Background
The number of females having graduated from medical schools over the last 20-30 years is now close to 50% in many regions around the world. Hence it was anticipated that this would have already translated into an increasing number of female doctors attaining the full range of higher academic and or leadership positions across all of the relevant subspecialties [
3]. However, it has become increasingly apparent particularly over the last decade or so that despite these increased numbers of female medical graduates that this has not translated into the same proportion of females being employed across all of the medical and surgical subspecialties, nor were they making it into the higher leadership positions for a number of the relevant academic endeavours’ (
Table 1).
It has also become apparent that despite there being more females numerically wise in academic medical positions in the United States (US), proportionally fewer females were ending up in the higher leadership academic type positions [
4]. By 2019 41% of the full-time faculty in the US were female, whilst 18% of the departmental chairs were female. A systematic review of the then available published literature from the US, Canada and the United Kingdom also revealed that organizational type barriers were also being increasingly identified as contributing to barriers the career progression of female surgeons [
5]. The barriers identified included - an organizational type of culture which was a hindrance to the females, as well as work/family conflict affecting the females more than the males.

By 2018 although there had been a steady increase in the overall numbers of females in surgical disciplines within the US, the numbers were not uniform across all of the subspecialties [
7]. The lowest percentage of females were found to be in Cardiothoracic surgery (16%) whilst the highest percentage were in Obstetrics and Gynecology (63.3%). Similar discrepancies were also revealed in data from Spain where there were no females employed as Cardiothoracic surgeons in the healthcare system, whereas for Ophthalmology there was close to gender parity. In addition, the males were still far more likely to be in leadership positions across all of the surgical and medical specialties by a factor of just over 3 to 1 [
8]. When academic related activities were further looked into including for example the authorship of manuscripts published in prominent US medical journals [
4], females were less likely to be either first or senior authors for a range of medical journals and were also less likely to be invited to submit guest editorials [
4]. Similar results were reported for a Brazilian surgical journal [
9], where 25% of the first authors were female compared to 21.8% of the last authors being female. Closer examination of the membership of the editorial boards of surgical journals in the US, Europe, and Latin America as well as medical and surgical journals in Australasia [
10,
11,
12,
13], also revealed similar discrepancies. The proportion of editorial board members who were female ranged from 13- 33.9%, whilst in comparison 4.8 - 22% of the Chief Editors were female [
10,
11,
12,
13]. Plus, a number of journals were identified where there were either no females on the editorial board at all, or there were no females in either an Associate or Chief editor position, confirming that there is significant variation in the gender ratios for who is being recruited to serve in all of these positions. Similar demographic data have been published for surgical conferences where the percentages of female speakers varied from 18.9-58.5%, depending on the actual subspecialty which correlated with whether or not there were females on the planning committee [
14]. An even larger data set for the proportion of female speakers for 98 medical meetings involving 20 specialties between 2017-2018 revealed that 30% of the speakers were female but that concerningly 36.6% of the panels were all male [
15]. Again, there was a positive correlation demonstrated between the proportion of women on the planning committee and the numbers of female speakers.
Gender ratios of the Liver Transplant Workforce
In Spain although 56.3% of the Hepatology workforce are female, only 15% of the high-ranking leadership type positions are held by females [
3,
16]. In comparison in the United States in the parent specialty of gastroenterology, although there are proportionally fewer females (15%), they do tend to be more likely to undertake an academic career (40%), but are also less likely to be found in leadership positions either within the institutions where they are employed or at the level of national societies [
4,
17].
When it comes to other academic type activities such as publishing in the hepatology related scientific journals there are data for the genders of the first and second authors of published manuscripts and of the invited editorials/reviewers of liver related publications [
6,
18]. It appears that female authors regardless of their career stage are less well represented (ranging from 20.3% of the senior authors being female through to 34.9% of the first authors being female). In fact, there was some evidence that the percentage of female senior authors may have diminished over a 2-year period (2014-2015) from 32.6% to 20.3%. Data have also been published on the ratios of females to males for both the chief editors’ positions (7.7% were female), along with the wider editorial boards (17.4% were female) of some of the high impact gastroenterology and hepatology journals [
7,
19]. There are also published data highlighting the discrepancies in the gender composition of various chief editors’ positions (4-17% were female), for a range of solid organ transplantation journals [
8,
20].
It also appears that proportionately fewer female attendees (19%) deliver presentations at hepatology related professional scientific meetings, which mirrors the proportion of both the session convenors and panel moderators who are female (20%) [
2]. Whereas in Spain where on average 60% of the presenters of abstracts at the relevant scientific meetings are female, in comparison only 19% of the invited speakers or the session moderators are female [
3,
16]. Mention has been made of this type of gender disparity also extending to the awarding of research grants [
9,
21], including from major research funders within the United States. However currently there is a lack of published granular data pertaining to the awarding of research grants in other regions of the world particularly when it comes to research in the various liver transplantation related disciplines. Hence it seems on balance that there may be barriers to the females also securing the types of other senior roles and or related positions which are associated with both career advancement as well as attaining the higher levels of academia in Hepatology. This is commonly known as the pipeline effect [
10,
11,
22,
23], where women are lost from every level of the academic career ladder.
As to understanding what might also be happening around the rest of the world when it comes to the gender ratios of the liver transplant workforce up until, relatively recently there was a paucity of data. This was partially rectified when the results of data collected from 243 transplant centres were published via a subcommittee of the International Liver Transplantation Society (ILTS) [
5,
24]. This revealed that only 32/243 centres (13.2%) had either a female chief of Hepatology or of Liver Transplant Surgery. In addition, 31.9% of the responding hepatologists were female compared to 18.2% of the transplant surgeons [
5]. However, the percentages of females who were in a leadership position varied according to practice location, with there being no females in leadership positions in either Australia or Canada whilst the highest proportion were based in the United States (18 %). This is similar to 17% of the Chiefs of Transplant Surgery across the United States being female [
25], although this percentage may not be the same for the heads of the clinical liver transplant programmes. The ILTS survey also revealed that the percentage of liver transplant programs without either a female hepatologist or a female liver transplant surgeon also varied from region to region with the lowest rates seen in Asia (57% and 77% respectively). However, the percentage of the total number of female members of the ILTS (26.4%), was similar to the percentage of females who were holding leadership positions within the ILTS (26.9%), which the authors partly attributed to ongoing efforts to promote females into leadership positions within the society [
24]. To date this is the most comprehensive set of data that has become available despite the fact that not all of the transplant centres were captured and not every liver transplant professional is a member of the ILTS. Mention has been made of more comprehensive data capture methods and reporting being used in order to better understand what the true extent of the various gender disparities may be [
24].
Recommendations for addressing the gender disparities
It is apparent that a number of generic type of recommendations for corrective measures have steadily emerged via a number of previous publications (
Table 2), many of which pertain to all of the relevant stakeholder organizations in healthcare. The first step involves recognising that there may be an ongoing gender disparity of the relevant workforce within the organization and that this disparity may be more marked for the higher leadership positions. The next step involves developing and implementing policies that encompass a range of corrective actions, including both sponsoring female professionals as well as removing barriers to career progression. This may also require implementation of specific context relevant policies for example around both remuneration and family leave. A lack of adequate family leave entitlements has being previously mentioned as a barrier to career progression for females [
5,
24,
26]. These types of measures need to be implemented across the wider healthcare organizations as the relevant issues are generic and also apply to the rest of the female medical and surgical workforce. Plus, it is increasingly being recognised that isolated stand-alone sponsorship and/or mentorship initiatives on their own may not result in more females either being employed in the relevant subspecialties and/or attaining higher leadership positions [
1,
23,
26].
When it comes to the relevant scientific journals, this may require a range of specific corrective actions. This includes ensuring that more females are recruited onto the wider editorial board, as well as facilitating more females attaining either the Chief editor or the Associate editor role [
11,
12,
13,
19]. Attention also needs to be paid to the gender ratios of the authors for invited editorials and or perspective type manuscripts. In addition, for transparency purposes it would be useful if the relevant scientific journals could both track and publish the data on the gender ratios of both first and senior authors as well as for the invited authors.
There are also connotations for all of the relevant professional stakeholder organizations of which there are many around the world. Several of the larger international professional solid organ transplant type organizations have already undertaken to move from having formal statements on equity and diversity to understanding what is actually happening at the level of the workforce. The ILTS has already been mentioned, however more recently the European Society for Organ Transplantation (ESOT) formally surveyed its membership on their views on diversity and equity. There was significant support for the society moving towards prioritizing a number of ongoing efforts to embed equity and diversity initiatives into all of its professional activities [
1]. This involves undertaking a number of deliberate actions to ensure that there is gender equity and diversity is being achieved across the range of leadership positions within ESOT. There was also support for action pertaining to achieving both equity and diversity in the awarding of research grants as well as for all other awards being sponsored by the society.
All of these aforementioned measures are important because with liver transplantation being a subspecialty within wider healthcare systems and/or organizations around the world, there also needs to be an ongoing focus on the relevant wider system level actions. These all have a number of connotations particularly for the leadership governance of all of the stakeholder organizations that are listed. Along with implementing a range of actions, equally important will be the capturing and reporting of the relevant data elements. This is essential so that a greater understanding can be obtained of not only where the ongoing issues might lie but also whether progress is being made in reducing the current documented gender disparities for the liver transplant workforce.
