Perioperative outcomes and hospital costs associated with flowable gelatin hemostatic matrix for lumbar surgeries in real world hospital setting

AbstractBackground: Efficient hemostasis during lumbar surgery (LS) is associated with better perioperative outcomes. Flowable gelatin hemostatic matrix (FGHM) is a new type of absorbable hemostatic agent, which is effective to control bleeding during spinal surgery. This study aimed to assess the impact of FGHM on perioperative outcomes and hospital costs associated with LS.Methods: This study retrospectively analyzed medical and billing records of patients who underwent LS for spinal degenerative disease in a Chinese tertiary care hospital from 2014 to 2016. The identified patients were further stratified into a FGHM group (n = 108) (using the combination of FGHM and gelatin sponge) and a historical control group (using oxidized cellulose and/or collagen, n = 82) for the adjusted comparisons of the perioperative outcomes using a propensity score matching method. Multiple generalized linear regression was conducted to assess the impact of using FGHM on total hospitalization costs.Results: Comparisons of ...
