The California Department of Public Health has issued $25,000 penalties against 13 hospitals for serious violations that, in some cases, led to patient deaths. Each violation comes with a $25,000 fine, part of an ongoing effort to hold hospitals more accountable for placing patients at risk of death or serious injury. The disclosures come as a result of a state law that took effect in 2007 requiring hospitals to inform health regulators of all substantial injuries to their patients.
