When inquiries to the Cardiff Centre of the National Poisons Information Service were compared with hospital admissions in the eight health authorities in Wales the findings suggested fewer admissions in the area within which the centre is situated and showed a more extensive use in that area than elsewhere. High inquiry rates were associated with high hospital admission rates when the eight areas were compared. If the service were delegated to area level a more complete community use would result.
将国家毒物信息服务中心加的夫分中心接到的咨询与威尔士八个卫生部门的医院入院情况进行比较时，研究结果表明，该中心所在地区的入院人数较少，且该地区的使用情况比其他地区更为广泛。在比较这八个地区时，高咨询率与高医院入院率相关。如果将该服务下放到地区层面，将会带来更全面的社区使用。
