- WHAT WE FOUND:Length of stay and time to surgery were significantly reduced after implementation of this admission pathway. Readmission rate was not adversely affected by this change. The protocol also significantly reduced the number of unnecessary body computed tomography imaging studies obtained in this patient population.CONFOUNDING FACTORS/REAL-LIFE IMPLICATIONS:The results of this study should be interpreted with their retrospective nature in mind. Further, analysis of this admission pathway did not take into consideration patient perspective or cost implications. Finally, the authors recognize that the resources for such an operational shift may only be found in large, tertiary, referral centers.Optimized specialized care for patients with new single brain masses promotes improved health care outcomes. It may also predictively reduce health care costs and improve patient satisfaction. More research is needed in this field. Limitations to our study included the inherent limitations of a retrospective pre-post design that can make it difficult to separate the effect of a specific intervention from other factors that change over time. In addition, assessment of patient satisfaction, use of diagnostic tests beyond body imaging, and advanced cost analysis could have strengthened this study. Lastly, it should be noted that the applicability of our approach may be limited to major tertiary centers with enough resources to implement such a pathway.Purpose:To reduce care variation and improve the management of patients with newly identified single brain masses and no history of cancer, we implemented a dedicated admission protocol.Methods:We reviewed records of 206 patients who presented to our emergency department between January 2010 and May 2016 with a new single brain mass but no history of cancer. Patients admitted before the protocol implementation were designated the pre-implementation group (PRE), and those admitted after implementation were designated the post-implementation group (POST).Results:Ninety-six patients were in the PRE group and 110 in the POST group. Length of stay for POST patients was significantly shorter than for PRE patients (6 v 7 days, respectively; P = .042), and this effect was more robust after excluding the 66 patients who were discharged to rehabilitation, skilled nursing, or hospice facilities (5 v 7 days, respectively; P = .001). Additional comparison of POST with PRE patients showed that time to surgery was significantly reduced (2.7 v 3.5 days, respectively; P = .006) and that computed tomography scans of the chest, abdomen, and pelvis were reduced (12% v 47%, respectively; P < .001). No difference was found in the 30-day readmission rates. For patients with GBM, there also was no significant difference in time to initiation of chemoradiation or in median overall survival.Conclusion:Implementation of a specialized admission pathway for patients with a new single brain mass decreased average length of hospital stay and time to surgery and reduced unnecessary diagnostic imaging tests in patients with primary brain tumors.

- Introduction: Our goal was to assess whether use of a standardized clinical protocol improves efficiency for patients who present to the emergency department (ED) with symptoms of transient ischemic attack (TIA).Methods: We performed a structured, retrospective, cohort study at a large, urban, tertiary care academic center. In July 2012 this hospital implemented a standardized protocol for patients with suspected TIA. The protocol selected high-risk patients for admission and low/intermediate-risk patients to an ED observation unit for workup. Recommended workup included brain imaging, vascular imaging, cardiac monitoring, and observation. Patients were included if clinical providers determined the need for workup for TIA. We included consecutive patients presenting during a six-month period prior to protocol implementation, and those presenting between 6-12 months after implementation. Outcomes included ED length of stay (LOS), hospital LOS, use of neuroimaging, and 90-day risk of stroke or TIA.Results: From 01/2012 to 06/2012, 130 patients were evaluated for TIA symptoms in the ED, and from 01/2013 to 06/2013, 150 patients. The final diagnosis was TIA or stroke in 45% before vs. 41% after (p=0.18). Following the intervention, the inpatient admission rate decreased from 62% to 24% (p<0.001), median ED LOS decreased by 1.2 hours (5.7 to 4.9 hours, p=0.027), and median total hospital LOS from 29.4 hours to 23.1 hours (p=0.019). The proportion of patients receiving head computed tomography (CT) went from 68% to 58% (p=0.087); brain magnetic resonance (MR) imaging from 83% to 88%, (p=0.44) neck CT angiography from 32% to 22% (p=0.039); and neck MR angiography from 61% to 72% (p=0.046). Ninety-day stroke or recurrent TIA among those with final diagnosis of TIA was 3% for both periods.Conclusion: Implementation of a TIA protocol significantly reduced ED LOS and total hospital LOS.

- Rationale: Oxygen is essential for cellular energy metabolism. Neurons are particularly vulnerable to hypoxia. Increasing oxygen supply shortly after stroke onset could preserve the ischemic penumbra until revascularization occurs.Aims: PROOF investigates the use of normobaric oxygen (NBO) therapy within 6 h of symptom onset/notice for brain-protective bridging until endovascular revascularization of acute intracranial anterior-circulation occlusion.Methods and design: Randomized (1:1), standard treatment-controlled, open-label, blinded endpoint, multicenter adaptive phase IIb trial.Study outcomes: Primary outcome is ischemic core growth (mL) from baseline to 24 h (intention-to-treat analysis). Secondary efficacy outcomes include change in NIHSS from baseline to 24 h, mRS at 90 days, cognitive and emotional function, and quality of life. Safety outcomes include mortality, intracranial hemorrhage, and respiratory failure. Exploratory analyses of imaging and blood biomarkers will be conducted.Sample size: Using an adaptive design with interim analysis at 80 patients per arm, up to 456 participants (228 per arm) would be needed for 80% power (one-sided alpha 0.05) to detect a mean reduction of ischemic core growth by 6.68 mL, assuming 21.4 mL standard deviation.Discussion: By enrolling endovascular thrombectomy candidates in an early time window, the trial replicates insights from preclinical studies in which NBO showed beneficial effects, namely early initiation of near 100% inspired oxygen during short temporary ischemia. Primary outcome assessment at 24 h on follow-up imaging reduces variability due to withdrawal of care and early clinical confounders such as delayed extubation and aspiration pneumonia.
