Efficacy of omalizumab in the treatment of nasal polyps

nine acute trusts in the UK. All hospitals (eight teaching hospitals and one district general hospital) had an acute NIV service and a local coordinating clinician was recruited through the BTS Respiratory Critical Care Specialist Advisory Group. Questionnaires and data collection guidelines were distributed by e-mail to the local lead who was responsible for distributing, collecting and marking the questionnaires. Three hundred and ninety-four completed questionnaires were returned and scored with weighting given towards clinical relevance and current evidence base. To generate comparative analysis the groups were compared with a 'control' group, which consisted of 119 medical consultants and trainees, nurses and physiotherapists working on general medical wards but not in critical care or specialist respiratory medicine. Respiratory and critical care physicians were combined for the purposes of data analysis as there was no difference between these groups.
