Review question
C3 Are prophylactic treatments (for example, antibiotics, chest physiotherapy, cough assistance) effective in preventing respiratory infections in adults with cerebral palsy?
Introduction
Prophylactic or preventative treatments such as posture management, respiratory physiotherapy, cough assist devices, non-invasive ventilation; as well as background medications for gastro-oesophageal reflux, mucolytics and antibiotics can be used to prevent respiratory infections. This question looks at the evidence and cost-effectiveness of these interventions in adults with cerebral palsy.

Methods and process
This evidence review was developed using the methods and process described in Developing NICE guidelines: the manual 2014. Methods specific to this review question are described in the review protocol in appendix A and for a full description of the methods see supplementary document C.
Declaration of interests were recorded according to NICE’s 2014 conflicts of interest policy from May 2016 until April 2018. From April 2018 onwards they were recorded according to NICE’s 2018 conflicts of interest policy. Those interests declared until April 2018 were reclassified according to NICE’s 2018 conflicts of interest policy (see Interests Register).
Clinical evidence
Included studies
A systematic review of the clinical literature was conducted, but no relevant studies were identified which were applicable to this review question.

Excluded studies
Studies not included in this review with reasons for their exclusions are provided in Appendix K
Summary of clinical studies included in the evidence review
No clinical studies were identified for this review.
Quality assessment of clinical studies included in the evidence review
No clinical studies were identified for this review.
Economic evidence
Included studies
A systematic review of the economic literature was conducted, but no studies were identified which were applicable to this review question.
Excluded studies
No studies were identified which were applicable to this review question.
Summary of studies included in the economic evidence review
No economic evaluations were included in this review.
Economic model
This question was not prioritised for economic modelling as the committee considered that it was unlikely that any recommendation made would place significant additional costs on NHS or PSS budgets.
Resource impact
No unit costs were presented to the committee as these were not prioritised for decision making purposes.

The committee’s discussion of the evidence
Interpreting the evidence
The outcomes that matter most
Since this question was about prevention of respiratory infections, respiratory infections, hospital admissions and overall survival were the critical outcomes. Other outcomes considered important by the committee were health related quality of life and satisfaction.
The quality of the evidence
No evidence was identified for this review.
Benefits and harms
The committee discussed the government recommendations in the Green book vaccinations. For example it is recommended that people with pre-existing conditions, such as neurological conditions (which would include cerebral palsy) should be offered a flu vaccination. The committee therefore made a strong recommendation that the immunisation programme should be followed to prevent adults with cerebral palsy getting infections that could affect respiratory functions.
Based on their clinical experience and expertise, the committee discussed that prophylactic antibiotics are not helpful in preventing respiratory infections in adults with cerebral palsy. They may also lead to gastrointestinal and cardiac side effects. The committee agreed that the role of antibiotics is limited for prophylaxis of respiratory infections in adults with cerebral palsy. Taking into account potential adverse effects and the antibiotic resistance, the committee agreed that antibiotic prophylaxis should only be used in people at high risk of infection when it is advised by the respiratory specialist. For example, this might be in people with recurrent chest infections and bacterial colonisation identified on sputum culture. The aim in these cases would be to reduce acute antibiotic use and limit symptom burden.
The committee discussed, based on their experience and expertise, that a chest physiotherapy review, including postural management and exercise will be helpful in preventing respiratory infections, in those at high risk. The committee noted that physiotherapists would usually have chest care training which would provide them with the skills to be able to carry out an assessment and suggest treatments. The committee also noted that the effective implementation of these measures will require families and carers to have understanding regarding training and care. Hence, they must be advised on these aspects.
Based on their expertise and experience, the committee agreed that saliva management will benefit in preventing respiratory infections. The committee discussed that adults with cerebral palsy and recurrent chest infections should be referred to a dysphagia-trained speech and language therapist who would be best suited to assess swallowing and saliva control in those with respiratory difficulties. Timely assessment will then help to put into place preventative action against respiratory infections.
Due to the lack of evidence the committee decided to make a research recommendation on the effectiveness of prophylactic antibiotic in the management of respiratory symptoms. The committee agreed that this is important because some individuals with cerebral palsy experience significant respiratory symptomatology as a consequence either of sputum retention and or recurrent respiratory infection, possibly related to aspiration. A smaller proportion of individuals experience chronic pulmonary bacterial colonisation with increased respiratory symptom burden and recurrent infective episodes. No current high quality evidence exists to determine the effectiveness of prophylactic antibiotics in the management of such patients. Research is recommended to establish the role of prophylactic antibiotics in those with, and without, persistent bacterial airway colonisation with a view to improving quality of life, patient experience and hospital stay.
Cost effectiveness and resource use
The committee noted that no relevant published economic evaluations had been identified for this topic.
The recommendation around flu and pneumococcal vaccination reinforces current best practise and is unlikely to have any impact upon resource use.
The recommendations on prophylactic antibiotic use again reinforces best practice. The committee considered that there may be centres in England where antibiotics are given unnecessarily and that the recommendations would lead to a reduction in their use and cost savings.
There will be an increase in resource use, through increased referrals, associated with the recommendations for referral to chest physiotherapy and speech and language therapists although the committee considered that this was likely to be small. Improved outcomes would also likely lead to a reduction in expensive unplanned admissions to hospital.
