Our objective was to describe the design of Cardiac Link, a coronary computed tomography angiogram (CCTA)-guided rapid-access program, and evaluate its effect on cardiology consultation wait times in patients who present to primary care physicians with stable chest pain.Methods: We conducted a retrospective cohort study at Women’s College Hospital, Toronto, Ontario, Canada, between 2017 and 2020 involving eligible patients from the Family Practice Health Centre who underwent CCTA after presenting with stable chest pain or equivalent symptoms. Referring primary care physicians decided on a patient-by-patient basis to opt into the Cardiac Link program when requesting CCTA. Our primary outcome was measure of time from CCTA to cardiology consultation, and our secondary outcomes were measures of time to diagnosis from primary care consultation and CCTA booking time.Results: Our analysis included 148 patients (Cardiac Link n = 98, non–Cardiac Link n = 50). Mean age of the patients was 58.4 (SD 11.2) years and 72% (107/148) were women. We found that the Cardiac Link group had a shorter time from CCTA to cardiology consultation (median 7 [interquartile range {IQR} 6–20] d v. median 100 [IQR 40–138] d; p = 0.01), shorter time to diagnosis (median 33 [IQR 22–55] d v. median 86 [IQR 40–112] d; p < 0.001) and shorter CCTA booking time (median 18 [IQR 11–31] d v. median 65 [IQR 24–92] d; p < 0.001) compared with the non–Cardiac Link group.Interpretation: We determined that the Cardiac Link program reduced cardiology consultation wait times for symptomatic patients who were suspected of having CAD. Our study shows the viability of CCTA-guided rapid-access programs to expedite specialist consultation and reduce unnecessary referral for patients presenting to primary care physicians with stable chest pain.
