Primate Information Retrieval Record System (PIRS): The Primate Information Retrieval System (PIRS) is a computerized database system established in 1975 to maintain the experimental, clinical, pathologic and demographic data for all nonhuman primates in our colonies, past and present. PIRS allows storage, processing and retrieval of information concerning an individual animal or a group of animals. The system contains vital information consisting of over 2,500,000 records on approximately 13,000 animals presently and formerly at the facility. Access to the system is available to all on-site users and authorized staff members. Users can request the transfer of selected PIRS data into Excel and/or RS/1 for analyses and graphics. All data is up to date and available for on-line access daily via a web-interface.
The software used in the management of this data is ORACLE. It has been used by the DSU over the last 20 years to coordinate colony management data and some research data. This software can program data entry screens and perform range checks upon entry. RS/1 provides a built-in interface to ORACLE to allow easy transfer and access to data. Data entry and correction procedures are consistent, regardless of which software package is used during DSU processing.
Collection and storage of data on nonhuman primates begin with the arrival of animals into our colonies either through acquisition from outside sources or birth at our institution. All important events from that time on are recorded such as origin, birth date, parentage, location, diet, illnesses, diagnostic tests, therapeutic interventions, experimental analyses and experimental manipulations. Data are categorized as informational, clinical, research or surveillance. Data collection continues until the animal is transferred to another institution or dies. Results of necropsy examinations on all primates are also stored in our computerized record system.
