Abstract
BACKGROUND: Septic shock therapies that shorten the time to physiologic and clinical recovery may result in financial savings. However, the financial implications of improving these nonmortal outcomes are not well characterized. Therefore, we quantified hospital charges associated with four outcomes: ICU length of stay, duration of invasive mechanical ventilation, duration of vasopressor use, and new renal replacement therapy. METHODS: This was an observational study using administrative data from a large academic hospital in the United States. The analysis included adults treated with vasopressors for septic shock in a medical ICU. Linear regression modeling with ordinary least square was used to estimate the incremental hospital charges associated with 1 day of ICU length of stay, 1 day of mechanical ventilation, 1 day of vasopressor use, and new renal replacement therapy. RESULTS: The study population included 587 adults with septic shock, including 180 (30.7%) who died in the hospital. The median charge for a septic shock hospitalization was $98,583 (interquartile range [IQR], $61,177-$136,672). Decreases in ICU length of stay, mechanical ventilation duration, and vasopressor duration of 1 day were associated with charge reductions of $15,670 (IQR, $15,023-$16,317), $15,284 (IQR, $13,566-$17,002), and $17,947 (IQR, $16,344-$19,549), respectively. Avoidance of new renal replacement therapy was associated with a charge reduction of $36,051 (IQR, $22,353-$49,750). CONCLUSIONS: Septic shock therapies that reduce the duration of organ support and ICU care have the potential to lead to substantial financial savings.
