[Analysis on personal protection in occupational population at high risk for brucellosis and influencing factor in China]

Objective: To understand the current status of personal protection in occupational population at high risk for brucellosis in China and provide evidence for the evaluation of implementation of National Brucellosis Prevention and Control Plan (2016-2020). Methods: Four counties in Shanxi Province and Xinjiang Uygur Autonomous Region were selected to conduct a questionnaire survey in occupational population at high risk for brucellosis from December 2019 to July 2020 by using cross-sectional survey methods. Results: A total of 2 384 persons at high risk for brucellosis were surveyed, and the standardized utilization rate of personal protective equipment (PPE) was 20.13% (480/2 384). The utilization rate of glove, mask, rubber shoe, and work cloth were 38.26% (912/2 384), 31.80% (758/2 384), 32.01% (763/2 384) and 30.87% (736/2 384),respectively. There were significant differences in the utilization rate and standardized utilization rate of the four types of PPE among populations in different age, occupation, educational level and area groups (all P<0.001). The utilization rate and standardized utilization rate of PPE were lower in people over 60 years old, women, farmers, and those with lower educational level. The results of multivariate analysis showed that occupation and area were the influencing factors for the standardized utilization of PPE, the standardized utilization rates of PPE were higher in herdsmen and veterinarians. The standardized utilization rate of PPE in Yanggao County and Huocheng County was significantly higher than that in Zuoyun County and Hunyuan County. Conclusions: The utilization rate of the four types of PPE in occupational population at high risk for brucellosis was not high in China, and the standardized utilization rate was low, lower than the requirement in National Brucellosis Prevention and Control Plan, and there were significant differences among different areas. It is urgent to distribute PPE to occupational population at high risk for brucellosis and carry out health education about PPE utilization. Meanwhile, it is necessary to strengthen information exchange or sharing among different areas.

A-20 Factors Associated with Additional Clinic Visits in the Treatment of Sports-Related Concussion

Purpose: To determine the variables associated with additional concussion clinic visits before discharge to athletic trainer (AT). Methods: This retrospective cohort study was performed at a multi-disciplinary sports concussion center. Patients were eligible if they were ages 12–23, sustained a SRC and were seen by a clinic provider between 11/01/2017 and 10/01/2020 for concussion (n = 1504), presented to clinic within 3 months of sustaining a concussion, and had negative acute head imaging. Of 524 patients, 236 were discharged to AT after the initial clinic visit, while 288 patients required additional clinic visits. The following independent variables were assessed: age, sex, initial visit symptom score, history of prior concussions, psychiatric disorders, migraines, ADHD, and learning disorders, head imaging following concussion, family history of psychiatric disorders and migraines, and ED/Urgent Care visit. The primary disposition was patients being discharged to an AT following the initial clinic visit vs. having additional clinic visits prior to discharge to an AT. Results: The additional visit group had higher initial visit symptom scores (p = 0.002), head imaging performed more frequently (p &lt; 0.02), a family history of psychiatric disorders and/or migraines (p &lt; 0.001), more often reported a prior concussion (p = 0.02), and was younger (p = 0.014) compared to athletes with only one clinic visit. In a multiple variable model, family history of psychiatric disorders (OR = 3.12 [95%CI 1.53–6.34], p = 0.002), prior concussions (OR = 1.39 [95%CI 1.02–1.89], p = 0.037), greater initial symptom score (OR = 1.05 [95%CI 1.03–1.06], p &lt; 0.001), and younger age (OR = 0.87 [95%CI 0.77–0.98], p = 0.021) were strongly associated with additional visits. Conclusions: Among athletes treated at a regional sports concussion center, we determined that family history of psychiatric disorders, increased symptom score at initial visit, prior concussions, and younger age were each uniquely associated with needing additional clinic visits. Understanding these variables may guide treatment protocols to optimize efficiency.
