Sensitivity and specificity of a low-cost screening protocol for identifying children at risk for language disorders

OBJECTIVES: To compare the diagnostic accuracy of a low-cost screening test for identifying children at risk for language disorders with that of a specific language assessment. METHODS: The study was conducted during a polio vaccination campaign in basic health units in western São Paulo, Brazil. The parents/guardians of 1000 children aged between 0 and 5 years were asked to answer questions of a specific screening test. The instrument consisted of a uniform set of questions about the main milestones in language development (from 0 to 5 years of age) with scaled scores to assess responses. There were no exclusion criteria. After the screening test, the children were referred to a specific language assessment by ABFW, following a determined flow of referrals. The results obtained in the screening were compared to those obtained in the specific language assessment; then, the sensitivity, specificity, accuracy, and positive and negative predictive values were determined for the screening test. Children who failed the screening test also underwent an audiological evaluation. The statistical significance was set at 5%. RESULTS: The majority of the participants were aged between 4 and 5 years (21.82%) and were male (51.6%). The sensitivity and specificity values were 82.5% and 98.93%, respectively. The area under the curve was 0.907 (0.887-0.925), and the screening test showed 96% accuracy. CONCLUSIONS: The screening test showed high diagnostic efficiency in determining the risk of language disorders in children aged between 0 and 5 years.

Efeitos do uso de diferentes tecnologias educacionais na aprendizagem conceitual sobre o sistema miofuncional orofacial / Effects of the use of different educational technologies in conceptual learning of the orofacial myofunctional system

RESUMO Objetivo Comparar três métodos de aprendizagem sobre anatomia e fisiologia do sistema miofuncional orofacial, sendo dois interativos (uso de softwares educacionais) e um tradicional, quanto à aprendizagem conceitual de estudantes de graduação em Fonoaudiologia. Métodos Participaram 36 estudantes do segundo ano, alocados randomicamente em grupos: Grupo 1 (G1) - método interativo com jogo computacional 2D (n=12); Grupo 2 (G2) - método interativo com modelo computacional 3D (n=12); Grupo 3 (G3) - método tradicional (textos e figuras 2D) (n=12). Os métodos de aprendizagem foram aplicados durante estudo complementar, por sete semanas, após aula expositiva. Foi realizada uma avaliação de conhecimento antes da aplicação dos métodos de aprendizagem, imediatamente após e seis meses depois da conclusão, e o desempenho dos grupos, nos três momentos, foi comparado. Os dados foram analisados no software SPSS, versão 21 (nível de significância de 5%). Resultados Predominaram sujeitos do gênero feminino, com média de idade de 22,0 (±4,7) anos (F2,33=60,72, p=0,260). Os resultados indicaram que, no G1, apenas o pré-teste diferiu do pós-teste, enquanto no G2 e no G3 o pré-teste diferiu do pós-teste e do pós-teste tardio. Ao verificar a interação entre o desempenho dos grupos e os momentos de avaliação, observou-se que os resultados do GI foram inferiores aos dos demais grupos (F2,22=722,30 p<0,001). Conclusão O uso de modelo computacional 3D foi comparável ao do método tradicional para a aprendizagem conceitual e retenção de conhecimento, em curto e longo prazo, sendo ambos mais eficazes do que o uso de jogo computacional 2D.

ABSTRACT Purpose Compare three learning methods on Anatomy and Physiology of the Orofacial Myofunctional System (OMS): two interactive methods with educational software and one traditional method, regarding the conceptual learning of Speech-Language and Hearing Sciences (SLHS) undergraduate students. Methods Thirty-six students were randomly divided into three groups: Group 1 (G1) - 2D computer game-based method (n=12); Group 2 (G2) - 3D computational model method (n=12); Group 3 (G3) - traditional method (texts and 2D images) (n=12). The learning methods were applied during a complementary study schedule, for seven weeks, after a lecture. Knowledge assessments were conducted prior to the application of the learning methods, immediately after, and six months after completion; the performance of the groups at the three moments was compared. Data were analyzed in SPSS 21 software (p≤0.005). Results Female individuals were predominant, with mean age of 22.0 (±4.7) years (F2.33=60.72; p=0.260). The results show that only the pre-test differed from the short-term test in the G1, whereas the pre-test differed from the short- and the long-term tests in the G2 and G3. Regarding correlation between the performance of the groups and the moments of evaluation, it was observed that the results for the G1 were inferior (F2.22=722.30; p<0.001). Conclusion The 3D computational model was comparable to the traditional method for short- and long-term conceptual learning and knowledge retention, and both were more effective than the 2D computer game.

Atenção Básica como ordenadora do cuidado ao bebê de risco para alterações do neurodesenvolvimento / Primary Health Care as a guide for assistance to infants at risk of neurodevelopmental disorders

RESUMO Objetivo Caracterizar bebês de risco quanto ao perfil sociodemográfico e de saúde e descrever o acompanhamento de parte destes nas Unidades Básicas de Saúde (UBS), segundo diferentes modelos de gestão. Método Levantamento de dados de prontuários dos bebês de risco nascidos na região Oeste da cidade de São Paulo entre agosto de 2013 e fevereiro de 2014 em duas etapas (1 - caracterização; 2 - acompanhamento do desenvolvimento). Resultados Dos 225 indivíduos incluídos na primeira etapa, 51,1% eram do gênero feminino e 7,11% eram gemelares. Predominaram mães adolescentes (45,2%), pardas (50,56%), com ensino fundamental completo (47,60%) e solteiras (46,09%). A média de consultas pré-natais foi de 7,12. A maioria teve parto vaginal (62,21%) com idade gestacional média de 37,05 semanas. A média do Apgar foi de 7,13 no 1º minuto e 8,80 no 5º minuto. O peso médio ao nascimento foi de 2597,21 g, com 50,22% apresentando peso ≤2500g. Na segunda etapa, descreveu-se e comparou-se o acompanhamento do desenvolvimento de 55 bebês, segundo o modelo de gestão das UBS (28 em UBS/Estratégia Saúde da Família [ESF] e 27 em UBS tradicional). As UBS/ESF apresentaram maior média de consultas (p=0,006). Houve maior intervalo entre consultas nas UBS tradicionais. Da amostra, 56% não apresentaram registros referentes aos marcos de desenvolvimento. As medidas de crescimento foram registradas em maior número nas UBS/ESF. Para ambos, o número de consultas e o intervalo entre estas foram menores que o preconizado pelo Ministério da Saúde. Conclusão Ainda existem lacunas no acompanhamento ao bebê de risco, segundo as diretrizes preconizadas na Rede Cegonha.

ABSTRACT Purpose Characterize infants at risk of neurodevelopmental disorders according to sociodemographic and health profiles and describe their monitoring in Basic Health Units (UBS) under different management models. Methods Data were collected from medical records of infants at risk of neurodevelopmental disorders in the west region of the city of Sao Paulo from August 2013 to February 2014 (phase 1 - characterization; phase 2 - monitoring). Results Of the 225 individuals assessed in the first phase of the study, 51.1% were female and 7.11% were twins. Adolescent (45.2%), brown (50.56%), single (46.09%), complete primary education (47.60%) mothers were predominant. The mean number of prenatal visits was 7.12. Most mothers had vaginal delivery (62.22%) at mean gestational age of 37.05 weeks. Mean Apgar scores at the 1st and 5th minutes were 7.13 and 8.80, respectively. Mean weight at birth was 2597.21g., with 50.22% of newborns weighting ≤2500g. In its second phase, the study describes and compares the follow-up of 55 infants according to the UBS management model: 28 in UBS/"Estratégia Saúde da Família" (UBS/ESF) and 27 in traditional UBS (UBS/T). UBS/ESF presented higher mean of consultations (p=0.006). Longer interval between consultations was observed at UBS/T. No records of development milestones were found in 56% of the sample. Growth measures were better registered at UBS/ESF. In both management models, the number of consultations was smaller and the interval between them was shorter than those recommended by the Brazilian Ministry of Health. Conclusion According to the recommended guidelines of the "Rede Cegonha" public policy, gaps in the monitoring of infants at risk of neurodevelopmental disorders are still observed.

Caracterização dos sistemas de referência e contrarreferência em um serviço de fonoaudiologia de alta complexidade na cidade de São Paulo / Effectiveness of referral and counter-referral systems in a high-complexity Speech, Language and Hearing healthcare service in the city of São Paulo

RESUMO Introdução Conhecer o fluxo de referência e contrarreferência de serviços de saúde de alta complexidade é imprescindível para o aperfeiçoamento da assistência fonoaudiológica. Objetivo Analisar o fluxo de pacientes de um serviço de Fonoaudiologia de alta complexidade no Sistema Único de Saúde (SUS). Métodos Estudo descritivo, realizado em serviço de Fonoaudiologia de hospital de alta complexidade. Foram analisados os dados de 373 usuários submetidos à triagem fonoaudiológica (consulta a prontuários). As variáveis analisadas foram: perfil sociodemográfico e fonoaudiológico; origem dos usuários (referência); tempo entre a referência e a realização da triagem; encaminhamentos após a triagem (contrarreferência); tempo entre a conclusão da triagem e o primeiro atendimento fonoaudiológico no serviço de contrarreferência; grau de satisfação com o atendimento fonoaudiológico de contrarreferência. Resultados Predominaram indivíduos com idades entre 0 e 11 anos e 11 meses, do gênero masculino, residentes na cidade de São Paulo, com ensino fundamental incompleto. A hipótese diagnóstica fonoaudiológica de disfonia foi a mais prevalente. A maioria dos usuários foi referenciada pela atenção terciária. A média de tempo de espera para a triagem foi de 56,6 dias (intervalo predominante de 51 a 60 dias). Pouco mais da metade dos sujeitos foi encaminhada para o nível terciário. O tempo de espera pelo atendimento foi maior no nível secundário. A maioria dos usuários referiu como excelente ou bom o grau de satisfação com o atendimento. Conclusão Observou-se alto grau de resolutividade no serviço analisado (atenção terciária) e necessidade de reorganização dos sistemas de referência e contrarreferência na atenção secundária e primária.

ABSTRACT Introduction For optimum quality in Speech, Language and Hearing (SLH) healthcare, it is essential to be aware of the flow of referrals and counter-referrals for high-complexity health services. Purpose To analyze the flow of patients of a high-complexity SLH service in Brazil's Unified Health System (Sistema Único de Saúde - SUS). Methods Descriptive study, made at a Speech, language and hearing (SLH) service of a high complexity hospital. Participants were 373 users who underwent SLH screening (consultation of health records). The variables analyzed were: social-demographic profile; SLH profile; origin of referral of users; time between referral and screening being carried out; referrals after screening (counter-referral); time between conclusion of screening and first SLH consultation in the counter-referred service; and degree of satisfaction with the SLH consultation of the counter-referral. Results The largest group was the age range zero to 11 years 11 months, male, resident in the city of São Paulo, who had not completed primary education. The most prevalent initial diagnosis in SLH terms was dysphonia. The majority of users were referred to tertiary care. The average waiting time for screening was 56.6 days. Just over half the subjects were referred for tertiary care. The waiting time for care was longest at the secondary level. The majority of users stated their degree of satisfaction with the care to be excellent or good. Conclusion A high degree of resolutiveness was observed in the tertiary care service analyzed; and a need was observed in secondary and primary care for reorganization of the systems of referral and counter-referral.

Association between language and hearing disorders - risk identification

OBJECTIVE: To identify children at risk for hearing and/or language disorders and to investigate the association between these risks by conducting pre-validated hearing and language screenings. METHODS: The study was conducted during a polio vaccination campaign in August of 2013 in basic health units in western São Paulo. Parents of children between 2 and 5 years of age were asked to complete two screening tools: a hearing questionnaire (regarding hearing development) and a language production and comprehension scale (including the major language development milestones). The screening tools were administered by different researchers. We compared the risk of having language disorders among children at risk for hearing loss versus children not at risk, as well as the attributable risk and odds ratios. Chi-squared tests and logistic regression analyses were used. RESULTS: The study included 479 children with a mean age of three and one-half years, of whom 26.9% were identified as at risk for deficits in language production, 8.6% were at risk for deficits in language comprehension and 14% were at risk for hearing disorders. The children at risk for hearing disorders were twice as likely as those not at risk to exhibit language production and comprehension deficits. CONCLUSION: The results of this study highlight the importance of establishing and adopting low-cost procedures such as screenings to identify children at risk of developing language and/or hearing disorders in early childhood.

Educação mediada por tecnologia em Fonoaudiologia: impacto na motivação para aprendizagem sobre o Sistema Miofuncional Orofacial / Computer-assisted instruction in Speech-Language and Hearing Sciences: impact on motivation for learning about the Orofacial Myofunctional System

RESUMO O objetivo deste estudo foi comparar três métodos de aprendizagem sobre Anatomia e Fisiologia do Sistema Miofuncional Orofacial quanto à motivação para a aprendizagem em Fonoaudiologia. Participaram 36 estudantes do segundo ano de graduação, após assinatura de termo de consentimento livre e esclarecido. Cada estudante foi alocado randomicamente nos grupos: Grupo I (GI) – 12 participantes do Método Interativo 1 (MI1); Grupo II (GII) – 12 participantes do Método Interativo 2 (MI2); Grupo III (GIII) – 12 participantes do Método Tradicional (MT). Os métodos de aprendizagem foram aplicados durante horário de estudo complementar semanal, após aula expositiva de disciplina obrigatória. Concluída a aplicação dos métodos de aprendizagem, foi aplicado o questionário Instructional Materials Motivation Survey para avaliar a motivação. Os dados foram submetidos à análise estatística no software SPSS versão 21. A comparação entre os grupos foi realizada pela ANOVA seguida pelo teste post hoc de Tukey. O nível de significância foi de 5%. Os grupos diferiram em todos os aspectos avaliados e na pontuação total (F2,33=3691,17 p<0,001). O GII teve maior pontuação geral (GI x GII = p=0,015; GI x GIII = p=0,115; GII x GIII = p<0,001). Com relação à atenção (GII x GIII = p=0,001) e à confiança (GII x GIII = p=0,003), o GII teve maior pontuação que o GIII. Não houve diferença quanto à relevância. O GII teve a maior pontuação para satisfação (GI x GII = p=0,023; GII x GIII = p<0,001). Neste estudo, foi observado que o modelo computacional 3D foi mais eficiente para motivar os estudantes durante a aprendizagem.

ABSTRACT This study aimed to compare the learning motivation of three learning methods as means of teaching Anatomy and Physiology of the Orofacial Myofunctional System of second-year Speech-Language and Hearing Sciences undergraduate students. The study was conducted with 36 students that participated after signing an informed consent form. Each student was randomly allocated to the groups: Group I (GI) – 12 participants using Interactive Method 1 (IM1); Group II (GII) – 12 participants using Interactive Method 2 (IM2); and Group III (GIII) – 12 participants using the Traditional Method (TM). The learning methods were applied during weekly complementary study schedule, following the discipline’s lectures. Upon the conclusion of the learning methods application, the Instructional Materials Motivation Survey questionnaire was administered for evaluating the students’ learning motivation. Data were analyzed using SPSS software version 21. Comparisons between groups were performed using ANOVA followed by Tukey post hoc test. The significance level was set at 5%. The groups differed in all evaluated aspects with the total score (F2,33 = 3691.17 p <0.001). The GII had the highest overall score (GI x GII = p = 0.015; GI x GIII = p = 0.115; GII x GIII = p <0.001). On attention (GII x GIII = p = 0.001) and confidence (GII x GIII = p = 0.003), GII had higher scores than GIII. There was no difference between groups on relevance. For satisfaction, GII had the highest score (GI x GII = p = 0.023; GII x GIII = p <0.001). Therefore, summatively, the 3D computer model was more efficient in enhancing students’ learning motivation.
