[Validity of predictive power of the Adjusted Morbidity Groups (AMG) with respect to others population stratification tools.].

Objective: This work was performed in order to get objective elements of judgment that support the improvement of a national population morbidity grouper based in the Adjusted Morbidity Groups (AMG). The study compared the performance in terms of predictive power on certain health and resource outcomes, in between the AMG and several existing morbidity groupers (ACG®, Adjusted Clinical Groups and CRG®, Clinical Risk Group) used in some Autonomous Regions in Spain (Aragón, Canarias y Castilla y León).

Methods: Cross-sectional analytical study in entitled/insured population with respect to rights of healthcare.

[Descriptive epidemiology of non-meningococcal bacterial meningitis in the province of Saragossa [Spain] from 1999 to 2004. Evaluation of the Epidemiological Surveillance System].

Objectives: To describe non-meningococcal bacterial meningitis (nMM) and to evaluate the Epidemiological Surveillance System (ESS) in the province of Saragossa (Spain) between 1999 and 2004.

Methods: Information was obtained from the register of diseases subject to mandatory reporting and the Minimum Basic Data Set (MBDS). The ESS was evaluated by using the Centers for Disease Control and Prevention (CDC) criteria and by estimating the completeness of the system through the capture-recapture technique.
