The CLABSI Playbook: Design and Implementation of a Multipronged Approach to Decrease CLABSIs.

ABSTRACT: Central line-associated blood stream infections (CLABSIs) are a quality marker for the critical care environment. They have become an area of particular interest because they cost the healthcare system close to a billion dollars per year and have a significant impact on patient safety. Through a preliminary analysis of our system's CLABSI rates, we found significantly higher rates than the national average, prompting further investigation. We decreased our CLABSI rate by over 40% from 2021 (1.6 per 1,000 line days) to the fourth quarter of 2022 (0.91) and kept the rate below or around the national rate (0.86) for the last three quarters of 2022. Through looking at current outcome data, identifying key stakeholders, developing dedicated committees, conducting root cause analyses, monitoring progress, adjusting procedures, scaling to the system, and continuously monitoring and reporting results, we have shown the efficacy of this kind of quality improvement structure and strive to reduce our hospital system's impact on avoidable healthcare-associated patient harm.

Utility of P2Y12 Reactive Unit Assessment on Ticagrelor in Cerebral Aneurysms Treated with Intracranial Stenting and Flow Diversion: Cohort Study and Case Report From Two Neurovascular Centers.

BACKGROUND: Dual antiplatelet therapy consisting of aspirin and clopidogrel is the standard of care for neurointerventional stenting and flow diversion. Platelet function testing has been increasingly performed to identify patients with a hypo- or hyper-response to clopidogrel. Ticagrelor has been a popular alternative antiplatelet agent for such patients. We assessed the role of platelet function testing in patients receiving ticagrelor and undergoing stenting or flow diversion. METHODS: The data from patients who had undergone stent-assisted coiling or Pipeline flow diversion of a cerebral aneurysm with ticagrelor therapy at any point during their treatment course from May 2017 to August 2019 at a single academic institution in the United States were retrospectively reviewed. Platelet function testing was used to determine the P2Y12 reactive units (PRUs), and the results were correlated with the procedural complications. RESULTS: A total of 28 patients with 29 aneurysms were treated while receiving ticagrelor. Of the 29 aneurysms, 16 (55.2%) were treated with flow diversion and 13 (44.8%) with stent-assisted coiling. Four thromboembolic complications (13.8%) and no hemorrhagic complications developed. Of the 8 patients with ≥1 PRU value >100, 4 (50%) had experienced a thromboembolic complication. The patients without a PRU value >100 did not experience any complications. CONCLUSION: A risk of thromboembolic complications exists for patients receiving ticagrelor, which correlated with the PRUs in the present preliminary study. The findings from the present study suggest that the safe PRU range for patients receiving ticagrelor should be shifted to 0-100, which is lower than that of clopidogrel, thought to be 60-210. Further validation of the optimal PRU range for patients receiving ticagrelor is necessary.

Utility of platelet function testing in stent-assisted coiling of cerebral aneurysms.

BACKGROUND: Thromboembolic complications are the primary risks of stent-coiling of cerebral aneurysms. The utility of platelet function testing in stent-assisted aneurysm coiling remains controversial. This study aimed to assess a pharmacy-mediated antiplatelet management protocol for stent-assisted coiling. METHODS: Stent-coiled aneurysms at an academic institution in the United States between 2015 and 2018 were retrospectively reviewed. All patients were managed using a pharmacy-mediated antiplatelet protocol, which required repeated platelet function testing and subsequent dose adjustments. Medication dosage, number of adjustments, aspirin reaction units (ARU) and P2Y12 reaction units (PRU), as well as complication rates, angiographic and functional outcome were analyzed. RESULTS: A total of 56 aneurysms (median size 5 mm, range 2.6-14.0 mm) in 54 patients (median age 58.5 years) were treated with stent-assisted coil embolization. Most aneurysms were located at the basilar tip (28.6%). Median pre-procedure ARU and PRU were 442.5 (range 363-594) and 123.5 (range 1-252), respectively. Approximately two-thirds of all procedures required at least one aspirin dose adjustment and 88.5% of procedures required at least one clopidogrel dose adjustment. There were two (3.6%) thromboembolic complications. One of the thromboembolic complications occurred in a patient where the pharmacy-mediated protocol was violated. There were no hemorrhagic complications. Last imaging follow-up demonstrated complete aneurysm occlusion in 83.9%. CONCLUSION: In patients where the pharmacy-mediated antiplatelet protocol was followed, the thromboembolic complication rate was 1.8%. This complication rate compares favorably to those reported in large contemporary series. Nevertheless, the pharmacy-mediated protocol places a significant burden on both the patient and healthcare system.

Minimally Invasive Parafascicular Surgery for Resection of Cerebral Cavernous Malformations Utilizing Image-Guided BrainPath System.

BACKGROUND: The minimally invasive parafascicular approach provides a surgical corridor to reach deep lesions with minimal impact on the surrounding brain tissue. OBJECTIVE: To evaluate the safety and efficacy of this approach utilizing the image-guided tubular BrainPath system (NICO Corp, Indianapolis, Indiana) for the resection of deep and subcortical supratentorial cerebral cavernous malformations (CCMs). METHODS: We performed a retrospective analysis of patients who presented with subcortical CCMs treated with the BrainPath system. Patient demographics, clinical presentation, procedural complications, and clinical and imaging follow-up information were assessed. RESULTS: Six patients were identified between December 2014 and November 2017 at a large volume academic institution in the United States. There were 3 males and 3 female patients with a median age of 25 yr. Locations included frontal, temporal, and parietal lobes. In selected cases, the fiber-sparing trajectory imposed a longer approach than the closest distance to the brain surface. Except for 1 patient who suffered from surgical wound dehiscence, there were no operative complications in any of the cases. All patients remained neurologically stable postoperatively with a mean follow-up of 20 moh. CONCLUSION: This small series suggests that the use of a minimally invasive surgical approach to CCMs utilizing the image-guided parafascicular tubular BrainPath system is feasible, safe, and effective.
