Reduction of shunt dependency rates following aneurysmal subarachnoid hemorrhage by tandem fenestration of the lamina terminalis and membrane of Liliequist during microsurgical aneurysm repair.

OBJECTIVEShunt-dependent hydrocephalus is an important cause of morbidity following aneurysmal subarachnoid hemorrhage (aSAH) in excess of 20% of cases. Hydrocephalus leads to prolonged hospital and ICU stays, well as to repeated surgical interventions, readmissions, and complications associated with ventriculoperitoneal (VP) shunts, including shunt failure and infection. Whether variations in surgical technique at the time of aneurysm treatment may modify rates of shunt dependency remains a matter of debate. Here, the authors report on their experience with tandem fenestration of the lamina terminalis (LT) and membrane of Liliequist (MoL) at the time of open microsurgical repair of the ruptured aneurysm.METHODSThe authors conducted a retrospective review of 663 consecutive patients with aSAH treated from 2005 to 2015 by open microsurgery via a pterional or orbitozygomatic craniotomy by the senior author (M.T.L.). Data collected from review of the electronic medical record included age, Hunt and Hess grade, Fisher grade, need for an external ventricular drain, and opening pressure. Patients were stratified into those undergoing no fenestration and those undergoing tandem fenestration of the LT and MoL at the time of surgical repair. Outcome variables, including VP shunt placement and timing of shunt placement, were recorded and statistically analyzed.RESULTSIn total, shunt-dependent hydrocephalus was observed in 15.8% of patients undergoing open surgical repair following aSAH. Tandem microsurgical fenestration of the LT and MoL was associated with a statistically significant reduction in shunt dependency (17.9% vs 3.2%, p < 0.01). This effect was confirmed with multivariate analysis of collected variables (multivariate OR 0.09, 95% CI 0.03-0.30). Number-needed-to-treat analysis demonstrated that tandem fenestration was required in approximately 6.8 patients to prevent a single VP shunt placement. A statistically significant prolongation in days to VP shunt surgery was also observed in patients treated with tandem fenestration (26.6 ± 19.4 days vs 54.0 ± 36.5 days, p < 0.05).CONCLUSIONSTandem fenestration of the LT and MoL at the time of open microsurgical clipping and/or bypass to secure ruptured anterior and posterior circulation aneurysms is associated with reductions in shunt-dependent hydrocephalus following aSAH. Future prospective randomized multicenter studies are needed to confirm this result.

Validation of a Parent-Reported Experience Measure of Integrated Care.

OBJECTIVES: The objectives of this study were to design and validate a survey measuring the parents' and caregivers' experiences of integration of their child's care across providers. METHODS: After review of the literature on care coordination and integration, we solicited input regarding care experiences from focus groups of families with children with chronic conditions. These data informed a 95-item pilot survey that included elements from a care integration measure designed for adult care experiences. The survey was then administered to parents of children who had had at least 1 primary care appointment and 2 specialty care appointments in the previous 12 months. Psychometric analyses were used to establish scales through exploratory factor analysis, internal consistency using Cronbach's α, test-retest reliability using Spearman's rank correlation coefficient, and known-group validity according to χ2 tests. All research activities were institutional review board approved. RESULTS: The pilot survey was completed as either a Web or mail survey by 255 participants. After excluding nonrating or screening questions and items not applicable to a large percentage of participants, 26 experience items were included in the exploratory factor analysis. The final survey contained 19 experience items in 5 scales: access, communication, family impact, care goal creation, and team functioning. Psychometric analyses supported these 5 scales. CONCLUSIONS: This project developed and validated a survey with 19 experience items, plus additional demographic and health needs and usage items. The Pediatric Integrated Care Survey can be used in quality improvement efforts to measure family-reported experience of pediatric care integration.
