Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The primary outcome measure is a patient satisfaction survey regarding their treatment/stay in ED.

Patients with low-risk chest pain will undergo standard assessment. This can include doctor’s assessment, blood tests including cardiac markers such as two troponin blood tests, xrays and CT scans. If the patient has been deemed as ‘low risk’ chest pain (i.e their troponin result is negative and/or other tests are negative) and are likely to be discharged, then they are usually admitted to ED Short stay area while awaiting the repeat troponin blood test in 2 hour’s time.

During the 2 hour period while patients are awaiting their repeat troponin eligible participants will be randomised to the intervention and control groups. The intervention group will undergo a single bedside cardiac ultrasound performed by an Emergency Physician trained in cardiac ultrasound or ED registrar with supervision by Emergency Physician. The ultrasound scan will be performed using Phillips Sparq Ultrasound Machine (Phased array probe) or similar point-of-care ultrasound device, and be performed using a documented protocol. Fidelity to the intervention will be monitored on review of each of the patient scans.

Both intervention and control groups will complete a satisfaction/feedback surveys prior to final discharge .

Statistical methods / analysis
A sample size of 304 participants (152 participants in each group) will be recruited to the study. This is with a study power 0.8 calculated using PS: Power and sample size calculator. This is based on the local ED patient population i.e 71000 total presentations during 2017 of which 10000 were ‘low risk’ chest pain. This study will run until 304 eligible patients are recruited.

Summary
Brief summary
The objective of the study is to assess at whether a bedside Echocardiogram (cardiac ultrasound) improves patient satisfaction of the emergency department performance. Adults with low risk chest pain will be recruited to intervention and control groups. The intervention group will receive a bedside echocardiogram and the outcome measure will be to assess patient satisfaction. An Echocardiogram is not routinely part of the chest pain assessment in ED. The hypothesis of the study is that participants with chest pain who receive an echocardiogram will have higher satisfaction scores compared to those who do not receive an echocardiogram.
