[Analysis of the time for observation and related factors at clinics after vaccination among children's parents].

ABSTRACT

Objective: To understand the time for observation and related factors in the clinics after vaccination among children's parents. Methods: From December 2019 to January 2020, parents of children aged 0-3 years were recruited by multiple-stage sampling from 34 vaccination clinics in 12 districts and counties in 6 provinces (Shandong, Guangdong, Henan, Sichuan, Inner Mongolia, and Liaoning). A questionnaire survey on the time of observation after vaccination was conducted. A multivariate logistic regression model was used to analyze the related factors of parental observation time after vaccination. Results: A total of 3 292 parents of 0-3 year's old children were selected, and 3 178 parents were finally included in the analysis. 87.85%(2 792/3 178) of the parents reported that the observation time after vaccination at clinics was ≥30 minutes. Multivariate logistic regression analysis showed that, after adjusting for the regions, the main factors affecting the observation time at clinics after vaccination among parents appeared as observation time informed by physicians at the clinic appeared ≥30 minutes (OR=31.622, 95%CI 19.847-50.384), parents were medical personnel (OR=2.779, 95%CI 1.505-5.133), parents being volunteers working on vaccination-related publicity and education activities (OR=1.986, 95%CI 1.438-2.743), parents aged 35 years old or above (OR=1.900, 95%CI 1.215-2.971), being parents of the first child (OR=1.663, 95%CI 1.282-2.156), per capita annual income of the family as 8 000- Yuan (OR=1.646, 95%CI 1.168-2.319), children aged 0-12 months old (OR=1.646, 95%CI 1.203-2.252) or 13-24 months old (OR=1.506, 95%CI 1.064-2.133), obedient to physicians' advice at the clinic (OR=1.481, 95%CI 1.067-2.055). Conclusions: The proportions of parents observed for ≥30 minutes at the clinics of vaccination were high. When the information was from the physicians at the vaccination clinic, the observation time was the most critical factor for parents to observe at clinics as required.
