Nurse-Initiated Rapid HIV Testing was Cost-Effective and Increased Screening Rates among Veterans


FINDINGS:

  • Nurse-initiated routine screening (i.e. recommending HIV testing to all Veterans) with rapid HIV testing and streamlined counseling increased rates of testing and receipt of test results among Veterans - and was cost-effective compared with traditional risk-based HIV testing strategies.
  • When benefits to sexual partners from reduced transmission was considered, rapid testing with streamlined counseling was even more favorable.
  • Traditional risk-based HIV counseling and testing resulted in the lowest costs and effectiveness.
  • For a Veteran with HIV, nurse-initiated routine screening with traditional counseling/testing increased life expectancy by 0.64 years or 0.47 QALYs compared to traditional counseling/testing. If the nurse-initiated strategy included rapid testing and streamlined counseling, life expectancy increased by 0.87 years or 0.63 QALYs compared to traditional counseling/testing.

IMPACT:
There is sufficient evidence to show that HIV rapid-testing can be an effective means to increase testing and receipt of results among Veterans. HIV/Hepatitis-QUERI has developed implementation tools to increase the use of rapid testing and will disseminate these across VHA.

BACKGROUND:
The CDC recommends that HIV screening be performed routinely for all patients between the ages of 13-64 in healthcare settings, yet HIV testing rates are low, even among individuals with identifiable risk. Also, many patients who are screened do not return for test results. This study examined the cost-effectiveness of three alternative models for implementing HIV testing: traditional HIV counseling and testing; nurse-initiated routine screening with traditional counseling and testing; and nurse-initiated routine screening with streamlined counseling and rapid HIV testing. Investigators used a Markov model developed to assess the cost-effectiveness of voluntary HIV screening in healthcare settings, replicating the rates of HIV testing and receipt of results for each strategy from a previously conducted randomized controlled trial. The RCT included 251 Veterans who received care at one of two VA primary care clinics, with urgent care services. Outcomes in the current study included costs and quality-adjusted life years (QALYs).

LIMITATIONS:

  • Implications for implementation of screening outside a trial are not known (i.e. informed consent and follow-up requirements may have discouraged some patients from participating).
  • The cost-effectiveness analysis assumed that identified patients would have access to HIV care, which is true in VA, but may not be the case in other healthcare settings.

What are HSR&D Publication Briefs?

HSR&D requires notification by HSR&D-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR&D and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR&D based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR&D published articles. Visit the HSR&D citations database for a complete listing of HSR&D articles and presentations.
