Retrospective Study of Patients with Acute Presentation for Asthma to an Emergency Department in UK (RAPAE)

• How many previous admissions in past one year (12 months)
• How many presentations to A+E in previous one year (12 months)
• Diagnosis not confirmed therefore not on any ICS
• Poor compliance (less than 75% of ICS and/or LABA and/or LAMA and/or leukotriene prescriptions picked up in past year)
• Recent presentation and maintenance therapy not increased (primary care or secondary care issue)
• Is patient overweight BMI
• Is patient on hormonal therapy, OCP, HRT, male hormones
• Social class quintile from post code of address using ONS calculator
• Ethnically diverse (see appendix)
• First Eosinophil count on index admission
• Highest eosinophil count in past (ever) and date
• Treatment for diabetes type 2
• Treatment for diabetes type 1
• Treatment for hypertension
• Smoker ever (pack year) when gave up__________

After obtaining this information study team will use simple statistical methods such as frequency and associations with confidence intervals to investigate which factors are associated with frequency of presentation to A+E. They will ascertain the frequency of patients who are on maximum therapy and may benefit from biological therapy, especially if they have raised eosinophils in the past year.
