Specificity and sensibility of the Spanish version of the COMFORT Behaviour Scale for assessing pain, grade of sedation and withdrawal syndrome in the critically ill paediatric patient. Multicentre COSAIP study (Phase 1).

AIM: The main aim of this investigation was to analyse the specificity and sensibility of the COMFORT Behaviour Scale (CBS-S) in assessing grade of pain, sedation, and withdrawal syndrome in paediatric critical care patients. METHOD: An observational, analytical, cross-sectional and multicentre study conducted in Level III Intensive Care Areas of 5 children's university hospitals. Grade of sedation was assessed using the Spanish version of the CBS-S and the Bispectral Index on sedation, once per shift over one day. Grade of withdrawal was determined using the CBS-S and the Withdrawal Assessment Tool-1, once per shift over three days. RESULTS: A total of 261 critically ill paediatric patients with a median age of 5.07 years (P25:0.9-P75:11.7) were included in this study. In terms of the predictive capacity of the CBS-S, it obtained a Receiver Operation Curve of .84 (sensitivity of 81% and specificity of 76%) in relation to pain; .62 (sensitivity of 21% and specificity of 78%) in relation to sedation grade, and .73% (sensitivity of 40% and specificity of 74%) in determining withdrawal syndrome. CONCLUSIONS: The Spanish version of the COMFORT Behaviour Scale could be a useful, sensible and easy scale to assess the degree of pain, sedation and pharmacological withdrawal of critically ill paediatric patients.
