Hemostatic agents can be used to reduce the risk of bleeding in cardiac device implantation (CDI). In October 2019, operators at our institution began to utilize Surgicel® hemostatic powder in patients with high bleeding risk. We also noted a concomitant rise in device infections. In January 2020, we discontinued Surgicel® use and infection rates returned to baseline. We conducted a retrospective case-control study to determine whether Surgicel® use was independently associated with an increased risk of CDI-related infection. We hypothesized that the use of Surgicel® was independently associated with risk of CDI-related infection. Patients undergoing implantation of pacemaker, internal cardioverter defibrillator (ICD), or cardiac resynchronization (CRT) devices were included for analysis. All CDI patients were prospectively surveilled for infection for a period of 90 days after implant. We reviewed all cardiac implants between July 1, 2019 and August 31, 2020. Surgicel® was utilized between October 2019 and January 2020. We recorded the following risk factors: age, sex, obesity (BMI >30), device type, steroid use, generator change, tobacco use, diabetes, chronic kidney disease, immunocompromised status (HIV+ or use of non-steroidal immunosupressive agent), Surgicel® use, antiplatlet agent use, anticoagulation, and post-operative hematoma. Multivariable analysis was performed using a logistic regression model including all factors that were significantly associated with infection by univariate analysis. During the study period a total of 512 patients underwent CDI with 11 confirmed infections (2.1%). 8/11 infections (73%) were associated with Surgicel® use. In multivariable analysis, factors independently associated with infection were: Surgicel® use (OR 26.15, 95% CI (4.44 - 154.100) p <0.0001), Obesity (OR 8.97 95% CI (1.45 - 55.65) p =0.018), Immunodeficiency (OR 114.32 95% CI (6.78 - 1928.26) p= 0.001), and hematoma (OR 5.51 95% CI (1.13 - 26.88) p = 0.035. Surgicel® use was strongly and independently associated with risk of CDI related infection. Other factors independently associated with increased infection risk include obesity, immunodeficiency, and hematoma.
