This survey is designed to elicit information from veterinarians and veterinary parasitologists to answer the following questions:
What experience do individuals report regarding antiparasitic drug use and antiparasitic drug resistance?
Is there current awareness of antiparasitic drug resistance in target animals?
What target animal/drug/route of administration/parasite resistance relationships do individuals report?
Which information sources do individuals use when determining which antiparasitic drugs to use or recommend?
Do individuals recommend concurrent multiple antiparasitic drugs and/or rotation of antiparasitic drugs in individual or groups of animals
Which strategies for detecting, monitoring, and/or managing antiparasitic resistance do respondents commonly use?
Which methods do individuals use to detect parasites, determine if treatment is effective, or manage resistance?
2.2. Is the choice of parasite control practices related to awareness or experience of antiparasitic drug resistance?
Which types of information would best assist end users in the safe and effective use of antiparasitic drugs?
What additional types of information could FDA use that would best assist end users in the safe and effective use of antiparasitic drugs?
Is there evidence that there is awareness of FDA’s current methods of disseminating information about indications and use of approved drugs (i.e., FOI Summaries)?
The individual survey questions are listed on the following pages. For Questions 10 to 38, the questions are followed by the objective that each question addresses and the planned analysis for results.
Survey consent confirms that survey is voluntary, respondent is over 18, and that respondent has not previously completed the survey.

Q. For the purposes of this survey, antiparasitic drug resistance is defined as the decreased effectiveness of an antiparasitic drug for parasite species and stages for which it was previously effective. This may include a moderate decline in how well the drug works initially, a shorter duration of efficacy requiring more frequent treatments, or a complete failure of the therapeutic regimen.
For each of the following species/ classes of animals, please indicate if you are aware of high, moderate, or low/ no prevalence of antiparasitic drug resistance in the United States. If you do not have sufficient experience with a species or do not know whether or not there is resistance in a species, please choose "unable to evaluate".
Species/ classes of animals: Adult horses (3 years old and older); Young horses (less than 3 years old); Dairy cattle; Cow-calf; Background/stockers; Feedlot cattle; Sheep; Goats
A. Aware of high prevalence; Aware of moderate prevalence; Aware of low/ no prevalence; Unable to evaluate
OBJECTIVE: 1.1
ANALYSIS: Fisher exact by credential type stratified by target animal. If the number of observations and distribution of data warrants, simple logistic regression will be performed to determine if credential type or animal class is associated with awareness of resistance.

Q. [For those who chose “Mixed animal/ multiple animal species” or “Other”] For the next portion of this survey, it will be helpful for FDA to know whether you are basing your answers on experience with horses, cattle, or small ruminants. Please choose the species/ target animal class that represents the animal you have the greatest experience or concern?
A. Horses; Cattle; Small ruminants
[Individuals will then be directed to target animal section chosen]
Q. Are you involved in making any recommendations or treatment decisions regarding parasite treatment or control in [cattle, horses, small ruminants]?
A. Yes; No [Respondents who choose “No” will be directed to parasite detection questions and not reported in analysis for this section.]
Q. What proportion of your clients involves you in decisions about parasite treatment and control?
A. Less than 25%; 25% to less than 50%; 50% to less than 75%; 75% or more; This question does not apply to me

Q. There are many ways to determine which antiparasitic drug to use or recommend to treat an animal or group of animals. For [cattle, horses, small ruminants], which of the following ways do you use most often? Please select up to three.
A1. Information from veterinary continuing education conferences
A2. Marketing and promotional materials for antiparasitic drugs
A3. Product label indications to determine if the drug is expected to work for the parasites I am attempting to treat
A4. Experience of other veterinarians in my practice or institution
A5. Use what I previously used for the animal(s) unless the animal owner gives information to suggest that the drug is not working anymore.
A6. Peer-reviewed scientific journal articles
A7. Test the drug in the animal population and determine if it is effective based on an evaluation of fecal egg counts
OBJECTIVE: 1.3
ANALYSIS: Frequency of responses chosen for each answer choice will be reported for all respondents and subsets of employment type and US region. Descriptive statistics will be employed to summarize the data.

Q. In your professional experience, which of the following do you use or recommend most often to determine if an antiparasitic drug is effective in [cattle, horses, small ruminants]? Please select up to three.
A1. If there is no evidence of parasitism after treatment, conclude that the drug was effective
A2. Rely on the opinion of the farmer/producer/animal owner regarding the effectiveness of the antiparasitic drug
A3. Conduct a fecal analysis after treatment (without fecal egg count)
A4. Evaluate fecal egg counts pre- OR post-treatment
A5. Evaluate fecal egg counts pre- AND post-treatment (e.g., Fecal Egg Count Reduction Test (FECRT))
A6. [Cattle, Horses] Make the determination based on resolution of clinical signs of parasitism (eg., ill-thrift, diarrhea, etc), if present at the time of treatment
A6. [Small Ruminants] Make the determination based on resolution of clinical signs of parasitism (eg., FAMACHA system for H. contortus, ill-thrift, diarrhea, etc), if present at the time of treatment
A7. [Cattle, Small Ruminants] Use production data (milk production, weight gains, reproductive parameters) to determine if the drug is effective
OBJECTIVE: 2.1
ANALYSIS: Frequency of responses chosen for each choice by credential type and target animal class will be reported. Descriptive statistics will be employed to summarize the data.

Q. Which one of the following statements best represents the method you use or recommend to determine fecal egg count reduction in [cattle, horses, small ruminants]?
A1. FECRT based on a comparison of pre- and post- treatment fecal egg counts of a treated group/ animal
A2. FECRT based on a comparison of post-treatment fecal egg counts of a treated and an untreated-control group/ animal
A3. FECRT includes pre- and post-treatment fecal egg counts from both an untreated- control and treated group/ animal
A4. Other (please specify)
OBJECTIVE: 2.1
ANALYSIS: Descriptive analysis or measurement of association as warranted between use and credential type, awareness and experience of antiparasitic drug resistance, adjusted by region if necessary.

Q. Have you changed the management practices you implement or recommend for parasite control in [cattle, horses, small ruminants] in response to antiparasitic drug resistance? Please choose one answer.
A1. No, because I have not experienced any resistance
A2. No, because changes have not been necessary
A3. Yes, in response to information about resistance
A4. Yes, in response to resistance that I have experienced
A5. Other (please specify)
OBJECTIVE: 2.2
ANALYSIS: Descriptive analysis of responses. Also examines internal validity of survey. Individuals who report that they have not been aware of or experienced antiparasitic drug resistance should not have changed management practices due to experience with antiparasitic drug resistance. The information gained from this question will also inform interpretation of responses to question 31 above.

Q. Freedom of Information (FOI) Summaries are available electronically through http://www.fda.gov/AnimalVeterinary/Products/default.htm which summarize the safety and effectiveness information submitted to support the approval of animal drugs. Were you aware of the availability of FOI Summaries? If yes, which parts of the FOI Summary do you find most useful?
A. Yes; No
OBJECTIVE: 3.1
ANALYSIS: Outcome of interest is respondents’ awareness and use of Freedom of Information Summaries especially by awareness, credential, and report and awareness of antiparasitic drug resistance. Responses will not be generalized to all veterinarians or veterinary parasitologists, but may suggest that further educational outreach or research is needed.
