“ Hope is engagement with the act of mapping our destinies.” ¹

—Valerie Braithwaite

Why should psychiatrists care about climate change and try to mitigate its effects? First, we are tasked by society with managing the psychological and neuropsychiatric sequelae from disasters, which include climate change. The American Psychiatric Association’s position statement on climate change includes it as a legitimate focus for our specialty.² Second, as physicians, we are morally obligated to do no harm. Since the health care sector contributes significantly to climate change (8.5% of national carbon emissions stem from health care) and causes demonstrable health impacts,³ managing these impacts and decarbonizing the health care industry is morally imperative.⁴ And third, psychiatric clinicians have transferrable skills that can address fears of climate change, challenge climate change denialism,⁵ motivate people to adopt more pro-environmental behaviors, and help communities not only endure the emotional impact of climate change but become more psychologically resilient.⁶

Most psychiatrists, however, did not receive formal training on climate change and the related field of disaster preparedness. For example, Harvard Medical School did not include a course on climate change in their medical student curriculum until 2023.⁷ In this article, we provide a basic framework of climate change and its impact on mental health, with particular focus on patients with serious mental illness (SMI). We offer concrete steps clinicians can take to prevent or mitigate harm from climate change for their patients, prepare for disasters at the level of individual patient encounters, and strengthen their clinics and communities. We also encourage clinicians to take active leadership roles in their professional organizations to be part of climate solutions, building on the trust patients continue to have in their physicians.⁸ Even if clinicians do not view climate change concerns under their conceived clinical care mandate, having a working knowledge about it is important because patients, paraprofessional staff, or medical trainees are likely to bring it up.⁹

Climate change and mental health

Climate change is harmful to human health, including mental health.¹⁰ It can impact mental health directly via its impact on brain function and neuropsychiatric sequelae, and indirectly via climate-related disasters leading to acute or chronic stress, losses, and displacement with psychiatric and psychological sequelae (Table 1^11-29).

Direct impact

The effects of air pollution, heat, infections, and starvation are examples of how climate change directly impacts mental health. Air pollution and brain health are a concern for psychiatry, given the well-described effects of air deterioration on the developing brain.¹¹ In animal models, airborne pollutants lead to widespread neuroinflam­mation and cell loss via a multitude of mechanisms.¹² This is consistent with worse cognitive and behavioral functions across a wide range of cognitive domains seen in children exposed to pollution compared to those who grew up in environments with healthy air.¹³ Even low-level exposure to air pollution increases the risk for later onset of depression, suicide, and anxiety.¹⁴ Hippocampal atrophy observed in patients with first-episode psychosis may also be partially attributable to air pollution.¹⁵ An association between heat and suicide (and to a lesser extent, aggression) has also been reported.¹⁶

Worse physical health (eg, strokes) due to excessive heat can further compound mental health via elevated rates of depression. Data from the United States and Mexico show that for each degree Celsius increase in ambient temperature, suicide rates may increase by approximately 1%.¹⁷ A meta-analysis by Frangione et al¹⁸ similarly concluded that each degree Celsius increase results in an overall risk ratio of 1.016 (95% CI, 1.012 to 1.019) for deaths by suicide and suicide attempts. Additionally, global warming is shifting the endemic areas for many infectious agents, particularly vector-borne diseases,¹⁹ to regions in which they had hitherto been unknown, increasing the risk for future outbreaks and even pandemics.²⁰ These infectious illnesses often carry neuropsychiatric morbidity, with seizures, encephalopathy with incomplete recovery, and psychiatric syndromes occurring in many cases. Crop failure can lead to starvation during pregnancy and childhood, which has wide-ranging consequences for brain development and later physical and psychological health in adults.^21,22 Mothers affected by starvation also experience negative impacts on childbearing and childrearing.²³

Indirect impact

Climate change’s indirect impact on mental health can stem from the stress of living through a disaster such as an extreme weather event; from losses, including the death of friends and family members; and from becoming temporarily displaced.²⁴ Some climate change–driven disasters can be viewed as slow-moving, such as drought and the rising of sea levels, where displacement becomes permanent. Managing mass migration from internally or externally displaced people who must abandon their communities because of climate change will have significant repercussions for all societies.²⁵ The term “climate refugee” is not (yet) included in the United Nations’ official definition of refugees; it defines refugees as individuals who have fled their countries because of war, violence, or persecution.²⁶ These and other bureaucratic issues can come up when clinicians are trying to help migrants with immigration-related paperwork.

Continue to: As the inevitability of climate change...

As the inevitability of climate change sinks in, its long-term ramifications have introduced a new lexicon of psychological suffering related to the crisis.²⁷ Common terms for such distress include ecoanxiety (fear of what is happening and will happen with climate change), ecogrief (sadness about the destruction of species and natural habitats), solastalgia²⁸ (the nostalgia an individual feels for emotionally treasured landscapes that have changed), and terrafuria or ecorage (the reaction to betrayal and inaction by governments and leaders).²⁹ Climate-related emotions can lead to pessimism about the future and a nihilistic outlook on an individual’s ability to effect change and have agency over their life’s outcomes.

The categories of direct and indirect impacts are not mutually exclusive. A child may be starving due to weather-related crop failure as the family is forced to move to another country, then have to contend with prejudice and bullying as an immigrant, and later become anxiously preoccupied with climate change and its ability to cause further distress.

Effect on individuals with serious mental illness

Patients with SMI are particularly vulnerable to the impact of climate change. They are less resilient to climate change–related events, such as heat waves or temporary displacement from flooding, both at the personal level due to illness factors (eg, negative symptoms or cognitive impairment) and at the community level due to social factors (eg, weaker social support or poverty).

Recognizing the increased vulnerability to heat waves and preparing for them is particularly important for patients with SMI because they are at an increased risk for heat-related illnesses.³⁰ For example, patients may not appreciate the danger from heat and live in conditions that put them at risk (ie, not having air conditioning in their home or living alone). Their illness alone impairs heat regulation³¹; patients with depression and anxiety also dissipate heat less effectively.^32,33 Additionally, many psychiatric medications, particularly antipsychotics, impair key mechanisms of heat dissipation.^34,35 Antipsychotics render organisms more poikilothermic (susceptible to environmental temperature, like cold-blooded animals) and can be anticholinergic, which impedes sweating. A recent analysis of heat-related deaths during a period of extreme and prolonged heat in British Columbia in 2021 affirmed these concerns, reporting that patients with schizophrenia had the highest odds of death during this heat-related event.³⁶

COVID-19 has shown that flexible models of care are needed to prevent disengagement from medical and psychiatric care³⁷ and assure continued treatment with essential medications such as clozapine³⁸ and long-acting injectable antipsychotics³⁹ during periods of social change, as with climate change. While telehealth was critical during the COVID-19 pandemic⁴⁰ and is here to stay, it alone may be insufficient given the digital divide (patients with SMI may be less likely to have access to or be proficient in the use of digital technologies). The pandemic has shown the importance of public health efforts, including benefits from targeted outreach, with regards to vaccinations for this patient group.^41,42Table 2 summarizes things clinicians should consider when preparing patients with SMI for the effects of climate change.

Continue to: The psychiatrist's role

There are many ways a psychiatrist can professionally get involved in addressing climate change. Table 3^43-53 outlines the 3 Ps of climate action (taking actions to mitigate the effects of climate change): personal, patient (and clinic), and political (advocacy).

Personal

Even if clinicians believe climate change is important for their clinical work, they may still feel overwhelmed and unsure what to do in the context of competing responsibilities. A necessary first step is overcoming paralysis from the enormity of the problem, including the need to shift away from an expanding consumption model to environmental sustainability in a short period of time.

A good starting point is to get educated on the facts of climate change and how to discuss it in an office setting as well as in your personal life. A basic principle of climate change communication is that constructive hope (progress achieved despite everything) coupled with constructive doubt (the reality of the threat) can mobilize people towards action, whereas false hope or fatalistic doubt impedes action.⁴³ The importance of optimal public health messaging cannot be overstated; well-meaning campaigns to change behavior can fail if they emphasize the wrong message. For example, in a study examining COVID-19 messaging in >80 countries, Dorison et al⁴⁴ found that negatively framed messages mostly increased anxiety but had no benefit with regard to shifting people toward desired behaviors. The best public health messages are brief, repeated, and delivered by a trusted person.⁴⁵ Good messages are targeted to a concrete concern and where action would pay off now and not in some distant future.

In addition, clinicians can learn how to confront climate disavowal and difficult emotions in themselves and even plan to shift to carbon neutrality, such as purchasing carbon offsets or green sources of energy and transportation. They may not be familiar with principles of disaster preparedness or crisis communication.⁴⁶ Acquiring those professional skills may suggest next steps for action. Being familiar with the challenges and resources for immigrants, including individuals displaced due to climate change, may be necessary.⁴⁷ Finally, to reduce the risk of burnout, it is important to practice self-care, including strategies to reduce feelings of being overwhelmed.

Patient

In clinical encounters, clinicians can be proactive in helping patients understand their climate-related anxieties around an uncertain future, including identifying barriers to climate action.⁴⁸Emphasizing that climate action has health benefits for them and their communities now (eg, less polluted air leading to fewer health problems related to pollution) may engage patients unsure about their role in the fight against climate change. This simple message overcomes the human preference for immediate and concrete benefits over investment in long-term gains. Some patients may respond to the suggestion that adopting a plant-based diet is beneficial for their own health as well as for planetary health, given the substantial contribution of animal farming to global warming.⁴⁹

Continue to: Clinics must prepare for disasters...

Clinics must prepare for disasters in their communities to prevent disruption of psychiatric care by having an action plan, including the provision of medications. Such action plans should be prioritized for the most likely scenarios in an individual’s setting (eg, heat waves, wildfires, hurricanes, or flooding).

It is important to educate clinic staff and include them in planning for emergencies, because an all-hands approach and buy-in from all team members is critical. Clinicians should review how patients would continue to receive services, particularly medications, in the event of a disaster. In some cases, providing a 90-day medication supply will suffice, while in others (eg, patients receiving long-acting antipsychotics or clozapine) more preparation is necessary. Some events are predictable and can be organized annually, such as clinicians becoming vaccine ambassadors and organizing vaccine campaigns every fall⁵⁰; winter-related disaster preparation every fall; and heat wave education every spring (leaflets for patients, staff, and family members; review of safety of medications during heat waves). Plan for, monitor, and coordinate medical care and services for climate refugees and other populations that may otherwise delay medical care and impede illness prevention. Finally, support climate refugees, including connecting them to services or providing trauma-informed care.

Political

Some clinicians may feel compelled to become politically active to advocate for changes within the health care system. Two initiatives related to decarbonizing the health care sector are My Green Doctor⁵¹ and Health Care Without Harm,⁵² which offer help in shifting your office, clinic, or hospital towards carbon neutrality.

Climate change unevenly affects people and will continue to exacerbate inequalities in society, including individuals with mental illness.⁵³ To work toward climate justice on behalf of their patients, clinicians could join (or form) climate committees of special interest groups in their professional organizations or setting. Joining like-minded groups working on climate change at the local or national level prevents an omission of a psychiatric voice and counteracts burnout. It is important to stay focused on the root causes of the problem during activism: doing something to reduce fossil fuel use is ultimately most important.⁵⁴ The concrete goal of reaching the Paris 1.5-degree Celsius climate goal is a critical benchmark against which any other action can be measured.⁵⁴

Planning for the future

Over the course of history, societies have always faced difficult periods in which they needed to rebuild after natural disasters or self-inflicted catastrophes such as terrorist attacks or wars. Since the advent of the nuclear age, people have lived under the existential threat of nuclear war. The Anthropocene is a proposed geological term that reflects the enormous and possibly disastrous impact human activity has had on our planet.⁵⁵ While not yet formally adopted, this term has heuristic value, directing attention and reflection to our role and its now undisputed consequences. In the future, historians will debate if the scale of our current climate crisis has been different. It is, however, not controversial that humanity will be faced with the effects of climate change for the foreseeable future.¹⁰ Already, even “normal” weather events are fueled by energy in overcharged and altered weather systems due to global warming, leading to weather events ranging from droughts to floods and storms that are more severe, more frequent, and have longer-lasting effects on communities.⁵⁶

Continue to: As physicians, we are tasked...

As physicians, we are tasked by society to create and maintain a health care system that addresses the needs of our patients and the communities in which they live. Increasingly, we are forced to contend with an addition to the traditional 5 phases of acute disaster management (prevention, mitigation, preparedness, response, and recovery) to manage prolonged or even parallel disasters, where a series of disasters occurs before the community has recovered and healed. We must grapple with a sense of an “extended period of insecurity and instability” (permacrisis) and must better prepare for and prevent the polycrisis (many simultaneous crises) or the metacrisis of our “age of turmoil”⁵⁷ in which we must limit global warming, mitigate its damage, and increase community resilience to adapt.

Leading by personal example and providing hope may be what some patients need, as the reality of climate change contributes to the general uneasiness about the future and doomsday scenarios to which many fall victim. At the level of professional societies, many are calling for leadership, including from mental health organizations, to bolster the “social climate,” to help us strengthen our emotional resilience and social bonds to better withstand climate change together.⁵⁸ It is becoming harder to justify standing on the sidelines,⁵⁹ and it may be better for both our world and a clinician’s own sanity to be engaged in professional and private hopeful action¹ to address climate change. Without ecological or planetary health, there can be no mental health.

Bottom Line

Clinicians can prepare their patients for climate-related disruptions and manage the impact climate change has on their mental health. Addressing climate change at clinical and political levels is consistent with the leadership roles and professional ethics clinicians face in daily practice.

Climate change’s indirect impact on mental health can stem from the stress of living through a disaster such as an extreme weather event; from losses, including the death of friends and family members; and from becoming temporarily displaced.²⁴ Some climate change–driven disasters can be viewed as slow-moving, such as drought and the rising of sea levels, where displacement becomes permanent. Managing mass migration from internally or externally displaced people who must abandon their communities because of climate change will have significant repercussions for all societies.²⁵ The term “climate refugee” is not (yet) included in the United Nations’ official definition of refugees; it defines refugees as individuals who have fled their countries because of war, violence, or persecution.²⁶ These and other bureaucratic issues can come up when clinicians are trying to help migrants with immigration-related paperwork.

Continue to: As the inevitability of climate change...

As the inevitability of climate change sinks in, its long-term ramifications have introduced a new lexicon of psychological suffering related to the crisis.²⁷ Common terms for such distress include ecoanxiety (fear of what is happening and will happen with climate change), ecogrief (sadness about the destruction of species and natural habitats), solastalgia²⁸ (the nostalgia an individual feels for emotionally treasured landscapes that have changed), and terrafuria or ecorage (the reaction to betrayal and inaction by governments and leaders).²⁹ Climate-related emotions can lead to pessimism about the future and a nihilistic outlook on an individual’s ability to effect change and have agency over their life’s outcomes.

The categories of direct and indirect impacts are not mutually exclusive. A child may be starving due to weather-related crop failure as the family is forced to move to another country, then have to contend with prejudice and bullying as an immigrant, and later become anxiously preoccupied with climate change and its ability to cause further distress.

Effect on individuals with serious mental illness

Patients with SMI are particularly vulnerable to the impact of climate change. They are less resilient to climate change–related events, such as heat waves or temporary displacement from flooding, both at the personal level due to illness factors (eg, negative symptoms or cognitive impairment) and at the community level due to social factors (eg, weaker social support or poverty).

Recognizing the increased vulnerability to heat waves and preparing for them is particularly important for patients with SMI because they are at an increased risk for heat-related illnesses.³⁰ For example, patients may not appreciate the danger from heat and live in conditions that put them at risk (ie, not having air conditioning in their home or living alone). Their illness alone impairs heat regulation³¹; patients with depression and anxiety also dissipate heat less effectively.^32,33 Additionally, many psychiatric medications, particularly antipsychotics, impair key mechanisms of heat dissipation.^34,35 Antipsychotics render organisms more poikilothermic (susceptible to environmental temperature, like cold-blooded animals) and can be anticholinergic, which impedes sweating. A recent analysis of heat-related deaths during a period of extreme and prolonged heat in British Columbia in 2021 affirmed these concerns, reporting that patients with schizophrenia had the highest odds of death during this heat-related event.³⁶

COVID-19 has shown that flexible models of care are needed to prevent disengagement from medical and psychiatric care³⁷ and assure continued treatment with essential medications such as clozapine³⁸ and long-acting injectable antipsychotics³⁹ during periods of social change, as with climate change. While telehealth was critical during the COVID-19 pandemic⁴⁰ and is here to stay, it alone may be insufficient given the digital divide (patients with SMI may be less likely to have access to or be proficient in the use of digital technologies). The pandemic has shown the importance of public health efforts, including benefits from targeted outreach, with regards to vaccinations for this patient group.^41,42Table 2 summarizes things clinicians should consider when preparing patients with SMI for the effects of climate change.

Continue to: The psychiatrist's role

There are many ways a psychiatrist can professionally get involved in addressing climate change. Table 3^43-53 outlines the 3 Ps of climate action (taking actions to mitigate the effects of climate change): personal, patient (and clinic), and political (advocacy).

Personal

Even if clinicians believe climate change is important for their clinical work, they may still feel overwhelmed and unsure what to do in the context of competing responsibilities. A necessary first step is overcoming paralysis from the enormity of the problem, including the need to shift away from an expanding consumption model to environmental sustainability in a short period of time.

A good starting point is to get educated on the facts of climate change and how to discuss it in an office setting as well as in your personal life. A basic principle of climate change communication is that constructive hope (progress achieved despite everything) coupled with constructive doubt (the reality of the threat) can mobilize people towards action, whereas false hope or fatalistic doubt impedes action.⁴³ The importance of optimal public health messaging cannot be overstated; well-meaning campaigns to change behavior can fail if they emphasize the wrong message. For example, in a study examining COVID-19 messaging in >80 countries, Dorison et al⁴⁴ found that negatively framed messages mostly increased anxiety but had no benefit with regard to shifting people toward desired behaviors. The best public health messages are brief, repeated, and delivered by a trusted person.⁴⁵ Good messages are targeted to a concrete concern and where action would pay off now and not in some distant future.

In addition, clinicians can learn how to confront climate disavowal and difficult emotions in themselves and even plan to shift to carbon neutrality, such as purchasing carbon offsets or green sources of energy and transportation. They may not be familiar with principles of disaster preparedness or crisis communication.⁴⁶ Acquiring those professional skills may suggest next steps for action. Being familiar with the challenges and resources for immigrants, including individuals displaced due to climate change, may be necessary.⁴⁷ Finally, to reduce the risk of burnout, it is important to practice self-care, including strategies to reduce feelings of being overwhelmed.

Patient

In clinical encounters, clinicians can be proactive in helping patients understand their climate-related anxieties around an uncertain future, including identifying barriers to climate action.⁴⁸Emphasizing that climate action has health benefits for them and their communities now (eg, less polluted air leading to fewer health problems related to pollution) may engage patients unsure about their role in the fight against climate change. This simple message overcomes the human preference for immediate and concrete benefits over investment in long-term gains. Some patients may respond to the suggestion that adopting a plant-based diet is beneficial for their own health as well as for planetary health, given the substantial contribution of animal farming to global warming.⁴⁹

Continue to: Clinics must prepare for disasters...

Clinics must prepare for disasters in their communities to prevent disruption of psychiatric care by having an action plan, including the provision of medications. Such action plans should be prioritized for the most likely scenarios in an individual’s setting (eg, heat waves, wildfires, hurricanes, or flooding).

It is important to educate clinic staff and include them in planning for emergencies, because an all-hands approach and buy-in from all team members is critical. Clinicians should review how patients would continue to receive services, particularly medications, in the event of a disaster. In some cases, providing a 90-day medication supply will suffice, while in others (eg, patients receiving long-acting antipsychotics or clozapine) more preparation is necessary. Some events are predictable and can be organized annually, such as clinicians becoming vaccine ambassadors and organizing vaccine campaigns every fall⁵⁰; winter-related disaster preparation every fall; and heat wave education every spring (leaflets for patients, staff, and family members; review of safety of medications during heat waves). Plan for, monitor, and coordinate medical care and services for climate refugees and other populations that may otherwise delay medical care and impede illness prevention. Finally, support climate refugees, including connecting them to services or providing trauma-informed care.

Political

Some clinicians may feel compelled to become politically active to advocate for changes within the health care system. Two initiatives related to decarbonizing the health care sector are My Green Doctor⁵¹ and Health Care Without Harm,⁵² which offer help in shifting your office, clinic, or hospital towards carbon neutrality.

Climate change unevenly affects people and will continue to exacerbate inequalities in society, including individuals with mental illness.⁵³ To work toward climate justice on behalf of their patients, clinicians could join (or form) climate committees of special interest groups in their professional organizations or setting. Joining like-minded groups working on climate change at the local or national level prevents an omission of a psychiatric voice and counteracts burnout. It is important to stay focused on the root causes of the problem during activism: doing something to reduce fossil fuel use is ultimately most important.⁵⁴ The concrete goal of reaching the Paris 1.5-degree Celsius climate goal is a critical benchmark against which any other action can be measured.⁵⁴

Planning for the future

Over the course of history, societies have always faced difficult periods in which they needed to rebuild after natural disasters or self-inflicted catastrophes such as terrorist attacks or wars. Since the advent of the nuclear age, people have lived under the existential threat of nuclear war. The Anthropocene is a proposed geological term that reflects the enormous and possibly disastrous impact human activity has had on our planet.⁵⁵ While not yet formally adopted, this term has heuristic value, directing attention and reflection to our role and its now undisputed consequences. In the future, historians will debate if the scale of our current climate crisis has been different. It is, however, not controversial that humanity will be faced with the effects of climate change for the foreseeable future.¹⁰ Already, even “normal” weather events are fueled by energy in overcharged and altered weather systems due to global warming, leading to weather events ranging from droughts to floods and storms that are more severe, more frequent, and have longer-lasting effects on communities.⁵⁶

Continue to: As physicians, we are tasked...

As physicians, we are tasked by society to create and maintain a health care system that addresses the needs of our patients and the communities in which they live. Increasingly, we are forced to contend with an addition to the traditional 5 phases of acute disaster management (prevention, mitigation, preparedness, response, and recovery) to manage prolonged or even parallel disasters, where a series of disasters occurs before the community has recovered and healed. We must grapple with a sense of an “extended period of insecurity and instability” (permacrisis) and must better prepare for and prevent the polycrisis (many simultaneous crises) or the metacrisis of our “age of turmoil”⁵⁷ in which we must limit global warming, mitigate its damage, and increase community resilience to adapt.

Leading by personal example and providing hope may be what some patients need, as the reality of climate change contributes to the general uneasiness about the future and doomsday scenarios to which many fall victim. At the level of professional societies, many are calling for leadership, including from mental health organizations, to bolster the “social climate,” to help us strengthen our emotional resilience and social bonds to better withstand climate change together.⁵⁸ It is becoming harder to justify standing on the sidelines,⁵⁹ and it may be better for both our world and a clinician’s own sanity to be engaged in professional and private hopeful action¹ to address climate change. Without ecological or planetary health, there can be no mental health.

Bottom Line

Clinicians can prepare their patients for climate-related disruptions and manage the impact climate change has on their mental health. Addressing climate change at clinical and political levels is consistent with the leadership roles and professional ethics clinicians face in daily practice.

As a result of the coronavirus disease 2019 (COVID-19) pandemic, the content of outpatient psychotherapy and psychopharmacology sessions has seen significant change, with many patients focusing on how the pandemic has altered their daily lives and emotional well-being. Most patients were suddenly limited in both the amount of time they spent, and in their interactions with people, outside of their homes. Additionally, employment-related stressors such as working from home and the potential loss of a job and/or income added to pandemic stress.¹ Patients simultaneously processed their experiences of the COVID-19 pandemic while often striving to adapt to new virtual modes of mental health care delivery via phone or video conferencing.

The clinic staff at our large, multidisciplinary, urban outpatient mental health practice conducts weekly case consultation meetings. In meetings held during the early stages of the COVID-19 pandemic, we noted 4 dominant clinical themes emerging across our patients’ experiences:

• isolation
• uncertainty
• household stress
• grief.

These themes occurred across many diagnostic categories, suggesting they reflect a dramatic shift brought on by the pandemic. Our group compared clinical experiences from the beginning of the pandemic through the end of May 2020. For this article, we considered several patients who expressed these 4 themes and created a “composite patient.” In the following sections, we describe the typical presentation of, and recommended interventions for, a composite patient for each of these 4 themes.

Isolation

Mr. J, a 60-year-old, single, African American man diagnosed with bipolar disorder with psychotic features, lives alone in an apartment in a densely populated area. Before COVID-19, he had been attending a day treatment program. His daily walks for coffee and cigarettes provided the scaffolding to his emotional stability and gave him a sense of belonging to a world outside of his home. Mr. J also had been able to engage in informal social activities in the common areas of his apartment complex.

The start of the COVID-19 pandemic ends his interpersonal interactions, from the passive and superficial conversations he had with strangers in coffee shops to the more intimate engagement with his peers in his treatment program. The common areas of Mr. J’s apartment building are closed, and his routine cigarette breaks with neighbors have become solitary events, with the added stress of having to schedule his use of the building’s designated smoking area. Before COVID-19, Mr. J had been regularly meeting his brother for coffee to talk about the recent death of their father, but these meetings end due to infection concerns by Mr. J and his brother, who cares for their ailing mother who is at high risk for COVID-19 infection.

Mr. J begins to report self-referential ideation when walking in public, citing his inability to see peoples’ facial expressions because they are wearing masks. As a result of the pandemic restrictions, he becomes depressed and develops increased paranoid ideation. Fortunately, Mr. J begins to participate in a virtual partial hospitalization program to address his paranoid ideation through intensive and clinically-based social interactions. He is unfamiliar with the technology used for virtual visits, but is given the necessary technical support. He is also able to begin virtual visits with his brother and mother. Mr. J soon reports his symptoms are reduced and his mood is more stable.

Engaging in interpersonal interactions can have a positive impact on mental health. Social isolation has demonstrated negative effects that are amplified in individuals with psychiatric disorders.² Interpersonal interactions can provide a shared experience, promote positive feelings of social connection, and aid in the development of social skills.^3,4 Among our patients, we have begun to see the effects of isolation manifest as loneliness and demoralization.

Continue to: Interventions

Interventions. Due to restrictions imposed to limit the spread of COVID-19, evidence-based interventions such as meeting a friend for a meal or participating in in-person support groups typically are not options, thus forcing clinicians to accommodate, adapt, and use technology to develop parallel interventions to provide the same therapeutic effects.^5,6 These solutions need to be individualized to accommodate each patient’s unique social and clinical situation (Table 1). Engaging through technology can be problematic for patients with psychosis and paranoid ideation, or those with depressive symptoms. Psychopharmacology or therapy visit time has to be dedicated to helping patients become comfortable and confident when using technology to access their clinicians. Patients can use this same technology to establish virtual social connections. Providing patients with accurate, factual information about infection control during clinical visits ultimately supports their mental health. Delivering clinical care during COVID-19 has required creativity and flexibility to optimize available resources and capitalize on patients’ social supports. These strategies help decrease isolation, loneliness, and exacerbation of psychiatric symptoms.

Uncertainty

Ms. L, age 42, has a history of posttraumatic stress disorder and obstructive sleep apnea, for which she uses a continuous airway positive pressure (CPAP) device. She had been working as a part-time nanny when her employer furloughed her early in the COVID-19 pandemic. Her anxiety has gotten worse throughout the quarantine; she fears her unemployment benefits will run out and she will lose her job. Her anxiety manifests as somatic “pit-of-stomach” sensations. Her sleep has been disrupted; she reports more frequent nightmares, and her partner says that Ms. L has had apneic episodes and bruxism. The parameters of Ms. L’s CPAP device need to be adjusted, but a previously scheduled overnight polysomnography test is deemed a nonessential procedure and canceled. Ms. L has been reluctant to go to a food pantry because she is afraid of being exposed to COVID-19. In virtual sessions, Ms. L says she is uncertain if she will be able to pay her rent, buy food, or access medical care, and expresses overriding helplessness.

During COVID-19, anxiety and insomnia are driven by the sudden manifestation of uncertainty regarding being able to work, pay rent or mortgage, buy food and other provisions, or visit family and friends, including those who are hospitalized or live in nursing homes. Additional uncertainties include how long the quarantine will last, who will become ill, and when, or if, life will return to normal. Taken together, these uncertainties impart a pervasive dread to daily experience.

Interventions. Clinicians can facilitate access to services (eg, social services, benefits specialists) and help patients parse out what they should and can address practically, and which challenges are outside of their personal or communal control (Table 2). Patients can be encouraged to identify paralytic rumination and shift their mental focus to engage in constructive projects. They can be advised to limit their intake of media that increases their anxiety and replace it with phone calls or e-mails to family and friends. Scheduled practice of mindfulness meditation and diaphragmatic breathing can help reduce anxiety.^7,8 Pharmacotherapeutic interventions should be low-risk to minimize burdening emergency departments saturated with patients who have COVID-19 and serve to reduce symptoms that interfere with behavioral activation. While the research on benzodiazepines and non-benzodiazepine receptor agonists (“Z-drugs” such as zolpidem and eszopiclone) in the setting of obstructive sleep apnea is complex, and there is some evidence that the latter may not exacerbate apnea,⁹ benzodiazepines and Z-drugs are associated with an array of risks, including tolerance, withdrawal, and traumatic falls, particularly in older adults.¹⁰ Sleep hygiene and cognitive-behavioral therapy are first-line therapies for insomnia.¹¹

Household stress

Ms. M, a 45-year-old single mother with a history of generalized anxiety disorder, is suddenly thrust into homeschooling her 2 children, ages 10 and 8, while trying to remain productive at her job as a software engineer. She no longer has time for herself, and spends much of her day helping her children with schoolwork or planning activities to keep them engaged rather than arguing with each other. She feels intense pressure, heightened stress, and increased anxiety as she tries to navigate this new daily routine.

Continue to: New household dynamics...

New household dynamics abound when people are suddenly forced into atypical routines. In the context of COVID-19, working parents may be forced to balance the demands of their jobs with homeschooling their children. Couples may find themselves arguing more frequently. Adult children may find themselves needing to care for their ill parents. Limited space, a lack of leisure activities, and uncertainty about the future coalesce to increase conflict and stress. Research suggests that how people cope with a stressor is a more reliable determinant of health and well-being than the stressor itself.¹²

Interventions. Mental health clinicians can offer several recommendations to help patients cope with increased household stress (Table 3). We can encourage patients to have clear communication with their loved ones regarding new expectations, roles, and their feelings. Demarcating specific areas within living spaces to each person in the household can help each member feel a sense of autonomy, regardless of how small their area may be. Clinicians can help patients learn to take the time as a family to work on establishing new household routines. Telepsychiatry offers clinicians a unique window into patients’ lives and family dynamics, and we can use this perspective to deepen our understanding of the patient’s context and household relationships and help them navigate the situation thrust upon them.

Grief

Following a psychiatric hospitalization for an acute exacerbation of psychosis, Ms. S, age 79, is transferred to a rehabilitation facility, where she contracts COVID-19. Because Ms. S did not have a history of chronic medical illness, her family anticipates a full recovery. Early in the course of Ms. S’s admission, the rehabilitation facility restricts visitations, and her family is unable to see her. Ms. S dies in this facility without her family’s presence and without her family having the opportunity to say goodbye. Ms. S’s psychiatrist offers her family a virtual session to provide support. During the virtual session, the psychiatrist notes signs of complicated bereavement among Ms. S’s family members, including nonacceptance of the death, rumination about the circumstances of the death, and describing life as having no purpose.

The COVID-19 pandemic has complicated the natural process of loss and grief across multiple dimensions. Studies have shown that an inability to say goodbye before death, a lack of social support,¹³ and a lack of preparation for loss¹⁴ are associated with complicated bereavement and depression. Many people are experiencing the loss of loved ones without having a chance to appropriately mourn. Forbidding visits to family members who are hospitalized also prevents the practice of religious and spiritual rituals that typically occur at the end of life. This is worsened by truncated or absent funeral services. Support for those who are grieving may be offered from a distance, if at all. When surviving family members have been with the deceased prior to hospitalization, they may be required to self-quarantine, potentially exacerbating their grief and other symptoms associated with loss.

Interventions. Because social support is a protective factor against complicated grief,¹⁴ there are several recommendations for survivors as they work through the process of grief (Table 4). These include preparing families for a potential death; discussing desired spiritual and memorial services¹⁵; connecting families to resources such as community grief support programs, counseling/therapy, funeral services, video conferencing, and other communication tools; and planning for additional support for surviving family and friends, both immediately after the death and in the long term. It is also important to provide appropriate counseling and support for surviving family members to focus on their own well-being by exercising, eating nutritious meals, getting enough sleep, and abstaining from alcohol and drugs of abuse.¹⁶

Continue to: An ongoing challenge

Our clinical team recommends further investigation to define additional psycho­therapeutic themes arising from the COVID-19 pandemic and provide evidence-based interventions to address these categories, which we expect will increase in clinical salience in the months and years ahead. Close monitoring, follow-up by clinical and research staff, and evidence-based interventions will help address these dominant themes, with the goal of alleviating patient suffering.

Bottom Line

Our team identified 4 dominant clinical themes emerging across our patients’ experiences during the coronavirus disease 2019 pandemic: isolation, uncertainty, household stress, and grief. Clinicians can implement specific interventions to reduce the impact of these themes, which we expect to remain clinically relevant in the upcoming months and years.

Close monitoring, follow-up by clinical and research staff, and evidence-based interventions will help address these dominant themes, with the goal of alleviating patient suffering.

Bottom Line

Our team identified 4 dominant clinical themes emerging across our patients’ experiences during the coronavirus disease 2019 pandemic: isolation, uncertainty, household stress, and grief. Clinicians can implement specific interventions to reduce the impact of these themes, which we expect to remain clinically relevant in the upcoming months and years.

As a result of the coronavirus disease 2019 (COVID-19) pandemic, the content of outpatient psychotherapy and psychopharmacology sessions has seen significant change, with many patients focusing on how the pandemic has altered their daily lives and emotional well-being. Most patients were suddenly limited in both the amount of time they spent, and in their interactions with people, outside of their homes. Additionally, employment-related stressors such as working from home and the potential loss of a job and/or income added to pandemic stress.¹ Patients simultaneously processed their experiences of the COVID-19 pandemic while often striving to adapt to new virtual modes of mental health care delivery via phone or video conferencing.

The clinic staff at our large, multidisciplinary, urban outpatient mental health practice conducts weekly case consultation meetings. In meetings held during the early stages of the COVID-19 pandemic, we noted 4 dominant clinical themes emerging across our patients’ experiences:

• isolation
• uncertainty
• household stress
• grief.

These themes occurred across many diagnostic categories, suggesting they reflect a dramatic shift brought on by the pandemic. Our group compared clinical experiences from the beginning of the pandemic through the end of May 2020. For this article, we considered several patients who expressed these 4 themes and created a “composite patient.” In the following sections, we describe the typical presentation of, and recommended interventions for, a composite patient for each of these 4 themes.

Isolation

Mr. J, a 60-year-old, single, African American man diagnosed with bipolar disorder with psychotic features, lives alone in an apartment in a densely populated area. Before COVID-19, he had been attending a day treatment program. His daily walks for coffee and cigarettes provided the scaffolding to his emotional stability and gave him a sense of belonging to a world outside of his home. Mr. J also had been able to engage in informal social activities in the common areas of his apartment complex.

The start of the COVID-19 pandemic ends his interpersonal interactions, from the passive and superficial conversations he had with strangers in coffee shops to the more intimate engagement with his peers in his treatment program. The common areas of Mr. J’s apartment building are closed, and his routine cigarette breaks with neighbors have become solitary events, with the added stress of having to schedule his use of the building’s designated smoking area. Before COVID-19, Mr. J had been regularly meeting his brother for coffee to talk about the recent death of their father, but these meetings end due to infection concerns by Mr. J and his brother, who cares for their ailing mother who is at high risk for COVID-19 infection.

Mr. J begins to report self-referential ideation when walking in public, citing his inability to see peoples’ facial expressions because they are wearing masks. As a result of the pandemic restrictions, he becomes depressed and develops increased paranoid ideation. Fortunately, Mr. J begins to participate in a virtual partial hospitalization program to address his paranoid ideation through intensive and clinically-based social interactions. He is unfamiliar with the technology used for virtual visits, but is given the necessary technical support. He is also able to begin virtual visits with his brother and mother. Mr. J soon reports his symptoms are reduced and his mood is more stable.

Engaging in interpersonal interactions can have a positive impact on mental health. Social isolation has demonstrated negative effects that are amplified in individuals with psychiatric disorders.² Interpersonal interactions can provide a shared experience, promote positive feelings of social connection, and aid in the development of social skills.^3,4 Among our patients, we have begun to see the effects of isolation manifest as loneliness and demoralization.

Interventions. Due to restrictions imposed to limit the spread of COVID-19, evidence-based interventions such as meeting a friend for a meal or participating in in-person support groups typically are not options, thus forcing clinicians to accommodate, adapt, and use technology to develop parallel interventions to provide the same therapeutic effects.^5,6 These solutions need to be individualized to accommodate each patient’s unique social and clinical situation (Table 1). Engaging through technology can be problematic for patients with psychosis and paranoid ideation, or those with depressive symptoms. Psychopharmacology or therapy visit time has to be dedicated to helping patients become comfortable and confident when using technology to access their clinicians. Patients can use this same technology to establish virtual social connections. Providing patients with accurate, factual information about infection control during clinical visits ultimately supports their mental health. Delivering clinical care during COVID-19 has required creativity and flexibility to optimize available resources and capitalize on patients’ social supports. These strategies help decrease isolation, loneliness, and exacerbation of psychiatric symptoms.

Uncertainty

Ms. L, age 42, has a history of posttraumatic stress disorder and obstructive sleep apnea, for which she uses a continuous airway positive pressure (CPAP) device. She had been working as a part-time nanny when her employer furloughed her early in the COVID-19 pandemic. Her anxiety has gotten worse throughout the quarantine; she fears her unemployment benefits will run out and she will lose her job. Her anxiety manifests as somatic “pit-of-stomach” sensations. Her sleep has been disrupted; she reports more frequent nightmares, and her partner says that Ms. L has had apneic episodes and bruxism. The parameters of Ms. L’s CPAP device need to be adjusted, but a previously scheduled overnight polysomnography test is deemed a nonessential procedure and canceled. Ms. L has been reluctant to go to a food pantry because she is afraid of being exposed to COVID-19. In virtual sessions, Ms. L says she is uncertain if she will be able to pay her rent, buy food, or access medical care, and expresses overriding helplessness.

During COVID-19, anxiety and insomnia are driven by the sudden manifestation of uncertainty regarding being able to work, pay rent or mortgage, buy food and other provisions, or visit family and friends, including those who are hospitalized or live in nursing homes. Additional uncertainties include how long the quarantine will last, who will become ill, and when, or if, life will return to normal. Taken together, these uncertainties impart a pervasive dread to daily experience.

Interventions. Clinicians can facilitate access to services (eg, social services, benefits specialists) and help patients parse out what they should and can address practically, and which challenges are outside of their personal or communal control (Table 2). Patients can be encouraged to identify paralytic rumination and shift their mental focus to engage in constructive projects. They can be advised to limit their intake of media that increases their anxiety and replace it with phone calls or e-mails to family and friends. Scheduled practice of mindfulness meditation and diaphragmatic breathing can help reduce anxiety.^7,8 Pharmacotherapeutic interventions should be low-risk to minimize burdening emergency departments saturated with patients who have COVID-19 and serve to reduce symptoms that interfere with behavioral activation. While the research on benzodiazepines and non-benzodiazepine receptor agonists (“Z-drugs” such as zolpidem and eszopiclone) in the setting of obstructive sleep apnea is complex, and there is some evidence that the latter may not exacerbate apnea,⁹ benzodiazepines and Z-drugs are associated with an array of risks, including tolerance, withdrawal, and traumatic falls, particularly in older adults.¹⁰ Sleep hygiene and cognitive-behavioral therapy are first-line therapies for insomnia.¹¹

Household stress

Ms. M, a 45-year-old single mother with a history of generalized anxiety disorder, is suddenly thrust into homeschooling her 2 children, ages 10 and 8, while trying to remain productive at her job as a software engineer. She no longer has time for herself, and spends much of her day helping her children with schoolwork or planning activities to keep them engaged rather than arguing with each other. She feels intense pressure, heightened stress, and increased anxiety as she tries to navigate this new daily routine.

Continue to: New household dynamics...

New household dynamics abound when people are suddenly forced into atypical routines. In the context of COVID-19, working parents may be forced to balance the demands of their jobs with homeschooling their children. Couples may find themselves arguing more frequently. Adult children may find themselves needing to care for their ill parents. Limited space, a lack of leisure activities, and uncertainty about the future coalesce to increase conflict and stress. Research suggests that how people cope with a stressor is a more reliable determinant of health and well-being than the stressor itself.¹²

Interventions. Mental health clinicians can offer several recommendations to help patients cope with increased household stress (Table 3). We can encourage patients to have clear communication with their loved ones regarding new expectations, roles, and their feelings. Demarcating specific areas within living spaces to each person in the household can help each member feel a sense of autonomy, regardless of how small their area may be. Clinicians can help patients learn to take the time as a family to work on establishing new household routines. Telepsychiatry offers clinicians a unique window into patients’ lives and family dynamics, and we can use this perspective to deepen our understanding of the patient’s context and household relationships and help them navigate the situation thrust upon them.

Grief

Following a psychiatric hospitalization for an acute exacerbation of psychosis, Ms. S, age 79, is transferred to a rehabilitation facility, where she contracts COVID-19. Because Ms. S did not have a history of chronic medical illness, her family anticipates a full recovery. Early in the course of Ms. S’s admission, the rehabilitation facility restricts visitations, and her family is unable to see her. Ms. S dies in this facility without her family’s presence and without her family having the opportunity to say goodbye. Ms. S’s psychiatrist offers her family a virtual session to provide support. During the virtual session, the psychiatrist notes signs of complicated bereavement among Ms. S’s family members, including nonacceptance of the death, rumination about the circumstances of the death, and describing life as having no purpose.

The COVID-19 pandemic has complicated the natural process of loss and grief across multiple dimensions. Studies have shown that an inability to say goodbye before death, a lack of social support,¹³ and a lack of preparation for loss¹⁴ are associated with complicated bereavement and depression. Many people are experiencing the loss of loved ones without having a chance to appropriately mourn. Forbidding visits to family members who are hospitalized also prevents the practice of religious and spiritual rituals that typically occur at the end of life. This is worsened by truncated or absent funeral services. Support for those who are grieving may be offered from a distance, if at all. When surviving family members have been with the deceased prior to hospitalization, they may be required to self-quarantine, potentially exacerbating their grief and other symptoms associated with loss.

Interventions. Because social support is a protective factor against complicated grief,¹⁴ there are several recommendations for survivors as they work through the process of grief (Table 4). These include preparing families for a potential death; discussing desired spiritual and memorial services¹⁵; connecting families to resources such as community grief support programs, counseling/therapy, funeral services, video conferencing, and other communication tools; and planning for additional support for surviving family and friends, both immediately after the death and in the long term. It is also important to provide appropriate counseling and support for surviving family members to focus on their own well-being by exercising, eating nutritious meals, getting enough sleep, and abstaining from alcohol and drugs of abuse.¹⁶
