COVID-19 health workers suffer combat-type moral trauma

A Duke University study shows that, amid COVID-19, US healthcare workers (HCWs) had similar rates of potential moral injury (PMI)—a type of trauma-induced wound to the psyche—as military combat veterans.

The study, published yesterday in the Journal of General Internal Medicinesurveyed 2,099 HCWs in 2020 and 2021 and 618 military veterans deployed to a combat zone after the Sep 11, 2001, US terrorist attacks about PMIs they may have experienced.

PMI is a distressing reaction to exposure to traumatic events that may have psychological, behavioral, social, and spiritual effects.

Depression, lower quality of life

Of the 618 veterans, 46.1% reported experiencing PMI induced by others’ immoral actions, compared with 50.7% of HCWs, while 24.1% and 18.2%, respectively, reported being disturbed by violations of their own moral code.

Combat veterans who reported PMIs induced by others had higher rates of depression; average Beck Depression Inventory-2 score among veterans reporting other-induced PMI was 22.34, versus 13.61 among those not reporting this type of PMI. They also had lower quality of life (average Short Form Survey score, 46.70 vs 59.98, respectively).

Likewise, compared with veterans who did not report self-induced PMI, those who did had significantly greater levels of depression (average Beck score, 24.55 vs 15.44) and lower quality of life (average Short Forum score, 45.71 vs 55.73).

Other-induced PMI among HCWs was significantly tied to younger age and COVID-19 exposure, while self-induced PMI was linked with younger age, non-White race, working in a high-risk setting, and COVID-19 exposure. Compared with HCWs who didn’t report other-induced PMI, those who did had greater levels of depression on the Beck Inventory (average score, 54.43 vs 50.67) and poorer quality of life (average Short Form score, 3.98 vs 4.16).

Similarly, compared with HCWs who didn’t report self-induced PMI, those who did had significantly higher levels of depression (average score, 55.67 vs 51.75) and poorer quality of life (3.88 vs 4.12). Levels of burnout were significantly greater among HCWs who reported other-induced PMI (average score on single question used in the HERO study, 2.65 vs 2.28) and self-induced PMI (2.77 vs 2.39).

When HCW actions conflict with beliefs

“Moral injuries can happen when health care workers’ values ​​and beliefs conflict with their actions or the ways they witness others acting,” lead author Jason Nieuwsma, PhD, a Department of Veterans Affairs (VA) and Duke researcher, said in a Duke Health press release.

“While ‘burnout’ is often used to describe the effects of ongoing stress in the workplace, moral injury is used to describe the damage done to the conscience or identity of people who might witness, cause, or fail to prevent acts that go against their own moral standards,” he said.

“For example, with health care workers, this might entail them making choices or being part of situations that stray from their genuine commitment to healing.”

Role of workplace culture, leadership

The HCWs were participants in Duke’s Healthcare Worker Exposure Response and Outcomes (HERO) registry, and the veterans were part of the Post-Deployment Mental Health Moral Injury study, conducted by the VA Boston Healthcare System. Average age was 47.3 years for veterans and 44.5 years for HCWs.

During their service, 84.6% of veterans were enlisted, and the average number of deployments was 1.95. Among HCWs, 42.0% were diagnosing patients, 22.2% worked in high-risk settings, 45.3% said they were exposed to COVID-19, and 6.1% were infected.

HCWs said that PMI stemmed from witnessing patient deaths, rationed care, policies that kept families from dying patients, and the public’s disregard for slowing COVID-19 transmission. It was also triggered by staff shortages and a lack of personal protective equipment.

“It is sobering to see how many health care workers are troubled at a moral level because of their work experiences during the pandemic,” Nieuwsma said. “This may help us to understand some of the current challenges facing health care systems across the country.”

Senior author Keith Meador, MD, ThM, MPH, of Vanderbilt University, said in the release that the study findings may inform the VA’s approach to PMI. “Our study is suggestive with respect to the importance of workplace culture and leadership for moral injury in health care,” he said. “I think the role of the community, whether that be at work or elsewhere, is truly central.”

Longitudinal research into HCW PMI and evaluation of potential interventions are needed, the study authors said.

“While we can learn things from comparing veterans and health care workers, the two populations are also different in many important ways, and it remains to be seen how pervasive moral injury proves to be in health care contexts over time,” Nieuwsma said.
