This has been moved to the [Wikipedia article on HPSR](https://en.wikipedia.org/wiki/Health_policy_and_systems_research) which still needs work. The HPSR article is one among several [Wikiproject engagements]. Meanwhile resources like the Lejondal report and the following resources from Sumit Kane. The following two volumes by IDRC could potentialy be the earliest written instances of HSR kind of thinking that is wider today although it is not clear how/why IDRC receded from such foundational investments in agenda-setting on HSR/HPSR (have they?)
This is the HSR book (two Vols) from 1991 that we were talking about.
