Evolución del consumo de antibióticos a nivel extrahospitalario en Asturias, España (2005-2018) / Evolution of antibiotic consumption in pediatric outpatients of Asturias, Spain (2005-2018)

Introducción: El consumo de antibióticos en España es elevado y más del 90% de las prescripciones se realizan en ámbito extrahospitalario. La exposición a antibióticos en la edad infantil es alta. El objetivo de este estudio es describir la evolución del consumo extrahospitalario de antibióticos en la población pediátrica del Principado de Asturias entre 2005 y 2018.Material y métodos: Estudio descriptivo y retrospectivo del consumo de antibacterianos de uso sistémico (grupo J01 de la clasificación ATC, Anatomical Therapeutic Chemical Classification) en ámbito extrahospitalario en la población pediátrica (0-13 años) del Principado de Asturias entre 2005 y 2018. Se compara el consumo, medido en número de dosis diarias definidas (DDD) por 1.000 habitantes y día (DHD), en 3 periodos de tiempo.Resultados: El consumo medio de antibacterianos en la población pediátrica asturiana (2005-2018) fue de 14 DHD (IC95% 13,4-14,6), con un aumento hasta 2009 (15,2 DHD) y descenso a partir de 2015 (11,9 DHD en 2018). A lo largo del estudio se detectó: 1) un aumento del consumo de amoxicilina (p=0,027), que supera al de amoxicilina-clavulánico desde el año 2011; 2) un consumo estable de macrólidos, con un aumento de azitromicina (p<0,001) y un descenso de claritromicina (p=0,001); 3) un descenso del consumo de cefalosporinas (p<0,001); 4) un aumento del consumo de quinolonas (p=0,002).Conclusiones: El consumo de antibióticos a nivel extrahospitalario en la población pediátrica del Principado de Asturias entre los años 2005 y 2018 ha experimentado un descenso mantenido en los últimos años y una mejora evolutiva del patrón de uso.

Introduction: Data about consumption of antibiotics in Spain are worrisome. They are mainly prescribed in the community sector and there is a high exposure to antibiotics in the pediatric population. The aim of this study is to describe the evolution of antibiotic consumption in the pediatric population of Asturias during 2005-2018 period.Material and methods: Retrospective and descriptive study using data about consumption of antibacterial agents for systemic use (J01 group of the Anatomical Therapeutic Chemical Classification) in pediatric outpatients in Principado de Asturias between 2005 and 2018. Data, expressed as defined daily dose (DDD) per 1000 inhabitants per day (DID), in three periods were compared.Results: Mean antibiotic consumption in pediatric outpatients in Principado de Asturias (2005-2018) was 14 DID (CI95% 13.4-14.6). Consumption increased until 2009 (15.2 DID) and decreased from 2015 onwards (11.9 DID in 2018). Remarkable data along the study were: 1) increase in amoxicillin consumption (p=0.027), that have exceeded that of amoxicillin-clavulanate since 2011; 2) steady consumption of macrolides, with an increase in azithromycin (p<0.001) and a decrease in clarithromycin (p=0.001); 3) reduction of cephalosporins consumption (p<0.001); 4) increase in quinolones consumption (p=0.002).Conclusions: Global antibiotic consumption in pediatric outpatients in Principado de Asturias between 2005 and 2018 has experienced a constant decrease lately and an improvement in patterns of antibacterial use.

Variation in Antiosteoporotic Drug Prescribing and Spending Across Spain. A Population-Based Ecological Cross-Sectional Study.

Introduction: Evidence has shown that utilization of antiosteoporotic medications does not correspond with risk, and studies on other therapies have shown that adequacy of pharmaceutical prescribing might vary between regions. Nevertheless, very few studies have addressed the variability in osteoporotic drug consumption. We aimed to describe variations in pharmaceutical utilization and spending on osteoporotic drugs between Health Areas (HA) in Spain. Methods: Population-based cross-sectional ecological study of expenditure and utilization of the five therapeutic groups marketed for osteoporosis treatment in Spain in 2009. Small area variation analysis (SAVA) methods were used. The units of analysis were the 168 HA of 13 Spanish regions, including 7.2 million women aged 50 years and older. The main outcomes were the defined daily dose (DDD) per 1000 inhabitants and day (DDD/1000/Day) dispensed according to the pharmaceutical claims reimbursed, and the expenditure on antiosteoporotics at retail price per woman ≥50 years old and per year. Results: The average osteoporosis drug consumption was 116.8 DDD/1000W/Day, ranging from 78.5 to 158.7 DDD/1000W/Day between the HAs in the 5th and 95th percentiles. Seventy-five percent of the antiosteoporotics consumed was bisphosphonates, followed by raloxifene, strontium ranelate, calcitonins, and parathyroid hormones including teriparatide. Regarding variability by therapeutic groups, biphosphonates showed the lowest variation, while calcitonins and parathyroid hormones showed the highest variation. The annual expenditure on antiosteoporotics was €426.5 million, translating into an expenditure of €59.2 for each woman ≥50 years old and varying between €38.1 and €83.3 between HAs in the 5th and 95th percentiles. Biphosphonates, despite accounting for 79% of utilization, only represented 63% of total expenditure, while parathyroid hormones with only 1.6% of utilization accounted for 15% of the pharmaceutical spending. Conclusion: This study highlights a marked geographical variation in the prescription of antiosteoporotics, being more pronounced in the case of costly drugs such as parathyroid hormones. The differences in rates of prescribing explained almost all of the variance in drug spending, suggesting that the difference in prescription volume between territories, and not the price of the drugs, is the main source of variation in this setting. Data on geographical variation of prescription can help guide policy proposals for targeting areas with inadequate antiosteoporotic drug use.

Variabilidad e idoneidad del tratamiento antiasmático en pediatría de atención primaria / Variability and suitability of anti-asmathic treatment in pediatric primary health care

OBJETIVO: Analizar los patrones de consumo y las características de las prescripciones de fármacos antiasmáticos en pediatría de atención primaria. DISEÑO: Estudio observacional retrospectivo. Emplazamiento: Pediatría de atención primaria, Asturias, España. PARTICIPANTES: Prescripciones para aparato respiratorio en <14 años durante el año 2011. Mediciones principales: Análisis del consumo de fármacos por áreas sanitarias y centros de salud, a partir de la base de datos de facturación del Servicio de Salud del Principado de Asturias, utilizando el número de DDD/1.000 niños/día (DHD) de cada grupo farmacológico. Revisión de historias clínicas de 6 consultas de pediatría de atención primaria del área sanitaria V para analizar la idoneidad de las prescripciones de los pediatras según la recomendación vigente. RESULTADOS: El principal grupo farmacológico han sido los broncodilatadores (17,14DHD), con predominio de la vía inhalatoria (14DHD). Se observa un uso mayoritario de corticoides inhalados (4,83DHD), siendo la fluticasona el principal principio activo. El 94,3% de los broncodilatadores orales y más del 50% de las prescripciones de mepiramina se consideran inadecuadas. Dentro de las prescripciones no autorizadas en ficha técnica un 17,8% corresponden al salbutamol oral, utilizado en menores de 2 años. CONCLUSIONES: El uso de fármacos antiasmáticos es elevado en Asturias, lo cual puede relacionarse con la prevalencia local de asma. Se observa variabilidad en la prescripción entre áreas sanitarias y centros de salud. La adecuación de las prescripciones estaría dentro de las recomendaciones vigentes, salvo en el caso del uso de fármacos broncodilatadores por vía oral

OBJECTIVE: To analyse the use patterns and the characteristics of anti-asmathic prescriptions in pediatric primary health care. DESIGN: Observational and retrospective study. LOCATION: Pediatric primary health care, Asturias, Spain. PARTICIPANTS: Drug prescriptions in respiratory diseases in children (<14 years old) during 2011. Principal measurements: Data obtained from the billing database of the Regional Health Service of Asturias and analysed by sanitary district and primary health centres, calculating the number of DDD/1.000 children/day (DHD). Clinical records audit in 6 paediatric surgeries of sanitary district V to evaluate the suitability of the drug prescriptions to the current recommendations. RESULTS: The main group were bronchodilators (17.14DHD) with predominance of the inhaled route (14DHD). We observe more use of inhaled corticoids (4.83DHD), with an important use of fluticasone. We considered un-suitable 94.3% oral bronchodilators, and >50% of mepiramine prescriptions. We registered off-label prescriptions, 17.8% of them were about oral salbutamol, being used in children <2 years old. CONCLUSIONS: The use of anti-asthmatic drugs in our region is high, maybe it's related to the asthma prevalence. We observed variability between sanitary districts and health centres. The prescription patterns are closed to the current recommendation, except in the case of oral bronchodilators
