Risk factors for suicide, attitudes toward mental illness, and practice-related stressors among US veterinarians.

OBJECTIVE: To evaluate the prevalence of suicide risk factors, attitudes toward mental illness, and practice-related stressors among US veterinarians. DESIGN: Cross-sectional survey. SAMPLE: 11,627 US veterinarians. PROCEDURES: Between July 1 and October 20, 2014, a Web-based questionnaire was made available through the Veterinary Information Network (VIN), VIN News Service, JAVMA News, and email messages to US veterinarians sent by a veterinary medical association, agriculture or livestock department, or health department of each state (except Maine) and Puerto Rico. RESULTS: Of 11,627 respondents, 3,628 (31%) were male. Modal age category was 30 to 39 years, and modal range for years practicing veterinary medicine was 10 to 19 years. There were 7,460 (64%) respondents who primarily practiced small animal medicine, and 4,224 (36%) who were practice owners. There were 1,077 (9%) respondents with current serious psychological distress. Since leaving veterinary school, 3,655 (31%) respondents experienced depressive episodes, 1,952 (17%) experienced suicidal ideation, and 157 (1%) attempted suicide. Currently, 2,228 (19%) respondents were receiving treatment for a mental health condition. Only 3,250 of 10,220 (32%) respondents somewhat or strongly agreed that people are sympathetic toward persons with mental illness. The most commonly reported practice-related stressor was demands of practice. CONCLUSIONS AND CLINICAL RELEVANCE: In this survey, approximately 1 in 11 veterinarians had serious psychological distress and 1 in 6 experienced suicidal ideation since leaving veterinary school. Implementing measures to help veterinarians cope with practice-related stressors and reducing barriers veterinarians face in seeking mental health treatment might reduce the risk for suicide among veterinarians.

Notes from the field: prevalence of risk factors for suicide among veterinarians - United States, 2014.

Veterinarians are believed to be at increased risk for suicide compared with the general population. Few data on the occurrence of suicidal behavior and suicide risk factors among U.S. veterinarians are available. Veterinarians participating in two wellness summits held during September 2013 concluded that more research is needed on veterinarians and their mental health.

Association of short-term exposure to ground-level ozone and respiratory outpatient clinic visits in a rural location - Sublette County, Wyoming, 2008-2011.

OBJECTIVE: Short-term exposure to ground-level ozone has been linked to adverse respiratory and other health effects; previous studies typically have focused on summer ground-level ozone in urban areas. During 2008-2011, Sublette County, Wyoming (population: ~10,000 persons), experienced periods of elevated ground-level ozone concentrations during the winter. This study sought to evaluate the association of daily ground-level ozone concentrations and health clinic visits for respiratory disease in this rural county. METHODS: Clinic visits for respiratory disease were ascertained from electronic billing records of the two clinics in Sublette County for January 1, 2008-December 31, 2011. A time-stratified case-crossover design, adjusted for temperature and humidity, was used to investigate associations between ground-level ozone concentrations measured at one station and clinic visits for a respiratory health concern by using an unconstrained distributed lag of 0-3 days and single-day lags of 0 day, 1 day, 2 days, and 3 days. RESULTS: The data set included 12,742 case-days and 43,285 selected control-days. The mean ground-level ozone observed was 47 ± 8 ppb. The unconstrained distributed lag of 0-3 days was consistent with a null association (adjusted odds ratio [aOR]: 1.001; 95% confidence interval [CI]: 0.990-1.012); results for lags 0, 2, and 3 days were consistent with the null. However, the results for lag 1 were indicative of a positive association; for every 10-ppb increase in the 8-h maximum average ground-level ozone, a 3.0% increase in respiratory clinic visits the following day was observed (aOR: 1.031; 95% CI: 0.994-1.069). Season modified the adverse respiratory effects: ground-level ozone was significantly associated with respiratory clinic visits during the winter months. The patterns of results from all sensitivity analyzes were consistent with the a priori model. CONCLUSIONS: The results demonstrate an association of increasing ground-level ozone with an increase in clinic visits for adverse respiratory-related effects in the following day (lag day 1) in Sublette County; the magnitude was strongest during the winter months; this association during the winter months in a rural location warrants further investigation.

Assessment of vaccine exemptions among Wyoming school children, 2009 and 2011.

During 2010-2011, varicella vaccination was an added requirement for school entrance in Wyoming. Vaccination exemption rates were compared during the 2009-2010 and 2011-2012 school years, and impacts of implementing a new childhood vaccine requirement were evaluated. All public schools, grades K-12, were required to report vaccination status of enrolled children for the 2009-2010 and 2011-2012 school years to the Wyoming Department of Health. Exemption data were analyzed by exemption category, vaccine, county, grade, and rurality. The proportion of children exempt for ≥ 1 vaccine increased from 1.2% (1,035/87,398) during the 2009-2010 school year to 1.9% (1,678/89,476) during 2011-2012. In 2011, exemptions were lowest (1.5%) in urban areas and highest (2.6%) in the most rural areas, and varicella vaccine exemptions represented 67.1% (294/438) of single vaccination exemptions. Implementation of a new vaccination requirement for school admission led to an increased exemption rate across Wyoming.
