Self reporting polling. Not necessarily the most reliable.
EG nite that China claims to treat the sickest and patients first with ventilators. We know that aint true
For me, the highlight of this study is that the US is last on the list in prescribing Hydrocloriquin and Z-Pac. The other issue related to this is the only in the US is this treatment being prescribed only for people who are critically ill. This actually infuriates me, especially as a person who goes out into the field in my hospice chaplain ministry every day, exposing myself to sick (not covid-19+) people.
