Sex differences in the pre-hospital ambulance delay, assessment and treatment of patients with acute coronary syndrome: a rapid evidence review.

BACKGROUND

Chest pain is a frequent symptom suffered by adult patients attended by ambulance. Evidence suggests female patients may suffer different symptoms to their male counterparts, potentiating differences in pre-hospital time delays, assessment and treatment.

OBJECTIVE

To explore the sex differences in the pre-hospital ambulance delay, assessment and treatment of patients with acute coronary syndrome (ACS).

METHODS

A rapid evidence review was conducted following the Cochrane rapid review guidelines. MEDLINE and CINAHL Complete were searched via EBSCOhost on 2 February 2023, and reference lists of included studies and reviews were screened. The Joanna Briggs Institute checklist for analytical cross-sectional studies was used to perform critical appraisal, and a narrative synthesis was conducted.

RESULTS

From 216 articles screened, nine were included, representing over 3.1 million patients from five different countries. Female patients were more likely to suffer delays in time to first electrocardiogram (ECG) and delays in transport time to the emergency department by ambulance. Female patients were also less likely to receive an ECG, aspirin, glyceryl trinitrate and other analgesics.

CONCLUSION

There are sex disparities in the pre-hospital ambulance delay, assessment and treatment of patients with ACS. Future research is urgently needed to fully understand the reasons for these observations.
