Clinical Trial Summary

The overall project goal is to conduct a pilot randomized clinical trial of operative (laparoscopic appendectomy) vs nonoperative (antibiotic) management of uncomplicated acute appendicitis for vulnerable populations. Specifically, the elderly, non-English speakers, and those with economic vulnerability (low socioeconomic status and/or manual labor jobs without a non-weight lifting aspect), are three vulnerable population subsets identified. This pilot trial will provide critical preliminary data for planning and conducting a larger multi-site randomized trial.

Description:

The study would involve consented subjects, once confirmed eligible to proceed after screening, will be randomly assigned to two arms: - Group 1 - Operative Group - Operation will be performed to remove appendix. - Group 2 - Non-operative group - No operation will be performed, and instead the subject will receive intra-venous (IV) antibiotics, transitioned to by mouth (oral) antibiotics, for treatment of appendicitis. Aside from the routine hospital care, participants will be asked to fill out a survey for cognitive function (CAM Assessment Form), pain (Visual Analog Scale), and quality of life at the start and end of participant's hospital stay, 1-2 weeks after discharge, and again at 6 weeks after discharge from the initial hospital visit. Participants will also be asked to participate in a qualitative interview, either by virtual visit, site visit, or phone call, at 1-2 weeks and again at about 6 weeks after discharge from the hospital. Each interview will be approximately 20-30 minutes of the participant's time.

Intervention

Procedure:
• Laparoscopic appendectomy
Subjects will receive surgery (using 3 port Laparoscopic appendectomy) to remove appendix

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Feasibility of the intervention as measured by the proportion of enrolled participants retained in this study	Feasibility of the intervention is measured by the proportion of enrolled participants who are randomized and retained in this study	12 months post treatment
Primary	Feasibility of the intervention as measured by the number of complications or adverse events	Feasibility of the intervention is measured by the number of complications or adverse events encountered by participants while enrolled in this study	12 months post treatment
Secondary	Feasibility of the intervention as measured by total length of hospital stay (Antibiotics Group)	Feasibility of the intervention is measured by total number of days in inpatient hospital stay for the IV antibiotics group post treatment	the day of discharge (approx. 1-3 days post treatment)
Secondary	Feasibility of the intervention as measured by total length of hospital stay (Operative Group)	Feasibility of the intervention is measured by total number of days in inpatient hospital stay for the Operative group post laparoscopic appendectomy	the day of discharge (approx. 0-2 days post treatment)
Secondary	Feasibility of the intervention as measured by the number of hospital readmissions or emergency room visits	Feasibility of the intervention is measured by the count of the number of hospital readmissions or emergency room visits by the participants at 1-2 weeks post-discharge	1-2 weeks post-discharge
Secondary	Feasibility of the intervention as measured by the number of hospital readmissions or emergency room visits	Feasibility of the intervention is measured by the count of the number of hospital readmissions or emergency room visits by the participants at 6 weeks post-discharge	6 weeks post-discharge
Secondary	Feasibility of the intervention as measured by QoL surveys	Feasibility of the intervention is measured by administering Quality of Life (QoL) surveys using Quality of Recovery-40 questionnaire. This is a self-rated questionnaire for early postoperative quality of recovery and health status of patients. Possible scores range from 1 to 5, where higher scores indicate better quality of life (i.e., 1 = very poor and 5 = excellent)	prior to discharge home (approx. 4-6 hours post treatment)
Secondary	Feasibility of the intervention as measured by QoL surveys	Feasibility of the intervention is measured by administering Quality of Life (QoL) surveys using Quality of Recovery-40 questionnaire. This is a self-rated questionnaire for early postoperative quality of recovery and health status of patients. Possible scores range from 1 to 5, where higher scores indicate better quality of life (i.e., 1 = very poor and 5 = excellent)	1-2 weeks post-discharge
Secondary	Feasibility of the intervention as measured by QoL surveys	Feasibility of the intervention is measured by administering Quality of Life (QoL) surveys using Quality of Recovery-40 questionnaire. This is a self-rated questionnaire for early postoperative quality of recovery and health status of patients. Possible scores range from 1 to 5, where higher scores indicate better quality of life (i.e., 1 = very poor and 5 = excellent)	6 weeks post-discharge
Secondary	Change in pain score from baseline as measured by visual analog pain scale at prior to discharge home (approx. 4-6 hours post treatment)	Change in pain score from baseline is measured by visual analog pain scale at prior to discharge home (approx. 4-6 hours post treatment). Possible scores range from 0-10, where 0= no pain and 10= worst pain.	Baseline, prior to discharge home (approx. 4-6 hours post treatment)
Secondary	Change in pain score from baseline as measured by visual analog pain scale at 1-2 weeks post discharge	Change in pain score from baseline is measured by visual analog pain scale at weeks post discharge.

If Inattention and at least one other item ( regarding acute change in mental status; inattention) in Box 1 of the questionnaire are checked and at least one item (regarding disorganized thinking; altered level of consciousness) in Box 2 of the questionnaire is checked, then a diagnosis of delirium is suggested.

Frail scale scores range from 0-5 (i.e., 1 point for each component; 0=best to 5=worst) and represent frail (3-5), pre-frail (1-2), and robust (0) health status.	Baseline
