P133 Measuring oxygen saturation on follow up chest X-Ray and resolution of radiological changes at 6 to 12 weeks post COVID pneumonitis

Abstract

P133 Table 1Characteristics and outcome of patients with COVID-19 on admission and follow up N Males Females Mean age (years) SD Total admitted patients* 302 165 137 64 20.65 • Patients with abnormal CXR on admission 207 124 83 67.5 16.74 • Patients with normal CXR on admission 73 31 42 62.9 20.71 • No CXR available at admission 22 10 12 65 22.42 Follow up CXR** • Follow up CXR done 155 93 62 65 24 • Follow up CXR normal/baseline changes 122 70 52 62.7 15.8 • Follow up CXR abnormal 33 23 10 68.3 13.6 *Total local population in Guildford and Waverly 225,000 as per 2017 census.** 6–12 weeks follow up CXR was not done in 52 patients due to multiple patient factors (e.g. mortality, patient did not attend). Mortality rate 7% (N: 21) at time of data collection.ConclusionOur data shows that the majority of patients with COVID pneumonitis had a normal CXR at 6–12 weeks post discharge. However, a significant proportion of patients still have on-going radiological changes. There was no correlation between target SpO2 and ongoing radiological changes. Patients with normal follow-up CXR were significantly younger than those with persistent changes. We continue to study this group of patients and post COVID sequelae.Referencehttps://www.brit-thoracic.org.uk/covid-19/covid-19-information-for-the-respiratory-community/
