Patients admitted to an intensive care unit who do not adopt an antigravity posture have a higher odds of death
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
ABSTRACT Until now, few functional performance markers are able to predict death in Intensive Care Units (ICUs). This study aimed to identify the association between non-adoption of antigravity posture and death in patients admitted to an adult ICU. It is a retrospective and analytical study, performed through the analysis of medical records. Association between non-adoption of antigravity posture and death was tested by multiple logistic regression adjusted for gender, age, disease severity (measured by Acute Physiology and Chronic Health Classification System II [Apache II]), time of invasive mechanical ventilation (IMV), and period of sedation. The odds ratio (OR) with confidence interval (CI=95%) was estimated. A total of 92 sequential patients were included in the study. A strong association between the non-adoption of antigravity posture in the ICU and death (ORadjusted=37.7, CI=4.76-293, p=0.001) was observed. Thus, one can conclude that patients who did not adopt an antigravity posture during ICU admission had a much higher odds of mortality. This simple strategy to classify functional capacity of critical patients can be routinely used by the team as a simple and dichotomous variable for ICU mortality prognosis.
