programs?
Who is followed in the Registry? Based on birth rates and CFTR allele prevalence, it is estimated that there are about 34,500 persons with CF in the United States 6% do not consent to participate in Registry ~34,500 ~31,000 100% 90% 28,983 84% Followed in the CF Foundation Patient Registry in 2015 Followed at US CF Care Centers

Can we evaluate the effectiveness of treatment?
Efficacy (clinical trials) Effectiveness (real world) Clinical Trials Design optimized to demonstrate safety and efficacy may limit generalizability Disease stage Co-morbidities Problematic respiratory infection Poor follow up Frequent visits with careful follow-up Standardization of management and outcome measures Attention to adherence Real World All who may benefit often including those excluded from trial and/or offlabel use Less frequent visits and follow-up Less standardization of management and outcome measures Longer duration of therapy Less attention to adherence
