The Role Of The Pharmacist In The Treatment Of Infantile Botulism, Rachel E. Huntsman, Abigail Schauble

HCA Healthcare Journal of Medicine

Infantile botulism is a potentially devastating disease caused by ingestion of Clostridium botulinum spores through food products or dust particles. The toxin produced by the spores can lead to descending paralysis requiring hospitalization for supportive care which sometimes includes mechanical ventilation. Human Botulism Immune Globulin-Intravenous (BIG-IV or BabyBIG) from the Infant Botulism Treatment and Prevention Program (IBTPP) has been shown to greatly improve outcomes. A previously healthy 5-month-old infant was admitted to her regional hospital for poor feeding and lethargy. When the weakness progressed and she had trouble with protecting her airway, she was intubated and transferred to our institution. …

Implementing A Clinical Practice Guideline For Pediatric Appendicitis Safely Reduced Health Care Use And Improved Antimicrobial Stewardship, Jack Vernamonti, Robin Cotter, Jennifer Jubulis, Kartikey Pandya

Journal of Maine Medical Center

Introduction: Appendicitis is the most common emergency surgical disease in children. Those with perforated appendicitis have a more complicated and varied course. Through a clinical practice guideline (CPG), we sought to reduce computed tomography scans, laboratory draws, and exposure to broad-spectrum antibiotics without adversely affecting length of stay, hospital readmission, or repeat antibiotic administration.

Methods: Electronic records were retrospectively reviewed before and after CPG implementation, and data was collected in REDCap.

Results were reported as mean or percent incidence, and statistical analysis was done using a Student’s t-test, Mann-Whitney U test, or Pearson’s χ2 with P < .05 considered significant. Results: One hundred patients with a perforated appendix (50 before and 50 after CPG implementation) were included in our analysis. Length of stay (4.98 vs 4.46 days; P = .25), hospital readmission rate (10% vs 14%; P = .54), and additional antibiotic administration (2% vs 4%; P = .56) did not change. We observed no difference in the Pediatric Appendicitis Score (9 vs 9; P = .48) and a trending increase in evaluation at an outside hospital (56% vs 74%; P = .06). Rates of computed tomography scans did not differ overall (50% vs 40%; P = .31), but showed a decreasing trend at our institution (30% vs 12%; P = .06). We also found fewer post-operative laboratory studies (90% vs 38%; P < .01) and patients who received broad-spectrum intravenous antibiotics (92% vs 18%; P < .01).

Discussion: Through implementing the …
