Professor Andrew Jull

Registered nurse and clinical epidemiologist, University of Auckland’s School of Nursing

Professor Andrew Jull is a registered nurse and clinical epidemiologist at the University of Auckland’s School of Nursing as well as Senior Research Fellow at the National Institute for Health Innovation. Andrew has authored book chapters on evidence-based practice and taught evidence-based nursing since 1999. He was Co-editor of Evidence Based Nursing 2002-2009 and is an editor with the Cochrane Wounds Review Group. Andrew has been principal investigator five clinical trials as well as co-investigator on eight other trials. He has led or been involved in the development of three New Zealand clinical guidelines, four Cochrane systematic reviews, and is the Clinical Advisor on a national project to improve pressure injury management in New Zealand. Andrew has published more than 120 publications, is highly cited, and has an international reputation for the quality his work in venous leg ulcers.

The Cochrane Library is the first place I look for systematic reviews addressing my clinical questions of interest, whether to identify gaps in the research or to provide evidence to support changes in clinical practice. The earliest occasion I can recall using Cochrane Library was in 1997, when I was leading the development of the New Zealand guidelines for managing leg ulcers. One clinical question we needed to answer was whether pentoxifylline increased healing in venous leg ulcers. At that time, there was no systematic review in the Cochrane Library, but there were randomized controlled trials. So I registered the title and conducted the first systematic review of pentoxifylline for treating venous leg ulcers, which was published in the Cochrane Library (and then in Lancet). We used that systematic review to inform the New Zealand guidelines, as have many other guidelines since. There have been countless times since that time that I have used the Cochrane Library to identify gaps in the evidence base for future research.

More recently, my hospital has been working to improve pressure injury prevention over the last 7 years. Several Cochrane systematic reviews have helped inform clinical practice, including the reviews on risk assessment for pressure ulcers, repositioning to prevent pressure ulcers and support surfaces for preventing pressure ulcers. The last review provided us with the evidence we needed to make alternating pressure mattresses more available to patients at high risk of developing pressure ulcers. The evidence from the Cochrane Library has helped our hospital to significantly reduce pressure injury prevalence.
