  • Stuart Heard identified as Medical Director of the Sacramento Division of the California Poison Control System
  • Richard Clark identified as Medical Director of the San Diego Division of the California Poison Control System
  • Thomas Kearney identified as Medical Director of the San Francisco Division of the California Poison Control System
Width checklist
  • Rais Vohra – Emergency Medicine specialty
  • Rais Vohra – Faculty appointment at UCSF Fresno (University of California, San Francisco Fresno Medical Education Program)
  • Stuart Heard – Emergency Medicine specialty
  • Stuart Heard – Faculty appointment at UC Davis School of Medicine
  • Richard Clark – Emergency Medicine specialty
  • Richard Clark – Faculty appointment at UC San Diego School of Medicine
  • Thomas Kearney – Pharmacy/Emergency Medicine or Clinical Toxicology specialization
  • Thomas Kearney – Faculty appointment at UCSF School of Medicine
Examiner rationale

The question uses the structural logic of a statewide poison control system (Deep reasoning) to require identification of the specific regional medical directors without naming them directly. It then requires aggregation of biographical and professional details (Wide scope) from multiple university and hospital sources, ensuring that the responder must synthesize information across all regional divisions rather than rely on a single document.

Judgment

Tie
BOTH
Score 0 - 0

First, Deep Logic: Agent A identifies four divisions but assigns incorrect medical directors for three of them (San Francisco, Sacramento, and Fresno), failing the core entity matching for most divisions. Agent B does not identify the required medical directors at all, explicitly stating the information is unavailable. Thus, both fail Deep Logic. Second, Width/Completeness: Agent A provides specialties and faculty roles, but since three directors are incorrect, the majority of its details are tied to the wrong individuals—failing the WIDTH checklist. Agent B provides none of the required director names, specialties, or faculty appointments, failing WIDTH entirely. In terms of User Experience, Agent A is better formatted and more comprehensive, but its substantive inaccuracies (hallucinated or incorrect directors) severely undermine accuracy. Agent B is accurate in its caution but effectively provides no answer, making it unhelpful. Because both agents fail the core entity requirements and miss major checklist items, this is a LOW quality tie.

Clark** directs the San Diego Division at UC San Diego, where he is Professor of Medicine and Emergency Medicine, specializing in medical toxicology and emergency medicine [1][2]. **Dr. Kent R. Olson** leads the San Francisco Division at UC San Francisco, holding positions as Clinical Professor of Medicine and Emergency Medicine, with expertise in medical toxicology and emergency medicine [3][4]. **Dr. Timothy E. Albertson** serves as Medical Director of the Sacramento Division at UC Davis, where he is Professor of Medicine, specializing in pulmonary and critical care medicine, and also holds an appointment in emergency medicine [5][6]. **Dr. Patil Armenian** directs the Fresno Division at UCSF Fresno (UC San Francisco Fresno Medical Center), where she is Associate Professor of Emergency Medicine, specializing in medical toxicology and emergency medicine [7][8]. Each director maintains active roles in clinical education, poison control consultation services, and academic research. ## References [1] https://www.calphos.org/about-us/leadership/ [2] https://profiles.ucsd.edu/richard.clark [3] https://www.calphos.org/about-us/leadership/ [4] https://profiles.ucsf.edu/kent.olson [5] https://www.calphos.org/about-us/leadership/ [6] https://health.ucdavis.edu/pulmonary/team/albertson.html [7] https://www.calphos.org/about-us/leadership/ [8] https://www.fresno.ucsf.edu/emergency-medicine/faculty/armenian-patil

The search results provided do not contain sufficient information to comprehensively identify the medical directors for each California Poison Control System regional division along with their specialties and faculty appointments. The available information reveals limited leadership details. Dr. Cyrus Rangan is identified as **Assistant Medical Director** of the overall California Poison Control System[2], but his specific division assignment and detailed credentials are not documented in these results. Justin Lewis, PharmD, DABAT, is listed as Managing Director of the Sacramento division[4], though his role is administrative rather than medical. The search results confirm that CPCS operates through four primary regional divisions: Fresno/Madera (affiliated with Valley Children's Hospital), Sacramento (UC Davis Medical Center), San Diego (UC San Diego Medical Center), and San Francisco (Zuckerberg San Francisco General Hospital)[5]. However, the specific medical directors for each division are not identified in the provided search results. CPCS is described as "the largest single provider of poison control services in the United States"[7], and the system maintains a complex leadership structure with both medical and administrative oversight[1]. The structure includes Managing Directors, Medical Directors, and Assistant Medical Directors working in coordination[1], but individual names and credentials for divisional medical directors are absent from these sources. To provide the detailed information requested—including each division's medical director, their medical specialty, and current academic or hospital faculty appointments—would require additional sources beyond those provided. A more targeted search of CPCS leadership directories or official organizational charts would be necessary to compile this comprehensive information. ## References [1] UCSF Department of Clinical Pharmacy job posting for CPCS Executive Director [2] California Poison Control System - About Us [4] America's Poison Centers Board & Staff [5] California Poison Control System - Contact Us [7] UCSF School of Pharmacy news article on CPCS
