Abstract

Syndromic surveillance is a type of public health surveillance that utilizes nonspecific indicators or symptoms associated with a particular disease or condition to detect and track disease outbreaks early. However, data completeness has been a significant challenge for syndromic surveillance systems in many countries. Incomplete data may make it difficult to accurately identify anomalies or trends in surveillance data. In this study, a new disease mapping method based on a high‐accuracy, low‐rank tensor completion (HaLRTC) algorithm is proposed to estimate the quarterly positivity rate of the human influenza virus (IFV) based on highly insufficient 2010–2015 respiratory syndromic surveillance data from the subtropical monsoon region of China. The HaLRTC algorithm is a spatiotemporal interpolation method applied to fill in missing or incomplete data using a low‐rank tensor structure. The results show that the accuracy (R2 = 0.880, RMSE = 0.037) of the proposed method is much higher than that of three traditional disease mapping methods: Cokriging, hierarchical Bayesian, and sandwich estimation methods. This study provides a new disease mapping approach to improve the quality and completeness of data in syndrome surveillance or other familiar systems with a large proportion of missing data.

一种新的疾病绘图方法,用于提高缺失率较高的综合征监测数据的完整性
综合征监测是一种公共卫生监测,它利用与特定疾病或状况相关的非特异性指标或症状来及早发现和跟踪疾病的爆发。然而,数据完整性一直是许多国家综合征监测系统面临的重大挑战。不完整的数据可能导致难以准确识别监测数据中的异常情况或趋势。本研究提出了一种基于高精度、低秩张量补全(HaLRTC)算法的新型疾病映射方法,以估算基于中国亚热带季风区 2010-2015 年高度不充分的呼吸道症候群监测数据的人流感病毒(IFV)季度阳性率。HaLRTC 算法是一种时空插值方法,利用低秩张量结构填补缺失或不完整的数据。结果表明,所提方法的准确度(R2 = 0.880,RMSE = 0.037)远高于三种传统疾病绘图方法:Cokriging 法、层次贝叶斯法和三明治估计法。这项研究提供了一种新的疾病绘图方法,可用于提高综合征监测或其他熟悉的系统中数据的质量和完整性,因为这些系统中数据缺失的比例很大。
