Abstract
OBJECTIVES
We investigated the impact of the COVID-19 pandemic on cancer care in a tertiary hospital in Korea without specific lockdown measures.
METHODS
A retrospective cohort of cancer patients from one of the largest tertiary hospitals in Korea was used to compare healthcare utilization in different settings (outpatient cancer clinic, the emergency department [ED], and admissions to the hematology/oncology ward) between January 1 and December 31, 2020 and the same time period in 2019. The percent changes in healthcare utilization between the 2 periods were calculated.
RESULTS
A total of 448,833 cases from the outpatient cohort, 26,781 cases from the ED cohort, and 14,513 cases from the admission cohort were reviewed for 2019 and 2020. The total number of ED visit cases significantly decreased from 2019 to 2020 by 18.04%, whereas the proportion of cancer patients remained stable. The reduction in ED visits was more prominent in patients with symptoms suspicious for COVID-19, high-acuity cases, and those who lived in non-capital city areas. There were no significant changes in the number of total visits, new cases in the outpatient clinic, or the total number of hospitalizations between the 2 periods.
CONCLUSIONS
During the pandemic, the number of ED visits significantly decreased, while the use of the outpatient clinic and hospitalizations were not affected. Cancer patients’ ED visits decreased after the COVID-19 outbreak, suggesting the potential for collateral damage outside the hospital if patients cannot reach the ED in a timely manner.
Summary
Korean summary
코로나19 이전인 2019년에 비해 코로나19 유행 첫 해인 2020년에 암환자의 1개 상급종합병원 응급실 방문이 유의하게 감소하였고, 특히 코로나19 의심 증상이 있거나, 중증도가 높거나, 비수도권 지역에 거주하는 환자에서 응급실 방문의 감소가 뚜렷하였다. 코로나19 이전과 코로나19 유행 시 외래 방문 암환자의 수, 신환 수는 큰 차이가 없었고, 입원한 암환자의 수 역시 유의한 차이가 없었다. 코로나19 대유행 시 암환자의 응급실 방문 감소는 병원 밖에서 적시에 응급실에 방문하지 못하는 부수적 피해의 가능성을 시사하여, 이에 대한 관심이 필요하다.
Key Message
The study identified a significant decrease in the emergency department visits of the cancer patients at a tertiary hospital in Korea during the COVID-19 pandemic. There were no significant changes in the number of total visits, new cases in the outpatient clinic, or the total number of hospitalizations between pre-COVID-19 and during-COVID-19 periods.

Abstract
OBJECTIVES
The coronavirus disease 2019 (COVID-19) pandemic has affected the utilization of healthcare services, including participation in cancer screening programs. We compared cancer screening participation rates for colorectal, gastric, breast, and cervical cancers among participants in the National Cancer Screening Program (NCSP) in 2019 and 2020 to address the potential distraction effect of COVID-19 on cancer screening.
METHODS
Data from the NCSP for 4 cancer types (stomach, colorectal, breast, and cervical) in 2019 and 2020 were used to calculate cancer screening participation rates by calendar month, gender, age group, and geographical region. Monthly participation rates were analyzed per 1,000 eligible individuals.
RESULTS
The screening participation rate decreased in 2020 compared to 2019 for all 4 cancers: colorectal (40.5 vs. 35.3%), gastric (61.9 vs. 54.6%), breast (63.8 vs. 55.8%), and cervical (57.8 vs. 52.2%) cancers. Following 2 major COVID-19 waves in March and December 2020, the participation rates in the 4 types of cancer screening dropped compared with those in 2019. The highest decline was observed in the elderly population aged 80 years and older (percentage change: -21% for colorectal cancer; -20% for gastric cancer; -26% for breast cancer; -20% for cervical cancer).
CONCLUSIONS
After the 2 major COVID-19 waves, the screening participation rate for 4 types of cancer declined compared with 2019. Further studies are needed to identify the indirect effects of the COVID-19 pandemic on cancer patients, such as delayed diagnoses of cancer or excess cancer deaths.
Summary
Korean summary
본 연구는 코로나 대유행 기간 전과 후 대장암, 위암, 유방암, 자궁경부암 검진 수검률 차이를 비교하고자 하였다. 첫 코로나 확진자가 발생한 2020년을 코로나 대유행 기간, 전년도 기간인 2019년을 코로나 대유행 전 기간으로 설정하며 국민건강보험공단에서 집계된 전수자료를 이용하여 암 검진 대상자 수와 수검자 수를 비교 분석하였다. 4개 암종 모두에서 2019년도와 비교하여 2020년도에 전국적으로 수검률이 감소하는 경향이 있었으며, 1차 대유행이 있었던 3월과 3차 대유행 시기인 12월에 2019년도 동기간과 비교하여 수검률이 크게 감소하였고, 80대 이상 노인 인구에서 감소폭이 다른 연령대와 비교하여 크게 나타났다.
Key Message
We found decline of the colorectal, gastric, breast and cervical cancer screening participation rates in 2020 following the two major COVID-19 waves, compared with those of 2019, and the highest decline was observed in the elderly population aged 80 years and older.
