Abstract
OBJECTIVE -: Significant opportunities for understanding the co-occurrence of conditions across species in coincident households remain untapped. We determined the feasibility of creating a Companion Care Registry (CCR) for analysis of health data from the University of Colorado Health (UCHealth) patients and their companion animals who received veterinary care at the geographically-adjacent Colorado State University Veterinary Teaching Hospital (CSU-VTH). MATERIALS AND METHODS -: Using a hybrid deterministic and probabilistic record linkage method, non-medical Personally Identifiable Information was securely matched to determine the total number of UCHealth patients within the HIPAA-compliant Health Data Compass Research Data Warehouse (2015-2024) who took a companion animal to the CSU-VTH (2019-2024). RESULTS -: 12,115 matches were identified, indicating 29% of CSU-VTH clients were UCHealth patients. DISCUSSION -: The overlap between CSU-VTH clients and UCHealth patients underscores the potential feasibility and utility of a CCR. CONCLUSION -: This work provides a mechanism to evaluate environmental and inter-species influences on One Health.
