BackgroundPeople with cystic fibrosis (CF) are susceptible to respiratory infection with Pseudomonas aeruginosa (PA), which may become chronic if initial eradication fails. Environmental acquisition and person-to-person transmission can occur. Respiratory PA infection is associated with increased mortality and more hospitalisations. This may cause patients and families anxiety and lead them to adopt preventive measures which may be ineffectual and intrusive. It is not possible to hold a conventional focus group to explore these issues because people with CF cannot meet together due to the risk of cross-infection.ObjectiveTo explore the perceptions of first respiratory infection with PA in people with CF and those close to them.DesignWe designed an online survey, to maximise accessibility and avoid the risk of cross-infection. This established the respondent's relationship with CF, asked 3 open questions about perceptions of PA and a final question about the prioritisation of research. Responses were analysed using a structured, iterative process. We identified keywords, analysed these incontext and derived key themes.SettingPromotion through social media allowed respondents from any country to participate.ParticipantsPeople with CF and those close to them.ResultsResponses were received from 393 people, including 266 parents and 97 people with CF. The key themes were the emotional burden of PA (fear in particular); the burden of treatment PA entails and the need for accurate knowledge about PA.ConclusionsLack of knowledge and the health beliefs of individuals may promote fear of infection and inappropriate avoidance measures. Uncertainty about the implications of PA infection and the treatment required may cause anxiety. Healthcare professionals should provide clear information about how PA might be acquired and the treatment necessary, making clear the limitations of current understanding and acknowledging health beliefs.
Introduction: Cystic fibrosis is a life-limiting genetic condition characterized by recurrent pulmonary infection. Acquisition of infection can occur from environmental reservoirs, person-to-person transmission and from the healthcare environment. Primary prevention of infections through infection prevention and control measures is an important strategy in cystic fibrosis care. Areas covered: Here we present a systematic review of the evidence base around infection prevention and control in cystic fibrosis. We found 36 studies and 7 guidelines that met our inclusion criteria. Strategies covered include cohort segregation, individual segregation, hand hygiene, facemasks, combination strategies, equipment strategies, and adherence. Quality of evidence overall was deemed low or very low. Most guideline recommendations have little or no evidence to support them. Expert opinion: Although low quality, there is an abundance of evidence suggesting segregation is beneficial in reducing pathogen spread. Undertaking high-quality studies may, therefore, be ethically challenging. Large-scale registry studies may provide a better strategy for answering questions on the efficacy of infection control policy. With the rise of antibiotic resistance, effective eradication of cystic fibrosis pathogens is becoming more difficult so primary prevention through infection control will become increasingly important over the coming years.
