The Las Vegas Review Journal is reporting, an investigation of filthy conditions at state-funded homes for people with mental illness concluded that caseworkers failed to conduct monthly visits and did not follow up when serious violations were uncovered. Richard Whitley, state Department of Health and Human Services director, says Health Care Quality and Compliance, the regulatory agency that licenses and certifies other health care businesses, will now monitor and regulate these homes — instead of case workers and other clinical staff. The report says annual inspections were conducted, but workers did not follow up to see if violations were resolved until the next annual inspection. Now, 84 homes in Southern Nevada — nearly 60 percent of the total — were put on 10- and 30-day corrective action plans. Thirty-eight homes were placed on similar plans in Northern Nevada.
