The Opioid Crisis and DI Applicants

3

  • Opioid use is prevalent in the United States
  • It’s unclear how opioids affect health and work capacity
  • Opioid use may be common among people applying for Social

Security Disability Insurance (DI)

  • Opioid use among applicants has implications for the DI program

Research Plan

6

  • Medication information from applications (SDR)
  • 30% sample of DI applicants in each year from 2007 to 2017
  • About 6.5 million applications
  • Machine-learning approach to classify free-form text;

also to classify medications from pull-down lists

  • Wu (2018)
  • Document trends in opioid use overall and by subgroups

Conclusion

16

  • Successfully applied a machine learning algorithm to SSA

administrative data

  • 99% accuracy rate
  • Estimated 65% reduction in costs
  • Opioid use is common among DI applicants
  • What causes changes in opioid use among applicants?
  • Trends in opioid-prescribing practices
  • Changes in the composition of DI applicants
  • DI application is an opportunity to connect opioid users with services

Future Research

17

  • What factors affect trends in opioid use among DI applicants?
  • What is the association between opioid use at application and

DI award or death within five years?

  • Wu, Hoffman, O’Leary work in progress
  • What is the association between opioid use at application and

subsequent employment outcomes?

  • Wu, Hoffman, O’Leary proposal
  • What are the trends in the use of mental health medication among

applicants?

  • Application of Wu’s (2018) machine-learning algorithm
