i'm doing it now. not actually completing a fellowship, but i'm in the midst of a "mentorship." i will be eligible to sit for the h&pm boards under the experiential track when it is next offered 10/10. i very seriously considered pursuing a fellowship, but then found an opportunity to join a palliative care team with a couple of docs that were interested in guiding me through the learning curve. just simply jumped into mix after residency completion, learning much as i go. there are a plethora of similarities in philosophy and practice between pm&r and h&pm and a physiatric presence certainly compliments the multidisciplinary and interdisciplinary approach to end-of-life care. the blending of the two feels very intuitive for me. pm me if you want to chat about my experience.
