Epidemiología de la anemia en adultos: estudio observacional de base poblacional / Epidemiology of anemia in adults: A population based study

Objetivo Determinar la prevalencia de la anemia y las características definitorias de los individuos que la padecen. Diseño Estudio observacional descriptivo de base poblacional. Variables extraídas de la base de datos informatizada de historias clínicas de atención primaria. Emplazamiento El presente estudio se realizó en la región sanitaria Metropolitana Nord, Barcelona. Participantes Pacientes con anemia evaluada mediante hemoglobina durante el año 2019. Criterios inclusión: mayores de 14 años, con determinaciones de hemoglobina por debajo del valor recomendado por la OMS. Criterio exclusión: no realizar seguimiento por la sanidad pública. Mediciones principales Variables demográficas, variables clínicas (fármacos, diagnóstico de anemia, paciente crónico complejo o enfermedad crónica avanzada. Variables consumo de recursos (número de visitas a atención primaria, número de ingresos hospitalarios y número de consultas a urgencias). Las variables demográficas y clínicas se evaluaron mediante frecuencias y porcentajes, media y desviación estándar para las variables cuantitativas. Las características de los diferentes subgrupos se compararon con la t de Student. Resultados La prevalencia de la anemia fue del 3,78%. Media de edad 64,5 años, el 60,8% mujeres. El 15,8% identificados como pacientes crónicos complejos. La hipertensión arterial presente en el 51,46%. El 50,97% fueron anemias ferropénicas. Consultaron al médico de familia 2,25 veces de media y a la enfermera de familia 1,49 veces. De las personas con criterios analíticos de anemia, solo el 46,57% tenían registrado un diagnóstico de anemia. Conclusiones En el territorio estudiado se ha objetivado un infraregistro del diagnóstico de anemia. Se observan diferencias en la caracterización por género y edad (AU)

Objective To determine the prevalence of anemia and the defining characteristics of the individuals who suffer from it. Design Population-based descriptive observational study. Variables extracted from the computerized database of primary care medical records. Setting This study was conducted in the Metropolitana Nord health region, Barcelona. Participants Patients with anemia evaluated by hemoglobin, during the year 2019. Inclusion criteria: older than 14 years, with hemoglobin determinations below the value recommended by the WHO. Exclusion criteria: no follow-up by public health. Main measurements Demographic variables, clinical variables (drugs, diagnosis of anemia, complex chronic patient or advanced chronic disease. Resource consumption variables (number of visits to primary care, number of hospital admissions, and number of visits to the emergency room). The variables demographic and clinical variables were evaluated using frequencies and percentages, mean and standard deviation for quantitative variables. The characteristics of the different subgroups were compared with Student's t-test. Results The prevalence of anemia was 3.78%. Mean age 64.5 years and 60.8% women. 15.8% identified as complex chronic patients. Arterial hypertension present in 51.46%. 50.97 were iron deficiency anemias. They consulted the family doctor 2.25 times on average and the family nurse 1.49. Of the people with analytical criteria for anemia, only 46.57 had a registered diagnosis of anemia. Conclusions In the territory studied, an under-reporting of the diagnosis of anemia has been observed. Differences are observed in the characterization by gender and age (AU)
