The Hospital Liaison Committees got their start in Canada in the early 70s.
3 books/volumes were produced in 1973 and became the 'handbook' that was used by JWs in negotiating the no blood care of JW patients who required blood transfusions.
James Penton, in the third edition of his book Apocalypse Delayed, gives some background on how these 'medical' volumes came about:
At the time of the establishment of the hospital committees, a number of large meetings were held in Toronto at which numerous prominent Canadian Witnesses were present. As a result of the "hospital work", three books containing photocopied articles from medical journals and the popular press were produced and bound at the society's Toronto branch. These were Jehovah's Witnesses - Alternatives to Blood Transfusions in Adults, Jehovah's Witnesses - Alternatives to Blood Transfusions in Minors, Jehovah's Witnesses - Alternatives to Blood Transfusions. Most of the material in them was compiled by Alex Tost, a former Watchtower missionary and chemist from Hamilton, Ontario. Interestingly, in preparing these books, no attention was paid to copyright laws.
Penton mentions that the book contains medical studies and clippings from popular press but it also contains legal writings by Glen How and it contains a section of clippings from WT literature supporting the JWs' choice to refuse blood transfusions.
This is the book that was used by the JWs who were negotiating with doctors and hospitals in the 70s. The book carried a lot of weight - the introduction contained a veiled threat that legal problems would arise if the JW patient's wishes (the WT wishes) weren't adhered to, and that threat was backed up by the weight of Glen How's legal articles contained in the volume.
I am grateful to the person(s) who took the time to make one of these volumes available as a digital file, along with a letter by Alex Tost outlining the use of the books. This volume that has been digitized is the pediatrics version.
