Objectives: This study aimed to estimate the incidence of medical consultations six months after an emergency department (ED) consultation for non-cardiac chest pain (NCCP). It also investigated the role of heart-focused anxiety (HFA) and other factors in predicting an increased healthcare utilization in these patients.
Method: This was a prospective study of 428 patients who came to an ED with NCCP. Patients completed an interview and questionnaires assessing HFA, psychological distress, the characteristics of NCCP, and comorbidities. Their medical consultations were assessed by telephone interview six months later. The contribution of each factor was assessed using a binomial negative regression.
Results: Eighty-three percent of patients reported at least one medical consultation (mean=3.1, standard deviation=3.9). HFA (incident rate ratio 1.01; 95% CI, 1.00-1.02), the presence of a medical condition (2.14; 1.51-3.03), NCCP frequency (1.49; 1.16-1.91) and NCCP-related interference (1.08; 1.04-1.13) were predictive of further medical consultations.
Conclusions: A significant proportion of patients with NCCP are at risk of multiple medical consultations following discharge from the ED. HFA appears as a determinant of medical consultations after controlling for multiple confounding factors.
