Abstract/summary background: indications for deep brain stimulation (dbs) are rapidly growing within functional neurosurgery.The objective of this study was to characterize national trends in demographics and complications across distinct populations of dbs patients.Methods: we identified patients from the 2008¿2018 american college of surgeons national surgical quality improvement program (acs nsqip) participant use data file (puf) who underwent an implantation or revision procedure for dbs.Summary statistics for postoperative infection rate, noninfectious complication rate, total hospital length of stay, discharge disposition, mortality, reoperation or readmission, and time from operation to readmission were obtained.Patients were categorized by diagnosis for dbs treatment.Outcomes for each diagnosis group were compared to outcomes for the total study population.Results: dbs patients who underwent primary implantation procedures had low rates of postoperative infections (1.2%), noninfectious complications (0.8%), and mortality (0.1%) and a high likelihood of discharge home (97.6%).In addition, a large percentage of patients presented for revision or removal of neurostimulators (34.2% of cases) or treatment of long-term hardware infection (4.5%).Compared with patients with other diagnoses, patients with parkinson disease experienced lower rates of noninfectious complications (odds ratio 0.32; 95% ci, 0.15¿0.63; p = 0.002) and fewer unplanned reoperations (odds ratio 0.60; 95% ci, 0.39¿0.92; p = 0.02).Conclusion: analysis of a national database suggests that dbs is a relatively safe treatment across several different patient populations.These overall favorable results support the continued practice of dbs surgery and provide encouraging validation for increasing access to dbs therapy for new indications that are being actively investigated.Reported events: less than eight patients with dbs implanted for other diagnosis experienced postoperative infection, which included sepsis, deep surgical site infection, superficial surgical site infection, and organ space surgical site infection.Five patients with dbs implanted for other diagnosis experienced noninfectious complications, which included stroke and wound disruption.Less than 11 patients with dbs implanted for other diagnosis experienced unplanned reoperation.Less than 8 patients with dbs implanted for other diagnosis experienced readmission within 30 days.Information regarding patient complications, readmission subcategories, and reoperations beyond 30 days after the procedure was not available.
