Background:
Misconceptions can be defined as 'false, persistent beliefs' or 'inaccurate, prior knowledge' and can influence decision-making.
Objectives:
To investigate the impact of evidence-based information on UK horse owners' decision-making for colic.
Study Design:
Mixed-methods cross-sectional study.
Methods:
An online survey was distributed to UK horse owners, with four sections: owner demographics; views on decision-making and referral to an equine hospital facility for colic; current knowledge and approach to colic; impact of evidence-based information (including evidence on recognising and responding to colic, and colic surgery survival and outcome data) on decision-making. Statistical analysis was performed using Kendall's tau for continuous variables and Chi-squared testing for categorical variables. Multivariable analysis was performed using a generalised linear model with binomial distribution (logistic regression), with p < 0.05 for model fit. Content analysis was used for free-text answers.
Results:
In total, 1544 participants met inclusion criteria. Owners were more likely to agree to referral if their horse was insured (p < 0.001, 95% confidence interval [CI]: 1.86-2.93), and less likely if their horse was older (p < 0.001, CI: 0.90-0.94) or they felt pressure (p < 0.001, CI: 0.44-0.70). Pressure to refer was mainly from veterinary professionals (66%, 367/549) or peers (20%, 110/549). Many participants were unaware of how quickly irreversible intestinal damage could occur (58%, 903/1544), costs of colic surgery and UK insurance cover limits (63%, 966/1544), post-operative survival rates for geriatric vs. non-geriatric horses (65%; 996/1544), or prognosis for return to work following colic surgery (68%, 1052/1544). Sharing evidence-based information had limited impact on decision-making. Free text response analysis identified previous experience of colic, anecdotal information, finances and peer pressures as barriers to change.
Main Limitations:
Potential for response bias, UK participants only.
Conclusions:
Misconceptions around colic were common, with many horse owners reluctant to change their approach after evidence-based information. Intent to pursue referral was less likely with increasing horse age and perceived pressure to refer.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
