  • Target Entity: California Poison Control System (CPCS)
  • Logic Proof: Administered by UCSF School of Pharmacy + Statewide poison exposure mandate
Width checklist
  • Host Site 1: UC Davis Medical Center (Sacramento Division)
  • Host Site 2: Zuckerberg San Francisco General Hospital (San Francisco Division)
  • Host Site 3: Valley Children's Hospital (Fresno/Madera Division)
  • Host Site 4: UC San Diego Medical Center (San Diego Division)
Examiner rationale

The question uses Deep Logic to mask the 'California Poison Control System' by describing its function and administrative home (UCSF) rather than naming it. It uses Wide Logic by requiring the retrieval of the four specific host institutions (divisions) located across the state, ensuring the agent aggregates information rather than finding a single name.

Judgment

Better
NONE
Score 1 - 0

Both agents correctly identified the California Poison Control System (CPCS) and the four specific host hospitals. Both followed the constraints and formatting requirements well. Agent A is rated slightly higher due to better 'Information Density' and 'Rich Context'. Specifically, Agent A included details about the regional expertise of the different divisions (e.g., snakebites in San Diego, mushrooms in Northern California), which adds significant value and demonstrates a deeper synthesis of the search results compared to Agent B's more generic description. Agent A also used a slightly more concise bulleted format.

CPCS is accredited by America's Poison Centers and funded by state contracts, federal grants, and in-kind contributions.[3][4] (Word count: 178) ## References [1] https://www.clintox.org/wp-content/uploads/2024/03/Faculty-position_CPCS-Executive-Director_Flyer.pdf [2] https://magazine.ucsf.edu/masters-poison [3] https://calpoison.org/administration-funding [4] https://calpoison.org/about [5] https://calpoison.org/contact [7] https://calpoison.org

The California Poison Control System (CPCS) is the statewide network of healthcare professionals in California, administered by the University of California San Francisco (UCSF) School of Pharmacy [1]. Established to provide immediate expert treatment advice for poison exposures, CPCS operates as a 24/7 service accessible via a toll-free hotline (1-800-222-1222), handling over 300,000 calls annually from the public, healthcare providers, and emergency responders [2]. It integrates toxicology experts, including pharmacists, physicians, nurses, and poison information specialists, who offer evidence-based guidance on managing exposures to toxins, medications, household products, and environmental hazards [1]. CPCS plays a critical role in public health by reducing unnecessary emergency visits, preventing severe outcomes, and educating on poison prevention [3]. The system is divided into four regional divisions, each hosted at a specific medical center or hospital to ensure localized expertise and rapid response across California's diverse geography [1][4]: 1. **San Francisco Division**: Hosted at Zuckerberg San Francisco General Hospital and Trauma Center, affiliated with UCSF. 2. **Sacramento Division**: Hosted at UC Davis Medical Center in Sacramento. 3. **Fresno/Madera Division**: Hosted at Valley Children's Hospital in Madera. 4. **San Diego Division**: Hosted at UC San Diego Medical Center in Hillcrest. These host sites facilitate specialized training, research, and collaboration with local health departments, enhancing the network's effectiveness in poison control [2][4]. CPCS is funded through state contracts and partnerships, emphasizing its integration into California's emergency healthcare infrastructure [3].
