The Saudi clinical practice guideline for the prophylaxis of venous thromboembolism in long-distance travelers

Methodology for the adolopment of recommendations for the treatment of rheumatoid arthritis in the Kingdom of Saudi Arabia

BACKGROUND

Currently, there are no guidelines for the treatment of rheumatoid arthritis (RA) tailored to the context of the Kingdom of Saudi Arabia (KSA). Adaptation of guidelines accounts for contextual factors and becomes more efficient than de novo guideline development when relevant, good quality, and up-to-date guidelines are available. The objective of this study is to describe the methodology used for the adolopment of the 2021 American College of Rheumatology (ACR) guidelines for the treatment of RA in the KSA.

METHODS

We followed the 'Grading of Recommendations Assessment, Development and Evaluation' (GRADE)-ADOLOPMENT methodology. The adolopment KSA panel included relevant stakeholders and leading contributors to the original guidelines. We developed a list of five adaptation-relevant prioritization criteria that the panelists applied to the original recommendations. We updated the original evidence profiles with newly published studies identified by the panelists. We constructed Evidence to Decision (EtD) tables including contextual information from the KSA setting. We used the PanelVoice function of GRADEPro Guideline Development Tool (GDT) to obtain the panel's judgments on the EtD criteria ahead of the panel meeting. Following the meeting, we used the PANELVIEW instrument to obtain the panel's evaluation of the process.

RESULTS

The KSA panel prioritized five recommendations, for which one evidence profile required updating. Out of five adoloped recommendations, two were modified in terms of direction, and one was modified in terms of certainty of the evidence. Criteria driving the modifications in direction were valuation of outcomes, balance of effects, cost, and acceptability. The mean score on the 7-point scale items of the PANELVIEW instrument had an average of 6.47 (SD = 0.18) across all items.

CONCLUSION

The GRADE-ADOLOPMENT methodology proved to be efficient. The panel assessed the process and outcome positively. Engagement of stakeholders proved to be important for the success of this project.

Travel-Associated Venous Thromboembolism

INTRODUCTION

Long-distance travel is assumed to be a risk factor for venous thromboembolism (VTE). However, the available data have not clearly demonstrated the strength of this relationship, nor have they shown evidence for the role of thromboprophylaxis.

METHODS

We performed a systematic review of the literature. We also summarized available guidelines from 5 groups.

RESULTS

We found 18 studies that addressed this question. Based on the data presented in the review, we conclude that there is an association between VTE and length of travel, but this association is mild to moderate in effect size with odds ratios between 1.1 and 4. A dose-response relationship between VTE and travel time was identified, with a 26% higher risk for every 2 h of air travel (P=0.005) starting after 4 h. The quality of evidence for both travel length and thromboprophylaxis was low. However, low-risk prophylactic measures such as graduated compression stockings were shown to be effective in VTE prevention. There is heterogeneity among the different practice guidelines. The guidelines generally concur that no prophylaxis is necessary in travelers without known thrombosis risk factors and advocate for conservative treatment such as compression stockings over pharmacologic prophylaxis.

CONCLUSIONS

We conclude air travel is a risk factor for VTE and that there is a dose relationship starting at 4 h. For patients with risk factors, graduated compression stockings are effective prophylaxis.

How to write a guideline: a proposal for a manuscript template that supports the creation of trustworthy guidelines

Trustworthy health guidelines should provide recommendations, document the development process, and highlight implementation information. Our objective was to develop a guideline manuscript template to help authors write a complete and useful report. The McMaster Grading of Recommendations Assessment, Development and Evaluation Centre collaborated with the American Society of Hematology (ASH) to develop guidelines for the management of venous thromboembolism. A template for reporting the guidelines was developed based on prior approaches and refined using input from other key stakeholders. The proposed guideline manuscript template includes: (1) title for guideline identification, (2) abstract, including a summary of key recommendations, (3) overview of all recommendations (executive summary), and (4) the main text, providing sufficient detail about the entire process, including objectives, background, and methodological decisions from panel selection and conflict-of-interest management to criteria for updating, as well as supporting information, such as links to online (interactive) tables. The template further allows for tailoring to the specific topic, using examples. Initial experience with the ASH guideline manuscript template was positive, and challenges included drafting descriptions of recommendations involving multiple management pathways, tailoring the template for a specific guideline, and choosing key recommendations to highlight. Feedback from a larger group of guideline authors and users will be needed to evaluate its usefulness and refine. The proposed guideline manuscript template is the first detailed template for transparent and complete reporting of guidelines. Consistent application of the template may simplify the preparation of an evidence-based guideline manuscript and facilitate its use.

Contextual differences considered in the Tunisian ADOLOPMENT of the European guidelines on breast cancer screening

Background

Breast cancer is a common disease in Tunisia and is associated with high mortality rates. The “Instance Nationale de l’Evaluation et de l’Accréditation en Santé” (INEAS) and the Tunisian Society of Oncology decided to develop practice guidelines on the subject. While the development of de novo guidelines on breast cancer screening is a demanding process, guideline adaptation appears more appropriate and context sensitive. The objective of this paper is to describe the adaptation process of the European Guidelines on Breast Cancer Screening and Diagnosis to the Tunisian setting in terms of the methodological process, contextual differences between the source and adoloped guideline, and changes in the recommendations.

Methods

We used the ‘Grading of Recommendations Assessment, Development and Evaluation’ (GRADE)-ADOLOPMENT methodology to prioritize the topic, select the source guideline, and prioritize the questions and the outcomes. Once the source guideline was selected—the European Breast Cancer Guidelines—the European Commission´s Joint Research Centre shared with the project team in Tunisia all relevant documents and files. In parallel, the project team searched for local studies on the disease prevalence, associated outcomes’ baseline risks, patients’ values and preferences, cost, cost-effectiveness, acceptability, and feasibility. Then, the adoloping panel reviewed the GRADE evidence tables and the Evidence to Decision tables and discussed whether their own judgments were consistent with those from the source guideline or not. They based their judgments on the evidence on health effects, the contextual evidence, and their own experiences.

Results

The most relevant contextual differences between the source and adoloped guidelines were related to the perspective, scope, prioritized questions, rating of outcome importance, baseline risks, and indirectness of the evidence. The ADOLOPMENT process resulted in keeping 5 out of 6 recommendations unmodified. One recommendation addressing “screening versus no screening with ultrasound in women with high breast density on mammography screening” was modified from ‘conditional against’ to ‘conditional for either’ due to more favorable ratings by the adoloping panel in terms of equity and feasibility.

Conclusion

This process illustrates both the feasibility of GRADE-ADOLOPMENT approach and the importance of consideration of contextual evidence. It also highlights the value of collaboration with the organization that developed the source guideline.

Assessing the Quality of Clinical Practice Guidelines in the Middle East and North Africa (MENA) Region: A Systematic Review

AIM

Clinical practice guidelines (CPGs) have progressively become a popular tool for making optimal clinical decisions. The literature shows that the poor quality of CPGs can form a barrier against adhering to them, resulting in a suboptimal level of healthcare. The objective of this systematic review is to evaluate the quality of CPGs in the Middle East and North Africa (MENA) region using the Appraisal of Guidelines for Research & Evaluation II (AGREE II) Instrument.

METHODS

The authors searched in the MEDLINE and EMBASE databases through the Ovid interface on May 25, 2019. Keywords relating to CPGs and MENA countries were combined using Boolean search operators. The search was not limited to specific diseases. The quality of guidelines was appraised by two reviewers independently using the AGREE II Instrument. Discrepancies within a group were resolved through the involvement of a principle investigator.

RESULTS

A total of 61 CPGs were appraised. These guidelines were mainly from Saudi Arabia, and the most covered disease topic was cancer. Among the six domains of the AGREE II Instrument, CPGs scored the highest on clarity of presentation (mean 82%), while the lowest score was granted to the rigor of development domain (mean 28%). This indicates substantial deficiencies in reporting the developmental processes of CPGs and the resources used for the synthesis of evidence.

CONCLUSION

From this review, it was found that the number of retrieved guidelines published in the MENA region is limited considering the large geographical area of the MENA region. The main domains that have higher quality scores were clarity of presentation and scope and purpose, whereas domains with the lowest scores were rigor of development and applicability. The authors' findings will help policymakers identify areas for improvement in CPGs, which can lead them to implement strategies such as the training of individuals and recruitment of international experts to ultimately develop high-quality CPGs.

Annotation: travel and thrombosis

Travel appears to be a weak risk factor for venous thromboembolism (VTE) and is more relevant for passengers with additional VTE risk factors. The association is not limited to air travel and is related to duration of travel. Life-threatening pulmonary embolism (PE) is rare. There is limited evidence to support interventions, including 'sensible measures', graduated compression stockings (GCS) and low-molecular-weight heparin (LMWH). It is difficult to confidently define a population who would benefit from thromboprophylaxis and no validated risk assessment exists for this purpose. LMWH has traditionally been used for flight thromboprophylaxis but a direct oral anticoagulant (DOAC) would be a more appealing oral option.

Clinical practice guidelines for surgical antimicrobial prophylaxis: Qualitative appraisals and synthesis of recommendations

RATIONALE, GOALS, AND OBJECTIVES

Clinical practice guidelines (CPGs) for preoperative care have been developed for surgical antimicrobial prophylaxis (SAP). The objective of this study was to synthetize recommendations for SAP based on best-evaluated CPGs.

METHODS

A systematic literature search for documents related to SAP, published between January 2011 and December 2016, was conducted on MEDLINE (PubMed), EMBASE, and specific CPG websites. Three reviewers independently assessed the rigour of development and editorial independence of CPGs based on domains 3 and 6 of the Appraisal of Guidelines for Research & Evaluation II (AGREE II) instrument. CPGs with domain 3 scores of 50% and greater were selected for synthesis of recommendations. Two reviewers independently extracted CPG recommendations from among these documents. A third reviewer performed the synthesis of recommendations.

RESULTS

The search retrieved 363 documents, of which 29 CPGs were appraised using AGREE II. Only eight (28%) scored 50% and greater in domain 3. Most CPGs addressed topics related to preoperative care, including SAP. No conflicting recommendations were found, and most recommendations were based on clinical practice. The only recommendation for which there was a difference among CPGs was with respect to the time to initiate the administration of antibiotics (1 hour before or close to the time of the surgical incision). Four CPGs provide recommendations that demonstrate concern about inadequate SAP prolongation.

CONCLUSION

Several CPGs for SAP were developed without the desired methodological rigour or transparency. Synthesis of recommendations for best-evaluated CPGs provides a broad approach owing to the complementarity of the recommendations.

Venous thromboembolism prophylaxis on flights

Civil aviation has seen a steady increase in the number of scheduled flights over the last ten years and, as a result, more passengers are traveling by air. This has been associated with an increase in flight-related diseases, especially on long-haul flights. One of the most feared complications during flights is venous thromboembolism (VTE), but its true incidence is difficult to measure because of a lack of consensus on elements such as the definition of how long after landing a VTE can be considered to be related to a flight and even how long a flight must last to be considered of long duration. There has been much discussion of the pathophysiological mechanisms of flight-related VTE, of which passengers are at greatest risk, and of what prophylactic measures can be adopted safely and effectively. The purpose of this review is to clarify these points and describe current consensual conduct.
