ICD-10: T36.5X6

The ICD-10 code T36.5X6 refers to the underdosing of aminoglycosides, a class of antibiotics commonly used to treat serious infections caused by gram-negative bacteria. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this condition is crucial for healthcare providers to ensure appropriate management and treatment.

Clinical Presentation

Overview of Aminoglycosides

Aminoglycosides, such as gentamicin, tobramycin, and amikacin, are effective against a variety of infections, particularly those caused by aerobic gram-negative bacteria. They are often used in hospital settings for severe infections, including sepsis and pneumonia. Underdosing occurs when the administered dose is insufficient to achieve therapeutic levels, potentially leading to treatment failure and worsening of the patient's condition.

Signs and Symptoms of Underdosing

The clinical signs and symptoms of underdosing may not be immediately apparent, as they can overlap with the underlying infection being treated. However, some common indicators include:

• Worsening Infection Symptoms: Patients may exhibit signs of persistent or worsening infection, such as fever, chills, increased heart rate, and respiratory distress.
• Delayed Clinical Improvement: A lack of expected improvement in clinical status after starting aminoglycoside therapy may suggest underdosing.
• Laboratory Findings: Blood tests may show elevated white blood cell counts (leukocytosis) or other markers of infection, indicating that the antibiotic is not effectively controlling the infection.

Patient Characteristics

Risk Factors for Underdosing

Certain patient characteristics can increase the risk of underdosing aminoglycosides:

• Renal Function: Patients with impaired renal function may require dose adjustments to avoid toxicity, and if not properly managed, they may receive subtherapeutic doses.
• Body Weight and Composition: Dosing of aminoglycosides is often based on body weight. Obese patients or those with altered body composition may not receive adequate dosing if standard weight-based calculations are used.
• Age: Elderly patients may have altered pharmacokinetics, necessitating careful monitoring and potential dose adjustments.
• Concurrent Medications: Patients on other medications that affect renal function or interact with aminoglycosides may be at risk for underdosing if their overall treatment regimen is not carefully managed.

Clinical Monitoring

To prevent underdosing, healthcare providers should monitor:

• Therapeutic Drug Monitoring (TDM): Regular measurement of aminoglycoside levels in the blood can help ensure that patients are receiving adequate doses.
• Clinical Response: Continuous assessment of the patient's clinical status and laboratory results is essential to determine the effectiveness of the treatment.
