ments. The IACUC, veterinary, animal care, and compliance staff may all conduct PAM, which may also serve as an educational tool.
Continuing protocol review typically consists of an annual update or review as well as the triennial review required by the PHS. The depth of such reviews varies from a cursory update to a full committee review of the entire protocol. Some institutions use the annual review as an opportunity for the investigator to submit proposed amendments for future procedures, to provide a description of any adverse or unanticipated events, and to provide updates on work progress. For the triennial review, many institutions require a complete new protocol submission and may request a progress report on the use of animals during the previous 3 years.
Both the Health Research Extension Act and the AWA require the IACUC to inspect animal care and use facilities, including sites used for animal surgeries, every 6 months. As part of a formal PAM program some institutions combine inspection of animal study sites with concurrent review of animal protocols. Based on risks to animals and their handlers, other study areas may require more or less frequent inspections. Examples of effective monitoring strategies include
examination of surgical areas, including anesthetic equipment, use of appropriate aseptic technique, and handling and use of controlled substances
review of protocol-related health and safety issues
review of anesthetic and surgical records
regular review of adverse or unexpected experimental outcomes affecting the animals
observation of laboratory practices and procedures and comparison with approved protocols.
Institutions may also consider the use of veterinary staff and/or animal health technicians to observe increased risk procedures for adverse events (e.g., novel survival surgeries, pain studies, tumor growth studies) and report their findings for review by the IACUC. The level of formality and intensity of PAM should be tailored to institutional size and complexity, and in all cases should support a culture of care focusing on the animals’ well-being (Klein and Bayne 2007). Regardless of the methods used or who conducts and coordinates the monitoring, PAM programs are more likely to succeed when the institution encourages an educational partnership with investigators (Banks and Norton 2008; Collins 2008; Dale 2008; Lowman 2008; Plante and James 2008; Van Sluyters 2008).
