Hypothesis
What factors predict adherence to isoniazid treatment among HIV-infected adults?
Conclusion
Ensuring adequate drug availability at pharmacies is crucial for TB prevention, and in-house urine tests can effectively assess adherence.
Supporting Evidence
- 28% of participants had negative urine tests indicating non-adherence.
- Patients who believed INH was safe were less likely to have negative tests.
- Longer time since last reported INH dose increased the likelihood of a negative test.
Takeaway
This study looked at how well people with HIV stick to their medicine to prevent tuberculosis, finding that some pharmacies run out of the medicine, which makes it hard for patients to take it.
Methodology
Cross-sectional study using a questionnaire and urine test strips to measure adherence.
Potential Biases
Potential bias in self-reported adherence due to social desirability.
Limitations
The study only measured adherence at a single point in time and did not follow up with participants.
Participant Demographics
Mean age 35, 76.7% female, average household income $238.
