BACKGROUND: Frailty is a common characteristic of patients undergoing transcatheter mitral valve repair (TMVR). It is unclear whether the physical vulnerability of frail patients translates into increased procedural health care utilization.
METHODS AND RESULTS: Frailty was assessed using the Fried criteria in 229 patients undergoing TMVR using the MitraClip system at our institution and associations with total costs and costs by cost centers within the hospital incurred during periprocedural hospitalization were examined. Frail patients (n = 107, 47%) compared to non-frail patients showed significantly higher total costs [median/interquartile range, excluding implant costs: 7,337 € (5,911-9,814) vs 6,238 € (5,584-7,499), p = 0.001], with a difference in means of 2,317 €. Frailty was the only clinical baseline characteristic with significant association with total costs. Higher total costs in frail patients were attributable primarily to longer stay on intermediate/intensive care unit (3.8 ± 5.7 days in frail vs 2.1 ± 1.7 days in non-frail, p = 0.003), but also to costs of clinical chemistry and physiotherapy. The prolonged stay on intermediate/intensive care unit in frail patients was attributable to postprocedural complications such as bleeding, kidney injury, infections and cardiovascular instability.
CONCLUSION: Frailty is associated with a mean 32% increase of hospital costs in patients undergoing TMVR, which is primarily the result of a prolonged recovery and increased vulnerability to complications. These findings are valuable for a hospital's total cost calculation and resource allocation planning. Since frailty is regarded a potentially reversible health state, preventive interventions may help reduce costs in frail patients.
