Clinical Presentation, Management and Outcome of Staffs with COVID-19 Disease: a large tertiary Oil and Refinery Grand Hospital Study

Abstract

Objective The aim of the present study was to assess clinical characteristics, managing and controlling, and in-hospital outcome of COVID-19 among oil refinery workers in a single referral center. Methods This cross-sectional study was conducted in a non-COVID single referral center from March to August 2020. At the Naft grand Hospital, the COVID-19 specimen collection and molecular detection unit was established with staff trained to collect suitable samples (sufficiently deep swabs), storage, packaging, and transportation. The diagnosis of COVID-19 infection (SARS-CoV-2) was confirmed by real-time reverse transcription polymerase chain reaction (RT-PCR) assay. Results Overall, 500 patients with confirmed COVID-19 infection were included, of which the most common comorbidities were hypertension (52.2%) and diabetes (45.6%). Moreover, 298 patients (59.6%) had one to three comorbidities, 148 patients (29.6%) had four to six cases, and two patients (0.4%) had seven and more comorbidities. Finally, 23 people (4.6%) have cancer and 206 people (41.2%) have other diseases. 390 (78.8%) received Kaletra, and 387 (78.02%) receive Azithromycin. Overall, PCR test result was positive in 377 (75.4%) patients, computed tomography scan (CT-scan) test was positive in 413 (82.6%) patients, and CRP test had positive result in 335 patients (67%) patients. Conclusion Most referred cases were survivors with mild to moderate symptoms, and a few of them were unfortunately non-survivor. This could be due to those people with mild COVID-19 symptoms may respond well to the treatment and institutional isolation. Thus, good and evidence-based clinical care combined with strong public health interventions will save the lives of thousands, if not millions, worldwide.
