In the mid-1990s, various colleagues and I were commissioned by the UK Department of Health to produce comprehensive narrative reviews of the literature on nurse practitioners and on physician assistants to inform policy discussions. These reviews were published in a single report, ‘The Mid-Level Practitioner‘ by the Trent Institute for Health Services Research (Discussion Paper 96/02) in 1996. As a result of various NHS and university reorganizations, the Trent Institute series has become difficult to access but I do receive occasional requests for copies of this and other reports. I am gradually scanning those to which I contributed and making them available online. Given the renewed UK interest in possible changes to role boundaries within the division of labour in healthcare, this work may still have value in documenting the evidence considered when this topic has previously been considered and the conclusions that were reached at the time.
