Outline
• Background• Project
– Objectives for research presented today • Methods/Findings (1)• Methods/findings (2)• Methods/findings (3)• Discussion • Next steps
• Diagnosis: – consider work-related exposures and risks
• Treatment and management:– Consider impact of working patterns (shift) on
treatment/management decisions.– Address safe ‘return to work’ for patient and
community.
• Secondary use of data:– Public health activities, registries, vital records….
Benefits
What are the needs?
• Clinicians need:– Ability to view textual information about a
patient’s occupation and industry (I&O)
• Systems need:– Access to structured and standardized
(coded) information to perform clinical decision support or surveillance

Project goal
To define questions and suggested wording to gather codable I&O information through a patient user interface (e.g., PHR or patient portal) with limited burden.
The coded I&O information should be useful for public health surveillance and clinical decision support
Objectives: initial research
• Evaluate logic in guidance for gathering and coding I&O
• Identify and evaluate questions (and answer sets) currently used in national surveys and EHR
• Assess clinical guidelines for I&O requirements
Methods (1)
• Reviewed guidance documents for:– Funeral directors to complete death certificates
(DHHS (NIOSH) Publication No. 2012-149)– Cancer registrars to abstract from the medical
record. (DHHS (NIOSH) Publication No. 2011-173)– Vital records coders to code entries on death
certificates (DHHS, Instruction manual part 19: industry and occupation coding for death certificates, 2003)
– BRFSS interviewers provided by Massachusetts Dept of Public Health
Funeral director can ask for detail
Reference: Funeral directors to complete death certificates (DHHS (NIOSH) Publication No. 2012-149)
Cancer registrar’s abstract from EHR
Reference: A Cancer Registrar’s Guide to Collecting Industry and Occupation
Vital record coders apply heuristics when products are mentioned
Reference: Instruction Manual Part 19 Industry and Occupation Coding for Death Certificates, effective 2003
Method (2)
• Evaluated questions in surveys:– The American Community Survey– National Health Interview Survey (NHIS)– Multi-Ethic Study of Atherosclerosis (MESA)– Death certificate– National Health and Nutrition Examination Survey (NHANES)– Behavioral Risk Factor Surveillance System (BRFSS) 2013 I/O
Module– REGARDS study– Current Population Survey
• Assessed EHR entry screens (general/specialty)
Occupation American community survey
What kind of work was this person doing? (For example: registered nurse, personnel manager, supervisor of order department, secretary, accountant)
Death certificate DECEDENT'S USUAL OCCUPATION (Indicate type of work done during most of working life. DO NOT USE RETIRED).
MESA What kind of work do/did you do or what was your job title? (e.g. registered nurse, personnel manager, auto mechanic, accountant, grinder operator, etc.)
NHANES What kind of work {were you/was SP] doing? (For example: For example: farming, mail clerk, computer specialist.)
NHIS What kind of work were you doing? (For example: farming, mail clerk, computer specialist.)
REGARDS (if currently ‘employed for wages’)
1. What is your job title?2. What are your main job activities or job duties?
BRFSS 2013 What kind of work do you do? For example, registered nurse, janitor, cashier, auto mechanicPrompt: if respondent is unclear, ask: “What is your job title?”
Current Population Survey
What kind of work (DO/DOES/DID) (name/you) do, that is, what (is/was) (your/his/her) occupation? For example: plumber, typist, farmer
Job dutiesSurvey/Form Question/Name
American community survey
What were this person’s most important activities or duties? (For example: patient care, directing hiring policies, supervising order clerks, typing and filing, reconciling financial records)
Death certificate None
MESA What are/were your most important activities or duties? (e.g. patient care, directing hiring policies, repairing automobile, reviewing financial records, operating grinding mill, etc.)
NHANES What were {your/SP’s} most important activities on this job?(For example: sell cars, keeps account books, operates printing press.)
NHIS What were your most important activities on this job or business?(For example: sell cars, keeps account books, operates printing press.)
REGARDS What are your main job activities or job duties?
BRFSS 2013 None
Current Population Survey
What (are/were) (your/his/her) usual activities or duties at this job?For example: typing, keeping account books, filing, selling cars, operating printing press, laying brick.
Industry Survey/Form Question/Name
American community survey
What kind of business or industry was this? Describe the activity at the location where employed. (For example: hospital, newspaper publishing, mail order house, auto engine manufacturing, bank)
Death certificate KIND OF BUSINESS/INDUSTRY
MESA What type of business or industry is/was this? (e.g., hospital, newspaper publishing, mail order house, auto repair shop, bank, etc.)
NHANES What kind of business or industry is this? (For example: TV and radio mgt., retail shoe store, state labor department, farm.)
NHIS What kind of business or industry was this? (For example: TV and radio mgt., retail shoe store, State Department of Labor)
REGARDS What kind of business or industry is this?
BRFSS 2013 What kind of business or industry do you work in? For example, hospital, elementary school, clothing manufacturing, restaurant.
Current Population Survey
What kind of business or industry is this?*Read if necessary: What do they make or do where (you/he/she) (work/works)?

• Evaluated I&O required for occupationally-related clinical guidelines :– Disease: work-related asthma– Exposure: asbestos– Risk factor: shift work
• What are the triggers for clinical decision support?
Work-Related Asthma

Key findings
• Clinical guidelines revealed I&O information required to trigger decision support logic.
• Current EHRs interfaces were missing information, especially industry-related concepts.
• Documentation of either or both occupation and industry is necessary to trigger clinical decision support.
• Information in surveys and EHR often varies and inadequate for applying logic in guidelines.
• The analysis revealed content needed to capture I&O from users (patients) with goal of automated conversion to structured/coded I&O.
• Some heuristics in coding logic may be avoided if persons can document their own I&O information.
• Strategies needed to allow users to:– document textual I&O information – Select appropriate categories and codes for decision support and
surveillance.
Conclusion
Next steps
• Testing trial questions and workflow– Capture current I&O, then usual and past
• Strategies for capturing I&O in web interface:– Provide guidance (good/bad examples)– ‘Force’ with branching logic – Prompt for more complete/accurate response– Autocode narrative information using heuristics – Present relevant terms (census ‘categories’) based
on user’s input, and allow user to drill
Next steps
Interactive user-centered design to test interface usability:
– Iterative rounds of 5-9 users (total 36 users)– Compare:
• Supervisor’s description (alternate-form reliability)• Participant’s entry into interface (today vs 2 weeks later
(test-retest reliability)• Participant’s description during interview (criterion validity)• Participant’s selection in NIOSH intelligent dropdown tool
• Document requirements
