[Predictive factors of all-cause mortality in patients attending the medical emergency unit of Kinshasa University Hospital].
The management of medical emergencies is poorly organized in the Democratic Republic of Congo. In addition, the mortality of patients attending the medical emergency unit of Kinshasa University Hospital is relatively high, with death of patients occurring rather early. To date, factors associated with this mortality have been poorly elucidated. This study aimed to identify predictive factors of all-cause mortality in patients admitted to the medical emergency unit of the Kinshasa University Hospital. ⋯ Our study showed that transfer from another health care structure, low Glasgow Coma Scale score on admission, high creatinine level, cardiovascular, renal, hematologic and/or respiratory diseases, sepsis and/or meningitis and encephalitis were associated with an increased risk of death in Kinshasa University Hospital patients admitted in the medical emergency unit.

Epidemiological research is mostly based on observational studies. Whether such studies can provide evidence of causation remains discussed. Several causal analysis methods have been developed in epidemiology. ⋯ In conclusion, "causal models", though they were developed partly independently, are based on equivalent logical foundations. A crucial step in the application of these models is the formulation of causal hypotheses, which will be a basis for all methodological choices. Beyond this step, statistical analysis tools recently developed offer new possibilities to delineate complex relationships, in particular in life course epidemiology.
