Abstract

Background: Antibiotic de-escalation therapy plays a vital role in reducing the risk of bacterial resistance across the globe. This study elucidates the significance, determinants, and outcomes pertaining to Antibiotic De-escalation (ADE). The ADE is acknowledged as a crucial component within Antimicrobial Stewardship Programs (ASPs). The proliferation of antimicrobial-resistant bacteria arises as an anticipated outcome of the extensive utilization of antibiotics, heightening researchers' apprehensions regarding this global challenge.

Objective: The primary objective of the study was to evaluate the usage of antibiotics in terms of clinical outcomes (re-admission within 30 days and therapy outcomes upon discharge), adverse events, duration of de-escalation, and duration of hospitalizations among pediatric patients admitted to a tertiary care hospital due to various infectious diseases.

Methods: A retrospective study was conducted during a four-month period, from January 2022 to April 2023, at a tertiary care facility in Ajman, United Arab Emirates. Participants included in this study were based on specific inclusion and exclusion criteria.

Results: A total of 200 pediatric records were screened. The majority of participants, accounting for 66.0%, were female, and 54.0% were classified as Arabs in terms of race. The mean age was 7.5 years (± 2.8). The most prevalent symptoms reported were fever (98%), cough (75%), and sore throat (73%). Male participants were more inclined to present with bacterial infections (88.2%) compared to viral infections (3.8%), bacterial and viral co-illnesses (2.5%), or parasitic infections (1.3%) at the time of admission. Regarding clinical outcomes, 27% of patients were readmitted with the same infection type, while 52% did not experience readmission. The analysis also included information on the number of patients within each antibiotic therapy duration category, alongside the mean duration of antibiotic de-escalation in hours with standard deviation (± SD). The statistical significance of these associations was assessed using P-values, revealing a significant relationship (P < 0.0001) between the duration of antibiotic therapy and the time required for antibiotic de-escalation.

Conclusion: The study's analysis revealed that individuals readmitted to the hospital, irrespective of whether they presented with the same or a different infection type, exhibited prolonged durations of antibiotic de-escalation. This observation underscores the potential influence of the patient's clinical trajectory and the necessity for adjunctive therapeutic interventions on the duration of antibiotic de-escalation.
