A rapid realist review on leadership and career advancement interventions for women in healthcare.

Women represent 70% of the global health workforce but only occupy 25% of health and social care leadership positions. Gender-based stereotypes, discrimination, family responsibilities, and self-perceived deficiencies in efficacy and confidence inhibit the seniority and leadership of women. The leadership inequality is often compounded by the intersection of race and socio-economic identities. Resolving gender inequalities in healthcare leadership brings women's expertise to healthcare decision making, which can lead to equity of healthcare access and improve healthcare services. With the aim of enhancing women's advancement to leadership positions, a rapid realist review (RRR) was conducted to identify the leadership and career advancement interventions that work for women in healthcare, why these interventions are effective, for whom they are effective, and within which contexts these interventions work. A RRR ultimately articulates this knowledge through a theory describing an intervention's generative causation. The Realist and Meta-narrative Evidence Syntheses: Evolving Standards (RAMESES) for conducting a realist synthesis guided the methodology. Preliminary theories on leadership and career advancement interventions for women in healthcare were constructed based on an appraisal of key reviews and consultation with an expert panel, which guided the systematic searching and initial theory refinement. Following the literature search, 22 studies met inclusion criteria and underwent data extraction. The review process and consultation with the expert panel yielded nine final programme theories. Theories on programmes which enhanced leadership outcomes among women in health services or professional associations centred on organisational and management involvement; mentorship of women; delivering leadership education; and development of key leadership skills. The success of these strategies was facilitated by accommodating programme environments, adequacy and relevance of support provided and programme accessibility. The relationship between underlying intervention entities, stakeholder responses, contexts and leadership outcomes, provides a basis for underpinning the design for leadership and career advancement interventions for women in healthcare.
