A Critical Appraisal of the Quality of Vertigo Practice Guidelines Using the AGREE II Tool: A EuroAIM Initiative

OBJECTIVES

The aim of this review is to assess the methodological quality of guidelines for the management of vertigo and dizziness and to compare their recommendations, with specific focus on neuroimaging.

DATABASES REVIEWED

MEDLINE, EMBASE, National Guideline Clearinghouse, and National Institute for Health and Clinical Excellence database.

METHODS

In March 2022, a systematic search was performed to find practice guidelines of management of vertigo and dizziness. The evaluation of guidelines quality was performed independently by four authors using the AGREE II tool. We excluded from the results those guidelines that were not primarily focused on vertigo and dizziness, such as national/international guidelines in which vertigo and dizziness were only briefly mentioned.

RESULTS

Our strategy of literature search identified 161 studies, and 18 guidelines were selected for the appraisal. Only five guidelines reached the acceptance level in the overall result (at least 60%), with three of them reaching the highest scores (at least 80%). The highest scores were found in Domain 6 "Editorial Independence," Domain 1 "Scope and purpose," and Domain 4 "Clarity of presentation" (median value = 66%, 62%, and 61%, respectively). The remaining domains showed a low level of quality: Domain 2 "Stakeholder Involvement," Domain 3 "Rigor of development," and Domain 5 "Applicability" had median values of 27%, 27%, and 22%, respectively. The quality of these guidelines was very low, because of low involvement of multidisciplinary teams in writing guidelines recommendations.

CONCLUSION

Considering all guidelines, only three had a "high" overall score, whereas 13 of 18 (72%) of them were rated as of "low" quality. Future guidelines might take this into account to improve clinical applicability.

Tailored GuideLine Implementation in STrokE Rehabilitation (GLISTER) in Germany. Protocol of a Mixed Methods Study Using the Behavior Change Wheel and the Theoretical Domains Framework

Objective

Evidence-based guidelines are important for informing clinical decision-making and improving patient outcomes. There is inconsistent usage of guidelines among physical therapists involved in stroke rehabilitation, suggesting the existence of a gap between theory and practice. Addressing the German guideline "evidence-based rehabilitation of mobility after stroke (ReMoS)," the aims of this project are (1) to describe the current physical therapy practice within the context of stroke rehabilitation in Germany, (2) to evaluate barriers and facilitators of guideline usage, (3) to develop, and (4) to pilot test a theory-based, tailored implementation intervention for the benefit of guideline recommendations.

Materials and Methods

This study uses a stepwise mixed methods approach for implementing a local guideline. A self-reported online questionnaire will be used to survey the current physical therapy practice in stroke rehabilitation. The same survey and systematic-mixed methods review will be used to evaluate the barriers and facilitators of guideline usage quantitatively. Semi-structured interviews will add a qualitative perspective on factors that influence ReMoS guideline implementation. The Behavior Change Wheel and Theoretical Domains Framework will be used to support the development of a tailored implementation intervention which will be pilot tested in a controlled study. Patient and physical therapy-related outcomes, as well as the appropriateness, such as acceptance and feasibility of the tailored implementation intervention, will be analyzed.

Conclusion

This will be the first endeavor to implement a guideline in German stroke rehabilitation with a focus on changing care provider behavior based on the knowledge of current practice and determining factors using a tailored and theory-based intervention.

Implementing spirometry and fractional exhaled nitric oxide testing in childhood asthma management in UK primary care: an observational study to examine training and implementation cost and impact on patient's health use and outcome

OBJECTIVES

Implementation of guidelines into clinical practice is challenging and complex. This study aims to (1) identify the training needs and capacity requirements, and (2) explore the impact on healthcare utilisation and asthma-related quality of life of implementing both spirometry and fraction of exhaled nitric oxide in diagnosis of asthma among children in the UK primary care.

METHODS

Ten UK general practitioner practices and a total of 612 children (5-16 years) with diagnosed or suspected asthma were invited to participate in this prospective observational study. The total times that the trainer and trainee clinical staff spent on developing the training package, providing and receiving, and performing and interpreting the two tests as part of routine child asthma review were collected, and costs were calculated. We compared healthcare utilisation and asthma-related and general health-related quality of life data between the 6 months before and after the asthma review guided by objective tests.

RESULTS

The average training cost for the 27 primary care clinical members was £1395. The average cost to implement and deliver the test-guided asthma review among the 612 included children was £22. In the 6 months following the tests-guided asthma review, both unplanned primary care attendance, and hospital admissions were reduced, and the asthma-related health status increased significantly.

CONCLUSION

This study provides robust cost estimates of the resources needed to implement the National Institute for Health and Care Excellence asthma guideline. It also demonstrates the potential to save healthcare costs and improve health status among asthmatic children by implementing this guideline.
