Use of Meropenem in a Tertiary Pediatric Hospital in Costa Rica and Its Role in the Era of Antimicrobial Stewardship.

Background Understanding antibiotic profiles and their resistance patterns can improve hospital quality care and optimize clinical outcomes. This paper characterizes the use of meropenem in the National Children's Hospital of Caja Costarricense del Seguro Social (CCSS) in Costa Rica, and its role in antibiotic stewardship. Methods This is a retrospective observational study from hospitalized patients under 13 years of age that received meropenem as part of their treatment. Patients were identified through medical and pharmacy records. Data was summarized using frequencies and percentages for categorical variables, means and standard deviations for normally distributed continuous variables, and medians with interquartile ranges (IQR) for non-normally distributed continuous variables. Results A total of 181 of the 309 selected patients met inclusion criteria. Median age was 21 months (IQR: 4.0-79.0). Mean length of stay was 31 days (16.0-58.0). The most frequent diagnosis was septic shock (29%). 87% of patients received at least one antibiotic prior to receiving meropenem; 71% of patients received a second antibiotic simultaneously with meropenem. In 113 (62%) cases, meropenem was prescribed as empirical therapy. The most frequent isolate was extended-spectrum ß-lactamase Escherichia coli (24%). 74% of patients who received meropenem as targeted therapy had a favorable outcome. Conclusions Meropenem can be used as monotherapy for complicated, multi-drug resistant, gram negative, bacterial infections, due to its susceptibility profile, convenient dosing schedule, and minimum adverse effects. However, it should be restricted to cases where no other drug is available in order to safeguard its value.

Febrile neutropenia is a life-threatening condition that requires immediate attention, especially in patients with chemotherapy-related neutropenia. Patients with febrile neutropenia have a much greater risk of developing bacterial disease, and fever may be the only indicator of severe bacterial infection. Adequate management of febrile neutropenia emphasizes early recognition of patients, risk stratification, and antibiotic therapy administration during the first 60 minutes of admission to an emergency room. Not all children with febrile neutropenia carry the same risk of morbidity and mortality, so in recent years, efforts have been made to distinguish between high-risk patients where more aggressive hospital management is required. In children classified as low-risk, outpatient management may be considered initially or after 72 hours, whilst high-risk patients should be hospitalized and managed with parenteral antibiotics.

Resumen La neutropenia febril es una condición que puede amenazar la vida y que requiere de atención inmediata, particularmente en pacientes en que la misma está asociada a tratamientos con quimioterapia. Estos pacientes tienen un riesgo mucho mayor de desarrollar enfermedades bacterianas, y en ellos, la fiebre puede ser el único indicador de enfermedad bacteriana grave. El manejo adecuado de la neutropenia febril da énfasis en la identificación pronta de los pacientes, estratificación del riesgo y antibioterapia iniciada durante los primeros 60 min del ingreso al servicio de emergencias. No todos los niños con neutropenia febril conllevan el mismo riesgo de morbi-mortalidad, por lo que en los últimos años se han hecho esfuerzos para distinguir entre pacientes de alto riesgo en quienes se recomienda el manejo hospitalario más agresivo. En pacientes que se clasifican como de bajo riesgo se puede considerar el manejo ambulatorio inicial o después de 72 h, mientras que en aquellos de alto riesgo se recomienda hospitalizar y manejar con antimicrobianos parenterales.
