Health care professionals working in critical care settings have been overburdened because of the plethora of COVID-19 cases, which has led to symptoms of burnout in both physicians and nurses, findings from a new study show.
“Overburdening ICU professionals during an extended period of time leads to burnout,” said lead study author Niek Kok, MSc, of IQ healthcare, Radboud University Medical Center, Radboud Institute for Health Sciences, Nijmegen, the Netherlands. “All ICU professionals are at the risk of this, and in our study, the incidence of physicians experiencing burnout was significantly higher than that of nurses in June 2020.”
This burnout can be explained by conditions caused by the pandemic, he noted, such as the scarcity of staff and resources and having to work with colleagues who were not qualified to work in critical care but who were there out of necessity.
Mr. Kok presented the findings of the study at the Critical Care Congress sponsored by the Society of Critical Care Medicine.
Burnout highest among critical care physicians
The ICU can be a stressful environment for both patients and health care personnel, and burnout is not uncommon among ICU clinicians. However, COVID-19 has amplified the degree of burnout being experienced by clinicians working in this setting. Critical care physicians now top the list of physicians experiencing burnout, at 51%, up from 44% last year, according to the Medscape report ‘Death by 1000 Thousand Cuts’: Physician Burnout and Suicide Report 2021.
The Medscape Nurse Career Satisfaction Report 2020, while not restricted to those working in critical care, also reported higher rates of burnout, compared with the prepandemic period. The percentage of nurses reporting being “very burned out” prior to the pandemic was 4%. Six months into the pandemic, that percentage soared to 18%.
In this study, Mr. Kok and colleagues examined the prevalence and incidence of burnout symptoms and moral distress in health care professionals working in the ICU, both before and during the COVID-19 pandemic.
“When the COVID-19 pandemic surfaced in the Netherlands, the health care professionals in our hospitals were motivated to do everything they could to provide the best care possible,” said Mr. Kok. “Many of the ICU professionals immediately realized that they would have to work longer hours.”
However, the health care professionals that he spoke with did have mixed feelings. Some were afraid of being infected with the virus, while others said that “it was very interesting times for them and that gave them extra motivation to do the work.
“Some physicians [and] the WHO warned that COVID-19 is not going to weathered by a heroic sprint – it is an arduous marathon that is going to go hand in hand with burnout symptoms,” Mr. Kok added. “It will eat away at our qualified ICU staff.”
Before and after data on burnout
It was widely believed that the COVID-19 pandemic would increase burnout symptoms, as had been demonstrated in studies of previous pandemics. However, Mr. Kok emphasized that there are no before and after measurements that transcend cross-sectional designs.
“The claim [has been] that it increases burnout – but there are no assessments of how it progresses in ICU professionals through time,” he said. “So what we really need is a comparison [of] before and after the pandemic.”
It is quite difficult to obtain this type of information because disruptive events like the COVID-19 pandemic cannot be predicted, he said. Thus, it is challenging to get a baseline measurement. But Mr. Kok pointed out that the study has both “before and after” measurements.
“By coincidence really, we had baseline data to measure the impact of the COVID-19 pandemic and had information that was collected before the pandemic,” he said.
In January 2020, a study began looking at the effects of ethics meetings on moral distress in ICU professionals. Data had been collected on moral distress and burnout on ICU professionals in December 2019. The first COVID-19 cases appeared in the Netherlands in February 2020.
A follow-up study was then conducted in May and June 2020, several months into the pandemic.
The longitudinal open cohort study included all ICU personnel who were working in five units within a single university medical center, plus another adult ICU that was based in a separate teaching hospital.
A total of 352 health care professionals responded to a baseline survey in October through December 2019, and then 233 responded to a follow-up survey sent in May and June 2020. The authors measured burnout symptoms and moral distress with the Maslach Burnout Inventory and the Moral Distress Scale, respectively.
The overall prevalence of burnout symptoms was 23.0% prior to the pandemic, and that jumped to 36.1% at post-peak time. Higher rates of burnout were reported by nurses (38.0%) than physicians (28.6%).
However, the incidence rate of new burnout cases was higher among physicians, compared with nurses (26.7% vs 21.9%). Not surprisingly, a higher prevalence of burnout symptoms was observed in the post-peak period for all clinicians (odds ratio, 1.83; 95% confidence interval, 1.32-2.53), and was higher for nurses (odds ratio, 1.77; 95% confidence interval, 1.03-3.04), for those working overtime (OR, 2.11; 95% CI, 1.48-3.02), and for personnel who directly engaged in patient care (OR, 1.87; 95% CI, 1.35-2.60).
Physicians in general were much more likely to develop burnout symptoms related to the pandemic, compared with nurses (OR, 3.56; 95% CI, 1.06-12.21).
When looking at findings on moral distress, Kok pointed out that it often arises in situations when the health care professional knows the right thing to do but is prevented from doing so. “Morally distressful situations all rose from December to June,” said Mr. Kok. “Scarcity was the most distressing. The other was where colleagues were perceived to be less skilled, and this had to do with the recruitment of people from outside of the ICU to provide care.”
Moral distress from scarcity and unskilled colleagues were both significantly related to burnout, he noted.
In the final model, working in a COVID-19 unit, stress from scarcity of resources and people, stress from unskilled colleagues, and stress from unsafe conditions were all related to burnout. “The stress of physicians was significantly higher,” said Kok. “Even though nurses had higher baseline burnout, it became less pronounced in June 2020. This indicates that burnout was significantly higher in physicians.”
Thus, Mr. Kok and colleagues concluded that overburdening ICU professionals during an extended period of time leads to burnout, and all ICU workers are at risk.
