Background: The pre-hospital delay to seek care remains the most significant barrier for effective management of acute myocardial infarction. Many of the previous studies mainly took place in Western countries. Few data are available about the care-seeking behavior of Hong Kong Chinese. Aim: The purpose of this study was to identify the predictors of pre-hospital delay in care seeking among Hong Kong Chinese patients with acute myocardial infarction. Methods: Adult Chinese patients ( n=301) with a confirmed diagnosis of acute myocardial infarction were recruited from the cardiac units of three regional hospitals in Hong Kong. Various socio-demographic, clinical, symptom presentation characteristics and patient perceptual factors were considered as potential predictors. Multivariate analysis was conducted to identify the independent predictors with pre-hospital delay in care-seeking among acute myocardial infarction patients. Results: Perceived barriers to care seeking constituted the most significant predictor for longer pre-hospital delay in acute myocardial infarction patients. Female gender was also significant in predicting longer delay, whereas a greater extent of symptom congruence and a greater extent of typical symptom presentation were significantly associated with a shorter delay. The final model accounted for 49.6% of the variance in pre-hospital delay as a whole. Conclusion: The most prominent predictors of pre-hospital delay are modifiable in nature, including the perceived barriers to care seeking and symptom congruence. Other sociodemographic and clinical factors also influence patients’ decision. Although these are non-modifiable, our findings provide important insight for educating high-risk individuals.
