Consistency of faecal scoring using two canine faecal scoring systems

Area of Science:

• Veterinary Medicine
• Animal Science

Background:

• Accurate canine fecal scoring is crucial for diagnosing and managing gastrointestinal conditions.
• Existing fecal scoring systems (Purina, Waltham) aim to standardize assessment, but their inter-observer reliability is not fully understood.

Purpose of the Study:

• To evaluate the agreement in canine fecal scoring between individuals with varying experience levels (veterinarians vs. lay public).
• To compare the reliability of the Purina and Waltham fecal scoring systems.

Main Methods:

• 126 dogs' fecal samples were assessed by 3 veterinarians and 126 lay individuals within 15 minutes of defecation.
• Participants used Purina and Waltham fecal scoring charts.
• Agreement was statistically analyzed using kappa statistics and Bland-Altman methods.

Main Results:

• Veterinarian-to-veterinarian agreement was fair to substantial (kappa 0.40-0.77).
• Agreement between veterinarians and lay individuals was fair (kappa 0.38 Purina, 0.34 Waltham).
• Lay individuals showed more disagreement with veterinarians compared to other veterinarians.

Conclusions:

• Canine fecal scoring consistency improves with professional experience.
• Inconsistencies in scoring, particularly with lay individuals, may affect clinical management of canine diarrhea.
• Further research is needed to optimize fecal scoring for clinical and research applications.
