“…The number of patients with gastric cancer may increase due to an increase in the number of screening or follow-up endoscopies from September to December, when the number of COVID-19 patients was relatively low, as a result of patients refraining from screening endoscopy before that period. Additionally, the number of esophageal cancer patients at our hospital also showed a similar trend during the same period [ 13 ].…”

Background Little is known about the disadvantages of the coronavirus disease 2019 (COVID-19) pandemic in patients with gastric cancer. This study aimed to examine the negative impact of the COVID-19 pandemic on patients with gastric cancer in the first era in Japan. Methods This retrospective study included 725 patients diagnosed with gastric cancer who visited our hospital between April 2019 and March 2021. The number of patients and their characteristics before and during the COVID-19 pandemic were compared. Results The number of patients diagnosed with gastric cancer during the COVID-19 pandemic decreased by 26.2% (from 417 to 308; p = 0.013) compared to that before the COVID-19 pandemic. There was a significant decrease in cStage I cancer and an increase in cStage III cancer ( p = 0.004). Patients were often symptomatic ( p = 0.029), especially those with stenosis-related symptoms ( p < 0.001) and longer symptom duration ( p < 0.001). The number of endoscopic resections was decreased by 34.8% ( p = 0.005). The number of total gastrectomy was higher than that of partial gastrectomy ( p = 0.021). The median time to treatment was significantly shorter ( p < 0.001). Conclusions In Japan, delays diagnosing patients with gastric cancer, probably due to refraining from consultation, may have resulted in an increase in the diagnosis of advanced-stage cancer. Moreover, an increasing proportion of patients required more invasive gastrectomy. Therefore, it may be necessary to educate patients not to refrain from consultation, even during the COVID-19 pandemic, as it can have a negative impact on treatment, policy decision, and prognosis of gastric cancer.

“…In their retrospective study consisting of 556 patients at a single center in Japan from 2018–2021, Miyawaki et al reported a significant decrease in the number of newly diagnosed EC cases during the first wave of the pandemic. Additionally, they noted an increased proportion of patients diagnosed with distant metastases ( 19 ). Another Japanese study reported 1.9% and 3.1% decreases in overall new cancer diagnoses and new EC diagnoses during the pandemic as compared to the average rates from 2016–2019.…”

“…In this systematic review investigating the impact of resource allocation during the COVID-19 pandemic on patients with EC, several points were noteworthy. For one, reductions in rates of new EC diagnoses were essentially ubiquitous, with up to a 26% reduction noted in some studies ( 6 , 7 , 19 , 20 , 24 , 25 , 28 ). Decreased EC diagnosis was accompanied by inconsistent results regarding the disease severity at presentation.…”

Background The coronavirus disease 2019 (COVID-19) pandemic challenged global infrastructure. Healthcare systems were forced to reallocate resources toward the frontlines. In this systematic review, we analyze the impact of resource reallocation during the COVID-19 pandemic on the diagnosis, management, and outcomes of esophageal cancer (EC) patients. Methods PubMed and Embase were systematically searched for articles investigating the impact of the COVID-19 pandemic on EC patients. Of the 1,722 manuscripts initially screened, 23 met the inclusion criteria. Results Heterogeneity of data and outcomes reporting prohibited aggregate analysis. Reduced detection of EC and considerable variability in disease stage at presentation were noted during the COVID-19 pandemic. EC patients experienced delays in diagnostic and preoperative staging investigations but surgical resection was not associated with greater short-term morbidity or mortality. Modeling the impact of pandemic-related delays in EC care predicts significant reductions in survival with associated economic losses in the coming years. Conclusions Amidst resource scarcity during the COVID-19 pandemic, the multidisciplinary management of patients with EC was affected at multiple stages in the care pathway. Although the complete ramifications of reductions in EC diagnosis and delays in care remain unclear, EC surgery was able to safely continue as a result of collaboration between centers, strict adherence to COVID-19 protective measures, and reallocation of healthcare resources towards the same. Ultimately, when healthcare systems are pushed to the brink, the downstream consequences of resource reallocation require judicious analysis to optimize overall patient outcomes.

“…Emission factors are defined by the quantity of fuel burned while generating energy. Over the years, Japan has increased its use of renewable energy sources for electricity production and resumed nuclear power plant operations [37]. Notably, in the NUH campus, the carbon footprints of factors other than pharmaceuticals and medical supplies have reduced over the years.…”

Influence of COVID-19 on the 10-year carbon footprint of the Nagoya University Hospital and medical research centre

Background: Amidst the climate crisis, a key goal of the medical sector is to reduce its large carbon footprint. Although the Coronavirus disease 2019 (COVID-19) pandemic greatly impacted the medical sector, its influence on carbon footprints remains unknown. Therefore, the aim of this study was to evaluate changes in the carbon footprint of a university hospital with a medical research centre over the past 10 years. Methods: Data on electricity, gas, and water usage, pharmaceutical and medical supply costs, and waste amounts were recorded for Nagoya University Hospital from April 2010 to March 2021. The relevant emission factors were obtained from the Japanese government and the overall monthly carbon footprint was reported according to the Greenhouse Gas Protocol. The effect of the COVID-19 pandemic on the carbon footprint was then compared for three types of emission sources. Moreover, a regression model was used to plot quadratic functions as approximate functions using monthly carbon emissions and monthly average external temperatures. Finally, the monthly carbon footprint was calculated per hospital admission. Results: The overall carbon footprint of the hospital was 73,546 tCO2e in 2020, revealing an increase of 26.60% over the last 10 years. Carbon emissions from electricity consumption represented 26% of total emissions. The individual carbon footprints of pharmaceuticals, medical supplies, waste, and water usage also increased from 2010 to 2020. The overall monthly carbon footprint was positively correlated with the average monthly temperature (R2 = 0.7566, p < 0.001). Compared with 2019, the overall carbon footprint decreased by 2.19% in 2020. Moreover, the monthly carbon footprint per hospital admission increased significantly between 2018 (0.24 tCO2e/admission) and 2020 (0.26 tCO2e/admission) (p = 0.002). Conclusion: The overall carbon footprint of the hospital generally increased over the last decade. During the COVID-19 epidemic in 2020, the carbon footprint decreased slightly, likely because of the reduced number of patients. However, the carbon footprint per admission increased, which was attributed to more complicated patient backgrounds because of the ageing population. Therefore, evaluation of carbon emissions in the medical sector is urgently required in order to act on the climate crisis as soon as possible.
