We compared the accuracy of a conceptually simple pediatric weight estimation technique, the finger counting method, with other commonly used methods.
We prospectively collected cross-sectional data on a convenience sample of 207 children aged 1 to 9 presenting to our pediatric emergency department. Bland-Altman plots were constructed to compare the finger counting method to the Broselow tape method, parental estimate, the Luscombe formula, and the advanced pediatric life support (APLS) formula. Proportions within 10% and 20% of measured weight were compared.
Mean difference and range of agreement in kilograms for Bland-Altman plots were as follows: -1.8 (95% confidence interval [CI], -2.3 to -1.3) and 15.4 (95% CI, 13.6-17.2) for the finger counting method; -1.4 (95% CI, -2.0 to -0.9) and 15.8 (95% CI, 13.9-17.6) for the Broselow method; -0.02 (95% CI, -0.53 to 0.49) and 14.8 (95% CI, 13-16.6) for parental estimate; 0.2 (95% CI, -0.33 to 0.72) and 15.3 (95% CI, 13.5-17.2) for the Luscombe formula; and -3.8 (95% CI, -4.4 to -3.2) and 17.2 (95% CI, 15.2-19.2) for the APLS formula. The finger counting method estimated weights within 10% in 59% of children (95% CI, 52%-65%) and within 20% in 87% of children (95% CI, 81%-91%). Proportions within 10% were similar for all methods, except the APLS method, which was lower.
The finger counting method is an acceptable alternative to the Broselow method for weight estimation in children aged 1 to 9 years. It outperforms the traditional APLS method but underestimates weights compared with parental estimate and the Luscombe formula.
我们比较了一种概念简单的儿科体重估计技术，即手指计数法，与其他常用方法的准确性。
我们前瞻性地收集了 207 名 1 至 9 岁就诊于儿科急诊的儿童的横断面数据。我们构建了 Bland-Altman 图，以比较手指计数法与 Broselow 胶带法、父母估计值、Luscombe 公式和高级儿科生命支持 (APLS) 公式。比较了测量体重的 10%和 20%范围内的比例。
Bland-Altman 图的平均差值和一致性范围如下：手指计数法为-1.8（95%置信区间[CI]，-2.3 至-1.3）和 15.4（95%CI，13.6-17.2）；Broselow 法为-1.4（95%CI，-2.0 至-0.9）和 15.8（95%CI，13.9-17.6）；父母估计值为-0.02（95%CI，-0.53 至 0.49）和 14.8（95%CI，13-16.6）；Luscombe 公式为 0.2（95%CI，-0.33 至 0.72）和 15.3（95%CI，13.5-17.2）；APLS 公式为-3.8（95%CI，-4.4 至-3.2）和 17.2（95%CI，15.2-19.2）。手指计数法在 59%（95%CI，52%-65%）的儿童中估计体重在 10%以内，在 87%（95%CI，81%-91%）的儿童中估计体重在 20%以内。除 APLS 方法外，所有方法的 10%以内比例均相似，而 APLS 方法的比例较低。
手指计数法是 1 至 9 岁儿童体重估计的一种可接受的 Broselow 方法替代方法。它优于传统的 APLS 方法，但与父母估计值和 Luscombe 公式相比，它低估了体重。
