CHICAGO (AP) — An Illinois state audit has found systemic failures in the licensing and oversight of thousands of taxpayer-funded group homes for adults with disabilities.

The Chicago Tribune reports that the nearly 230-page report released Thursday by Auditor General Frank Mautino’s office found communication failures within the state Department of Human Services.

Auditors say officials who license group homes “routinely” didn’t receive findings and reports from those who investigate abuse. The audit also found failures in documenting whether deficiencies were corrected.

The Human Services Department argues that the audit is largely based on dated information that doesn’t include changes underway.

The issues were first exposed in a 2016 Tribune investigation that documented substandard conditions. The newspaper also found that the state oversight remained inconsistent in a follow-up investigation this year .
