There are a wide variety of approaches to screening and in this paper, we propose that a bioethical framework is required to determine the most appropriate screening protocol for a population. This framework depends on the detailed evaluation of the ethical consequences of all screening outcomes and placing these in the context of the genetic profile of the population screened, the geography of the region and the healthcare resources available.

In this study, we explored the process of adhering to aerosol therapy from the perspective of both adolescents with CF and their parents. Interviews were conducted individually with six adolescents and six parents, informed by accurate adherence data from an electronically chipped, aerosol device. Interview transcripts from audio-recordings were analyzed using grounded theory method (GTM). Major themes revealed differences in perspective between parent and adolescent, with this relationship mediating the cognitive and emotional processes that play a significant role in adherence behavior. These processes are further influenced by interactions with the aerosol therapy treatment regimen, device characteristics, and the context in which adherence is taking place. Parents and adolescents have different views of treatment and how to manage ...

As newborn screening rolls-out across Europe, CF centres are increasingly caring for cohorts of patients who have minimal lung disease on diagnosis. With the introduction of mutation-specific therapies and the prospect of truly personalised medicine, patients have the potential to enjoy good quality of life in adulthood with ever-increasing life expectancy. The landmark Standards of Care published in 2005 set out what high quality CF care is and how it can be delivered throughout Europe. This underwent a fundamental re-write in 2014, resulting in three documents; center framework, quality management and best practice guidelines. This document is a revision of the latter, updating standards for best practice in key aspects of CF care, in the context of a fast-moving and dynamic field. In continuing to give a broad overview of the standards expected for newborn screening, diagnosis, preventative treatment...

These infants are classified as CF transmembrane conductance regulator-related metabolic syndrome (CRMS) in the US and CF screen positive, inconclusive diagnosis (CFSPID) in other countries. Diagnostic and management decisions of these infants are challenges for CF healthcare professionals and stressful situations for families. As CF NBS has become more widespread across the world, increased information about the epidemiology and outcomes of these infants is becoming available. These data were reviewed at the 2015 CF Foundation Diagnosis Consensus Conference, and a harmonized definition of CRMS and CFSPID was developed. At the consensus conference, participants reviewed published and unpublished studies of CRMS/CFSPID and used a modified Delphi methodology to develop a harmonized approach to the definition of CRMS/CF...

The aim of this study was to provide an update on NBS for CF in Europe and assess performance against the standards. Questionnaires were sent to key workers in each European country. In 2016, there were 17 national programmes, 4 countries with regional programmes and 25 countries not screening in Europe. All national programmes employed different protocols, with IRT-DNA the most common strategy. Five countries were not using DNA analysis. In addition, the processing and structure of programmes varied considerably. Most programmes were achieving the ECFS standards with respect to timeliness, but were less successful with respect to sensitivity and specificity. There has been a steady increase in national CF NBS programmes across Europe with variable strategies and outcomes that reflect the different approaches.

Newborn screening and an evolving understanding of CF genetics have prompted a reconsideration of the diagnosis criteria. To improve diagnosis and achieve standardized definitions worldwide, the CF Foundation convened a committee of 32 experts in CF diagnosis from 9 countries to develop clear and actionable consensus guidelines on the diagnosis of CF and to clarify diagnostic criteria and terminology for other disorders associated with CFTR mutations. An a priori threshold of ≥80% affirmative votes was required for acceptance of each recommendation statement. After reviewing relevant literature, the committee convened to review evidence and cases. Following the conference, consensus statements were developed by an executive subcommittee. The entire consensus committee voted and approved 27 of 28 statements, 7 of which needed revisions and a...

Aim To assess views on the palatability of flucloxacillin oral liquid and identify factors associated with successful administration. Methods A mixed methods study which included a structured review of online forums and a survey of parent/carers of children with cystic fibrosis (CF) to obtain parent/carer views on the administration of flucloxacillin oral liquid. Results A total of 18 strategies to aid the administration of flucloxacillin suspension to children were identified on 10 different public online forums.

Strategies to aid administration of unpalatable medicines have been reported, however there has never been a systematic approach to gathering views of many parents/carers all administering the same medication to the same population of children.

NBS for cystic fibrosis is a cost-effective strategy and, if standards of care are fully implemented and robust management pathways are in place, has a positive effect on clinical outcomes. In the past decade, NBS has undergone rapid expansion and an unprecedented number of infants with cystic fibrosis have access to early diagnosis and care. Cystic fibrosis NBS has now moved on from the development phase and is entering an era of consolidation. In the future, research should focus on the rationalisation and optimisation of existing programmes, with particular attention to bioethical implications such as unwanted detection of carriers and inconclusive diagnoses.
