The eighth revision of the original (Bertillon’s) classification of causes of death but also encompassing diseases is referenced in this article at the WHO website.
The conference for the eighth revision was organised by the World Health Organisation and held in Geneva in 1965. According to the article above, the eighth revision did not change the essential structure of the classifications.
I undertook a quick search in Medline using the search term “icd-8” which returned 207 articles. Scanning through these there were a few papers that compared ICD-8 with ICD-10 (here, here and here). There were also a few papers comparing ICD-8 with DSM-III (here, here, here and here). This WHO Bulletin article looks at mortality statistics discontinuities between various versions of ICD. Whilst there were one or two other papers featuring ICD-8 diagnoses, ICD-8 was not the focus of those papers.
So in summary, the WHO had taken over the revising of the classifications with the sixth revision which also included the classification rules. In revisions 7 and 8 there weren’t any fundamental changes to the classification.

This is the definition of the Health Information Exchange that I use (Hersh et al, 2015)
‘Health information exchange (HIE), the electronic sharing of clinical information across the boundaries of health care organizations‘
