Cross-Sectional Analysis of US Health Insurance Payer Policies for Humanitarian Device Exemption Indications for Deep Brain Stimulation.

BACKGROUND: The US Food and Drug Administration (FDA) has granted deep brain stimulation (DBS) approval under the humanitarian device exemption (HDE) pathway for both dystonia and obsessive-compulsive disorder (OCD). However, recent reports from the community of functional neurosurgeons suggest that insurance authorization remains a disproportionate barrier to OCD DBS implantation despite both conditions having similar support from the FDA. This cross-sectional study of health insurance policies quantifies the current payer landscape for these two interventions. OBJECTIVES: The aim of this study was to quantify the current payer policy coverage of DBS under HDE status for OCD as compared to DBS for dystonia for eligible patients in the US insurance market. METHODS: A commercial health insurance policy database was queried for documentation on DBS for dystonia and OCD. Results were individually analyzed for payer policy coverage statements on DBS for either dystonia or OCD and categorized as unique or nonunique policies. Unique policy positions were then coded for the geographic region, whether coverage was offered, and guidelines cited as evidence and justification. RESULTS: From the 80 policies in the database, there were 34 unique policies addressing DBS for either dystonia or OCD representing coverage of all 50 states. Of the 34 unique policies, 3 (9%) covered DBS for OCD, while 32 (94%) covered dystonia. Only 2 policies covered neither intervention. CONCLUSIONS: In spite of similar levels of support from the FDA, DBS for OCD has less support from insurance companies on a national level. This study begins to quantify the disparity noted by functional neurosurgeons in recent literature.

Doing More with Less: A Minimally Invasive, Cost-Conscious Approach to Stereoelectroencephalography.

BACKGROUND: Stereoelectroencephalography (SEEG) is a commonly used technique for mapping the epileptogenic zone before epilepsy surgery. Many SEEG depth electrode implantation techniques involve the use of extensive technological equipment and shaving of the patient's entire head before electrode implantation. Our goal was to evaluate an SEEG depth electrode implantation technique that used readily available cost-effective neurosurgical equipment, was minimally invasive in nature, and required negligible hair shaving. METHODS: Data on demographic characteristics, operative time, hemorrhagic complications, implantation complications, infection, morbidity, and mortality among patients who underwent this procedure were reviewed retrospectively. RESULTS: Between April 2016 and March 2018, 23 patients underwent implantation of 213 depth electrodes with use of this technique. Mean (SD) operative time was 123 (32) minutes (range, 66-181 minutes). A mean (SD) of 9.3 (1.4) electrodes were placed for each patient (range, 8-13 electrodes). Two of the 213 electrodes (0.9%) were associated with postimplantation asymptomatic hemorrhage. One of the 213 electrodes (0.5%) was placed extradurally or incorrectly. None of the 213 electrodes was associated with symptomatic complications. No patients experienced infectious complications at any point in the preoperative, perioperative, or postoperative stages. CONCLUSIONS: This minimally invasive, cost-effective technique for SEEG depth electrode implantation is a safe, efficient method that uses readily available basic neurosurgical equipment. This technique may be useful in neurosurgery centers with more limited resources. This study suggests that leaving the patient's hair largely intact throughout the procedure does not pose an additional infection risk.

Laparoscopic-Assisted Ventriculoperitoneal Shunt Placement and Reduction in Operative Time and Total Hospital Charges.

OBJECTIVE: In ventriculoperitoneal shunt (VPS) placement, distal placement of the peritoneal catheter will typically be performed by a neurosurgeon. More recently, laparoscopic-assisted (LA) placement of the distal peritoneal catheter by general surgeons has become common. The present study examined whether LA placement of a VPS (LAVPS) is associated with a reduced operative time, lower hospital costs, and fewer distal revisions. METHODS: A retrospective review was performed of the data from all patients who had received a new VPS at our institution from 2013 to 2016. Age, sex, diagnosis, previous abdominal surgery, operative time, anesthesia grade, incidence of 30-day shunt failure, and total hospital charges were analyzed. RESULTS: A total of 680 patients had undergone first-time VPS placement, including 199 with LAVPS and 481 with non-LAVPS placement (non-LAVPS). The mean age of the LAVPS patients was significantly older than that of the non-LAVPS patients (64.1 vs. 59.3 years; P = 0.002). The mean operative time was shorter in the LAVPS group than in the non-LAVPS group (55 vs. 75 minutes; P < 0.001). Distal shunt revision within 30 days occurred more often for the non-LAVPS patients (6 of 481 [1.2%]) than for the LAVPS patients (0 of 199 [0%]). A subset analysis of patients with normal-pressure hydrocephalus found decreased total hospital charges in the LAVPS group ($67,124 vs. $80,890; P = 0.009). CONCLUSIONS: Compared with non-LAVPS, LAVPS was associated with significantly shorter operative times and fewer distal shunt revisions within 30 days. The findings from a subset analysis supported a decrease in total hospital charges. Additional studies are needed; however, these data suggest that LAVPS is a safer, less-expensive alternative to non-LAVPS.
