ABSTRACT
Background: The Coronavirus Disease 2019 (COVID-19) pandemic has necessitated the alteration of the organization of entire hospitals to try to prevent them from becoming epidemiological clusters. The adopted diagnostic tools lack sensitivity or specificity. Objectives: The aim of the study was to create an easy-to-get risk score (Ri.S.I.Co., risk score for infection with the new coronavirus) developed on the field to stratify patients admitted to hospitals according to their risk of COVID-19 infection. Methods: In this prospective study, we included all patients who were consecutively admitted to the suspected COVID-19 department of the Bufalini Hospital, Cesena (Italy). All clinical, radiological, and laboratory predictors were included in the multivariate logistic regression model to create a risk model. A simplified model was internally and externally validated, and two score thresholds for stratifying the probability of COVID-19 infection were introduced. Results: From 11th March to 5th April 2020, 200 patients were consecutively admitted. A Ri.S.I.Co lower than 2 showed a higher sensitivity than SARS-Cov-2 nucleic acid detection (96.2% vs. 65.4%;P < 0.001). The presence of ground-glass pattern on the lung-CT scan had a lower sensitivity than a Ri.S.I.Co lower than 2 (88.5% vs. 96.2%;P < 0.001) and a lower specificity than a Ri.S.I.Co higher than 6 (75.0% vs. 96.9%;P < 0.001). Conclusions: We believe that the Ri.S.I.Co could allow to stratify admitted patients according to their risk, preventing hospitals from becoming the main COVID-19 carriers themselves. Furthermore, it could guide clinicians in starting therapies early in severeonset cases with a high probability of COVID-19, before molecular SARS-CoV-2 infection is confirmed.
ABSTRACT
Objective: Evaluate the impact of Covid-19 in a critical area and analyze the changes in the daily activities in an Emergency Department of a tertiary COVID-Hospital. Methods: We reported and compared the surgical procedures performed for acute appendicitis and acute cholecystitis between two periods (March and April 2019 and March and April 2020) at Emergency Surgery Department of Parma University Hospital, a tertiary COVID-Hospital. Results: A total of 72 patients underwent surgery between March and April 2019 and 36 between March and April 2020 for acute appendicitis and cholecystitis. The average length of stay was comparable in the two considered years for LA (4.23±1.69 days in 2019 versus 4.5±2.33 days in 2020). The average length of stay in patients with acute cholecystitis was 5.9±3.8 days in 2019 and 8.23±5.5 days in 2020(P=0.038). The average hospitalization was comparable with 2019 data (5.62±3.77 days)n March 2020;whereas, April 2020 was statistically significantly longer 10.5±6 days (P= 0.023). Conclusions: Half of the emergency centers reported a drop in the overall number of urgent cases as confirmed in our department, where the number of total appendicectomy and cholecystectomy was halved comparing the two months in 2019 and 2020, 72 operations in 2019 versus 36 operations in 2020.During the pandemic, the confidence of the population to the healthcare systems was poor, and this can explain the delayed access to the emergency department of patients who suffered from an acute illness.
ABSTRACT
INTRODUCTION: Several articles have been published about the reorganisation of surgical activity during the COVID-19 pandemic but few, if any, have focused on the impact that this has had on emergency and trauma surgery. Our aim was to review the most current data on COVID-19 to provide essential suggestions on how to manage the acute abdomen during the pandemic. METHODS: A systematic review was conducted of the most relevant English language articles on COVID-19 and surgery published between 15 December 2019 and 30 March 2020. FINDINGS: Access to the operating theatre is almost exclusively restricted to emergencies and oncological procedures. The use of laparoscopy in COVID-19 positive patients should be cautiously considered. The main risk lies in the presence of the virus in the pneumoperitoneum: the aerosol released in the operating theatre could contaminate both staff and the environment. CONCLUSIONS: During the COVID-19 pandemic, all efforts should be deployed in order to evaluate the feasibility of postponing surgery until the patient is no longer considered potentially infectious or at risk of perioperative complications. If surgery is deemed necessary, the emergency surgeon must minimise the risk of exposure to the virus by involving a minimal number of healthcare staff and shortening the occupation of the operating theatre. In case of a lack of security measures to enable safe laparoscopy, open surgery should be considered.
