Diana J. White Cancer Institute Earns Re-Certification for Quality Care


February 22, 2022 – Adventist Health Sonora is proud to announce that the Diana J. White Cancer Institute has earned re-certification from the Quality Oncology Practice Initiative (QOPI®).

The QOPI® Certification Program (QCP™), an affiliate of the American Society of Clinical Oncology (ASCO®), recognized Adventist Health Sonora for successfully completing another three-year certification program for outpatient hematology-oncology practices and meeting nationally recognized standards for quality cancer care. The Diana J. White Cancer Institute initially received QOPI® certification in 2018.

“I am so proud of our team for receiving this certification,” Adventist Health Sonora President Michelle Fuentes said. “The entire oncology team has worked hard to demonstrate the highest standards of care for our patients, and QOPI recognition affirms that.”

This certification puts the Diana J. White Cancer Institute into an elite group of only 16 cancer centers in California.

QOPI® is a voluntary self-assessment and improvement program launched by ASCO® in 2006 to help hematology-oncology and medical oncology practices assess the quality of the care they provide to patients. To become QOPI® Certified, practices must submit to an evaluation of their entire practice and documentation standards. An on-site survey then verifies that the evaluation and documents are correct and that the practices met core standards in areas of treatment, including:

  • Creating a safe environment
  • Staff training and education
  • Treatment planning
  • Patient consent and education
  • Safe chemotherapy administration
  • Monitoring and assessment of patient well-being
