Psychometric validation of the behavioral indicators of pain scale for the assessment of pain in mechanically ventilated and unable to self-report critical care patients / Validación psicométrica de la Escala de Conductas Indicadoras de Dolor para la medición de dolor en pacientes críticos, no comunicativos y sometidos a ventilación mecánica

OBJECTIVE: To assess the psychometric properties of the behavioral indicators of pain scale (ESCID) when applied to a wide range of medical and surgical critical patients. DESIGN: A multicentre, prospective observational study was designed to validate a scale measuring instrument. SETTING: Twenty Intensive Care Units of 14 hospitals belonging to the Spanish National Health System. PARTICIPANTS: A total of 286 mechanically ventilated, unable to self-report critically ill medical and surgical adult patients. Procedure: Pain levels were measured by two independent evaluators simultaneously, using two scales: ESCID and the behavioral pain scale (BPS). Pain was observed before, during, and after two painful procedures (turning, tracheal suctioning) and one non-painful procedure. MAIN VARIABLES: ESCID reliability was measured on the basis of internal consistency using the Cronbach-_ coefficient. Inter-rater and intra-rater agreement were measured. The Spearman correlation coefficient was used to assess the correlation between ESCID and BPS. RESULTS: A total of 4386 observations were made in 286 patients (62% medical and 38% surgical). High correlation was found between ESCID and BPS (r=0.94-0.99; p < 0.001), together with high intra-rater and inter-rater concordance. ESCID was internally reliable, with a Cronbach-_ value of 0.85 (95%CI 0.81-0.88). Cronbach-_ coefficients for ESCID domains were high: facial expression 0.87 (95%CI 0.84-0.89), calmness 0.84 (95%CI 0.81-0.87), muscle tone 0.80 (95%CI 0.75-0.84), compliance with mechanical ventilation 0.70 (95%CI 0.63-0.75) and consolability 0.85 (95%CI 0.81-0.88). CONCLUSION: ESCID is valid and reliable for measuring pain in mechanically ventilated unable to self-report medical and surgical critical care patients

OBJETIVO: Evaluar las propiedades psicométricas de la Escala de Conductas Indicadoras de Dolor (ESCID), aplicada a una muestra amplia de pacientes críticos de patología médica y posquirúrgica. DISEÑO: Estudio multicéntrico, observacional, prospectivo de validación de una escala como instrumento de medida. Ámbito: Veinte Unidades de Cuidados Intensivos de 14 hospitales del Sistema Nacional de Salud español. PARTICIPANTES: Doscientos ochenta y seis pacientes críticos adultos, sometidos a ventilación mecánica, sin capacidad de comunicación, de patología médica y posquirúrgica. Intervención: Se midió el nivel de dolor de los pacientes por 2 observadores de manera simultánea y utilizando dos escalas: ESCID y la Behavoiral Pain Scale. El dolor fue medido antes, durante y después de la aplicación de dos procedimientos dolorosos (movilización y aspiración endotraqueal) y un procedimiento no doloroso. Variables de interés: La fiabilidad de ESCID se midió mediante la consistencia interna determinada con el coeficiente alfa de Cronbach. Se midió la concordancia inter- e intraobservadores. Se determinó la correlación entre las escalas ESCID y Behavoiral Pain Scale mediante el coeficiente de Spearman. RESULTADOS: Se realizaron 4.386 observaciones de dolor en 286 pacientes (62% patología médica y 38% posquirúrgica). Se evidencia una alta correlación entre ESCID y Behavoiral Pain Scale(r = 0,94-0,99; p < 0,001) así como una alta concordancia inter- e intraobservador. La escala ESCID presenta buena consistencia interna, con un valor de α-Cronbach de 0,85 (IC 95% 0,81-0,88). Los 5 dominios de ESCID presentan alta consistencia interna con α-Cronbach: musculatura facial 0,87 (IC 95% 0,84-0,89), tranquilidad 0,84 (IC 95% 0,81-0,87), tono muscular 0,80 (IC 95% 0,75-0,84), adaptación a ventilación mecánica 0,70 (IC 95% 0,63-0,75) y confortabilidad 0,85 (IC 95% 0,81-0,88). CONCLUSIÓN: ESCID es válida y fiable para medir el dolor en pacientes críticos médicos y posquirúrgicos, no comunicativos y sometidos a ventilación mecánica

Valoración del dolor durante el postoperatorio inmediato de cirugía cardiaca mediante la Behavioural Pain Scale / Evaluation of immediate post-operative pain in heart surgery using the Behavioural Pain Scale

INTRODUCCIÓN: Los pacientes en el postoperatorio inmediato de cirugía cardiaca tienen la capacidad de comunicación abolida, y por tanto no pueden expresar dolor. El dolor produce importantes efectos adversos que alteran la evolución de los pacientes, por lo que su identificación y control suponen un aumento de la calidad de atención al paciente crítico. OBJETIVO: Medir el grado de dolor en los pacientes en el postoperatorio inmediato de cirugía cardiaca mediante la Behavioural Pain Scale. MATERIAL Y MÉTODO: Estudio observacional, prospectivo y longitudinal. Se incluyeron pacientes mayores de 18 años, sin problemas de comunicación y que se encontraban bajo sedación y sometidos a ventilación mecánica. Se incluyeron en el estudio 20 pacientes. Se utilizó la Behavioural Pain Scale (BPS) durante la realización de 2 procedimientos de la práctica habitual considerados en la literatura como dolorosos: la movilización y/o cambio postural y la aspiración de secreciones. RESULTADOS: Se realizaron 27 mediciones de procedimientos considerados como dolorosos. Los resultados obtenidos al aplicar la BPS fueron que el 70,4% de los pacientes tuvieron ausencia de dolor. El 22,2% de los pacientes tuvieron dolor leve-moderado y el 7,4% tuvieron un dolor inaceptable. CONCLUSIÓN: En este estudio se ha identificado que los pacientes sufren dolor durante el postoperatorio inmediato y que de ellos existe un pequeño porcentaje, pero no por eso despreciable, que sufre dolor inaceptable durante este período. Esto es un hallazgo que sirve como inicio de una línea de investigación para mejorar el manejo del dolor durante el postoperatorio inmediato de cirugía cardiaca

INTRODUCTION: Patients in the immediate postoperative period of cardiac surgery have abolished communication skills and therefore can not express pain. Pain produces significant adverse effects that alter the patients' course. Therefore, identifying and controlling them will lead to increased quality of care for the critical patient. OBJECTIVE: To measure the degree of pain in patients in the immediate postoperative period of cardiac surgery by scaling Behavioural Pain Scale. MATERIAL AND METHOD: An observational, prospective and longitudinal. Patients over 18 years in the first 24 hours of admission with no communication problems who were under sedation and subjected to mechanical ventilation were included. Twenty patients were enrolled in the study. The Behavioural Pain Scale (BPS) was used during two procedures usually considered as a painful practice in the literature, that is, mobilization and/or postural changes and aspiration of secretions. RESULTS: Twenty-seven measurements were made of procedures considered as painful. The results obtained by applying the scale BPS showed that 70.4% of patients had no pain, 22.2%had mild to moderate pain and 7.4% had unacceptable pain. CONCLUSION: This study has identified that the patients suffer pain during the postoperative period. Within these patients, there is a small, but not insignificant number whose pain is unacceptable during this period. This finding serves as a beginning for a line of research to improve the handling of the postoperative pain during immediate post-operative cardiac surgery
