Introduction:

in the intensive care unit of the General Teaching Hospital "Dr. Agostinho Neto" the influence of the seasons of the year on the profile of morbidity and mortality has not been clarified.

Objective:

to determine the influence of the variability of season of the year on the morbidity and mortality profile of the ICU of the General Teaching Hospital "Dr. Agostinho Neto" during the year 2018.

Method:

a retrospective study was made of the total number of admitted patients (n = 549) and a random sample of 365 patients was selected. The variables studied were: age, sex, reason for admission, severity index, stay in the unit, need for mechanical ventilation, discharge status. All were related to the weather.

Results:

the largest number of patients admitted during the summer (31.8%). There was no significant relationship between the weather station and the sex variable (p <0.05), but with age, APACHE II, stay in the unit and need for mechanical ventilation (p <0.05). In spring and summer the most common disease was cerebrovascular, while in autumn and winter the most common was community-acquired severe pneumonia. The variables stay in the unit, patient entry for diseases of a clinical nature according to the type of clinical patient and mortality were significantly related to the weather station (p <0.05).

Conclusions:

the climatic variability of the Guantanamo context influenced the morbidity profile of the intensive care unit and measured the prognosis of patients admitted with critical illness.
