Cancer datasets drive report quality, but require more work to inform compliant reports. The aim of this study was to correlate the number of words with measures of quality, to examine the impact of the drive for improved quality on the workload of histopathology reporting over time.
We examined the first 10 reports of colon, breast, renal, lung and ovarian carcinoma, melanoma resection, nodal lymphoma appendicitis and seborrhoeic keratosis (SK) issued in 1991, 2001 and 2011. Correlations were analysed using Pearson's partial correlation coefficients. Word count increased significantly over time for most specimen types examined. Word count almost always correlated with units of information, indicating that the word count was a good measure of the amount of information contained within the reports; this correlation was preserved following correction for the effect of time. A good correlation with compliance with cancer datasets was also observed, but was weakened or lost following correction for the increase in word count and units of information that occurred between time points.
These data indicate that word count could potentially be used as a measure of information content if its integrity and usefulness are continuously validated. Further prospective studies are required to assess and validate this approach.
癌症数据集推动报告质量，但需要更多工作来告知符合规定的报告。本研究的目的是分析词汇量与质量指标的相关性，以考察随着时间的推移，提高质量的驱动力对组织病理学报告工作量的影响。
我们分析了 1991 年、2001 年和 2011 年首次发布的 10 份结肠癌、乳腺癌、肾癌、肺癌和卵巢癌、黑色素瘤切除、淋巴结淋巴瘤阑尾炎和脂溢性角化病（SK）报告。使用 Pearson 部分相关系数分析相关性。对于大多数检查的标本类型，词汇量随时间显著增加。词汇量几乎总是与信息量单位相关，表明词汇量是报告中包含信息量的良好指标；在纠正时间效应后，这种相关性仍然存在。与癌症数据集的一致性也有很好的相关性，但在纠正词汇量和信息量在时间点之间增加的影响后，相关性减弱或丢失。
这些数据表明，如果词汇量的完整性和有用性得到持续验证，词汇量可以作为信息量的衡量指标。需要进一步的前瞻性研究来评估和验证这种方法。
