Factors associated with survival to hospital discharge following endoscopic treatment for synovial sepsis in 214 horses.
Abstract: To determine risk factors involved in survival to hospital discharge of cases of synovial sepsis. Objective: Investigate pre-, intra- and post operative factors involved in short-term survival of horses undergoing endoscopic treatment for synovial sepsis. Methods: Retrospective case series. Methods: Clinical data were obtained for horses (>6 months old) undergoing endoscopic surgery as part of management for synovial sepsis over a 7-year period in a single hospital population. Descriptive data were generated for pre-, intra- and post operative variables. Multivariable logistic regression analysis was used to develop 3 models related to presurgical, surgical and post surgical stages of management with outcome defined as survival to hospital discharge. Results: Two hundred and fourteen horses were included. In Model 1 (preoperative variables), increased preoperative synovial fluid total protein (TP) was associated with nonsurvival (OR 0.88, 95% CI 0.83-0.94, P<0.001) whereas the presence of a wound on admission was associated with survival (OR 4.75, 95% CI 1.21-18.65, P = 0.02). Model 2 (intraoperative variables) revealed that factors associated with decreased survival were anaesthetic induction outside of normal working hours (OR 0.36, 95% CI 0.15-0.88 P = 0.02) and presence of moderate/severe synovial inflammation at surgery (OR 0.28, 95% CI 0.12-0.67, P = 0.004). Model 3 (post operative variables) showed that increased post operative synovial fluid TP (OR 0.94, 95% CI 0.90-0.98, P = 0.013) and undertaking more than one endoscopic surgery for treatment (OR 0.19, 95% CI 0.05-0.70, P = 0.005) were associated with nonsurvival. Cut-off values for predicting survival were 55-60 g/l for preoperative and 50-55 g/l for post operative TP measurements. Conclusions: This study has identified factors associated with altered likelihood of survival to hospital discharge following endoscopic surgery for synovial sepsis. Prognosis for survival to hospital discharge can be based on evidence from this study at the key stages of management of horses with synovial sepsis.

The research paper explores the risk factors associated with the survival of horses discharged from hospital following endoscopic treatment for synovial sepsis. Using a model that considers pre-, intra- and post-operative stages, the study identifies key outcome determinants like preoperative synovial fluid protein level, anesthetic induction time, presence of wound, and the extent of synovial inflammation.
Research Methodology
- The study is based on the clinical data obtained from horses that were over 6 months old and underwent endoscopic surgery to treat synovial sepsis in a single hospital over a 7-year period.
- Descriptive data were generated for various preoperative, intraoperative, and postoperative variables.
- Using multivariable logistic regression analysis, three separate models were created, representing presurgical, surgical, and post-surgical stages of management. Survival to hospital discharge was defined as the outcome.
Results and Findings
- The study included 214 horses. In Model 1 focusing on preoperative variables, an increased preoperative synovial fluid total protein (TP) level was associated with a lower survival rate (OR 0.88, 95% CI 0.83-0.94), while the presence of a wound on admission was associated with survival (OR 4.75, 95% CI 1.21-18.65).
- In the second model revolving around intraoperative variables, anesthetic induction outside of normal working hours (OR 0.36, 95% CI 0.15-0.88) and the presence of moderate/severe synovial inflammation at the time of surgery (OR 0.28, 95% CI 0.12-0.67) were associated with decreased likelihood of survival.
- The third model concerned with post-operative variables showed that an increased post-operative synovial fluid TP (OR 0.94, 95% CI 0.90-0.98) and undergoing more than one endoscopic surgery for treatment (OR 0.19, 95% CI 0.05-0.70) were associated with nonsurvival.
- Predictive cut-off values for survival were 55-60 g/l for preoperative and 50-55 g/l for post-operative TP measurements.
Conclusions
- The research identified that specific factors at various stages of management of horses with synovial sepsis can alter the likelihood of survival to hospital discharge after endoscopic surgery.
- The prognosis for survival to hospital discharge can be based on evidence from this research, providing valuable assistance in veterinary care and treatment planning for horses with synovial sepsis.
