Causes and Outcomes of Legal Intervention Injuries in Chicago
Key data notes
- Because of the national change in coding from ICD-9 to ICD-10 in the fourth quarter of 2015, the final quarter of 2015 is excluded from this analysis.
- The total number of injuries in the "Causes of injury" section exceeds 8,384 because some patients may have more than one cause of injury listed.
- Late effects refers to the onset of medical conditions after the acute phase of an earlier, causal condition has run its course.
