RESUMEN
INTRODUCTION: People with haemophilia rely on specialists for their care, yet the specific dosing regimens of treatments prescribed by these specialists have not been widely studied. AIM: The objective of this study is to describe trends in clinician prescribing practices for the management of haemophilia in the United States (US). METHODS: We administered surveys to members of the Hemostasis and Thrombosis Research Society via paper surveys at its in-person annual symposia in 1999 and 2015, and an online survey in 2021. The surveys collected information on haemophilia treatments including factor dosing, inhibitor therapy and gene therapy. RESULTS: Clinicians treating haemophilia for more than 50% of their practice time have increased from 37.5% of respondents in 1999 to 46.3% in 2021. Clinicians prescribing factor concentrates at >40 units/kg for routine bleeding events increased from 0% in 1999 to 29.3% in 2021 in haemophilia A (HA) and from 22.5% to 87.8% in haemophilia B (HB). In 2021, the clinicians reported prescribing emicizumab to treat HA patients (>89.5% paediatric, >85.7% adult) with or without inhibitors at least some of the time. Approximately 78.0% of respondents reported that they expected to recommend gene therapy at least some of time. CONCLUSION: These data indicate changing trends in prescribing practices among US haemophilia specialists during the past 22 years. Preference for high doses of factor (>40 units/kg) has increased during this period. Emicizumab prophylaxis has been prescribed for patients with and without HA inhibitors. Clinicians expect gene therapy to have value for some haemophilia patients.

Objectives: Most acute stroke research is conducted at academic and larger hospitals, which may differ from many non-academic (ie, community) and smaller hospitals with respect to resources and consultant availability. We describe current emergency department (ED) and hospital-level stroke-related capabilities among a sample of community EDs participating in the Emergency Quality Network (E-QUAL) stroke collaborative. Methods: Among E-QUAL-participating EDs, we conducted a survey to collect data on ED and hospital stroke-related structural and process capabilities associated with quality of stroke care delivery and patient outcomes. EDs submitted data using a web-based submission portal. We present descriptive statistics of self-reported capabilities. Results: Of 154 participating EDs in 30 states, 97 (63%) completed the survey. Many were rural (33%); most (82%) were not certified stroke centers. Although most reported having stroke protocols (67%), many did not include hemorrhagic stroke or transient ischemic attack (45% and 57%, respectively). Capability to perform emergent head computed tomography and to administer thrombolysis were not universal (absent in 4% and 5%, respectively). Access to neurologic consultants varied; 18% reported no 24/7 availability onsite or remotely. Of those with access, 48% reported access through telemedicine only. Admission capabilities also varied with patient transfer commonly performed (79%). Conclusion: Stroke-related capabilities vary substantially between community EDs and are different from capabilities typically found in larger stroke centers. These data may be valuable for identifying areas for future investment. Additionally, the design of stroke quality improvement interventions and metrics to evaluate emergency stroke care delivery should account for these key structural differences.
RESUMEN
OBJECTIVE: The American Heart Association recently raised the bar on the timely treatment of acute ischemic stroke (AIS) with intravenous alteplase. Our study looks at the effectiveness of this new standard, by examining the effect of varying door-to-needle times of alteplase initiation on the clinical, quality of care, and efficiency of care outcomes. METHODS: This retrospective case-control study examined 752 AIS patients treated with intravenous alteplase in a large academic health system during 2015-2018, and compared their outcomes after treatment within 30, 45, and 60 min of arrival. The outcomes compared were: (1) clinical - discharge and 90-day modified Rankin Scale (mRS), and post-intravenous alteplase (24-h) NIH Stroke Scale (NIHSS); (2) quality of care - inpatient mortality, 30-day readmission, discharge to home, and disability at discharge; (3) efficiency of care - length of stay (LOS) and index stroke hospitalization costs. Adjusted logistic and linear regression analyses were used to estimate the effects, after controlling for baseline characteristics. RESULTS: Based on the adjusted regression analyses, treatment within 30 min of arrival was associated with better post-treatment mRS and NIHSS scores, and the clinical benefits were reduced when the windows were expanded to within 45 or 60 min. An important finding of the study was that treatment within 30 min of arrival significantly reduced the average LOS. INTERPRETATION: Early intravenous alteplase treatment significantly improved clinical and efficiency of care outcomes. This study provides evidence that meeting the new AHA Target Stroke recommendations will help hospitals improve patient clinical outcomes and reduce LOS, thereby improving the efficiency of care standards.

BACKGROUND: We investigated whether implementation of the end-stage renal disease prospective payment system (ESRD PPS) was associated with changes in thrombolytic therapy use and other aspects of catheter management in hemodialysis (HD) patients. METHODS: Using quarterly, period prevalent cohorts of patients undergoing maintenance HD with a catheter in the US Renal Data System (2008-2015), we studied rates of claims for within- and outside-HD-unit thrombolytic use, and thrombus/fibrin sheath removal, and rates of delayed HD treatment after ESRD PPS implementation, January 1, 2011. Associations between PPS implementation and change in trend of rates of each outcome were assessed using covariate-adjusted Poisson regression, using a piecewise linear function for quarter-time (with breakpoint at PPS implementation). RESULTS: Among an average of 69,428 quarterly catheter users, rates of claims for within-HD-unit thrombolytic use declined from 236.6 (Q1-2008) to 81.4 (Q4-2012) per 100 person-years (P < 0.0001, PPS association with change in trend); rates of claims for thrombus/fibrin sheath removal procedures increased from 3.9 (Q1-2008) to 8.8 (Q3-2015) per 100 person-years (P = 0.0001, PPS association with change in trend). Rates of delayed HD treatment increased from 1.6 (Q2-2008) to 2.3 (Q3-2015) per patient-quarter, although PPS implementation was associated with a decrease in this rising trend (1.6% increase per quarter pre-PPS, 1.2% post-PPS; P < 0.0001, change in trend). CONCLUSIONS: After PPS implementation, thrombolytic use decreased and thrombus/fibrin sheath removal increased. The increasing trend in delayed HD treatment appeared to slow after PPS implementation, but delayed sessions continued to increase year over year for unclear reasons.
