ABSTRACT
OBJECTIVES: Limited data exist regarding clinical outcomes of invasive methicillin-resistant Staphylococcus aureus (MRSA) infections in children treated with vancomycin. Treatment success in adults correlates best with an area under the curve/minimum inhibitory concentration (AUC24/MIC) ratio ≥400. It is unknown if this relationship is useful in children. METHODS: Charts of children who received vancomycin ≥5 days for MRSA bacteremia with a steady state trough were reviewed. AUC24/MIC ratios were estimated using 2 different vancomycin clearance equations. Vancomycin treatment failure was defined as persistent bacteremia ≥7 days, recurrent bacteremia within 30 days, or 30-day mortality. RESULTS: There were 67 bacteremia episodes in 65 patients. Nine (13.4%) met failure criteria: persistent bacteremia (n = 6), recurrent bacteremia (n = 2), 30-day mortality (n = 1). There were no differences between patients receiving <60 mg/kg/day and ≥60 mg/kg/day of vancomycin in median trough (11.9 versus 12.3 mg/L, p = 0.1). Troughs did not correlate well with AUC24/MIC ratios (R 2 = 0.32 and 0.22). Patients receiving ≥60 mg/kg/day had greater probability of achieving ratios ≥400. There were no significant differences in median dose (p = 0.8), trough (p = 0.24), or AUC24/MIC ratios (p = 0.07 and p = 0.6) between patients with treatment success and failure. CONCLUSIONS: Treatment failure was lower than previously reported in children. AUC24/MIC ratios ≥400 were frequently achieved but were not associated with treatment success, dose, or troughs. Prospective studies using standard definitions of vancomycin treatment failure are needed to understand treatment failure in children with MRSA bacteremia.
ABSTRACT
INTRODUCTION: Pain management is a critical aspect of effective long bone fracture treatment. Pediatric patients frequently report suboptimal pain management, which is an area of growing public concern. The purpose of this quality improvement project was to develop a protocol with the goal to administer pain medication to children presenting with suspected long bone fractures ≤47 minutes of emergency department arrival. METHODS: A multidisciplinary team developed a standardized protocol for pain management of patients presenting with musculoskeletal pain utilizing acetaminophen as the first-line agent under a nurse-initiated order. Following education and implementation, weekly reports generated using the International Classification of Diseases codes of fractures were reviewed to assess compliance with the protocol. This study evaluates the frequency of a second pain medication administration and reduction in vital signs and pain scores. RESULTS: Implementation of a pain management protocol reduced median time to pain medication administration to 26 minutes. Overall, 63% (n = 638) of patients required a second pain medication. Of these, 66.5% (348/523) who initially received acetaminophen and 59.7% (286/479) who initially received an opioid required a second pain medication. No significant changes in pre and posttreatment vital signs were found between groups. Patients who initially received opioids experienced a greater reduction in posttreatment pain scores. CONCLUSIONS: Using a standardized pain management protocol in combination with comprehensive education effectively reduces median time to pain medication administration in pediatric patients with long bone fractures. Acetaminophen is a rapid and effective first-line agent for managing pain in this population.
