Translation and Validation of the Boston Technical Performance Score in a Developing Country

Abstract Introduction: The Technical Performance Score (TPS) was developed and subsequently refined at the Boston Children's Hospital. Our objective was to translate and validate its application in a developing country. Methods: The score was translated into the Portuguese language and approved by the TPS authors. Subsequently, we studied 1,030 surgeries from June 2018 to October 2020. TPS could not be assigned in 58 surgeries, and these were excluded. Surgical risk score was evaluated using Risk Adjustment in Congenital Heart Surgery (or RACHS-1). The impact of TPS on outcomes was studied using multivariable linear and logistic regression adjusting for important perioperative covariates. Results: Median age and weight were 2.2 (interquartile range [IQR] = 0.5-13) years and 10.8 (IQR = 5.6-40) kilograms, respectively. In-hospital mortality was 6.58% (n=64), and postoperative complications occurred in 19.7% (n=192) of the cases. TPS was categorized as 1 in 359 cases (37%), 2 in 464 (47.7%), and 3 in 149 (15.3%). Multivariable analysis identified TPS class 3 as a predictor of longer hospital stay (coefficient: 6.6; standard error: 2.2; P=0.003), higher number of complications (odds ratio [OR]: 1.84; 95% confidence interval [CI]: 1.1-3; P=0.01), and higher mortality (OR: 3.2; 95% CI: 1.4-7; P=0.004). Conclusion: TPS translated into the Portuguese language was validated and showed to be able to predict higher mortality, complication rate, and prolonged postoperative hospital stay in a high-volume Latin-American congenital heart surgery program. TPS is generalizable and can be used as an outcome assessment tool in resource diverse settings.

La trazabilidad en el sistema logístico de medicamentos en Cuba y el uso de las tecnologías de auto-identificación / Traceability in the logistics system of medicines in Cuba, use of auto-identification

La trazabilidad es la capacidad para rastrear la historia, aplicación o ubicación de un objeto bajo consideración. En el ámbito farmacéutico, el rastreo y seguimiento de los medicamentos, incluyendo las vacunas y otros medicamentos biológicos, a lo largo de la cadena de suministro constituye un requisito obligatorio establecido por las autoridades sanitarias a nivel internacional, que se exige en mayor o menor magnitud en las reglamentaciones vigentes. En este artículo se analiza el sistema de codificación y clasificación en el sector de la salud y su estado actual en la cadena de suministro de medicamentos de Cuba. Se presenta un procedimiento para la implementación de las tecnologías de auto-identificación e intercambio electrónico de datos, mediante el uso de GS1 en el sistema de codificación y clasificación empleado en el sector de salud, que permita la trazabilidad en toda la cadena de suministro en Cuba(AU)

Traceability is the capability to track the history, application or location of an object under consideration. In the pharmaceutical field, the tracking and monitoring of medicines, including vaccines and other biological medicines, along the supply chain constitutes a mandatory requirement established by the sanitary authorities at an international level, which is demanded to a greater or lesser extent in the regulations in force. This research was carried out involving different links in the drug supply chain in Cuba, ranging from drug suppliers, drug distribution company, to healthcare centers and pharmacies. An analysis is carried out on the current coding and classification system, detecting the ineffectiveness of the identification of the drugs as the main deficiency. A procedure is proposed for the implementation of the auto-identification and electronic data interchange technologies using GS1 in the coding and classification system used in the health sector that allows traceability throughout the supply chain in Cuba(AU)

Adherencia a las recomendaciones de tromboprofilaxis post-cesárea: estudio de corte transversal / Compliance with post-cesarean section thromboprophylaxis recommendations. A cross sectional study in 233 women

Background: Cesarean section increases four times the risk of venous thromboembolism compared to vaginal delivery. The Royal College of Obstetricians and Gynecologists guidelines are used at our service. A written alert was designed to stratify patients at high, intermediate or low risk making a suggestion for thromboprophylaxis. Aim: To assess the compliance with the guidelines and to evaluate the impact of a written alert in the thromboprophylaxis compliance in women subjected to caesarean section. Patients and Methods: Review of medical records of 233 women aged 19 to 32 years, subjected to a caesarean section in a Gynecology Service, between 2016-2017. Results: Compliance with recommendations was observed in 29% of patients (68/233), 86% in the low-risk group, 26% in the intermediate risk group and 100% in the high risk group. In 41/233 (18%) of patients, a written alert was included in the medical record. Compliance with recommendations in the presence of the written alert was 61% (25/41 women) compared to 22% (43/192) in those lacking the alert (p < 0.01). In women whose emergency caesarean section was the only risk factor, the compliance with the recommendation was 8%, compared with 30% among those who had at least one thrombotic risk factor associated with caesarean section (p < 0.01). Conclusions: In this cross-sectional study, we observed a low compliance with thromboprophylaxis guidelines in cesarean women. We observed that the use of a written alert improved the compliance with thromboprophylaxis.

Agreement limits ranged between -7.3 and 6.8 repetitions for both tests. The 5th, 15th, 50th, 85th, and 95th percentiles were estimated using the Least-Mean-Square algorithm. The cut-off points for MC tests were low: < p15; medium: p15-p85; and high: > p85. Conclusion. Moving sideways and jumping sideways showed a high capacity for reproducibility. The proposed percentiles may be useful to assess MC and could be included and adapted as performance indicators in physical education

¿Por qué continuamos transfundiendo dos unidades de sangre a la vez si con una sola podría ser suficiente? / Why do we keep transfusing two units of blood at the same time if just one could be enough? / Por que continuamos a transfundir duas unidades de sangue ao mesmo tempo se apenas uma pode ser o suficiente?

Resumen: La transfusión de sangre ha sido identificada como uno de los procedimientos médicos más sobreutilizados en pacientes hospitalizados. Una estrategia que permitiría reducir la exposición de los pacientes a la sangre es a través de la implementación de una política de transfusión de una sola unidad, en lugar de dos, para pacientes estables, sin hemorragia y con anemia sintomática. La decisión de transfundir sangre es compleja y depende de varios factores, además, los riesgos de la transfusión se deben sopesar contra los beneficios esperados. La transfusión de dos unidades de sangre a la vez ya no se considera una forma de tratamiento "estándar" para pacientes anémicos sin sangrado activo. Existe una gran oportunidad para reducir el uso excesivo de la transfusión y fomentar las transfusiones de una sola unidad.

Summary: Blood transfusion has been identified as one of the most overused medical procedures in hospitalized patients. One strategy that would reduce the exposure of patients to blood is through the implementation of a single-unit regime for stable patients without bleeding and with symptomatic anemia. The decision to transfuse blood is complex and depends on several factors, in addition, the risks of transfusion must be weighed against the expected benefits. Transfusion of two units of blood at the same time is no longer considered a "standard" form of treatment for anemic patients without active bleeding. There is a great opportunity to reduce the overuse of transfusion and encourage single-unit transfusions.

Resumo: A transfusão de sangue foi identificada como um dos procedimentos médicos usados de mais em pacientes hospitalizados. Uma estratégia que reduziria a exposição dos pacientes ao sangue é por meio da implantação de uma política transfusional de unidade única para pacientes estáveis, sem sangramento e com anemia sintomática. A decisão de transfundir sangue é complexa e depende de vários fatores, além disso, os riscos da transfusão devem ser analisados em relação aos benefícios esperados. A transfusão de duas unidades de sangue ao mesmo tempo não é mais considerada uma forma "padrão" de tratamento para pacientes anêmicos sem sangramento ativo. Há uma grande oportunidade de reduzir o uso excessivo de transfusões e incentivar as transfusões de uma única unidade.

Agreement between physical best and fitnessgram criterion-referenced standards for muscular strength and endurance / Concordância entre os critérios physical best e fitnessgram para a força e resistência muscular

ABSTRACT Objective: To verify the agreement between PHYSICAL BEST and FITNESSGRAM health-related criteria for muscle strength and endurance. Methods: This agreement study had a sample of 81 children and adolescents. Participants were submitted to the PHYSICAL BEST (Sit-up and Pull-up) and FITNESSGRAM (Curl-up and Modified Pull-up) test batteries. Additionally, FITNESSGRAM also proposed criteria for Pull-up test. Results of tests were classified in accordance with their respective criteria. Each group had an interval of seven days between the first and second battery of tests. Statistical analysis used the Kappa index (p<0.05). Results: Sit-up and Curl-up tests among the boys agreed in 72.2% (Kappa=0.368; p=0.004) of cases, and for the girls, in 64.4% (Kappa=0.130; p=0.076). Pull-up (PHYSICAL BEST versus FITNESSGRAM) agreed in 83.3% (Kappa=0.599; p<0.001) for boys. The agreement between Pull-up and Modified Pull-up (PHYSICAL BEST versus FITNESSGRAM) for boys was 47.2% (Kappa=0.071; p=0.533), and for girls, 44.5% (Kappa=0.102; p=0.120). The agreement between the Pull-up and Modified Pull-up tests (FITNESSGRAM) for boys was 58.4% (Kappa=0.215; p=0.143), and for girls, 44.5% (Kappa=0.102; p=0.120). Conclusions: For individual analysis over time, as well as for the comparison of passing rates between different populations, caution is advised when using different criterion-referenced standards for strength and endurance, particularly if using different tests.

Geographical origin of chronic Chagas disease patients in Brazil impacts the performance of commercial tests for anti-T. cruzi IgG

BACKGROUND Chagas disease, caused by Trypanosoma cruzi, affects nearly six million people worldwide. Various serological tests have been developed for its diagnosis. OBJECTIVE Examine the performance of a set of commercial immunological assays in relation to the geographical origin of the patient sample comparing four states of Brazil: Amazonas (AM), Mato Grosso do Sul (MS), Minas Gerais (MG) and Piauí (PI). METHODS Seven immunoassays were employed to detect anti-T. cruzi IgG antibodies in 379 patient samples that had been previously diagnosed using the two-step protocol required by the Brazilian Ministry of Health. FINDINGS A significant variation in the percent reactive was calculated for the samples from AM and MS, while the PI and MG showed a significant variation in the percent non-reactive. The average reactivity index was significantly higher for samples from the states of PI and MG states than AM and MS. MAIN CONCLUSIONS All tests presented a satisfactory performance overall. Yet, variations were observed that were associated to the region of origin of the samples. Our analyses suggest that future evaluations of immunoassays should include a sampling of sera from regions where the test will be applied in addition to the available International Biological Reference Standards.

Objective@#To verify the current cut off points of physical activity intensity for adolescents to assess moderate to vigorous physical activity (MVPA) among overweight or obese adolescents.@*Methods@#The total activity counts, heart rate and steps indicators most commonly used to reflect physical activity intensity were adopted, and a total of 15 MVPA cut off points standards for adolescents were included. Ninety four overweight or obese adolescents were tested for walking and running at 3-7 km/h in a free state, while simultaneously wearing MetaMax 3B gas metabolism analyzer, polar belt and actigraph w-GT3x BT triaxial accelerometer to collect energy consumption and activities count, heart rate and steps. Kappa consistency test and paired χ 2 test were used for statistical analysis.@*Results@#Kappa consistency coefficients (0.27-0.53) <0.60 between all cut off points standards and the "gold standard" and the P <0.01, indicating that the consistency is varied and not strong. In the standard diagnosis of each cut points, low sensitivity (49.11-67.59), high specificity (92.50-97.65), high - LR (0.14-0.52, >0.1) and low DOR (8.26-25.19, <30) indicated high rate of misdiagnosis. Low specificity (36.75-69.41), high sensitivity (84.82-96.36) and low + LR (1.52- 9.83 , <10) indicated a high rate of misdiagnosis; AUC of 0.67-0.80 suggested lower diagnostic performance.@*Conclusion@#Existing physical activity intensity cut off points for overweight or obese adolescents were not consistent with MVPA and have low diagnostic capabilities. The following criteria of MVPA for overweight or obese adolescents are supposed.

Normative data for middle-aged Brazilians in the Mattis Dementia Rating Scale / Dados normativos para brasileiros de meia-idade na escala de avaliação de demência de mattis

ABSTRACT. Despite the advances in the diagnosis of dementia, neuropsychological assessment remains an important tool. The Mattis Dementia Rating Scale (DRS) was designed to evaluate people with suspected dementia and allows for the analysis of different cognitive domains. Considering the numerous cases of early-onset dementia, specific reference standards aimed at the middle-aged population are necessary. Objective: To provide normative data for the middle-aged Brazilian population in DRS and to investigate the influence of education level, age, sex, and intelligence quotient (IQ) on the results. Methods: Overall, 120 healthcare professionals and caregivers from a hospital, who were healthy, aged between 45 and 64 years, and had at least four years of formal education, were included in the study. They were equally divided into six groups. In each age group (45-54 and 55-64 years), there were three educational levels: 4-7, 8-11, and 12 or more (12+) years of formal education. The results are presented as mean values, standard deviations, and percentiles. Comparisons between groups were carried out for age, sex, and education level. Age, years of formal education, and IQ were also analyzed as continuous variables by Spearman's correlation. Results: Concerning education level, the comparison between groups showed differences in the results for the total scale and subscales, except for the Construction subscale. No differences were found for age and sex. Correlations observed for years of formal education and IQ were similar. No correlation was found for age. Conclusions: The present study contributes to the evaluation of dementia concerning people younger than 65 years of age and reinforces the importance of education in the interpretation of the scores.

RESUMO. Apesar dos avanços no diagnóstico de demência, a avaliação neuropsicológica continua sendo uma importante ferramenta. A Escala de Avaliação de Demência de Mattis (Mattis Dementia Rating Scale — DRS) foi projetada para avaliar pessoas com suspeita de demência e permite a análise de diferentes domínios cognitivos. Dados os numerosos casos de demência com início precoce, são necessárias normas específicas para a população de meia-idade. Objetivo: Fornecer dados normativos para a população brasileira de meia-idade na escala Mattis e investigar a influência da escolaridade, idade, sexo e quociente de inteligência (QI) nos resultados. Métodos: 120 funcionários e cuidadores saudáveis de um hospital, com idade entre 45 e 64 anos e com pelo menos quatro anos de escolaridade foram incluídos no estudo, os quais foram divididos igualmente em seis grupos.

Não foram identificadas diferenças para idade e sexo. As correlações observadas para anos de estudo e QI foram semelhantes. Nenhuma correlação foi encontrada para idade. Conclusão: O presente estudo contribui para a avaliação da demência em indivíduos com menos de 65 anos e reforça a importância de considerar o nível educacional na interpretação dos escores.

Recomendaciones para la evaluación del tamaño al nacer y del crecimiento posnatal de los recién nacidos prematuros / Recommendations for the assessment of birth size and postnatal growth of preterm newborns

Es innegable la necesidad de contar con curvas estándar de tamaño al nacer y crecimiento para evaluar y contribuir a orientar las acciones en la atención del neonato. Durante muchos años, se utilizaron las referencias de Lejarraga y Fustiñana, que fueron progresivamente reemplazadas por las de Fenton y Kim.Recientemente, el proyecto INTERGROWTH-21st construyó estándares de crecimiento prescriptivo para evaluar el tamaño al nacer desde las 33 semanas de edad gestacional, referencias para evaluar el tamaño al nacer desde las 24 a las 32,6 semanas de edad gestacional y curvas para el seguimiento longitudinal del crecimiento de recién nacidos pretérmino desde las 27 semanas de edad gestacional. Los Comités de Crecimiento y Desarrollo y de Estudios Feto-neonatales de la Sociedad Argentina de Pediatría, en conjunto con la Secretaría de Gobierno de Salud de la Nación, acordaron recomendar el reemplazo de las curvas de Fenton y Kim por las de INTERGROWTH-21st

It is unquestionable the need to have standards of size at birth and growth to evaluate and contribute to guide the actions in the care of the newborn. For many years the references of Lejarraga and Fustiñana were used, progressively replaced by those of Fenton and Kim. However, recently, the INTERGROWTH-21st project has developed prescriptive growth standards to evaluate the size at birth from 33 weeks of gestational age, references from 24 to 32.6 weeks of gestational age, and curves for postnatal growth from 27 weeks of gestational age onward. The Growth and Development and Neonatal Fetal Studies Committees of the Argentine Society of Pediatrics in conjunction with the Secretary of National Government of Health agreed to recommend the replacement of the Fenton and Kim curves with those of INTERGROWTH-21st.

En el segundo momento, a través del muestreo intencional, se incorporaron dos licenciadas en enfermería del Grupo Médico Auditor. Como métodos teóricos se aplicaron: análisis-síntesis; inducción-deducción; enfoque de sistema y la modelación. Como empírico en el primer momento el método Delphi y en el segundo, la verificación en la práctica. Se aplicaron las consideraciones éticas para este tipo de estudio. Resultados: La propuesta quedó conformada por 17 estándares, agrupados en las 4 funciones generales de enfermería. Los estándares, a su vez, agruparon 166 elementos medibles, que permitieron revisar y evaluar el cumplimiento de los estándares. Conclusiones: Los estándares propuestos y elementos medibles, enfocados a la calidad asistencial de enfermería y la seguridad del paciente, permitirán conformar las auditorías concurrentes de enfermería en el contexto hospitalario(AU)

Introduction: Nursing audit based on well-defined standards, focused on the quality of nursing care and on patient safety, allows that deviations be identified effectively. Objective: To propose a group of standards and measurable elements that allow structuring concurrent nursing audits in the hospital setting. Methods: A technological development research was carried out at Hermanos Ameijeiras Hospital, from January 2016 to January 2018. In the first moment of the study, 20 experts participated, selected through criteria. In the second moment, through intentional sampling, two Nursing graduates were incorporated from the Audit Medical Group. The theoretical methods applied were analysis-synthesis, induction-deduction, system approach, and modeling. The empirical method applied in the first moment was the Delphi method and, in the second moment, verification in practice. Ethical considerations were applied for this type of study. Results: The proposal was made up of 17 standards, grouped into the four general functions of nursing. The standards, in turn, grouped 166 measurable elements, which made it possible to review and evaluate compliance with the standards. Conclusions: The proposed standards and measurable elements, focused on nursing care quality and patient safety, will make it possible to shape concurrent nursing audits in the hospital setting(AU)

Obesidade abdominal no ELSA-Brasil: construção de padrão-ouro latente e avaliação da acurácia de indicadores diagnósticos / Abdominal obesity in ELSA-Brasil (Brazils Longitudinal Study of Adult Health): construction of a latent gold standard and evaluation of the accuracy of diagnostic indicators

Resumo Este estudo avaliou a acurácia de indicadores de obesidade abdominal (OA), definindo uma variável latente como padrão-ouro. Foram estudados 12.232 participantes do ELSA-Brasil de 35 a 74 anos. Avaliou-se três indicadores de OA, estratificados por sexo e raça/cor: circunferência da cintura (CC), razão cintura quadril (RCQ) e índice de conicidade (Índice C). Todos os grupos mostraram elevadas prevalências de OA, maiores entre os homens brancos (~70%) e mulheres pretas (~60%). Observou-se alta acurácia da CC para homens, RCQ e índice C entre homens e mulheres para discriminar OA latente. Identificou-se os seguintes pontos de corte para os indicadores de OA entre os homens brancos, pardos e pretos, respectivamente: CC: 89,9; 90,2 e 91,7cm; RCQ: 0,92; 0,92 e 0,90; índice C: 1,24; 1,24 e 1,24. Para as mulheres brancas, pardas e pretas, respectivamente, os pontos de corte identificados foram: CC: 80,4; 82,7 e 85,4cm; RCQ: 0,82; 0,83 e 0,84; índice C: 1,20; 1,22 e 1,19. A CC entre os homens e a RCQ e índice C entre homens e mulheres apresentaram alto poder para discriminar OA latente, sendo o índice C o melhor indicador.

Abstract This study evaluated the accuracy of abdominal obesity (AO) indicators, defining a latent variable as the gold standard. The study included 12,232 participants of the ELSA-Brasil (Brazil's Longitudinal Study of Adult Health), between 35 and 74 years of age. Three AO indicators were evaluated: waist circumference (WC), waist hip ratio (WHR) and conicity index (C index). Analyses were stratified by sex and race/skin color. All groups had a high prevalence of AO, being greater among white men (~70%) and black women (~60%). A high incidence of WC was observed for men, WHR and C index between men and women for discriminating latent AO. The following cutoff points for AO indicators were identified among white, brown and black men, respectively: WC: 89.9cm; 90.2cm and 91.7cm; WHR: 0.92; 0.92 and 0.90; C index: 1.24; 1.24 and 1.24. The cutoff points identified among white, brown and black women were, respectively: WC: 80.4cm, 82.7cm and 85.4cm; WHR: 0.82; 0.83 and 0.84; C index: 1.20; 1.22 and 1.19 The WC among men and the WHR and C index among men and women presented high power to discriminate latent AO, the C index being the best indicator.
