RESUMO
Fundamento: El objetivo de este estudio ha sido realizar un análisis de la evolución de la pandemia por el virus de la gripe (H1N1) 2009 en la Comunidad Autónoma de La Rioja tanto en atención primaria como en hospitalaria. Métodos: El periodo de estudio incluyó desde la semana 28-2009 hasta la 3-2010. La información de los casos de gripe se obtuvo de las bases informatizadas de atención primaria (OMI), de los listados remitidos por los servicios hospitalarios de medicina preventiva, del laboratorio de referencia de La Rioja y de los formularios de notificación individual. Se realizó una descripción de los casos según distribución por semana, sexo, edad, factores de riesgo, evolución y complicaciones. Se utilizó la regresión binaria logística para estimar las odds ratios ajustadas y su intervalo de confianza al 95%, de recibir tratamiento antiviral según factores de riesgo. Resultados: Hasta la semana epidemiológica 3 de 2010 se declararon a través del sistema OMI de atención primaria 7.096 casos de sospecha de gripe (H1N1) 2009, fueron hospitalizados 111 casos con diagnóstico confirmado por laboratorio. Requirieron atención en cuidados intensivos 5 (4,5%) y 2 fallecieron. Todos ellos presentaban factores de riesgo. Ninguno de los niños ni de las mujeres embarazadas hospitalizados precisaron ingreso en cuidados intensivos. Conclusiones: Durante la pandemia la gripe (H1N1) 2009 fue una enfermedad propia de la población pediátrica y joven, apareciendo con menor frecuencia en las personas mayores de 60 años. La evolución clínica en La Rioja cursó de forma leve en la mayoría de las personas diagnosticados(AU)
Background: The aim of this study has been to analyze the development of pandemic influenza (H1N1) 2009 in La Rioja autonomous (cases in primary healthcare and cases hospitalized). Methods: We have included all cases with 2009 H1N1 influen-za from week 28-2009 to 3-2010. The main information was collected through Primary Healthcare databases (OMI), lists of Preventive Medicine Hospital Departments, reference laboratory and individual standardized forms. This information was analyzed and described according to week, sex, age, comorbidities, clinical development and medical complication. We explore the association of to antiviral treatment and risk factors. This association was assessed using odds ratios (OR) and 95% confidence interval (CI). Adjustment for confounders was performed using unconditional logistic regression to estimate the odds ratio (OR) and 95% confidence intervals (CI). Results: From 29-2009 week to 3-2010 week, a total of 7096 pandemic influenza A(H1N1) cases were notified from Primary Healthcare and 111 laboratory confirmed severe cases were admitted to hospital. Five cases were admitted to an ICU (4,5%) and 2 cases died. All this patients had comorbidities. None of children and pregnant female were admitted to an ICU. Conclusions: Children and young person have been population with more cases of pandemic influenza (H1N1) 2009. Clinical evolution of pandemic in the majority cases in La Rioja, has been mild(AU)
