Effects of the Coronavirus disease 2019 pandemic on mortality in patients with lung cancer: A multiple mediation analysis in Japan

COVID-19 pandemic has had a substantial effect on healthcare systems worldwide, including the care of patients with lung cancer. The impact of healthcare disruptions and behavioral changes on lung cancer mortality is unclear. Patients newly diagnosed with lung cancer during the pandemic period 2020-2021 were compared with those diagnosed in the pre-pandemic 2018-2019. The primary outcome was all-cause mortality within 1 year. Cox proportional hazards regression analyses were conducted to estimate the changes in mortality between pandemic and pre-pandemic. Multiple mediation analyses were performed to determine the factors that accounted for the changes in mortality. In total, 5785 patients with lung cancer were included in this study. The overall mortality rate was significantly higher during the pandemic compared with the pre-pandemic (crude hazard ratio [HR]: 1.19, 95% confidence interval [CI]: 1.05, 1.29). Mediation analyses showed that not receiving tumor-directed treatment, diagnosis at an older age, and decreased diagnosis through cancer screening significantly accounted for 17.5% (95%CI: 4.2, 30.7), 13.9% (95%CI: 0.8, 27.0), and 12.4% (95%CI: 3.0, 21.8) of the increased mortality, respectively. This study revealed a significant increase in mortality risk in patients with lung cancer who have not received tumor-directed treatment or cancer screening, despite potential selection bias for follow-up status. Efforts should be focused on ensuring timely access to healthcare services, optimizing treatment delivery, and addressing the unique challenges faced by patients with lung cancer during the pandemic to mitigate the impact of the pandemic on lung cancer outcomes and provide clinical care to vulnerable populations.

Impact of the COVID-19 Pandemic on Health Check-ups in 2021 and 2022: A Nationwide Follow-up Survey of Healthcare Facilities in Japan Society of Ningen Dock

Introduction

Preventive programs, including screenings for cancer and diabetes, were disrupted globally due to the coronavirus disease 2019 (COVID-19) pandemic in 2020. We previously conducted a nationwide survey to investigate the initial impact of the pandemic on health check-ups; however, the impact in the second and third years of the pandemic has not yet been elucidated. Here, we conducted a follow-up survey targeting healthcare facilities to evaluate the impact of the pandemic until the end of 2022.

Methods

A questionnaire survey was conducted between December 15, 2022, and February 10, 2023, targeting member facilities of Japan Society of Ningen Dock. The survey consisted of two parts. Part I comprised a web-based questionnaire, in which the facilities were asked about their commitment to COVID-19-related care, precautions against COVID-19, and whether the pandemic had a negative financial impact on the management of health check-ups. In Part II, the facilities were asked about the number of examinees who underwent health check-ups between 2019 and 2022, the proportion of those who needed and adhered to follow-up visits, and the number of cancer cases found between 2019 and 2021.

Results

Of the 1,343 eligible facilities, 885 participated (response rate: 65.9%). The observation that the number of people undergoing mandatory check-ups increased while those undergoing nonmandatory check-ups (e.g., cancer screenings by local governments) decreased in 2021, compared with that of 2019, persisted into 2022. Approximately 60% of the facilities reported a negative financial impact on the management of health check-ups, even in 2022.

Conclusions

In 2022, the pandemic's detrimental effects on health check-ups persisted.

Impact of COVID-19 pandemic on healthcare service use for non-COVID-19 patients in Japan: retrospective cohort study

OBJECTIVES

We aimed to investigate the impact of the first and second waves of the COVID-19 pandemic on healthcare service use by non-COVID-19 patients.

DESIGN

Retrospective cohort study.

SETTING

Hospital-based claims database from anonymised hospitals in Japan.

PARTICIPANTS

Patients (n=785 495) who visited and/or were hospitalised in 26 anonymised hospitals in Japan between January 2017 and November 2020.

OUTCOME MEASURES

We compared changes in the monthly number of hospitalisations (overall or by diagnosis), outpatient visits, endoscopic fibrescopies (EFs), rehabilitations, outpatient chemotherapy treatments, maintenance haemodialysis treatments and outpatient prescriptions between pre-COVID-19 years and the same period in 2020.

RESULTS

The overall number of hospitalisations and outpatient visits decreased by 27% and 22%, respectively, in May 2020, of which the most substantial decrease was observed in the paediatrics department (65% and 51%, respectively). The number of hospitalisations for respiratory diseases, circulatory diseases, malignant neoplasms and digestive diseases decreased by a maximum of 55%, 32%, 10% and 26%, respectively, in 2020. The number of hospitalisations for non-COVID-19 pneumonia in patients aged <16 years, patients aged ≥16 years and patients with asthma decreased by 93%, 43% and 80%, respectively, in May 2020. EFs and outpatient rehabilitations decreased by >30%. In contrast, outpatient chemotherapy and maintenance haemodialysis treatments decreased by <10%, if at all. Outpatient prescriptions decreased by a maximum of 20% in 2020, with the largest decrease observed in drugs for obstructive airway diseases and cough and cold preparations.

CONCLUSIONS

The use of healthcare services by non-COVID-19 patients was most affected during the first wave of the COVID-19 pandemic in May 2020. The number of hospitalisations for respiratory diseases, particularly non-COVID-19 pneumonia and asthma, drastically decreased, while the number of hospitalisations and outpatient chemotherapies for malignant neoplasms or maintenance haemodialysis was less affected.
