Summary

This study defines injury care episodes using medical claims data. Limb and trunk injuries require more follow-ups than brain injuries, suggesting rare monitoring for minor brain injury sequelae.

Area of Science:

  • Medical informatics
  • Public health
  • Injury epidemiology

Background:

  • Traditional healthcare episodes are condition-specific, defined by diagnosis codes and timeframes.
  • The study utilizes medical claims data from 1987-1989 to define injury care episodes.
  • Aims to create distinct episodes of care resulting from injuries.

Purpose of the Study:

  • To develop and present a novel method for identifying injury episodes from medical claims.
  • To analyze patterns of care and follow-up for various injury types.

Main Methods:

  • Utilized medical claims data for 102,000 individuals under 65.
  • Identified injury claims using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes.
  • Defined 'clear zones' for follow-up visits based on 10 body regions and hospitalization status to delineate injury episodes.

Main Results:

  • Successfully created 79,564 injury episodes from 295,165 injury claims.
  • Limb and trunk injuries showed the highest frequency and longest intervals between follow-up claims.
  • Brain injuries, including those requiring hospitalization, averaged fewer than two follow-up claims.

Conclusions:

  • Presents a validated method for identifying injury episodes using claims data.
  • Analysis indicates that follow-up for minor long-term brain injury consequences is infrequent.
