Factors influencing the behaviour and perceptions of Australian veterinarians towards antibiotic use and antimicrobial resistance.

ABSTRACT: Antimicrobial resistance (AMR) is a global crisis with impacts on the future health and welfare of humans and animals. Determining key factors that influence veterinarians' antimicrobial prescribing behaviours can bridge the gap between prescribing guidelines and clinical usage. Veterinarians practicing in Australia were surveyed on their frequency in prescribing different antibiotics; factors influencing their antibiotic prescribing behaviours; and their perceptions of current drivers of AMR. Antibiotics were prescribed in a third of consultations with key differences in the frequency of use of specific antibiotics by small companion animal (SCA), equine and livestock veterinarians, which broadly aligned with antibiotic registration restrictions in Australia. SCA veterinarians reported prescribing broad-spectrum antibiotics of higher importance to human health more frequently than livestock veterinarians. Factors that were reported as 'strong' or 'moderate' barriers to appropriate antibiotic prescribing were the 1) cost of culture and susceptibility testing and 2) lack of access to rapid and affordable diagnostic tests. Fear of losing clients, colleague pressure, and lack of their own understanding about antibiotics were considered to be 'no' or 'somewhat' of a barrier to appropriate prescribing by respondents. SCA veterinarians placed greater importance on the contribution of antibiotic use in livestock to AMR, than antibiotic use in companion animals. Despite reporting use of fewer, mostly narrow spectrum antibiotics of lower importance to human and animal health, livestock veterinarians were generally more aware of their potential contribution to AMR. This study provides insights into the similarities and differences in SCA, equine and livestock veterinarians practicing in Australia and informs sector-specific strategies to improve antimicrobial stewardship.

Project description:BackgroundThe emergence of antimicrobial resistance is a growing human and animal health concern around the world. When a number of studies have emphasized the Knowledge, Attitude and Practice (KAP) regarding antibiotic use and resistance in humans, little attention has been paid to the veterinary sector. The aim of this study was to understand the KAP towards antibiotic use and resistance among veterinarians in Bangladesh.MethodsA cross-sectional online based questionnaire survey was conducted from August to September 2020 among the registered veterinary practitioners. A self-administered Google form questionnaire consisting of 45 questions on knowledge, attitude and practice regarding antibiotic use and resistance was used. For statistical significance test we used Chi-square or Fisher's Exact test and logistic regression for factor analysis.ResultsA total of 208 registered veterinarians participated in this study. The study involved a majority of male participants, constituting 85.1%, while 54.8% of the participants held a Masters degree. Around 52% of the veterinarians were poultry practitioners. All respondents were familiar with antimicrobials. The participants (91.4%) knew that antibiotics cannot cure viral infections, while 97.6% believed that frequent antibiotic prescriptions rendered them less effective. Participants claimed that only they were eligible to prescribe drugs for the treatment of animals, and around 80% disagreed with adding antibiotics with feed/water as a growth promoter in livestock. Of the total participants, 87% believed that a local antimicrobial guideline would be more effective than an international one. A multivariable analysis revealed that male veterinarians have 2.37 times higher knowledge regarding antimicrobial use (AMU) and antimicrobial resistance (AMR) (OR = 2.37, CI = 1.01-5.59, p = 0.05). Veterinarians engaged in government services demonstrated a 2.59 times more favorable attitude towards AMU and AMR (OR = 2.59, CI = 0.99-6.73, p = 0.05). Additionally, respondents aged 31-35 were 0.45 times more likely to exhibit good practices (OR = 0.45, CI = 0.2-1.00, p = 0.05). However, gaps in practices were highlighted in our study, suggesting training deficiencies.ConclusionThe present study, for the first time conducted in Bangladesh, dictates that future interventions like academic courses, workshops, and seminars on antibiotic usage and resistance are needed to facilitate the knowledge, behavior and practice of veterinarians with regard to the rational use of antibiotics.

Project description:Antimicrobial resistance (AMR) is widely perceived as a threat to human and animal health and a significant One Health issue with extensive and complex factors contributing to its occurrence and spread. Previous studies have surveyed human and animal health professionals to determine their perceptions regarding AMR and antimicrobial use (AMU). There are limited studies exploring the understanding of veterinary students despite their critical role as future antimicrobial prescribers. A cross-sectional survey was administered to an entire cohort of Doctor of Veterinary Medicine Year 2 (DVM2) students (n = 136) to investigate their knowledge and perceptions regarding AMR and AMU prior to formal education on this issue. Ninety students (66.2% of the cohort) completed the survey. There was overwhelming agreement regarding the immediacy of the problem, with 84.4% of students indicating that 'We must take action on AMR'. Despite more than 94.4% of students correctly defining AMR, specific knowledge regarding AMR impact, contributory causes to AMR and strategies to solve the challenge of AMR was variable. Most students perceived livestock producers to have a significant role in the perpetuation of AMR due to AMU for prophylaxis (71.1% substantial/moderate contribution) and treatment (56.7% substantial/moderate contribution). Over a third of respondents (37.8%) were unsure if AMR could spread from animals to humans. Respondents perceived that various groups (dentists, doctors, veterinarians, professional organisations) are all important in ameliorating the issue of AMR. The implementation of restrictive measures to reduce veterinary prescription of antimicrobials was viewed as less important than strategies involving education, hygiene, surveillance, and guideline development/availability. To encourage the development of good antimicrobial stewardship (AMS) practices, professional veterinary education needs to foster an understanding of the scientific, behavioural and social issues that contribute to AMR and inappropriate AMU, as well as prescribers' personal contribution to AMR perpetuation and amelioration.

Project description:BackgroundInappropriate antimicrobial use (AMU) is a global concern. Opinions of veterinarians regarding AMU and its role in the development of antimicrobial resistance (AMR) may influence their prescription practices. It is important to understand these opinions, prescription practices and their potential impact on the development of AMR in order to guide efforts to curb the problem. Therefore, the objective of this study was to investigate the antimicrobial prescription practices and opinions of veterinarians in Kentucky regarding AMU and AMR.MethodsThis cross-sectional study used a 30-question survey questionnaire administered to veterinarians who were members of the Kentucky Veterinary Medical Association. Survey responses from 101 participants were included in the study. Descriptive statistics were computed and associations between categorical variables assessed using Chi-square or Fisher's exact tests. Firth logistic models were used to investigate predictors of "Compliance with prescription policies" and "Cost of antimicrobial affects prescription decisions".ResultsAlmost all (93%) respondents indicated that improper AMU contributed to selection for AMR. A total of 52% of the respondents believed that antimicrobials were appropriately prescribed, while the remaining 48% believed that antimicrobials were inappropriately prescribed. Significant predictors of compliance with prescription policies were availability of prescription policy at the veterinary facility (Odds Ratio (OR) = 4.2; p<0.001) and over-prescription (OR = 0.35; p = 0.025). Similarly, significant predictors of cost of antimicrobials affecting prescription decisions were lack of post-graduate training (OR = 8.3; p = 0.008) and practice type, with large animal practices having significantly lower odds of the outcome (OR = 0.09; p = 0.004) than small animal practices.ConclusionMost veterinarians indicated that improper AMU contributed to selection for AMR. Since the odds of compliance with prescription policies were 4-times higher among veterinarians working at facilities that had prescription policies compared to those at facilities that didn't, more veterinary facilities should be encouraged to adopt prescription policies to help improve compliance and reduce AMR. Veterinarians would also benefit from continued professional education to help improve prescription practices, antimicrobial stewardship and curb AMR.

Project description:Veterinarians are the main source of information for farmers regarding the responsible use of antibiotics in farm animals and how to reduce the risk of antibiotic resistance. Consequently, understanding how veterinarians perceive their clients' and colleagues' antibiotic use and their own beliefs about the development of antibiotic resistance is essential to determining areas in which antibiotic use practices can be improved to minimize the emergence of antibiotic resistance. An international cross-sectional study was carried out using a questionnaire designed to elucidate perceptions, attitudes, and concerns of dairy veterinarians regarding antibiotic use and the emergence of antibiotic resistance in dairy farming. The questionnaire was initially administered to veterinarians attending the International Bovine Mastitis Conference in Milano, Italy, 2018, followed by veterinarian members of the National Mastitis Council, and all conference registrants. A total of 71 participants from 21 countries participated in the survey, the majority were from the United States and member countries of the European Union. Logistic regression analysis was conducted to identify predictors of veterinarians' level of concern about the development of antibiotic resistance on their clients' farms. Associations were described with odds ratios (ORs) and the associated 95 % confidence intervals (95 % CIs). Free text responses where participants shared their views on the reason for overprescribing antibiotics by veterinarians were analyzed using thematic analysis. Participants perceived that nearly half of their clients overuse or inappropriately use antibiotics, and nearly half of their colleagues overprescribe or inappropriately prescribe antibiotics. After controlling for other factors, the odds of veterinarians being concerned about antibiotic resistance on dairy farms they served decreased by a factor of 0.91 for each additional year of participants' experience working with dairy cattle (OR = 0.91, 95 % CI = 0.84-0.99). Participants concerned about antibiotic resistance on clients' dairy farms were also more likely to consider better adherence to drug labelling as important for reducing farmers' antibiotic use (OR = 6.86, 95 % CI = 1.21-38.93). Thematic analysis revealed four themes surrounding the perceived reasons for veterinarians' overprescribing of antibiotics: (i) knowledge, (ii) attitudes, (iii) barriers, and (iv) rules and regulations. The study findings will aid in the development of strategies to improve antibiotic use in dairy farming and educational initiatives looking to enhance the communication between veterinarians and farmers about judicious use of antibiotics.
