Spinal Cord Stimulator Implant Infection Rates and Risk Factors: A Multicenter Retrospective Study
Neuromodulation : journal of the International Neuromodulation Society, 2017
Spinal cord stimulation is an evidence-based treatment for a number of chronic pain conditions. While this therapy offers improvement in pain and function it is not without potential complications. These complications include device failure, migration, loss of therapeutic paresthesia, and infection. This article looked to establish a modern infection rate for spinal cord stimulators, assess the impact of known risk factors for surgical site infections and to determine the impact of certain preventative measures on the rate of infection. After institutional review board approval, a multisite, retrospective review was conducted on 2737 unique implants or revisions of SCS systems. Patient demographics, risk factors including diabetes, tobacco use, obesity, revision surgery, trial length, implant location, implant type, surgeon background, prophylactic antibiotic use, utilization of a occlusive dressing, and post-operative antibiotic use were recorded and analyzed. The overall infection...
Management and Outcome of Permanent Pacemaker and Implantable Cardioverter-Defibrillator Infections
Journal of The American College of Cardiology, 2007
We describe the management and outcome of permanent pacemaker (PPM) and implantable cardioverter-defibrillator (ICD) infections in a large cohort of patients seen at a tertiary care facility with expertise in device lead extraction.Infection is a serious complication of PPM and ICD implantation. Optimal care of patients with these cardiac device infections (CDI) is not well defined.A retrospective review of all patients with CDI admitted to Mayo Clinic Rochester between January 1, 1991, and December 31, 2003, was conducted. Demographic and clinical data were collected, and descriptive analysis was performed.A total of 189 patients met the criteria for CDI (138 PPM, 51 ICD). The median age of the patients was 71.2 years. Generator pocket infection (69%) and device-related endocarditis (23%) were the most common clinical presentations. Coagulase-negative staphylococci and Staphylococcus aureus, in 42% and 29% of cases, respectively, were the leading pathogens for CDI. Most patients (98%) underwent complete device removal. Duration of antibiotic therapy after device removal was based on clinical presentation and causative organism (median duration of 18 days for pocket infection vs. 28 days for endocarditis; 28 days for S. aureus infection vs. 14 days for coagulase-negative staphylococci infection [p < 0.001]). Median follow-up after hospital discharge was 175 days. Ninety-six percent of patients were cured with both complete device removal and antibiotic administration.Cure of CDI is achievable in the large majority of patients treated with an aggressive approach of combined antimicrobial treatment and complete device removal. Based on findings of our large retrospective institutional survey and previously published data, we submit proposed management guidelines of CDI.

Objectives: Chronic pain spinal implantable electronic devices (CPSIEDs) include devices that provide spinal cord stimulation and intrathecal drug therapy. In this study, we sought to evaluate the trends of CPSIED infections, related complications, and outcomes following the treatment of infection. Materials and Methods: The Nationwide Inpatient Sample database contains data from 48 states, and the District of Columbia was used to identify patients with a primary diagnosis of CPSIED infection during the years 2005-2014. Patients with intrathecal pumps for the treatment of spasticity were excluded to limit the study population to patients with chronic pain disorders. Treatments were categorized as: 1) without device removal, 2) pulse generator or pump only removal, 3) intrathecal pump system removal, and 4) spinal cord stimulation system removal. Complications associated with CPSIED infections were identified using administrative billing codes. Results: During the study period 2005-2014, a total of 11,041 patients were admitted to the hospital with CPSIED infections. The majority of the patients were treated without surgical intervention (56%), and a smaller proportion underwent complete system explantation (22.7%). In-hospital mortality or permanent disability due to paralysis after CPSIED infection was around 1.83% and 2.77%, respectively. Infectious complications such as meningitis, abscess formation, and osteomyelitis occurred in 4.93%, 5.08%, and 1.5%, respectively. The median cost of hospitalization was around US $14,118.00, and the median length of stay was approximately six days (interquartile range = 4-13 days). Conclusions: The complications of CPSIED infection were higher among patients that did not undergo device removal.

Surgical site infection is a potential complication of spinal cord stimulator (SCS) implantation. Current understanding of the epidemiology, diagnosis, and treatment of these infections is based largely on small clinical studies, many of which are outdated. Evidence-based guidelines for management of SCS-related infections thus rely instead on expert opinion, case reports, and case series. In this study, we aim to provide a large scale retrospective study of infection management techniques specifically for SCS implantation. A multicenter retrospective study of SCS implants performed over a seven-year period at 11 unique academic and non-academic institutions in the United States. All infections and related complications in this cohort were analyzed. Within our study of 2737 SCS implant procedures, we identified all procedures complicated by infection (2.45%). Localized incisional pain and wound erythema were the most common presenting signs. Laboratory studies were performed in the ...

Methods: The authors analyzed the incidence and risk factors for cardiac device infection (CDI) among consecutive patients implanted with pacemaker (PM) or implantable cardioverter defibrillator (ICD) (including cardiac resynchronization therapy devices) at a tertiary health center in Hamilton, Ontario, Canada. Most patients with device-related infections were identified by an internal infection control system that reports any positive wound and blood cultures following surgery, between 2005 and the present. A retrospective review of patient records was also performed for all patients who received an ICD or PM between Results: A total of 24 infections were identified among 2,417 patients having device surgery (1%). Fifteen of these infections (60%) were diagnosed within 90 days of the last surgical procedure. Univariate analysis showed that patients presenting with CDI were more likely to have had a device replacement, rather than a new implant, had more complex devices (dual/triple chamber vs single), and were more likely to have had a prior lead dislodgement. Multivariate analysis found device replacement (P = 0.02) and cardiac resynchronization therapy (CRT)/dual-chamber devices (P = 0.048) to be independent predictors of infection. One patient developed septic pulmonary emboli after having laser-assisted lead extraction. No patient died and 22 patients received a new device.

BackgroundIncreasing evidence-based indications for the implantation of permanent pacemakers (PMs) and implantable cardioverter defibrillators (ICDs) have led to an increase in the rate of device infections. The aim of the present study was to evaluate infection frequency, clinical characteristics, risk factors, and microbiologic and therapeutic features in patients with PM/ICD infections.Increasing evidence-based indications for the implantation of permanent pacemakers (PMs) and implantable cardioverter defibrillators (ICDs) have led to an increase in the rate of device infections.

The control group in this case-control study consisted of 833 patients in whom a PM or ICD had been implanted and no infections were noted.ResultsPatients with PM/ICD infections (median age 65 years; range, 18–104 years) were older than those without PM/ICD infections (median age 58 years; range, 18–86 years; P = 0.005). The percentage of generator replacement was higher in the PM/ICD infection group compared with the control group (16% vs 8%, P = 0.003). Independent predictors of PM/ICD infections were advanced age (>60 years; odds ratio [OR]: 2.5, 95% confidence interval [CI]: 1.2–4.0, P = 0.021) and device revision (OR: 3.8, 95% CI: 1.5–5.5, P = 0.002). Primary antibiotic prophylaxis during the procedure reduced the risk for PM/ICD infection (OR: 0.5, 95% CI: 0.4–0.8, P = 0.011).Patients with PM/ICD infections (median age 65 years; range, 18–104 years) were older than those without PM/ICD infections (median age 58 years; range, 18–86 years; P = 0.005).
