That would've been nice. If Kerr, as described, has had trouble presenting even his quantifiable metrics, polling his hospice patients and using statistics on the responses, to other professionals, I doubt there's a way to get published. Maybe an observation without a question?
Well a handful of anecdotes aren't "actual research". Not knocking it off per se, but yes, further research is needed.
Also, I couldn't find a link to the empirical work alluded in the piece.
