Main findings
This study investigated the relationship between resilience, job satisfaction, burnout and team development among teamlet members. Family physicians reported the highest burnout scores across all three domains of the MBI. There were no significant differences in TDM and resilience scores among Family physicians, Care managers and Care Coordinators. Age more than 55 years were negatively associated with TDM scores while presence of social interaction outside of work, lower depersonalisation scores and higher job satisfaction scores were positively associated with TDM scores after controlling for other independent variables.
Burnout, Depersonalisation and Job satisfaction
More than half of physicians and one-third of nurses in the United States experience symptoms of burnout.20 Those working in front line disciplines like family medicine are at a higher risk for burnout.21 The prevalence of burnout among teamlet family physicians in our study was 31.8%, lower than the reported prevalence of 80.7% among residents from Singhealth residency in a local study in 2018. A more recent study by the Singapore Health Services (SHS) cluster in 2019-2020 showed that 62.0% of the survey respondents in the Medical group experienced a high burnout score.22 However, the latter studies used a different definition of burnout as having a high subscore on any MBI subdomain whereas our study defined burnout according to the updated Maslach-recommended criteria of high EE and high DP or high EE and low PA.23 The marked heterogeneity in burnout definitions in the literature contributing to variability in published prevalence burnout estimates had been reported in a systematic review, highlighting the importance of developing a consensus definition of burnout.24 The Medscape National Physician Burnout & Suicide Report 2020 found that 46% of family physicians in the United States had burnout.25
Studies have shown that burnout among physicians is caused by a myriad of factors. These range from heavy administrative burden, pressure to learn new technology, long working hours, time pressure during consults, to a lack of alignment regarding values, mission, and purpose.21,26 In November 2021, Singapore’s Ministry of Health released statistics showing that about 1500 healthcare workers resigned in the first half of 2021, compared with 2000 annually before the Covid-19 pandemic.27 The two-year average attrition rate was 9.8% in 2021. A qualitative analysis of e-diary data involving more than 600 healthcare workers in Singapore in mid-July to mid-August 2020 showed that the most commonly shared theme was the cumulative burnout from being overworked and emotional exhaustion.28 This study was conducted during a time of heavy infection control restrictions, stringent quarantine and contact tracing measures during the pandemic. Not being able to take adequate leave and allocate time for self-care contributed to experiences of burnout in certain local institutions. The lack of appreciation at work also affected the morale of healthcare workers, especially among female nurses. Conversely, morale boosters described in the study included a devotion to service, being motivated and inspired by strong leadership and supportive colleagues. Leadership that went the extra mile for both staff and patients were lauded. Staff also derived assurance and job satisfaction from working with highly competent peers that they respected.
Burnout rates in care managers were lower (6.5%) when compared to a study involving nurse practitioners and physician assistants in the United States (22.6%).29 The study by SHS in 2019-2020 revealed that 71.3% of nurses had high burnout scores in at least 1 MBI subdomain, 36.0% had high burnout scores in at least 2 MBI subdomains and 16.8% had high burnout scores in all 3 MBI subdomains.22 While burnout in care coordinators in the primary care setting is less studied, our study showed that 14.8% of teamlet care coordinators had burnout, lower than that reported (18.0%) among non-clinical staff working in primary care settings in the United States.29 The proportion of nurses in Singapore public hospitals who resigned in 2021 was 7.4%, reaching a five-year high. The increase was higher for foreign nurses in the public sector, with 14.8% resigning.30 The pandemic has indeed taken a toll on nurses, creating a nursing crunch that may stay in the coming years.31 A possible reason why burnout rates in our study was lower could be due to the different practice environment and working schedules. In our polyclinic setting, nurses have a fixed work schedule with no on call or overnight shifts. Working in integrated teamlets delivering patient care as a team helps to foster camaraderie and promote better relationships and emotional support between members, which is crucial during times of crisis like during the pandemic.
Our study also showed that lower depersonalisation scores and higher job satisfaction scores were associated with TDM scores after controlling for other independent variables. Depersonalisation can be described as the development of a callous and cynical attitude towards the recipients of one’s services.32 The three burnout dimensions of EE, DP and PA usually do not develop simultaneously. The sequential order of these concerns the development of burnout and may be relevant for early recognition and preventive interventions. Golembiewski et al argues that depersonalisation is experienced first as some level of detachment is needed when providing medical services.33 Eventually detachment leads to depersonalisation and triggers emotional strain. Other researchers like Leiter and Maslach maintain that emotional exhaustion develops first as a response to chronic job stress, which then leads to depersonalisation to cope with the stressors.34 These subsequently lead to a feeling of reduced personal accomplishment.
Social connectedness
Our study showed that the presence of social interaction outside work was positively associated with better team development. Social connectedness, especially in the form of teamwork, addresses the psychological needs of friendship, a sense of belonging and adds meaningfulness to one’s work.35 Positive and rewarding human connections are known to be beneficial to mental well-being and can reduce burnout.35 When team members discover meaning in their work through interaction with other members involving trust, respect and confidence, believing the best in one another and tolerating mistakes, they can inspire each other and enhance teamwork. 36 In contrast, a study among healthcare professionals showed that loneliness was positively associated with somatisation, emotional detachment and dehumanisation.37 Social interaction is a social exchange between two or more individuals which form the basis for social structure, group dynamics and conformity. These interactions can be categorised into accidental, repeated, regular and regulated. A previous study showed that small increases in social cohesion had large influences on better productivity even when interactions were not work related.38 This highlights that it is the strength of the relationship that matters. Our study results are therefore not surprising.
It is likely that social interaction outside work starts with positive social interaction at work. Structural strategies to provide opportunities for socialisation may help to foster meaningful, high-quality social connections among teamlet members. In the newer NHGP polyclinics, there are designated “huddle rooms” with computers, projectors, notice boards and white boards to facilitate inter-professional discussions, planning of upcoming patient visits, team projects and initiatives. These huddles could be as short as five minutes before the start of a clinic session to get a glimpse of what is expected for the day. Longer sessions lasting up to an hour to discuss complex patients during working hours may also be planned. This gives the teamlet members a sense of unity, a channel for open discussion and feedback, and ensures that every member is on the same page. Teamlet leaders who encourage informal interactions such as out of hours social gatherings or team-building activities can further help to foster the development of more positive social relationships among members.
