Tracheobronchoscopic assessment of exercise-induced pulmonary hemorrhage in horses.

Abstract: To determine the interobserver variability of assessment of exercise-induced pulmonary hemorrhage (EIPH) during tracheobronchoscopic examination in horses. Methods: 747 Thoroughbred racehorses. Procedures-850 tracheobronchoscopic examinations were performed within 2 hours of racing for the horses. Examinations were recorded on videotape, and EIPH and its severity were assessed independently by 3 veterinarians. Concordance was determined by calculation of the Cohen weighted kappa statistic and tabulation of scores assigned by each observer. Results: Weighted kappa statistics ranged from 0.75 to 0.80. In 99.4% of observations, all observers agreed or 2 of 3 agreed and the third differed by < or = 1 grade. Conclusions: Results indicated that interobserver reliability of tracheobronchoscopic assessment of EIPH in Thoroughbred racehorses is high when the examination is conducted by experienced veterinarians. Concordance among investigators is sufficient to justify use of this grading system for further studies and clinical descriptions of EIPH.

The research study explores how consistent different veterinarians are when using tracheobronchoscopic examination to assess exercise-induced pulmonary hemorrhage (EIPH) in racehorses.

Background and Methods

  • The study’s main objective was to measure the consistency or variability (known as ‘interobserver variability’) of the assessment of exercise-induced pulmonary hemorrhage (EIPH) during a tracheobronchoscopic exam in racehorses. EIPH is a condition where horses bleed from their lungs during strenuous exercise.
  • The researchers conducted 850 tracheobronchoscopic examinations on 747 Thoroughbred racehorses. These exams consisted of visual inspections of the trachea and bronchi via a scope, which were performed within two hours of the horses having raced. The examinations were filmed for later review.

Evaluation and Findings

  • Each tracheobronchoscopic exam video was watched and evaluated by three separate veterinarians who graded the severity of EIPH. This was done to see how much their assessments agreed (known as ‘concordance’).
  • The ‘concordance’ was calculated using a statistical measure called the Cohen weighted kappa statistic. The scores assigned by each observer were also tabulated for reference.
  • The Cohen weighted kappa statistics, testing the reliability of the assessments, ranged from 0.75 to 0.80. In statistical terms, this indicates a high level of reliability amongst observer judgments.
  • Practically, the researchers found that in 99.4% of the cases, there was complete agreement amongst all the observers, or two of them agreed and the third’s score differed by one grade or less.

Conclusions

  • The results suggested that there was a high degree of reliability among the different veterinarians when they independently assessed EIPH through a tracheobronchoscopic exam in thoroughbred racehorses.
  • Due to this high concordance, the researchers concluded that it was justified to continue using this specific grading system for further studies and clinical descriptions of EIPH.
  • The study highlights the importance of internal reliability and consistency among evaluators when using visual inspection methods for diagnostics in veterinary medicine, especially in the case of EIPH.
