Oxygen use for chest pain in coronary care units across the UK.
OBJECTIVE
To quantify the adherence to national guidance for the use of oxygen in patients presenting with chest pain to coronary care units (CCUs) across the UK.


METHODS
Prospective survey.


METHODS
A total of 307 hospitals were contacted by telephone between August 2010 and October 2010. Of these, 48 had no CCUs, 10 units refused to take part and 18 hospitals were contacted on 2 occasions but were unable to provide the information due to paucity of time owing to heavy clinical workload. Overall 231 hospitals participated in the audit questionnaire.


RESULTS
A total of 30% of the units used oxygen titrated to saturations in accordance with national guidelines. There was no difference between units that had on-site availability of percutaneous coronary intervention and those that did not. Those hospitals where there was a policy for routine oxygen prescription were as unlikely to comply with the guidelines on oxygen use as hospitals where oxygen was not routinely prescribed.


CONCLUSIONS
Only one-third of CCUs in the UK reported adherence to guidelines with regards to oxygen delivery in patients presenting with chest pain. Despite this figure seeming rather low, this is consistent with practice through a range of specialties and guidelines. The evidence base for the oxygen guidance remains insecure. Additional research is required but in the meantime we recommend oxygen is prescribed according to current guidelines.
