[Predictive factors of mortality in intensive care at the Hospital Principal of Dakar / Senegal].

OBJECTIVES

To analyze the main causes and risk factors of death in intensive care.

PATIENTS AND METHOD

Prospective observational study in the intensive care units in Hospital Principal of Dakar from July to December 2018 including all patients who died 24 hours after admission. Demographic, clinical, severity (IGSII, APACHE II, MPM) and organ failure (SOFA, LODS) scores were collected. A multiparametric comparison was made between deceased and surviving patients.

RESULTS

The overall mortality was 25.86% correlated with the probability of death (MPM): 26.4%. The mean age was 50.98 [8-94 years] with a sex ratio of 1.15. The majority of deaths (79.26%) occurred outside of duty hours and 70.7% had at least one medical history. The mean severity scores were for IGSII 40.12 +/- 17.25 and for APACHE II 18.31 +/- 8.49. The mean visceral failure scores were for SOFA 7.02 +/- 4.44 and for LODS 5.73 +/- 3.35. Complications were dominated by nosocomial infections (48.78%) and are responsible for 37.8% of deaths. The mean length of stay was 7.30 days +/- 7.46. Age, the existence of organ failure, the use of vasopressors, the occurrence of nosocomial infections and the absence of a senior doctor were correlated with mortality.

CONCLUSION

The intensive care unit mortality rate is 25.86%. Advanced age, the existence of organ failures and the occurrence of a nosocomial infection are factors in the occurrence of death.
