Under-reporting of asthma and inappropriate management at school can hamper a child's academic progress. The aim of this study was to assess asthma reporting and crisis management, following implementation of a Primary School Asthma Programme. The intervention covered 12 primary schools with 5093 students in an area of high unemployment with a large proportion of the community from a non-English background. The programme included School Asthma First Aid Kits, training workshops for school staff and individual Crisis Management Plans for students with asthma. Registration of students with asthma at school increased from 6.2% before the intervention in 1989 to 12.7% in 1992. School Asthma Crisis Plans were completed appropriately by the child's doctor and parents and returned by 68% of the students with asthma. Teachers' asthma knowledge and confidence with the management of acute asthma at school improved following asthma education workshops. It was concluded that asthma reporting and acute crisis management of asthma at school can be achieved by a programme undertaken by school medical services.
