OBJECTIVES: In the US, nearly 400,000 Coronary Artery Bypass Graft (CABG) surgeries are performed yearly. Sternal wound infections (SWI) developed after CABG are burdensome to both patients and health systems. Single-patient use electrocardiogram (SPU-ECG) cable and lead systems reduce the risk of cross-contamination, helping reduce this burden. This study assessed the budget impact of implementing SPU-ECG compared to reusable cables and leads for CABG patients in the USA.
METHODS: A budget impact analysis was performed based on a published Markov model simulating the CABG patient journey. A cohort of patients was modelled to move between states, across settings (ICU/general ward/home), mechanical ventilation status (Yes/No), infection status (none/superficial SWI/deep SWI) and death. For the base case analysis, cost of care for 400,000 CABG patients over a year was estimated using the latest available literature data, adjusted to 2023 USD. Additional length of stay (LOS), readmissions, and costs were considered as indicators for SWI-related burden.
RESULTS: The patient population had mean age of 65 years and was 25.1% female. The model estimated that using SPU-ECG would reduce the total cost of care by USD299,230,128 (95%CI USD167,820,359 - USD464,887,953) for 400,000 patients, corresponding to USD748 per patient. The annual savings were driven by fewer SWIs, resulting in reduced LOS and fewer readmissions. The results were most sensitive to additional days due to deep SWI, costs of general ward and readmission rates of deep SWI.
CONCLUSIONS: This budget impact analysis suggests that the use of single-patient use electrocardiogram in the US would result in cost-savings by reducing the burden of sternal wound infections related to CABG surgery.
