Data analysis
All data were analysed using Microsoft Access and Excel by the staff at NCEPOD. Quantitative analysis of the data from all questionnaires was performed along with further qualitative analysis following review of the casenotes of the deceased patients by an advisory group. Where tables indicate ‘not answered’ this means that no information was provided for this particular analysis. Where ‘insufficient data’ is indicated this means that the advisors could not make a decision based on the information available. Where ‘unknown’ is shown in tables this is the box ticked by the hospital clinician completing the questionnaire.
