BACKGROUND: Acute appendicitis is the most common cause of acute abdomen. During the pandemic, to contain the spread of COVID-19, there were some integral changes in the medical processes based on the pandemic prevention policy, especially regarding emergency surgery. This study was conducted to investigate whether this pandemic also impacted the decision-making for both patients and medical personnel along with the treatment outcomes. METHODS: Patients of age 18 years or older who were diagnosed clinically and radiologically with acute appendicitis between Jan 1, 2017, and Dec 31, 202,0 were reviewed. The data of 1991 cases were collected and used for this study. Two groups were formed, one group before and the other group after the outbreak. The gathered data included gender, age, appendiceal fecalith, outcomes of treatment, and long-term outcomes of non-operation (8 months follow-up). We also collected details of surgical cases from the above two groups. This data also included age, gender, appendiceal fecalith, fever, jaundice, length of onset before presenting to an emergency department (ED), anesthesia, surgery, white cell count, pathology, complications, and length of stay. We compared the above data respectively and analyzed the differences. RESULTS: Compared to the period before the outbreak, patient visits for acute appendicitis remarkably dropped (19.8%), but surgical cases showed no change (dropped by roughly 5%). There were significant differences (P < 0.05) in failure of non-operation(after the pandemic 8.31% vs. before pandemic 3.22%), interval appendectomy(after pandemic 6.29% vs. before pandemic 12.84%), recurrence(after pandemic 23.27% vs. before pandemic 14.46%), and outcomes of recurrence. There was a significant difference (P < 0.05) in anesthesia method, surgery way, and complications( before pandemic 4.15% vs. after pandemic9.89% P < 0.05) in patients who underwent the surgery. There was no statistical difference (P > 0.05) concerning age, gender, fever, jaundice, appendiceal fecalith, white cell count, and length of onset before presenting to the ED. CONCLUSION: The current pandemic prevention policy is very effective, but some decision-making processes of doctor-patient have changed in the context of COVID-19 pandemic, that further influenced some treatment outcomes and might lead to a potential economic burden. It is essential to address the undue concern of everyone and optimize the treatment process.

BACKGROUND: The progression of coagulation in COVID-19 patients with confirmed discharge status and the combination of autopsy with complete hemostasis parameters have not been well studied. OBJECTIVE: To clarify the thrombotic phenomena and hemostasis state in COVID-19 patients based on epidemiological statistics combining autopsy and statistical analysis. METHODS: Using autopsy results from 9 patients with COVID-19 pneumonia and the medical records of 407 patients, including 39 deceased patients whose discharge status was certain, time-sequential changes in 11 relevant indices within mild, severe and critical infection throughout hospitalization according to the Chinese National Health Commission (NHC) guidelines were evaluated. Statistical tools were applied to calculate the importance of 11 indices and the correlation between those indices and the severity of COVID-19. RESULTS: At the beginning of hospitalization, platelet (PLT) counts were significantly reduced in critically ill patients compared with severely or mildly ill patients. Blood glucose (GLU), prothrombin time (PT), activated partial thromboplastin time (APTT), and D-dimer levels in critical patients were increased compared with mild and severe patients during the entire admission period. The International Society on Thrombosis and Haemostasis (ISTH) disseminated intravascular coagulation (DIC) score was also high in critical patients. In the relatively late stage of nonsurvivors, the temporal changes in PLT count, PT, and D-dimer levels were significantly different from those in survivors. A random forest model indicated that the most important feature was PT followed by D-dimer, indicating their positive associations with disease severity. Autopsy of deceased patients fulfilling diagnostic criteria for DIC revealed microthromboses in multiple organs. CONCLUSIONS: Combining autopsy data, time-sequential changes and statistical methods to explore hemostasis-relevant indices among the different severities of the disease helps guide therapy and detect prognosis in COVID-19 infection.
