A comparison of skin grafts versus local flaps for facial skin cancer from the patient perspective: protocol for a feasibility study.

BRIEF ABSTRACT: This is a protocol to assess feasibility of conducting a prospective cohort study comparing local flaps versus skin grafts for surgical excision of skin cancer from the face. INTRODUCTION: Skin cancer is the most common malignancy worldwide and the face is one of the most common locations of occurrence. Surgical excision is the most popular treatment for small lesions of the face. Defects can be reconstructed using local flaps or skin grafts. There is a paucity of literature evaluating outcomes after skin cancer surgery from the patient's perspective using valid measurement tools. The purpose of this study is to assess the feasibility of conducting a prospective observational cohort study. The primary outcomes include recruitment rates, eligibility rate, compliance of intervention and rate of completion of the primary outcome (FACE-Q scales) at 3 months. Secondary outcomes include examining patient characteristic and FACE-Q score differences between local flaps to skin grafts and adverse events. METHODS AND ANALYSIS: This study is a prospective cohort study consisting of an anticipated 30 patients aged ≥18 years. The study population will consist of a consecutive sample of non-melanoma facial skin cancer patients undergoing a skin graft or local flap. Patients will be followed and evaluated with the FACE-Q questionnaire at 2 weeks, 3 months, 6 months and 1 year post-operation. The following criteria will determine success: patients who meet eligibility criteria >70%; recruitment rate >70%; compliance with intervention >90%; rate of completion of full-scale prospective study primary outcome (FACE-Q at 3 months) >80%; retention rate at 6-month follow-up visit >70%. DISCUSSION: The findings of this study will be used to guide the sample size calculation for a future, large-scale prospective study.Trial registration: ClinicalTrials.gov (NCT04842279).

Breastfeeding Outcome and Complications in Females With Breast Implants: A Systematic Review and Meta-Analysis.

Breast augmentation is a commonly performed cosmetic procedure. We set out to determine whether there was any effect on breastfeeding in females after breast implants. The aim of this study was to perform a systematic review and meta-analysis of the current evidence on breastfeeding outcome and complications in females with breast augmentation. A systematic review was performed utilizing MEDLINE, EMBASE, and all evidence-based medicine reviews from their respective inception dates to November 7, 2022, to assess outcomes of breastfeeding in females with breast implants (PROSPERO ID: CRD42022357909). This review was in accordance with both the Cochrane Handbook for Systematic Review of Interventions and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eleven studies (4 prospective and 7 retrospective) in total were included in the review. A total of 8197 out of 9965 (82.25%) patients were successfully able to breastfeed after breast implants. Of 5 studies that included a control group, 343,793 of 388,695 (88.45%) women without breast implants successfully breastfed. A meta-analysis of 5 comparative studies showed a significant reduction of breastfeeding in females with breast implants, n = 393,686, pooled odds ratio = 0.45 (95% CI, 0.38 to 0.53). Complications described included pain, mastitis, insufficient or excessive lactation, and nipple inversion. There may be impairment in ability to breastfeed for females who receive breast implants when compared with those without. Additional studies on the topic are needed to further clarify the relationship.

Evaluation of "Spin" in the Abstracts of Systematic Reviews and Meta-analyses of Therapeutic Interventions Published in High-Impact Plastic Surgery Journals: A Systematic Review.

BACKGROUND: "Spin" is a form of reporting bias where there is an misappropriated presentation of study results, often overstating efficacy or understating harms. Abstracts of systematic reviews in other clinical domains have been demonstrated to employ spin, which may lead to clinical recommendations that are not justified by the literature. OBJECTIVES: The objective of this study was to determine the prevalence of spin strategies in abstracts of plastic surgery systematic reviews. METHODS: A literature search was conducted using MEDLINE, Embase, and CENTRAL, to identify all systematic reviews published in the top five plastic surgery journals from 2015-2021. Screening, data extraction, and spin analysis were performed by two independent reviewers. Data checking of the spin analysis was performed by a plastic surgery resident with graduate level training in clinical epidemiology. RESULTS: From an initial search of 826 systematic reviews, 60 systematic reviews and meta-analyses were included in this study. Various types of spin were identified in 73% of systematic review abstracts (n=44). "Conclusion claims the beneficial effect of the experimental treatment despite high risk of bias in primary studies," was the most prevalent type of spin and was identified in 63% of systematic reviews (n=38). There were no significant associations between the presence of spin and study characteristics. CONCLUSIONS: The present study found that 73% of abstracts in plastic surgery systematic reviews contain spin. Although systemic reviews represent the highest level of evidence, readers should be aware of types of "spin" when interpreting results and incorporating recommendations into patient care.

Reporting bias in breast reconstruction clinical trials: Which and when clinical trials get published.

BACKGROUND: Reporting bias refers to the phenomenon in which the reporting of research findings is influenced by the nature of the results. Without the totality of evidence, clinical practice may be misguided. The objective of this work was to examine the extent of reporting bias in clinical trials of breast reconstruction surgery. METHODS: We searched and extracted data from all completed breast reconstruction clinical trials published in ClinicalTrials.gov from database inception to August 2020. Investigators sought to identify published full manuscripts of the registered trials. The primary outcome was classified as positive or nonpositive and trials were classified as industry or nonindustry funded. Time to publication in a peer-reviewed journal was computed and compared using time-to-event analysis. Trial characteristics associated with publication were evaluated using logistic regression. RESULTS: A total of 156 clinical trials were identified, of which, 53 trials were published. The median time to publication was 22 months (IQR, 13-35 months). Industry-funded studies were associated with a longer time to publication (HR = 2.4, p = 0.023) and publication in lower-impact journals (OR = 3.7, p = 0.048). Randomized clinical trials were associated with faster times to publication than nonrandomized studies (aHR = 3.2, p = 0.030). Statistical significance and the effect size were not associated with time to publication. CONCLUSIONS: We found no evidence that industry-funded trials were more likely to report a positive primary outcome. However, industry-funded trials were associated with a longer time to publication and publication in lower-impact journals.

The appropriateness and quality of patient-reported outcome measures (PROMs) in plastic surgery randomized controlled trials: A systematic review.

BACKGROUND: Patient-reported outcome measures (PROMs) quantify patient perspectives to measure outcomes that matter to patients. The aim of this study was to assess the reporting of appropriateness and quality of PROM selection in plastic surgery randomized controlled trials (RCTs). METHODS: MEDLINE, Embase, and CENTRAL were searched from January 1, 2000, to June 5, 2022, to identify published RCTs within the plastic surgery literature. Included studies were categorized as follows: 1) a clearly defined patient-reported primary outcome; 2) a primary outcome could be inferred; or 3) no clear or implied primary outcome. The Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) database was consulted to assess the available literature on the PROMs. RESULTS: There were 130 plastic surgery RCTs identified. Of the 43 studies with a clear or inferred primary outcome, the percentage of studies that commented with supporting references on the PROM's appropriateness for the population, disease/condition, and outcome were 20.9% (n = 9/43), 18.6% (n = 8/43), and 27.9% (n = 12/43), respectively. The percentage of studies that commented on the PROM's validity, reliability, and responsiveness with supporting references were 34.9% (n = 15/43), 14.0% (n = 6/43), and 11.7% (n = 5/43), respectively. There were 21 unique PROMs identified; 28.6% (n = 6/21) were available in the COSMIN database. CONCLUSION: The majority of plastic surgery RCTs assessing patient-reported primary outcomes lack transparency surrounding PROM selection and quality. We recommend investigators conducting plastic surgery clinical research report explicitly why they used a particular PROM and support its appropriateness and psychometric properties with supporting references. Finally, they should familiarize themselves with the COSMIN initiative.

The Effects of Tranexamic Acid in Breast Surgery: A Systematic Review and Meta-Analysis.

BACKGROUND: Tranexamic acid (TXA) is used in trauma and surgical settings. Its role in reducing postoperative blood loss in breast surgery remains unclear. The primary objective of this study was to determine the effect of TXA on postoperative blood loss in breast surgery. METHODS: Searches of the PubMed, Ovid MEDLINE, Embase, CINAHL, and Cochrane Central Register of Controlled Trials databases were performed from inception to April 3, 2020. Inclusion criteria were any retrospective reviews, prospective cohort studies, and randomized controlled trials that administered TXA (topical or intravenously) in the context of breast surgery. Quality of studies were evaluated using the risk of bias in randomized trials tool and the risk of bias in nonrandomized studies of interventions tool. Data were pooled, and a meta-analysis was performed. RESULTS: In total, seven studies were included, representing 1226 patients (TXA, 632 patients; control, 622 patients). TXA was administered as follows: topically (20 mL of 25 mg/mL TXA intraoperatively; n =258 patients), intravenously (1 to 3 g perioperatively; n = 743 patients), or both (1 to 3 g daily up to 5 days postoperatively; n = 253 patients). TXA administration reduced hematoma formation in breast surgery (risk ratio, 0.48; 95% CI, 0.32 to 0.73), with no effect on drain output (mean difference, -84.12 mL; 95% CI, -206.53 to 38.29 mL), seroma formation (risk ratio, 0.92; 95% CI, 0.60 to 1.40), or infection rates (risk ratio, 1.01; 95% CI, 0.46 to 2.21). No adverse effects were reported. CONCLUSION: The use of TXA in breast surgery is a safe and effective modality with low-level evidence that it reduces hematoma rates without affecting seroma rates, postoperative drain output, or infection rates.

Opioid Consumption After Upper Extremity Surgery: A Systematic Review.

There is currently an overprescription of opioids, which may result in abuse and diversion of narcotics. The aim of this systematic review was to investigate opioid prescription practices and consumption by patients after upper extremity surgery. This review was registered a priori on Open Science Framework (osf.io/6u5ny) and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A search strategy was performed using MEDLINE, Embase, PubMed, and Cochrane Central Register of Controlled Trials databases (from their inception to October 17, 2021). Prospective studies investigating opioid consumption of patients aged 18 years or older undergoing upper extremity surgeries were included. The Risk of Bias in Nonrandomized Studies of Interventions and Risk of Bias 2.0 tools were used for quality assessment. In total, 21 articles met the inclusion criteria, including 7 randomized controlled trials and 14 prospective cohort studies. This represented 4195 patients who underwent upper extremity surgery. Most patients took less than half of the prescribed opioids. The percentage of opioids consumed ranged from 11% to 77%. There was moderate to severe risk of bias among the included studies. This review demonstrated that there is routinely excessive opioid prescription relative to consumption after upper limb surgery. Additional randomized trials are warranted, particularly with standardized reporting of opioid consumption and assessment of patient-reported outcomes.

Outcomes After Flexor Tendon Injuries in the Pediatric Population: A 10-Year Retrospective Review.

Background: Pediatric outcomes after flexor tendon repairs are variable, and evidence in the literature remains scarce. Methods: Repair of pediatric flexor tendon injuries was reviewed over a 10-year period (2005-2015). Data collection consisted of patient demographics, injury characteristics, anesthetic choice, repair technique, rehabilitation protocol, American Society for Surgery of the Hand Total Active Motion (TAM) scores, and complications. Results: There were 109 patients included in our study, with a total of 162 digits injured and 235 flexor tendon injuries. The mean age was 12 ± 4.6 years. The small finger (48 of 162; 30%) and the flexor digitorum profundus tendon (126 of 235) were the most commonly injured. The mechanism of injury was mainly from a knife (46 of 109; 42.2%) in zone II (82 of 159; 52%). Injuries were mostly repaired under general anesthetic (61 of 104; 56%). The Kessler technique was the predominant repair mechanism (111 of 225 repairs; 49%). Most patients (103 of 109; 95%) had excellent or good TAM scores with 5 postoperative ruptures reported. The most common complication was stiffness (17 of 121 complications; 14%), with most patients having no complications ( 74 of 109 patients; 68%). Patients were commonly immobilized (mean 8.4 ± 10.3 weeks) with a splint (93 of 109; 85%). There were 85 patients who followed a postoperative rehabilitation protocol for 12 ± 18 weeks. Patient demographics, time of repair, injury characteristics, anesthetic choice, and rehabilitation protocol were not significantly correlated with TAM scores or complication rates. Conclusions: Pediatric tendon injuries have good outcomes with no predictive factors identified. Surgical repairs performed under local anesthetic have similar outcomes without increased rates of complications, but remain underused in the pediatric population.

Multidisciplinary Practice Variations of Anti-Thrombotic Strategies for Free Tissue Transfers.

Background: Venous thrombosis, the leading cause of free flap failure, may have devastating consequences. Many anti-thrombotic agents and protocols have been described for prophylaxis and treatment of venous thrombosis in free flaps. Methods: National surveys were distributed to microsurgeons (of both Plastics and ENT training) and hematology and thrombosis specialists. Data were collected on routine screening practices, perceived risk factors for flap failure, and pre-, intra-, and post-operative anti-thrombotic strategies. Results: There were 722 surveys distributed with 132 (18%) respondents, consisting of 102 surgeons and 30 hematologists. Sixty-five surgeons and 9 hematologists routinely performed or managed patients with free flaps. The top 3 perceived risk factors for flap failure according to surgeons were medical co-morbidities, past arterial thrombosis, and thrombophilia. Hematologists, however, reported diabetes, smoking, and medical co-morbidities as the most important risk factors. Fifty-four percent of physicians routinely used unfractionated heparin (UFH) or low-molecular-weight heparin (LMWH) as a preoperative agent. Surgeons routinely flushed the flap with heparin (37%), used UFH IV (6%), or both (8%) intra-operatively. Surgeons used a range of post-operative agents such as UFH, LMWH, aspirin, and dextran while hematologists preferred LMWH. There was variation of management strategies if flap thrombosis occurred. Different strategies consisted of changing recipient vessels, UFH IV, flushing the flap, adding post-operative agents, or a combination of strategies. Conclusions: There are diverse practice variations in anti-thrombotic strategies for free tissue transfers and a difference in perceived risk factors for flap failure that may affect patient management.

Contexte: La thrombose veineuse, principale cause de l'échec des volets libres, peut avoir des conséquences catastrophiques. De nombreux agents et protocoles antithrombotiques ont été décrits pour la prévention et le traitement de la thrombose veineuse dans les volets libres. Méthodes: Des enquêtes nationales ont été distribuées à des chirurgiens spécialistes de microchirurgie (ayant à la fois une formation en chirurgie plastique et ORL) et à des spécialistes en hématologie et thrombose. Les données collectées ont porté sur les pratiques usuelles de sélection, les facteurs de risque perçus d'échec des volets, ainsi que sur les stratégies antithrombotiques pré-, per- et postopératoires. Résultats: Sur les 722 enquêtes distribuées, il y a eu 132 répondants (18 %) consistant en 102 chirurgiens et 30 hématologistes. Soixante-cinq chirurgiens et neuf hématologues réalisent ou gèrent régulièrement des patients avec des volets libres. Les trois plus importants facteurs de risque perçus d'échec du volet, selon les chirurgiens, étaient les comorbidités médicales, un antécédent de thrombose artérielle et la thrombophilie. De leur côté, les hématologues ont indiqué que le diabète, le tabagisme et les comorbidités médicales étaient les facteurs de risque les plus importants. Cinquante-quatre pour cent des médecins utilisent régulièrement de l'héparine non fractionnée ou de l'héparine de bas poids moléculaire (HBPM) comme agent préopératoire. Les chirurgiens rincent régulièrement le volet à l'héparine (37 %), utilisent de l'héparine non fractionnée par voie IV (6 %) ou les deux (8 %) en peropératoire. Les chirurgiens utilisent un éventail d'agents postopératoires, tels que l'héparine non fractionnée, l'HBPM, l'aspirine et le dextran tandis que les hématologues préfèrent l'HBPM. Des variations dans les stratégies de gestion ont été observées en cas de survenue d'une thrombose du volet. Différentes stratégies ont consisté à changer les vaisseaux receveurs, administrer de l'héparine non fractionnée IV, rincer le volet, ajouter des agents postopératoires, ou combiner ces stratégies. Conclusions: Il y a différentes variations dans la pratique de stratégies antithrombotiques pour les transferts de tissus libres et une différence dans les facteurs de risque perçus d'échec du volet qui peuvent avoir des répercussions sur la gestion des patients.

Outcomes of Management of Recurrent Dupuytren Contracture: A Systematic Review and Meta-analysis.

BACKGROUND: With numerous treatment modalities available, it is unclear whether the treatment of recurrent Dupuytren disease is as effective as its initial treatment. We aimed to investigate the outcomes of management of recurrent Dupuytren contracture. METHODS: Adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, MEDLINE, Embase, PubMed, CINAHL, and Cochrane Central Register of Controlled Trials were searched from their inception to April 2020. Studies of patients aged above 18 years undergoing treatment for recurrent Dupuytren contractures were included. The Risk Of Bias In Non-randomized Studies-of Interventions tool was used for quality assessment. The study was registered with Open Science Foundation. RESULTS: A systematic review identified 12 studies: 311 patients with 224 affected digits-index (n = 5; 2.2%), long (n = 17; 7.6%), ring (n = 57; 25.4%), small (n = 112; 50%), and unspecified (n = 33; 14.7%); of these, there were 76 metacarpophalangeal joints (MCPJ; 45.5%), 90 proximal phalangeal joints (PIPJ; 53.9%), and 1 distal interphalangeal joint (0.6%). Previous treatment included the following: percutaneous needle aponeurotomy (n = 103 of 311 patients; 33.1%), collagenase clostridium histolyticum-injection (CCH; n = 75 of 311; 24.1%), limited fasciectomy (LF) ± skin graft (n = 83 of 311; 26.7%), fasciotomy (n = 1 of 311; 0.3%), and unspecified (n = 64 of 311; 20.6%). Recurrence was treated by percutaneous needle aponeurotomy (n = 68 of 311 patients; 21.9%); CCH injection (n = 53 of 311; 17.0%); aponeurotomy or dermofasciectomy or LF (n = 176 of 311; 56.6%); ray/digit amputation (n = 8 of 311; 2.6%); and PIPJ arthrodesis (n = 6 of 293; 2.0%). Range of motion was improved by 23.31° (95% confidence interval [CI] = 13.13°-33.50°; I2 = 67%; P = .05) and 15.49° (95% CI = 2.67°-28.31°; I2 = 76%; P = .01) for MCPJ and PIPJ, respectively. CONCLUSIONS: There is low level of evidence that both surgical and nonsurgical treatments provide clinically important improvements for recurrent Dupuytren contracture.

Management and Outcomes of Clinical Scaphoid Fractures in Children.

Background: Acute wrist trauma with clinical suspicion of a scaphoid fracture, but normal radiographs, is known as a clinical scaphoid fracture. Standard treatment involves immobilization and repeat radiographs in 10 to 14 days. When repeat radiographs are normal but a scaphoid fracture is still clinically suspected, the optimal management in children is unknown. This study retrospectively assessed the management and outcomes of pediatric patients diagnosed with clinical scaphoid fractures. Methods: A retrospective study was performed of all patients over a 2-year period treated for a clinical scaphoid fracture at a tertiary pediatric center. Patients were included if they had clinical signs of a scaphoid fracture and 2 negative x-rays 7 to 14 days apart postinjury. Results: Ninety-one patients with a mean age of 13.2 years (range: 7.8-17.7) were included. Sixteen patients (17.6%) underwent computed tomography (CT) or magnetic resonance imaging (MRI) at a mean time of 10.2 weeks postinjury. Five patients (5.5%) were diagnosed with a scaphoid fracture by x-ray or CT at an average of 4.5 weeks postinjury (range: 3-6). Six patients were diagnosed with other wrist fractures at a mean time postinjury of 3.1 (range: 3-6.5) weeks. Out of 195 total radiographs, the surgeon and radiologist disagreed on 59 (30.2%) images. No patients underwent surgery. Conclusions: Management of clinical scaphoid fractures at our institution was relatively uniform: nearly all patients were immobilized and less than 20% received advanced imaging. Our findings suggest a low but non-zero occult scaphoid fracture rate, discordance in radiologic interpretation, and lack of advanced imaging, providing an avenue for future prospective studies.

A Comparison of Conservative and Operative Management of Thumb Ulnar Collateral Ligament Avulsion Fractures in Children.

Background: The optimal management of pediatric thumb ulnar collateral ligament (UCL) avulsion fractures remains poorly defined. The purpose of this study was to elucidate patient outcomes based on initial management and fracture characteristics. Methods: A retrospective study of all patients younger than 18 years of age presenting with a thumb UCL avulsion fracture was performed. Patients were grouped by their initial management. The primary outcome of the study was time to return to full activity. Fractures were characterized by articular surface involvement, displacement, and rotation. Results: Forty-seven patients with thumb UCL avulsion fractures were identified. Ten patients underwent surgery as initial treatment; all healed without complication, with a mean recovery time of 6.2 ± 1.8 weeks. Thirty-seven patients were treated conservatively; although most healed, the recovery time was longer (9.2 ± 8.3 weeks, adjusted hazard ratio = 2.3, 95% confidence interval = 1.0-5.5). Four cases (11%) required conversion to surgery that all healed without complications. Fractures treated with immobilization alone were significantly smaller, less displaced, and less rotated than those initially treated with surgery; however, 19 fractures that would have met criteria for surgery were treated with immobilization and successfully healed within 7.1 ± 2.9 weeks. Fracture characteristics did not predict which patients would fail conservative treatment or have prolonged recovery times. Conclusions: While surgery provided definitive treatment without delay in recovery, immobilization may not be an unreasonable treatment choice even for patients with large or displaced fractures. In cases where patients failed immobilization, surgery as a second-line treatment had good results.

Assessment of the Readability, Adequacy, and Suitability of Online Patient Education Resources for Benign Vascular Tumours Using the DISCERN Instrument.

OBJECTIVE: This study aims to assess the quality and readability of Internet-based patient resources for vascular tumours in order to understand which areas require improvement. METHODS: A World Wide Web search was performed, in addition to a literature review using PubMed, Ovid MEDLINE, and EMBASE. Any material that contained information on vascular tumours pertaining to patient education was included. We evaluated resources with DISCERN and Flesch Reading Ease scores when applicable. The language of publication was restricted to English and French. This review was registered with PROSPERO (CRD42018087885). RESULTS: A total of 117 online resources were screened, with 73 resources included in the final analysis. The overall DISCERN rating for the patient resources was 1.8 (0.8). The majority of online resources failed to depict the entire spectrum of benign vascular tumours. The mean Flesch score was 36 (19), which translates to a college-level readability. CONCLUSION: The majority of resources were not adequate or comprehensive and were written at a much higher level than the average reader would be expected to comprehend.

OBJECTIF: La présente étude vise à évaluer la qualité et la lisibilité de ressources en ligne sur les tumeurs vasculaires pour les patients afin de déterminer les améliorations à apporter. MÉTHODOLOGIE: Les chercheurs ont effectué une recherche dans Internet et procédé à une analyse bibliographique dans PubMed, Ovid MEDLINE et EMBASE. Tous les documents qui contenaient de l'information sur les tumeurs vasculaires à l'intention des patients étaient inclus. Les chercheurs ont évalué les ressources à l'aide des scores de DISCERN et de Flesch Reading Ease, si la situation le justifiait. La langue des publications était restreinte à l'anglais et au français. La présente analyse a été enregistrée dans PROSPERO (CRD42018087885). RÉSULTATS: Au total, les chercheurs ont examiné 117 ressources en ligne, dont 73 ont fait partie de l'analyse définitive. La classification DISCERN globale des ressources pour les patients était de 1,8 (0,8). La majorité des ressources en ligne ne décrivaient pas tout le spectre des tumeurs vasculaires bénignes. Le score de Flesch moyen s'élevait à 36 (19), soit une lisibilité de niveau collégial. CONCLUSION: La majorité des ressources étaient inadéquates ou incomplètes et étaient rédigées à un niveau de lecture beaucoup plus élevé que ce à quoi on pourrait s'attendre chez un lecteur moyen.

Scratch Collapse Test for Carpal Tunnel Syndrome: A Systematic Review and Meta-analysis.

BACKGROUND: Despite the fact that carpal tunnel syndrome (CTS) is the most common entrapment neuropathy, the diagnostic accuracy of clinical screening examinations for CTS is controversial. The scratch collapse test (SCT) is a novel test that may be of diagnostic advantage. The purpose of our study was to determine the diagnostic accuracy of the SCT for CTS. METHODS: A literature search was performed using PubMed (1966 to April 2018); Ovid MEDLINE (1966 to April 2018); EMBASE (1988 to April 2018); and Cochrane Central Register of Controlled Trials (The Cochrane Library, to April 2018). We examined the studies for the pooled sensitivity, specificity, and likelihood ratios of the SCT. This review has been registered with PROSPERO (CRD42018077115). RESULTS: The literature search generated 13 unique articles. Seven articles were included for full text screening and 3 articles met our inclusion criteria, all of which were level II evidence with low risk of bias (165 patients). Pooled sensitivities, specificities, positive likelihood ratio, and negative likelihood ratios were 0.32 [95% CI (0.24-0.41)], 0.62 [95% CI (0.45-0.78)], 0.75 [95% CI (0.33-1.67)], and 1.03 [95% CI (0.61-1.74)], respectively. The calculated area under the summary receiver operating characteristic (AUSROC) curve was 0.25, indicating a low diagnostic accuracy. CONCLUSION: The SCT has poor sensitivity; however, it is moderately specific. Based on the current literature and their variable quality of the evidence, we conclude that the SCT is not an adequate screening test for detecting CTS.
