About this study
The Investigators aim to assess;
- whether the changes in managing patients during COVID has reduced the negative appendicectomy rate?
- compare the difference in outcomes of conservatively and surgically managed Acute Appendicitis?
- Whether there uniformity in prescribing postoperative antibiotics with resultant outcomes?
- Whether the incidence of complicated appendicitis has increased?
Read the detailed description
As acute appendicitis is the most commonly managed emergency presentation for surgeons, the investigators aim to assess whether the changes in managing patients during COVID has reduced the negative appendicectomy rate, to compare the difference in outcomes of conservatively and surgically managed Acute Appendicitis? to assess whether there uniformity in prescribing postoperative antibiotics with resultant outcomes? to assess whether the incidence of complicated appendicitis has increased? This will be a single centre retrospective observational study. All the patients presenting in A\&E department with a diagnosis of acute appendicitis to be included. the only exclusion criteria are the age of participants for less than 5 years. The data will be analysed and calculated using SPSS version 23.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
AppendicectomyProcedure or surgery
Laparoscopic or Open Appendicectomy
| Study group | Role | What they receive |
|---|---|---|
| Acute Appendicitis pre-COVID management | Audit of Acute appendicitis management in 2017-18 Receives: Procedure: Appendicectomy | |
| Acute Appendicitis during COVID management | Audit of Acute appendicitis management in 2020 Receives: Procedure: Appendicectomy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Negative Appendicectomy Rate
Negative appendicectomy rate will be calculated to define the benefits of increasing the preoperative scanning in the form of ultrasound, CT scan or both.
Measured: 8 months
Outcomes of Conservative vs Operative Management
The outcomes of both conservatively and operatively managed patients will be assessed to define the best management approach.
Measured: 8 months
Increased Open Appendicectomy Rate
The rate of laparoscopic to open and open appendicectomy rate will be calculated to understand if the surgical practice has been changed during COVID-19 pandemic?
Measured: 8 months
Surgical site infection in patients on antibiotics
The rate of incidence of superficial and deep wound infection will be calculated to define the applicability of use of Antibiotics
Measured: 8 months
Secondary outcomes (1)
Length of Stay
The number of days of postoperative admission in hospital will be assessed while comparing the type of surgery and co-morbidities.
Measured: 8 months

Where is the study taking place?
The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
