Abstract
Introduction

To compare the inter-practice variability in lipid metabolism laboratory tests requested by General Practitioners in Spain using appropriateness indicators and investigate the variability according to the different characteristics of the geographical regions.

Materials and methods

141 clinical laboratories were invited to participate from diverse regions across Spain. We obtained the number of serum cholesterol, high-density cholesterol (HDL-cholesterol) and triglycerides requested by General Practitioners for the year 2012. Two types of appropriateness indicators were calculated: test requests per 1000 inhabitants and ratio of related tests requests (HDL-cholesterol/cholesterol, triglycerides /cholesterol). The indicators results obtained in different setting, with different type of management and in different geographical areas were compared.

Results

We obtained production statistics from 76 laboratories who attended a population of 17,679,195 inhabitants from 13 Communities throughout Spain. 5,823,053 cholesterol, 4,544,663 HDL-cholesterol and 5,599,358 triglycerides tests were ordered. Cholesterol, HDL-cholesterol and triglycerides per 1000 inhabitants indicators results ranged from 106.3 to 550.7; 20.4 to 417.5 and from 94.0 to 439.2 respectively. HDL-cholesterol/cholesterol, triglycerides/cholesterol indicators results ranged from 0.19 to 1.00 and from 0.54 to 1.00 respectively. Cholesterol, HDL-cholesterol and triglycerides were higher requested in rural areas. No significant differences in tests requests were observed based on Spanish Community.

Conclusion

There was a high variability in cholesterol, triglycerides and HDL-cholesterol requesting in primary care in Spain. Cholesterol was probably inappropriately under requested to screen for hypercholesterolemia in certain areas that would suggests a potential risk for inappropriate dyslipidemia screening in general population, emphasizing the need to establish interventions.

Resumen
Introducción

Estudiar la solicitud de pruebas de laboratorio relacionadas con el metabolismo lipídico desde atención primaria para averiguar la variabilidad en su demanda y su relación con las diferentes características de las áreas.

Material y métodos

Se invitó a participar a 141 laboratorios de distintas regiones. Se requería que remitieran el número de pruebas de colesterol, colesterol HDL (cHDL) y triglicéridos solicitadas desde atención primaria en el año 2012. Se calculó la solicitud anual por 1.000 habitantes y el ratio de solicitud de 2 pruebas relacionadas.

Resultados

Se recibió la estadística de 76 laboratorios que atendían a una población de 17.679.195 habitantes y pertenecían a 13 comunidades españolas. En total, se solicitaron 5.823.053 pruebas de colesterol, 4.544.663 de cHDL y 5.599.358 de triglicéridos. El número de pruebas de colesterol, cHDL y triglicéridos solicitados por 1.000 habitantes fue de 106,3 a 550,7, de 20,4 a 417,5 y de 94,0 a 439,2, respectivamente. El ratio de solicitudes de cHDL/colesterol y triglicéridos/colesterol fue de 0,19 a 1,00 y de 0,54 a 1,00, respectivamente. El colesterol, el cHDL y los triglicéridos fueron más solicitados en áreas rurales que en urbanas o rurales/urbanas. No se observaron diferencias relacionadas con la comunidad autónoma.

Conclusión

Existió una gran variabilidad en la solicitud desde atención primaria de colesterol, cHDL y triglicéridos El colesterol en determinadas áreas es probable que fuera inadecuadamente solicitado por defecto, lo que sugiere un potencial riesgo de inadecuado cribado de dislipidemia en la población general e indica la necesidad de diseñar y establecer medidas correctoras.
