Neurocognitive deficits increase risk of poor retention in care among older adults with newly diagnosed HIV infection

Objective: To evaluate the role of neurocognitive impairment on retention in care across the lifespan in antiretroviral-naive persons newly diagnosed with HIV. Design: A prospective observational study of 138 antiretroviral-naive newly diagnosed HIV-positive participants who presented to an urban clinic between August 2010 and April 2013. Methods: All participants underwent a baseline evaluation that included a neuromedical examination and brief neuropsychological test battery. Retention in care was operationalized as attending at least two visits separated by more than 90 days during the 12-month follow-up period. Results: Fifty-five per cent of participants were retained in care over the study observation period. In a logistic regression controlling for ethnicity, there was a significant interaction between age and neurocognitive impairment in predicting retention in care (P = 0.009). Planned post-hoc analyses showed that neurocognitive impairment was associated with a significantly lower likelihood of retention in care among participants aged 50 years and older (P =.007), but not among younger participants (P> 0.05). Conclusion: Extending prior research on antiretroviral adherence and medication management, findings from this study indicate that neurocognitive impairment may be an especially salient risk factor for poor retention in care among older adults with newly diagnosed HIV infection.
