In England, routine invitations for cervical screening were reduced between April 2020 and June 2020 due to the COVID-19 pandemic. We quantify the impact of COVID-19 disruptions on attendance and excess diagnoses of cervical cancer (CC).
Using Public Health England CC screening data on laboratory samples received in 2018 as a baseline we quantify the reduction in screening attendances due to the COVID-19 pandemic between April 2020 and March 2021 for women aged 25-64. We model the impact on excess CC diagnoses assuming once invitations resume 87.5% of women attend within 12 months and 12.5% delay screening for 3 or 5 years (depending on age).
The number of samples received at laboratories was 91% lower than expected during April, 85% during May and 43% during June 2020 compared to the same period in 2018. Although on average laboratories received 12.6% more samples between August 2020 and April 2021 than over the same months in 2018, by April 2021 there was a short fall of 200,949 samples (6.4% fewer than in 2018). An excess of 41 CC (4.0 per 100,000 women with a maximum screening delay of 12 months) are predicted to occur among the estimated 1,024,794 women attending this screening round with a delay. An excess of 60 CC (41.0 per 100,000 women) are predicted to occur among the estimated 146,391 women who do not attend this screening round.
Prompt restoration of cervical screening services limited the impact on excess CC diagnoses. However, in 2020 a 6.4% shortfall of screening samples was observed. Every effort should be made to reassure these women that services are open and safe to attend.
在 2020 年 4 月至 6 月期间,由于 COVID-19 大流行,英格兰常规的宫颈癌筛查邀请减少。我们量化了 COVID-19 干扰对宫颈癌(CC)就诊人数和额外诊断的影响。
我们使用 2018 年英格兰公共卫生署 CC 筛查实验室样本数据作为基线,量化了 2020 年 4 月至 2021 年 3 月期间,25-64 岁女性因 COVID-19 大流行导致的筛查人数减少情况。我们假设一旦恢复邀请,87.5%的女性将在 12 个月内参加筛查,12.5%的女性将延迟 3 年或 5 年(取决于年龄),以此来建模对额外 CC 诊断的影响。
与 2018 年同期相比,2020 年 4 月、5 月和 6 月实验室收到的样本数量分别减少了 91%、85%和 43%。尽管 2020 年 8 月至 2021 年 4 月期间,实验室平均收到的样本比 2018 年同期多 12.6%,但到 2021 年 4 月,样本数量减少了 200949 个(比 2018 年减少 6.4%)。预计在估计参加此次筛查的 1024794 名女性中,由于延迟,会出现 41 例额外的 CC(每 10 万名女性中有 4.0 例)。预计在估计不参加此次筛查的 146391 名女性中,会出现 60 例额外的 CC(每 10 万名女性中有 41.0 例)。
及时恢复宫颈癌筛查服务,限制了额外 CC 诊断的发生。然而,在 2020 年,筛查样本出现了 6.4%的短缺。应尽一切努力向这些女性保证,服务是开放的,并且安全可参加的。
