We wish to comment on some of the strategies suggested by Norris
et al to reduce mortality from acute coronary attacks.1 Recently we reviewed outcomes for all cardiac arrests in adults presenting to the emergency department at the Norfolk and Norwich Hospital during 1991 and 1996. The region served by this hospital is
semirural, with a single tier response ambulance service. Between 1991 and 1996 several changes were made to the organisation and delivery of prehospital care. Foremost was the amalgamation of the
three ambulance services covering East Anglia. The proportion of calls
answered by a paramedic crew also changed, increasing from 70% to
100%. Ninety five per cent of calls were answered within 16 minutes in
1991 and within 22 minutes in 1996. Despite these changes there was no
significant difference in outcome. Fifteen out of 113 victims survived
to discharge in 1991 compared with 11 out of 147 in 1996.
