Introduction:

The shock index has been proposed as an effective, cheap and easily achievable parameter for the prognosis of possible complications and even death.

Objective:

To describe the shock index values in patients admitted to Intensive Care Unit at the Hospital General Docente “Vladimir Ilich Lenin” de Holguín, Cuba, throughout June to December 2019.

Method:

A descriptive cross-sectional study was performed in which 98 patients (N=98) admitted to ICU were selected as universe, the sample consisted of 77 patients (n=77) through non-probabilistic sampling. Variables evaluated were as follow: APACHE II system, shock index, presumptive etiologic diagnosis, qSOFA score and serum lactate level. A data collection form was used as a research instrument. The SPSS version 24 statistical package was used. The mean and standard deviation were used to process the quantitative variables.

Results:

The predominant diseases found were postpartum hemorrhage, the postoperative complication and pre-eclampsia disorder. Serum lactate values were normal in 54.5% of studied patients and normal or low qSOFA values in 59.7%. The 84.2% showed low APACHE II values on admission and 58.5% had a shock index greater than 0.7.

Conclusions:

Patients admitted to the ICU show greater alterations in the shock index than in better known and widely used variables like (APACHE II, qSOFA and serum lactate).
