Patterns of Medical Admissions and Predictors of Mortality in Ayder Comprehensive Specialized Hospital, Northern Ethiopia: A Prospective Observational Study

Previous works show that noncommunicable diseases (NCDs) are on the rise in developing nations, including Ethiopia, in the background of preexisting communicable diseases (CDs). Data on hospital admission in sub-Saharan Africa are scarce, particularly prospectively collected, and hence this study was done to close the gap in acquiring accurate diagnosis usually faced with retrospective data. We aimed to describe medical admission patterns, their outcomes and determinants at Ayder Comprehensive Specialized Hospital (ACSH) in Tigray, Ethiopia. Data were collected prospectively from November 1, 2017 to October 31, 2018 for all medical admissions. Sociodemographic profiles, final diagnosis, outcome of hospitalization, and complications were recorded using a data-abstraction checklist. Data were analyzed using SPSS 26. There were 2084 medical admissions over 1 year. Median age was 45 years (IQR 31). A majority (1107, 53.1%) were male. The age-group 25-34 years had the most admissions (19.0%). NCDs constituted 68.2% of admissions. According to the , patients were admitted most frequently due to disease of the circulatory system (36.7%) followed by infectious or parasitic diseases (24.1%). Of NCDs, cardiovascular diseases contributed to 53.9%, followed by cancers (8.6%). Of CDs, HIV/AIDS contributed to 31.3%, followed by tuberculosis (22.8%). A total of 1375 (66%) were discharged improved, while 311 (14.9%) died. On multivariate analysis, the in-hospital mortality was significantly higher (18.7%) for CDs than NCDs (13.2%, AOR 1.8, 95% CI 1.4-2.3;
