The Neonatal Pain, Agitation and Sedation Scale and the bedside nurse's assessment of neonates.

Abstract

To determine the reliability of an objective measure of pain, agitation and sedation using the Neonatal Pain, Agitation and Sedation Scale (N-PASS) compared with nursing bedside assessment. Neonates admitted in neonatal intensive care unit over a 6-month period were eligible. Pain and sedation were assessed with N-PASS, and a subjective questionnaire was administered to the bedside nurse. A total of 218 neonates were eligible (median: gestational age 34.6 weeks, age at assessment 7 days). N-PASS pain score correlated significantly with both nurses' pain score (Spearman coefficient (r)=0.37; P<0.001) and agitation score (r=0.56; P<0.001). N-PASS sedation score correlated with nurses' sedation score (r=-0.39; P<0.001). Adjusting for gestational age, day of life, intrauterine drug exposure and use of high frequency ventilation only slightly attenuated the correlations (r=0.36, 0.55 and -0.31, respectively). The N-PASS captures nursing assessment of pain, agitation and sedation in this broad population and provides a quantitative assessment of subjective descriptions that often drives patient therapy.
