Regional inequalities of hospital morbidity and associations with mortality in Lithuania

Background and objective: In Lithuania, hospitalization was planned to be reduced with the approval of the national healthcare restructuring program. The aim of this study was to describe regional inequalities of hospitalization and hospital morbidity in Lithuania and to associate them with mortality in the regions.

Materials and methods: Routine hospital discharge data of Lithuanian hospitals, reimbursed by the Compulsory Health Insurance Fund and registered in database SVEIDRA, was used. Age-adjusted general hospitalization and hospital morbidity rates (per 1000 population) due to cardiovascular diseases (CVD), malignant neoplasms and external causes were calculated. Contribution of diseases, causing major public health problems, to general hospitalization was evaluated by analysis of components. Association of general hospitalization or hospital morbidity and mortality of respective causes was evaluated using non-parametric Spearman correlation.

Results: General hospitalization and hospital morbidity of CVD, malignant neoplasms and external causes had increased from 2005 to 2011. Inequalities of hospitalization and hospital morbidity existed between regions of Lithuania. In Šiauliai, Klaipėda, Utena and Panevėžys regions, general hospitalization remained higher than national level. In Marijampolė, Alytus and Kaunas regions, general hospitalization became lower than Lithuanian average. There was no statistically significant correlation between variation in hospitalization and mortality rates in the regions.

Conclusions: Despite national efforts to decrease hospital care, our study detected the failure of hospitalization reduction and revealed an increase of hospitalization with the existing regional inequalities in Lithuania.
