A cumulative risk index for use in the medical home.

We showed that a practice-friendly CRI, based on characteristics typically available in the medical record, could help identify families less likely to support development concurrently at 1 year of age and predictively at 2-3 years. School functioning at 8 to 10 years was also significantly better in children with a low CRI at 1 year. The CRI could be a useful tool for both clinicians and researchers needing a simple tool for risk assessment.
