The Effect of a Rapid Assessment Zone on Emergency Department Operations and Throughput.

STUDY OBJECTIVE: We examine the effects of a front-end flow model designated the rapid assessment zone on multiple emergency department (ED) operational metrics. METHODS: This was a retrospective, before-after study of consecutive patient visits at an urban community ED. Six-month periods were compared before and after an intervention in 2017 that changed patient flow and the intake process. A lead nurse role splits patient flow immediately on patient arrival according to only age and chief complaint, allowing direct bedding without the bottlenecks of vital sign measurement, full triage assessment, or Emergency Severity Index assignment. A new patient care area (designated rapid assessment zone) preferentially expedites treatment of patients likely to remain ambulatory and serves as flexible acute care space when needed by individual cases and the ED. The outcomes measured were ED length of stay, arrival-to-provider time, the rate of leaving before treatment completion, and the rate of leaving before being seen. Data were analyzed with nonparametric testing, χ2 analysis, and multiple linear regression, controlling for patient visit characteristics, ED daily census volumes, and measurements of boarding patients. RESULTS: We analyzed 43,847 visits in the preintervention and 44,792 visits in the postintervention periods. The intervention was associated with the following changes: median ED length of stay from 203 to 171 minutes (-15.8%), median arrival-to-provider time from 28 to 13 minutes (-53.6%), leaving before treatment completion from 1.0% to 0.8% (-20%), and leaving before being seen from 3.1% to 0.5% (-84%). Regression analysis accounting for multiple confounders demonstrated that the reduced length of stay after rapid assessment zone implementation persisted across Emergency Severity Index levels 2 to 5 and all ED daily census levels. CONCLUSION: The rapid assessment zone model aims to decrease front-end bottlenecks and minimize serial intake assessments at a high-volume, urban ED. It was associated with improved patient throughput and decreased early patient departure. It may represent a useful model for similar centers.

Integrating clinical practice and public health surveillance using electronic medical record systems.

Electronic medical record (EMR) systems have rich potential to improve integration between primary care and the public health system at the point of care. EMRs make it possible for clinicians to contribute timely, clinically detailed surveillance data to public health practitioners without changing their existing workflows or incurring extra work. New surveillance systems can extract raw data from providers' EMRs, analyze them for conditions of public health interest, and automatically communicate results to health departments. We describe a model EMR-based public health surveillance platform called Electronic Medical Record Support for Public Health (ESP). The ESP platform provides live, automated surveillance for notifiable diseases, influenza-like illness, and diabetes prevalence, care, and complications. Results are automatically transmitted to state health departments.

Harnessing electronic health records for public health surveillance.

Electronic medical record (EMR) systems are a rich potential source for detailed, timely, and efficient surveillance of large populations. We created the Electronic medical record Support for Public Health (ESP) system to facilitate and demonstrate the potential advantages of harnessing EMRs for public health surveillance. ESP organizes and analyzes EMR data for events of public health interest and transmits electronic case reports or aggregate population summaries to public health agencies as appropriate. It is designed to be compatible with any EMR system and can be customized to different states' messaging requirements. All ESP code is open source and freely available. ESP currently has modules for notifiable disease, influenza-like illness syndrome, and diabetes surveillance. An intelligent presentation system for ESP called the RiskScape is under development. The RiskScape displays surveillance data in an accessible and intelligible format by automatically mapping results by zip code, stratifying outcomes by demographic and clinical parameters, and enabling users to specify custom queries and stratifications. The goal of RiskScape is to provide public health practitioners with rich, up-to-date views of health measures that facilitate timely identification of health disparities and opportunities for targeted interventions. ESP installations are currently operational in Massachusetts and Ohio, providing live, automated surveillance on over 1 million patients. Additional installations are underway at two more large practices in Massachusetts.

Lessons learned from a collaborative to improve care for patients with diabetes in 17 community health centers, Massachusetts, 2006.

INTRODUCTION: In 2006, the Massachusetts League of Community Health Centers convened a collaborative to systematically improve health care delivery for patients with diabetes in 17 community health centers. Our goal was to identify facilitators of and barriers to success reported by teams that participated in this collaborative. METHODS: The collaborative's activities lasted 13 months. At their conclusion, we interviewed participating team members. We asked about their teams' successes, challenges, and take-home messages for future collaborative efforts. We organized their responses into common themes by using the Chronic Care Model as a framework. RESULTS: Themes that emerged as facilitators of success included shifting clinic focus to more actively involve patients and to promote their self-management; improving the understanding and implementation of professional guidelines; and expanding staff roles to accommodate these goals. Patient registries were perceived as beneficial but lacking adequate technical support. Other barriers were staffing and time constraints. CONCLUSION: Cooperative efforts to improve health care delivery for people with diabetes may benefit from educating the health care team about guidelines, establishing a stronger role for the patient as part of the health care team, and providing adequate technical instruction and support for the use of clinical databases.

Addressing stroke signs and symptoms through public education: the Stroke Heroes Act FAST campaign.

INTRODUCTION: In 2003, only 18% of Massachusetts adults were aware of all signs and symptoms of stroke, but 80% would call 9-1-1 if they thought someone was having a stroke or heart attack. Because early recognition leads to early treatment and improved clinical outcomes, increasing symptom recognition could have an impact on stroke survival and stroke patients' quality of life. METHODS: We conducted secondary research to identify messages with evidence-based effectiveness for communicating stroke signs and symptoms. From these results, a Stroke Heroes Act FAST animation was created and concept-tested. Non-Hispanic white and non-Hispanic black women aged 40 to 64 years received education on stroke signs and symptoms. Knowledge change about stroke signs and symptoms was calculated immediately following and 3 months after the education session. RESULTS: Using Stroke Heroes Act FAST educational materials that were developed, 72 women (mean age, 54 years; 15.5% were non-Hispanic blacks) received education about signs and symptoms of stroke and took the pretests and posttests to assess knowledge change. Immediately after the education session, significant increases were seen in the percentage of participants who recognized that facial droop (92% vs 99%, P = .02) and arm weakness or numbness (86% vs 97%, P = .004) were symptoms of stroke. Of the 65 participants who were given the 3-month follow-up survey, 100% remembered slurred speech and facial drooping as symptoms; 98.5% recalled arm weakness or numbness; and 97% would call 9-1-1 if they thought someone was having a stroke. None of these is a significant change from the posttest. CONCLUSION: The Stroke Heroes Act FAST kit may be a useful tool for improving knowledge of stroke signs and symptoms among adults.
