Behavior of the functional independence domains in patients submitted to the revascularization of the myocardium during intensive care unit stay

Abstract

INTRODUCTION: Functional Independence Measurement (MIF) is used to evaluate the functional status of patients being divided into domains and should be applied in patients undergoing cardiac surgery due to their high potential for deleterious effects. OBJECTIVE: To analyze the behavior of MIF domains in patients submitted to myocardial revascularization. MATERIALS AND METHODS: This is a cohort study. At the time of hospital admission, the functionality was evaluated through the MIF and computed the six domains. After the surgery on the day of discharge from the Intensive Care Unit (ICU), the MIF was again applied for comparison with the preoperative period and correlation with the length of stay in the ICU. RESULTS: A total of 38 patients were analyzed: 21 (55.3%) men, mean age was 57.3 ± 13.3 years. The mean ICU stay was 2.9 ± 1.3 days, with a FIM of 125.7 ± 0.5 and a mean of 87.4 ± 16.8 (p <0.001). In relation to the domains, a reduction was observed in all of them, with the exception of Communication from 14 to 13.1 ± 2.1 (p = 0.24) and Cognition 20.9 ± 0.1 to 19.2 ± 4, 4 (p = 0.24). However, there was a strong correlation between ICU stay time with the communication domains (r -0.76 and p <0.01) and cognition (r -0.77 and p <0.01). CONCLUSION: It is concluded that the functionality is reduced due to cardiac surgery and that the time spent in the ICU is directly related to the worsening of communication and cognition.
