A US clinical trial has found that bringing integrated services to people through mobile medical units may help overcome barriers to HIV prevention and addiction care. Participants receiving the mobile service had fewer deaths than those offered peer navigation to existing community services alone.
The NIH announced the results on 4 November. The trial enrolled 409 adults without HIV who injected drugs, had opioid use disorder and were not taking medication for that disorder when they joined. It operated in five US cities.
A promising finding with an important limit
The mobile units combined peer support with HIV prevention, addiction treatment and limited clinical and supportive care for 26 weeks. The comparison group received peer navigation to non-mobile services over the same period.
Deaths from all causes were 71% lower in the mobile-unit group. However, mortality was a secondary outcome. The trial found no difference between groups in the use of daily oral HIV prevention medication or medication for opioid use disorder.
Access is part of treatment
The results point to the importance of how care reaches people who face fragmented services, unstable housing or stigma. They do not establish that a mobile clinic alone prevents HIV, cures addiction or will produce the same mortality benefit in every setting.
The researchers say the findings need replication. The practical question for future work is whether accessible, combined services can sustain engagement and improve outcomes beyond this study, while addressing the low uptake of the preventive and addiction medicines themselves.
