Determination of a gravity and shock score for prognosis in equine surgical colic.

The research article explores a retrospective study of 200 surgical colic cases in horses and the development of a gravity score (GS) and shock score (SS) to determine the prognosis of the condition. Clinically relevant parameters were used in creating the scores, and the data showed a strong relationship between the scores and survival rate.

Background and Methodology of the Study

• The research was a retrospective study meaning the data had already been collected and was analyzed afterward. In this case, the researchers evaluated 200 surgical colic cases in horses.
• The objective of the study was to develop a scoring system based on clinically relevant parameters to predict the prognosis of surgical colic in horses. Two such scores were developed: a gravity score (GS) and a shock score (SS).
• The gravity score was based on four clinical parameters: rectal palpation, borborygmi (gut sounds), abdominal distension, and pain. The shock score was based on six parameters that were not disclosed in the abstract.

Results and Statistical Analysis

• The overall survival rate for the 200 surgical colic cases was 54%.
• Statistical analysis revealed a significant difference in survival rates among the different categories of the GS and the SS, suggesting a strong relationship between these scores and the outcome of the condition.
• A multivariate logistic regression model was used to quantify the relationship between the GS and the prognosis. The model showed that horses with a GS of 3 (presumably the worst category) were 10.6 times more likely to die than those with a GS of 1 (presumably the best category).
• A combined model using both the gravity and shock scores was also created. The odds ratio of 7.1 for GS 3 versus GS 1 implies that horses with a gravity score of 3 were 7.1 times more likely to die than those with a gravity score of 1. Similarly, the odds ratio of 7.2 for SS 3 versus SS 1 suggests horses with a shock score of 3 were 7.2 times more likely to die than those with a shock score of 1.

Conclusion

• The results of the research suggest that the gravity and shock scores could be valuable tools in evaluating the prognosis in equine surgical colic cases, as they showed a strong predictive relationship with the survival rate. This could aid veterinarians in making informed treatment decisions.
