Attitudes and perceptions of Dutch veterinarians on their role in the reduction of antimicrobial use in farm animals
Introduction
The emerging antimicrobial resistance in bacteria is considered to be a major threat for public health. Farm animals are regarded as high antibiotic consumers with considerable levels of avoidable antibiotic use (U.S. Department of Health and Human Services. Centres for Disease Control and Prevention, 2013). Since antibiotic use drives resistance, there is an urgent need to reduce antibiotic use in animals to the absolute minimum that is required to safeguard animal health but still compatible with a sustainable animal production (Angulo et al., 2009, Prescott, 2008, Aarestrup et al., 2008, McEwen, 2006).
The Dutch government in 2010 imposed the livestock sectors to reduce veterinary antibiotic usage with 50% in 2013 and 70% in 2015 compared to 2009. After an initial rapid decrease in reduction of antibiotic use in farm animals (56% in 2013) there is a levelling in 2014 with 58% (MARAN, 2015). A 70% reduction will require additional fundamental changes in the behaviour of veterinarians and farmers towards the usage of antibiotics in farm animals (Speksnijder et al., 2015b). Tailored interventions directed to veterinarians to change antibiotic prescribing behaviour of veterinarians might be effective as they are key persons in reducing antibiotic use in farm animals (Prescott, 2008, Morley et al., 2005). However, only little is known about attitudes and other influences that might influence prescribing behaviour of veterinarians.
In human medicine, prescribing decisions of physicians are influenced by clinical reasoning as well as non-clinical factors which are related to personal characteristics (e.g., years in practice, extent of medical knowledge, attitudes, relationship with patients) (Akkerman et al., 2005). Knowledge of these prescribing determinants and categorization of health care providers into different target groups is extensively used for the purpose of sustainable implementation of tailored antibiotic stewardship programs and interventions (Hulscher et al., 2010a, Hulscher et al., 2010b, Kumar et al., 2003, Walker et al., 2001, Vander Stichele et al., 1996, Simpson et al., 2007).
Earlier qualitative research amongst Dutch farm animal veterinarians identified a broad variety of opinions regarding veterinary antibiotic use and ways to promote prudent use as well as determinants that influenced their prescribing behaviour (Speksnijder et al., 2015a). Further exploration of attitudes of farm animal veterinarians and their interaction with farmers in promoting animal health and subsequent categorization of farm animal veterinarians in different groups might support targeting interventions to promote prudent use of antibiotics more precisely. The purpose of this study was to explore differences in attitudes towards the use of antibiotics and reduction opportunities in farm animals and the interaction of veterinarians with farmers in improving animal health and reducing antibiotic use between categories of veterinarians.

Instrument
Based on our earlier qualitative research (Speksnijder et al., 2015a) a questionnaire was designed. Questions consisted of general descriptives, 5-point Likert scale statements (1 = completely disagree; 2 = disagree; 3 = neutral; 4 = agree; 5 = completely agree), ranking questions (ranking of items on importance) and open questions assessing attitudes, knowledge and self-reported behaviour of veterinarians regarding antibiotic use and reduction opportunities in farm animals, their interactions with
General descriptives
We received 437 questionnaires of which 377 were complete (response rate of 40% (34% complete) based on the estimated number of registered veterinarians working in farm animals). The respondents were on average 15.8 (range 1–41) years in practice and 90.2% of the respondents had received their veterinary training at Utrecht University, the Netherlands. Of the respondents, 62.9% were (co) owner of a practice while the others were working on payroll. Practice owners had on average 20.6 years of
Discussion
This study offers insights in different attitudes of different categories of farm animal veterinarians in the Netherlands towards antibiotic use and antimicrobial resistance in farm animals and their interaction with farmers herein.

2022, Journal of Dairy ScienceCitation Excerpt :Antimicrobial prescribing behavior of livestock veterinarians is dependent on multiple factors, including obligations to ease animal suffering, financial dependency on clients, risk avoidance, advisory skill limitations, producer economic limitations, lack of producer compliance, public health safety, and beliefs regarding degree of veterinary AMU contributions to AMR (Speksnijder et al., 2015a). Veterinarians consider economic drivers to be strongly correlated with producer compliance with veterinary recommendations (Speksnijder et al., 2015b; Postma et al., 2016). Higgins et al.
