Evaluation of a risk‐screening questionnaire to detect equine lung inflammation: Results of a large field study

摘要: Summary Reasons for performing study: The diagnosis of equine recurrent airway obstruction (RAO) and inflammatory disease (IAD) is based on clinical signs increased cell percentages in the bronchoalveolar lavage (BAL) fluid. Since a BAL an invasive procedure, risk-screening questionnaire (RSQ) would be valuable screening tool lung inflammation. Objective: To evaluate accuracy RSQ to detect lower inflammation (LAI) large population horses. Methods: A standardised was performed field 167 horses Alberta, Canada. Horses were separated into 3 categories: 1) normal; 2) mild moderate LAI (MLAI), 3) severe (SLAI). horse owners asked complete RSQ. scores compared results determine likelihood having MLAI, SLAI or no LAI. Results: Based cytology, 28 (17%) normal 139 (83%) abnormal, with 110 (66%) showing MLAI 29 SLAI. had mean score 0.95 0.70, respectively, 0.60 horses. showed more than sensitivity negative predictive values detecting using cut-off 0.87, excellent at 0.90 (95%CI 0.73–0.98) 0.96 0.82–1.00). Questions typically found RAO cases differed significantly between those normal. Conclusions: Prevalence high this population. Although did not allow differentiating from it has therefore good
