• Data—Neighborhoods and locations where available data indicate persistently high rates of overdose and deaths due to opioids should be prioritized. If data indicate shifting trends in overdose rates and geography, the team should be prepared to mobilize a response accordingly. 

• Lack of current addiction services—The mobile health program should avoid duplicating services as much as possible. If proposed clinical sites have existing addiction services and/or street outreach teams to link homeless or otherwise vulnerable populations, the mobile health program should consider other neighborhoods/locations experiencing service gaps that may benefit more from proposed services. 

• Local stakeholder support—The support of partners and stakeholders in neighborhoods being served can help enhance and expedite program implementation. Selecting pilot sites in areas of demonstrated need that have extensive community backing could give the program the best environment to gain experience and establish best practice before spreading the program to additional sites.

 • Logistical considerations—Logistical considerations that impact the feasibility of establishing an effective clinic might include: 

– The availability of parking in the vicinity of the proposed clinical site

 – The distance of the proposed clinical site from the organizations operating the mobile health clinic (i.e. how far will the staff need to travel?) 

– Proximity to pharmacies to facilitate rapid prescription fills for patients 

– Balancing accessibility with discretion—ideal locations are easy for program participants to travel to, but not so conspicuous as to draw unnecessary attention by onlookers
