Project description:Resistance to antimicrobials is one of the biggest challenges worldwide for public health. A key strategy for tackling this is ensuring judicious use of antimicrobials in human and veterinary medicine. Whilst there are many studies in human medicine investigating prescribing behaviour of doctors, there is limited work to understand what factors influence veterinarian prescribing behaviour. Veterinarians often prescribe antimicrobials to sheep and beef farmers in contexts other than at a clinical consultation, and decision-making behind this has not been explored. The aim of this study was to measure, for the first time, the influence of factors from social theories on veterinarians' decision to prescribe antimicrobials to sheep and beef farmers without a clinical consultation, using a factorial survey approach. Respondents were presented with eight vignette scenarios, where a farmer asks for antimicrobials at the veterinary practice. Seven factors, identified from constructs of social theories, were included in the vignettes. Random intercept and random slope models were built to estimate the effects of the vignette factors and vet characteristics on the respondents' willingness to prescribe ratings. A total of 306 surveys were completed. The vignette factors: case type, farmer relationship, other veterinarians in practice, time pressure, habit, willingness to pay, and confidence in the farmer, were significant in the decision to prescribe. Confidence in the farmer was the most influential vignette variable, and was included as a random slope effect. Respondent variables with significant influence on the decision to prescribe were agreeableness personality score, region of veterinary practice, and presence of a small animal department. These influential factors could be considered to target interventions in beef and sheep farm animal veterinary practice for improved antimicrobial stewardship.
Project description:Inappropriate antimicrobial prescribing contributes to the global spread of antimicrobial resistance. The pending weekend with changed availability of general practitioners (GP) and increased patient concern may increase the intention to prescribe antimicrobials. The aim of this study is to analyse variation in antimicrobial prescribing between weekdays and weekend in Irish general practice. All prescribing data over a 15 month period was obtained from the 30 practices participating in the Supporting the Improvement and Management of Prescribing for urinary tract infection (SIMPle) study. Antimicrobials were classified using anatomical therapeutic chemical classification code guidelines. Prescribing of antimicrobials per total number of prescriptions was compared between weekdays (Monday to Thursday) and the weekend (Friday to Sunday). Antimicrobials were generally more often prescribed during weekends; the antimicrobial prescribing rate was greater by 9.2 % on Friday compared to average prescribing on other weekdays (21.4 vs. 19.6 %). The chance of an antimicrobial prescription was 1.07 (95 % CI 1.04-1.10) higher on weekend days compared to weekdays. This was reflected in increased prescriptions for ampicillin, co-amoxiclav, nitrofurantoin, quinolones and macrolides. However, if antimicrobials were prescribed, no significant differences were observed between weekdays and weekend among the different classes of antimicrobials. GPs prescribe relatively more antimicrobials during the weekend compared to weekdays. However, the patterns of antimicrobial prescribing did not differ according to the day of prescription. Trial Registration The intervention was registered with ClinicalTrials.gov on 26 July 2013, ID number NCT01913860.
Project description:Background: There has been very little previous research in Ireland on the opinions of farmers regarding dairy beef integration. The need for increased dairy beef integration has assumed a greater importance in Ireland in recent years due to a rapid expansion in dairy production, and associated increase in numbers of male dairy calves born on Irish farms. The objective of this study was to explore beef farmers' views on a broad range of issues related to dairy beef integration, using a survey methodology. The survey was distributed to approximately 4,250 beef farmers via email and 1,203 participated in the study. Results: The sample was composed almost entirely of beef farmers, although a very small proportion also had a dairy enterprise on their farm. Eighty percent of the farmers were concerned with the increase in the number of male dairy calves in recent years. Fifty seven percent of farmers responded that they were not willing to rear dairy bred calves for beef. Limousin, Aberdeen Angus and Hereford were the breeds farmers would be most willing to rear for beef. Good health, breed, and conformation were ranked as the main factors calf rearers consider when buying calves. Expectation of poor profit margin, expectation of poor-quality calves, and price volatility/market uncertainty were the top ranked factors dissuading farmers from rearing dairy calves for beef. The main themes arising from the qualitative question related to beef price/ability to make a profit, breed, and calf quality. Conclusions: While it is concerning that the majority of respondents expressed an unwillingness to rear dairy bred calves for beef, approximately a quarter of beef farmers indicated a willingness to rear beef-sired dairy calves for beef. In the qualitative responses, farmers described how their concerns about calf quality and their ability to make a profit from dairy bred calves would make it difficult for them to rear these calves for beef. Future strategy will have to consider how these challenges can be overcome and the issues of who bears the risks and costs associated with greater integration will have to be carefully considered.
Project description:An unusual inflammation of the pinna has been reported to occur in some sheep farmers at the time of lambing.To explore the prevalence of this disorder and its possible causal associations.While on attachment to sheep farms during lambing, veterinary students used a standardized questionnaire to interview a sample of farmers about their work and about symptoms of skin inflammation in their hands, face and ears.Interviews were completed by 76 (67%) of the farmers approached. Among 74 farmers who had carried out lambing, 3 (4%, 95% CI 1-11%) had experienced temporally related ear symptoms, all on multiple occasions. No farmers with ear symptoms had ever been involved in calving or farrowing, and no ear symptoms were reported in relation to shearing or dipping sheep. There was also an excess of hand symptoms related to lambing outdoors (24% of those who had done such work) and indoors (also 24%) compared with other farming activities.Our findings suggest that temporally related ear inflammation occurs in at least 1% of farmers who carry out lambing but not in association with the other farming activities investigated. Lambing appears to be associated also with hand inflammation, but the pathology may differ from that in the pinna.
Project description:BackgroundHIV clinicians are uniquely positioned to treat their patients with opioid use disorder using buprenorphine to prevent overdose death. The Prescribe to Save Lives (PtSL) study aimed to increase HIV clinicians' buprenorphine prescribing via an overdose prevention intervention.MethodsThe quasi-experimental stepped-wedge study enrolled 22 Ryan White-funded HIV clinics and delivered a peer-to-peer training to clinicians with follow-up academic detailing that included overdose prevention education and introduced buprenorphine prescribing. Site-aggregated electronic medical record (EMR) data measured with the change in X-waivered clinicians and patients prescribed buprenorphine. Clinicians completed surveys preintervention and at 6- and 12-month postintervention that assessed buprenorphine training, prescribing, and attitudes. Analyses applied generalized estimating equation models, adjusting for time and clustering of repeated measures among individuals and sites.ResultsNineteen sites provided EMR prescribing data, and 122 clinicians returned surveys. Of the total patients with HIV across all sites, EMR data showed 0.38% were prescribed buprenorphine pre-intervention and 0.52% were prescribed buprenorphine postintervention. The intervention increased completion of a buprenorphine training course (adjusted odds ratio 2.54, 95% confidence interval: 1.38 to 4.68, P = 0.003) and obtaining an X-waiver (adjusted odds ratio 2.11, 95% confidence interval: 1.12 to 3.95, P = 0.02). There were nonsignificant increases at the clinic level, as well.ConclusionsAlthough the PtSL intervention resulted in increases in buprenorphine training and prescriber certification, there was no meaningful increase in buprenorphine prescribing. Engaging and teaching HIV clinicians about overdose and naloxone rescue may facilitate training in buprenorphine prescribing but will not result in more treatment with buprenorphine without additional interventions.
Project description:The timely implementation of antimicrobial stewardship interventions could delay or prevent the development of higher levels of antimicrobial resistance in the future. In food-producing animals in Australia, high-importance antimicrobials, as rated by the Australian Strategic and Technical Advisory Group (ASTAG), include virginiamycin and third-generation cephalosporins (in individual pigs or cattle). The use of high-importance antimicrobials in companion animals is more widespread and less regulated. There is no national antimicrobial use surveillance system for animals in Australia. Consequently, there is a gap in the knowledge about reasonable use across all sectors of veterinary practice. This study explored attitudes towards the use in veterinary medicine of antimicrobials with high importance to human health, and determined levels of agreement about the introduction of restrictions or other conditions on this use. An online survey was distributed via social media and email from June to December 2020 to veterinarians working in Australia. Of the 278 respondents working in clinical practice, 49% had heard of the ASTAG rating system, and 22% used a traffic light system for antimicrobial importance in their practice. Overall, 61% of participants disagreed that veterinarians should be able to prescribe high-importance antimicrobials without restrictions. If there were to be restrictions, there was most agreement amongst all respondents for only restricting high-importance antimicrobials (73%). There is a need for education, guidance, and practical support for veterinarians for prescribing high-importance antimicrobials alongside any restrictions.
Project description:This study aimed to describe the perception of veterinarians who work with commercial laying hens in the state of Rio Grande do Sul, Brazil, regarding the use of antibiotics and their possible impacts on animal, human, and environmental health. A descriptive epidemiological study was carried out through face-to-face or web conferencing interviews with the veterinarians that provide technical assistance at commercial laying hen operations. A standardized and structured questionnaire was developed based on the literature and expert opinion, which contained 1 opened and 40 closed questions. Conventional non-probabilistic sampling was used, based on an initial list of 15 veterinarians registered in the Poultry Production Association of Rio Grande do Sul, followed by the snowball technique. The acquisition of 26 contacts of veterinarians was accomplished, and 16 were interviewed. Through the answers obtained it was possible to verify that the interviewees' understanding regarding both the antibiotic resistance impact and the decision-making about the use of antibiotics seem to be linked to their practical experiences. Besides that, according to the veterinarians, farmers can acquire and administer the antimicrobials on their farms. Moreover, both farm storage and administration of lower doses of antibiotics than the recommended one could be contributing factors to resistant bacteria selection. Furthermore, controversially, the professionals believed that resistant bacteria can be transmitted to humans from eggs, but they said that there are no bacteria in eggs. Therefore, the veterinarians´ practices can be improved considering national and international guidelines on antimicrobial resistance to minimize the development of resistance. Finally, it is expected that the present results will contribute to a more complex discussion about antimicrobial resistance, helping to formulate public policies in the egg production industry.
Project description:The aims of this study were to investigate the role of the veterinarian characteristics (e.g., age, gender, self-estimation, use of the internet), and their attitudes concerning animal owners seeking self-information. A particular focus was laid on any association between shared decision making (SDM), age and gender. In an online survey, 527 German veterinarians were asked about their attitude regarding SDM principles and their experiences with self-informed animal owners. The factors associated with veterinarians' perception of SDM were investigated in a multivariable linear regression model. A recently published structural equation model consolidated the application of SDM, empathic behavior, and veterinarians' evaluation of self-education as latent factors. Interconnected questionnaire items were processed using an exploratory factor analysis to 11 interpretable factors. Veterinarians who assumed therapy failure was associated with themselves had significantly higher rates of SDM (p = 0.002). In contrast, SDM was significantly lower (p = 0.002) if they assumed that therapy failure was due to the animal's owners. SDM was negatively associated with the perceived quality of the pet owners' self-information (p < 0.001) and if skepticism was perceived as the reason for seeking the self-information (p = 0.001). Veterinarians who advised against self-information (p = 0.006) and those who assumed that self-information of animal owners goes along with uncertainty (p = 0.001) had low SDM values (p = 0.006). Asking the animal owner for self-information (p = 0.001), and recommendations of good information sources (p = 0.022) were positively associated with SDM. Looking at the influence of age and gender on the application of SDM, older people and males rated higher. However, the evaluation of the latent factor SDM was based on the self-estimation of the participants. Assuming that younger women were less self-confident, we cannot exclude that young female participants self-evaluated their SDM skills lower than older male participants, although both groups would objectively have the same SDM level. Practitioners who have a positive attitude toward animal owners, who enjoy contact with animal owners and welcome their interest in further (self-)information, show empathic behavior, and have a positive attitude toward SDM are more likely to have better veterinarian-animal owner-relationships.
Project description:Antimicrobial resistance (AMR) is an important challenge in public health. Ensuring rational antimicrobial use (AMU) on farms is one of the key components of antimicrobial stewardship. We aimed to describe a sample of Canadian dairy farmers’ personal factors for AMUand their AMR risk perception, and to associate these factors with their attitude toward promotion of prudent AMU. We distributed an online survey among dairy farmers in Ontario and Atlantic Canada (New Brunswick, Nova Scotia, and Prince Edward Island). The questionnaire was designed to solicit information on dairy farmers’ AMU decision-making process, attitudes toward AMU reduction, awareness of AMR, and individual values. We performed a factor analysis on 15 statements related to AMR awareness and AMU reduction and used a logistic regression model to identify variables associated with the probability of disagreeing with the need to increase promotion of responsible AMU in the dairy industry. Respondents’ (n = 193) previous experience was the main reason to select an antimicrobial treatment for their cattle. We identified four groups of factors related to knowledge, risk perception, and emotional states among respondents. To the question “Should there be more initiatives to promote responsible use of antibiotics in the dairy industry?” 23% of respondents answered no, which was associated in a logistic regression model with being a farm owner, having a tie-stall barn, and considering their own experience as the most important factor in selecting antimicrobial treatments. The score for the conservation value dimension and score for a factor described as sense of responsibility when using antimicrobials were also retained in the final model. Our results indicate that tailored strategies to promote prudent AMU on dairy farms may be preferable to a generic strategy because there are individual differences in attitudes, values, and AMR awareness that shape AMR risk perception and willingness to modify current AMU practices.
Project description:Methicillin-resistant Staphylococcus aureus (MRSA) has emerged over the last few decades as a One Health problem with an increasing prevalence in various animal species. The most notable animals are pigs, as asymptomatic carriers, and horses, where there is often an association with infections. The current study looked at the course of MRSA prevalence in Swiss livestock since 2009, with a special focus on pigs, followed by screening of veterinarians and farmers. Livestock isolates were obtained from the Swiss monitoring program and then characterized by spa typing. Concentrating on the year 2017, we analyzed the prevalence of MRSA in Swiss veterinarians and farmers, followed by whole-genome sequencing of selected human and animal strains. The phylogeny was assessed by applying core-genome multilocus sequence typing (MLST) and single-nucleotide polymorphism (SNP) analyses, followed by screening for resistance genes and virulence factors. The prevalence of MRSA in Swiss pigs showed a dramatic increase from 2% in 2009 to 44% in 2017. Isolates typically belonged to clonal complex 398 (CC398), split between spa t011 and t034. The higher prevalence was mainly due to an increase in t011. spa t034 strains from farmers were found to be closely associated with porcine t034 strains. The same could be shown for spa t011 strains from horses and veterinarians. spa t034 strains had a high number of additional resistance genes, and two strains had acquired the immune evasion cluster. However, all but one of the pig spa t011 strains clustered in a separate group. Thus, the increase in pig spa t011 strains does not directly translate to humans.IMPORTANCE MRSA is an important human pathogen; thus, its increasing prevalence in livestock over the last decade has a potentially large impact on public health. Farmers and veterinarians are especially at risk due to their close contact with animals. Our work demonstrates a dramatic increase in MRSA prevalence in Swiss pigs, from 2% in 2009 to 44% in 2017. Whole-genome sequencing allowed us to show a close association between farmer and pig strains as well as veterinarian and horse strains, indicating that the respective animals are a likely source of human colonization. Furthermore, we could demonstrate that pig spa t011 strains cluster separately and are probably less likely to colonize humans than are pig spa t034 strains. This research may provide a basis for a more substantiated risk assessment and preventive measures.
