Insights
This study identified key factors predicting mortality in hospitalized Acquired Immunodeficiency Syndrome (AIDS) patients in São Paulo. Prognostic variables like age and specific infections significantly influenced survival rates during hospitalization.
Area of Science:
- * Clinical Medicine
- * Epidemiology
- * Infectious Diseases
Background:
- * Hospitalized patients with Acquired Immunodeficiency Syndrome (AIDS) require accurate prognostic indicators for effective management.
- * Understanding factors associated with in-hospital mortality is crucial for improving patient outcomes in diverse settings.
Purpose of the Study:
- * To investigate survival rates and identify prognostic variables for in-hospital death among Acquired Immunodeficiency Syndrome (AIDS) patients.
- * To utilize discriminant analysis for exploratory data analysis to guide survival analysis.
Main Methods:
- * A cohort of 312 Acquired Immunodeficiency Syndrome (AIDS) patients in São Paulo were studied.
- * Discriminant analysis was employed for exploratory data analysis to identify key prognostic variables.
- * Survival analysis was conducted based on the findings from the discriminant analysis.
Main Results:
- * Nine variables were identified as significant predictors of mortality during hospitalization.
- * Key prognostic factors included age, disease duration, gender, helminthic infections, number of risk groups, fungal infections, transfusion history, esophageal candidiasis, and Cryptosporidium sp. infection.
- * The identified variables offer insights into the progression of Acquired Immunodeficiency Syndrome (AIDS) and associated mortality risks.
Conclusions:
- * Discriminant analysis effectively identified significant prognostic variables for in-hospital death in Acquired Immunodeficiency Syndrome (AIDS) patients.
- * The findings provide valuable information for future research on predicting mortality in hospitalized Acquired Immunodeficiency Syndrome (AIDS) patients, particularly in resource-limited settings.
- * While some variables' importance may vary geographically, they highlight critical aspects of disease progression and patient vulnerability.
Abstract:
We studied the survival rates and the prognostic variables that corresponded to death during hospitalization in 312 AIDS CDC group IV patients in São Paulo. Discriminant analysis proved to be a good tool to perform the exploratory data analysis that guided the survival analysis groups. It selected nine variables that were important in the progress of the disease: age, time elapsed from the first manifestations of the disease, gender, infection by helminths, number of risk groups to which the patient belonged, number of infections by fungi, history of transfusion, presence of esophageal candidiasis, and infection by Cryptosporidium sp. Although some of these variables may be of limited importance in developed countries, and some variables that we expected to be important were not present in the final discriminant function, we believe these results may guide future research in prognosis of death in hospitalized AIDS patients.
