Professional identity formation amongst peer-mentors in a research-based mentoring programme

BMC Medical Education volume 23, Article number: 787 (2023) Cite this article

Abstract

Background

Mentoring plays a pivotal yet poorly understood role in shaping a physician’s professional identity formation (PIF) or how they see, feel and act as professionals. New theories posit that mentoring nurtures PIF by functioning as a community of practice through its structured approach and its support of a socialisation process made possible by its assessment-directed personalized support. To test this theory and reshape the design, employ and support of mentoring programs, we evaluate peer-mentor experiences within the Palliative Medicine Initiative’s structured research mentoring program.

Methods

Semi-structured interviews with peer mentors under the Palliative Medicine Initiative (PMI) at National Cancer Centre Singapore were conducted and triangulated against mentoring diaries to capture longitudinal data of their PMI experiences. The Systematic Evidence-Based Approach (SEBA) was adopted to enhance the trustworthiness of the data. SEBA employed concurrent content and thematic analysis of the data to ensure a comprehensive review. The Jigsaw Perspective merged complementary themes and categories identified to create themes/categories. The themes/categories were compared with prevailing studies on mentoring in the Funnelling Process to reaffirm their accuracy.

Results

Twelve peer-mentors participated in the interviews and eight peer-mentors completed the mentoring diaries. The domains identified were community of practice and identity work.

Conclusions

The PMI’s structured mentoring program functions as a community of practice supporting the socialisation process which shapes the peer-mentor’s belief system. Guided by a structured mentoring approach, stage-based assessments, and longitudinal mentoring and peer support, peer-mentors enhance their detection and evaluation of threats to their regnant belief system and adapt their self-concepts of identity and personhood to suit their context. These insights will help structure and support mentoring programs as they nurture PIF beyond Palliative Medicine.

Peer Review reports

Background

Medical education is tasked with shaping the Professional Identity Formation (PIF) of medical students and physicians (henceforth clinicians), or how they think, feel and act as professionals as they navigate their medical practice [1, 2]. Extant literature [3,4,5,6,7,8,9,10] foregrounds two critical ingredients for the successful nurturing of PIF: the socialisation process and the Community of Practice (CoP) [3]. However, current understanding of these mechanisms remains rudimentary [11].

New insights into mentoring practice at the Palliative Medicine Initiative (PMI), a structured research mentoring program at the National Cancer Centre Singapore (NCCS), may offer a better perspective into the development of professional identities in this aspect of medical education. Indeed, mentoring is a recognised means of developing PIF in medical education. However, before we evaluate PMI experiences, its role in nurturing PIF and its links with CoP and the Socialisation Process, we must foreground our approach with explanations of the terms and theories we will use.

The Palliative Medicine Initiative (PMI)

To begin, the PMI employs a combined novice-, peer- and e-mentoring approach (henceforth CNEP) [12, 13] that sees graduating PMI mentees nominated, recruited, trained, and mentored by senior mentors to support new PMI mentees. Having completed at least one PMI mentored research project and tutored on how to mentor, assess and provide feedback to peers and new mentees, the peer-mentors are re-orientated to the mentoring approach and their roles and responsibilities. Provided with a choice of projects to work on from systematic reviews in ethics, professionalism, communication, PIF, mentoring, thanatology, wellbeing, and reflective practice to qualitative interviews on palliative care, PIF and mentoring, peer-mentors often discuss these projects with the senior mentors involved, ascertaining the alignment of their expectations to work together. Peer-mentors are then provided with access to robust communication channels with the two senior mentors overseeing the project. At this stage, peer-mentors are reacquainted with the PMI’s norms, skills, motivations, and attitudes (henceforth desired characteristics); learning objectives, goals, timelines, professional standards, codes of conduct, roles, responsibilities, expectations, implicit norms, culture, artifacts, sociocultural norms and expectations and legal requirements (henceforth codes of conduct). They are also reintroduced to the current education approaches; the program’s value, support and assessment systems; the settings and stages of training, as well as the formal curriculum (henceforth host organization related facets).

Following their regular bi-weekly online meetings vis-à-vis ad-hoc and informal meetings, peer-mentors make an entry into their mentoring diaries to document their experiences. These entries are privy to only specific members of the administrative staff to safeguard the anonymity and privacy of the peer-mentors whilst ensuring that timely and appropriate support can be provided if any mentoring, mental health, and physical problems are detected.

The PMI also establishes a spiral curriculum for peer-mentors that sees them regularly revisit key training skills and competencies along the training trajectory (Fig. 1). This spiral curriculum is designed on the PMI’s well-established mentoring stages [9]. These include the matching; initial meeting; data gathering and analysis; manuscript writing and submission; and post manuscript submission stages [9]. Each mentoring stage delves deeper into the knowledge, skills, attitudes and experiences of the previous stage. It also brings a new set of competencies to be attained. Moving from one stage to the other demands these competencies be met, creating natural ‘competency-based assessment points’ at transitions from one mentoring stage to the other [9]. These competencies must be met if a peer-mentor is to guide mentees from one stage to the next. The mentoring stages also map out the mentoring trajectory characterising the gradual inculcation of complex skills, knowledge, and competency in communications, relationships, learning, socialisation, collaborations, networking skills, reflective practice, medical humanism, and professionalism that will be employed to guide mentees [2, 11]. The peer-mentor’s mentoring trajectory follows that of the mentee and maps the peer-mentor’s progress in the PMI. Movement along this mentoring trajectory from the periphery of the PMI program towards more significant roles takes a spiral course representing the revisiting of knowledge, skills, and attitudes and achieving the new competencies for each mentoring stage.

These roles are represented by three concentric rings. The centre ring represents the role of a senior mentor whilst the middle and outermost ring denote the roles of the peer-mentor and mentee respectively in the CoP. Progress from one role to the next reflects achievement of the requisite skills and competencies, alongside concurrent changes in perspectives, belief systems, decision making and actions. Shepherding this developmental process is personalised, timely, appropriate, longitudinal, and often holistic mentoring support drawn from the mentoring umbrella, guided by mentoring assessments and provided by the two trained mentors. It is this combination of personalised mentoring support framed around the PMI’s structured approach and the mentoring course mapped out by the mentoring framework that facilitates the shift away from individual self-interests amongst mentees to furthering the interests of the PMI program that practices ‘paying it forward’. Facilitating this spiral course between the circles is a combination of experiential learning [14], graduated mentored immersion in the PMI culture and practice, graded autonomy and allocated responsibility [15, 16], structured revisiting of skills and knowledge to build competence and a developing sense of community, moral reasoning, and reflective judgment [5, 17,18,19,20,21,22,23].

The clearly defined trajectory and expectations set out provide a unique opportunity to study the longitudinal influence of mentoring on the PIF of peer-mentors [8,9,10, 13]. Indeed, ‘exit’ interviews of peer-mentors, along with their feedback and mentoring diaries, allude to changes in the peer-mentor’s values, beliefs, and principles (henceforth belief systems) and their thinking, conduct and practice. It is these findings that have inspired this study into peer-mentor experiences.

In particular, there are two features that are imperative to our study. The first is the mentoring umbrella [2,3,4, 10, 24] which sees an assessment-driven, context- specific, individualised mix of role modelling, networking, coaching, supervision, apprenticeship and traditional concepts of mentoring provided throughout the mentoring program that supports immersive learning and reflective practice. The second is the mentoring structure that includes the physical boundaries of the mentoring program, its curated mentoring environment that actively shapes the hidden and informal curricula [7], and stage-based mentoring [25] within a formal mentoring program overseen by the host organization [26]. The mentoring structure also includes clearly articulated codes of conduct, desired characteristics and host organization related facets [27,28,29,30]; mentored immersion [31] that nurtures experiential learning and builds personalised mentoring relationships; mapped mentoring trajectory [13]; stage-specific competency assessments [9]; longitudinal mentoring support [32]; mentor training programs [10]; and program assessment protocols [26]. Collectively, the mentoring structure guides the mentoring trajectory, assessment, support and program oversight.

The Socialisation Process

The mentoring umbrella plays a key role in supporting the Socialisation Process, or the internalisation of “the characteristics, values, and norms of the medical profession… resulting in an individual thinking, acting and feeling like a physician” [1]. Here, the mentoring umbrella [24, 32, 33], together with longitudinal mentoring support and interactions with peers and mentees over time within the confines of the PMI’s codes of conduct and culture, facilitate the Socialisation Process to shape the peer-mentor’s internalisation of programmatic, speciality-specific, organizational, ethical, legal, professional, socio-culturally relevant values, beliefs, principles and mentoring insights, reflections, experiences, and knowledge.

Community of practice

The Socialisation Process is, in turn, dependent on the presence of an organized, supportive sense of community provided by the PMI through its curated mentoring environment and mentoring structure. This likens the PMI to a Community of Practice (CoP). Indeed, the PMI’s mentoring structure does meet the key features of a CoP as “a persistent, sustaining social network of individuals who share and develop an overlapping knowledge base, set of beliefs, values and history and experiences focused on a common practice and/or enterprise” [34].

With its shared sense of identity, structure, culture and mentoring support, the PMI provides peer-mentors with a holistic and personalised means of inculcating new beliefs, values, principles, insights, and experiences into regnant belief systems within the confines set by the mentoring structure [6, 35, 36]. Together, the features of CoP and socialisation buttress the PIF of peer-mentors as they detect and adjudge the gravity of new beliefs, values, principles, and experiences upon their current belief systems and ensure their response remains within the confines of accepted standards. To advance a more accurate reflection of peer-mentor experiences in the PMI, we adopt the lens of the Krishna-Pisupati Model of Professional Identity Formation (KPM) and the Ring Theory of Personhood (RToP).

The Krishna-Pisupati model of professional identity formation and the ring theory of personhood (RToP)

The RToP builds on the notion that shifts in a clinician’s belief systems change how they see themselves as persons and as professionals. This allows the RToP to map changes in individual belief systems in the clinician’s Innate, Individual, Relational and Societal identities and capture corresponding changes in the Innate, Individual, Relational and Societal rings of personhood (Fig. 2).

Fig. 2
figure 2

The ring theory of personhood

The Innate Identity is derived from the peer-mentor’s regnant spiritual, religious, theist, moral and ethical belief systems within the Innate Ring. The Individual Ring’s belief system revolves around the peer-mentor’s beliefs, values and principles surrounding conscious function and informs the peer-mentor’s thoughts, conduct, biases, narratives, personality, and decision-making processes, thus shaping the peer-mentor’s Individual Identity. The Relational Identity is born of a belief system governing those relationships that the peer-mentor determines to be personal and important. The Societal Identity is shaped by regnant societal, cultural, religious, professional, and legal roles and expectations, and belief systems which inform their interactions with colleagues and acquaintances.

The Individual Identity also manifests in the peer-mentor’s overall identity, balancing the influences of the Innate, Relational and Social Identities. This balancing process shapes and is shaped by the beliefs systems within each domain of personhood. When there is consistency between the beliefs, values, and principles being introduced and the current belief system within the ring or rings of the RToP, there is ‘resonance’. ‘Synchrony’ occurs when current values, beliefs and principles within the ring or rings of the RToP are reprioritised to better fit with the practice beliefs, values, and principles. In contrast, inconsistencies between new and prevailing belief systems lead to ‘dissonance’. Dissonance within one ring of the RToP precipitates ‘disharmony’ whilst ‘dyssynchrony’ manifests from dissonance between rings.

The KPM explores the effects of resonance, synchrony, dyssynchrony and disharmony (henceforth event) on the belief system and PIF (Fig. 3). The KPM suggests that detection of an ‘event’ is determined by the mentee’s ‘sensitivity’ whilst their ‘judgment’ displays the significance of the ‘event’ upon their current belief system. The KPM also captures the notion of ‘willingness’ to address the ‘event’ and the clinician’s ability, experience and opportunity to ‘balance’ possible adaptations in response to the ‘event’ with regnant practical, clinical, personal, sociocultural, professional, academic and organizational considerations culminating in the creation of a context-specific self-concept of identity. The KPM works best within a ‘closed’ or structured mentoring program and a well-surveilled environment to proffer a means of studying the longitudinal effects of a consistent mentoring approach.

It is within these conditions where the PMI functions as a CoP supporting the Socialisation Process and that changes in the peer-mentor’s belief system may be captured by the KPM and RToP that we pose the primary research question, “How does peer-mentoring in a structured mentoring program impact PIF?”. In providing a comprehensive perspective of peer-mentoring experiences in the PMI, we proffer the secondary research questions, “What features of the CoPs and the socialisation process are present in the PMI peer-mentoring experience?” and “What impact does mentoring have on Professional Identity Formation?”.

Methodology

Acknowledging peer-mentoring as a sociocultural construct shaped by individual, psycho-social, academic, professional, clinical, research and environmental considerations, we adopt a Constructivist perspective and a Relativist lens. Accordingly, we adopt a qualitative approach to study the lived experiences of peer-mentors in the PMI. To capture a longitudinal and holistic perspective of peer-mentoring experiences, we employ a semi-structured interview questionnaire and peer-mentoring diaries. We analyzed the data from the semi-structured interviews and diaries using Krishna’s Systematic Evidence Based Approach (SEBA).

Stage 1 of SEBA: Expert advice

In advancing a balanced, accountable and reproducible study and analysis, an expert team consisting of a librarian from the National University of Singapore’s (NUS) Yong Loo Lin School of Medicine (YLLSoM) and local educational experts and clinicians at YLLSoM, National Cancer Centre Singapore, Palliative Care Institute Liverpool, and Duke-NUS Medical School navigated the stages of SEBA (Fig. 4).

Stage 2 of SEBA: Semi-structured interviews

Eligible participants comprised of peer-mentors in the PMI who had completed mentoring programs as mentees and had been subsequently selected, trained and completed PMI mentoring programs as peer-mentors. Purposive sampling was conducted and email invitations containing a participant information sheet and consent form were sent out. The invitations stressed the participant’s rights to privacy and anonymity, as well as their right to withdraw from the study at any point without prejudice. All participants provided written and verbal informed consent.

Individual semi-structured interviews were arranged with each peer-mentor upon return of the endorsed consent forms. These 30–45-min audio-recorded interviews conducted over the Zoom video conferencing platform took place in quiet offices that ensured privacy to facilitate in-depth exploration of personal belief, experiences and practices. The interviews were carried out between February and May 2021 by experienced and trained interviewers, AP and CQWL. As non-clinicians with neither previous interactions nor dependent relationships with the participants, the trained interviewers sent out the email invitations and arranged the meetings. This enhanced the participant anonymity from the research and expert teams. Audio recordings were transcribed verbatim using the NVivo 12 Software, anonymized and their integrity verified.

Ethical considerations

Ethics approval (reference number: 202010–00084 and 202103–00057) was obtained from the Singhealth Combined Institutional Review Board. Informed written and oral consent was obtained from all participants.

Stage 3 of SEBA: Review of mentoring diaries

Peer-mentoring diaries were hosted on Google Forms and were completed by all mentees and peer-mentors in the PMI on an ad-hoc basis between March to December 2021. Mentoring diaries were anonymized by independent research team members not involved in the PMI or the semi-structured interviews for analysis.

Stage 4 of SEBA. Split approach

Three independent teams, each guided by a senior trained PMI mentor, carried out the analysis of the anonymized data. The first and second teams employed Braun and Clarke [37]’s approach to thematic analysis and Hsieh and Shannon [38]’s approach to Directed Content Analysis respectively to analyze the transcripts of the semi-structured interviews. The second team drew categories for the content analysis from Sarraf-Yazdi et al. [11]’s review “A scoping review of professional identity formation in undergraduate medical education”. The third team carried out thematic and content analysis of the peer-mentoring diaries.

At independent and regular online discussions, Sandelowski and Barroso [39]’s approach to ‘negotiated consensual validation’ was used to reach consensus on the codes identified. As the coding process was part of mentor led training and subject to frequent expert team input, Kappa inter-reliability scores were not evaluated.

Stage 5 of SEBA: Jigsaw perspective

This process combined overlapping themes and categories to create themes/categories.

Stage 6 of SEBA: Funneling process

The themes/categories from the mentoring diaries and interviews were combined and funneled to create domains that frame the discussion in Stage 8 [40].

Results

Twelve peer-mentors participated in the study interviews, and a further eight peer-mentors completed the peer-mentoring diaries. Table 1 depicts the demographic information of the participating peer-mentors, including the number of projects undertaken over their course of time in the PMI.

Independent analysis of the interviews with 12 peer-mentors and 8 peer-mentor diaries revealed two domains—the PMI as a Community of Practice, and Identity Formation.

Domain 1. PMI as a community of practice (CoP)

The PMI displays features of a CoP described by existing literature [41,42,43,44,45,46]. Firstly, the PMI exhibits a robust mentoring structure that creates the physical boundaries of the mentoring program, its curated mentoring environment [7], and stage-based mentoring trajectory [25] within a formal mentoring program overseen by the host organization [26]. These facets establish the boundaries of the PMI’s CoP.

The PMI’s strong sense of community, welcoming environment, culture of ‘paying it forward’, and shared belief systems create the CoP’s culture whilst the mentoring umbrella-based support strengthens a peer mentor’s core values of responsibility, teamwork, empathy, respect, integrity and commitment, alongside their shared belief system and identity.

Progress along the PMI’s mentoring trajectory guided by the mentoring umbrella-based support within the clear boundaries of the PMI’s structure and nurturing mentoring environment supports the Socialisation Process. This helps peer-mentors integrate the PMI’s belief system and indeed apply them in the program. This bolsters personal and professional development as peer mentors are encouraged and challenged to adopt new roles and responsibilities.

In toto, the PMI’s sense of community, structured approach, support mechanisms and fostering of personal and professional development solidify its position as a CoP. Table 2 expounds on each key characteristic below.

Domain 2. professional identity formation

Peer mentors exhibit features of PIF in their efforts to attend to resonance, synchrony, dyssynchrony and disharmony. Resonance, for instance, is apparent when peer mentors find that the values, beliefs, principles, and goals introduced in the PMI echo that of their prevailing belief systems. Resonance motivates continued engagement in the PMI and sees peer mentors reshape and reprioritise their regnant values, beliefs and principles to reflect synchrony and inspire action. Here, peer mentors show personal growth in taking on new endeavours not just for their individual self-development, but to find meaning in serving the wider community. However, peer-mentors also encounter obstacles in their PMI journey, alerted by their ‘sensitivity’ to instances of disharmony and dyssynchrony. Disharmony manifests when peer mentors reveal a mismatch between their prevailing skillsets and new responsibilities whilst managing ‘difficult’ mentees who miss deadlines or produce inadequate work heightens dyssynchrony.

Dyssynchrony, disharmony, resonance, and synchrony may arise as an acute ‘event’, such as the rejection of a white-listed journal submission (P10) or dealing with ‘difficult’ mentees (P11). The precipitating ‘event’ may also be a slow process simmering or persistent issues such as dealing with a lack of ‘confidence’ (P5) and self-belief (P2), contending with changing perspectives of oneself and roles (P2), balancing competing demands on time and maintaining a work-life balance (P3).

How and if dyssynchrony, disharmony, resonance, and synchrony are to be addressed is determined by the peer-mentor’s ‘judgement’ that accords attention, significance and urgency to the issue. Often, ‘judgement’ is perceived as a matter of goal setting, prioritising tasks, time and roles and managing expectations. Upon determining the magnitude of the situation, the peer mentor’s motivation to make adaptations to their self-concepts of identity pivots on their ‘willingness’. This is depicted as part of the peer-mentor’s responsibility (P6), accountability (P11), goals (P7) and aspirations (P4).

Peer mentors also exhibit ‘balance’ in determining the changes to be carried out and prioritised in making adjustments to their self-concepts of identity. The process of balancing is also impacted by the speed in which events occur, the peer-mentor’s ‘sensitivity’, ‘judgment’ and ‘willingness’ and if there are further changes in the peer-mentor’s circumstances. This then culminates in peer mentors practicing ‘identity work’ that sees the integration of new work practices, values, beliefs and principles, ‘sensitivity’, ‘judgment’, ‘willingness’ and ‘balance’ to create context-specific self-concept of identity.

Table 3 brings together the features of PIF identified in the PMI in more detail.

Stage 7 of SEBA: Discussion

This study reveals that a structured program like the PMI does act as a CoP supporting the socialisation process capable of nurturing PIF amongst peer-mentors. Through the lens of the KPM and RToP, it is possible to appreciate the impact of resonance, synchrony, dyssynchrony, and/or disharmony on belief systems and its effects upon the conduct and practice of peer-mentors as they progress along the mentoring trajectory set out (Fig. 5).

The trajectory of peer-mentors in CoPs

Full size image

Dependent on the peer-mentor’s individual experience, capabilities, goals, abilities, and availabilities, it is common that the course taken by new peer-mentors deviates from the ideal (blue line). Here, the role of the mentoring umbrella helps them stay on course and as close to the ideal trajectory. However, as the data suggests, changes in the peer-mentor’s personal, psycho-social, financial, clinical, research, academic, practice and/or psycho-emotional situation may lead to a significant ‘event’. Here, the presence of regular stage-based assessments help direct further personalised and appropriate support to peer-mentors. If effective, these interventions bring the peer mentoring trajectory back towards the ideal trajectory. It is posited that with these interventions, peer-mentors will eventually achieve their goals.

Our data also reveals a further reason for deviations from the ideal mentoring trajectory. Peer-mentors appear to be simultaneously involved to varying degrees in different roles in concurrent projects. Whilst concurrent participation in multiple mentored programs within the PMI may impact progress in their primary project, evidence of multiple frequently overlapping programs within the PMI casts the PMI as a collection of projects, each functioning as a CoP. This implications of a “complex landscape of different communities of practice” invites the idea of the PMI being a Landscape of Practice (LoP) [27, 46,47,48,49,50,51,52,53,54,55,56] and raises a number of considerations.

For peer-mentors involved in several concurrent projects (multi-membership), often in different capacities in a LoP, ‘events’ have wider connotations and are subject to wider influences. Here, subtle differences even amongst projects built on a common PMI belief system may be problematic due to possible differences in the support and advice provided by various mentors. This underscores the need for longitudinal and holistic evaluation of peer-mentor’s progress.

On the surface, being a LoP underlines the importance of the PMI, ensuring consistency in the culture, goals, belief systems and structure within projects/CoPs. It also stresses the importance of ensuring that PMI mentors are effectively trained and supported, and that there is alignment of expectations; timely, stage-based and appropriate assessments; oversight; and seamless support across the PMI. On a deeper level, however, it does shift the manner in which progress is viewed within the PMI. Indeed, it may be suggested that progress within multiple PMI projects may be viewed as the peer-mentor’s overall progress towards refining their PIF (Fig. 6).

Updating the Krishna-Pisupati’s theoretical model of professional identity formation

With the KPM increasingly proposed as an evidence-based approach to better understand PIF in mentoring and potentially in medical education, ensuring that the KPM is clinically relevant is critical. The notion of the PMI being a LoP thus inspires a change in the manner that we view Krishna-Pisupati’s theoretical model (Fig. 7).

The updated Krishna-Pisupati framework for PIF in mentoring

Full size image

Situated within the LoP which also captures the wider contextual and environmental considerations, the advanced KPM is still focused upon the PIF of an individual. As a result, there remains due acknowledgment of the influence of the individual’s narratives. ‘Sensitivity’, ‘judgment’, ‘willingness’, and ‘balance’ leading up to the creation of working hypothesis for a context-specific identity that can straddle all the PMI projects now also considers the peer-mentor’s ability and responsiveness, as well as the notion that events need not be singular nor from one source, but from multiple sources. Events may also exhibit differing levels of importance and exigency. This underscores the importance of continued guidance and support of peer-mentors as they rank ‘events’ in terms of importance and significance.

Experimenting with the working hypothesis or ‘adapted’ professional identity and belief systems is guided by available support, culture and structure of the CoPs and the LoP, as well as regnant codes of practice, boundaries, expectations, roles and responsibilities set out by the LoP and CoPs.

Limitations

Although insightful, this qualitative approach built upon the RToP has not been validated and is subject to bias interpretations by the authors. Moreover, although supplemented by mentoring diaries, the use of interviews as the primary source of data in this study remains as ‘snapshots’ or retrospective accounts that are susceptible to recall bias. There are also limitations due to the small sample size and the limit of the depth of the data collected.

Whilst the categories drawn from directed content analysis emphasised the features of CoPs in the PMI and complemented the themes identified in Identity Formation, the Split Approach and Funnelling Processes are time and resource-heavy and could threaten the sustainability of the study. Similarly, use of independent team analysis and the Split Approach may not have fully attenuated the risk of bias.

Conclusion

This study suggests that a structured mentoring program can shape professional identity in a consistent manner as long as there is due consideration for the needs of the peer-mentor and the influence of environmental factors. The impact of environmental factors is multiplied when multi-membership is present and underlines the need for portfolio use that will not only assess their competency, but their PIF and promote the use of reflective practice and mentoring diaries. This then must be an area for future study.

Similarly, whilst this study will be of particular interest to program designers, host organizations and senior mentors, it does reiterate the need for host organizations to ensure careful stakeholder selection, training, assessment, and support; effective alignment of expectations; longitudinal support and assessment of the mentoring, communication, assessment, and oversight mechanisms within the program; and careful curation of the mentoring culture and structure. This underlines the need for effective program evaluations. These gaps in appraisals ought to be the focus of future studies as we plan to extend the PMI beyond Palliative Medicine.
