  • Target Entity: California Poison Control System (CPCS)
  • Logic Proof: The system is administered by the UCSF School of Pharmacy and consists of the four specified provider divisions.
Width checklist
  • Current Executive Director: Stuart E. Heard (or current incumbent)
  • Division 1: UC Davis Health / Sacramento - Medical Director (e.g., Timothy Albertson)
  • Division 2: UCSF Health / San Francisco - Medical Director (e.g., Craig Smollin)
  • Division 3: Valley Children's Hospital / Fresno - Medical Director (e.g., Rais Vohra)
  • Division 4: UC San Diego Health / San Diego - Medical Director (e.g., Richard Clark or Alicia Minns)
Examiner rationale

The question uses Deep Logic by describing the California Poison Control System through its administrative body (UCSF School of Pharmacy) and function rather than naming it directly. It requires Wide Aggregation by forcing the agent to locate the central Executive Director and then branch out to find the specific Medical Directors for all four geographically distinct divisions (Sacramento, San Francisco, Fresno, San Diego).

Judgment

Score 2 - 0

Agent A correctly identified the Executive Director and the four specific divisions (sites) that make up the California Poison Control System. It also correctly listed leadership figures associated with those sites (though it conflated the title of 'Director' and 'Medical Director' for the Sacramento and San Diego sites, listing the PharmD Directors rather than the MD Medical Directors, the individuals are actually the leaders of those specific centers). Agent B, however, failed catastrophically. It provided the wrong Executive Director (naming a director from an Arizona center). It also hallucinated the division structure, inventing 'South Bay' and 'Greater Los Angeles' divisions which do not exist within the CPCS network (CPCS consists of sites at UC Davis, UCSF, UCSF Fresno, and UCSD). Furthermore, the names provided for these hallucinated divisions were incorrect (e.g., listing a political scientist as a Medical Director). Agent A is the only useful response.

The California Poison Control System (CPCS) is the statewide emergency response network administered by the UCSF School of Pharmacy that provides immediate, free, and expert treatment advice 24/7 for exposure to poisonous or hazardous substances [1][2]. The current Executive Director of CPCS is Dr. Stuart E. Heard [2][3]. The California Poison Control System comprises four distinct divisions that serve different regions of California [1][2]: 1. **Sacramento Division** (UC Davis Medical Center): The Medical Director is Dr. Justin Lewis [3][4]. This division serves Northern and Central California counties. 2. **San Francisco Division** (UCSF): The Medical Director is Dr. Craig Smollin [3][5]. This division covers the San Francisco Bay Area and surrounding regions. 3. **Fresno/Madera Division** (UCSF Fresno): The Medical Director is Dr. Rais Vohra [3][6]. This division serves the Central Valley region. 4. **San Diego Division** (UC San Diego Medical Center): The Medical Director is Dr. Lee Cantrell [3][7]. This division covers San Diego, Imperial, and surrounding Southern California counties. CPCS operates a single toll-free hotline (1-800-222-1222) that automatically routes callers to their regional division based on area code [1]. The system handles over 300,000 cases annually, providing expert consultation to both healthcare professionals and the general public regarding poisonings, drug overdoses, environmental exposures, and envenomations [2]. Each division maintains specialized staff including medical toxicologists, pharmacists, and nurses who are certified specialists in poison information. The system also conducts surveillance, education, and research activities to prevent poisonings and improve treatment outcomes [1][2]. ## References [1] California Poison Control System Official Website - https://calpoison.org/ [2] UCSF School of Pharmacy - California Poison Control System - https://pharmacy.ucsf.edu/cpcs [3] CPCS Leadership and Medical Directors - https://calpoison.org/about/leadership [4] UC Davis Health - Poison Control - https://health.ucdavis.edu/poison-control/ [5] UCSF Department of Emergency Medicine - Toxicology - https://emergency.ucsf.edu/divisions/medical-toxicology [6] UCSF Fresno - Emergency Medicine - https://www.fresno.ucsf.edu/emergency-medicine/ [7] UC San Diego Health - Division of Medical Toxicology - https://health.ucsd.edu/specialties/poison-center/
