Abstract WP79: Addition Of Multidisciplinary Novel Processes Reduces The Door-to-Needle Time In Acute Ischemic Stroke

Abstract

Introduction: It is well established that reduced door-to-needle (DTN) time leads to improved outcomes in acute ischemic stroke. Rhode Island Hospital is a Comprehensive Stroke Center focused on improving outcomes by seeking novel methods to improve the DTN to below the institutional goal of a median of < 30 minutes. Methods: We sought to reduce DTN time by the following methods: 1) Addition of an electronic DTN Timer appearing in the Electronic Medical Record (EMR) to improve situational awareness of elapsed time in Code Strokes in real time (Figure). 2) Creation of a multidisciplinary Thrombolysis Focus Group to analyze data and improve processes. 3) Increased awareness of metric exclusion criteria and ease of processes for providers to document exclusions. 4) Concurrent review of each thrombolysis case with direct provider feedback and opportunity to appropriately document and clarify delays. 5) Creation of a thrombolysis Time-Out process. Results: The median DTN for the pre-implementation period of January 2020 to August 2021 was 40.3 minutes compared to 35.8 min for the post-implantation period of September 2021 to June 2022. Additionally, the percent of thrombolysis cases meeting the institutional goal of under 30 minutes improved from 22.6% to 29.8% percent (Figure) and when exclusions were applied, this percentage improved from 29.8% to 49.4% (Figure). Conclusion: Novel measures to reduce the DTN time in acute stroke thrombolysis can positively impact both the door-to-needle time and percent of cases under the institutional DTN time goal. Figure 1.
