Hypothesis

Can routine monitoring of CD4 T cell counts and plasma HIV viral load improve the understanding of entry into care for newly diagnosed HIV-infected individuals?

Conclusion

Routine monitoring of CD4 T cell counts and plasma HIV viral load can significantly enhance the identification of individuals entering HIV medical care after diagnosis.

Supporting Evidence

  • Routine surveillance methods identified 101 cases entering care.
  • Monitoring increased confirmed entries into care by 25%.
  • Being interviewed by a public health investigator significantly increased the odds of entering care.

Takeaway

This study shows that checking blood tests can help health workers see if people with HIV are getting the care they need after being diagnosed.

Methodology

The study involved monitoring initial primary care visits and collecting data from patients, medical providers, and laboratories to assess entry into care.

Potential Biases

Potential biases include social desirability and recall bias from patient and provider reports.

Limitations

The study excluded patients with tests on the same day as diagnosis, which may have omitted some individuals linked to care.

Participant Demographics

Of the 160 participants, 95% were men or male-to-female transgender, with a median age of 35 years; 48% were white, 25% Hispanic, and 19% African-American.
