The utility of elective flexible bronchoscopy to improve quality of life and clinical outcomes for children: A systematic review.

INTRODUCTION: Elective flexible bronchoscopy (FB) is now widely available and standard practice for a variety of indications in children with respiratory conditions. However, there is limited evidence regarding the utility of elective FB in children. This systematic review (SRs) aimed to determine the utility of FB on its impact in clinical decision making and quality of life (QoL). METHODS: We searched Pubmed, Cochrane central register of controlled trials, Embase, World Health Organization Clinical Trials Registry Platform and Cochrane database of SRs from inception to April 20, 2023. We included SRs and randomized controlled trials (RCTs) that used parallel group design (comparing use of elective FB vs. no FB, or a wait-list approach [early FB vs. usual wait FB]) in children aged ≤ 18 years. Our protocol was prospectively registered and used Cochrane methodology for systemic reviews of interventions. RESULTS: Our search identified 859 articles; 102 duplicates were removed, and 753 articles were excluded by title and abstract. Four full text articles were reviewed and subsequently excluded, as none met the inclusion criteria outlined in our patient, intervention, comparator, outcome measures framework. CONCLUSIONS: There is a paucity of high-quality RCT evidence to support the routine use of elective FB in children with respiratory conditions. However, available retrospective and a single prospective study demonstrate the high utility of FB in the elective pediatric setting. REGISTRATION: PROSPERO CRD42021291305.

Cost-Effectiveness of Interventions for Musculoskeletal Foot and Ankle Conditions: A Systematic Review.

OBJECTIVE: Musculoskeletal conditions of the foot and ankle are common, yet the cost-effectiveness of the variety of treatments available is not well defined. The aim of this systematic review was therefore to identify, appraise, and synthesize the literature pertaining to the cost-effectiveness of interventions for musculoskeletal foot and ankle conditions. METHODS: Electronic databases were searched for studies presenting economic evaluations of nonsurgical and surgical treatments for acute or chronic musculoskeletal conditions of the foot and ankle. Data on cost, incremental cost-effectiveness, and quality-adjusted life years for each intervention and comparison were extracted. Risk of bias was assessed using the Drummond checklist for economic studies (range 0-35). RESULTS: Thirty-six studies were identified reporting nonsurgical interventions (n = 10), nonsurgical versus surgical interventions (n = 14), and surgical interventions (n = 12). The most common conditions were osteoarthritis, ankle fracture, and Achilles tendon rupture. The strongest economic evaluations were for interventions managing end-stage ankle osteoarthritis, ankle sprain, ankle fracture, calcaneal fracture, and Achilles tendon rupture. Total ankle replacement and ankle arthrodesis for end-stage ankle osteoarthritis, in particular, have been demonstrated through high-quality studies to be cost-effective compared to the nonsurgical alternative. CONCLUSION: Selected interventions for musculoskeletal foot and ankle conditions dominate comparators, whereas others require thoughtful consideration as they provide better clinical improvements, but at an increased cost. Researchers should consider measuring and reporting costs alongside clinical outcome to provide context when determining the appropriateness of interventions for other foot and ankle symptoms to best inform future clinical practice guidelines.

Impact of vision disorders and vision impairment on motor vehicle crash risk and on-road driving performance: A systematic review.

Vision is important for safe driving, but there is limited understanding regarding the impact of vision disorders on driving ability and safety. This systematic review evaluated and summarized evidence on the impact of vision disorders and impairment on motor vehicle crash (MVC) risk and on-road driving performance across seven databases, was prospectively registered with PROSPERO (CRD42020180135), and study quality rated using a standard tool. Forty-eight studies met the inclusion criteria for MVC risk (N = 36), on-road performance (N = 9), and both MVC risk and on-road performance (N = 3). Of these studies, less than half were rated as 'good' quality. Due to the small number of studies and often conflicting findings, it was not possible to draw firm conclusions for most vision disorders. However, evidence from several 'good' and 'fair' quality studies suggested increased MVC risk with binocular visual field impairment. There was mixed evidence regarding the impact of cataract, glaucoma, age-related macular degeneration and homonymous field loss on MVC risk and no evidence of increased MVC risk with mild VA impairment. This review highlights the need for well-designed future studies to further explore the impact of vision disorders and impairment on driving outcomes to inform evidence-based policy and fitness to drive guidelines.

Improving the translation of search strategies using the Polyglot Search Translator: a randomized controlled trial.

BACKGROUND: Searching for studies to include in a systematic review (SR) is a time- and labor-intensive process with searches of multiple databases recommended. To reduce the time spent translating search strings across databases, a tool called the Polyglot Search Translator (PST) was developed. The authors evaluated whether using the PST as a search translation aid reduces the time required to translate search strings without increasing errors. METHODS: In a randomized trial, twenty participants were randomly allocated ten database search strings and then randomly assigned to translate five with the assistance of the PST (PST-A method) and five without the assistance of the PST (manual method). We compared the time taken to translate search strings, the number of errors made, and how close the number of references retrieved by a translated search was to the number retrieved by a reference standard translation. RESULTS: Sixteen participants performed 174 translations using the PST-A method and 192 translations using the manual method. The mean time taken to translate a search string with the PST-A method was 31 minutes versus 45 minutes by the manual method (mean difference: 14 minutes). The mean number of errors made per translation by the PST-A method was 8.6 versus 14.6 by the manual method. Large variation in the number of references retrieved makes results for this outcome inconclusive, although the number of references retrieved by the PST-A method was closer to the reference standard translation than the manual method. CONCLUSION: When used to assist with translating search strings across databases, the PST can increase the speed of translation without increasing errors. Errors in search translations can still be a problem, and search specialists should be aware of this.
