A Review of a Tertiary Referral Centre's CT Coronary Angiography Programme
Insights
Outpatient CT coronary angiogram (CTCA) waiting times did not significantly impact major adverse cardiovascular events (MACE) in stable chest pain patients. However, delays in prognostic treatment and administrative support needs were identified.
Area of Science:
- Cardiology
- Radiology
- Health Services Research
Background:
- Outpatient CT coronary angiogram (CTCA) is a key diagnostic tool for stable chest pain.
- Understanding the impact of waiting times on patient outcomes and service delivery is crucial for optimizing cardiac care pathways.
Purpose of the Study:
- To evaluate the association between outpatient CTCA waiting times and patient outcomes.
- To assess the implications for service provision within cardiology and emergency departments.
Main Methods:
- Retrospective analysis of 172 outpatient CTCAs for stable chest pain in 2017.
- Data collection included major adverse cardiovascular events (MACE), emergency department presentations, cardiology outpatient attendance, treatment alterations, and revascularization rates.
Main Results:
- A low rate of MACE (1 non-fatal MI) and revascularization (7 percutaneous coronary interventions) was observed.
- 12.2% of patients required prognostic treatment alteration, averaging 10.4 months post-CTCA.
- 22.1% attended outpatient clinics before scan completion, indicating potential administrative inefficiencies.
Conclusions:
- The low MACE rate suggests appropriate patient selection for CTCA in this cohort.
- Delays in treatment modification and pre-scan outpatient attendance highlight areas for improved administrative support and service coordination.
Abstract:
Aims To investigate the implication of outpatient CT coronary angiogram (CTCA) waiting times on patient outcomes and service provision. Methods All outpatient CTCAs requested for stable chest pain during 2017 in our catchment area were included. Rate of major adverse cardiovascular events (MACE), presentations with chest pain to the emergency department (ED), cardiology outpatient attendance, time interval in alteration of Coronary artery disease (CAD) prognostic treatment, rate of angiography and percutaneous coronary intervention (PCI) were noted. Results 172 CTCAs were included. 11 (6.4%) presented to ED with chest pain. 38 (22.1%) attended outpatients prior to scan completion. 17 (9.9%) required alteration of prognostic treatment, taking on average 10.4 (+/-4.5) months to occur. 21 (12.2%) underwent coronary angiography and 7 (4.1%) had PCI, which took on average 9.9 (+/-6.6) months. One non-fatal MI requiring CABG was noted. Conclusion The low rate of MACE and revascularisation likely represents appropriately low risk patient selection for CTCA. Presentation to clinic prior to scan completion highlights a need for better administration support.
