EI has been conceptualized through different theoretical models with distinct views on emotional competencies and their role in human adaptation. The ability model proposed by [30], defines EI as a set of cognitive capacities for processing emotional information, including the perception, facilitation, understanding, and regulation of emotions. From this perspective, EI is a form of functional intelligence that can be measured through performance tasks.

In contrast, trait models view EI as a set of stable emotional dispositions closer to personality, reflecting consistent tendencies in emotional perception and response over time. Mixed models integrate emotional competences with motivational, social, and behavioral factors, including empathy, adaptability, and interpersonal skills ([25]; [31]).

Despite these conceptual differences, contemporary literature points to a gradual convergence: EI is increasingly seen not only as an individual characteristic but as a functional system of adaptation relevant in complex contexts with high emotional and cognitive demands ([7]; [38]).

The link between EI and psychological adaptation is particularly evident in emotional regulation. Resilience, understood as the capacity to maintain or restore adaptive functioning in the face of adversity, depends on how individuals regulate emotional states under stress.

Recent meta-analytic evidence shows a robust association between EI and resilience among healthcare professionals and students ([17]), suggesting that EI functions as an active mechanism of adaptation in high-demand contexts.

According to [38], emotional regulation involves modulating which emotions individuals experience, when they occur, and how they are expressed. Strategies such as cognitive reappraisal have been consistently associated with better psychological outcomes, greater emotional stability, and lower vulnerability to burnout. Thus, emotional regulation is the central mechanism of EI through which emotional abilities are translated into adaptive responses.

The proposed neurocognitive basis of EI involves the interaction between brain systems involved in the detection, evaluation, and regulation of emotional stimuli.

The amygdala plays a central role in detecting emotionally salient stimuli, especially those linked to threat or uncertainty, and is a key marker of automatic emotional response and stress sensitivity ([23]). In contrast, the prefrontal cortex, particularly the dorsolateral and ventromedial regions, supports executive control, decision-making, and top-down regulation of emotion, thereby modulating amygdala activity and promoting more adaptive responses.

The effectiveness of this modulation depends on functional interactions between subcortical and cortical regions. [4] show that effective emotional regulation is associated with amygdala-prefrontal connectivity. This finding is relevant to the present framework because emotional regulation constitutes a central component of EI; however, it should not be interpreted as direct neurobiological evidence of EI in healthcare professionals. Rather, amygdala-prefrontal connectivity is considered here as a plausible explanatory pathway through which emotion-regulation processes associated with EI may support adaptation to stress.

Evidence on early adversity further illustrates the sensitivity and plasticity of these corticolimbic circuits. [13] showed that early maternal deprivation was associated with altered developmental patterns of amygdala-prefrontal connectivity, while more recent evidence has linked early social adversity to alterations in functional connectivity involving the amygdala and prefrontal regulatory networks ([19]; [23]). These findings concern adversity and neural development rather than EI itself, but they provide complementary neurocognitive context for understanding how emotional-regulation systems may be shaped by experience and subsequently contribute to adaptation under stress.

Beyond these structures, emotional regulation involves large-scale brain networks, including the Salience Network (SN), the Central Executive Network (CEN), and the Default Mode Network (DMN) ([2]; [32]; [43]). The SN detects relevant stimuli and supports transitions between cognitive states, while the CEN supports cognitive control and emotional reappraisal. Their interaction allows flexible adaptation to complex and emotionally demanding contexts.

Recent literature highlights the role of neural plasticity in these systems. Early stress can alter functional connectivity between limbic and prefrontal regions, with lasting effects on emotional regulation. [19] and [23] show that early adversity is associated with changes in emotional and executive network connectivity, reflecting both vulnerability and capacity for functional reorganization across development.

Interventions focused on emotional competencies provide additional evidence of this plasticity. A study by [22] indicates that EI training can improve stress regulation and performance in high-demand contexts. Complementarily, [41] shows that EI interventions in nursing professionals are associated with reduced stress and improved quality of care.

The integration of these levels of analysis allows EI to be conceptualized as an adaptive regulatory system operating at the intersection of biological, cognitive, and behavioral processes. This can be understood as an “Invisible Neurocognitive Shield”, in which EI does not eliminate stress but modulates its processing through underlying neurocognitive circuits.

At the biological level, the model incorporates amygdala-prefrontal connectivity and network flexibility as proposed neurocognitive pathways relevant to emotional regulation, rather than as established neural markers of EI. At the psychological level, EI-related processes appear as emotional awareness, cognitive reappraisal, and attentional control. At the behavioral level, these processes may support performance and adaptation under pressure.

This conceptualization is particularly relevant in high-demand contexts such as health systems. Burnout, recognized by [52] as an occupational phenomenon, has been widely documented among health professionals and is associated with poorer quality of care ([21]; [27]; [47]). Although organizational factors play a decisive role, individual emotional regulation also shapes how stress is experienced and managed, reflecting an interaction between structural conditions and psychological mechanisms ([44]; [51]). More recently, [12] showed that higher EI is associated with lower burnout and lower intention to leave, reinforcing its protective role in clinical contexts.

In summary, EI should be understood as an integrated neurocognitive system linking biology, cognition, and behaviour through emotional regulation. Operationalized in the “Invisible Neurocognitive Shield” model, this framework provides the theoretical basis for the empirical analysis developed in the following chapters. Its relevance lies in its manifestation in real contexts, especially in complex organizational environments such as health systems, where emotional demands are continuous and contextually determined.

Figure 1 presents a conceptual model that integrates evidence from distinct literatures. The amygdala-prefrontal pathway represents a proposed neurocognitive explanation for emotional regulation rather than a directly demonstrated pathway linking EI to burnout or clinical performance.

Emotional labor constitutes a structural and cross-cutting dimension of healthcare systems, although it often remains invisible within traditional metrics of organizational performance. Since Hochschild’s classic formulation ([18]), emotional labor has been understood as the process through which individuals regulate and adjust emotional expression to comply with implicit or explicit institutional rules. In the health sector, this requirement is continuous and embedded in the delivery of care.

For physicians, emotional labor is closely linked to managing clinical uncertainty, communicating adverse diagnoses, and making decisions under high ethical and cognitive pressure. This combination of decisional load and emotional demand creates a stress profile strongly associated with burnout, a phenomenon widely documented in the contemporary literature ([8]; [27]). Evidence from [44] reinforces that physicians’ well-being is shaped not only by individual factors but also by the interaction between systemic demands and working conditions, with implications for adaptation and emotional regulation.

For nurses, emotional labor is continuous, relational, and intensive. Prolonged contact with suffering, pain, and human vulnerability requires real-time emotional regulation, often without adequate recovery periods. This is the group in which the literature most consistently links higher EI with better occupational outcomes. Recent studies show that higher EI is associated with lower burnout, lower intention to leave, and higher perceived quality of care ([12]; [41]). These findings suggest that EI functions as a factor of emotional stabilization in high-affective-exposure contexts.

For operational assistants and support workers, emotional labor is often less recognized, but it is equally intense. This group is frequently exposed to extreme suffering, patients’ physical dependence, and direct interaction with family members in critical emotional states. The lack of formal recognition of this labor contributes to its institutional undervaluation, despite its cumulative psychological impact, aligning with literature on the implicit devaluation of emotionally demanding roles in organizations ([15]; [18]).

For administrative and institutional support professionals, emotional labor is expressed through conflict management, mediation between users and the healthcare system, and continuous exposure to organizational frustration. Although less visible, this type of emotional regulation is highly relevant to service functioning and to organizational dynamics that shape institutional communication and the overall care experience ([9]; [46]).

The integrated analysis of these different professional profiles suggests that emotional labor is unevenly distributed within healthcare systems. It is important to note that this professional differentiation is derived from narrative synthesis of separate bodies of literature addressing each occupational group independently, rather than from studies employing a common EI measure across physicians, nurses, support staff, and administrative personnel within the same sample. As such, these profiles constitute working hypotheses grounded in emotional-labor theory ([18]) rather than empirically confirmed comparative findings, and they warrant direct testing in future multi-group designs. A further note on the evidentiary basis: a systematic review by [26], synthesizing EI-related evidence across multiple healthcare professions, reported both similarities and differences across occupational groups, but also identified substantial heterogeneity in the underlying evidence—with comparative data more consistently available for physicians and nurses than for support and administrative personnel. This variability implies that EI cannot be seen as a generic competence, but rather as an adaptive system that responds to different profiles of emotional demand, in line with approaches that integrate individual and contextual factors in understanding burnout and professional well-being ([27]; [44]). This functional heterogeneity constitutes the starting point for the analysis of the global evidence patterns presented in the following section.

From a psycho-pedagogical and organizational perspective, this heterogeneity reinforces the importance of continuous development of emotional competencies. Recent evidence from ([25]; [50]) suggests that self-regulation, volitional control, and cognitive-emotional management are associated with performance in high-demand contexts, highlighting a relevant link between academic training and professional functioning.

Furthermore, the literature on burnout in healthcare professionals shows that stress not only affects the individual but also directly compromises the quality of the care system. [21] show that high levels of burnout are associated with poorer quality of care, higher risk of clinical error, and lower patient safety, reinforcing the systemic nature of the problem.

Within this framework, EI emerges not only as an individual competence but as an organizational mechanism for regulating emotional labor ([15]; [18]). Its relevance becomes particularly evident when integrated with the neurocognitive models discussed in the previous chapter, in which emotional regulation functions as a mediator between environmental stimuli and adaptive behavioral response.

Thus, emotional labor should be understood as the point of contact between organizational structure, emotional demand, and individual neurocognitive capacity, constituting the first level of application of the conceptual model of EI as an integrated regulatory system, whose expression in different contexts will be analyzed in the following section.

section, highlighting how emotional labor, burnout, resilience, and performance intersect across healthcare roles.

Empirical evidence on EI in healthcare contexts reveals a consistent pattern of convergence across different geographical regions, despite the structural, cultural, and organizational diversity of health systems. This suggests that EI is not merely a culturally conditioned construct, but a functional mechanism of adaptation with a relatively universal expression in high-emotional-demand contexts ([12]; [27]).

In the United States, longitudinal studies by [45] show a progressive worsening of burnout among healthcare professionals over the last decade, linked to organizational pressures and persistent emotional overload. Complementarily, [51] show that resilience and EI-related competences act as protective factors, partially mitigating occupational stress and improving adaptive capacity in complex environments.

In the European context, the literature shows similar trends. [8] identifies burnout as a structural occupational phenomenon with a direct impact on the sustainability of health systems, while systematic reviews such as [47] show a consistent association between professional burnout and poorer quality of care. These findings reinforce that emotional management is not merely an individual variable, but a systemic determinant of clinical performance.

In Asian contexts and in health systems in transition, this pattern is also observed, although shaped by cultural variables such as institutional hierarchy, norms of emotional expression, and power distance. In these settings, EI appears to play an important role as a mechanism of cultural adaptation, allowing emotional expression to be adjusted to social norms without compromising relational or clinical effectiveness ([12]; [17]).

In Latin American countries and the Global South, despite the structural limitations of health systems, the evidence points in the same direction: high emotional demand coexists with greater vulnerability to burnout, but also with protective effects associated with emotional regulation and EI. This consistency suggests the existence of shared underlying mechanisms ([17]; [21]; [47]).

From a neurocognitive perspective, this convergence can be explained by the functional universality of the circuits involved in emotional regulation. The interaction between the amygdala and the prefrontal cortex is central to stress-response modulation and is widely replicated across populations and cultural contexts ([1]; [38]; [51]). Effective emotion regulation is consistently associated with functional connectivity patterns reflecting efficient amygdala-prefrontal modulation ([2]).

This pattern is complemented by large-scale brain network models, in which the salience network and the central executive network play key roles in detecting relevant stimuli and supporting cognitive control. [4] propose that these networks operate as integrated dynamic systems involved in the construction of emotional meaning, while [43] highlights the role of the salience network in detecting salient stimuli and coordinating transitions between cognitive states.

Taken together, these neurocognitive findings and the broader evidence on EI and occupational outcomes provide a plausible explanatory pathway for understanding how EI-related regulatory processes may operate under stress ([4]). However, these neurocognitive findings should be interpreted as complementary evidence rather than as direct evidence that EI, burnout, resilience, and professional performance are mediated by amygdala-prefrontal connectivity in healthcare professionals. The cited neuroscience literature primarily addresses emotional regulation, stress, or adversity, whereas the evidence concerning EI and occupational outcomes derives from separate healthcare studies.

The integration of these two bodies of evidence therefore supports a proposed explanatory pathway rather than an established neurobiological mechanism: EI-related emotional-regulation capacities may contribute to adaptive responses under pressure, while amygdala-prefrontal regulatory processes provide a plausible neurocognitive substrate for such regulation ([4]; [39]). This interpretation preserves the multilevel nature of the “Invisible Neurocognitive Shield” model while avoiding the assumption that the neural, psychological, and occupational variables have been demonstrated jointly within the same empirical samples.

Thus, the global convergence of the evidence not only supports the relevance of EI in healthcare settings but also points to a functionally conserved neurocognitive architecture underlying emotional regulation, modulated by cultural and organizational factors without being fundamentally determined by them.

The relationship between EI, psychological resilience, and professional performance is a central theme in contemporary healthcare literature, reflecting a shift from descriptive approaches to explanatory and mechanistic models. Rather than an isolated trait, EI can be understood as a functional system that may contribute to the regulation of environmental stress and support emotional regulation and behavioral adaptation.

Psychological resilience, defined as the capacity to maintain or regain adaptive functioning in the face of adversity ([5]), is consistently identified as one of the main outcomes associated with EI. [17] provide robust evidence of a positive association between EI and resilience in health professionals and students, suggesting that EI not only correlates with adaptation but also contributes to its functional development over time.

This effect can be interpreted in light of the neurocognitive framework presented in the previous chapter, in which efficient emotional regulation depends on interactions between amygdala reactivity and top-down prefrontal control ([1]; [38]). Within the present review, this relationship is proposed as an explanatory pathway rather than as an empirically established neural mechanism of EI. Evidence on amygdala-prefrontal connectivity indicates that these circuits are involved in emotional regulation and adaptation to stress ([4]; [39]), whereas evidence linking EI to resilience and occupational outcomes comes from separate studies of healthcare professionals. Accordingly, higher EI may plausibly support more effective emotional regulation, but the available literature does not establish that this association is directly mediated by amygdala-prefrontal connectivity in the same clinical samples.

In the domain of burnout, the evidence is especially consistent. [12] show that higher EI is associated with lower burnout, lower intention to leave, and greater emotional stability in nursing professionals. These findings align with [27], who conceptualize burnout as a multidimensional phenomenon arising from the interaction between chronic work demands and available psychological resources, with EI representing an important resource for mitigating these effects.

From an organizational perspective, [21] show that burnout is not merely an individual phenomenon, but a systemic factor that directly affects quality of care, patient safety, and institutional efficiency. In this sense, EI can be conceived as a psychological resource operating not only at the individual level but also as an indirect moderator of organizational outcomes.

The relationship between EI and professional performance may involve several interconnected mechanisms. First, effective emotion regulation reduces the cognitive load associated with stress ([6]; [29]), freeing executive resources for complex clinical tasks ([38]; [39]). Second, it promotes affective stability in uncertain contexts, improving decision-making under pressure ([20]; [40]). Third, it facilitates the quality of interpersonal interactions, which is especially relevant in multidisciplinary teams ([14]; [43]).

Experimental and applied evidence reinforces these mechanisms. [22] report that EI training interventions can significantly improve stress regulation and performance in high-demand contexts, suggesting that these processes are at least partly trainable and may involve neuroplasticity mechanisms. Likewise, [41] reports that EI development programs in nursing are associated with reduced perceived stress and improved quality of care.

These results are particularly relevant when integrated into the “Invisible Neurocognitive Shield” model presented in the previous chapter. Within this framework, EI is conceptualized as a regulatory system that may contribute to stress adaptation and help explain the relationship between resilience and performance ([16]; [39]).

It is also important to emphasize that these pathways are dynamic and bidirectional rather than linear. Repeated practice in emotional regulation may be associated with adaptive changes in neurocognitive systems involved in executive control, potentially supporting more efficient responses to future stress; this possibility is consistent with evidence on neural plasticity in emotional regulation systems ([36]; [38]).

In summary, EI can be conceptualized as a central psychological resource linking stress, resilience, and performance across multiple levels of analysis, including neurobiological, psychological, and organizational. This reinforces its relevance not only as a theoretical construct, but also as a critical variable for the sustainability of contemporary healthcare systems ([12]; [27]; [49]).

Although the accumulated evidence supports a robust association between EI, resilience, and adaptive functioning in healthcare contexts, this relationship is neither uniform nor universal. Its expression depends on moderating variables that shape how EI is developed, expressed, and translated into occupational outcomes.

One of the most consistent moderators is cultural context. EI is not culturally neutral, as it is influenced by social norms governing emotional expression, interpersonal communication, and professional behaviour ([28]; [33]). In collectivist cultures, emotional modulation may be valued as a sign of self-control and discipline, whereas in individualistic contexts, emotional expressiveness is often linked to authenticity and relational competence.

Gender is another relevant moderating factor. The literature on emotional labor shows that social expectations shape how men and women regulate and express emotions in professional settings, and healthcare professions, which are highly feminized in several regions, often involve a greater structural emotional load ([15]; [18]). These differences have been linked to variation in career trajectories, access to leadership roles, and levels of emotional exhaustion.

Professional experience and seniority also shape the relationship between EI and outcomes. More experienced professionals tend to use more efficient emotion regulation strategies, which may reflect experiential learning and neurocognitive adaptation over time. This pattern is consistent with the literature on plasticity and functional adaptation ([23]; [19]), as well as with models of emotion regulation based on learning and automatization throughout professional development ([38]).

At the organizational level, structural conditions play a decisive role. Factors such as workload, leadership, institutional resources, and organizational culture can amplify or weaken the protective effects of EI. In high-pressure care systems, even high EI may not be enough to prevent burnout, which reinforces the need for multisystemic approaches ([8]; [9], [10]; [27]; [44]).

From a methodological perspective, it is important to acknowledge substantial limitations in the existing literature. Many studies rely on cross-sectional designs, which restrict causal inference, and on self-report EI measures, which may introduce social desirability bias and inflate associations. Moreover, conceptual heterogeneity across trait, ability, and mixed EI models makes comparisons between studies difficult and contributes to variability in empirical findings. The distinction between trait and ability EI, alongside this broader conceptual fragmentation, is well documented in the literature ([30]; [48]) and underscores the need for longitudinal, multimethod research.

A further limitation concerns the profession-specific EI profiles proposed in this review (Section 4.1): these were inferred from separate, profession-specific literatures rather than from studies directly comparing physicians, nurses, support staff, and administrative personnel using standardized EI measures within the same design. Future research should prioritize multi-group comparative studies—ideally longitudinal and using common EI instruments—to empirically test whether these differentiated profiles hold.

Finally, the geographical representativeness of the evidence remains uneven, with a predominance of studies in Western contexts, which limits the global generalizability of current models ([28]; [33]).

Taken together, these limitations do not invalidate the main findings of the literature, but they do highlight the need for longitudinal, cross-cultural, and multimethod research. Within this framework, EI cannot be understood as an isolated trait or static competence, but rather as a dynamic adaptive system whose effectiveness depends on the interaction between neurocognitive mechanisms, emotional demands, and contextual conditions. Only through integrated approaches that connect individual and organizational levels will it be possible to understand more precisely how EI operates as a complex system. This perspective provides the basis for the theoretical and applied implications discussed in the following chapter.

Based on the evidence discussed above, the “Invisible Neurocognitive Shield” model can be formalized as a functional architecture that conceptualizes EI as an adaptive regulatory system. This model is organized around a dynamic chain of processes, EI, emotional regulation, resilience, and performance—which should be understood not as a linear sequence, but as a recursive system of continuous adaptation.

EI represents the entry point to this regulatory system, integrating the perception, understanding, and management of emotional information. In the [30]. model, these competencies are conceptualized as cognitive abilities for processing emotional information, hierarchically structured across emotional perception, facilitation, understanding, and management. By contrast, applied approaches such as that of [14] emphasize how these abilities translate into observable behavioral competencies in organizational contexts, particularly in professional performance and relational effectiveness.

Emotional regulation is the central mechanism through which EI competences are translated into adaptive action. In [16] process model, strategies such as cognitive reappraisal and attentional control modulate the intensity and duration of emotional responses, shaping real-time reactions to stressful stimuli. Within the present framework, amygdala-prefrontal interactions are incorporated as a proposed neurocognitive pathway relevant to emotional regulation, rather than as an established neural marker of EI ([38]; [39]).

Resilience emerges as the functional consequence of effective regulation, reflecting the capacity to maintain psychological stability and recover after stress exposure. This does not mean the absence of emotional response, but rather its efficient management over time, preserving adaptive functioning even in adverse contexts.

Performance is the operational dimension of the model, reflected in indicators such as quality of care, decision-making under pressure, and relational effectiveness in clinical settings. Empirical evidence suggests that professionals with stronger emotion-regulation capacity show better occupational adaptation and a lower impact of chronic stress ([44]; [51]), reinforcing EI as a functional factor in sustaining clinical effectiveness in highly demanding environments.

This model incorporates feedback mechanisms in which repeated practice in emotional regulation may contribute to adaptive changes in neurocognitive systems involved in executive control, potentially supporting more efficient responses to subsequent stress. This interpretation is consistent with evidence on neural plasticity in learning and adaptation ([3]), but does not imply that such neuroplastic changes have been directly demonstrated as a consequence of EI in healthcare professionals. Accordingly, the model treats neuroplasticity as a plausible process through which emotional-regulation capacities may develop over time, rather than as an established neurobiological mechanism of EI.

Thus, the “Invisible Neurocognitive Shield” is not merely a set of competences, but an integrated system linking biological, psychological, and organizational levels, providing a solid conceptual basis for applied interventions in health contexts.

The operationalization of EI in healthcare systems requires adaptation to the cultural and organizational specificities of each context. Although the neurocognitive mechanisms underlying emotional regulation share a broadly common functional basis, their expression is shaped by social norms, institutional structures, and cultural values ([28]; [33]).

In this sense, an application matrix can be conceptualized that aligns EI strategies with regional characteristics:

United States and Western contexts

Characterized by high professional autonomy and a strong emphasis on individual performance, these contexts benefit from interventions centred on emotional self-regulation, emotional leadership, and burnout prevention. The evidence also suggests that institutional programs have been increasingly integrating emotional competencies as a core component of professional well-being strategies ([44]).

Europe

In European systems, there is greater integration between health policies and occupational well-being. EI strategies are often incorporated into broader organizational approaches, including work-life balance and institutional culture ([8]).

Asia

In Asian contexts, characterized by stronger institutional hierarchy and more restrictive norms of emotional expression, EI may play a particularly adaptive role by helping professionals adjust emotional display to social expectations without compromising effectiveness. This pattern is consistent with the literature on cultural norms and “display rules”, which highlights the role of culture in shaping emotional experience and expression ([28]; [33]).

Latin America and the Global South

In these contexts, the high emotional load linked to structural limitations in healthcare systems coexists with greater vulnerability to burnout, as well as with the protective role of emotion-regulation strategies and resilience. The available evidence suggests that EI is especially important for adaptation in settings with high care pressure and limited resources ([17]; [21]; [47]).

Globally, the matrix suggests that EI is universal in its neurocognitive basis yet culturally situated in its expression and application, requiring adaptive and context-sensitive approaches.

In high-pressure clinical contexts, brief emotional-regulation strategies may be useful when they can be integrated into routine workflow with minimal disruption. The following micro-interventions are presented as illustrative, theory-informed practices rather than as standardized 60-second protocols with demonstrated effects on healthcare workforce or clinical outcomes. Their proposed mechanisms draw on broader evidence on emotion regulation, including regulated breathing, affect labelling, cognitive reappraisal, attentional pauses, and grounding.

These techniques are grounded in neurocognitive evidence showing that the prefrontal cortex can modulate amygdala activity, reducing emotional reactivity and supporting greater cognitive control and behavioural flexibility ([38]). Short interventions, sometimes implemented in brief periods of around 60 seconds, may engage these regulatory processes to support rapid emotional regulation in high-demand settings.

This timeframe does not imply that a 60-second duration has been empirically validated for each intervention or healthcare context. Future intervention studies should assess the feasibility, optimal duration, implementation conditions, and effects of these strategies on stress, burnout, professional well-being, decision-making, and quality of care among healthcare professionals (Table 4).

Taken together, these interventions constitute a low-latency set of strategies designed to modulate emotional responses in real time through different neurocognitive and behavioral pathways. However, their effectiveness and sustainability are

substantially greater when they are embedded within broader, system-level strategies for implementing EI.

The implementation of EI in healthcare systems requires a multisystemic approach that goes beyond individual intervention, integrating organizational, relational, and structural dimensions.

At the individual level, EI training programs have been shown to improve emotion regulation and reduce stress. The literature also suggests positive associations between structured interventions, clinical performance, and quality of care ([22]; [29]; [41]).

At the team level, integrating EI into leadership and communication practices strengthens cohesion and operational effectiveness. Conceptual and empirical studies suggest that leaders with high emotional competence tend to foster more stable, collaborative, and psychologically safe work environments ([14]).

At the organizational level, it is essential to align EI strategies with institutional policies and structural working conditions. Evidence suggests that interventions focused solely on the individual have limited impact unless accompanied by consistent organizational changes, particularly in leadership, institutional culture, and the conditions of clinical practice ([44]; [51]).

From an economic and operational point of view, the implementation of EI-based programs offers important advantages, including high scalability, relatively low cost, and cross-cutting effects on multiple indicators of performance and professional well-being, consistent with recent systemic approaches to quality of care in health ([11]; [45]).

In addition, integrating micro-interventions into everyday clinical practice supports a continuous and sustainable approach to emotional regulation, reducing reliance on more reactive and complex structured interventions.

In this context, EI can be conceptualized as a strategic, structuring resource for healthcare systems, with simultaneous effects on professionals’ well-being, the quality of care delivered, and organizational sustainability ([14]; [45]).
