From Animal to Man: Reuse of Patient Equipment Used on Research Animals

ISSUE: Animal researchers may request to use expensive surgical and radiological equipment designated for patients. Infection control professionals (ICPs) may be unaware of reuse due to the sensitive nature of animal research. Potential for zoonotic transmission of pathogens to patients and employees varies by species, source of animal, equipment, and infectious agents used. Limited published information exits to assist ICPs in providing infection control recommendations. PROJECT: Multidisciplinary meetings were held to develop policies for reuse of surgical and imaging equipment. Members included veterinarians, laboratory managers, investigators, infectious disease physicians, infection control, surgical processing, and central service personnel. RESULTS: Policies were developed based on type of equipment and ability to clean and sterilize. Ruminants and animals with known or suspected prion disease were excluded, as prions are difficult to destroy. Veterinarians exam all new animals for signs of disease. Equipment is divided into three categories: surgical items, ultrasound probes, and imaging. Sterilization and usage tracking is required for surgical items. Ultrasound probes are covered with barriers, cleaned, and disinfected after use. Trained handlers transport animals to Radiology in disinfected cages during off-hours. Non-rodent animals are sedated prior to transport. Handlers perform all positioning and animal contact. Barriers are used between animal and scanner; animals with airborne or droplet disease are prohibited. Researchers are encouraged to seek funding for equipment and are educated on policies. LESSONS LEANED: ICPs may be unaware of patient equipment used on animals. Researchers may “borrow” equipment without management knowledge. Institutions need policies for patient and employee protection.
