This study developed two logistic regression models to predict colic prognosis in horses. Key factors like age, heart rate, and packed cell volume were significant predictors of mortality in equine colic cases.

Area of Science:

  • Veterinary Medicine
  • Equine Health
  • Surgical Prognosis

Background:

  • Colic is a common and serious condition in horses.
  • Accurate prognosis is crucial for guiding treatment decisions and managing outcomes.
  • Predictive models can aid veterinarians in assessing the likelihood of mortality in horses with colic.

Purpose of the Study:

  • To develop and evaluate multivariable prognostic models for predicting mortality in horses with colic.
  • To identify significant clinical and biochemical parameters associated with colic prognosis.
  • To assess the predictive performance of logistic regression models in equine colic.

Main Methods:

  • Multiple logistic regression analysis was applied to data from 308 horses with colic.
  • Bivariate analysis identified significant prognostic parameters.

  • Two multivariable models were constructed using distinct case subsets.
  • Model performance was evaluated using receiver operating characteristic analysis.

    • Main Results:

    • Significant predictors included age, sex, medical/surgical classification, capillary refill time, packed cell volume, heart rate, serum bicarbonate, serum chloride, and respiratory rate.
    • Model I (n=257) had a mortality rate of 39%, including age, sex, classification, capillary refill time, packed cell volume, and heart rate.
    • Model II (n=138) had a 48% mortality rate, including age, sex, classification, capillary refill time, serum bicarbonate, serum chloride, and respiratory rate.

    Conclusions:

    • Logistic regression models can predict colic prognosis in horses.
    • Clinical parameters like heart rate and packed cell volume are important prognostic indicators.
    • Further validation in independent populations is required to confirm model generalizability and clinical utility.
