If there are clinical circumstances where it is unclear whether a specimen should be routed through ACPHD or a commercial lab, clinicians should consult with the ACPHD Acute Communicable Disease section during normal business hours M-F 9am – 5pm by calling 510-267-3250.

Preventing Prescription Drug Misuse and Abuse - Opioids Please distribute to all providers in your practice. Prescription drug misuse and overdose is a national epidemic, according to the Centers for Disease Control and Prevention (CDC). Nationally, each year, prescription narcotics result in more fatal overdoses than heroin and cocaine combined and, in 2015, surpassed auto accidents as the number one cause of accidental deaths. In California, deaths involving opioid prescription drugs have increased 16.5 percent since 2006. In 2012, there were more than 1,800 deaths from all types of opioids – 72 percent involved prescription opioids. In Alameda County, deaths from opioid misuse tripled between 2005 and 2014 and hospitalizations for opioid-related, non-fatal overdoses increased by over 74 percent. This advisory provides actions and resources to help clinicians safely prescribe opioid prescriptions.
