Question

The California Poison Control System (CPCS) functions as a statewide network dedicated to providing expert treatment advice for poison exposures. Identify the specific university school that holds the contract to administratively manage this entire system. Furthermore, list the four distinct academic medical center or hospital locations where the CPCS operating divisions are physically housed.

Answer length: 150-250 words.

Depth checklist

Correctly identifies the single administrative managing entity
Correctly identifies all four geographic divisions/locations of the system

Width checklist

Administrative Body: UCSF School of Pharmacy
Division 1 Location: UC Davis Medical Center (Sacramento)
Division 2 Location: Zuckerberg San Francisco General Hospital (San Francisco)
Division 3 Location: Valley Children’s Hospital (Madera/Fresno)
Division 4 Location: UC San Diego Medical Center (San Diego)

Examiner rationale

The question uses Deep Logic by requiring the identification of the specific administrative structure behind the named entity (CPCS). It enforces Wide Aggregation by requiring the retrieval of four distinct physical locations (divisions) that make up the system, which are often listed in 'About Us' or 'Contact' sections rather than a single summary sentence.

Score 1 - 0

Both agents correctly identify the UCSF School of Pharmacy as the administrative manager. Agent A is the winner because it correctly identifies the four geographic regions of the system's divisions (San Francisco, Sacramento, Fresno, San Diego). Although Agent A cites the wrong specific hospitals for the Fresno and San Diego divisions (listing CRMC and Rady Children's instead of Valley Children's and UCSD Medical Center), it captures the correct statewide structure. Agent B is the loser because it hallucinates a division in Los Angeles (which does not exist) and omits the Fresno/Madera division entirely, fundamentally misrepresenting the network's coverage. Agent B also misidentifies the San Francisco hospital location.

The California Poison Control System (CPCS) is administratively managed under contract by the **School of Pharmacy at the University of California, San Francisco (UCSF School of Pharmacy)**, which serves as the statewide coordinating institution for the program.[1][2] CPCS operations are organized into four geographically based divisions, each housed at a separate academic medical center or hospital: 1. **San Francisco Division** – located at **Zuckerberg San Francisco General Hospital and Trauma Center**, affiliated with UCSF.[1][3] 2. **Sacramento Division** – housed at **UC Davis Medical Center** in Sacramento, part of the UC Davis School of Medicine health system.[1][3] 3. **Fresno/Madera (Central) Division** – based at **Community Regional Medical Center** in Fresno, a major teaching hospital for UCSF Fresno.[1][3] 4. **San Diego Division** – located at **Rady Children’s Hospital–San Diego**, an academic pediatric institution affiliated with UC San Diego.[1][3] Together, these four sites deliver the 24/7 statewide poison consultation services while administrative oversight, contracting, data coordination, and statewide program management are centralized within the UCSF School of Pharmacy.[1][2][3] ## References [1] California Poison Control System – “About CPCS” / organizational overview [2] UCSF School of Pharmacy – program description and contract role with CPCS [3] CPCS regional center location information and affiliated hospitals

The University of California, San Francisco (UCSF) School of Pharmacy holds the contract to administratively manage the entire California Poison Control System (CPCS) [1][2]. This statewide poison control network has been administered by UCSF since 1997, when California consolidated its regional poison centers into a single unified system [2]. The CPCS operates through four distinct division locations strategically positioned across California to provide comprehensive coverage. These physical operating divisions are housed at: 1. **UC San Francisco Medical Center** - serving the San Francisco Bay Area and northern California regions [1][3] 2. **UC Davis Medical Center in Sacramento** - covering the Central Valley and northeastern California areas [2][3] 3. **UC San Diego Medical Center** - managing poison exposure calls from San Diego County and surrounding southern regions [1][3] 4. **Children's Hospital Los Angeles** - serving Los Angeles County and adjacent southern California territories [2][3] These four divisions function as an integrated network, handling over 300,000 calls annually through the toll-free hotline 1-800-222-1222 [3]. Each location is staffed by specially trained pharmacists, physicians, and nurses who provide 24/7 expert consultation for poison exposures and overdoses. The system serves all 58 California counties, offering multilingual services to healthcare professionals and the public, while also conducting surveillance, education, and research activities related to poisoning prevention and treatment [1][2]. ## References [1] California Poison Control System Official Website - www.calpoison.org [2] UCSF School of Pharmacy - CPCS Administration Overview [3] California Department of Public Health - Poison Control Services
