wcedmisten is using a semi-automated approach to importing this data to allow for manual review of each feature using independently verified data (using hospitals' websites). His workflow follows watmildon's JOSM workflow, except that a Python script is used to preprocess the GeoJSON file into suitable OSM tags to avoid manual retagging effort. This makes the conflation process a lot easier.
First pass: missing hospitals
This just involves looking at the "Reference Only" column in the conflation plugin. This is where hospitals that are unmapped in OSM might be found.

Found 5 or so hospitals that were completely unmapped in OSM. Was able to update tags on many more hospitals.
