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.

Risk factors associated with amputation-free survival for patients with peripheral arterial disease: a systematic review

AIMS

Peripheral arterial disease (PAD) is associated with morbidity and mortality, comprising a significant percentage of amputations. As it affects the quality of life of patients with PAD, it is an important health issue. Therefore, the risk factors affecting the outcomes of limb salvage after revascularization should be well investigated. The aim of this review is to summarize risk factors of amputation-free survival (AFS) after interventions targeting patients with PAD to develop evidence-based intervention for improving patient outcomes.

METHODS AND RESULTS

A systematic review following PRISMA guidelines was conducted, and the protocol was registered on PROSPERO (CRD42020183076). PubMed, CINAHL, EMBASE, Cochrane Library, and Web of Science were searched for observational studies published between 2008 and 2019. Search terms included 'peripheral arterial disease', 'risk factors', and 'amputation-free survival'. The quality of the studies was evaluated using the Joanna Briggs Institute's Critical Appraisal Tools. Seventeen cohort studies were included in our study, and 16 risk factors were identified. Risk factors exemplifying a significant influence on decreased AFS were divided into three categories: sociodemographic (e.g. older age, male gender, African-American race, low body mass index, high nutritional risk, frailty), disease-related characteristics (e.g. severity of the disease, intervention site), and comorbidities (e.g. cardiovascular disease, kidney disease, diabetes mellitus, chronic obstructive pulmonary disease, dementia, wide pulse pressure).

CONCLUSION

We found that managing modifiable risk factors, as well as addressing high-risk populations, has the potential to improve outcomes of PAD interventions. More high-quality cohort studies are needed to confirm these findings.

A Clinical Tool (CUE-tool) for Health Care Professionals to Assess the Usability and Quality of the Content of Medical Information Websites: Electronic Delphi Study

Background

As patients are increasingly searching for information about their medical condition on the internet, there is a need for health professionals to be able to guide patients toward reliable and suitable information sources on the internet.

Objective

The aim of the study was to develop a clinical tool for health care professionals to assess the usability and quality of the content of websites containing medical information that could be recommended to patients.

Methods

A 3-round modified electronic Delphi (eDelphi) study was conducted with 20 health care professionals.

Results

In round one of the eDelphi study, of the 68 items initially created, 41 items (29 on usability and 12 on content) were rated as important or very important by more than half of the panel and thus selected for further evaluation in round two. In round two, of the 41 items chosen from round 1, 19 were selected (9 on usability and 10 on content) as important or very important by more than half of the panel for further evaluation. As a result of round three, 2 items were combined as a single item, leaving the instrument with 18 items in total (8 on usability and 10 on content). The tool is freely accessible online.

Conclusions

The CUE-tool can be used to (1) evaluate the usability and reliability of the content of websites before recommending them to patients as a good information source; (2) identify websites that do not have reliable content or may be difficult for patients to use; (3) develop quality websites by using the criteria in the CUE-tool; and (4) identify different qualities between different websites.
