Federal regulators, however, have not yet received the newest report from state inspectors.
Parks declined to discuss patient care issues with The Times, citing patient confidentiality. But in a statement, she defended the hospital.
"It is unfortunate that the many thousands of patients and their families who have been successfully treated at Las Encinas do not have an opportunity to tell their stories to the press," Parks wrote. "It is disappointing to realize that the only stories the media wishes to carry ignore the outstanding care we provide year after year."
But the families of two men who died while in Las Encinas' care said they still have many questions about what went wrong at a hospital they believed would provide world-class treatment.
Both young men wanted to be treated at Las Encinas because of its affiliation with Dr. Drew Pinsky, co-medical director of its chemical dependency unit, their families said.
Pinsky, best-known for his nationally syndicated "Loveline" radio program and his reality TV show on VH1, "Celebrity Rehab With Dr. Drew," has been affiliated with the hospital for more than 20 years. He did not treat either man and did not respond to multiple requests for comment about the latest findings.
Last summer, Pinsky told The Times his heart was broken over the deaths there and defended the facility as an "excellent hospital." But he seemed to distance himself from the hospital, calling it a "bizarre misconception" that people associated him with the facility.
At that time, he was the only physician whose picture was featured on the Las Encinas website. Currently, the hospital's home page features links to two news articles that refer to Pinsky's role at the hospital. His affiliation with Las Encinas is included in his biographical information that appears on Loveline's website and in numerous VH1 press releases.
Pinsky's reputation drew Alex Clyburn's family to the private hospital, his mother said. Clyburn, a 23-year old Cal State Northridge student, sought substance abuse treatment at Las Encinas last April.
Just before he was admitted, Clyburn took a large dose of OxyContin, a painkiller, and Xanax, an anti-anxiety drug. After admission, hospital staffers gave him a mix of medications intended to ease his withdrawal. His mother, a nurse, later said she expressed concern to hospital staffers that the drugs would cause respiratory distress. She said a nurse assured her that they would check on her son through the night.
Clyburn was found dead in his room the next morning.
A mental health worker had falsified patient records showing that Clyburn was checked on every 15 minutes, investigators found. Logs filed by the worker even reported Clyburn as sleeping just five minutes before a nurse discovered his body "cold & stiff to touch with a blue face," an indication he had been dead for some time.
The hospital said it fired the worker and promised to monitor patients undergoing detoxification closely.
What Clyburn's family did not know was that 16 months earlier, another young man had died after going unmonitored overnight by Las Encinas staff.
Leo Grassini, 26, was found dead in his room five days after he sought treatment for addiction at the hospital shortly after Thanksgiving 2006. Like Clyburn, he had specifically told his parents he wanted to go to Las Encinas.
"He listened to 'Loveline' when he grew up, and Drew Pinsky worked there, and he felt that Drew Pinsky could help him with any problems he had," said his father, Lawrence Grassini, an attorney in the San Fernando Valley.
According to medical records, Leo Grassini had been prescribed narcotic medication intended to help wean him off opiates. He was later found lethargic and with depressed breathing and was rushed to the emergency room at San Gabriel Valley Medical Center, according to records. After emergency room doctors stabilized Grassini and sent him back to the private psychiatric hospital, a Las Encinas doctor ordered that his vital signs be monitored "very closely for the next 24 hours."
Instead, his therapist found Grassini dead in his bed the next morning. His body was discovered only after he failed to show up for a morning session. According to medical records, there were signs he had been dead for some time; his face and chest had turned purple and were cool.
