OBJECTIVE
To describe the immediate impact of the COVID-19 pandemic on cervical screening, colposcopy and treatment volumes in Ontario, Canada.
DESIGN
Population-based retrospective observational study.
SETTING
Ontario, Canada.
POPULATION
People with a cervix age of 21-69 years who completed at least one cervical screening cytology test, colposcopy or treatment procedure for cervical dysplasia between January 2019 and August 2020.
METHODS
Administrative databases were used to compare cervical screening cytology, colposcopy and treatment procedure volumes before (historical comparator) and during the first 6 months of the COVID-19 pandemic (March-August 2020).
MAIN OUTCOME MEASURES
Changes in cervical screening cytology, colposcopy and treatment volumes; individuals with high-grade cytology awaiting colposcopy.
RESULTS
During the first 6 months of the COVID-19 pandemic, the monthly average number of cervical screening cytology tests, colposcopies and treatments decreased by 63.8% (range: -92.3 to -41.0%), 39.7% (range: -75.1 to -14.3%) and 31.1% (range: -43.5 to -23.6%), respectively, when compared with the corresponding months in 2019. Between March and August 2020, on average 292 (-51.0%) fewer high-grade cytological abnormalities were detected through screening each month. As of August 2020, 1159 (29.2%) individuals with high-grade screening cytology were awaiting follow-up colposcopy.
CONCLUSIONS
The COVID-19 pandemic has had a substantial impact on key cervical screening and follow-up services in Ontario. As the pandemic continues, ongoing monitoring of service utilisation to inform system response and recovery is required. Future efforts to understand the impact of COVID-19-related disruptions on cervical cancer outcomes will be needed.
TWEETABLE ABSTRACT
COVID-19 has had a substantial impact on cervical screening and follow-up services in Ontario, Canada.
目的
描述 COVID-19 大流行对加拿大安大略省宫颈筛查、阴道镜检查和治疗量的直接影响。
设计
基于人群的回顾性观察研究。
设置
加拿大安大略省。
人群
21-69 岁有子宫颈的人群，他们在 2019 年 1 月至 2020 年 8 月期间至少完成了一次宫颈筛查细胞学检查、阴道镜检查或治疗宫颈发育不良的程序。
方法
使用行政数据库比较 COVID-19 大流行前（历史对照）和前 6 个月（2020 年 3 月至 8 月）的宫颈筛查细胞学、阴道镜检查和治疗程序量。
主要观察指标
宫颈筛查细胞学、阴道镜检查和治疗量的变化；等待阴道镜检查的高级别细胞学异常患者。
结果
在 COVID-19 大流行的前 6 个月，与 2019 年同期相比，每月平均宫颈筛查细胞学检查、阴道镜检查和治疗量分别下降了 63.8%（范围：-92.3%至-41.0%）、39.7%（范围：-75.1%至-14.3%）和 31.1%（范围：-43.5%至-23.6%）。2020 年 3 月至 8 月期间，每月平均筛查出的高级别细胞学异常减少了 292 例（51.0%）。截至 2020 年 8 月，有 1159 例（29.2%）高级别细胞学筛查异常的患者等待后续阴道镜检查。
结论
COVID-19 大流行对安大略省的主要宫颈筛查和随访服务产生了重大影响。随着大流行的继续，需要对服务利用情况进行持续监测，以提供系统响应和恢复。未来还需要努力了解 COVID-19 相关中断对宫颈癌结局的影响。
推特摘要
COVID-19 对加拿大安大略省的宫颈筛查和随访服务产生了重大影响。
