[Unnecessary premature and avoidable mortality in Costa Rica]

With the intention of establishing economic inequities, the article analyzes the variations of the Unnecessarily Premature and Sanitarily Avoidable Mortality (MIPSE) of each of the 81 cantons of Costa Rica during 2000-2005. It is important to identify those inequities, to establish policies and strategies trying to mitigate them.

It applies the MIPSE classification proposed by members of the Information and Studies Service, of the Catalunya's Sanitary Resources Headquarter, Spain. By an Indicator of Socioeconomic Development (IDSE) of a University of Costa Rica economist's team, it organised each canton in groups of quintiles (I for the richest, V for the poorest), previous people standardization.

We found as a major causes of mortality MIPSE in the country: Heart Isquemic Disease (19,55% MIPSE causes), Traffic Accidents with Motor Vehicles (11,60%), Brain Vascular Disease (6,95%), Perinatal (6,92%) and Suicide (5,14%).

The VIH infection - AIDS mortality, the Best Cancer in Women, Uterus Cancer, Skin Cancer and Hepatic Disease Secondary to Alcohol Consumption, affects more the cantons with better financial conditions and the Prostate Benign Hyperplasia mortality, Mothers mortality related with Pregnancy, Childbirth or Puerperal Stage and the Abdominal Hernia mortality, affects more to those with worst economic level. Two MIPSE groups were identified with similar inequality: Leukaemia and Congenital Cardiovascular Disease.
