Clinical Trial for a Outpatient Clinical Management for Complicated Acute Appendicitis (ASI2)

Randomized Clinical Trial to Test the Efficacy and Safety of Outpatient Clinical Management of Urgent Laparoscopic Appendectomy in Complicated Acute Appendicitis

The aim of this study is to evaluate the safety and efficacy of outpatient management of complicated acute appendicitis. For this purpose, a randomized clinical trial was designed. Selected patients who have undergone surgery for acute appendicitis are randomized into two groups. One group with hospitalization and another group without admission.

Study Overview

• Status: Not yet recruiting
• Conditions: Acute Appendicitis; Appendicitis Perforated; Appendicitis Suppurative
• Intervention / Treatment: Behavioral: Hospitalization; Behavioral: Outpatient

Detailed Description

The aim of this study is to evaluate the efficacy and safety of outpatient management of laparoscopic appendicectomy in complicated acute appendicitis.

This was a single center randomized controlled clinical trial consisting in 2 treatment groups. Patients were recruited in University Hospital of Tarragona Joan XXIII of Spain.

All patients admitted in the emergency department at University Hospital of Tarragona Joan XXIII with acute appendicitis diagnosis were likely to enter in the study.

All patients who met the inclusion criteria and none of the exclusion criteria were admitted to the study for emergency surgery.

In order to avoid the biases a unique anesthetic and surgical protocol were established for both groups.

Once Laparoscopic appendicectomy was performed the patients were randomly assigned to the hospitalization group or outpatient group.

Patients in the hospitalization group were admitted in the hospitalization ward. Patients in the outpatient group were referred to the day-surgery unit where they were discharged according to ALDRETE criteria.

The primary endpoint was the length of hospital stay (LHS). The length of hospital stay was calculated from the day and hour of admission in the surgical area to the day and hour of discharge, based on the hours of hospital stay. Secondary endpoints included the failures of the outpatient management, readmissions and the hospitals cost

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: outpatient group; Patients in the outpatient group , once operated, were transferred to the surgery unit without admission and were later discharged home if they met the ALDRETE criteria in less than 23 hours after the intervention (following the surgery criteria without admission stages). If the patient was operated during the night shift, following the advice of major outpatient surgery where overnight stays are allowed, the patient was admitted to the post-anesthetic recovery unit and discharged the next day, always in less than 23 hours. In case of being discharged after 23 hours or not meeting ALDRETE criteria, it was considered a failure of the outpatient treatment.	Behavioral: Outpatient; Once the patient was operated and an uncomplicated appendicitis was confirmed, the patient was randomized to one of the two experimental branches: the hospitalization group (HG) or outpatient group (OG). Patients in the OG were referred to the day- surgery unit where they were discharged according to ALDRETE criteria.
Active Comparator: hospitalization group; Patients in the hospitalization group, once the surgical intervention was finished, were transferred to the postoperative recovery unit and later they were discharged to the usual hospital ward. Patients received adequate intravenous fluid resuscitation based on their individual hemodynamic parameter and fluid balance, and they received analgesia according to personal requirement. In the hospital ward, the usual patient management protocols were followed until a complete recovery and consequently discharged according to the usual criteria	Behavioral: Hospitalization; Once the patient was operated and an uncomplicated appendicitis was confirmed, the patient was randomized to one of the two experimental branches: the hospitalization group (HG) or outpatient group (OG). In this group, were admitted in the hospitalization ward

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
length of hospital stay (LHS)	The length of hospital stay (LHS) was calculated from the date and time of urgent appendectomy surgery to the date and time of hospital discharge, based on the hours of hospital stay (assessed up to 5 days)	up to 5 days

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
failures of the outpatient management	Once the patients were discharged home, they were evaluated for emergency room visit. From the date of hospital discharge to the day of emergency room visit. The presence of a emergency room visit is considered as a Failure of the outpatient management.	assessed up to 30 days
readmissions	Once the patients were discharged home, they were evaluated for readmission to the hospital ward. From the date of hospital discharge to the day of readmission to the hospital ward. The re-admission to the hospitalization ward was considered a readmission.	assessed up to 30 days
hospitals cost	The economic costs of both clinical managements were evaluated until the end of the study, a mean of 1 year. For the study, the direct and indirect costs of laparoscopic surgery, consumable material, economic expenses in the hospital ward, and the cost of the price of the emergency room visit were evaluated. The hospital's economic department was contacted and they calculated the cost in euros per patient. Each group was evaluated separately and a comparison was made	through study completion, an average of 1 year
