Abstract
Introduction The health workforce is an integral component of the healthcare system. Comprehensive, high-quality data on the health workforce are essential to identifying gaps in health service provision, as well as informing future health workforce and health services planning, and health policy. While many data sources are used in Australia for these purposes, the quality of the data sources with respect to relevance, accessibility and accuracy is not clear.
Methods and analysis This scoping review aims to identify and appraise publicly available data sources describing the Australian health workforce. The review will include any data source (eg, registry, administrative database and survey) or document reporting a data source (eg, journal article, report) on the Australian health workforce, which is publicly available and describes the characteristics of the workforce. The search will be conducted in 10 bibliographic databases and the grey literature using an iterative process. Screening of titles and abstracts will be undertaken by two investigators, independently, using Covidence software. Any disagreement between investigators will be resolved by a third investigator. Documents/data sources identified as potentially eligible will be retrieved in full text and reviewed following the same process. Data will be extracted using a customised data extraction tool. A customised appraisal tool will be used to assess the relevance, accessibility and accuracy of included data sources.
Ethics and dissemination The scoping review is a secondary analysis of existing, publicly available data sources and does not require ethics approval. The findings of this scoping review will further our understanding of the quality and availability of data sources used for health workforce and health services planning in Australia. The results will be submitted for publication in peer-reviewed journals and presented at conferences targeted at health workforce and public health topics.

Strengths and limitations of this study
This is the first scoping review to map publicly available health workforce data sources in Australia.
Data will be extracted using a customised data extraction tool.
The customised appraisal tool is novel and will help facilitate the application of the findings, though validation of the tool is needed.
Only data sources that are publicly available will be included.
The results will provide an important resource for health planners, policy-makers and researchers both nationally and internationally.
Introduction
The health workforce is a core element of any healthcare system. Large differences in the distribution of the health workforce currently exist within many countries, including Australia. This workforce maldistribution is evident in terms of both geographical location and skill-mix.1 For instance, in rural areas, there are major challenges regarding the accessibility, availability and appropriateness of health services.2 These restrictions on the accessibility of health services (ie, services staffed by appropriately qualified health practitioners) have been shown to be associated with poorer health outcomes, including lower cancer survival rates and increased prevalence of diabetes complications.3
Health workforce data can assist in addressing the healthcare needs of a population by informing health services and health workforce planning. These data can be used to (1) diagnose gaps in workforce supply, (2) ascertain workforce recruitment and retention issues, (3) uncover areas of workforce maldistribution and (4) identify priority areas for research, and workforce education and training.
Government and non-government agencies collect workforce data for various purposes. However, the quality of these data sources with respect to relevance, accessibility and accuracy is not entirely clear, partly because a comprehensive review of Australian health workforce data sources has not been performed to date. Mapping available data sources by way of a scoping review may help further our understanding of the quality of these data sources, and their potential utility for health workforce and health services planning in Australia. This may in turn facilitate better data utilisation, highlight areas where there is unnecessary duplication of effort, and identify areas where data are lacking.4
Information on the health workforce can be gathered from primary and secondary data sources. For the purpose of this review, primary data sources are those that have been collected specifically for health workforce use. They can include professional registries, administrative databases and workforce surveys. Secondary data sources, on the other hand, provide secondhand information on the health workforce, often drawing data from multiple sources; reviews and discussion papers are examples of this category. Both primary and secondary data sources can be helpful in informing health workforce and health services planning. Accordingly, the objective of this scoping review will be to identify and appraise publicly available primary and secondary data sources describing the Australian health workforce.
Methods and analysis
Design
This scoping review will use an adaption of the approach proposed by Peters et al,5 which extends the Arksey and O’Malley framework.6 The approach will be modified to map data sources rather than map literature. The database search will cover the period from 1 January 2000 to 31 December 2019. The approach will consist of the following stages: identifying review questions, determining the selection criteria and search strategy, undertaking extraction, charting, appraisal and reporting of the results. Each stage is further described below.
Identifying review questions
Primary research question
Which health workforce data sources are publicly available and can be used to inform health workforce and health services planning in Australia?
Secondary research questions
Which primary data sources are available to inform the health workforce and health services planning in Australia?
Which secondary data sources are available to inform the health workforce and health services planning in Australia, and which data sources do they draw from?
To what extent are primary data sources used to inform the health workforce and health services planning in Australia?
What is the quality of health workforce data sources in terms of relevance, accessibility and accuracy?
Determining selection criteria
Data source: This review will include any data source (eg, registry, administrative database, survey) or document reporting a data source (eg, journal article, report), published or unpublished, which meets the following inclusion criteria:
Data source is publicly available, meaning the data source is available for general public consumption or by request, subscription or purchase.
Data can be extracted on the Australian health workforce (at the national, state and/or regional level).
Data source describes the characteristics of the health workforce (eg, type of health worker, demographic profile (eg, age, sex, geographical location)).
Data sources will be limited to those containing data collected from the year 2000 onwards. This will ensure the source is likely to be accessible, and is still pertinent for health service planning purposes (eg, while recent data may be used to calculate current workforce estimates, older data may be used to calculate trends over time).
Concept: The key concept of this review is the health workforce. This refers to any discipline that provides health services (eg, nursing, medicine, physiotherapy, chiropractic), in any setting (eg, private practice, community centre, hospital, residential facility) and in any industry (eg, healthcare, social assistance, education, public health).
Context: The context of this review is Australia. This may include data reported at the national, state and/or regional level.
Search strategy
The search which was developed with the assistance of a librarian, will be conducted using an iterative process. This will include the following steps5:
Conduct an initial search of at least one bibliographic database and one grey literature source to identify key words used in the title, abstract, description and/or index terms of identified sources/documents (note: this step has been completed).
Perform a search of selected database, detailed below and grey literature sources using the keywords and index terms defined in step 1.
Remove duplicates from the identified sources/documents.
Screen title/abstract/description of identified sources/documents for eligibility.
Access data sources/obtain full-text versions of documents considered eligible in step 4 and screen for eligibility.
Search for other relevant sources/documents in the reference lists of all identified sources/documents and screen for eligibility by following steps 4 and 5.
The first two steps will be conducted by a single investigator. Steps 3–6 will be undertaken by two investigators, independently, using Covidence software (www.covidence.org). Any disagreement between investigators will be resolved by a third investigator.
Information resources
Bibliographic databases: Studies reporting Australian workforce data will be sourced through: MEDLINE, EMBASE, Ovid EMCare, Scopus, Web of Science, InfoRMIT, Joanna Briggs Institute, PsycINFO, EconLit and The Cochrane Library.
Grey literature: Unpublished documents, or those published in non-commercial form, will be identified using: Google, Google Scholar and the WHO website. The following websites also will be interrogated for eligible data sources: professional associations (eg, Australian Association of Social Work), universities/institutes (eg, Flinders University National Institute of Labour Studies), government agencies (eg, Medicare Benefits Schedule, Australian Bureau of Statistics, Health Workforce Australia/Australian Department of Health, Australian Institute of Health and Welfare), workforce/registration agencies (eg, Australian Health Practitioner Regulation Agency (AHPRA)), registries (eg, metadata online registry) and pertinent survey/project sites (eg, Medicine in Australia: Balancing Employment and Life (MABEL) survey).
Preliminary search terms
See online supplementary appendix 1 for detailed secondary source search strategy.
Supplemental material
Health workers/health occupations.
Workforce.
Data Planning.
Australia.
1 AND 2 AND 3 AND 4 AND 5.
Limit: year 2000 onwards.
Primary source search strategy will contain key terminology modified from the secondary search strategy to capture the most pertinent concepts:
‘Health workforce’ OR ‘health personnel’ OR ‘health occupations’ OR ‘workforce planning’ OR ‘health planning’ AND Australia.
Limit: year 2000 onwards.
Data extraction and charting
A customised data extraction tool was developed for this review (table 1). The tool will be used to extract information from eligible data sources/documents, including name of agency, data type, aim, years and workforce type (table 1). Data extraction will be performed by two investigators, independently. The extracted data will be compared and any disagreements will be resolved by discussion. In the event that the two investigators cannot reach consensus, a third investigator will be consulted to resolve the dispute. Table 2 presents an example of how the data will be charted, using the AHPRA data source as an exemplar.
Data collection tool

Critical appraisal
The quality of included data sources will be assessed using a customised critical appraisal tool informed by the Data Quality Assessment Tool for Administrative Data framework.7 The tool comprises 10 items, captured under three themes: relevance (including discipline (type of health worker) coverage, variables of interest, recency, frequency of data collection, and reference time period), accessibility (including access to the dataset and access to data) and accuracy (including representativeness, geographical coverage and missing data). Each item will receive a score ranging between 1 and 3, with lower scores indicating lower quality or scope (table 3). Two investigators will appraise each included data source, independently. If any disagreement cannot be resolved by discussion, a third investigator will be consulted to arbitrate the decision.

Reporting of results
The reporting of the scoping review will be informed by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for Scoping Reviews Checklist.8 The results of the search, and each screening step, will be presented in a PRISMA flowchart. The findings from the charting and appraisal tools will be summarised and presented in tabular form using the categories from the respective tools. The relationships between the primary and secondary data sources will be illustrated in a network diagram expressing the relationship in terms of data sources, that is, which primary data source contributed to the secondary data sources.

Discussion
The health workforce plays a pivotal role in the provision of healthcare, and is therefore a fundamental component of the healthcare system. However, these human resources are costly, contributing between 9% and 80% (mean 42%) of total healthcare expenditure, globally.9 In an era of healthcare rationalisation, the quantity and composition of the heath workforce needs to be adequately justified and prioritised.
Comprehensive, high-quality data on the health workforce can assist in informing health policy, as well as health workforce and health services planning. This is critical to ensuring that the healthcare needs of the population are adequately met. Such data may also assist in improving healthcare efficiency by ensuring that services are delivered in a timely and appropriate manner to the people who need them.
While many workforce data sources are used in Australia, to our knowledge, there has not been a comprehensive review or appraisal of these health workforce data sources. To address this knowledge gap, we will conduct a scoping review to identify, and assess the quality of, publicly available data sources describing the Australian health workforce. Results from this review can be used to inform health workforce and health services planning, as well as policy development, to help overcome barriers to the provision of accessible, available and appropriate health services for all Australians.
The scoping review will provide a comprehensive mapping of available health workforce data sources in Australia identifying and describing health workforce data sources in terms of breath and depth. The insights gained from this review will help to identify areas where data sources could be improved, so they can better inform policy. The results will be relevant for international comparison and further research in this field.
Ethics and dissemination
The results will be published in peer-reviewed journals relevant to health workforce and public health and presented at conferences.
