简要总结
This study is designed to investigate the acuity of olfactory dysfunction in COVID-19 positive patients in the United Kingdom. In particular defining severity with objective testing and determining if this has any predictive value on the outcome of the SARS CoV-2 infection. In addition, this study will strive to determine duration / natural history of olfactory dysfunction in these patients in respect to a positive SARS CoV-2 diagnosis. It should also demonstrate the impact of olfactory dysfunction on patient Quality of Life (QOL).
详细描述
The main objective of this study is to evaluate olfactory acuity by means of a multidimensional assessment protocol to objectively demonstrate the severity of olfactory dysfunction in patients diagnosed with SARS CoV-2. The University of Pennsylvania Smell Identification Test (UPSIT) will be used to assess olfactory function in newly diagnosed patients and also existing patients longitudinally over a 12-month period. This is to document onset (where possible) and rate of progress of olfactory dysfunction.
In relevant cases, the investigators will correlate their findings with severity of the Acute Respiratory Distress Syndrome (ARDS) arising as a result of the infection - characterised as mild, moderate and severe according to the Berlin classification. The investigators will therefore determine if the degree of olfactory dysfunction correlates in any manner to the severity of ARDS developed in a positive SARS CoV-2 patient and if it offers any prognosticative applications.
The investigators will also examine the impact of the symptom of olfactory dysfunction on patient Quality of Life using two validated tools known as the Questionnaire of Olfactory Disorders for English speakers (eQOD) and the SNOT-22 questionnaire.
Furthermore, outcomes will be explored and stratified in terms of age, gender and ethnicity
