The TB clinical corner.

If we’re being honest, the TB programme can feel a bit intimidating. The guidelines are long, the protocols are many, and sometimes nurses would rather avoid working in TB. But TB management doesn’t have to feel overwhelming. Here are a few simple reminders for nurses caring for TB patients.

Always screen for TB symptoms.

Screening should be conducted at every patient encounter, especially in high-burden settings.

Common TB symptoms include:

• Persistent cough

• Fever lasting more than two weeks

• Loss of appetite

• Weight loss or failure to gain weight

• Fatigue or reduced activity

• Night sweats

• Symptoms that persist for more than two weeks without improvement should raise suspicion for tb and prompt further investigation. 

Assess tb exposure history.

A detailed history is essential, Nurses should ask whether the patient has:

• Lived with or been in close contact with someone diagnosed with tb

• Been exposed to someone with a chronic cough

• Shared indoor spaces such as homes, schools, or transport with a tb patient

• Children often develop tb within 12 months of exposure to an infectious tb case, making contact history particularly important. 

Conduct a thorough clinical assessment.

Clinical evaluation should include:

• Vital signs

• Respiratory examination

• Weight measurement and growth monitoring

• Assessment for signs of malnutrition

• Weight monitoring is critical because failure to thrive or weight loss may be an early indicator of tb, particularly in children.

Support the tb diagnostic process.

Diagnosing tb in children and adolescents often requires combining several factors.

Key diagnostic components include:

• Clinical history and symptoms

• Physical examination

• Chest x-ray

• Laboratory testing such as TB-NAAT or culture

• In some cases, tb treatment may be initiated based on clinical evidence even if laboratory confirmation is not available, particularly when symptoms strongly suggest TB. 

• Initiate treatment promptly.

Once TB is diagnosed or strongly suspected, treatment should begin as soon as possible.

Standard treatment for drug-susceptible tb includes first-line medicines such as:

• Rifampicin

• Isoniazid

• Pyrazinamide

• Ethambutol

• Medication doses are based on the patient’s weight, and weight should be monitored regularly to ensure appropriate dosing. 

Monitor patients throughout treatment.

Nurses must regularly assess patients to ensure treatment success, monitoring should include:

• Clinical improvement of symptoms

• Weight gain or nutritional recovery

• Medication adherence

• Monitoring for adverse drug reactions

• Patients who deteriorate during treatment require urgent reassessment to rule out treatment failure, drug resistance, or complications. 

• Screen for HIV and other co-morbidities, Tb and HIV frequently occur together.

  
  

All patients being evaluated for TB should be offered:

• HIV testing

• Linkage to antiretroviral therapy if HIV positive

• Integrated tb and HIV care improves patient outcomes and reduces complications. 

Promote infection prevention and control.

Tb is transmitted through the air when infected individuals cough or breathe out droplets containing tb bacteria.

Nurses should reinforce infection prevention measures such as:

• Adequate ventilation in clinics and homes

• Mask use where appropriate

• Early identification and treatment of infectious cases

• Screening household contacts

• Preventing transmission is a key component of TB control. 

Provide patient education and psychosocial support.

Tb treatment requires several months of continuous medication, making patient support essential.

Nurses should educate patients and caregivers on:

• The importance of completing treatment

• Possible medication side effects

• Infection prevention at home

• The importance of follow-up visits

• Patient-centered care improves adherence and treatment success. 

Key takeaway for nurses.

Effective TB management requires a holistic approach that includes early screening, prompt diagnosis, appropriate treatment, ongoing monitoring, and strong patient education. By maintaining a high index of suspicion and supporting patients throughout treatment, nurses play a vital role in reducing the burden of TB and improving patient outcomes in South Africa.
