Confiabilidade de instrumentos de avaliação de retração de cintura escapular em uma unidade de cuidados intermediários neonatal / Reliability of the evaluation of shoulder girdle retraction instrument in a neonatal intermediate unit care

OBJETIVO: Avaliar a confiabilidade inter e intraexaminador, na utilização de instrumentos de avaliação da retração de cintura escapular em crianças internadas em uma unidade de cuidados intermediários neonatal. MATERIAL E MÉTODOS: Estudo quantitativo, transversal e observacional, realizado com recém-nascidos e lactentes que necessitaram de internamento em uma unidade de cuidados intermediários neonatal. A coleta de dados ocorreu de outubro de 2019 a fevereiro de 2020. Para avaliação da retração da cintura escapular foi utilizado um protocolo de inspeção biomecânica elaborado pelas pesquisadoras, que possibilitou a realização de medidas (em centímetros) das bordas mediais superiores e inferiores, direita e esquerda, até a coluna vertebral, com a cabeça em rotação para a direita e para a esquerda, e o sinal do cachecol. As avaliações foram realizadas sempre pelos mesmos avaliadores. Para estimar a confiabilidade inter e intraexaminador do protocolo de inspeção biomecânica e sinal do cachecol, foi utilizado o Índice de Kappa e para as medidas do posicionamento das escápulas, o Coeficiente de Correlação Intraclasse. RESULTADOS: O protocolo de inspeção biomecânica dos sinais sugestivos de retração de cintura escapular demostrou concordância leve a moderada interexaminadores, e substancial a quase perfeita intraexaminador. A concordância interexaminadores obtida no sinal do cachecol foi leve a moderada, e quase perfeita intraexaminador. O posicionamento das escápulas apresentou concordância interexaminadores considerada como boa, e concordância excelente intraexaminador. CONCLUSÃO: A avaliação de sinais sugestivos de retração de cintura escapular, em recém-nascidos e lactentes, apresenta baixos índices confiabilidade interexaminadores e altíssima confiabilidade intraexaminador

OBJECTIVE: To evaluate inter and intra-examiner reliability in the use of instruments to assess shoulder girdle retraction in children hospitalized in a neonatal intermediate care unit. METHODS: Quantitative, cross-sectional and observational study carried out with newborns and infants who required hospitalization in a neonatal intermediate care unit. Data collection took place from October 2019 to February 2020. To evaluate shoulder girdle retraction, a biomechanical inspection protocol developed by the researchers was used, which made it possible to measure (in centimeters) from the upper and lower medial edges, right and left, to the spine, with the head in rotation to the right and left, and the scarf sign. The evaluations were always carried out by the same evaluators. To estimate inter and intra-examiner reliability of the biomechanical inspection protocol and scarf signal, the Kappa Index was used and, for measurements of scapular positioning, the Intraclass Correlation Coefficient. RESULTS: The biomechanical inspection protocol for suggestive signs of scapular girdle retraction showed mild to moderate inter-examiner agreement and substantial to almost perfect intra-examiner agreement. The intra-examiner agreement obtained in the scarf sign was mild to moderate and almost perfect intra-examiner. The positioning of the scapulae showed good inter-examiner agreement and excellent intra-examiner agreement. CONCLUSION: The evaluation of suggestive signs of scapular girdle retraction in newborns and infants has low inter-examiner reliability and very high intra-examiner reliability.

Reproducibility of MRI Features of Uterine Leiomyomas: A Study on Interobserver Agreement and Inter-Method Agreement With Surgery.

PURPOSE: To evaluate interobserver agreement in the interpretation of different MRI features of uterine leiomyomas (UL) according to observers' experience, and to assess the inter-method reproducibility (MRI versus surgery) regarding the International Federation of Gynecology and Obstetrics (FIGO) classification. METHODS: Retrospective study including UL patients who underwent MRI and surgical treatment. Four blinded observers (2 vs >10 years of experience) assessed UL regarding dimensions and volume; inner and outer mantles; FIGO classification; vascularization; degeneration; and diffusion-weighted imaging features. Uterine dimensions and volume were calculated. FIGO classification as ascertained by observers was compared to surgical findings. Intraclass correlation coefficient (ICC) estimates were used for interobserver comparison of numerical variables, and kappa statistic for categorical variables. RESULTS: Thirty-five patients (26y-73y) with 61 UL were included in the interobserver analyses, and 31 patients (54 UL) had available data allowing retrospective surgical FIGO classification for assessment of inter-method reproducibility. Both groups of observers had good to excellent agreement in assessing UL (ICC = 0.980-0.994) and uterine volumes (ICC = 0.857-0.914), mantles measurement (ICC = 0.797-0.920), and apparent diffusion coefficient calculation (ICC = 0.787-0.883). There was substantial agreement for both groups regarding FIGO classification (κ = 0.645-0.767). Vascularization, degeneration and restricted diffusion had lower agreement, varying from reasonable to moderate. Inter-method agreement was reasonable (κ = 0.341-0.395). CONCLUSIONS: Interobserver agreement of MRI for UL was higher for quantitative than qualitative features, with a little impact of observers' experience for most features. MRI agreement with surgery was reasonable. Further efforts should be taken to improve interobserver and inter-method reproducibility for MRI in this scenario.

Reproducibility of the AO/ASIF and Gartland classifications for supracondylar fractures of the humerus in children.

OBJECTIVE: To evaluate the reproducibility of the radiographic classifications of Gartland and the Association for Osteosynthesis/Association for the Study of Internal Fixation (AO/ASIF) for supracondylar fractures of the humerus in children. METHODS: On two occasions, 50 radiographs in anteroposterior and lateral views were evaluated by three pediatric orthopedists in accordance with the Gartland and AO/ASIF pediatric classifications. Their responses were subjected to statistical analysis consisting of calculation of the κ coefficient to assess the intra- and interobserver concordance, in both classifications. RESULTS: The strength of the intraobserver concordance was high or near perfect for the three examiners in the two classification systems. The strength of the interobserver concordance was high in the two systems, with κ coefficients of 0.756 for the Gartland classification and 0.766 for the AO/ASIF classification. CONCLUSION: The Gartland and AO/ASIF classification systems showed similar reproducibility and performance. High strength of concordance was seen in the intra- and interobserver analyses.

OBJETIVO: Avaliar a reprodutibilidade das classificações radiográficas de Gartland e Association for Osteosynthesis/Association for the Study of Internal Fixation (AO/ASIF) para fraturas supracondilianas de úmero em crianças. MÉTODOS: Em duas ocasiões foram avaliadas por três cirurgiões ortopedistas pediátricos 50 radiografias nas incidências anteroposteriores e perfil de acordo com as classificações de Gartland e AO/ASIF pediátrica. As respostas foram submetidas à análise estatística pelo cálculo do coeficiente κ para avaliar a concordância intra- e interobservador, em ambas as classificações. RESULTADOS: A força de concordância intraobservador foi grande ou quase perfeita para os três examinadores nos dois sistemas de classificação. A força de concordância interobservador foi grande nos dois sistemas, com coeficiente κ de 0,756 para classificação de Gartland e de 0,766 para classificação AO/ASIF. CONCLUSÃO: Os sistemas de classificação de Gartland e AO/ASIF mostraram reprodutibilidade e desempenho similar. Observou-se grande força de concordância nas análises intra- e interobservador.
