A Scoping Review of Measurement Tools Evaluating Awareness and Disease-Related Knowledge in Peripheral Arterial Disease Patients

BACKGROUND

Peripheral arterial disease (PAD) is the third leading cause of atherosclerotic cardiovascular morbidity worldwide, with high prevalence and associated complications, and is often overlooked and undertreated. Research has shown that there is a profound lack of PAD-related knowledge and awareness; additionally, information sources are not often reliable and accessible. The objective of this scoping review was: (1) to identify and critically appraise instruments that measure patients' disease-related knowledge/awareness about PAD, and (2) to characterize the current state of knowledge/awareness levels among these patients.

METHODS

This systematic review was conducted and reported in accordance with the PRISMA statement. Six databases (APA PsycInfo, CINAHL Ultimate, Embase, Emcare Nursing, Medline ALL and Web of Science Core Collection) were searched, and search strategies were developed utilizing the PICO framework. Potential studies of any methodological design were considered for inclusion through a snowball hand search. Data from the included articles were extracted by a reviewer, and the extraction accuracy was independently cross-checked by another author.

RESULTS

The initial database search yielded 9832 records, of which sixteen studies (thirteen quantitative and three qualitative) were included. Only three questionnaires had their psychometric properties assessed. Questionnaire items focused on the following topics: definition/characteristics, risk factors/causes, treatment, complications, and personal issues regarding the perception/management of the disease. Overall, knowledge/awareness about PAD was low among patients.

CONCLUSIONS

This study identified major gaps in PAD education, including the lack of availability of a validated measurement tool addressing all educational topics relevant to care and low knowledge/awareness of patients about their condition.

A scoping review of vascular surgery education in the medical school curriculum

OBJECTIVE

Despite the high burden of vascular disease that is assessed, investigated, and managed by generalists, no specific medical school curriculum is in use for vascular surgery (VS). In the present scoping review, we aimed to map the available evidence on the provision of VS education in the medical school curriculum worldwide.

METHODS

The present review was conducted in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analysis) extension for scoping reviews. The inclusion criterion was reported research studies on VS education in the medical curriculum.

RESULTS

A total of 20 studies were included. Three main themes were identified. VS was perceived as an essential part of the general medical student curriculum by VS applicants. Exposure to VS varied considerably, and students generally expressed a need for an increase in VS coverage. The most important positive determinants when choosing VS as a career were having a VS mentor, the technical aspects of VS, and participation in a VS rotation. Frequently cited deterrents were the long training time and demanding lifestyle potentially compromising family life.

CONCLUSIONS

The present scoping review has provided a starting point to better understand the provision of VS education in medical schools across the world. Our review has demonstrated the variability in VS exposure at medical school and described students' sentiments toward VS. We have highlighted the need to determine whether the current curricula are adequate from the perspective of multiple stakeholders (eg, vascular surgeons, educators, general practitioners, a variety of specialists) with a crucial role in the treatment of patients with vascular conditions.

Knowledge of peripheral artery disease: What do the public, healthcare practitioners, and trainees know?

This systematic review evaluated the knowledge and awareness of peripheral artery disease (PAD) within the general public (including patients with peripheral vascular disease), nonspecialist healthcare professionals (nsHCP), and trainees (medical students and trainee doctors). Relevant articles were identified from electronic databases using key search terms: ‘peripheral artery disease’; ‘limb ischaemia’; ‘intermittent claudication’; ‘knowledge’; ‘understanding’; ‘public’; ‘medical professional’. The heterogeneous results were described narratively. A lack of knowledge and understanding of PAD (disease awareness) were identified in all groups. Among nsHCPs, factors which affect knowledge include the level of training, early clinical exposure and the presence of family members with cardiovascular/vascular disease. Within the general public, knowledge and awareness was improved if a family member/friend had a diagnosis, or following a patient-centred consultation with any HCP. Public campaigns are proven effective in improving disease knowledge/awareness in conditions such as stroke alongside sustained patient education. These may provide future avenues to improve PAD knowledge and awareness, in order to effectively manage risk factors and minimise delayed or missed diagnosis of PAD.

Tips and tricks for facilitating teaching of Doppler waveforms and ankle-brachial index in undergraduate level: A practical guide

Although the measurement of ankle-brachial index (ABI) is considered a fundamental skill in assessment and diagnosis of peripheral arterial disease and a predictive tool for cardiovascular events, real-world practice shows that the experience of many health professionals is far from ideal. Not only teaching and practice of ABI measurement in undergraduate medical curricula are limited but various mistakes in the process of calculation, estimation, and interpretation of ABI results in the postgraduate practice have also been documented. Because vascular surgery is a core subject in our medical school, we deal with the difficulties and challenges that undergraduate medical students and nurses face to measure and comprehend ABI. We came up with useful tips and maneuvers to overcome these difficulties. Accordingly, this article provides twelve easy-to-follow useful tips to enhance and facilitate the teaching and comprehension of ABI. Moreover, it favors the simultaneous teaching of Doppler arterial waveform examination as a means to facilitate accurate interpretation and validation of ABI results.

Training to Measure Ankle–Brachial Index at the Undergraduate Level

We examined the effectiveness of teaching ankle–brachial index (ABI) measurement to medical students. ABI was estimated in 28 lower limbs by an experienced vascular surgeon. After a 2-week training course, 5 fourth-year students repeated the estimations and their results were compared with that of the trainer’s. There was no difference in ABI values between trainees and trainer for subjects with mild-to-moderate peripheral arterial disease (PAD; 0.77 ± 0.22 vs 0.77 ± 0.19, respectively, P = .95). In the 4 normal limbs, ABI was 1.37 ± 0.12 and 1.16 ± 0.11, as measured by the trainer and the trainees, respectively ( P < .00001). In subjects with severe PAD, trainees tended to overestimate ABI ( P = .0002) in the beginning of the educational process, but this was no longer the case at a later stage of the training with no difference in ABI values between the 2 examiner groups ( P = .09). In conclusion, training of medical students in ABI measurement can be helpful toward accurate estimation of PAD and merits further practice.
