Invasive cardiac catheterization laboratories perform a variety of cardiac diagnostic and interventional procedures each year. With nationwide efforts to improve efficiency, room utilization and patient scheduling, little data is available regarding median procedure times.
For the years 2012-2014, all invasive cardiac procedures (excluding electrophysiology procedures, acute ST elevation myocardial infarction procedures, valvular interventions and peripheral interventions) at Duke University Medical Center were grouped into case type and analyzed based on mean case length and provider.
During the 3-year period, a total of 10,355 cases were analyzed. Fifteen staff cardiologists performed invasive procedures in the Duke Adult Cardiac Catheterization Laboratory during the study period. Case length was defined as “wheels in to wheels out” or the amount of time the patient was in the catheterization laboratory. The case counts, case type, % of overall cases, and mean case length were recorded and results are reported in the Table. Based on mean case length, a recommendation for scheduling (time slot in minutes) is provided.
Measurement and reporting of mean case length can be used to help determine workload and improve efficiency in cardiac catheterization laboratories. Use of mean case length to more effectively schedule patients may lead to reductions in waiting times. Future investigation should include targeted scheduling and interventions to improve catheterization laboratory efficiency and patient satisfaction.
|Procedure Type||Case Count||% of Overall Cases||Mean Case Length (min)||Recommended Scheduling Time Slot (min)|
|Left Heart Cath (including Coronary Angiography)||3,195||30.9%||93||90|
|Right Heart Cath + Left Heart Cath (including Coronary Angiography)||2,732||26.3%||89||90|
|Right Heart Cath Only||2,369||22.9%||59||60|
|Coronary Angiography + PCI||2,059||19.9%||112||120|
