Hospitalization-related economic impact of patients with cardiogenic shock in a high-complexity reference centre

Abstract

Aims: Cardiogenic shock (CS) is associated with high mortality. Current guidelines strongly recommend centralizing the care of these patients in high-complexity centres. We described the hospitalization-related economic cost and its main determinants in patients with CS in a high-complexity reference centre. Methods and results: This is a single-centre, retrospective study. All patients with CS (2015-17) were included. Hospitalization-related cost per patient was calculated by analytical accountability method, including hospital stay-related expenditures, interventions, and consumption of devices. Expenditure was expressed in 2018 euros. All-cause mortality during follow-up was registered. Ratio of cost per life-year gained (LYG) was also calculated. A total of 230 patients were included, with mean age of 63 years. In-hospital mortality was 88/230 (38.3%). Hospital stay was longer in patients surviving after the admission (21.7 vs. 7.5 days, P < 0.001). Total economic cost for the overall cohort was 3 947 118 (mean/patient 17 161). Most of this cost was attributable to hospital stay (81.1%). The rest of the expenditure was due to in-hospital procedures (13.1%) and the use of devices (5.8%). Most of hospital stay-related costs (79.8%) were due to Critical Care Unit stay. Mean follow-up was 651 days. Total LYG was 409.77 years for the whole series. The observed ratio of cost per LYG was 9632.52/LYG. Conclusions: Management of CS in a reference centre is associated to a significant economic cost, but with a low ratio of cost per LYG. Most of this cost is attributable to hospital stay, specifically in critical care units.
