Use of a Flexible Catheter for the Administration of Subcutaneous Insulin in Diabetic Ketoacidosis: A Feasibility Controlled Clinical Trial.

BACKGROUND: Although intravenous insulin administration is the standard of care in diabetic ketoacidosis (DKA), subcutaneous insulin administration could be a suitable alternative in resource-limited settings, but pain caused by hourly insulin applications are limiting factors for using it, especially in children. We aimed to assess whether the use of a flexible subcutaneous catheter improves comfort in patients with DKA compared with the usual hourly injections' treatment. We also compared the evolution of metabolic variables in patients with DKA using both insulin administration systems. METHODS: Randomized feasibility controlled open trial, comparing 2 ways (flexible catheter and steel needle) for the initial insulin administration in children with DKA, who were randomly selected to receive subcutaneous insulin by a flexible catheter or using standard needles. The main outcome was pain, assessed hourly and secondary outcome time to achieve ketoacidosis resolution. RESULTS: Twenty subjects were included (10 by group). There were no differences between groups in baseline lab values (glycemia, urea, sodium, bicarbonate and pH). Pain assessment at first insulin administration was significantly lower in the intervention group (4.5 vs 0 points; P = 0.001). Similar differences between both treatment arms were observed in every pain assessment. There were no differences between groups regarding the time elapsed to achieve ketoacidosis resolution. (11.4±4.3 vs 16±8.4; P = 0.12). No adverse events or DKA complications were observed. CONCLUSIONS: The use of a flexible catheter reduced the pain associated with subcutaneous insulin administration in nonsevere DKA. The flexible subcutaneous catheter could be a safe alternative for the treatment of uncomplicated DKA in resource-limited settings.

The Influence of Chloride for the Interpretation of Plasma Bicarbonate During the Treatment of Diabetic Ketoacidosis.

INTRODUCTION: Hyperchloremic metabolic acidosis can occur in diabetic ketoacidosis (DKA) and may affect the acid-base interpretation during treatment. OBJECTIVES: This study aims to describe the prevalence of hyperchloremia during the treatment of DKA and its effect on the interpretation of bicarbonate value. METHODS: A cross-sectional study, including all cases of DKA in patients aged 1 to 18 years old admitted from 2010 to 2015, was performed. Laboratory tests were performed on admission (baseline), 2 and 6 hours after admission, and when resolution of DKA was achieved. Adjusted bicarbonate value was calculated using regression equations. RESULTS: Seventy-nine DKA episodes were included. The average age was 13.3 ± 3.8 years. Baseline levels were as follows: plasma glucose, 479 ± 133 mg/dL; pH 7.1 ± 0.083; bicarbonate, 9.65 ± 2.9; and anion gap, 23.9 ± 7.5. The time to achieve resolution of DKA was 12.2 ± 4.4 hours, and the decrease in capillary glucose was 25.5 (19.7-38.2) mg/dL per hour. After 6 hours of treatment, the proportion of patients presenting hyperchloremia increased from 23% to 77%. By using adjusted bicarbonate, the percentage of patients achieving resolution of DKA after 6 hours of treatment would have been 35.4% (confidence interval 95%, 28-49), in comparison with 24.1% (confidence interval 95%, 18-37) using observed bicarbonate (P = 0.004). CONCLUSIONS: The hyperchloremia developed during the treatment of DKA could modify the value of measured plasma bicarbonate concentration and unnecessarily prolong the initial phase of treatment.

Aplicación del Examen Clínico Objetivo Estructurado en la residencia de Pediatría de la Ciudad de Buenos Aires / The Use of the Objective Structured Clinical Examination for Paediatric residents in the City of Buenos Aires

Introducción: A pesar de considerarse el estándar de oro para la evaluación de competencias en posgrado, el Examen Clínico Objetivo Estructurado (ECOE) es escasamente aplicado en América Latina. El Gobierno de la Ciudad de Buenos Aires (GCBA) posee un sistema de residencia de Pediatría con cerca de 400 residentes, distribuidos en 13 hospitales, que comparten examen de ingreso y programa de formación. Nuestro objetivo es describir la experiencia de aplicación del ECOE a todos los residentes de Pediatría del GCBA, y comparar el desempeño según el tipo de hospital. Sujetos y método: Estudio descriptivo, incluyendo a todos los residentes de Pediatría del GCBA que finalizaban primer año, pertenecientes a 13 hospitales (2 pediátricos y 11 generales). El ECOE incluyó 10 estaciones. Resultados: Participaron 85 residentes; el 88,2% (IC 95% 79,7-93,5) aprobó la evaluación. No se encontraron diferencias significativas en la proporción de residentes que aprobó la evaluación entre los que provenían de hospitales pediátricos y los de hospitales generales (89,5 vs. 85,7%; OR = 1,4; IC 95% 0,4-5,5; p = 0,8). Conclusiones: En 2015 por primera vez se desarrolló un ECOE como evaluación unificada para todos los residentes de Pediatría del GCBA. La experiencia permitió identificar debilidades de cada evaluado y del sistema, estableciendo estrategias para superarlas.

Introduction: The Objective Structured Clinical Examination (OSCE) is considered the reference standard for competence evaluation, but its use in Latin America is limited. The City of Buenos Aires Government (CBAG) administers a Paediatric residency system that includes 400 residents distributed in 13 hospitals, sharing an admission system and education program. We aim to describe the experience of administering an OSCE for evaluating all the Paediatric residents of the CBAG. Subjects and method: Descriptive study, including all paediatric residents of the CBAG, belonging to 13 hospitals (2 paediatric and 11 general), ending their first year of training. The OSCE included 10 stations. Results: Eighty-five residents participated in the OSCE, and 88.2% (95% CI 79.7-93.5) passed the examination. There were no significant differences in the pass rate between residents from paediatric hospitals and from general hospitals (89.5 vs. 85.7%; OR = 1.4; 95% CI 0.4-5.5; P = .8). Conclusions: In 2015, the OSCE was administered to all paediatric residents of the CBAG for the first time. This experience allowed identifying weaknesses in the education system, in order to develop strategies to overcome them.

[Correlation between results of the residency admission test and of pediatric certification test in Buenos Aires, Argentina]. / Relación entre el desempeño en el examen de ingreso a la residencia y en el de especialización en pediatría en la Ciudad de Buenos Aires.

In the city of Buenos Aires (CABA), pediatric residents enter the residency program after taking a unified admission test. After completion of the program and passing a final test, the Universidad de Buenos Aires (UBA) provides a professional certification. The objective of this study is to determine if the results obtained in the residency admission test (RAT) and those of the professional certification test (PCT) correlated. This is a cross-sectional study, that included all subjects who passed the pediatrics RAT in CABA in 2004-2009, and that attended the pediatric PCT of the UBA. The score for each subject in both tests was obtained and the corresponding correlation was calculated. Results were divided in quintiles, and the proportion of subjects who improved their position in the PCT with respect to the RAT was calculated. Data from 303 subjects was obtained. The RAT showed a median of 45.0 (over 60 maximum) (IC-range: 43.0-48.7), and the PCT showed a median of 6 points (over 10 max.)(IC-range: 6-8). A significative correlation between results in RAT and PCT was observed (r = 0.37, p < 0.001). Based on their position in the RAT, 43.8% of subjects improved their position in the PCT, without differences between residents attending pediatric and general hospitals (45.6 vs. 31.5%; p = 0.1). In the case of pediatric residents, results of the residency admission test correlate with those obtained in the professional certification test.

En la Ciudad de Buenos Aires (CABA) los ingresantes al sistema de residencia en pediatría lo hacen mediante un examen unificado y, al finalizar, rinden su examen de especialización en la Universidad de Buenos Aires (UBA). Existe evidencia de que el desempeño en determinadas evaluaciones podría predecir el rendimiento posterior. El objetivo de este estudio es evaluar si existe relación entre el examen de ingreso a la residencia (EIR) y el de especialización (EE) en pediatría. Se trata de una investigación transversal que incluye todos los sujetos que aprobaron el EIR de pediatría en CABA en 2004-2009 y que rindieron EE de pediatría en la UBA. Se obtuvo el puntaje de cada sujeto en ambos exámenes y se calculó la correlación correspondiente. Las notas fueron divididas en quintiles, calculando la proporción de alumnos que mejoró su ubicación en el segundo examen con respecto al primero. Se obtuvieron datos de 303 participantes. El examen de ingreso (calificación máxima de 60 puntos) mostró una mediana de 45.0 puntos (IIC: 43.0-48.7) y el examen de especialización (calificación máxima de 10 puntos) mostró una mediana de 6 puntos (IIC: 6-8), verificándose una correlación significativa entre la calificación del EIR y la del EE (r = 0.37, p < 0.001). En relación al quintil de referencia, 43.8% de los alumnos mejoró su ubicación en el EE respecto de la obtenida en el EIR, sin que se registraran diferencias entre residentes de hospitales pediátricos y de hospitales generales (45.6 vs. 31.5%; p = 0.1).
