There have been significant changes in primary and secondary care services during COVID-19 pandemic and the “stay at home, save lives, protect the NHS” message during the COVID-19 pandemic may have impacted healthcare seeking behaviour. We aim to determine the pandemic's effect on emergency presentations of lung cancer.Method: Data was retrieved from our trust cancer database for six months before the first COVID-19 lockdown in England (23/09/19–22/03/20) and six months after (23/03/20–22/09/20). EP of lung cancer was defined as new diagnosis of new lung cancer after emergency department or acute medical unit attendance.Data was analysed for patient characteristics and presentation route. The Chi-square test was used for statistical analysis.Results: 291 patients were diagnosed with lung cancer in the 6 months prior to COVID-19 lockdown and 271 post-lockdown. Table 1 shows a significantly increased EP from 64 to 86 patients post-lockdown together with a significant increase in hospital versus primary care referrals to the lung cancer service.

We believe this may be related to altered primary care service, patients not wanting to access healthcare ‘unnecessarily’ and thus not presenting until symptoms trigger emergency admission.FootnotesCite this article as: European Respiratory Journal 2021; 58: Suppl. 65, PA3848.This abstract was presented at the 2021 ERS International Congress, in session “Prediction of exacerbations in patients with COPD”.This is an ERS International Congress abstract.
