Acute Abdominal Pain

The goal of this clinical trial is to learn if adding an abdominal ultrasound scan to the standard examination helps emergency physicians make a correct diagnosis in adults with acute abdominal pain in the emergency department. The main question it aims to answer is: Does adding an abdominal point of care ultrasound scan to the standard examination increase the number of patients with acute abdominal pain in the emergency department, who get a correct preliminary diagnosis? Researchers will compare patients examined with an abdominal point-of-care ultrasound scan in addition to the standard examination to patients examined with the standard examination alone, to see if adding ultrasound improves diagnostic accuracy. Participants will: * Be randomly assigned to also have an abdominal point-of-care ultrasound scan performed by their doctor, or not * Have their doctor record a preliminary diagnosis and differential diagnosis * Have their medical records reviewed by an independent panel 30 days after their visit, to determine their final diagnosis

The goal of this clinical trial is to learn whether initial assessment by a physician specializing in emergency medicine can improve the care of adults who come to the emergency department with acute abdominal pain or another undifferentiated acute abdominal condition and are referred for surgical assessment. The main questions it aims to answer are: Does initial assessment by an emergency medicine physician reduce the time patients spend in the emergency department? Is this model of care as safe as standard surgical assessment, including the risk of readmission and death within 30 days? Researchers will compare patients who receive their initial assessment from an experienced emergency medicine physician with patients who receive standard care, where the initial assessment is usually performed by a junior surgical physician. Participants will: Be randomly assigned to one of the two models of initial assessment Receive diagnostic tests and treatment according to usual clinical practice Be followed for outcomes such as use of diagnostic imaging, treatment, hospital stay, readmission, and mortality Be asked to complete a short questionnaire about their experience in the emergency department The study does not involve experimental drugs, devices, or procedures. The intervention changes which type of physician is responsible for the initial assessment and management in the emergency department.

The investigators designed this clinical study to evaluate the efficacy and safety of semi-standardized acupuncture and moxibustion combined with compound diclofenac sodium injection in the emergency department (ED) compared with acupuncture or compound diclofenac sodium injection alone.
