In many developed-world countries, attempts to enhance healthcare quality, effectiveness, and efficiency have shifted away from top-down techniques and toward measures that rely more on frontline employee participation and empowerment. Various clinician-led, network-based initiatives in Europe and elsewhere (Addicott et al., 2007; Van Wijngaarden et al., 2006) represent attempts to delegate responsibility for improving health-service provision to staff at the 'coal face,' who are better positioned than senior managers and policymakers to transform services in a sustainable way. This trend has sparked debates in medical sociology and related fields about the changing nature of healthcare work, including professional boundary reconfiguration (Nancarrow and Borthwick, 2005), professional identity management (Waring, 2011), and shifts in authority and accountability in changing organizational forms (Martin, 2009a). In this environment, attempts to empower frontline personnel with the capacity, skills, and legitimacy to drive changes in healthcare organization are particularly noteworthy. In particular, there have been significant initiatives to improve clinical staff's 'leadership ability' (Koteyko and Carte 2008). A variety of programs to encourage and support leadership in healthcare have been established in the United States, the United Kingdom, and internationally, similar to other public services. Leadership is increasingly viewed as a skill that should not be limited to senior executives at the top of companies, but should be embraced by employees at all levels (Hartley and Allison, 2000). Managers, clinicians, and even patients are encouraged to be 'leaders' by demonstrating good practice and influencing their peers in order to accomplish change that is accepted by all (Martin a Learmonth, 2012). However, people charged with exercising leadership encounter practical challenges, particularly in public service environments such as healthcare, where policy imperatives, professional divisions, and bureaucratic systems can obstruct staff's capacity to lead across boundaries and up hierarchies (Coope et al., 2012; Martin, 2009a). As a result, the concept of 'distributed leadership,' as espoused in management literature and operationalized by managers and policymakers, has received a lot of flak (Currie et al., 2011; Martin and Learmont 2012; O'Reilly and Reed, 2010). Policymakers are increasingly emphasizing the need for leaders at every level of service delivery, driving change across organizational and professional boundaries, to address 361 social issues that are not amenable to improvement through the actions of a single profession, organization, or even sector. Martin and Learmonth (2012) studied the evolution of leadership rhetoric in important government policy documents in the United Kingdom, identifying both an increasing emphasis on leadership in general and a shift in focus towards the role of frontline, clinical leaders throughout the health professions. Recent policy documents, such as the NHS Next Stage Review (Secretary of State for Health, 2008), call for all clinicians (explicitly include non-medical as well as medical professionals) to be "practitioners, partners, and leaders" (2008: 14; see also ch. 5 passim). Despite being the product of a different government and heralding significant changes in NHS organization (in England), the recent white paper Equity and Excellence maintains this emphasis on clinicians' front-line leadership, promising to 'liberate professionals and providers from top-down control' (Secretary of State for Health, 2010: 27): 'clinicians will be in the driving seat and 'clinicians will be in the driving seat and 'clinicians will be in the driving seat and 'clin (2010: 51).
