What is Trip?

Trip is a clinical search engine designed to allow users to quickly and easily find and use high-quality research evidence to support their practice and/or care.

Trip has been online since 1997 and in that time has developed into the internet’s premier source of evidence-based content. Our motto is ‘Find evidence fast’ and this is something we aim to deliver for every single search.

As well as research evidence we also allow clinicians to search across other content types including images, videos, patient information leaflets, educational courses and news.

Superb Micro-vascular Imaging (SMI): a Doppler ultrasound technique with potential to identify, classify, and follow up endoleaks in patients after Endovascular Aneurysm Repair (EVAR) The aim of the study was to assess the effectiveness of Superb Micro-vascular Imaging (SMI) as an alternative to Contrast-Enhanced Ultrasound (CEUS) and Computed Tomography Angiography (CTA) for endoleak detection and classification in patients followed up after endovascular abdominal aortic aneurysm repair (EVAR (...) ).From May 2015 to January 2017, 30 patients underwent post-EVAR follow-up with Color Doppler Ultrasound (CDUS), CEUS, SMI, and CTA examinations. Aneurysmal sac diameter and graft patency were evaluated; endoleaks were identified and classified. Sensitivity, specificity, and accuracy values were calculated for each of the four diagnostic methods of endoleak detection. A percentage of agreement and Cohen's Kappa coefficient were calculated for comparison of methods in terms of endoleak

Comparison of Ultrasound-Guided Local Ozone (O2-O3) Injection vs Corticosteroid Injection in the Treatment of Chronic Plantar Fasciitis: A Randomized Clinical Trial Plantar fasciitis (PF) is one of the most common causes of heel pain. The affected area is often close to the attachment of plantar fascia to calcaneus bone. The purpose of this study was to compare the effects of ozone (O2-O3) injection to corticosteroid injection under ultrasound guidance for the treatment of chronic PF.Randomized (...) thickness at insertion and 1 cm distal to its insertion into the calcaneus via ultrasound imaging.Intragroup changes showed significant improvement in pain, functional parameters, and sonographic findings in both groups (P < 0.05). Pain reduction (both daily and morning) and daily activity improvement were better in the corticosteroid group two weeks after injection; however, at 12 weeks, the ozone (O2-O3) group had significantly more improvement (P = 0.003, P = 0.001, and P = 0.017, respectively).Both

Ultrasound could help diagnose giant cell arteritis Ultrasound could help diagnose giant cell arteritis Discover Portal Discover Portal Ultrasound could help diagnose giant cell arteritis Published on 14 February 2017 doi: Ultrasound may aid giant cell arteritis diagnosis in people referred from the community. It is less invasive than biopsy and might provide quicker results than a biopsy, but its role and place in the diagnostic pathway remain unclear. Giant cell arteritis is a disease (...) of medium to large sized arteries and can lead to a range of eye, brain and other complications. Sudden or gradual blindness is a real risk and anyone with suspected giant cell arteritis is referred to hospital for a biopsy and started on high dose steroids. This NIHR-funded study found that ultrasound correctly picks up more cases than biopsies, but also falsely identifies some people who do not have the condition. Biopsies falsely diagnose giant cell arteritis in fewer people without the condition

A broken tibia is the most common long bone fracture. These fractures can take six months or longer to heal and are particularly vulnerable to non-union, when the broken pieces of bone fail to grow back together. LIPUS is commonly used in North America after fracture surgery with the intention of speeding up healing and preventing non-union and is available in the UK. LIPUS involves applying ultrasound waves to skin over the fracture using a wand or probe and gel, similar to those used for pregnancy
