Assessment of the quality and content of clinical practice guidelines for post-stroke rehabilitation of aphasia

A Critical Appraisal of the Congress of Neurological Surgeons Evidence-Based Guidelines on the Evaluation and Treatment of Patients With Thoracolumbar Spine Trauma

Background and objective Thoracolumbar spine trauma (TST) is frequently associated with spinal cord injury and other soft tissue and bony injuries. The management of such injuries requires an evidence-based approach. This study used the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument to assess the methodological quality of clinical guidelines for the management of TST published by the Congress of Neurological Surgeons (CNS). Methods All clinical guidelines on TST published by CNS until 2020 were assessed. Five appraisers from three international centers evaluated the quality of eligible clinical guidelines by using AGREE II. Mean AGREE II scores for each domain were determined. In higher-quality domains, the scores for individual items were analyzed. Results A total of 12 guidelines published by CNS on TST were assessed. Mean scores for all six domains were as follows: Scope and Purpose (75.2%), Stakeholder Involvement (45.4%), Rigor of Development (57.0%), Clarity of Presentation (58.7%), Applicability (16.9%), and Editorial Independence (64.1%). The mean score for the overall quality of all CNS guidelines was 52.9% [95% confidence interval (CI): 52.2-53.5%]. The overall agreement among appraisers was excellent [intra-class correlation coefficients (ICCs) for each guideline ranged from 0.903 to 0.963]. Conclusions CNS guidelines for the management of TST demonstrated acceptable quality across most domains; however, the domains of Applicability and Stakeholder Involvement could be further improved in future guideline updates. The assessors concluded that all guidelines could still be recommended for clinical practice with or without modifications.

Clinical practice guidelines for the nutrition of colorectal cancer patients: a systematic review

PURPOSE

The aim of this study is to rigorously assess the methodological quality of published clinical practice guidelines (CPGs) related to nutrition among colorectal cancer patients, to compile consensus recommendations, and to evaluate the quality of the included CPGs.

METHODS

The systematic search covered eight electronic databases, two relevant professional association websites, and six guideline websites from their inception up to January 22, 2023. The methodological quality of the eligible guidelines was evaluated using the Appraisal of Guidelines Research and Evaluation II (AGREE II) instrument, and then, consensus recommendations were synthesized. The scores for each domain were expressed as the mean ± standard deviation (SD). Using the mean score as the benchmark for comparison, they were subsequently ranked from highest to lowest. The included guidelines were then categorized as having "high," "moderate," or "low" quality based on their scores.

RESULTS

The literature search yielded ten guidelines. The findings indicated that the "Clarity of presentation" domain had the highest mean score (65.2 ± 7.7). This demonstrates how the guidelines effectively articulate recommendations. Additionally, the "Scope and purpose" domain achieved a mean score of 60.7 ± 10.9, followed by "Rigor of development" (51.7 ± 15.7), "Editorial independence" (51.1 ± 21), "Stakeholder involvement" (48 ± 16.8), and "Applicability" domains (47.5 ± 17.3). Two CPGs received an overall rating of "high quality" and were recommended; four CPGs received an overall rating of "moderate" and were recommended with modifications; and four CPGs received an overall rating of "low quality" and were not recommended. Furthermore, this study compiled twenty consensus recommendations related to nine distinct clinical issues.

CONCLUSION

This study identified disparities in the methodological quality of the included CPGs, particularly in the "Applicability" domain, thus emphasizing the need for advancement in clinical feasibility and implementation. Notably, there is few guidelines specifically targeting colorectal cancer nutrition. These synthesized findings provided an intuitive, convenient, and comprehensive reference for evaluating nutrition among colorectal cancer patients. When applying these results, users should make careful decisions based on their specific situations.

Intersectional sociodemographic and neurological relationships in the naming ability of persons with post-stroke aphasia

INTRODUCTION

Significant attention has been given to the role of brain function and disruption in determining performance on naming tasks among individuals with aphasia. However, scholarly pursuit of a neurological explanation has overlooked the fundamental cornerstone of individual health-the underlying social, economic, and environmental factors that shape how they live, work, and age, also known as the social determinants of health (SDOH). This study examines the correlation between naming performance and these underlying factors.

METHODS

Individual level data from the 2010 Moss Aphasia Psycholinguistic Project Database (MAPPD) was matched with the 2009-2011 Medical Expenditure Panel Survey (MEPS) using a propensity score algorithm based on functional, health, and demographic characteristics. Multilevel, generalized, nonlinear regression models were applied to the resulting data set to assess the correlation between the Boston Naming Test (BNT) percentile score and age, income, sex, race, household size, marital status, aphasia type, and region of residence. Poisson regression models with bootstrapped standard errors were used to estimate these relationships RESULTS: Discrete dependent variable estimation with non-normal prior specification included individual level (age, marital status, years of education), socioeconomic (family income), health (aphasia type), household (family size), and environmental (region of residence) characteristics. Regression results indicated that, relative to individuals with Wernicke's, individuals with Anomic (0.74, SE = 0.0008) and Conduction (0.42, SE = 0.0009) aphasia performed better on the BNT. While age at the time of testing was not significantly correlated, higher income level (0.15, SE = 0.0003) and larger family size (0.002, SE = 0.002) was associated with higher BNT score percentiles. Finally, Black persons with aphasia (PWA) (-0.0124, SE = 0.0007) had lower average score percentiles when other factors were held constant.

CONCLUSIONS

The findings reported here suggest higher income and larger family size are associated with better outcomes. As expected, aphasia type was significantly associated with naming outcomes. However, poorer performance by Black PWA and individuals with low income suggests that SDOH can play a critical role (positive and negative) in naming impairment in some populations with aphasia.

Head Acupuncture Plus Schuell's Language Rehabilitation for Post-Stroke Aphasia: A Systematic Review and Meta-Analysis of 32 Randomized Controlled Trials

OBJECTIVE

To evaluate the existing randomized controlled trials (RCTs) for evidence of the efficacy and safety of head acupuncture (HA) plus Schuell's language rehabilitation (SLR) in post-stroke aphasia.

METHODS

Seven databases including Embase, PubMed, Cochrane Library, Technology Periodical Database, the China National Knowledge Infrastructure, SinoMed and Wanfang Data Information Site were searched for RCTs published from database inception until November 14, 2021. RCTs that compared HA plus SLR with sham (or blank) control, acupuncture therapy alone, certain language rehabilitation therapy alone or other therapies for post-stroke aphasia were included. Data were extracted and assessed, and the quality of RCTs was evaluated. Fixed-effects model was used, with meta-inflfluence analysis, meta-regression, and regression-based sub-group analyses applied for exploration of heterogeneity. Publication bias was estimated by funnel plots and Egger's tests.

RESULTS

A total of 32 RCTs with 1,968 patients were included and 51 comparisons were conducted classified as types of strokes and aphasia. (1) For patients with aphasia after ischemic stroke, HA plus PSA showed significantly higher accumulative markedly effective rate [relative risk (RR)=1.55, 95% confidence interval (CI): 1.19-2.02, I²=0%] and accumulative effective rate (RR=1.22, 95% CI: 1.09-1.36, I²=0%). (2) For patients with comprehensive types of stroke, HA plus PSA was more effective in increasing recovery rate (RR=1.89, 95% CI: 1.39-2.56, I²=0%), accumulative markedly effective rate (RR=1.53, 95% CI: 1.36-1.72, I²=9%) and accumulative effective rate (RR=1.14, 95% CI: 1.09-1.19, I²=34%). (3) For patients with aphasia after stroke, HA plus PSA was superior to PSA alone with statistical significance in increasing recovery rate (RR=2.08, 95% CI: 1.24-3.46, I²=0%), accumulative markedly effective rate (RR=1.49, 95% CI: 1.24-1.78, I²=0%) and accumulative effective rate (RR=1.15, 95% CI: 1.06-1.24, I²=39%). (4) For patients with multiple types of aphasia, HA plus PSA also demonstrated significantly higher recovery rate (RR=1.86, 95% CI: 1.28-2.72, I²=0%), accumulative markedly effective rate (RR=1.55, 95% CI: 1.35-1.78, I²=22%), and accumulative effective rate (RR=1.17, 95% CI: 1.11-1.23, I²=41%). (5) For patients with motor aphasia after ischemic stroke, compared with PSA alone, HA plus PSA showed significantly higher accumulative markedly effective rate (RR=1.38, 95% CI: 1.06-1.79, I²=0%) and accumulative effective rate (RR=1.20, 95% CI: 1.05-1.37, I²=0%). Meta-regression analyses were performed without significant difference, and publication bias was found in some comparisons.

CONCLUSION

HA plus SLR was significantly associated with better language ability and higher effective rate for patients with post-stroke aphasia, and HA should be operated cautiously especially during acupuncture at eye and neck. (Registration No. CRD42020154475).

What Determines the Quality of Rehabilitation Clinical Practice Guidelines?: An Overview Study

OBJECTIVE

The aim of the study was to determine what factors determine the quality of rehabilitation clinical practice guidelines.

DESIGN

Six databases were searched for articles that had applied the Appraisal of Guidelines for Research & Evaluation II quality assessment tool to rehabilitation clinical practice guidelines. The 573 deduplicated abstracts were independently screened by two authors, resulting in 81 articles, the full texts of which were independently screened by two authors for Appraisal of Guidelines for Research & Evaluation II application to rehabilitation clinical practice guidelines, resulting in a final selection of 40 reviews appraising 504 clinical practice guidelines. Data were extracted from these by one author and checked by a second. Data on each clinical practice guideline included the six Appraisal of Guidelines for Research & Evaluation II domain scores, as well as the two Appraisal of Guidelines for Research & Evaluation II global evaluations.

RESULTS

All six Appraisal of Guidelines for Research & Evaluation II domain scores were statistically significant predictors of overall clinical practice guideline quality rating; D3 (rigor of development) was the strongest and D1 (scope and purpose) the weakest (overall model P < 0.001, R2 = 0.53). Five of the six domain scores were significant predictors of the clinical practice guideline use recommendation, with D3 the strongest predictor and D5 (applicability) the weakest (overall model P < 0.001, pseudo R2 = 0.53).

CONCLUSIONS

Quality of rehabilitation clinical practice guidelines may be improved by addressing key domains such as rigor of development.

Robotic-assisted gait rehabilitation following stroke: a systematic review of current guidelines and practical clinical recommendations

INTRODUCTION

Stroke is the third leading cause of adult disability worldwide, and lower extremity motor impairment is one of the major determinants of long-term disability. Although robotic therapy is becoming more and more utilized in research protocols for lower limb stroke rehabilitation, the gap between research evidence and its use in clinical practice is still significant. The aim of this study was to determine the scope, quality, and consistency of guidelines for robotic lower limb rehabilitation after stroke, in order to provide clinical recommendations.

EVIDENCE ACQUISITION

We systematically reviewed stroke rehabilitation guideline recommendations between January 1, 2010 and October 31, 2020. We explored electronic databases (N.=4), guideline repositories and professional rehabilitation networks (N.=12). Two independent reviewers used the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument, and brief syntheses were used to evaluate and compare the different recommendations, considering only the most recent version.

EVIDENCE SYNTHESIS

From the 1219 papers screened, ten eligible guidelines were identified from seven different regions/countries. Four of the included guidelines focused on stroke management, the other six on stroke rehabilitation. Robotic rehabilitation is generally recommended to improve lower limb motor function, including gait and strength. Unfortunately, there is still no consensus about the timing, frequency, training session duration and the exact characteristics of subjects who could benefit from robotics.

CONCLUSIONS

Our systematic review shows that the introduction of robotic rehabilitation in standard treatment protocols seems to be the future of stroke rehabilitation. However, robot assisted gait training (RAGT) for stroke needs to be improved with new solutions and in clinical practice guidelines, especially in terms of applicability.

German Language Adaptation of the NAVS (NAVS-G) and of the NAT (NAT-G): Testing Grammar in Aphasia

Grammar provides the framework for understanding and producing language. In aphasia, an acquired language disorder, grammatical deficits are diversified and widespread. However, the few assessments for testing grammar in the German language do not consider current linguistic, psycholinguistic, and functional imaging data, which have been shown to be crucial for effective treatment. This study developed German language versions of the Northwestern Assessment of Verbs and Sentences (NAVS-G) and the Northwestern Anagram Test (NAT-G) to examine comprehension and production of verbs, controlling for the number and optionality of verb arguments, and sentences with increasing syntactic complexity. The NAVS-G and NAT-G were tested in 27 healthy participants, 15 right hemispheric stroke patients without aphasia, and 15 stroke patients with mild to residual aphasia. Participants without aphasia showed near-perfect performance, with the exception of (object) relative sentences, where accuracy was associated with educational level. In each patient with aphasia, deficits in more than one subtest were observed. The within and between population-groups logistic mixed regression analyses identified significant impairments in processing syntactic complexity at the verb and sentence levels. These findings indicate that the NAVS-G and NAT-G have potential for testing grammatical competence in (German) stroke patients.

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.

Systematic review of guidelines to identify recommendations for upper limb robotic rehabilitation after stroke

INTRODUCTION

Upper limb motor impairment is one of the most frequent stroke consequences. Robot therapy may represent a valid option for upper limb stroke rehabilitation, but there are still gaps between research evidence and their use in clinical practice. The aim of this study was to determine the quality, scope, and consistency of guidelines clinical practice recommendations for upper limb robotic rehabilitation in stroke populations.

EVIDENCE ACQUISITION

We searched for guideline recommendations on stroke published between January 1st, 2010 and January 1st, 2020. Only the most recent guidelines for writing group were selected. Electronic databases (N.=4), guideline repertories and professional rehabilitation networks (N.=12) were searched. We systematically reviewed and assessed guidelines containing recommendation statements about upper limb robotic rehabilitation for adults with stroke (PROSPERO registration number: CRD42020173386).

EVIDENCE SYNTHESIS

Four independent reviewers used the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument, and textual syntheses were used to appraise and compare recommendations. From 1324 papers that were screened, eight eligible guidelines were identified from six different regions/countries. Half of the included guidelines focused on stroke management, the other half on stroke rehabilitation. Rehabilitation assisted by robotic devices is generally recommended to improve upper limb motor function and strength. The exact characteristics of patients who could benefit from this treatment as well as the correct timing to use it are not known.

CONCLUSIONS

This systematic review has identified many opportunities to modernize and otherwise improve stroke patients' upper limb robotic therapy. Rehabilitation assisted by robot or electromechanical devices for stroke needs to be improved in clinical practice guidelines in particular in terms of applicability.

Systematic Review of Evidence-Based Guidelines for Prehospital Care

Introduction: Multiple national organizations have identified a need to incorporate more evidence-based medicine in emergency medical services (EMS) through the creation of evidence-based guidelines (EBGs). Tools like the Appraisal of Guidelines for Research and Evaluation (AGREE) II and criteria outlined by the National Academy of Medicine (NAM) have established concrete recommendations for the development of high-quality guidelines. While many guidelines have been created that address topics within EMS medicine, neither the quantity nor quality of prehospital EBGs have been previously reported. Objectives: To perform a systematic review to identify existing EBGs related to prehospital care and evaluate the quality of these guidelines using the AGREE II tool and criteria for clinical guidelines described by the NAM. Methods: We performed a systematic search of the literature in MEDLINE, EMBASE, PubMED, Trip, and guidelines.gov, through September 2018. Guideline topics were categorized based on the 2019 Core Content of EMS Medicine. Two independent reviewers screened titles for relevance and then abstracts for essential guideline features. Included guidelines were appraised with the AGREE II tool across 6 domains by 3 independent reviewers and scores averaged. Two additional reviewers determined if each guideline reported the key elements of clinical practice guidelines recommended by the NAM via consensus. Results: We identified 71 guidelines, of which 89% addressed clinical aspects of EMS medicine. Only 9 guidelines scored >75% across AGREE II domains and most (63%) scored between 50 and 75%. Domain 4 (Clarity of Presentation) had the highest (79.7%) and domain 5 (Applicability) had the lowest average score across EMS guidelines. Only 38% of EMS guidelines included a reporting of all criteria identified by the NAM for clinical practice guidelines, with elements of a systematic review of the literature most commonly missing. Conclusions: EBGs exist addressing a variety of topics in EMS medicine. This systematic review and appraisal of EMS guidelines identified a wide range in the quality of these guidelines and variable reporting of key elements of clinical guidelines. Future guideline developers should consider established methodological and reporting recommendations to improve the quality of EMS guidelines.
