Collaborative Drug Therapy Agreement (CDTA) for Influenza Antivirals in Washington State
A team from the Washington State Pharmacy Association (WSPA), NWCPHP, and PHSKC developed a template Collaborative Drug Therapy Agreement (CDTA) for Influenza Antiviral Medications under a contract with WA State DOH, supported via CDC pandemic preparedness funds. The product of this collaboration is available here, for use by local health officers and by individual authorized prescribers to allow pharmacists to prescribe antiviral medications in case of an influenza outbreak. Although the Collaborative Drug Therapy Agreement may be entered into at any time and submitted to the Washington State Board of Pharmacy, the protocol is intended only to go into effect when authorized by local health officers. The guidance provided here will be updated frequently during an outbreak, so it is important for pharmacists to check these Web sites often for updates:
Web Sites
- CDC's H1N1 Flu Updates
- Washington State Department of Health
- Your local health department's Web site (e.g., http://www.kingcounty.gov/healthservices/health/preparedness/pandemicflu/swineflu.aspx)
