AIHW - National Cancer Screening - Participation in the National Bowel Cancer Screening Program (PHN) 2014-2017

This dataset presents the footprint of participation statistics in the National Bowel Cancer Screening Program (NBCSP) for people aged 50 to 74. The NBCSP began in 2006. It aims to reduce morbidity and mortality from bowel cancer by actively recruiting and screening the eligible target population for early detection or prevention of the disease. The data spans the years of 2014-2017 and is aggregated to 2015 Department of Health Primary Health Network (PHN) areas, based on the 2011 Australian Statistical Geography Standard (ASGS).\n\nCancer is one of the leading causes of illness and death in Australia. Cancer screening programs aim to reduce the impact of selected cancers by facilitating early detection, intervention and treatment. Australia has three cancer screening programs:\n\n * BreastScreen Australia\n\n * National Cervical Screening Program (NCSP)\n\n * National Bowel Cancer Screening Program (NBCSP)\n\nThe National cancer screening programs participation data presents the latest cancer screening participation rates and trends for Australia's 3 national cancer screening programs. The data has been sourced from the Australian Institute of Health and Welfare (AIHW) analysis of National Bowel Cancer Screening Program register data, state and territory BreastScreen Australia register data and state and territory cervical screening register data.\n\nFor further information about this dataset, visit the data source:[Australian Institute of Health and Welfare - National Cancer Screening Programs Participation Data Tables](https://www.aihw.gov.au/reports/cancer-screening/national-cancer-screening-programs-participation/data).\n\nPlease note:\n\n * AURIN has spatially enabled the original data using the [Department of Health - PHN Areas.](https://www1.health.gov.au/internet/main/publishing.nsf/Content/PHN-Home)\n\n * Participation rates represent the percentage of people invited to screen through the NBCSP during the relevant 2-year period, who returned a completed screening test within that period or by 30 June of the following year. The number of individuals invited to screen excludes those who deferred or opted out without completing their screening test.\n\n * PHN areas were assigned to NBCSP invitees using an SA1 to PHN correspondence. Those invitees without reliable SA1 details were mapped with a postcode to PHN correspondence instead, which may lead to some minor inaccuracies in results.\n\n * Some invitee SA1 codes and postcodes cannot be attributed to a PHN. These invitees were included in an 'Unknown' group where applicable.\n\n * Some postcodes cross PHN boundaries, leading to slight inaccuracies.\n\n * The time period of some PHN data presented is prior to the initiation of PHNs, which were in established in June 2015.\n\n * Biennial screening for those aged 50-74 is not fully rolled out. During the time period reported, the specific ages invited within the 50-74 age range included 50, 54, 55, 58, 60, 64, 65, 68, 70, 72 and 74.\n\n * These results calculate participation rates using the new NBCSP performance indicator specifications. This indicator now measures a 2-year invitation period and also excludes those who opted off or suspended participation. Therefore, these results cannot be compared to rates reported prior to 2014.\n\n * NBCSP participation rates per area are not related to bowel cancer incidence rates.\n\n * The 2014-2015 period covers 1 January 2014 to 31 December 2015, the 2015-2016 period covers 1 January 2015 to 31 December 2016, and the 2016-2017 period covers 1 January 2016 to 31 December 2017.\n\n * The number of people in different PHNs may not sum to 'Australia' total due to rounding.\n\n * PHN205 Murray includes Albury, NSW.\n

本数据集收录了50至74岁人群参与国家肠癌筛查计划（National Bowel Cancer Screening Program, NBCSP）的统计数据。该计划于2006年启动，旨在通过主动招募符合条件的目标人群并进行筛查，实现肠癌的早诊早治或疾病预防，从而降低肠癌的发病率与死亡率。本数据集的时间跨度为2014年至2017年，数据依据2011年澳大利亚统计地理标准（Australian Statistical Geography Standard, ASGS）进行聚合，汇总至2015年澳大利亚卫生部基层卫生网络（Primary Health Network, PHN）辖区范围。

癌症是澳大利亚致病与致死的主要诱因之一。癌症筛查计划旨在通过推动早诊早治与干预措施，降低特定癌症造成的健康负担。澳大利亚目前设有三项国家级癌症筛查计划：

* 澳大利亚乳腺癌筛查计划（BreastScreen Australia）

* 国家宫颈癌筛查计划（National Cervical Screening Program, NCSP）

* 国家肠癌筛查计划（NBCSP）

本国家级癌症筛查计划参与数据涵盖了澳大利亚三项国家级癌症筛查计划的最新筛查参与率及趋势变化。数据来源于澳大利亚健康与福利研究所（Australian Institute of Health and Welfare, AIHW）对国家肠癌筛查计划登记数据、各州及领地的澳大利亚乳腺癌筛查计划登记数据，以及各州及领地的宫颈癌筛查登记数据的分析结果。

请注意：

* AURIN已借助[卫生部基层卫生网络辖区](https://www1.health.gov.au/internet/main/publishing.nsf/Content/PHN-Home)完成原始数据的空间化适配。

* 参与率指在对应两年筛查周期内，受邀参与国家肠癌筛查计划的人群中，于该周期内或次年6月30日前完成有效筛查检测的人数占比。受邀筛查人数不包括延迟筛查或未完成筛查即退出的个体。

* 国家肠癌筛查计划受邀者的基层卫生网络辖区归属通过统计区域1级（Statistical Area Level 1, SA1）与PHN的对应关系完成映射；对于无可靠SA1信息的受邀者，则通过邮政编码与PHN的对应关系进行匹配，这一处理方式可能导致结果存在细微偏差。

* 部分受邀者的SA1编码及邮政编码无法匹配至对应的PHN辖区，此类受邀者将被归入‘未知’组别（若适用）。

* 部分邮政编码覆盖多个PHN辖区，这也会导致结果存在轻微偏差。

* 本次展示的部分PHN辖区数据的时间早于PHN体系的启动时间——PHN体系于2015年6月正式设立。

* 针对50至74岁人群的两年一次肠癌筛查尚未完全普及。在本次数据覆盖的周期内，50至74岁年龄段中受邀参与筛查的具体年龄为50, 54, 55, 58, 60, 64, 65, 68, 70, 72及74岁。

* 本次结果基于新版国家肠癌筛查计划绩效指标规范计算参与率。新指标以两年为邀请周期，同时排除了主动退出或暂停参与筛查的个体，因此本结果无法与2014年之前公布的参与率数据进行对比。

* 各辖区的国家肠癌筛查计划参与率与肠癌发病率并无关联。

* 2014-2015周期指1 January 2014至31 December 2015，2015-2016周期指1 January 2015至31 December 2016，2016-2017周期指1 January 2016至31 December 2017。

* 由于四舍五入处理，各PHN辖区的人数总和可能与澳大利亚全国总人数存在小幅差异。

* PHN205 Murray包含新南威尔士州的奥尔伯里地区。
