Insights
This study found that gentamicin was often unnecessarily prescribed, particularly in young children, leading to potential nephrotoxicity. Standard guidelines and audits are crucial to improve gentamicin prescribing practices and prevent drug misuse.
Area of Science:
- Pharmacology
- Clinical Pharmacy
- Infectious Diseases
Background:
- Gentamicin is a widely used antibiotic for serious bacterial infections.
- Evaluating prescription patterns is essential for optimizing antibiotic use and patient safety.
Purpose of the Study:
- To retrospectively analyze gentamicin prescription practices in a hospital setting.
- To identify instances of appropriate and inappropriate gentamicin use.
- To assess the incidence of gentamicin-related adverse events.
Main Methods:
- Retrospective screening of 600 patient case records.
- Analysis of 100 patients who received initial gentamicin treatment.
- Identification of indications, patient demographics, and outcomes.
Main Results:
- Gentamicin was indicated in 71 cases, predominantly in patients under 1 year old.
- Appropriate use was observed in neonatal septicemia, meningitis, and immunocompromised patients.
- Unnecessary prescriptions occurred in 29 cases, including respiratory and gastrointestinal conditions.
- Nine patients experienced gentamicin-related nephrotoxicity.
Conclusions:
- A significant proportion of gentamicin prescriptions were inappropriate, suggesting physician over-reliance.
- Standard treatment guidelines and regular medical audits are recommended to enhance prescribing quality and prevent misuse.
- Improving gentamicin prescribing practices is vital for patient safety and antimicrobial stewardship.
Abstract:
In order to evaluate the prescription practices on gentamicin, we screened retrospectively the case records of 600 patients admitted to this hospital. Of these, 100 received gentamicin, in combination with other antibiotics, as the initial treatment. Therapy with gentamicin was considered to be indicated in 71 cases; 62% were below 1 year. Patients with neonatal septicemia, meningitis, serious staphylococcal infections and those who were immunocompromised received appropriate treatment with the drug. All the bacteria cultured were sensitive to the antibiotic. Gentamicin was unnecessarily prescribed to 29 cases including bronchial asthma (n = 7), bronchiolitis (n = 6) and acute gastroenteritis with dehydration (n = 8). In most of the latter cases, the use of gentamicin indicated the psychologic dependence, of the physician, on the drug. Nine patients showed gentamicin-related nephrotoxicity. Formulation of standard treatment guidelines and regular medical audits are necessary to improve quality of prescribing and avoid misuse of drugs.
