Emergency Response

Description

In addition to utilizing syndromic surveillance data to respond to public health threats and prepare for major incidents, local health departments can utilize the data to examine patient volumes in the emergency departments (EDs) of local hospitals. The information obtained may be valuable to hospital and clinic administrators who are charged with allocating resources. 

Indianapolis represents 92% of Marion County’s population. The county’s public hospital and clinic network provide care for 1 in 3 county residents who are Medicaid enrollees or uninsured. To assess the need for extended hours at eight public primary care clinics in Marion County, Indiana, this study examined the hospital’s ED volume. We hypothesize that

changes in the ED volume trends that corresponded to the start or end of usual clinic hours (8am-5pm) would be evidence of clinic hours’ impact on ED use.

 

Objective

This paper highlights the use of syndromic surveillance data to examine daily trends in ED volume at an urban public hospital.

In 2003, the need for a system to track and manage patient status and location was identified by Boston Emergency Medical Services (Boston EMS) and the Conference of Boston Teaching Hospitals. After consultation with EMS (municipal, fire based, and private), hospital, local and state public health and emergency management stakeholders, a core group from Boston EMS and Boston Public Health Commission (BPHC) developed guidelines for a Metro Boston Patient Tracking System. The goal was to provide a system to reunite family members and serve as a tool for managing short term/high impact mass casualty incidents and protracted disease outbreaks.

Since 2004, BPHC Communicable Disease Control Division (CDC) has effectively managed several mass prophylaxis clinics in response to infectious disease outbreaks. However patient data was largely collected on paper based forms, limiting the availability of real-time clinic data to incident command. To address these challenges BPHC CDC began meeting with Boston EMS to define the business processes and information needs during public health emergencies.

 

Objective

To describe the electronic patient tracking system configured by Boston EMS and the BPHC CDC to address information needs during public health emergencies.

Description

Timely outbreak detection, and monitoring of morbidity and mortality among Katrina evacuees, and needs assessment for better planning and response were urgent information intensive priorities during Katrina relief efforts at Houston, and called for immediate deployment of a real-time surveillance and needs assessment system ad hoc, in order to collect and analyze relevant data at the scene. Initial requirement analysis revealed the following capabilities as essential to sustain effective response within the shelters:

• The ability to securely collect and integrate data from evacuees seeking any form of health services from all care providers (academic, volunteers, federal, NGOs and international aid organizations, etc), including demographic information, vital signs, chief complaints, disabilities, chronic conditions, current and past medications, traumas and injuries, exposure to toxic materials, clinical laboratory results, past medical history, discharge notes and diagnoses, and ability to collect free text entries for any other information (similar to a full-blown electronic medical records system).

• Proactive survey of demographic profile, physical and mental health status, as well as special needs assessment (e.g., dialysis, medications, etc) from all evacuees.

• The ability to collect uniform information, using any network-enabled device available: PCs, tablets, and handheld devices. 

• The ability to classify observations by processing sign and symptom, chief complaint, medication, and other diagnostic data (including free text entries) through ad-hoc definition of concepts such as (Gastrointestinal, Respiratory, Fever and Rash, etc). 

 

Objective

This paper presents lessons learned from leveraging Internet-based technologies and Services Oriented Architecture in providing timely, novel, and customizable solutions, just in time and for preparedness against unprecedented events such as natural disasters (e.g., Katrina) or terrorism.

Description

The Connecticut Department of Public Health (DPH), like all public health agencies, is constantly challenged by new health threats and emerging diseases. A major responsibility of these agencies is the rapid and effective communication of information on emerging threats to members of the public who may be potentially exposed. This responsibility for effective risk communication is critical when the public perception of risk is high. The September 11, 2001 terrorist attacks and subsequent anthrax mail attacks (Amerithrax) resulted in a new era of public risk perception and concern. Many new and advanced surveillance systems, developed in response to these events, have increased the need for effective risk communication. For example, the DPH developed its first syndromic surveillance system in September 2001 to monitor for possible bioterrorism events and emerging infections. This resulted in the implementation of a number of risk communication and response protocols. These and other protocols were tested in responding to the recent anthrax contamination of a drum maker’s residence and a multistate rash outbreak.

 

Objective

This paper describes various risk communications techniques used in Connecticut to provide health information to the public following surveillance signal alerts. The use of hotlines and contemporary social networking systems to quickly communicate with targeted populations are compared to the use of news releases and other traditional approaches.

Description

Florida has implemented various surveillance methods to augment existing sources of surveillance data and enhance decision making with timely evidence based assessments to guide response efforts post-hurricanes. Historically, data collected from deployed federal assets have been an integral part of this effort. However, a number of factors have made this type of surveillance challenging: logistical is- sues of field work in a post-disaster environment, the resource inten- sive manual data collection process from DMAT sites, and delayed analysis and interpretation of these data to inform decision makers. The ESSENCE-FL system is an automated and secure web-based ap- plication accessed by FDOH epidemiologists and staff at participat- ing hospitals.

Objective

The Florida Department of Health (FDOH), Bureau of Epidemi- ology, partnered with the U.S. Department of Health and Human Services (HHS) Office of the Assistant Secretary for Preparedness and Response (ASPR) to improve surveillance methods in post dis- aster or response events. A new process was implemented for con- ducting surveillance to monitor injury and illness for those presenting for care to ASPR assets such as Disaster Medical Assistance Team (DMAT) sites when they are operational in the state. The purpose of the current work was to field test and document the operational ex- perience of the newly implemented ASPR data module in ESSENCE- FL (syndromic surveillance system) to receive near real-time automated data feeds when ASPR federal assets were deployed in Florida during the 2012 Republican National Convention (RNC).

BioSense is a national human health surveillance system for disease detection, monitoring, and situation awareness through near realtime access to existing electronic healthcare encounter information, including information from hospital emergency departments (EDs). MCM include antibiotics, antivirals, antidotes, antitoxins, vaccinations, nuclide-binding agents, and other medications. Although some MCM have been extensively evaluated and have FDA approval, many do not (1). Current FDA and CDC systems that monitor drug and vaccine safety have limited ability to monitor MCM safety, and in particular to conduct rapid assessments during an emergency.

Objective

To conduct an initial examination of the potential use of BioSense data to monitor and rapidly assess the safety of medical countermeasures (MCM) used for prevention or treatment of adverse health effects of biological, chemical, and radiation exposures during a public health emergency.

Description

For radiological incidents, collecting surveillance data can identify radiation-related public health significant incidents quickly and enable public health officials to describe the characteristics of the affected population and the magnitude of the health impact which in turn can inform public health decision-making. A survey administered by the Council of State and Territorial Epidemiologists (CSTE) to state health departments in 2010 assessed the extent of state-level planning for surveillance of radiation-related exposures and incidents: 70%–84% of states reported minimal or no planning completed. One data source for surveillance of radiological exposures and illnesses is regional poison centers (PCs), who receive information requests and reported exposures from healthcare providers and the public. Since 2010, the Centers for Disease Control and Prevention (CDC) and the American Association of Poison Control Centers (AAPCC) have conducted ongoing surveillance for exposures to radiation and radioactive materials reported from all 57 United States (US) PCs to NPDS, a web-based, national PC reporting database and surveillance system.

 

Objective

To describe radiation-related exposures of potential public health significance reported to the National Poison Data System (NPDS).

Hurricane Harvey made landfall along the Texas coast on August 25th, 2017 as a Category 4 storm. It is estimated that the ensuing rainfall caused record flooding of at least 18 inches in 70% of Harris County. Over 30,000 residents were displaced and 50 deaths occurred due to the devastation. At least 53 temporary refuge shelters opened in various parts of Harris County to accommodate displaced residents. On the evening of August 29th, Harris County and community partners set up a 10,000 bed mega-shelter at NRG Center, in efforts to centralize refuge efforts. Harris County Public Health (HCPH) was responsible for round-the-clock surveillance to monitor resident health status and prevent communicable disease outbreaks within the mega-shelter. This was accomplished through direct and indirect resident health assessments, along with coordinated prevention and disease control efforts. Despite HCPH’s 20-day active response, and identification of two relatively small but potentially worrisome communicable disease outbreaks, no large-scale disease outbreaks occurred within the NRG Center mega-shelter.

Objective:

1) Describe HCPH’s disease surveillance and prevention activities within the NRG Center mega-shelter;

2) Present surveillance findings with an emphasis on sharing tools that were developed and may be utilized for future disaster response efforts;

3) Discuss successes achieved, challenges encountered, and lessons learned from this emergency response.
