RESUMO
BACKGROUND: Critical care nurses must assess the effectiveness of sedatives and analgesic agents in order to titrate doses. OBJECTIVES: To measure the interrater reliability of 2 sedation scales used to assess patients in medical intensive care units. METHODS: The interrater reliabilities of the Motor Activity Assessment Scale and the Luer sedation scale were compared prospectively in 31 patients receiving mechanical ventilation in an 18-bed medical intensive care unit of a tertiary care institution. Three registered nurses, 1 clinical pharmacist, and 1 physician simultaneously and independently followed a standardized procedure to rate each patient by using the 2 scales. Scales were randomly ordered to counteract ordering effect. Analysis of variance with post hoc Duncan multiple range tests was used to detect bias; a correlation coefficient matrix was used to examine degree of association among raters; and the intraclass correlation coefficient was measured to control for multiple raters. RESULTS: No significant bias was detected with either scale. The Motor Activity Assessment Scale had less variation (Pearson r = 0.75-0.92) than did the Luer scale (Pearson r = 0.37-0.94) and had a stronger intraclass correlation coefficient (0.81 vs 0.79). CONCLUSIONS: The Motor Activity Assessment Scale showed the highest consistency among raters.

Venous thromboembolic disease has emerged as a significant cause of morbidity and mortality in hospitalized patients. This article reviews the salient features of venous thromboembolism as they pertain to the critically ill. Emphasis is placed on identifying risk factors, diagnostic strategies, prophylaxis, and treatment of this disorder. Deep venous thrombosis and pulmonary embolism, both being manifestations of the same disease processes, are considered together in this discussion of venous thromboembolism.
