Role of carotid duplex imaging in carotid screening programmes - an overview.

ABSTRACT: BACKGROUND: Stroke is the third most common cause of death in the UK and the largest single cause of severe disability. Each year more than 110,000 people in England suffer from a stroke which costs the National Health Service (NHS) over GBP2.8 billion. Thus, it is imperative that patients at risk be screened for underlying carotid artery atherosclerosis. AIM: To assess the role of carotid ultrasound in different carotid screening programmes. METHODS: A literature overview was carried out by using PubMed search engine, to identify different carotid screening programmes that had used ultrasound scan as a screening tool. RESULTS: It appears that the carotid ultrasound is an effective method for screening carotid artery disease in community as it effectively predicts the presence of stenosis with high accuracy. There is a need for primary care to recommend high risk patients for regular screening, to reduce stroke and transient ischemic attack (TIA) related morbidity and mortality. CONCLUSION: Screening programmes using carotid ultrasonography contribute to public health awareness and promotion which in long term could potentially benefit in disease prevention and essentially promote better standards of healthcare.

Project description:This study aimed to describe the duplex ultrasound (DUS) findings associated with carotid restenosis after carotid endarterectomy (CEA) and to determine whether carotid restenosis is associated with the clinical outcomes of CEA. Between January 2007 and December 2016, a total of 660 consecutive patients who underwent 717 CEAs were followed up at our hospital with DUS surveillance for at least 3 years after CEA. These patients were analyzed retrospectively for this study. Following CEA, restenosis was defined as the development of ≥50% stenosis, diagnosed on the basis of DUS findings of the luminal narrowing and velocity criteria. The study outcomes were defined as restenosis of the ipsilateral carotid artery after CEA and late (>30days) fatal or nonfatal stroke ipsilateral to the carotid restenosis. During the median follow-up period of 74 months, the restenosis incidence was 2.8% (20/717), and there were 2 strokes (2/20, 10%) ipsilateral to the restenosis after CEA; reintervention was performed for 11 patients with carotid restenosis (55%). Within 2 years after CEA, restenosis was identified in 9 cases (45%, 9/20), and 8 reinterventions (72.7%, 8/11) were performed. According to DUS findings, the morphologic characteristics of carotid restenosis were different from the preoperative plaque morphology. Among the 20 carotid restenosis cases, we observed the following DUS patterns: homogenous isoechoic restenosis (n = 14, 70%), homogenous hypoechoic (n = 2, 10%), isoechoic with hypoechoic surface (n = 3, 15%), and hypoechoic with isoechoic surface (n = 1, 5%). Although 9 carotid restenosis patients received prophylactic reintervention to mitigate the progression of restenosis, the 2 symptomatic restenosis patients had isoechoic lesions with hypoechoic surfaces on DUS. On Kaplan-Meier survival analyses, in terms of stroke-free survival rates, there was a higher risk of stroke among patients with carotid restenosis compared with patients without restenosis, with a non-significant trend (P = 0.051). In conclusion, most carotid restenoses were identified within 2 years after CEA, and there was a non-significant trend toward a higher risk of stroke among patients with carotid restenosis.

Project description:ObjectivesSuccessful lung cancer screening delivery requires sensitive, timely reporting of low-dose computed tomography (LDCT) scans, placing a demand on radiology resources. Trained non-radiologist readers and computer-assisted detection (CADe) software may offer strategies to optimise the use of radiology resources without loss of sensitivity. This report examines the accuracy of trained reporting radiographers using CADe support to report LDCT scans performed as part of the Lung Screen Uptake Trial (LSUT).MethodsIn this observational cohort study, two radiographers independently read all LDCT performed within LSUT and reported on the presence of clinically significant nodules and common incidental findings (IFs), including recommendations for management. Reports were compared against a 'reference standard' (RS) derived from nodules identified by study radiologists without CADe, plus consensus radiologist review of any additional nodules identified by the radiographers.ResultsA total of 716 scans were included, 158 of which had one or more clinically significant pulmonary nodules as per our RS. Radiographer sensitivity against the RS was 68-73.7%, with specificity of 92.1-92.7%. Sensitivity for detection of proven cancers diagnosed from the baseline scan was 83.3-100%. The spectrum of IFs exceeded what could reasonably be covered in radiographer training.ConclusionOur findings highlight the complexity of LDCT reporting requirements, including the limitations of CADe and the breadth of IFs. We are unable to recommend CADe-supported radiographers as a sole reader of LDCT scans, but propose potential avenues for further research including initial triage of abnormal LDCT or reporting of follow-up surveillance scans.Key points• Successful roll-out of mass screening programmes for lung cancer depends on timely, accurate CT scan reporting, placing a demand on existing radiology resources. • This observational cohort study examines the accuracy of trained radiographers using computer-assisted detection (CADe) software to report lung cancer screening CT scans, as a potential means of supporting reporting workflows in LCS programmes. • CADe-supported radiographers were less sensitive than radiologists at identifying clinically significant pulmonary nodules, but had a low false-positive rate and good sensitivity for detection of confirmed cancers.

Project description:IntroductionA global variation in the pharmacy support personnel training programmes has been observed. The objective of this scoping review is to map out global evidence available on the pharmacy support personnel training programme characteristics, and interface between knowledge, practice and regulatory requirements.Methods and analysisThe scoping review will be undertaken by two independent reviewers. Peer-reviewed journal articles of any study design and grey literature will be included with no publication time limit. All literature published in English focusing on pharmacy support personnel training programmes, entry-level certification requirements, ongoing professional development and apprenticeship will be included. We will search MEDLINE (EBSCOhost), PubMed, CINAHL (EBSCOhost), Web of Science, Academic Search Complete, (EBSCOhost) and Dissertation and Thesis (ProQuest), ProQuest Dissertation and Thesis Global and Google Scholar, and reference list of all included studies. We will also search grey literature from websites of international professional regulatory bodies and associations. All studies that meet the inclusion criteria will be imported into a reference management package (EndNote V.20) that facilitates study selection, screening and de-duplication. Data will be extracted by two independent reviewers using a jointly developed and piloted data charting form. Data items will include skills, knowledge, competencies, admission criteria, content, duration, qualification options, accreditation status, delivery models and approaches. Data extracted from the included studies will be collated, and quantitative results presented using descriptive statistics such as percentages, tables, charts and flow diagrams as appropriate. A narrative account of findings from the literature will be presented following qualitative content analysis of the extracted information using NVivo V.12. Quality appraisal of included studies will not be assessed as the purpose of the scoping review is to give a descriptive global overview of the pharmacy support personnel training programmes, and evidence will also be sourced from grey literature.Ethics and disseminationNo ethical approval is needed for this study as it does not include animals or human participants. The study findings will be disseminated electronically and in print with presentations done at relevant platforms, that is, in peer-reviewed journals, in print and in conferences.RegistrationOpen Science Framework (ofs.i0/r2cdn; registration DOI: https://doi.org/10.17605/OSF.IO/F95MH; internet archive link: https://archive.org/details/osf-registrations-f95mh-v1; registration type: OSF-Standard Pre-Data Collection Registration).
