Officially, the national official sentinel surveillance of infectious diseases (NOSSID) has been used to estimate the number of influenza patients nationwide; NOSSID is based on the Law Concerning the Prevention of Infectious Diseases and Medical Care for Patients of Infections (the Infectious Diseases Control Law). Prescription Surveillance (PS) has also provided a numerical estimate of influenza patients. This study compared these 2 estimations using NOSSID and PS with the numbers of influenza patients from all electronic medical claims (NDBEMC), which had the nearly-comprehensive data from surveys. Results showed that the estimate from NOSSID was about twice the estimate from the NDBEMC. However, the estimated number from the PS was almost equivalent to that from the NDBEMC. The estimated number of patients from NOSSID might not be precise, but NOSSID itself may be useful to monitor influenza trends.
官方上，国家传染病官方哨点监测（NOSSID）已被用于估算全国流感患者数量；NOSSID是基于《传染病预防及感染患者医疗法》（《传染病控制法》）开展的。处方监测（PS）也提供了流感患者数量的数值估算。本研究将使用NOSSID和PS得出的这两种估算结果与来自所有电子医疗理赔（NDBEMC）的流感患者数量进行了比较，NDBEMC拥有来自调查的几乎全面的数据。结果显示，NOSSID的估算值约为NDBEMC估算值的两倍。然而，PS的估算数量几乎与NDBEMC的估算数量相当。来自NOSSID的患者估算数量可能不准确，但NOSSID本身可能有助于监测流感趋势。
