The report (PDF) just came out. From USA today:
The congressional investigative agency selected 10 deaths to examine in depth and found reckless practices, inadequate training and misleading marketing. It also found what Rep. Todd Platts, R-Pa., called "horrific" examples of abuse.
Other common problems included:
• Ineffective management
• Untrained staff
• Inadequate nourishment
• Reckless or negligent operating practices
• Inadequate equipment
The agency is examining how such facilities are regulated and is expected to make recommendations next year.
