To the Editor: As systematic reviews in the health literature increase,1 there is an emerging theme of reporting the geographic location of included studies.2,3,4,5,6,7 Approaches to classifying the geographic location of studies have varied. In the cases of Jennings and colleagues5 and Beks and colleagues,6 the authors captured information on study location and then assigned a geographic category. Jennings and colleagues5 followed the classification used by Eades and colleagues8 and combined RA1 and RA2 (originally based on the Australian Statistical Geographical Classification – Remoteness Area)9 to form an urban category. Although these two categories are both urban areas, the Remoteness Areas (RA) imply varying access to services. Beks et al6 opted to report on all five Australian Statistical Geography Standard (ASGS‐RA) categories. Acknowledging the different research questions — the commonality being a better understanding of Aboriginal health activity — Jennings et al5 concluded that urban areas (reported as a combination of RA1‐Major Cities of Australia and RA2‐Inner Regional Australia) were under‐represented, whereas Beks et al6 concluded that RA2‐Inner Regional Australia, RA3‐Outer Regional Australia and RA4‐Remote Australia were under‐represented.
When reporting systematic reviews, we recommend that results be presented using all available categories (eg, the five categories of the ASGS‐RA). Authors can then combine categories as required to address their specific research question. Of the reviews identified,2,3,4,5,6,7 the Modified Monash Model (MMM) is yet to be applied.10 With seven categories, the MMM builds upon the five categories of the ASGS‐RA and uses population and road distance to add further granularity. Given the large number of studies that are typically included in a review, it is likely there will be examples across multiple categories.
There is direct contemporary policy relevance in adopting the MMM, which spans workforce (eg, Department of Health programs are transitioning to MMM), research translation (eg, 2020 Rapid Applied Research Translation Grant Opportunity), and service delivery (eg, Medicare rebates on telehealth psychology consults).11
A uniform approach to the geographic classification of included studies in systematic reviews would enable greater comparability of findings across reviews. Consistent reporting using the MMM will likely enhance the uptake of health research, and subsequent systematic reviews, by policymakers and funding agencies. This will assist the objective allocation of resources and evaluation of activity of geographically focused programs.
