Hypothesis
Is the diagnosis of canine atopic dermatitis (CAD) in an insurance database accurate when compared to clinical records?
Conclusion
The study found that the agreement between the recorded diagnosis in the insurance database and the clinical records was acceptable, but many veterinarians did not rule out food allergies before diagnosing CAD.
Supporting Evidence
- Medical records were obtained for 335 out of 373 dogs with claims for CAD, resulting in a response rate of 89.8%.
- 97.6% of the dogs were found to have some form of allergic skin disease.
- The study highlighted that many veterinarians did not exclude food allergies before diagnosing CAD.
Takeaway
The study checked if dogs diagnosed with skin allergies really had those allergies, and it found that most did, but some might have been misdiagnosed.
Methodology
A cross-sectional study was conducted using insurance claims data and medical records from veterinarians to validate the diagnosis of CAD.
Potential Biases
Potential bias may arise from the fact that only one investigator re-classified the records.
Limitations
The study could not determine the true number of atopic dogs due to missing information on dietary trials.
Participant Demographics
The study included 335 insured Swedish dogs with a recorded diagnosis of CAD.
