[Health services' utilization patterns in Catalonia, Spain].

The purpose of this article is disclose services utilization patterns among the Catalan population with particular emphasis on primary care, specialised care, hospital care and emergency care. A number of logistic regression models were used to explain the utilization of the various types of services. Variables in the analysis included self-perceived need, lifestyles, and sociodemographic variables. Separate analyses were performed for male, female, adults, and children as well as for the general population. Women use all types of services more often than men. Children and people over 64 are more frequent users of primary care. Primary care is also associated to lower socioeconomic conditions. Young adults and the migrant population in general are found to be under users of services, except of emergency care services. The use of specialised care is associated to the better-off, to those with university level education attainment, individual private insurance, and those living in the city of Barcelona. Hospital care is largely associated to need variables. The use of health services is explained by self-perceived need as well as by demographic, socioeconomic and geographical factors.
