This study determined the proportion of homes with functioning smoke alarms in a low-income area experiencing a high rate of residential fire-related injuries.
An on-site survey of households was conducted to confirm the results of a telephone survey.
In the telephone survey, 71% of households reported having functioning smoke alarms. In the household survey, 66% of households reported having functioning alarms; however, when the alarms were tested, the percentage dropped to 49%.
Telephone surveys may overestimate the presence of functioning smoke alarms in some populations. Thus, the use of telephone surveys to establish baseline measures could significantly affect the evaluation of smoke-alarm giveaway programs.
本研究确定了在一个住宅火灾相关伤害发生率较高的低收入地区,装有可正常使用烟雾报警器的家庭比例。
对家庭进行了现场调查,以确认电话调查的结果。
在电话调查中,71%的家庭报告称有可正常使用的烟雾报警器。在入户调查中,66%的家庭报告称有可正常使用的报警器;然而,当对报警器进行测试时,这一比例降至49%。
电话调查可能会高估某些人群中可正常使用烟雾报警器的情况。因此,使用电话调查来确定基线指标可能会显著影响对烟雾报警器赠送项目的评估。
