Background Between 2002 and 2006 France launched a national cystic fibrois (CF) newborn screening program; organized a network of specialized CF care centers; and issued CF diagnostic and treatment standards. To continue to build on this success in 2007 the Cystic Fibrosis Center of Expertise for Rare Diseases (CF CERD) of Nantes-Roscoff in partnership with the French CF Society, the French CF Association (Vaincre la Mucoviscidose), and all CF center leaders from across the country agreed to pursue center-level improvement in medical outcomes for people with CF by adapting the U.S. Cystic Fibrosis Foundation’s (US CFF) national initiative, Accelerating the Rate of Improvement in CF Care . To launch the Program to Improve Results and Expertise in CF (le Programme d’Amélioration des Résultats et de l’Expertise en Mucoviscidose - PHARE-M), French leaders pursued mentorship and guidance from leaders at the US CFF, the Dartmouth Institute (TDI), and clinical care teams at CF centers across the U.S. Methods The following activities enabled the Nantes-Roscoff CF CERD team members and a parent, involved with the French CF Association board and a quality engineer by training, to gain the leadership and quality improvement knowledge and skills necessary to implement the PHARE-M program: 1) regularly attending national meetings, tracking publications, and leveraging existing partnerships; 2) completing two sabbaticals to visit U.S. CF centers and enrolling in academic and professional training courses; and, 3) inviting US CFF and TDI leaders to France to meet key opinion leaders and frontline teams. Conclusions The Nantes-Roscoff CF CERD team successfully adapted the US CFF’s initiative to accelerate improvement in CF care by establishing a partnership with U.S. leaders to communicate and exchange strategies and lessons learned; intentionally studying and adapting the Clinical Microsystems approach to quality improvement; and learning directly from the experience of frontline teams in the U.S. They continue to partner with U.S. leaders and are seeking to collaborate with European colleagues to continue to improve care for individuals with CF and their families across Europe.

BackgroundIvacaftor is the first cystic fibrosis transmembrane conductance regulator (CFTR) modulator demonstrating clinical benefit in patients with cystic fibrosis (CF). As ivacaftor is intended for chronic, lifelong use, understanding long-term effects is important for patients and healthcare providers.ObjectiveThis ongoing, observational, postapproval safety study evaluates clinical outcomes and disease progression in ivacaftor-treated patients using data from the US and the UK CF registries following commercial availability.MethodsAnnual analyses compare ivacaftor-treated and untreated matched comparator patients for: risks of death, transplantation, hospitalisation, pulmonary exacerbation; prevalence of CF-related complications and microorganisms and lung function changes in a subset of patients who initiated ivacaftor in the first year of commercial availability. Results from the 2014 analyses (2 and 3 years following commercial availability in the UK and USA, respectively) are presented here.ResultsAnalyses included 1256 ivacaftor-treated and 6200 comparator patients from the USA and 411 ivacaftor-treated and 2069 comparator patients from the UK. No new safety concerns were identified based on the evaluation of clinical outcomes included in the analyses. As part of safety evaluations, ivacaftor-treated US patients were observed to have significantly lower risks of death (0.6% vs 1.6%, p=0.0110), transplantation (0.2% vs 1.1%, p=0.0017), hospitalisation (27.5% vs 43.1%, p<0.0001) and pulmonary exacerbation (27.8% vs 43.3%, p<0.0001) relative to comparators; trends were similar in the UK. In both registries, ivacaftor-treated patients had a lower prevalence of CF-related complications and select microorganisms and had better preserved lung function.ConclusionsWhile general limitations of observational research apply, analyses revealed favourable results for clinically important outcomes among ivacaftor-treated patients, adding to the growing body of literature supporting disease modification by CFTR modulation with ivacaftor.EU PAS registration numberEUPAS4270

The Cystic Fibrosis Foundation Patient Registry (CFFPR) is an ongoing patient registry study that collects longitudinal demographic, clinical, and treatment information about persons with cystic fibrosis (CF) in the United States. CF is a life-shortening genetic disorder that occurs in approximately 1 in 3,500 births in the United States. High-quality observational data is important for clinical research, quality improvement, and clinical management. To describe the data collection, patient population, and key limitations of the CFFPR. Inclusion criteria for the CFFPR include diagnosis with CF or a CFTR-associated disorder, care at an accredited care center program, and provision of informed consent. Data from clinic visits and hospitalizations are collected through a secure website. Loss to follow-up and generalizability were examined using several methods. The accuracy of CFFPR data was evaluated with an audit of 2012 CFFPR data compared to the medical record. Since 1986, the CFFPR contains the records of 48,463 individuals with CF. Participation among individuals seen at accredited care centers is high, and loss to follow-up is low. An audit of 2012 CFFPR data suggests that the CFFPR contains 95% of clinic visits and 90% of hospitalizations found in the medical record for these patients, and nearly all of the audited fields were highly accurate. Registries such as the CFFPR are important tools for research, clinical care, and tracking incidence, mortality and population trends.

Non-tuberculous mycobacteria (NTM) are ubiquitous environmental organisms that can cause chronic pulmonary infection, particularly in individuals with pre-existing inflammatory lung disease, such as cystic fibrosis (CF). Pulmonary disease (PD) caused by NTM has emerged as a major threat to the health of individuals with CF, but remains difficult to diagnose and problematic to treat. In response to this challenge, the US Cystic Fibrosis Foundation (CFF) and the European Cystic Fibrosis Society (ECFS) convened a panel of 19 experts to develop consensus recommendations for the screening, investigation, diagnosis and management of NTM-PD in individuals with CF. PICO (population, intervention, comparison, outcome) methodology and systematic literature reviews were employed to inform draft recommendations, which were then modified to achieve consensus and subsequently circulated for public consultation within the USA and European CF communities. We have thus generated a series of pragmatic, evidence-based recommendations as an initial step in optimising management for this challenging condition.

Pulmonary disease caused by NTM has emerged as a major threat to the health of individuals with CF but remains difficult to diagnose and problematic to treat. In response to this challenge, the US Cystic Fibrosis Foundation (CFF) and the European Cystic Fibrosis Society (ECFS) convened an expert panel of specialists to develop consensus recommendations for the screening, investigation, diagnosis and management of NTM pulmonary disease in individuals with CF. Nineteen experts were invited to participate in the recommendation development process. Population, Intervention, Comparison, Outcome (PICO) methodology and systematic literature reviews were employed to inform draft recommendations. An anonymous voting process was used by the committee to reach consensus. All committee members were asked to rate each statement on a scale of: 0, completely disagree, to 9, completely agree; with 80% or more of scores between 7 and 9 being considered ‘good’ agreement. Additionally, the committee solicited feedback from the CF communities in the USA and Europe and considered the feedback in the development of the final recommendation statements. Three rounds of voting were conducted to achieve 80% consensus for each recommendation statement. Through this process, we have generated a series of pragmatic, evidence-based recommendations for the screening, investigation, diagnosis and treatment of NTM infection in individuals with CF as an initial step in optimising management for this challenging condition.

While cholesterol levels are typically quite low, isolated triglycéride elevation has been noted. Because CF patients are at low risk for atherosclerotic cardiovascular disease, it is not clear that lipid elevation requires treatment in this population, and there are no data regarding the efficacy or safety of medical therapy for CF dyslipidemia.

The Cystic Fibrosis (CF) Foundation developed clinical care guidelines for the prevention of Pseudomonas aeruginosa infection, the treatment of initial P. aeruginosa infection, and the use of bronchoscopy to obtain routine airway cultures in individuals with CF. A multidisciplinary committee developed questions about the prevention and treatment of initial P. aeruginosa infection and the use of bronchoscopy to obtain routine airway cultures. The outcome measure of interest was cultures without P. aeruginosa growth. Systematic reviews of PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials were conducted in May 2012 and August 2013. Searches combined controlled vocabulary terms and text words for CF and terms relevant to each question. The entire committee reviewed the evidence, and final recommendation statements were graded using the U.S. Preventive Services Task Force system. Recommendation 1: The CF Foundation strongly recommends inhaled antibiotic therapy for the treatment of initial or new growth of P. aeruginosa from an airway culture (certainty of net benefit, high; estimate of net benefit, substantial; grade of recommendation, A). The favored antibiotic regimen is inhaled tobramycin (300 mg twice daily) for 28 days. Recommendation 2: The CF Foundation recommends against the use of prophylactic antipseudomonal antibiotics to prevent the acquisition P. aeruginosa (certainty of net benefit, moderate; estimate of net benefit, zero; grade of recommendation, D). Recommendation 3: The CF Foundation recommends routine oropharyngeal cultures rather than bronchoalveolar lavage cultures obtained by bronchoscopy in individuals with CF who cannot expectorate sputum to determine if they are infected with P. aeruginosa (certainty of net benefit, moderate; estimate of net benefit, moderate; grade of recommendation, B).

Abstract Rationale Lung transplantation offers the only survival option for patients with cystic fibrosis (CF) with end-stage pulmonary disease. Infection with Burkholderia species is typically considered a contraindication to transplantation in CF. However, the risks posed by different Burkholderia species on transplantation outcomes are poorly defined. Objectives To quantify the risks of infection with Burkholderia species on survival before and after lung transplantation in patients with CF. Methods Multivariate Cox survival models assessed hazard ratios of infection with Burkholderia species in 1,026 lung transplant candidates and 528 lung transplant recipients. Lung allocation scores, incorporating Burkholderia infection status, were calculated for transplant candidates. Measurements and Main Results Transplant candidates infected with different Burkholderia species did not have statistically different mortality rates. Among transplant recipients infected with B. cenocepacia, only those infected with nonepidemic strains had significantly greater post-transplant mortality compared with uninfected patients (hazard ratio [HR], 2.52; 95% confidence interval [CI], 1.04–6.12; P = 0.04). Hazards were similar between uninfected transplant recipients and those infected with B. multivorans (HR, 0.66; 95% CI, 0.27–1.56; P = 0.34). Transplant recipients infected with B. gladioli had significantly greater post-transplant mortality than uninfected patients (HR, 2.23; 95% CI, 1.05–4.74; P = 0.04). Once hazards for species/strain were included, lung allocation scores of B. multivorans–infected transplant candidates were comparable to uninfected candidate scores, whereas those of candidates infected with nonepidemic B. cenocepacia or B. gladioli were lower. Conclusions Post-transplant mortality among patients with CF infected with Burkholderia varies by infecting species. This variability should be taken into account in evaluating lung transplantation candidates.

Context: Scientific and therapeutic advances Remarkable biomedical research advances have led to innovative and increasingly effective therapies. We highlight several scientific milestones in elucidating the pathophysiology of cystic fibrosis (CF) and review the therapies that have become available over the past 20 years. Impact of the quality improvement initiative In 2002, the CF Foundation launched a multifaceted quality improvement initiative to accelerate improvement in CF care. We present evidence of substantial improvement in process measures, such as more consistent outpatient follow-up, and key medical outcomes, including survival, pulmonary function and nutritional status. Critical success factors We offer our perspective on factors critical to the success of the quality improvement initiative, including a compelling strategic plan and the commitment of the CF Foundation to its implementation; the investment in building improvement capacity at CF care centres; the engagement of people with CF and their families as partners; and the integration of quality improvement into the existing CF care framework. Directions for the next decade In addition to a continued investment in building and sustaining improvement capacity at CF care centres, and deeper patient engagement, we will address the oppressive treatment burden. We will also complement the measurement of clinical outcomes with patient reported outcomes and healthcare costs for a balanced assessment of the quality and value of care. Conclusions Major advances in basic science and therapeutic development coupled with improvements in healthcare delivery have resulted in striking gains in medical outcomes for people with CF.

RationaleA previous analysis found significantly higher lung function in the US paediatric cystic fibrosis (CF) population compared with the UK with this difference apparently decreasing in adolescence and adulthood. However, the cross-sectional nature of the study makes it hard to interpret these results.ObjectivesTo compare longitudinal trajectories of lung function in children with CF between the USA and UK and to explore reasons for any differences.MethodsWe used mixed effects regression analysis to model lung function trajectories in the study populations. Using descriptive statistics, we compared early growth and nutrition (height, weight, body mass index), infections (Pseudomonas aeruginosa, Staphylococcus aureus) and treatments (rhDnase, hypertonic saline, inhaled antibiotics).ResultsWe included 9463 children from the USA and 3055 children from the UK with homozygous F508del genotype. Lung function was higher in the USA than in the UK when first measured at age six and remained higher throughout childhood. We did not find important differences in early growth and nutrition, or P.aeruginosa infection. Prescription of rhDNase and hypertonic saline was more common in the USA. Inhaled antibiotics were prescribed at similar levels in both countries, but Tobramycin was prescribed more in the USA and colistin in the UK. S. aureus infection was more common in the USA than the UK.ConclusionsChildren with CF and homozygous F508del genotype in the USA had better lung function than UK children. These differences do not appear to be explained by early growth or nutrition, but differences in the use of early treatments need further investigation.
