Abstract
Introduction The shortage of doctors in rural locations is an international problem, contributing to limited access to healthcare and a health disparity between rural and metropolitan populations. To encourage additional doctors to work in rural locations, more doctors than ever are being trained in rural settings. One rural clerkship model that is gaining recognition for fostering rural careers is the Longitudinal Integrated Clerkship. Longitudinal Integrated Clerkship programmes vary in terms of settings and durations, but at their core have the fundamental commonality of continuity, with students learning the curriculum in an integrated manner. The scoping review will synthesise the literature pertaining to medical workforce outcomes of rural Longitudinal Integrated Clerkship programmes, to uncover areas that require further research and establish elements of medical education programme design that positively influence rural workforce outcomes.
Methods and analysis The review will follow Arksey and O’Malley’s six step scoping review framework. MEDLINE, CINAHL complete (EBSCOhost), Scopus, Embase (Elsevier) and ISI Web of Science databases will be searched along with Google, Google Scholar, ProQuest and WHO library database. Single design studies examining the geographic work locations and/or medical specialty of rural Longitudinal Integrated Clerkship graduates will be included. Data from quantitative and mixed-methods studies will be included. Only studies written in English will be included. There will be no date range restriction imposed on the reviewed studies. Two reviewers will independently screen and critically appraise the articles to determine if they meet the inclusion criteria. Data from eligible studies will be extracted for synthesis.
Ethics and dissemination Scoping reviews do not require ethics approval. Results will be submitted to a peer-reviewed journal and may be presented at relevant conferences. The findings will also be shared within the Longitudinal Integrated Clerkship community of medical educators.

Strengths and limitations of this study
To the best of our knowledge, this will be the first scoping review to focus on rural Longitudinal Integrated Clerkships and medical workforce outcomes, seeking to find evidence to mitigate the international problem of medical workforce maldistribution.
The review will follow a rigorous methodology, with the search strategy developed in conjunction with an experienced librarian.
Formal evaluation of the evidence will not be undertaken; however, the review will identify gaps in the literature and generate recommendations for future research.
A limitation is only articles published in English will be considered in the review.
Introduction
The maldistribution of the medical workforce is a global issue, with a myriad of policies and programmes developed to redress this problem and encourage more doctors to work in rural locations.1 2 Within Canada, only 8% of doctors work in rural locations despite approximately 19% of the population residing rurally.3 While in Australia, 79% of doctors work in a metropolitan setting, equating to 454.5 doctors per 100 000 compared with 407.3 in larger rural towns and 119.9 in small rural towns.4
The maldistribution of the medical workforce is not only geographic, but there is now a growing medical specialty divide, with the number of doctors training to work in primary care decreasing and interest in subspecialisation increasing.5 6 Since 2013, the number of Australian subspecialists has grown at three times the rate of generalists.4 Rural communities require general practice (GP) and non-GP specialists with a broad range of generalist skills to meet their community’s healthcare needs.4 Uneven geographical and specialist distribution limits access to healthcare services in rural communities, exacerbating the health status disparity between rural and urban communities, which includes higher mortality rates and lifestyle risk factors, such as smoking, excessive alcohol consumption and levels of obesity.7 The potentially avoidable death rate in Australian rural communities is between 20% and 65% higher than metropolitan communities.4
One of the fundamental polices many countries use to strengthen the rural medical workforce is to embed medical students in rural longitudinal training, with countries such as Australia mandating that 25% of commonwealth supported medical students must be trained in a rural location for at least 12 months.8 Rural medical training is not homogeneous, with two clerkship models prevalent, traditional block rotations (BRs) and longitudinal integrated clerkships (LICs). These clerkship models are inherently different despite often delivering the same curriculum and assessments within the same medical degree.9 LIC programmes can occur across a variety of settings and locations but are more often based in small rural communities attached to a GP/primary care setting and smaller rural health service.10 LIC students learn the curriculum in an integrated manner, gaining exposure to all the required disciplines simultaneously.9 10 Rural BR clerkships are discipline-specific short-term rotations predominately based in hospitals.11
LIC programmes have gained popularity within medical education over the preceding decades and are estimated to have doubled globally between 2010 and 2015.10 A catalyst for the development and international uptake of LIC programmes was to address medical workforce shortages in rural settings.10 The LIC International body, The Consortium of Longitudinal Integrated Clerkships (CLIC) developed a consensus statement on elements that must be present to be considered a LIC programme. Three fundamental components were agreed on (i) medical students participate in the comprehensive care of patients’ over time, (ii) medical students have continuing relationships with these patients clinicians and (iii) medical students meet most the year’s core clinical competencies across multiple discplines simultaneously.12
The initial LIC-related literature focused on confirming the educational benefits and equivalence of the LIC clerkship model when compared with the BR clerkship.13 14 Overwhelmingly, LIC programmes have been found to achieve academic equivalence with BR’s.13 15 Subsequently, LIC-related research expanded focus, finding that LIC programmes foster the development of trusting, continuous relationships with supervisors, healthcare teams and patients, allow students greater access to patients, support active participation in patient care, enhance confidence in clinical skills and heightened preparedness for practice.16–20
Reviews of rural workforce outcomes from extended rural medical training have predominately analysed programme outcomes, without detailed reference to clerkship model. A 2018 scoping review found that when rural immersion programmes such as BRs and LICs are viewed through the same lens, they are moderately successful in increasing the rural supply of doctors, with authors stating that evidence related to the programme design that is most effective in achieving this outcome is still underdeveloped.21 As such, the differences in programme design between the two clerkship models require their relative influence on rural workforce outcomes to be examined.
Over recent years, many rural LIC programmes have reached a level of maturity where graduating cohorts are likely to have completed vocational medical training. Emerging evidence from single site studies, with a variety of methodological approaches have found that rural LICs are effective in influencing rural workforce outcomes.22–25 Studies have reported findings in a variety of ways, including geographic work locations (metropolitan/rural) compared with other training models; workforce locations of graduates who undertake GP; analysis of specific postgraduate years and analyses of the effect of graduates’ other clinical training, in conjunction with the rural LIC year.23 24 26 Medical specialty choice of rural LIC graduates has been examined by a limited number of studies and has primarily focused on graduates who specialise in primary care, as this is the foundation of rural healthcare delivery.26 27 The varied comparative approaches and analyses require mapping.
Moreover, as rural LIC programmes can vary greatly in length, setting and student selection policies, a focused synthesis is required to determine specific patterns associated with rural workforce outcomes and importantly to determine any reported medical programme design elements within the clerkship model that may facilitate this.10 Therefore, this review will synthesise the evidence associated with the geographic and career workforce outcomes of graduates who have participated in a rural LIC programme and identify programme design elements that may facilitate positive rural workforce outcomes.
To undertake the review, a preliminary search of PROSPERO, MEDLINE, the Cochrane Database of Systematic Reviews and the JBI Database of Systematic Reviews and Implementation Reports was conducted, finding that there are currently no previous or under-development systematic reviews specifically on the topic identified. Specific LIC programme research has been synthesised by three narrative reviews (Walters et al (2012), Brown et al (2019) and Bartlett et al (2020)). A review by Thistlewaite et al (2013) although centred on longitudinal placements did not solely focus on rural LIC-specific literature and set the minimum placement duration as 13 weeks, which is in contrast with the CLIC typology that requires the student to meet the majority of the years learning within the programme.14 Brown et al focused on the development and implementation of LICs, while Barlett et al reviewed how to develop sustainable LIC clerkships.28 29 The reviews of Walters et al and Thistlewaite et al briefly examined career and workforce outcomes of LIC programmes, but there were only a very small number of papers, published at least 10 years ago available for inclusion at the time.13 14 Walters et al found that LIC students were positively influenced towards rural career choices but did not delve into the factors that influenced this, stating that they are ‘complex’.13 Thistlewaite et al found that rural LIC programmes improved attitudes towards rural practice but did not focus on actual rural workforce outcomes.14
The scoping review will synthesise the international literature pertaining to medical workforce outcomes of rural LIC programmes, to uncover areas that require further research and establish elements of medical education programme design that positively influence rural workforce outcomes.
Methods and analysis
Methodological framework
The scoping review will be reported in accordance with the preferred reporting items for systematic reviews and meta-analysis extension for scoping reviews (PRISMA-ScR).30
The methodological framework employed will be Arksey and O’Malley’s scoping review steps, which include identifying the research question, identifying relevant studies, study selection, charting the data and collating, summarising and reporting.31 A scoping review has been selected as the most appropriate review type as it enables a means to synthesise the breadth and type of literature available and provides a framework for both mapping the literature, recording the types of studies that have been conducted and identifying any gaps that may exist in the literature.31
Step 1: identifying the research question
This scoping review aims to explore, synthesise and evaluate the literature on rural LIC programmes and rural medical workforce outcomes. The population, exposure and outcomes tool has been used to help formulate the research question;32
Population: medical doctors
Exposure: rural LIC
Outcomes: medical workforce geographic locations (rural/metropolitan) and medical specialty.
The research question is what literature is available on the geographic workforce outcomes of medical graduates who have participated in a rural LIC programme. Specifically:
What literature is available on the workforce outcomes (practice location and medical specialty) of medical graduates who have participated in a rural LIC programme?
How have workforce outcomes (practice location and medical specialty) of rural LIC programmes been described in the literature?
What elements of rural LIC medical programme design have been shown to be positively associated with graduates working rurally?
What gaps exist in the current literature?
Step 2: identify relevant studies
The search strategy will aim to locate published peer-reviewed literature. A preliminary search of MEDLINE and CINAHL was conducted to identify literature on the topic. Known articles on the topic were used to extract appropriate search terms contained in both the titles and abstracts and the index terms used to describe the articles were then applied to develop a full search (online supplemental file 1). The search strategy, including all identified keywords and index terms will be adapted for each individual database which will include MEDLINE, CINAHL complete (EBSCOhost), Scopus, Embase (Elsevier) and ISI Web of Science. The reference lists and journal sites of articles selected for full-text reviews will also be screened and searched to aid in the identification of additional papers.
Supplemental material
Inclusion criteria
The population in the studies will be medical doctors who have participated in a rural LIC programme, either during an undergraduate or graduate medical degree. Participants will be registered medical practitioners, with a recognised geographic work location that has been classified as either rural or metropolitan (comparator group) by the study’s authors. There will be no date range imposed on literature as foundation rural LIC programmes such as the Minnesota Rural Physician Associate Programme have been established since the 1970’s.
The exposure will be participation in a rural LIC programme. For inclusion, studies will need to meet the typology of a LIC as defined by the CLIC.12 Papers that either self-identify as a LIC programme, meet the CLIC criteria or are a recognised LIC programme name associated with the CLIC network will be included.11 Although programmes may vary, fundamental components recommended by the CLIC network to be recognised as a LIC must be present, including (i) medical students participating in the comprehensive care of patients’ overtime, (ii) medical students having continuing relationships with these patients clinicians and (iii) medical students meeting most the year’s core clinical competencies across multiple discplines simultaneously.12 To adhere to the third criteria, the duration of the programme must be for 6 months or more.
The LIC setting must be a rural location. Rural locations will be identified and defined by the authors using a rural classification system of the country or jurisdiction of the LIC programme. For example, in Australia, geographic classifications are reported by the Australian Statistical Geography Standard Remoteness Area and/or the Modified Monash Model, which employ 5-point and 7-point classification systems, respectively, on level of remoteness and population size.33 34 Definitions and/or classifications systems used in studies will be extracted to describe both the rural LIC locations and the medical workforce outcomes. There are inconsistencies in how health research reports geographic locations; therefore, these reviews will align with the emerging recommendation for reviews to present all available geographic categories and then combine as required to answer the research question.35
The outcomes of the included studies will be the geographic and medical specialities of graduates from rural LIC programmes. Medical workforce outcomes are defined as the graduates’ geographic work location and information pertaining to the vocational medical specialty they have either enrolled in, are training in or have completed. Studies will include medical workforce outcomes of rural LIC graduates at any stage of their medical career; prevocational, vocational, or post fellowship.
If it is unclear whether the programme is a LIC or is in a rural location; the corresponding authors will be contacted for further information. If clarification is not forthcoming, the study will be excluded from the review.
Exclusion criteria
Studies from LIC programmes based in metropolitan settings will not be included unless they are compared with rural LIC programmes and results are reported separately.
A 2016 study by Worley et al identified three distinct clusters of LIC programmes, namely comprehensive LICs, blended LICs and LIC-like amalgamative clerkships.10 Programmes considered to be LIC-like amalgamative clerkships, do not meet the third CLIC criteria as students only spent between 6 and 18 weeks (less than 50% of academic year) in these clerkships. As longitudinal duration is a core component required to meet the LIC inclusion, LIC-like studies will be excluded if the duration of the programme is less than 6 months.
Studies reporting on the rural workforce intentions of LIC medical students will not be included due to the complexities associated with reporting on the validity of such rural intentions translating to actual workforce outcomes.36 Furthermore, studies reporting on postgraduate training in LIC like programmes will not be included as postgraduate training is very different to that undertaken in medical school. Participants will not be excluded from the study based on any demographic data such as age, gender, marital status, ethnicity or country in which the LIC programme is undertaken.
Due to resource limitations articles written in languages other than English will be excluded.
Step 3: selection of studies
After the search of all databases, the identified records will be collated and uploaded into Endnote X9 (Clarivate Analytics, PA, USA) with duplicates removed. Two independent reviewers will then screen and assess the titles and abstracts of all papers against the predetermined inclusion criteria using Covidence software.37 Papers deemed to meet these criteria will be retrieved in full. In the event the full-text version of the article is unavailable, the corresponding authors will be contacted to request the full-text version. If the full-text version is not forthcoming, the article will be excluded. Citations of the accepted full-text versions will be reviewed against the inclusion criteria by both reviewers, independently. Reasons why full-text papers are excluded will be recorded and reported in the review. Any disagreements that arise between the reviewers during the selection process will be resolved through discussion, or by a third reviewer. The results of the search will be comprehensively detailed in the final review and presented in a PRISMA-ScR flow diagram.
This review will consider all types of quantitative and mixed-methods study designs for inclusion.
Step 4: data extraction and charting
Data will be extracted from papers included in the scoping review by two independent reviewers. A data extraction tool will be used to facilitate this process and ensure appropriate and standardised information is being extracted by both reviewers (online supplemental file 2).
Supplemental material
To synthesise and allow for meaningful interpretation of the medical workforce outcomes data (geographic work location and/medical specialty), information where available will be extracted on the length of LIC programme, type of medical degree (undergraduate or graduate entry), length of medical degree, year of LIC programme within the medical degree, country/location of LIC, country’s definition of rurality, setting of LIC, LIC programme name, LIC selection or student preference policies and postgraduate year of LIC graduates. Any information on other forms of medical school training LIC graduates have undertaken will also be extracted, for example, locations and types of clerkships undertaken pre-LIC or post-LIC year.
Any other variables that are used in the analysis of rural LIC graduate workforce outcomes such as rural background, gender, age, rural scholarship, type of medical place (eg, bonded, international and domestic) and marital status will also be extracted and presented.
The methodology and statistical analysis employed within the studies will be extracted and charted thematically to allow for meaningful interpretation of the data.
Furthermore, author names, associated institutions and years of publication will be recorded. A draft extraction tool is provided (online supplemental file 2). The draft extraction tool will be modified and revised as required during the process of extracting data from each included paper. Any modifications made will be detailed in the full scoping review. Any disagreements that arise between the reviewers in relation to data extraction will be resolved through discussion, or with a third reviewer. Authors of papers will be contacted to request missing or additional data, where required.
Step 5: collating, summarising, and reporting
The study selection process will be illustrated in a flow chart aligned with PRISMA-Scr. The quantitative results generated by the extraction tool will be presented in diagrammatic or tabular form. A preliminary search of the literature has identified predominately cross-sectional, observational, and retrospective quantitative studies.
As the quantitative studies are heterogeneous, a narrative synthesis will be used to discuss literature on rural LIC programmes and rural workforce outcomes, identifying gaps in the literature and making recommendations on areas that require further research.
Patient and public involvement
No patients or the public were involved in the preparation of this scoping review protocol. Participants in the study are medical doctors who have completed a rural LIC. Results from this scoping review will be used to inform a qualitative study that will aim to provide a deeper understanding of their experience within this clerkship model.
Ethics and dissemination
The study does not involve primary data collection, therefore does not require formal ethics approval from an ethics board.
Results from this scoping review will be submitted to either a peer-reviewed medical education or rural health journal. Presentations of the findings may also be undertaken at medical education or rural health conferences. The review will also be shared within the LIC community of medical educators.
Discussion
This scoping review will explore workforce outcomes of rural LIC programmes, charting how this has been previously researched. The review will follow the scoping review frameworks established by PRISMA-Scr guidelines and the six steps by Arksey and O’Malley.30 31 Any amendments that are required during the review process will be clearly recorded.
Limitations within this scoping review include the absence of resources to include articles written in languages other than English. Variations in the terminology and definitions of rurality between countries, states and jurisdictions may limit the inclusion of some studies and limit the ability for direct comparisons to be drawn. To mitigate this, all studies definitions of rurality will be extracted and recorded. Similarly, some LIC clerkships could potentially be omitted if the key elements required to be considered a LIC are not transparently described.
As LIC programmes vary, those that meet the inclusion criteria will be compared to determine similarities and differences in clerkship structures and authors’ conclusions on programme design that may influence rural workforce outcomes. Synthesis of this literature should enable clear mapping on how workforce outcomes of rural LICs have been studied and what gaps exist in the literature.
