Performance assessment of a chest pain unit: Preliminary 2-year experience in the European Georges Pompidou Hospital.

BACKGROUND

Chest pain units (CPUs) are very popular in the USA for the triage of low-to-intermediate-risk chest pains. However, CPUs do not yet exist in France.

AIMS

To determine the prevalence and clinical characteristics of patients admitted to a new CPU in France, and to assess the quality of care with regard to identification and exclusion of an acute coronary syndromes (ACS).

METHODS

This prospective study included 906 consecutive patients with non-traumatic chest pain admitted to our CPU between September 2006 and August 2008. Patients were managed according to their probability of presenting with an ACS. Clinical characteristics, diagnostic tests, final diagnosis, destination and length of stay were recorded. We also assessed the 30-day outcome of patients in whom an ACS was excluded.

RESULTS

Of the 906 patients, 27.9% had an ACS (1.3% with and 26.6% without ST-segment elevation, respectively). Non-ischaemic cardiac aetiologies and non-cardiac aetiologies were found in 123 (12.6%) and 63 (7.0%) patients, respectively. A final diagnosis of chest pain of undetermined origin was made in 51.5% of patients; among these, 17 (6.5%) patients were re-admitted to the CPU between September 2006 and September 2007. Thirty-day follow-up revealed that only one patient had subsequent confirmation of coronary artery disease requiring further hospitalization.

CONCLUSIONS

This prospective study reports the first experience of a CPU in a cardiology department in France. Our preliminary results suggest that our CPU can exclude an ACS safely. Further studies are warranted to assess the value of CPUs in France.
