Hi Andrea,
The mobile health unit you describe sounds like it did comprehensive screening and referral, which is such important outreach. While not exactly like it, it reminds me of the volunteer pop-up medical centers that happen around the US (https://ramusa.org/). Thousands of volunteer medical providers gather for a few days in a rural area and treat thousands of patients who have no insurance or access to other medical care. It is a band-aid strategy to deliver chronic disease and preventive care to people. Unfortunately, they receive care for only one day, and without follow-up, unless they come back the next year. As you have mentioned, it would be great to implement interventions for prevention rather than band-aid type of transient solutions. I am inspired by the Thomas et al. article to consider what impact the organization could have if, instead of (or in addition to) the thousands of medical volunteers providing medical care for one day, they were guided in Public Health Critical Race Praxis principles (i.e. race consciousness, advocacy via structural determinism, etc).
Thanks for you post!
