Abstract

Objective

To determine the internal consistency (IC), minimal detectable change (MDC), and sensitivity to change of the Barthel Index (BI) at ICU discharge and three months post-hospital discharge.

Methods

A prospective longitudinal study was conducted between November 2016 and July 2017 in a medical-surgical intensive care unit (ICU). A total of 149 patients over 18 years with a BI score >90 prior to ICU admission were included. The COSMIN checklist was utilized to evaluate the measurement properties. Clinical and demographic variables, BI scores, IC, MDC, and sensitivity to change were analyzed. The Cronbach's alpha coefficient (α) was calculated to determine the IC of the BI by domain and for the overall scale. Effect size (ES) indices and standardized mean response (SMR) were used for sensitivity to change. The MDC was identified using a distribution-based method, calculating the standard error of measurement (SEM). Floor and ceiling effects were assessed, with a threshold of less than 15% considered acceptable.

Results

A total of 141 patients were evaluated at discharge from the ICU. Of these, n = 77 (41.7%) were men, with a mean age of 58.5 ± 16.8 years; n = 62 (41.6%) required invasive mechanical ventilation. One hundred twelve patients were reassessed three months after discharge. The overall IC was: α = 0.70 at ICU discharge and α = 0.96 at three months. Ninety two percent (n = 103) of the patients showed values greater than or equal to the MDC of 10 points, with statistically significant differences identified in the type of weaning, tracheostomy, and length of stay in the ICU (p < 0.005).

Conclusions

The items of the Spanish version of the BI demonstrate acceptable IC at ICU discharge. The MDC was 10 points, validating its responsiveness and utility for monitoring the functional independence of critically ill patients at ICU discharge and three months after hospital discharge.
