Various methods of soliciting participation for a large smoke detector giveaway program were tested to determine the most effective method of distributing smoke detectors to a high risk urban population.
The target area was a 24 square mile (62 km2) section on the south side of Oklahoma City where 16% (73,301) of the city's population resided in 16% (34,845) of the dwellings (excluding apartments). Of the 66 persons in Oklahoma City who were injured in residential fires from September 1987 to April 1990, 45% (30) were in the target area. Of the target area injuries, 47% resulted from fires started by children playing with fire (fireplay).
The number of homes without detectors was estimated by telephone survey. Four different methods of soliciting participants were used, including notifying residents by mail; placing flyers on the doors of every habitable residence; and displaying flyers at public places (grocery stores, convenience stores, restaurants, etc). Each of these methods alerted residents that free smoke detectors were available at specific fire stations. The fourth method was distributing detectors door-to-door (canvassing).
The canvassing method resulted in significantly more smoke detectors being distributed to homes without detectors (107%) than any of the three other methods (18%) (p < 0.00001). The canvassing method distributed detectors to 31% of the total target homes, compared with 5% with the other methods (p < 0.00001). Canvassing also resulted in the lowest estimated cost per detector distributed ($1.96) (all other methods, $3.95), and in the largest number distributed per volunteer hour (5.9 v 3.1 detectors per hour by other methods).
Distributing smoke detectors directly to homes (canvassing) was the most effective and cost efficient method to reach high risk urban residents.
对大型烟雾探测器赠送项目中多种征集参与者的方法进行测试,以确定向城市高危人群分发烟雾探测器的最有效方法。
目标区域是俄克拉荷马城南部一个24平方英里(62平方公里)的区域,该市16%(73,301人)的人口居住在该区域16%(34,845套)的住宅中(不包括公寓)。在1987年9月至1990年4月期间俄克拉荷马城因住宅火灾受伤的66人中,45%(30人)在目标区域。在目标区域的受伤案例中,47%是由儿童玩火引发的火灾导致的。
通过电话调查估算没有探测器的家庭数量。使用了四种不同的征集参与者的方法,包括邮寄通知居民;在每栋可居住住宅的门上放置传单;在公共场所(杂货店、便利店、餐馆等)展示传单。这些方法都告知居民在特定消防站可获得免费烟雾探测器。第四种方法是挨家挨户分发探测器(挨户访问)。
挨户访问方法向没有探测器的家庭分发的烟雾探测器数量(107%)显著多于其他三种方法(18%)(p<0.00001)。挨户访问方法向31%的目标家庭分发了探测器,而其他方法为5%(p<0.00001)。挨户访问还使得每个分发的探测器估计成本最低(1.96美元)(其他所有方法为3.95美元),并且每志愿者小时分发的探测器数量最多(每小时5.9个,其他方法为每小时3.1个)。
直接向家庭分发烟雾探测器(挨户访问)是接触城市高危居民的最有效且最具成本效益的方法。
