Plain-English summary
A group of dogs with breathing problems due to brachycephalic obstructive airway syndrome (BOAS) were assessed to create a new scoring system called the BRisk score, which helps predict the risk of complications during surgery. The study found that dogs with a BRisk score over 3 were significantly more likely to experience serious issues or even death after surgery. This score takes into account factors like breed, previous surgeries, and overall health. The goal is to help veterinarians better manage surgeries for these dogs and inform owners about potential risks.

Abstract
OBJECTIVE: To develop and validate a preoperative brachycephalic risk (BRisk) score that objectively and accurately predicts the risk of major complications or death in dogs undergoing corrective surgery for brachycephalic obstructive airway syndrome (BOAS). STUDY DESIGN: Retrospective multicenter cohort study. SAMPLE POPULATION: Score development n = 233 dogs, validation n = 50 dogs. METHODS: Data were collected on signalment, medical history, reason for presentation, physical examination, and preoperative diagnostic findings. The primary outcome measures included risk of major complications (requirement for postoperative oxygen support for >48 hours or postoperative temporary/permanent tracheostomy) or death within the hospitalization period. The score was developed by using data from two centers and was validated in a third center. The 10-point BRisk score was modeled on breed, history of previous surgery, concurrent procedures, body condition score, airway status, and admission rectal temperature. RESULTS: The score was associated with negative outcome (P < .0001) and discriminated well in both the construction (area under the receiver operator characteristic [AUROC] = 0.83) and validation groups (AUROC = 0.84). Dogs with scores >3 were 9.1 times more likely to have a negative outcome (95% CI = 3.9-21.2) compared with dogs with scores ≤3. CONCLUSION: The BRisk score developed from admission data in this study accurately rated the risk of negative outcome of dogs undergoing corrective surgery for BOAS. CLINICAL SIGNIFICANCE: Preoperative determination of the BRisk score may assist triage, management of owner expectations, decision making regarding intervention selection, and characterization of populations in clinical research.
