Study summary

During the COVID-19 pandemic, we noticed a rise in complicated appendicitis cases presenting to our medical center. We collected objective data on all patients admitted to the surgical department with appendicitis during February 2020 - March 2020 compared to the same 2 month period in 2019, to understand the pandemic's affect on the rate of complications of acute appendicitis.

Read the detailed description

Coronavirus pandemic (COVID-19) first broke out in Wuhan and Hubei China during december 2019. On 30 January, WHO declared it a Public Health Emergency of International Concern (PHEIC) .

Currently, the number of cases worldwide stands stands at more than 76 million confirmed cases according to the World Health Organization (WHO) records. First documented case in Israel was reported on 21st of february 2020.

During the months of February and April, due to continued rise in confirmed cases, rigid "stay at home" restrictions were issued. These restrictions have had a significant effect on daily life. Under these new "stay at home" policies, many aspects of everyday life were greatly diminished and restricted under threat of heavy fines. This effect also extends to reduction in healthcare seeking. decline in emergency department (ED) visits was reported. A drop in routine cancer screening appointments was reported.

Delayed healthcare seeking also had an affect on the severity of various medical conditions on presentation. fear of the COVID-19 pandemic may have resulted in delayed diagnosis, and therefore higher complication rates in common medical conditions.

acute appendicitis (AA) is among the most common causes of lower abdominal pain leading patients to attend the emergency department. As such, AA could serve as a good indicator for the possible effect that the fear of the COVID-19 pandemic had on patients tendency for late diagnosis and complication rate.

Gomes Laparoscopic Grading System of AA, classifies appendicitis into five laparoscopic grades according to gross morphologic findings during surgical laparoscopy. grades 1 and 2 regarded as non-complicated appendicitis, while grades 3, 4 and 5 regarded as complicated appendicitis.

Following the restrictions imposed during the COVID-19 pandemic, we noticed a rise in complicated appendicitis cases presenting to our medical center. We collected objective data on all patients admitted to the surgical department with appendicitis during February 2020 - March 2020 compared to the same 2 month period in 2019. Data such as the time period from onset of symptoms to presenting to the ED, inflammatory markers, complicated appendicitis (if any), type of complication, post operative complications. We aim to assess whether the "stay at home" restrictions had any adverse effects on severity or outcomes of AA.
