How is the effectiveness of INH therapy evaluated?

• A. By assessing patient feedback and satisfaction
• B. Based on clinical improvement and microbiological response
• C. Through financial cost analysis of treatment
• D. By tracking the number of patients treated

Answer: (B)

The effectiveness of INH (Isoniazid) therapy is primarily evaluated based on clinical improvement and microbiological response. This approach is rooted in the need to assess how well the treatment is achieving the desired outcome of eradicating or controlling tuberculosis bacteria within the patient's body. Clinical improvement refers to the evaluation of the patient's symptoms and any improvements in their overall health status after initiating therapy. This can include reductions in coughing, fever, and weight gain. The microbiological response is critical because it provides objective evidence of the treatment's effectiveness. This is typically evaluated through the use of sputum cultures, chest X-rays, and other diagnostic tests to confirm the absence of pathogens or a marked reduction in their numbers. These methods allow healthcare providers to monitor the success of the therapy, ensuring that the patient is responding appropriately, and can guide future decisions about treatment adjustments if necessary. While patient feedback, financial considerations, and the number of treated patients are important factors in the overall management of tuberculosis, they are not direct measures of the efficacy of INH therapy itself. The primary focus remains on tangible health outcomes and laboratory results, making the evaluation of clinical improvement and microbiological response the standard practice in assessing the effectiveness of INH therapy.
