METHODS: Clinical conditions and weights were adapted from the International Classifi cation of Diseases, 10th revision and applied to a single hospital admission diagnosis. The study included 3,733 patients over 18 years of age who were admitted to a public general hospital in the city of Rio de Janeiro, southeast Brazil, between Jan 2001 and Jan 2003. The index distribution was analyzed by gender, type of admission, blood transfusion, intensive care unit admission, age and length of hospital stay. Two logistic regression models were developed to predict in-hospital mortality including: a) the aforementioned variables and the risk-adjustment index (full model); and b) the risk-adjustment index and patient’s age (reduced model). RESULTS: Of all patients analyzed, 22.3% had risk scores ≥1, and their mortality rate was 4.5% (66.0% of them had scores ≥1). Except for gender and type of admission, all variables were retained in the logistic regression. The models including the developed risk index had an area under the receiver operating characteristic curve of 0.86 (full model), and 0.76 (reduced model). Each unit increase in the risk score was associated with nearly 50% increase in the odds of in-hospital death. CONCLUSIONS: The risk index developed was able to effectively discriminate the odds of in-hospital death which can be useful when limited information is available from hospital databases. 2008 artículo científico 0034-8910 https://www.redalyc.org/articulo.oa?id=67240169003 en http://www.redalyc.org/revista.oa?id=672 Revista de Saúde Pública application/pdf Universidade de São Paulo Revista de Saúde Pública (Brasil) Num.4 Vol.42 |
