Objective:

To evaluate the incidence of postoperative delirium in the Intensive Care Unit of the Angeles Pedregal Hospital, as well as identify the risk factors and prognosis of patients with postoperative delirium.

Material and methods:

Frequency analysis study in the period from January 1, 2018 to December 31, 2019. For statistical analysis, measures of central tendency and dispersion were used. The presence of risk factors for delirium was sought by relative risk with 95% CI. For the statistical associations, the χ2 and Mann-Whitney U tests were used as required. p < 0.05 was considered statistically significant.

Results and conclusions:

Our sample was consisted of 84 patients. The incidence of postoperative delirium at the UTI-HAP was 21.4%. The presence of mechanical ventilation was statistically associated (χ2: 21.212, p = 0.00) with the presence of delirium (relative risk 16.46; 95% CI 4.72-57.3). There was a statistically significant difference between postoperative delirium and days of stay in the Intensive Care Unit (U Mann-Whitney 166; p = 0.000).
