You can bank about 50 hours from scribing as "shadowing," but I would consider some shadowing in hospital settings if available, especially in departments not represented by shadowing.
Non-clinical volunteering is suboptimal. You must have in-person experience, and virtual crisis text line does not cut it. You must have at least 150 hours to avoid getting screened out at most schools, but if you are shooting for "brand schools," I always recommend 250 hours minimum, which still is below THEIR pool average (many other applicants will have hundreds to thousands of hours of service orientation). Food distribution fits service orientation, but can you get enough hours in this bucket before applying to optimize your chances?
