  • Target Entity: California Poison Control System (CPCS)
  • Logic Proof: The CPCS is the specific statewide entity in California comprising four regional centers (Sacramento, San Francisco, Fresno, San Diego) managed by the UCSF School of Pharmacy.
Width checklist
  • Name of the Executive Director (e.g., Stuart E. Heard)
  • Name of the Administering University (University of California, San Francisco / UCSF)
  • Name of the Specific School (School of Pharmacy)
Examiner rationale

The question uses Deep Logic by describing the entity's function and structure (consolidating regional centers for poison advice) without naming the 'California Poison Control System' directly. It requires Wide Aggregation by asking for two distinct attribute types: a specific individual (Executive Director) and an institutional relationship (the administering university school), compelling the agent to synthesize governance details.

Judgment

Score 2 - 0

Both agents correctly identified the California Poison Control System (CPCS) and the administering institution (UCSF School of Pharmacy). However, Agent A correctly identified the Executive Director as Stuart E. Heard. Agent B incorrectly named Dr. Cyrus Rangan as the Executive Director; Dr. Rangan is an Assistant Medical Director within the system, not the Executive Director. Because the prompt explicitly asked for the *current* Executive Director, Agent B's factual error on a key constraint makes Agent A the clear winner.

The California Poison Control System (CPCS) is the statewide organization that consolidates four regional centers to deliver immediate, free expert treatment advice for poison exposures. Established in 1997, CPCS operates as a unified network serving all 58 counties in California, handling over 300,000 calls annually through its 24/7 hotline (1-800-222-1222) [1]. The four regional centers are located in San Francisco, Sacramento (covering the Central Valley and Northern California), Fresno/Madera (serving the San Joaquin Valley), and San Diego (addressing Southern California needs). This consolidation ensures standardized, evidence-based guidance from certified poison specialists, pharmacists, and physicians, reducing unnecessary emergency room visits and improving public health outcomes [2]. CPCS provides multilingual support, educational resources, and collaborates with healthcare providers, public health agencies, and emergency responders to manage exposures ranging from household chemicals and medications to environmental toxins and envenomations. The current Executive Director of CPCS is Stuart E. Heard, PharmD, FCSHP, who has led the organization since its inception, overseeing operations, research, and policy initiatives [3]. Under his direction, CPCS has expanded telehealth capabilities and integrated advanced toxicology data systems for real-time response. The program is administratively hosted and managed by the University of California, San Francisco (UCSF) School of Pharmacy, specifically within its Department of Clinical Pharmacy. This affiliation leverages UCSF's academic and research expertise to support training, innovation, and funding for poison control services [4]. Funding primarily comes from state appropriations, federal grants, and partnerships, ensuring accessibility without charge to callers [1]. CPCS plays a critical role in California's public health infrastructure, preventing morbidity and mortality from poisonings while promoting prevention through community outreach and professional education programs [2].

The program is administratively hosted and managed by the **University of California, San Francisco School of Pharmacy**[4]. This academic partnership ensures the system maintains rigorous clinical standards, provides specialized toxicology training, and integrates cutting-edge research into poison treatment protocols. The four regional centers are located in Fresno (serving Central California), Sacramento (serving Northern California), San Diego (serving Southern California), and San Francisco (serving the Bay Area), creating comprehensive geographic coverage[5]. Each center is staffed by specially trained pharmacists and nurses who provide real-time toxicology consultation to the public and healthcare providers, reducing unnecessary emergency department visits and saving an estimated $270 million in healthcare costs annually[6]. ## References 1.
