RESUMO
BACKGROUND: The COVID-19 pandemic caused significant disruptions to healthcare systems around the world, due to both high resource utilization and concern for disease spread. Delays in non-emergent surgeries have also affected chronic disease management, including that of benign brain tumors such as meningiomas and pituitary adenomas. To evaluate the effect of COVID-19 infection on benign brain tumor resection rates and subsequent perioperative and inpatient outcomes, this study utilized the 2020 National Inpatient Sample (NIS) to investigate rates of surgical resection, time to surgery, and mortality among benign brain tumor patients with and without COVID-19. METHODS: Patient data from April 2020 to December 2020 was extracted from the NIS. Confirmed COVID-19 diagnosis was identified using the ICD-10 diagnosis code U07.1. Patients with benign neoplasms of the cerebral meninges, cranial nerves, pituitary gland, craniopharyngeal duct, and brain were included in the study. Patient socio-demographics, hospital characteristics, and clinical comorbidities were obtained. Outcome variables included rates of surgical resection, time to surgery, in-hospital mortality, length of stay, and discharge disposition. RESULTS: The study analysis consisted of 13,053 patients with benign intracranial neoplasms who met inclusion criteria; 597 (4.6%) patients were COVID-19 positive. Patients with COVID-19 were more likely to be older and male than COVID-19 negative patients. Patients with COVID-19 had increased overall likelihood of mortality (OR 2.36, 95% CI 1.72-3.25, p < 0.0001). Even when controlling for sociodemographic/hospital factors and comorbidities, COVID-19 positive patients had a significantly longer time to surgery (8.7 days vs. 0.9 days, p < 0.0001) than COVID negative patients, and were associated with a decreased likelihood of undergoing surgery on index admission overall (OR 0.17, 95% CI 0.10-0.29, p < 0.0001). CONCLUSIONS: As expected, COVID-19 infection was associated with worse inpatient outcomes in effectively all measured categories, including longer time to surgery, decreased likelihood of receiving surgery on index admission, and increased likelihood of in-hospital mortality. These findings emphasize the effect that COVID-19 has on other aspects of patient care and highlight the importance of appropriate avenues of care for patients who are COVID-19 positive. Although the COVID-19 pandemic is no longer a public health emergency, understanding the pandemic's impact on outcome for these patients is essential in efficient triage and optimizing treatment for these patients in the future. Further study is needed to elucidate causal relationships on the outcomes of benign brain tumor patients.
