Cognitive level of first aid knowledge regarding small area burn among 2 723 child caregivers in Shanghai: a cross-sectional survey and analysis

Objective To assess the cognitive level of first aid knowledge regarding the small area burn among the child caregivers in Shanghai and improve the level of first aid for small area burn in children. Methods From November 2017 to March 2018, 7 municipal districts in Shanghai were selected according to the random number table, from which 2 750 students of 4 nurseries, 5 kindergartens, 6 primary schools, and 2 junior middle schools were selected by adopting the convenience sampling method. Each student was limited to one caregiver as the research object. A cross-sectional survey was conducted on the cognitive level of first aid knowledge regarding small area burn among the caregivers with self-designed questionnaire through WeChat and Tencent QQ. The age, burn experience, and scarring after burns in children, the prevalence rate of burn in children of different age groups, the educational background of caregivers and their social relationship with their children, and the measures taken by caregivers firstly after small area burn occurred among their children were recorded. The choices of applying the folk prescription drugs to the wounds of their children made by caregivers and those with different educational backgrounds were recorded. The choices of applying daily necessities to the wound of their children made by caregivers were recorded. The caregivers′ knowledge of standard first aid measures for small area burn, and the knowledge of caregivers with different educational backgrounds of all standard first aid measures for small area burn were recorded. The caregivers′ choices of hospitals for treatment the first time, and the choices of going to the Grade Ⅲ Level A hospital with burn specialty for treatment made by caregivers with different knowledge levels about first aid measures for small area burn and those by caregivers whose children did or didn′t have burn experience were recorded. The caregivers′ choices of different types of medical institutions with burn specialty or specialized in burn treatment, and choices of going to burn department of comprehensive Grade Ⅲ Level A hospital for treatment made by caregivers with different knowledge levels about first aid measures for small area burn were recorded. Data were processed with Pearson chi-square test and partitions of chi-square test. Results The effective recovery rate of questionnaire was 99.0% (2 723/2 750). The ages of children were mainly 6-11 years [64.7% (1 762/2 723)]The prevalence of burn in children was 19.4% (527/2 723). There was no statistically significant difference in the overall comparison of burn prevalence of children among the age groups (χ²=1.424, P>0.05). The percentage of scar formation after burn in children was 27.3% (144/527). The education backgrounds of caregivers were mainly undergraduate [40.2% (1 094/2 723)], and their social relationships with children were mainly children′s mothers [74.6% (2 030/2 723)]. Assuming that their children suffered from minor burns, the measures firstly taken by 74.0% (2 016/2 723) of the caregivers was to immediately access cool running water and remove clothing on the wound of children. Totally 19.2% (523/2 723) of the caregivers chose to apply folk prescription drugs for their burn children by themselves, and the percentage of caregivers with education background of junior middle school choosing to apply folk prescription drugs for their burn children by themselves was significantly higher than that of caregivers with education background of junior college, undergraduate, or graduate (χ²=18.502, 20.642, 13.319, P<0.05). Totally 49.2% (1 340/2 723) of caregivers chose to daub many kinds of daily necessities for their burn children by themselves. Totally 39.2% (1 068/2 723) of caregivers knew all standard first aid measures for small area burn, the percentage of caregivers with education background of undergraduate knowing all standard first aid measures for small area burn was significantly higher than that of caregivers with education background of senior high school and secondary specialized school (χ²=11.234, P<0.05). Assuming that their children suffered from minor burns, 39.0% (1 063/2 723) of the caregivers chose to go to the nearest hospital for treatment the first time, the percentage of caregivers who knew all standard first aid measures for small area burn choosing to go to Grade Ⅲ Level A hospital with burn specialty for treatment the first time was similar with that of caregivers who did not know/did not fully know (χ²=3.528, P>0.05), and the percentage of caregivers whose children had burn experience choosing to go to Grade Ⅲ Level A hospital with burn specialty for treatment in the first time was similar with that of caregivers whose children didn′t have burn experience (χ²=3.521, P>0.05). Among all medical institutions with burn specialty or specialized in burn treatment, 28.0% (762/2 723) of the caregivers chose to go to comprehensive Grade Ⅲ Level A hospital for treatment, and the percentage of caregivers who knew all standard first aid measures for small area burn choosing to go to comprehensive Grade Ⅲ Level A hospital for treatment was significantly higher than that of caregivers who did not know/did not fully know (χ²=4.890, P<0.05). Conclusions The caregivers of children are mainly children′s mothers with education background of undergraduate in Shanghai, and caregivers′ cognitive levels of first aid knowledge regarding the small area burn are low. Only a few caregivers know all standard first aid measures for small area burn, and there are still some caregivers who have the wrong idea of applying folk prescription drugs or daily necessities for children by themselves. The publicity and education of basic first aid knowledge of burn should be strengthened through various channels such as burn simulation exercise and network, and caregivers should be guided to take their children to hospitals with burn specialty for treatment after occurrence of burn in children, so as to obtain more professional medical treatment.
