1.1 User Story Narrative
This user story covers one setting in which data are collected: Hospital Emergency Department.
A patient in his late teens presents with flu-like symptoms at a hospital emergency department in mid-August. The
intake demographic data entered into the Electronic Health Record (EHR) includes date of birth, gender, home
address, work address, current occupation, and current industry. Intake clinical data includes height and weight.
The emergency room physician interviews the patient regarding the presenting symptoms and notes the youth is
a farm worker. The physician inquires about the activities of the teen prior to the onset of the symptoms and
learns that the patient was picking fresh fruit at a nearby orchard. Based on the symptomology and work activities
of the youth, the physician suspects acute pesticide poisoning. This information is captured in the EHR. The
electronic health record system indicates to the physician that suspected and confirmed pesticide poisonings are
a reportable condition within his state and that he is to indicate if the current case is confirmed, or suspected. The
physician marks the case as suspected and continues to provide symptomatic treatment to the teen.
The ED information is forwarded to the state health department based on the “suspected” pesticide poisoning
item marked in the EHR. The health department looks for similar EHR reports from other hospitals in the same
area. Five additional “suspected” poisonings are identified that occurred on the same date. All individuals
reported working for the same employer. Based on these reports, the health department contacts the state
department of agriculture and initiates a full investigation of the cases.
1.1.1 Goal
The goal of the initial exchange of case information to the health department is to provide timely information to
public health about a pesticide chemical poisoning at a workplace. Healthcare provides details about a recent
case of pesticide poisoning – e.g., within 30 days of diagnosis or treatment of the illness – to enable the health
department to both follow up on individual cases and to identify workplaces or working conditions/practices that
may present a current threat to the health of other workers.
Further, the public health department uses data from the case reporting program to identify risk factors for
occupational illness, identify populations at increased risk, and help estimate the incidence of pesticide-related
illness. The resulting information is provided back to healthcare, often accompanied by information relevant to the
prevention, diagnosis, treatment and referral of pesticide poisoning. Data from state pesticide poisoning
surveillance programs may also be shared with NIOSH and aggregated in order to provide information about
broader trends in occupational exposures and/or illness. Most states choose to use the case definition and
common set of data elements provided by NIOSH for pesticide poisoning surveillance (see attached spreadsheet
of data elements).
1.1.2 Data Reporting/Exchange Participants (Actors) and Events (Workflow)
Events
1.The patient enters the Hospital Emergency Department (ED).
2. Initial chief complaint, demographic and expected payer information are obtained by an ED reception clerk or
nurse in the ED and entered into the hospital clinical visit EHR system. Demographic and expected payer
information is also used to initiate the Uniform Billing form for this ED visit.
3. Initial Chief Complaint information is forwarded to a triage nurse who determines when the patient will be
summoned for further examination.
4. When summoned, the patient is taken to an examination room by a nurse, who obtains additional chief
complaint information and basic medical information (temperature, blood pressure, etc…). These data are
entered into the record initiated when the patient was admitted to the ED.
5. The attending physician looks at the information in the EHR, conducts the examination with the patient, orders
additional tests as necessary, and enters evaluation and treatment information.
6. Based on data entered by the physician, the EHR system flags actionable items back to the physician,
including clinical decision support options, or notes on reportable conditions. In this case, the system flags that
suspected pesticide poisoning is a reportable condition in the physician’s state and provides the option to indicate
“suspected” or “confirmed”.
7. Physician documents the reportable condition information using the EHR, which automatically sends the
information to the state public health department directly or via the state data exchange system.
8. As needed, the state data exchange system forwards the reportable condition information to the appropriate
State Health Department division.
9. As needed, the State Health Department queries the State data exchange system to identify similar cases that
occurred on the same date as the sentinel case.
10. The state data exchange provides data on similar events to the Health Department.
1.2.3 Data

1.2.4 Standards
Currently, health care providers (individual providers, hospitals etc.) submit data to public health departments in
paper or electronic format; the method of submission varies by state and by condition. Following diagnosis by a
health care provider, a report of occupational pesticide poisoning may be submitted via an emailed or faxed form
or reported over the phone. (Case reports of occupational pesticide reporting are also generated by Poison
Control Centers and may be sent in batches to state health departments with an occupational pesticide poisoning
surveillance program; that scenario is not described here.)
State public health laws set the requirements for occupational condition reporting; there are minor variations by
state in the data elements collected. In general, required data elements include provider information, patient
information (name, age, gender, race and ethnicity, address) patient employer and occupation, industry of
employer, diagnosis, and details of incident such as place of injury, known or suspected exposures that caused
the illness etc. A sample reporting form (New Jersey Department of Health) can be found at the following link:
http://www.state.nj.us/health/forms/occ-31.dot
At present, many of the data elements required by these reports (i.e., patient personal information and
demographics, provider information) are captured in the EHR but may not be accessible from the clinical module,
and interoperability standards exist to support exchange of these elements. A recent Institute of Medicine report
details findings of a committee that studied the rationale for and feasibility of including occupational information in
the EHR. The IOM report can be found at the following link:
http://www.iom.edu/Activities/Environment/OccupationalHealthRecords.aspx. Efforts are currently underway to
ensure useful inclusion of work information, including occupation and industry,, in the clinical module.
NIOSH is preparing to publish a relational data model of work information for health IT. The model includes
potential datasets, all of which have been coded. For example, the combination of Bureau of Census (BOC) I/O
codes1 and NIOSH-added codes (e.g., for unpaid workers) – identified as the CDC_Census system in the Public
Health Information Network Vocabulary Assignment and Distribution System (PHIN VADS) 2 – can be used to
code patient I/O in the EHR. The CDC_Census code sets are used to classify the I/O information provided by
respondents in most major U.S. health surveys. Employer information is typically present in current EHR
Systems; however it may not appear in the clinical module. In addition, NIOSH has supported the development of
an “Occupational Data for Health” (ODH) template for work information in the CDA social history section; the
ODH template is available as a draft standard for testing with Integrating the Health Enterprise (iHE) and is being
tested within the Healthy Weight profile at the 2014 Connectathon.
The use of the International Classification for Disease 10th Revision Clinical Modifications (ICD-10-CM) will
become the new required data standard for the Health Insurance Portability and Accountability Act (HIPAA)covered entities on or after October 1, 2014:
http://www.cms.gov/Medicare/Coding/ICD10/downloads/ICD-10MythsandFacts.pdf
Codes
Classification systems exist to support the exchange of structured industry and occupation (I/O) and other work
information data (data elements required for case reports of occupational conditions). Structured I/O data is not
yet captured and managed by most EHRs but the capture of coded I/O data has been proposed as an EHR
Certification Criterion for the 2017 Edition. However, fields for I/O data appear in cancer registries and death
certificates. Additionally, I/O data are collected by many national surveys as text and subsequently coded.
Code sets for the ICD-10CM systems, including the external cause rubric, are available at:
http://www.cms.gov/Medicare/Coding/ICD10/Index.html. The ICD-10-CM External Cause Codes provide basic
casual information for acute injuries and poisoning. The External Cause Codes include specific codes of the
immediate cause of the injury or poisoning, activity at the time of the event, status of the person at the time of the
event, and the location where the event occurred. The ICD-10-CM code source will be required for all medical
facilities by CMS effective October 1, 2014. Work is currently ongoing to ensure harmonization of CDA-Release 2
and HL-7 concerning the use of the ICD-10CM code set.
1.2.4 Other Information
Efforts to estimate work-related events indicates that nearly 16 workers in the United States die each day from
injuries sustained at work, and 134 die from work-related diseases. Each day approximately 9,000 workers are
treated in emergency departments for occupational injuries or disease. Work-related disease and injury account
for a considerable fraction of total direct and indirect costs related to health outcomes. In 2005, workers’
compensation costs for employers totaled an estimated $89 billion. There are no systems in place to track
occupational injuries, poisoning, or chronic conditions for the entire workforce, creating a gap in public health
efforts at prevention. Electronic case reporting of occupational pesticide poisonings and other occupational
conditions will remain a critical component of the public health surveillance of work-related conditions in the U.S.
