ABSTRACT
OBJECTIVES: Vaso-occlusive episodes (VOEs) account for the majority of emergency department (ED) visits for children with sickle cell disease (SCD). We hypothesized that addressing key barriers to VOE care would improve receipt of analgesics and outcomes. METHODS: A quality improvement (QI) initiative was conducted from September 2010 to April 2014 to streamline VOE care in an urban pediatric ED. Four interventions were used: a standardized time-specific VOE protocol; intranasal fentanyl as the first parenteral pain medication; an SCD pain medication calculator; and provider and patient/family education. Data were collected for 3 outcome measures (mean time from triage to first parenteral opioid and admission/discharge decision, and proportion discharged from the ED); 1 process measure (mean time from triage to initiation of patient-controlled analgesia); and 4 balancing measures (mean time from triage to second intravenous opioid dose, 24-hour ED readmission, respiratory depression, and length of stay). RESULTS: There were 289 ED visits in the study period. Improvements were seen in mean time to: first dose of parenteral opioid (56 to 23 minutes); second opiate intravenous dose (106 to 83 minutes); admission and discharge decisions (163 to 109 minutes and 271 to 178 minutes, respectively); and initiation of patient-controlled analgesia (216 to 141 minutes). The proportion discharged from the ED increased from 32% to 48% (χ(2) = 6.5402, P = .01). No increase in 24-hour readmission, respiratory depression, or inpatient length of stay was observed. CONCLUSIONS: Using VOE-specific interventions, we significantly improved VOE care for children. Studies are needed to determine if these results can be replicated.

The in vivo tissue response to a newly developed fiber-reinforced calcium phosphate cement (CPC) formulation was assessed using a well-established rabbit calvarial defect model. Bilateral subcritical sized (8-mm diameter) defects were surgically created in the parietal bones of each rabbit (a total of 48 rabbits), and randomized to be filled with either the new fiber-reinforced formulation, a conventional CPC (positive control), or left unfilled (negative control). The implant sites were subsequently retrieved after 12, 24, and 52 weeks postsurgery. Each specimen, including the parietal bone craniotomy and underlying brain, were recovered at necropsy and the tissue responses were assessed by histology. The resulting histological slides indicated that there was no evidence of severe inflammatory responses or osteolysis. The data showed new dural and pericranial bone formation along the implants, as well as excellent bone-to-implant interfaces in all of the CPC-filled defects. These results suggest that the biologic response to the new fiber-reinforced CPC formulations and conventional nonreinforced CPC are very similar, and both demonstrate excellent biocompatibility as well as an overall osteophylic response.
