Capability ... what's in a word? Rural Doctors Network of New South Wales Australia is shifting to focus on the capability of rural health professionals.

Rural health services, and the workforces that provide those services, are under unprecedented pressure due to insufficient health workforce numbers and distribution of health workforce weighted to urban areas. This creates health service access issues in rural areas, compounding existing health inequalities between rural and urban people. Many approaches to date have aimed to rectify these issues, with moderate success. In this article we present a call to action to pursue a complementary approach: supporting the capability of the rural health workforce. We hypothesise that further exploring what it means to be a 'capable' rural health professional and what processes or conditions support or erode capability may additionally bolster efforts toward strong rural and remote health systems. The Capability Approach is a theory proposed by Amartya Sen, who was awarded the Nobel Memorial Prize in Economic Sciences in 1998 for this work. Although the Capability Approach inspired, for instance, the UN's Human Development Index, it has not been deeply explored in the context of rural health workforce. While still untested, a focus on capability may assist us in taking a broader view, which encompasses functioning and the freedom to pursue different functioning combinations. The feasible freedom and opportunities are paramount to the concept of capability. We posit that competence is static and the responsibility of the practitioner (and their education), but that capability is fluid and multi-dimensional and the responsibility of the practitioner, community and system. Therefore, we hypothesise that a focus on a Capability Approach, which modulates the relation between the contextual factors and outcomes, may provide us with greater understanding and avenues for action when we aim to improve outcomes such as rural health service sustainability. Developing a list of appropriate capabilities and setting strategies to support capability and its more nuanced domains may present unique opportunities for influence, and these may have positive effects on the rural health workforce. Of course it will need to be determined if improving rural primary health professionals' capability has positive impacts upon quality and access to care, and whether supporting capability is sustainable and worthy of investment.

Hypothesis: improving literacy about health workforce will improve rural health workforce recruitment, retention and capability.

BACKGROUND: One of the key barriers to health in rural areas is health workforce. Poor understanding and communication about health workforce across all stakeholder groups (including the broad community) is very common and can negatively affect the health workforce, recruitment, experiences and outcomes. HYPOTHESIS: In this paper, we propose the concept of literacy about health workforce. We propose this as a specific, actionable extension of the existing and well accepted health literacy concept. We hypothesise that improving literacy about health workforce will improve, in particular, rural health workforce recruitment, retention and capability. IMPLICATIONS OF THE HYPOTHESIS: We propose that literacy about health workforce is important for all members of the health and broader system (e.g. local GP, mayor, workforce agency, health manager, Aboriginal health worker, carers, community health facilitators, patients, schools, local businesses, cultural and recreation groups) because we hypothesise their literacy about health workforce affects their capacity to make informed decisions and take action to manage their health workforce needs in direct synchrony with the community's health needs. We hypothesise that improving literacy about health workforce will improve the effectiveness and efficiency of attracting, recruiting, training, and retaining a high quality, capable, health workforce, and further, will support the development and acceptance of innovative solutions to health workforce crises such as new models of care. This hypothesis is action orientated, is testable and includes the consideration of methods to engage and improve literacy of those within and external to the health workforce.
