Background Advancement in neurointervention is frequently driven by the introduction of new technology and devices that improve procedural efficacy and patient outcomes. For physician-innovators, customer discovery—or the process of directly engaging with end users to explore workflows and associated challenges—offers a structured way to identify meaningful problems and guide early innovation. This primer aims to outline stepwise guidance for conducting customer discovery within neurointervention to characterize key areas of unmet need. Methods We detail stepwise guidance for conducting customer discovery founded on foundational business literature. To illustrate this process, we conducted five interviews with expert neurointerventionalists engaged in clinical innovation. Interview transcripts were reviewed and analyzed to track emerging themes, and responses were synthesized into a neurointerventionalist customer profile. Results Responses from interviewed neurointerventionalists suggested that safer vascular access, tools to support treatment prognostication, and condition-specific device design are unmet areas of need. Moreover, interviews revealed broader concerns about stagnation in device innovation and barriers within regulatory and institutional pathways. Conclusions Structured customer discovery identifies unmet needs that may be overlooked when device development is solely driven by technical breakthroughs or published outcomes. By outlining an actionable framework for customer discovery in neurointervention, we provide a practical model for aligning future innovation with real-world clinical challenges.

ABSTRACT Background Intracranial and extracranial hemorrhages are significant causes of morbidity and mortality. Emergency medicine pharmacists (EMPs) can play a crucial role in anticoagulation reversal by identifying patients on anticoagulation, selecting the optimal anticoagulation reversal agent, and ensuring adequate dosing and prompt administration. The goal of this systematic review and meta‐analysis was to determine the impact EMPs have on time to anticoagulation reversal and patient outcomes in anticoagulation‐associated hemorrhages. Methods A medical librarian performed a literature search in EBSCO CINAHL, Ovid Cochrane Central Register of Controlled Trials, Ovid Embase, Ovid Medline, Scopus, and Web of Science Core Collection from inception to January 2025 for all types of oral anticoagulants and for life‐threatening bleeding that required emergent reversal. Newcastle‐Ottawa was used to assess the risk of bias, and Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to assess the level of certainty of the evidence. Random effects models estimating mean differences and 95% confidence intervals are reported. Results There were 2445 titles and abstracts screened, with 44 undergoing full‐text evaluation. Six observational studies including 219 patients who received an anticoagulation reversal agent with the presence of an EMP and 198 patients who received a reversal agent without an EMP were included. Time from emergency department (ED) presentation to anticoagulation reversal agent administration (75.60 min, 95% confidence interval [CI]: −101.7 to −49.5) and time from medication order to administration were faster with an EMP (−18.7 min, 95% CI: −23.5 to −14.0). There was no difference in short‐term mortality. The included studies had a high risk of bias and were deemed very low quality of evidence. Conclusion EMP involvement in patient care during anticoagulation reversal of acute hemorrhages improved time to anticoagulation reversal agent administration. Larger scale, higher‐quality studies are necessary to assess the value of EMPs in improving patient‐centered outcomes.

Introduction Alcohol is consumed by an estimated 137.4 million people in the USA 12 years of age and older and, as a result, is estimated to have caused about 140 thousand deaths among people 20 to 64 years of age each year from 2015 up to and including 2019. Methods The proposed review of the evidence on alcohol’s impact on health aims to produce conclusions to inform the Dietary Guidelines for Americans, 2026–2030 . A multi-method approach will be utilised to formulate conclusions on (i) weekly (ie, average) thresholds to minimise long-term and short-term risks of morbidity and mortality, (ii) daily thresholds to minimise the short-term risk of injury or acute illness due to per occasion drinking, (iii) alcohol use among vulnerable populations (eg, pregnant women) and (iv) situations and circumstances that are hazardous for alcohol use. To inform expert decisions, this project will also include a systematic review of existing low-risk drinking guidelines, a systematic review of meta-analyses which examine alcohol’s impact on key attributable disease and mortality outcomes, and of estimates of the lifetime absolute risk of alcohol-attributable mortality and morbidity based on a person’s sex and average level of alcohol use. The systematic reviews were designed in accordance with the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P). The preliminary conclusions produced as a result of this project will undergo public consultation, and data from these consultations will be qualitatively analysed. The results of the public consultations will be used to further revise and refine the project’s conclusions. Ethics and registration The study was granted an ethics exemption as only secondary data sources and unidentifiable public consultation will be utilised. Systematic reviews are pre-registered with PROSPERO (registration numbers CRD42024584924 and CRD42024584948). Dissemination This project will establish a scientific consensus concerning alcohol’s impact on health. This consensus is imperative for informing the upcoming Dietary Guidelines for Americans, 2026–2030 , and for better informing individuals about the health risks associated with alcohol use.

Purpose: Despite the 2022 American Heart Association/American College of Cardiology guidelines recommending cardiac rehabilitation (CR) after aortic dissection repair, both patient participation in CR and the associated clinical outcomes remain poorly understood. Methods: Adults (≥18 years of age) discharged alive following thoracic aortic dissection surgery across the Mayo Clinic Enterprise (January 2012 to November 2022), with follow-up until May 2024, were included (IRB #24-001141). Data were presented using summary statistics and logistic regression modeling. Results: A total of 186 patients were referred; 37% were female, and the median age was 64 (51, 73) years. Dissections were classified as type A (43%), type B (18%), or a combination, and 55% had residual dissection. Over half (53%) did not start CR, with older age (aOR = 0.97: 95% CI, 0.94 - 0.99; P = .003), family history of aortic dissections and/or aneurysms (aOR = 0.17: 95% CI, 0.04 - 0.54; P = .005), and tobacco use (aOR = 0.35: 95% CI, 0.13 - 0.91; P = .037) being associated with lower odds of enrollment. Of the 87 who enrolled, 34 did so at a Mayo Clinic facility. There were no complications, with no difference in adverse outcomes. Among those with evaluations at graduation from CR (n = 21), quality of life (Dartmouth index 16 [14, 19] vs 25 [22, 30]; P = .002) and 6-minute walk distance (488 [375, 531] vs 302 [235, 398] m; P = .001) improved. Conclusions: Following thoracic aortic dissection repair, CR significantly improved quality of life and functional capacity without adverse events. Further work is needed to improve enrollment and establish data-driven safety margins for exercise.

Background: Piperacillin-Tazobactam (PTZ) is often used to treat community-acquired intra-abdominal infections (CA-IAIs) despite common causative pathogens being susceptible to more narrow-spectrum agents. However, susceptibility to PTZ among these predominant pathogens has been declining. Antibiotic de-escalation to non-antipseudomonal beta-lactams whenever possible is an important strategy to prevent the development of resistance to PTZ. Objective: The purpose of this study is to assess PTZ length of therapy in patients with CA-IAI, by comparing patients who received a pharmacist-led intervention involving the de-escalation of PTZ to narrow-spectrum regimens with those who did not receive the intervention. Methods: A retrospective analysis was conducted among patients >18 years old and admitted with CA-IAI empirically placed on PTZ between January 1, 2022, through June 30, 2022 (pre-intervention group), and January 1, 2024, through June 30, 2024 (post-intervention group). A total of 246 patients were included in the pre-intervention group and 129 patients in the post-intervention group. The utilization of PTZ, hospital length of stay (LOS), and treatment-associated complications were assessed using linear and logistic regression model, respectively. Results: Compared with patients in the pre-intervention group, those in the post-intervention group had a mean 1.2-day reduction in PTZ length of therapy (2.3 vs 1.2 days, P < 0.001). There was no difference in LOS, (β = 0.001, 98% confidence interval [CI] −1.29 to 1.29; P = 0.477), hospital readmission within 30 days due to IAI (odds ratio [OR] = 0.85, 98% CI = 0.51 to 1.44; P = 0.56), treatment-associated complications during current hospitalization (OR = 0.77, 98% CI = 0.45 to 1.32; P = 0.35), development of Clostridium difficile -associated diarrhea (OR = 3.29, 98% CI = 0.77 to 22.4; P = 0.14), or medication toxicity (OR = 2.07, 98% CI = 0.79 to 6.08; P = 0.15). Conclusion and relevance: The use of narrow-spectrum antibiotics for the empiric treatment of CA-IAI-reduced PTZ length of therapy and did not result in adverse clinical outcomes.
