ABSTRACT

Abstract Objectives: to describe the prevalence of chronic respiratory diseases and their pharmacological management in children and adolescents in Brazil. Methods: data from the Pesquisa Nacional de Acesso, Uso e Promoção do Uso Racional de Medicamentos no Brasil (PNAUM)(National Access Survey, Use and Promotion of Rational Use of Medicines in Brazil),a population-based cross-sectional study, were analyzed. Household surveys were conducted between September 2013 and February 2014. We included the population under 20 years of age with chronic respiratory diseases. Prevalence of disease, indication of pharmacological treatment, and their use were assessed. Results: the prevalence of chronic respiratory diseases in children aged less than 6 years old was 6.1% (CI95%= 5.0-7.4), 4.7% (CI95%= 3.4-6.4) in those 6-12 years, and 3.9% (CI95%= 2.8-5.4) in children 13 years and older. Children under 6 showed a higher prevalence of pharmacological treatment indication (74.6%; CI95%= 66.0-81.7), as well as medication use (72.6%; CI95%= 62.8-80.7). Of those using inhalers, 56.6% reported using it with a spacer. The most frequent pharmacologic classes reported were short-acting β2 agonists (19.0%), followed by antihistamines (17.2%). Conclusion: children and adolescents who report chronic respiratory diseases living in urban areas in Brazil seem to be undertreated for their chronic conditions. Pharmacological treatment, even if indicated, was not used, an important finding for decision-making in this population.


Resumo Objetivos: descrever a prevalência de doenças respiratórias crônicas e seu manejo farmacológico em crianças e adolescentes no Brasil. Métodos: foram analisados os dados da Pesquisa Nacional de Acesso, Uso e Promoção do Uso Racional de Medicamentos no Brasil (PNAUM), um estudo transversal de base populacional. As pesquisas domiciliares foram realizadas entre setembro de 2013 e fevereiro de 2014. Incluímos a população com menos de 20 anos de idade com doenças respiratórias crônicas. Foi avaliada a prevalência de doença, indicação de tratamento farmacológico e seu uso. Resultados: a prevalência de doenças respiratórias crônicas em menores de 6 anos foi de 6,1% (IC95%= 5,0-7,4), 4,7% (IC95%= 3,4-6,4) naqueles 6-12 anos e 3,9% (IC95%= 2,8-5,4) em crianças com 13 anos ou mais. Crianças menores de 6 anos apresentaram uma maior prevalência de indicação de tratamento farmacológico (74,6%; IC95%= 66,0-81,7), assim como uso de medicamentos (72,6%; IC95%= 62,8-80,7). Dos usuários de inaladores, 56,6% relataram o uso com espaçador. As classes farmacológicas mais frequentemente relatadas foram β2 agonistas de curta ação (19,0%), seguidos por anti-histamínicos (17,2%). Conclusão: crianças e adolescentes que relatam doenças respiratórias crônicas residentes em áreas urbanas no Brasil parecem ser subtratados para suas condições crônicas. O tratamento farmacológico, mesmo quando indicado, não foi utilizado em sua totalidade, um achado importante para a tomada de decisão nessa população.

ABSTRACT

ABSTRACT Objective To investigate whether different genotypes of p.Arg16Gly, p.Gln27Glu, p.Arg19Cys and p.Thr164Ile variants interfere in response to treatment in children and adolescents with moderate to severe acute asthma. Methods This sample comprised patients aged 2 to 17 years with a history of at least two wheezing episodes and current moderate to severe asthma exacerbation. All patients received multiple doses of albuterol and ipratropium bromide delivered via pressurized metered-dose inhaler with holding chamber and systemic corticosteroids. Hospital admission was defined as the primary outcome. Secondary outcomes were changes in forced expiratory volume in the first second after 1 hour of treatment, and for outpatients, length of stay in the emergency room. Variants were genotyped by sequencing. Results A total of 60 patients were evaluated. Hospital admission rates were significantly higher in carriers of the genotype AA relative to those with genotype AG or GG, within the p.Arg16Gly variant (p=0.03, test χ2, alpha=0.05). Secondary outcomes did not differ between genotypes. Conclusion Hospital admission rates were significantly higher among carriers of the genotype AA within the p.Arg16Gly variant. Trial registration: ClinicalTrials.gov: NCT01323010

ABSTRACT

Introducción. El asma es una enfermedad inflamatoria crónica con alta prevalencia en pacientes pediátricos. Existen resultados contradictorios respecto al efecto de esta enfermedad en los índices de caries dental. El objetivo del estudio fue determinar la prevalencia de caries dental en pacientes pediátricos asmáticos con medicación inhalatoria. Población y métodos. Estudio de casos y controles cuya muestra estuvo conformada por pacientes pediátricos que acudieron al Centro Médico Naval "Cirujano Mayor Santiago Távara" de diciembre de 2014 a marzo de 2015. Se dividieron en dos grupos: el primero (casos), integrado por pacientes asmáticos que utilizaban inhaladores en su tratamiento; el segundo (controles), por pacientes sanos del mismo nosocomio. Se realizó una evaluación médica para determinar tipo, tiempo y frecuencia del tratamiento y un examen oral para determinar la prevalencia de caries dental y el índice de dientes cariados, perdidos y obturados (CPOD). Resultados. Se encontró que la prevalencia de caries dental en el grupo control fue del 34,2 %, mientras, en el grupo casos, fue del 28,3 % (p = 0,094). Con respecto al índice de caries dental, el grupo control presentó CPOD de 4,73 ± 0,32, y el grupo casos, de 3,98 ± 0,31 (p = 0,08). Sin embargo, se evidenció que, a mayor tiempo de tratamiento con los inhaladores, el índice CPOD aumentaba significativamente (p = 0,04).Conclusiones. La medicación inhalatoria no incrementa la prevalencia de caries dental en pacientes pediátricos asmáticos. Sin embargo, existe una relación directa entre la duración del tratamiento y la prevalencia de caries dental


Introduction. Asthma is a chronic inflammatory disease that is highly prevalent among pediatric patients. The results about the effect of asthma on the rate of dental caries are contradictory. The objective of this study was to determine the prevalence of dental caries in asthma pediatric patients using inhaled drugs. Population and methods. Case-control study in a sample made up of pediatric patients who attended Centro Médico Naval "Cirujano Mayor Santiago Távara" between December 2014 and March 2015. Patients were divided into two groups: group A (cases) included asthma patients using inhalers as part of their treatment; group B (controls), healthy subjects who attended the same facility. A medical examination was done to determine the type, time, and frequency of treatment and an oral exam, to establish the prevalence of dental caries and the decayed, missing, and filled teeth (DMFT) index. Results. The prevalence of dental caries was 34.2 % in the control group and 28.3 % in the case group (p = 0.094). In relation to the rate of dental caries, the DMFT index in the control group was 4.73 ± 0.32, and 3.98 ± 0.31 in the case group (p = 0.08). However, it was evidenced that a longer duration of inhaler use led to a significantly higher DMFT index (p = 0.04).Conclusions. Inhaled drugs do not increase the prevalence of dental caries in asthma pediatric patients. However, there is a direct relationship between treatment duration and the prevalence of dental caries.

ABSTRACT

PURPOSE: Asthma control in older asthmatics is often less effective, which may be attributed to small airway dysfunction and poor inhalation technique. We compared the efficacy of 2 inhalers (fluticasone propionate/formoterol treatment using a pressurized metered-dose inhaler [p-MDI group] vs. fluticasone propionate/salmeterol treatment using a dry powder inhaler [DPI group]) in older asthmatics.METHODS: We conducted a 12-week, randomized, open-label, parallel-designed trial in older patients (over 55 years old) with moderate-to-severe asthma, and compared the efficacy and safety for asthma control between the 2 groups. Subgroup analyses on disease duration and air trapping were performed. Clinical parameters, including changes in lung function parameters, inhaler technique and adherence, were compared with monitoring adverse reactions between the 2 groups.RESULTS: A total of 68 patients underwent randomization, and 63 (30 in the p-MDI group and 33 in the DPI group) completed this study. The p-MDI group was non-inferior to the DPI group with regard to the rate of well-controlled asthma (53.3% vs. 45.5%, P < 0.001; a predefined non-inferiority limit of 17%). In subgroup analyses, the proportion of patients who did not reach well-controlled asthma in the p-MDI group was non-inferior to that in the DPI group; the difference was 12.7% among those with a longer disease duration (≥ 15 years) and 17.5% among those with higher air-trapping (RV/TLC ≥ 45%), respectively (a predefined non-inferiority limit of 17%, P < 0.001). No significant differences were observed in lung function parameters, inhalation techniques, adherence and adverse reactions between the 2 groups.CONCLUSION: These results suggest that the p-MDI group may be comparable to the DPI group in the management of older asthmatics in aspects of efficacy and safety.

ABSTRACT

Background: Research globally has shown that metered dose inhaler (MDI) technique is poor, with patient education and regular demonstration critical in maintaining correct use of inhalers. Patient information containing pictorial aids improves understanding of medicine usage; however, manufacturer leaflets illustrating MDI use may not be easily understood by low-literacy asthma patients. Aim: To develop and evaluate the outcome of a tailored, simplified leaflet on correct MDI technique in asthma patients with limited literacy skills. Setting: A rural primary health care clinic in the Eastern Cape, South Africa. Methods: Pictograms illustrating MDI steps were designed to ensure cultural relevance. The design process of the leaflet was iterative and consultative involving a range of health care professionals as well as patients. Fifty-five rural asthma patients were recruited for the pre-post design educational intervention study. Metered dose inhaler technique was assessed using a checklist, and patients were then educated using the study leaflet. The principal researcher then demonstrated correct MDI technique. This process was repeated at follow-up 4 weeks later. Results: The number of correct steps increased significantly post intervention from 4.6 ± 2.2 at baseline to 7.9 ± 2.7 at follow-up (p < 0.05). Statistically significant improvement of correct technique was established for 10 of the 12 steps. Patients liked the pictograms and preferred the study leaflet over the manufacturer leaflet. Conclusion: The tailored, simple, illustrated study leaflet accompanied by a demonstration of MDI technique significantly increased correct MDI technique in low-literacy patients. Patients approved of the illustrated, simple text leaflet, and noted its usefulness in helping them improve their MDI technique

ABSTRACT

ABSTRACT Objective: To demonstrate the most frequent errors in inhalation technique in patients with asthma undergoing treatment at a tertiary care hospital. Methods: A cross-sectional study with a convenience sample of asthma patients aged 18 years or over, treated at a pulmonology outpatient clinic of a tertiary care hospital. The assessment of inhalation technique of users of the dry powder inhalers Aerolizer®, Aerocaps and Diskus®, or metered-dose inhalers was based on the manufacturer's instructions for use of each inhaler device. Patients demonstrated the inhalation technique with empty inhaler devices, and it was considered correct when all stages were performed properly, or when errors probably did not interfere with the treatment outcome. Results: Among 71 participants, 43 (60.5%) performed inhalation technique incorrectly. Among metered-dose inhalers and dry powder inhalers users, inhalation technique errors were found in 84.2% and 51.9%, respectively (p=0.013). Errors were more frequent at the exhalation stage (67.4%), followed by breathing in (58.1%) and apnea (51.2%). In the group using dry powder inhalers, the most common errors occurred during exhalation and, for those using metered-dose inhalers, the most compromised stage was aspiration. Conclusion: Errors were more frequent among those using metered-dose inhalers compared with dry powder inhalers. Misconceptions are more common at the expiration stage among users of dry powder inhalers and in aspiration among those on metered-dose inhalers.


RESUMO Objetivo: Demonstrar os erros mais frequentes na técnica inalatória de pacientes com asma brônquica em tratamento em hospital terciário. Métodos: Estudo transversal, com amostra de conveniência de pacientes com asma, com 18 anos ou mais, em tratamento em ambulatório de pneumologia de um hospital terciário. A avaliação da técnica inalatória dos usuários dos dispositivos de pó seco Aerolizer ®, Aerocaps® ou Diskus®, ou de aerossóis dosimetrados teve como base as orientações da bula do fabricante de cada dispositivo inalatório. Os pacientes demonstraram a técnica inalatória com dispositivos inalatórios vazios, e ela foi considerada correta quando todas as etapas foram realizadas de forma apropriada, ou quando os equívocos provavelmente não interferiam no resultado do tratamento. Resultados: Entre os 71 participantes, 43 (60,5%) realizaram a técnica inalatória de forma incorreta. Dentre os usuários de aerossóis dosimetrados e dispositivos de pó seco, ocorreram erros de técnica inalatória em 84,2% e 51,9%, respectivamente (p=0,013). Os erros foram mais frequentes na etapa da expiração (67,4%), seguidos da aspiração (58,1%) e da apneia (51,2%). No grupo que usava dispositivos de pó seco, os erros mais comuns aconteceram na expiração e, nos que utilizavam aerossóis dosimetrados, a etapa mais comprometida foi a aspiração. Conclusão: Os erros foram mais frequentes entre os que usavam aerossóis dosimetrados em comparação com dispositivos de pó seco. Os equívocos foram mais comuns na etapa da expiração entre os usuários de dispositivos de pó seco e na aspiração entre os que usavam aerossóis dosimetrados.

ABSTRACT

RESUMO Objetivo: Comparar a eficácia no tratamento da asma pediátrica por nebulizador e inalador dosimetrado com uso de espaçador (MDI-espaçador), no emprego das técnicas de resgate de pacientes asmáticos atendidos em emergências pediátricas. Fontes de dados: Realizou-se uma revisão sistemática para identificar os principais estudos randomizados controlados que comparam a administração de broncodilatador (β-2 agonista) por meio das técnicas inalatórias nebulização e MDI-espaçador no tratamento da asma em unidades de emergência pediátrica. Foram pesquisadas as bases de dados PubMed, Scientific Electronic Library Online (SciELO) e ScienceDirect. Dois pesquisadores, de forma independente, aplicaram os critérios de elegibilidade, sendo incluídos na pesquisa apenas estudos randomizados controlados com o objetivo de comparar as técnicas inalatórias nebulização e MDI-espaçador no tratamento da asma em unidades de emergência pediátrica. Síntese dos dados: Foram pré-selecionados 212 artigos, dos quais apenas nove seguiram os critérios de elegibilidade e foram incluídos na metanálise. Os resultados apontam não existir diferenças nas técnicas inalatórias em nenhum dos quatro desfechos analisados: frequência cardíaca (diferença -Df: 1,99 [intervalo de confiança de 95% - IC95% -2,01-6,00]); frequência respiratória (Df: 0,11 [IC95% -1,35-1,56]); saturação de O2 (Df: -0,01 [IC95% -0,50-0,48]); e escore clínico de asma (Df: 0,06 [IC95% -0,26-0,38]). Conclusões: Os achados demonstram não haver diferenças na frequência cardiorrespiratória, na saturação de O2 nem nos escores de asma, na administração de β-2 agonista entre as técnicas inalatórias (nebulizador e MDI-espaçador) em pacientes asmáticos atendidos em emergências pediátricas.


ABSTRACT Objective: To compare the efficacy of pediatric asthma treatment by nebulizer and metered-dose inhaler with the use of a spacer (MDI-spacer) in rescue techniques for asthmatic patients assisted at pediatric emergency units. Data sources: A systematic review was conducted to identify the most relevant randomized controlled trials comparing the administration of a bronchodilator (β-2 agonist) by two inhalation techniques (nebulization and MDI-spacer) to treat asthma in children at pediatric emergency units. The following databases were searched: PubMed, Scientific Electronic Library Online (SciELO), and ScienceDirect. Two researchers independently applied the eligibility criteria, and only randomized controlled trials that compared both inhalation techniques (nebulization and MDI-spacer) for asthma treatment at pediatric emergency units were included. Data synthesis: 212 articles were pre-selected, of which only nine met the eligibility criteria and were included in meta-analysis. Results show no differences between inhalation techniques for any of the four outcomes analyzed: heart rate (difference - Df: 1.99 [95% confidence interval - 95%CI -2.01-6.00]); respiratory rate (Df: 0.11 [95%CI -1.35-1.56]); O2 saturation (Df: -0.01 [95%CI -0.50-0.48]); and asthma score (Df: 0.06 [95%CI -0,26-0.38]). Conclusions: The findings demonstrate no differences in cardiorespiratory frequency, O2 saturation, and asthma scores upon administration of β-2 agonist by both inhalation techniques (nebulization and MDI-spacer) to asthmatic patients assisted at pediatric emergency units.

ABSTRACT

Vídeos relacionados à técnica inalatória na asma são populares no YouTube, mas sua qualidade é questão de preocupação. Neste estudo objetivou-se avaliar vídeos que demonstram a técnica inalatória do inalador pressurizado acoplado ao espaçador, para crianças e adolescentes com asma, quanto a conformidade das diretrizes da Global Initiative for Asthma. Estudo exploratório, realizado em 11 de julho de 2017 usando os termos inalador pressurizado e aerossol dosimetrado. Os vídeos foram avaliados por três enfermeiras, independentes e experientes na área, quanto aos critérios de conteúdo, produção e usuários. Dentre os 492 vídeos encontrados, seis preencheram os critérios de elegibilidade. Ponto de destaque foi a demonstração incorreta da técnica inalatória em todos os vídeos e a pontuação inadequada na avaliação técnica e de conteúdo. As descobertas deste estudo mostram que os vídeos não são confiáveis e nem compatíveis com as diretrizes de asma e, portanto, não podem ser recomendados para fins educacionais.


Videos related to asthma inhaling technique are popular on YouTube, but their quality is concerning. In this study, we aimed to assess videos demonstrating the inhaling technique of the pressurized metered dose inhaler, attached to the spacer, for children and adolescents with asthma, according to the guidelines of the Global Initiative for Asthma. We conducted an exploratory study, on 11 July 2017 using the terms "inalador pressurizado" and "aerossol dosimetrado". Three independent nurses experienced in the field assessed the videos regarding content inclusion, production, and users. Within the 492 videos found, six met the eligibility criteria. The highlight point was the incorrect demonstration of the inhalation technique in all videos and the inadequate scoring for technique and content assessments. Our study findings show that videos are not reliable neither compatible with asthma guidelines and, therefore, they should not be recommended for educational purposes.

ABSTRACT

BACKGROUND: Proper education regarding inhaler usage and optimal management of chronic obstructive pulmonary disease (COPD) is essential for effectively treating patients with COPD. This study was conducted to evaluate the effects of a comprehensive education program including inhaler training and COPD management. METHODS: We enlisted 127 patients with COPD on an outpatient basis at 43 private clinics in Korea. The patients were educated on inhaler usage and disease management for three visits across 2 weeks. Physicians and patients were administered a COPD assessment test (CAT) and questionnaires about the correct usage of inhalers and management of COPD before commencement of this program and after their third visit. RESULTS: The outcomes of 127 COPD patients were analyzed. CAT scores (19.6±12.5 vs. 15.1±12.3) improved significantly after this program (p<0.05). Patients with improved CAT scores of 4 points or more had a better understanding of COPD management and the correct technique for using inhalers than those who did not have improved CAT scores (p<0.05). CONCLUSION: A comprehensive education program including inhaler training and COPD management at a primary care setting improved CAT scores and led to patients' better understanding of COPD management.

ABSTRACT

Objective: To describe the frequency of popular myths about and features of asthma treatment in children and adolescents in an urban area in southern Brazil. Methods: The parents or legal guardians of public school students (8-16 years of age) completed a specific questionnaire regarding their understanding of asthma, asthma control, and treatment characteristics. The sample included parents or legal guardians of students with asthma (n = 127) and healthy controls (n = 124). Results: The study involved 251 parents or legal guardians, of whom 127 (68.5%) were the mothers and 130 (51.8%) were White. The mean age of these participants was 38.47 ± 12.07 years. Of the participants in the asthma and control groups, 37 (29.1%) and 26 (21.0%), respectively, reported being afraid of using asthma medications, whereas 61 (48%) and 56 (45.2%), respectively, believed that using a metered dose inhaler can lead to drug dependence. However, only 17 (13.4%) and 17 (13.7%) of the participants in the asthma and control groups, respectively, reported being afraid of using oral corticosteroids. In the asthma group, 55 students (43.3%) were diagnosed with uncontrolled asthma, only 41 (32.3%) had a prescription or written treatment plan, and 38 (29.9%) used asthma medications regularly. Conclusions: Popular myths about asthma treatment were common in our sample, as were uncontrolled asthma and inappropriate asthma management. Further studies in this field should be conducted in other developing countries, as should evaluations of pediatric asthma treatment programs in public health systems.


Objetivo: Descrever a frequência de mitos populares e as características do tratamento em asma em crianças e adolescentes em uma amostra urbana no sul do Brasil. Métodos: Foi aplicado um questionário específico, contendo perguntas sobre entendimento da doença, controle da asma e características do tratamento a pais/responsáveis de escolares da rede pública (8-16 anos de idade) com diagnóstico de asma (n = 127) e de controles saudáveis (n = 124). Resultados: Participaram do estudo 251 pais/responsáveis, com predomínio de mães como acompanhantes dos escolares (n = 127; 68,5%) e de etnia caucasiana (n = 130; 51,8%), com média de idade de 38,47 ± 12,07 anos. Sobre os mitos, 37 (29,1%) dos participantes do grupo asma e 26 (21,0%) dos do grupo controle relataram possuir receio de utilizar medicamentos para asma, e 61 (48%) e 56 (45,2%), respectivamente, acreditam que os inaladores pressurizados podem levar a dependência ao fármaco. No entanto, apenas 17 (13,4%) dos participantes do grupo asma e 17 (13,7%) dos do grupo controle relataram ter receio de utilizar corticoide oral. A ausência de controle da asma foi detectada em 55 (43,3%) dos escolares no grupo asma, apenas 41 (32,3%) possuíam uma receita ou um plano por escrito de como tratar da asma e 38 (29,9%) fazia uso contínuo de medicamentos para a doença. Conclusões: A presença de mitos populares sobre o tratamento da asma, a falta de controle da doença e seu manejo inadequado mostraram ser elevados nesta amostra. Nossos achados apontam para a necessidade de novos estudos nesse campo em países em desenvolvimento e de uma avaliação dos programas de manejo da asma pediátrica na saúde pública.

ABSTRACT

Objective: Inhaler technique comprises a set of procedures for drug delivery to the respiratory system. The oral inhalation of medications is the first-line treatment for lung diseases. Using the proper inhaler technique ensures sufficient drug deposition in the distal airways, optimizing therapeutic effects and reducing side effects. The purposes of this study were to assess inhaler technique in pediatric and adult patients with asthma; to determine the most common errors in each group of patients; and to compare the results between the two groups.Methods: This was a descriptive cross-sectional study. Using a ten-step protocol, we assessed inhaler technique in 135 pediatric asthma patients and 128 adult asthma patients.Results: The most common error among the pediatric patients was failing to execute a 10-s breath-hold after inhalation, whereas the most common error among the adult patients was failing to exhale fully before using the inhaler.Conclusions: Pediatric asthma patients appear to perform most of the inhaler technique steps correctly. However, the same does not seem to be true for adult patients.


Objetivo: La técnica inhalatoria es un conjunto de procedimientos mediante el cual se administra un fármaco al sistema respiratorio. Se caracteriza por ser utilizada como primera línea para tratar las enfermedades pulmonares. Su correcta ejecución garantiza un mayor depósito del fármaco en la vía aérea distal, optimizando sus efectos terapéuticos y disminuyendo los efectos secundarios. Los objetivos de este estudio son describir la ejecución de la técnica inhalatoria en un grupo de pacientes asmáticos pediátricos versus un grupo de pacientes asmáticos adultos, definir los errores más comunes en cada grupo de pacientes y comparar los resultados entre ambos grupos.Métodos: Estudio descriptivo, transversal. Se evaluó la técnica inhalatoria según un protocolo de diez pasos en 135 pacientes asmáticos pediátricos y 128 pacientes asmáticos adultos.Resultados: Se encontró que el error más común en los pacientes pediátricos fue no realizar una apnea de 10 s después de la inhalación, mientras que en los pacientes adultos el principal error fue no exhalar completamente antes de aplicar el inhalador.Conclusiones: Se determinó que los pacientes asmáticos pediátricos cumplen con la mayoría de los pasos para una correcta técnica inhalatoria, lo que no se observa en los pacientes adultos.

ABSTRACT

AbstractObjective: To validate two scores quantifying the ability of patients to use metered dose inhalers (MDIs) or dry powder inhalers (DPIs); to identify the most common errors made during their use; and to identify the patients in need of an educational program for the use of these devices.Methods: This study was conducted in three phases: validation of the reliability of the inhaler technique scores; validation of the contents of the two scores using a convenience sample; and testing for criterion validation and discriminant validation of these instruments in patients who met the inclusion criteria.Results: The convenience sample comprised 16 patients. Interobserver disagreement was found in 19% and 25% of the DPI and MDI scores, respectively. After expert analysis on the subject, the scores were modified and were applied in 72 patients. The most relevant difficulty encountered during the use of both types of devices was the maintenance of total lung capacity after a deep inhalation. The degree of correlation of the scores by observer was 0.97 (p < 0.0001). There was good interobserver agreement in the classification of patients as able/not able to use a DPI (50%/50% and 52%/58%; p < 0.01) and an MDI (49%/51% and 54%/46%; p < 0.05).Conclusions: The validated scores allow the identification and correction of inhaler technique errors during consultations and, as a result, improvement in the management of inhalation devices.


ResumoObjetivo: Validar dois escores para medir a habilidade de pacientes em utilizar inaladores pressurizados (IPs) ou inaladores de pó (IPos), verificar os erros mais comuns na sua utilização e identificar os pacientes que necessitam de um programa educacional para o uso desses dispositivos.Métodos: Este estudo foi realizado em três etapas: validação da confiabilidade dos escores de uso dos dispositivos inalatórios; validação do conteúdo dos escores utilizando-se uma amostra de conveniência; e realização de testes para a validação de critério e a validação discriminante desses instrumentos em pacientes que preenchiam os critérios de inclusão do estudo.Resultados: A amostra de conveniência foi composta por 16 pacientes, e houve discordância interobservador em 19% e 25% para os escores de IPo e IP, respectivamente. Após a análise de expertos no assunto, os escores sofreram modificações e foram aplicados em 72 pacientes. A dificuldade mais relevante no uso de ambos os dispositivos foi a manutenção da capacidade pulmonar total após inspiração profunda. O grau de correlação dos escores por observador foi de 0,97 (p < 0,0001). Houve boa concordância interobservador na classificação dos pacientes como aptos/não aptos para uso de IPo (50%/50% e 52%/58%; p < 0,01) e de IP (49%/51% e 54%/46%; p < 0,05).Conclusões: Os escores validados permitem identificar e corrigir os erros da técnica inalatória ao longo das consultas e, em consequência, melhorar o manejo dos dispositivos para inalação.

ABSTRACT

Objetivo: Comparar el efecto del tratamiento con inhaladores versus nebulizadores de las crisis asmáticas leves y moderadas en niños menores de cinco años. Metodología: Se escogieron al azar dos grupos de niños menores de cinco años con crisis de asma leve y moderada según el score de Bierman y Pierson modificado por Tal. A un grupo se aplicó tratamiento con Inhaladores de dosis medida (Ventolín) con aerocámara a 2 puffs cada 20 minutos por 3 veces y a otro grupo se aplicó el tratamiento estándar de Nebulizaciones con Salbutamol (Ventolín) a 0.15mg/kg/dosis cada 20 minutos por 3 dosis. Luego se recogieron los hallazgos en una ficha de recolección de datos(la ficha de investigación de Asma-SOBA del servicio de Pediatría del Hospital Nacional Dos de Mayo) para analizarlos y compararlos. Resultados: Encontramos que después de aplicar el tratamiento de B2 agonistas tanto con Inhaladores de dosis medida como con Nebulizaciones hubo mejoría clínica No hubo ninguna hospitalización a causa de las crisis. Conclusiones: El efecto del tratamiento tanto con inhaladores de dosis medida como con nebulizaciones fue similar. La tasa de hospitalización fue de cero.


Objective: To compare the efficacy of the treatment of mild and moderate asthma attack using metered dose inhalers (MDI) versus nebulizers for children under five years old in Pediatric Emergency Hospital Nacional Dos de Mayo, Lima, Peru. Methods: Two groups of children under five years old with acute mild to moderate asthma were chosen at random, according to Bierman and Pierson score modified by Tal. One group was given treatment with metered dose inhalers (MDI) (Ventolin) with holding chamber 2 puffs every 20 minutes three times and the other received standard treatment with nebulizers Salbutamol (Ventolin) to 0.15 mg/kg/ dose every 20 minutes for three times with the possibility of moving to a second phase if necessary. Findings were collected in a data collection sheet then analyze and compare them. Results: We found that after applying both MDI as nebulizers was clinical improvement with a slight advantage of inhalers. Hospitalization rate was zero. Conclusions: Treatment with MDI is statistically similar to that of nebulizers in asthma attacks mild to moderate in children under five years in the service of Pediatric Emergency Hospital Nacional Dos de Mayo.

ABSTRACT

<p><b>INTRODUCTION</b>This study aimed to evaluate whether multimedia counselling (MC) using a touchscreen computer is as effective and time-efficient as conventional counselling (CC) in promoting correct metered-dose inhaler (MDI) technique, with or without the valved holding chamber (VHC).</p><p><b>METHODS</b>Participants in the MDI-only and MDI-with-VHC groups were randomly assigned to the MC group or CC group. No blinding was imposed. Inhalation technique was assessed using checklists before and after counselling. Time spent on counselling was determined for all participants, while time taken to perfect the technique was determined only for participants who achieved perfect technique within one hour.</p><p><b>RESULTS</b>The CC group had more elderly participants than the MC group, but the difference was not significant. MDI-only and MDI-with-VHC users showed significant improvement in their inhaler technique after multimedia (44.5 ± 28.0% and 44.1 ± 14.4%, respectively) and conventional counselling (36.8 ± 20.5% and 37.0 ± 14.6%, respectively). No significant difference in MDI technique enhancement was found between the two groups. Although no significant difference was found between the MC and CC groups with regard to the time spent on counselling and the time taken to perfect the technique, the average time spent on counselling was longer for MDI-only users. MDI-only users had 13.5 times the odds of failing to achieve perfect technique compared to MDI-with-VHC users (95% confidence interval 1.50-121.32, p = 0.020).</p><p><b>CONCLUSION</b>MC and CC significantly improved MDI technique. Both methods showed comparable short-term effectiveness and time-efficiency in MDI technique education. VHC was beneficial, especially for MDI-users with hand-lung coordination problems.</p>

ABSTRACT

OBJECTIVE: To identify incorrect inhaler techniques employed by patients with respiratory diseases in southern Brazil and to profile the individuals who make such errors. METHODS: This was a population-based, cross-sectional study involving subjects ≥ 10 years of age using metered dose inhalers (MDIs) or dry powder inhalers (DPIs) in 1,722 households in the city of Pelotas, Brazil. RESULTS: We included 110 subjects, who collectively used 94 MDIs and 49 DPIs. The most common errors in the use of MDIs and DPIs were not exhaling prior to inhalation (66% and 47%, respectively), not performing a breath-hold after inhalation (29% and 25%), and not shaking the MDI prior to use (21%). Individuals ≥ 60 years of age more often made such errors. Among the demonstrations of the use of MDIs and DPIs, at least one error was made in 72% and 51%, respectively. Overall, there were errors made in all steps in 11% of the demonstrations, whereas there were no errors made in 13%.Among the individuals who made at least one error, the proportion of those with a low level of education was significantly greater than was that of those with a higher level of education, for MDIs (85% vs. 60%; p = 0.018) and for DPIs (81% vs. 35%; p = 0.010). CONCLUSIONS: In this sample, the most common errors in the use of inhalers were not exhaling prior to inhalation, not performing a breath-hold after inhalation, and not shaking the MDI prior to use. Special attention should be given to education regarding inhaler techniques for patients of lower socioeconomic status and with less formal education, as well as for those of advanced age, because those populations are at a greater risk of committing errors in their use of inhalers. .


OBJETIVO: Conhecer os erros na técnica de uso de dispositivos inalatórios empregada por pacientes com doenças respiratórias no sul do Brasil e o perfil daqueles que possuem dificuldades em realizá-la. MÉTODOS: Estudo transversal, de base populacional, com indivíduos com idade ≥ 10 anos e em uso de inaladores pressurizados (IPrs) ou inaladores de pó (IP) em 1.722 domicílios de Pelotas (RS). RESULTADOS: Foram incluídos 110 indivíduos que utilizavam 94 IPrs e 49 IP. Os principais erros no uso dos IPrs e IP foram não expirar antes da inalação (66% e 47%, respectivamente), não fazer uma pausa inspiratória após a inalação (29% e 25%) e não agitar o IPr antes do uso (21%). Os indivíduos com idade ≥ 60 anos mais frequentemente cometeram erros. Das demonstrações de uso do IPr e IP, respectivamente, 72% e 51% apresentaram ao menos um erro, enquanto 13% das demonstrações foram plenamente corretas e 11% apresentaram erros em todas as fases. A proporção de indivíduos com menor nível de escolaridade que cometeram ao menos um erro foi significativamente maior do que a daqueles com maior nível de escolaridade tanto no uso de IPrs (85% vs. 60%; p = 0,018) quanto no de IPs (81% vs. 35%; p = 0,010). CONCLUSÕES: Nesta amostra, os principais erros cometidos no uso dos inaladores foram não realizar a expiração antes da inalação, não fazer a pausa inspiratória após a inalação e não agitar o IPr. Pacientes com menor nível socioeconômico e educacional, assim como aqueles com idade avançada, merecem especial atenção na educação sobre a realização da técnica inalatória, pois apresentam um maior risco de cometer erros durante o uso dos inaladores. .

ABSTRACT

The most common treatment for asthma is transferring the drug into the lungs by inhaler devices. Besides, correct use of inhaled medication is required for effectiveness of pharmacotherapy. Thus, it is necessary to train the patients how to use Metered Dose Inhaler [MDI]. This study aimed to determine the effect of training about MDI usage with or without spacer on maximum expiratory flow rate and inhaler usage skills in asthmatic patients. This randomized clinical trial was conducted on 90 asthmatic patients who were randomly divided into inhalation technique group with spacer, inhalation technique group without spacer, and a control group. Then, the Peak Expiratory Flow Rate [PEFR] was measured using a peak flow meter, as a basic test. In addition, the patients' functional skills of inhalation technique were assessed using two checklists. Afterwards, 3 sessions of training were arranged for both groups. PEFR and the ability to use the MDI were evaluated immediately and 1 month after the intervention. Finally, the data were entered into the SPSS statistical software [v. 18] and analyzed using independent t-test and repeated measures ANOVA. After the intervention, MDI usage skills improved in the two intervention groups compared to the control group [P<0.001]. In addition, a significant difference was found between the intervention groups and the control group regarding the mean of PEFR after the intervention [P<0.001]. However, no significant difference was observed between the two intervention groups [P=0.556]. According to the results, providing appropriate training for asthmatic patients increased MDI usage skills, and both methods of inhalation [with or without spacer] could improve the PEFR among the patients

ABSTRACT

Beclomethasone dipropionate CFC free inhalation formulations were developed with a view to treat asthma prophylactically. Dry powder inhalers (DPI) for beclomethasone dipropionate were prepared with different grades of lactose monohydrate. The influence of carrier and overages on performance of DPI was studied. Metered dose inhalers (MDI) with HFA based propellants were formulated with various doses, overages and different concentrations of alcohol. Formulated DPI and MDI were evaluated for various official and unofficial quality control tests. The influence of over doses on valve delivery, effect of overages on emitted dose and influence of alcohol on spray pattern from MDI were studied. The better fine particle fraction and emitted dose were obtained from the DPI formulated with 10:90 ratio of fine lactose: coarse lactose and with 20% w/w overages. The studies on MDI revealed that the 15% of overdoses are required for effective valve delivery and 20% overages are required for 100% drug delivery. 5-10%v/v alcohol was found to be preferable to get optimum emitted dose and fine particle fraction.


Desenvolveram-se formulações por inalação de dipropionato de beclometasona, livres de CFC, com o objetivo de tratar a asma profilaticamente. Prepararam-se inaladores de pó seco (DPI) para o dipropionato de beclometasona com diferentes gradações de lactose monoidratada. Estudou-se a influência do transportador e dos excessos de fármaco em relação ao rotulado no desempenho do DPI. Inaladores de dose calibrada (MDI) com propelentes à base de hidrofluoralcanos (HFA) foram formulados com várias doses, excessos de fármaco em relação ao rotulado e diferentes concentrações de álcool. Avaliaram-se as DPI e MDI formuladas por vários métodos oficiais e não oficiais de controle de qualidade. Estudaram-se a influência da superdosagem na liberação da válvula, o efeito dos excessos na dose emitida e a influência do álcool no padrão do spray do MDI. Obtiveram-se a melhor partícula fina e a dose emitida do DPI formulado com proporção de 10:90 de lactose fina:lactose grossa e 20% p/p de excesso. Os estudos em MDI revelaram que 15% de sobredose são requeridos para a liberação efetiva da válvula e 20% de excessos, para a liberação de 100% dos fármacos. Álcool a 5-10% v/v permitiu alcançar ótima dose emitida e fração de partícula fina.

ABSTRACT

OBJETIVO: Avaliar o manuseio dos dispositivos pelos asmáticos graves acompanhados no Programa para o Controle da Asma e Rinite Alérgica na Bahia (ProAR), registrando a frequência dos seus erros em passos essenciais e a relação desses com a falta de controle da asma. MÉTODOS: Estudo de corte transversal com 467 pacientes em acompanhamento no ProAR, na cidade de Salvador (BA). Os dispositivos avaliados foram inalador dosimetrado (ID), em isolado ou com espaçador, e inalador de pó seco (IPS; Pulvinal® ou Aerolizer®). A avaliação da técnica inalatória foi realizada através de uma lista de verificação, sendo solicitado ao paciente que demonstrasse o uso para que um entrevistador observasse todos os passos realizados. Para a avaliação do controle da asma, utilizou-se o questionário de controle da asma com seis questões. RESULTADOS: A maioria dos pacientes demonstrou técnicas inalatórias adequadas no uso dos dispositivos. Poucos erros foram observados na etapa essencial "coordenar disparo e inspiração" no uso de ID isolado e com espaçador (em 5,2 por cento e em 9,1 por cento dos pacientes, respectivamente). No uso de Pulvinal®, 39 por cento dos pacientes não realizaram uma inspiração rápida e profunda, comparados a somente 5,8 por cento no uso de Aerolizer®. Dos pacientes que utilizavam apenas Aerolizer®, 71,3 por cento realizaram adequadamente todos os passos essenciais e estavam controlados. CONCLUSÕES: A maioria dos pacientes desta amostra, os quais eram submetidos a verificações periódicas da técnica inalatória no programa, utilizavam adequadamente os dispositivos. A técnica inalatória adequada está associada ao controle dos sintomas.


OBJECTIVE: To evaluate the use of inhaler devices by patients with severe asthma treated via the Programa para o Controle da Asma e Rinite Alérgica na Bahia(ProAR, Bahia State Asthma and Allergic Rhinitis Control Program), recording the frequency of their errors in performing key steps and the relationship between such errors and the lack of asthma control. METHODS: A cross-sectional study involving 467 patients enrolled in the ProAR in the city of Salvador, Brazil. The devices evaluated were metered dose inhalers (MDIs), with or without a spacer, and dry powder inhalers (DPIs; Pulvinal® or Aerolizer®). For the assessment of the inhalation technique, a checklist was used; the patients were asked to demonstrate the technique so that an interviewer could observe all of the steps performed. For the assessment of asthma control, we used the 6-item asthma control questionnaire. RESULTS: Most of the patients showed appropriate inhalation techniques when using the devices. When using an MDI, few patients made mistakes in the key step of "coordinating activation and inhalation" (5.2 percent and 9.1 percent with and without the use of a spacer, respectively). During Pulvinal® use, 39 percent of the patients did not inhale quickly and deeply, compared with only 5.8 percent during Aerolizer® use. Of the patients that made use of Aerolizer® alone, 71.3 percent appropriately performed all of the essential steps, and their asthma was controlled. CONCLUSIONS: Most of the patients in this sample, all of whom had been submitted to periodic checks of their inhalation technique (as part of the program), used the devices appropriately. Proper inhalation technique is associated with asthma symptom control.

ABSTRACT

Objective: To evaluate the effect of a theoretical and practical guidance on knowledge of pediatricians regarding the use of metered dose inhalers with spacers. To identify major deficiencies, correct them and train these physicians on the correct use of the devices. Methods: Pediatricians who participated in a theoreticalpractical program focusing on the use of inhaler devices answered a questionnaire with five questions about the use of these devices before and after the program. A comparison of the scores obtained in the pre- and post-training tests was performed by Wilcoxon test for related samples, and a significance level of 0.05 was adopted. Results: Twenty pediatricians performed pre- and post-training tests. The performance of pediatricians in the post-training test was significantly better than baseline (p<0.001). Conclusion: A brief orientation program for pediatricians significantly improved their knowledge on the use of metered-dose inhalers with spacers, which may translate into an improvement in quality and quantity of prescriptions of these devices in clinical practice. The questions with higher rates of errors in the pre-training test were the questions about the waiting time between two sprays in successive applications and about the correct way to attach the inhaler to the spacer, both with high levels of success in the post-training test.


Objetivo: Avaliar o efeito de uma orientação teórico-prática sobre o conhecimento de pediatras a respeito do uso de inaladores dosimetrados com espaçadores. Detectar as principais deficiências, corrigi-las e capacitar esses médicos para a correta utilizaçãodesses inaladores. Métodos: Pediatras que participaram de um curso teórico-prático a respeito do uso de dispositivos inalatórios responderam a um questionário com cinco perguntas sobre o uso desses dispositivos antes e após o curso. A comparação entre asnotas obtidas no pré e no pós-teste foi feita por meio do teste de Wilcoxon para amostras relacionadas, sendo adotado um nível de significância de 0,05. Resultados: Vinte pediatras realizaram o pré e o pós-teste. O desempenho dos médicos no pós-teste foi significativamente melhor que o inicial (p<0,001). Conclusão: Um breve programa de orientação a pediatras melhorou de forma significativa o conhecimento desses médicos a respeito do uso de inaladores dosimetrados com espaçadores, fato que pode se traduzir em uma melhora na qualidade e na quantidade de prescrições desses dispositivos na prática clínica. As questões com maiores índices de erros no pré-teste foram a relativa ao tempo necessário entre dois jatos em aplicações sucessivas e a que diz respeito à maneira correta de se acoplar o inalador ao espaçador, todas com altos níveis de acertos no pós-teste.
