Introduction
Burnout is now recognised as a major occupational hazard in nursing and a central threat to safe, high-quality health care. It is commonly described as a combination of emotional exhaustion, depersonalisation and reduced professional accomplishment that arises when work stress is intense and long-lasting (Maslach & Jackson, 1981; Maslach, Schaufeli & Leiter, 2001). The World Health Organization classifies burnout as an “occupational phenomenon” linked to chronic, unmanaged workplace stress, emphasising that it is specific to the work context rather than a mental illness in itself (World Health Organization, 2019).
In nursing, burnout is not only a problem for individual staff. A large body of evidence shows that it is closely linked to poorer patient outcomes, lower quality of care and reduced performance at organisational level (Aiken et al., 2002; Hall et al., 2016; Jun et al., 2021; Li et al., 2024). This article summarises the impact of burnout on three levels: nurses themselves, patients and safety, and healthcare organisations. It also highlights health coaching as a promising, but not sufficient, approach to support staff within wider system change.
Conceptual background: burnout and mental health
Maslach and colleagues describe burnout as a work-related syndrome with three main components: feeling emotionally drained, developing a detached or cynical attitude to patients, and experiencing a loss of effectiveness or achievement at work (Maslach & Jackson, 1981; Maslach, Schaufeli & Leiter, 2001). Nursing research confirms that this model fits the experience of many nurses exposed to high workload, low control and emotionally demanding care (Dall’Ora et al., 2020).
However, burnout has also been criticised for its overlap with conditions such as depression and anxiety. Symptoms like exhaustion, reduced motivation and difficulties concentrating are common to both burnout and depressive disorders, raising questions about whether burnout is truly distinct as a diagnosis (Bianchi & Schonfeld, 2023). Reviews of nursing burnout emphasise that there is no single agreed set of diagnostic criteria or cut-off scores and that measurement tools vary widely (Dall’Ora et al., 2020).
This ambiguity matters for impact. If depressive or anxiety disorders are mislabelled as “burnout”, nurses may not receive appropriate mental health assessment or treatment (Bianchi & Schonfeld, 2023). At the same time, evidence consistently shows that work environments characterised by high demands and low resources are strongly linked with the burnout profile, suggesting that burnout remains a useful concept for understanding how organisational pressures harm staff and care quality (Maslach & Leiter, 2016; Dall’Ora et al., 2020).
Impact of burnout on nurses’ health and functioning
Psychological health and wellbeing
Burnout has serious consequences for nurses’ mental health. Studies using standard burnout scales show that nurses with high emotional exhaustion and depersonalisation report much higher levels of stress, anxiety, depression, sleep problems and physical complaints than colleagues with low burnout scores (Hall et al., 2016; Dall’Ora et al., 2020). Systematic reviews conclude that burnout is associated with chronic fatigue, somatic symptoms and impaired general wellbeing among healthcare staff (Hall et al., 2016).
Early-career nurses appear particularly vulnerable. Longitudinal research shows that burnout can increase sharply during the first years of practice, especially when new graduates face heavy workloads, poor support and role conflict (Rudman & Gustavsson, 2011; Laschinger, Wong & Grau, 2013/2016). This early burnout is associated with reduced job satisfaction and greater intention to leave nursing, meaning that the impact is felt both by individuals and by the wider workforce (Laschinger, Wong & Grau, 2013/2016; Gendler et al., 2025).
Cognitive performance and clinical judgement
Burnout also affects how nurses think and function in their day-to-day work. A systematic review of burnout and cognition found that high burnout is linked with poorer attention, working memory and executive functioning, with moderate effect sizes, suggesting a real reduction in cognitive capacity (Deligkaris et al., 2014). Neurocognitive studies show that chronic work-related stress alters brain networks involved in emotion regulation and attention, which may further reduce concentration and decision-making under pressure (Golkar et al., 2014).
Clinicians who report high emotional exhaustion are more likely to report mistakes in their own practice, indicating that cognitive overload and reduced vigilance translate into safety risks (Tawfik et al., 2018). In nursing, similar patterns are seen: burnout is associated with self-reported difficulties completing tasks, reduced vigilance and missed or delayed care (Aiken et al., 2002; Stimpfel, Sloane & Aiken, 2012; Dall’Ora et al., 2020).
Motivation, professional identity and turnover
Burnout gradually erodes nurses’ motivation, sense of professional identity and commitment to their role. High emotional exhaustion is one of the strongest predictors of reduced professional efficacy and intention to leave (Maslach, Schaufeli & Leiter, 2001; Leiter & Maslach, 2009). Nurses with high burnout scores are significantly more likely to describe their job satisfaction as low and to state that they plan to leave their post or the profession (Aiken et al., 2002; Poghosyan et al., 2010; Dall’Ora et al., 2020).
Professional identity appears to play an important role in this process. Nurses who feel a strong connection to the profession report lower burnout and higher job satisfaction, while those under chronic stress with weaker professional identity show higher turnover intentions (Johnson et al., 2012; Gendler et al., 2025). Studies of nurse managers similarly show that burnout mediates the relationship between perceived stress and job satisfaction, and that psychological capital (hope, optimism, resilience and self-efficacy) only partly buffers this effect (Hu et al., 2025).
Burnout-driven turnover then feeds back into the system. When experienced nurses leave, remaining staff face higher workloads and more responsibility, which increases their own risk of burnout and further attrition (Leiter & Maslach, 2009; Aiken et al., 2014; Gendler et al., 2025).
Impact of burnout on patients and quality of care
A strong and consistent evidence base links nurse burnout to poorer patient outcomes. Large observational studies in acute hospitals show that higher levels of nurse burnout and heavier workloads are associated with higher mortality, more complications and lower patient satisfaction (Aiken et al., 2002; Aiken et al., 2011; Vahey et al., 2004). Systematic reviews and meta-analyses confirm that nurse burnout is significantly associated with adverse events, including medication errors, infections, falls and other safety incidents (Hall et al., 2016; de Lima Garcia et al., 2019; Jun et al., 2021; Li et al., 2024).
Staffing levels sit at the centre of this relationship. In a landmark study of over 10,000 nurses, each additional patient added to a nurse’s average workload increased the odds of high burnout and job dissatisfaction, and was associated with a 7% increase in both mortality and failure-to-rescue following complications (Aiken et al., 2002). Subsequent studies in the United States and across Europe show similar patterns: when nurses care for more than six patients each, rates of burnout, missed care and mortality rise, whereas hospitals with safer nurse-to-patient ratios and higher proportions of registered nurses have better outcomes (Aiken et al., 2011; Aiken et al., 2014; Aiken et al., 2018; Griffiths et al., 2016).
Specialty-specific research reinforces these findings. For example, work from Malawi and other low-resource settings shows that when nurses manage extremely high caseloads with minimal support, burnout is common and patient safety is compromised through increased errors, reduced adherence to infection control and delayed care (Chinguwo, 2025). These findings align with the broader international evidence linking burnout, staffing and safety (Hall et al., 2016; Li et al., 2024).
Mechanisms connecting burnout to patient outcomes are both cognitive and relational. Emotional exhaustion reduces attention and decision-making accuracy, increasing the likelihood of clinical mistakes (Deligkaris et al., 2014; Tawfik et al., 2018). Depersonalisation leads to less empathy and poorer communication, which can weaken therapeutic relationships and shared decision-making (Maslach & Leiter, 2016; Poghosyan et al., 2010). Nurses with high burnout are more likely to rate the quality of care on their last shift as fair or poor and to report that essential nursing tasks were left undone due to lack of time (Vahey et al., 2004; Stimpfel, Sloane & Aiken, 2012; Griffiths et al., 2016).
Impact of burnout on organisations and health systems
Burnout has important consequences for organisations through its effects on performance, workforce stability and safety culture. At ward level, high burnout is associated with increased sickness absence, presenteeism, reduced productivity and poorer teamwork (Leiter & Maslach, 2009; Hall et al., 2016). Nurses experiencing burnout are less likely to recommend their workplace, participate fully in improvement activities or engage with organisational goals (Poghosyan et al., 2010; Vahey et al., 2004).
At system level, surveys across the NHS show that many staff report feeling unwell due to work-related stress and believe that there are not enough staff to do their job properly (The King’s Fund, 2024). Analyses from the Royal College of Nursing link millions of lost working days each year to stress, anxiety and depression among nurses, much of which is associated with unmanageable workload and chronic understaffing (Royal College of Nursing, 2024b; Royal College of Nursing, 2025a). Burnout therefore carries substantial financial costs through sickness absence, early retirement and the need to recruit and train replacement staff (Royal College of Nursing, 2025b).
Quality and safety bodies increasingly view staff wellbeing as a precondition for safe care. The National Quality Forum describes workforce safety and wellbeing as essential to patient safety, while health-system strategies highlight staff wellbeing as a core component of quality improvement (National Quality Forum, 2017; NHS England, 2023). Embedding measures of burnout and engagement into organisational dashboards is one way in which systems are beginning to acknowledge the impact of staff experience on care outcomes (Hall et al., 2016; Li et al., 2024).
Health coaching as a supportive response to burnout
Given the scale of the problem, there is growing interest in interventions that can reduce burnout and support recovery. Evidence suggests that professional coaching is one of several individual-level approaches that can reduce symptoms of burnout, particularly emotional exhaustion, when delivered alongside broader organisational changes (West et al., 2016; Collett & Cohen, 2024; Cohen et al., 2023).
Randomised trials in physicians show that a small number of structured coaching sessions can lead to meaningful reductions in emotional exhaustion and overall burnout, as well as improvements in quality of life (Dyrbye et al., 2019; Kiser et al., 2024; Khalili, West & Dyrbye, 2025). Umbrella reviews and meta-analyses conclude that coaching is probably effective in reducing some aspects of burnout, though effect sizes are modest and the evidence base is still developing (Collett & Cohen, 2024; Cohen et al., 2023).
Evidence specific to nurses is emerging. Quality-improvement projects and mixed-methods evaluations of coaching programmes in emergency and critical care nursing report improvements in resilience, wellbeing and burnout scores, along with reduced turnover intentions (Franklin, 2022; Hines-Stellisch, Smith & Johnson, 2024; Vogt et al., 2024). Trials of character-strengths-based coaching and resilience coaching suggest that coaching can increase personal resources, work engagement and desire to remain in the profession (Bondre et al., 2024; Franklin, 2022). Health coaching that supports self-care behaviours, such as physical activity, may also reduce burnout risk indirectly by improving overall mental health (Lomas et al., 2019; Nerek et al., 2024).
However, the literature is clear that coaching and other individual-level interventions cannot fully counteract the impact of unsafe staffing, excessive workload and unsupportive leadership (West et al., 2016; Dall’Ora et al., 2020; Li et al., 2024). Coaching appears to work best as part of a multi-level strategy that includes safe staffing, supportive management and psychologically informed workplace cultures (West et al., 2016; Hu et al., 2025; Royal College of Nursing, 2025a).
Conclusion
Burnout in nursing is a complex, work-related syndrome that arises when prolonged job demands exceed the resources available to staff. Its impact is profound. For nurses, it is linked to poorer mental health, impaired cognition, reduced motivation and higher turnover. For patients, it is associated with lower quality of care, more errors, adverse events and increased mortality. For organisations and health systems, burnout contributes to workforce instability, reduced productivity, weaker safety culture and higher costs.
Evidence shows that addressing burnout requires action at multiple levels. Structural measures such as safe nurse-to-patient ratios, adequate registered-nurse skill mix and supportive leadership are central to preventing burnout and protecting patient safety (Aiken et al., 2014; Aiken et al., 2018; Dall’Ora et al., 2020; Zaranko et al., 2023). At the same time, interventions that strengthen psychological resources—such as health coaching, resilience training and mindfulness—can help nurses cope with ongoing stress when embedded within a supportive organisational context (West et al., 2016; Franklin, 2022; Collett & Cohen, 2024).
Overall, the impact of burnout on healthcare professionals, patients and organisations underscores that staff wellbeing is not a “nice to have” but a core element of safe, effective and sustainable health care.
