Lamar Odom was betrayed by several staffers at Sunrise Hospital in Vegas, and we've learned they've been summarily fired.
We're told the workers were all trying to sneak a photo of Lamar as he fought for his life inside the hospital. Our sources say some of them tried to access his medical records, in violation of HIPAA rules.
A rep for Sunrise tells us, "We take all patient privacy very seriously and follow all HIPAA policies in compliance with federal regulations."
As we previously reported ... Lamar's now at Cedars-Sinai in L.A. ... where he's under 24/7 security.
