Climate change is causing intense heat waves that threaten human health across the globe.¹ Given their unique biological, behavioral, and social factors, patients with serious mental illness (SMI)—which includes schizophrenia spectrum disorders, bipolar disorder, and severe depression—are at higher risk of developing and dying from heat-related illnesses such as heat exhaustion and heat stroke.¹ In this article, we discuss factors that increase the risk of heat-related illnesses in patients with SMI and outline steps you can take to educate and prepare patients for heat waves.

A confluence of factors increases risk

Thermoregulatory dysfunction is thought to be intrinsic to patients with schizophrenia partly due to dysregulated dopaminergic neurotransmission.² This is compounded by these patients’ higher burden of chronic medical comorbidities such as cardiovascular and respiratory illnesses, which together with psychotropic (ie, antipsychotics, antidepressants, lithium, benzodiazepines) and medical medications (ie, certain antihypertensives, diuretics, treatment for urinary incontinence) further disrupt the body’s cooling strategies and increase vulnerability to heat-related illnesses.^1,3 Antipsychotics commonly prescribed to patients with SMI increase hyperthermia risk largely by 2 mechanisms: central and peripheral thermal dysregulation, and anticholinergic properties (ie, olanzapine, clozapine, chlorpromazine).^2,3 Other anticholinergic medications prescribed to treat extrapyramidal symptoms (ie, diphenhydramine, benztropine, trihexyphenidyl), anxiety, depression, and insomnia (ie, paroxetine, trazodone, doxepin) further add insult to injury because they impair sweating, which decreases the body’s ability to eliminate heat through evaporation.^2,3 Additionally, high temperature exacerbates psychiatric symptoms in patients with SMI, resulting in increased hospitalizations and emergency department visits.¹ Patients with SMI also commonly have cognitive deficits, which may interfere with their ability to prepare for extreme heat and make it difficult for them to protect themselves. Finally, patients with SMI often have lower socioeconomic status with reduced access to air conditioning.^1,2

How to keep patients safe

The acronym HEAT provides a framework that psychiatrists can use to highlight the importance of planning for heat waves in their institution and guiding discussions with individual patients about heat-related illnesses (Table 1).

Help the health care system where you work plan and prepare for heat waves. In-service training in mental health settings such as outpatient clinics, shelters, group homes, and residential programs can help staff identify patients at particular risk and reinforce key prevention messages.

Educate patients and their caregivers on strategies for preventing heat-related illness. Informational materials can be distributed in clinics, residential settings, and day programs. A 1-page downloadable pamphlet available at https://smiadviser.org/wp-content/uploads/2022/08/SMI-Heat-Stroke-ver1.0-FINAL.pdf summarizes key prevention messages of staying hydrated, staying cool, and staying safe.

Assess personalized heat-related risks. Inquire about patients’ daily activities, access to air conditioning, and water intake. Minimize the use of anticholinergic medications. Identify who patients can turn to for assistance, especially for those who struggle with cognitive impairment and social isolation.

Teach patients, caregivers, and staff the signs and symptoms of heat exhaustion and heat stroke and how to respond in such situations.

HEAT focuses psychiatric clinicians on preparing and protecting patients with SMI against dangerous heat waves. Clinicians can take a proactive leadership role in disseminating basic principles of heat-related illness prevention and heat-wave toolkits by using resources available from organizations such as the Climate Psychiatry Alliance (Table 2). They can also initiate advocacy efforts to raise awareness about the elevated risks of heat-related illnesses in this vulnerable population.

After more than 600,000 deaths in the United States from the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), several safe and effective vaccines against the virus have become available. Vaccines are the most effective preventive measure against COVID-19 and the most promising way to achieve herd immunity to end the current pandemic. However, obstacles to reaching this goal include vaccine skepticism, structural barriers, or simple inertia to get vaccinated. These challenges provide opportunities for psychiatrists to use their medical knowledge and expertise, applying behavior management techniques such as motivational interviewing and nudging to encourage their patients to get vaccinated. In particular, marginalized patients with serious mental illness (SMI), who are subject to disproportionately high rates of COVID-19 infection and more severe outcomes,¹ have much to gain if psychiatrists become involved in the COVID-19 vaccination campaign.

In this article, we define vaccine hesitancy and highlight what makes psychiatrists ideal vaccine ambassadors, given their unique skill set and longitudinal, trust-based connection with their patients. We expand on the particular vulnerabilities of patients with SMI, including structural barriers to vaccination that lead to health disparities and inequity. Finally, building on “The ABCs of successful vaccinations” framework published in Current Psychiatry March 2021,² we outline how psychiatrists can address vaccine misconceptions, employ effective communication strategies to build vaccine confidence, and help patients overcome structural barriers and get the COVID-19 vaccination. While we are currently focused on ending the COVID-19 pandemic, our broader mission as psychiatrists should be to become ambassadors for other vaccinations as well, such as the annual influenza vaccine.

What is vaccine hesitancy?

The World Health Organization (WHO) defines vaccine hesitancy as a “delay in acceptance or refusal of vaccines despite availability of vaccine services.”^3,4 Vaccine hesitancy occurs on a continuum ranging from uncertainty about accepting a vaccine to absolute refusal.^4,5 It involves a complex decision-making process driven by contextual, individual, and social influences, and vaccine-specific issues.⁴ In the “3C” model developed by the WHO Strategic Advisory Group of Experts (SAGE) Working Group, vaccine hesitancy is influenced by confidence (trust in vaccines, in the health care system, and in policy makers), complacency (lower perceived risk), and convenience (availability, affordability, accessibility, language and health literacy, appeal of vaccination program).⁴

In 2019, the WHO named vaccine hesitancy as one of the top 10 global health threats.³ Hesitancy to receive COVID-19 vaccines may be particularly high because of their rapid development. In addition, the tumultuous political environment that often featured inconsistent messaging about the virus, its dangers, and its transmission since the early days of the pandemic created widespread public confusion and doubt as scientific understandings evolved. “Anti-vaxxer” movements that completely rejected vaccine efficacy disseminated misinformation online. Followers of these movements may have such extreme overvalued ideas that any effort to persuade them otherwise with scientific evidence will accomplish very little.^6,7 Therefore, focusing on individuals who are “sitting on the fence” about getting vaccinated can be more productive because they represent a much larger group than those who adamantly refuse vaccines, and they may be more amenable to changing beliefs and behaviors.⁸

The US Census Bureau’s Household Pulse Survey asked, “How likely are you to accept the vaccine?”⁹ As of late June 2021, 11.4% of US adults reported they would “definitely not get a vaccine” or “probably not get a vaccine,” and that number increases to 16.9% when including those who are “unsure,” although there is wide geographical variability.¹⁰

A recent study in Denmark showed that willingness to receive the COVID-19 vaccine was slightly lower among patients with mental illness (84.8%) compared with the general population (89.5%).¹¹ Given the small difference, vaccine hesitancy was not considered to be a major barrier for vaccination among patients with mental illness in Denmark. This is similar to the findings of a pre-pandemic study at a community mental health clinic in the United States involving other vaccinations, which suggested that 84% of patients with SMI perceived vaccinations as safe, effective, and important.¹² In this clinic, identified barriers to vaccinations in general among patients with SMI included lack of awareness and knowledge (42.2%), accessibility (16.3%), personal cost (13.3%), fears about immunization (10.4%), and lack of recommendations by primary care providers (PCPs) (1.5%).¹²

It is critical to distinguish attitude-driven vaccine hesitancy from a lack of education and opportunity to receive a vaccine. Particularly disadvantaged communities may be mislabeled as “vaccine hesitant” when in fact they may not have the ability to be as proactive as other population groups (eg, difficulty scheduling appointments over the Internet).

What makes psychiatrists ideal vaccine ambassadors?

There are several reasons psychiatrists can be well-positioned to contribute to the success of vaccination campaigns (Table 1). These include their frequent contact with patients and their care teams, the high trust those patients have in them, and their medical expertise and skills in applied behavioral and social science techniques, including motivational interviewing and nudging. Vaccination efforts and outreach are more effective when led by the clinician with whom the patient has the most contact because resolving vaccine hesitancy is not a one-time discussion but requires ongoing communication, persistence, and consistency.¹³ Patients may contact their psychiatrists more frequently than their other clinicians, including PCPs. For this reason, psychiatrists can serve as the gateway to health care, particularly for patients with SMI.¹⁴ In addition, interruptions in nonemergency services caused by the COVID-19 pandemic may affect vaccine delivery because patients may have been unable to see their PCPs regularly during the pandemic.¹⁵

Psychiatrists’ medical expertise and their ability to develop rapport with their patients promote trust-building. Receiving credible information from a trusted source such as a patient’s psychiatrist can be impactful. A recent poll suggested that individual health care clinicians have been consistently identified as the most trusted sources for vaccine information, including for the COVID-19 vaccines.¹⁶ There is also higher trust when there is greater continuity of care both in terms of length of time the patient has known the clinician and the number of consultations,¹⁷ an inherent part of psychiatric practice. In addition, research has shown that patients trust their psychiatrists as much as they trust their general practitioners.¹⁸

Psychiatrists are experts in behavior change, promoting healthy behaviors through motivational interviewing and nudging. They also have experience with managing patients who hold overvalued ideas as well as dealing with uncertainty, given their scientific and medical training.

Motivational interviewing is a patient-centered, collaborative approach widely used by psychiatrists to treat unhealthy behaviors such as substance use. Clinicians elicit and strengthen the patient’s desire and motivation for change while respecting their autonomy. Instead of presenting persuasive facts, the clinician creates a welcoming, nonthreatening, safe environment by engaging patients in open dialogue, reflecting back the patients’ concerns with empathy, helping them realize contradictions in behavior, and supporting self-sufficiency.¹⁹ In a nonpsychiatric setting, studies have shown the effectiveness of motivational interviewing in increasing uptake of human papillomavirus vaccines and of pediatric vaccines.²⁰

Nudging, which comes from behavioral economics and psychology, underscores the importance of structuring a choice architecture in changing the way people make their everyday decisions.²¹ Nudging still gives people a choice and respects autonomy, but it leads patients to more efficient and productive decision-making. Many nudges are based around giving good “default options” because people often do not make efforts to deviate from default options. In addition, social nudges are powerful, giving people a social reference point and normalizing certain behaviors.²¹ Psychiatrists have become skilled in nudging from working with patients with varying levels of insight and cognitive capabilities. That is, they give simple choices, prompts, and frequent feedback to reinforce “good” decisions and to discourage “bad” decisions.

Continue to: Managing overvalued ideas

Managing overvalued ideas. Psychiatrists are also well-versed in having discussions with patients who hold irrational beliefs (psychosis) or overvalued ideas. For example, psychiatrists frequently manage anorexia nervosa and hypochondria, which are rooted in overvalued ideas.⁷ While psychiatrists may not be able to directly confront the overvalued ideas, they can work around such ideas while waiting for more flexible moments. Similarly, managing patients with intense emotional commitment⁷ to commonly held anti-vaccination ideas may not be much different. Psychiatrists can work around resistance until patients may be less strongly attached to those overvalued ideas in instances when other techniques, such as motivational interviewing and nudging, may be more effective.

Managing uncertainty. Psychiatrists are experts in managing “not knowing” and uncertainty. Due to their medical scientific training, they are familiar with the process of science, and how understanding changes through trial and error. In contrast, most patients usually only see the end product (ie, a drug comes to market). Discussions with patients that acknowledge uncertainty and emphasize that changes in what is known are expected and appropriate as scientific knowledge evolves could help preempt skepticism when messages are updated.
 

Why do patients with SMI need more help?

SMI as a high-risk group. Patients with SMI are part of a “tragic” epidemiologic triad of agent-host-environment¹⁵ that places them at remarkably elevated risk for COVID-19 infection and more serious complications and death when infected.¹ After age, a diagnosis of a schizophrenia spectrum disorder is the second largest predictor of mortality from COVID-19, with a 2.7-fold increase in mortality.²² This is how the elements of the triad come together: SARS-Cov-2 is a highly infectious agent affecting individuals who are vulnerable hosts because of their high frequency of medical comorbidities, including cardio­vascular disease, type 2 diabetes, and respiratory tract diseases, which are all risk factors for worse outcomes due to COVID-19.²³ In addition, SMI is associated with socioeconomic risk factors for SARS-Cov-2 infection, including poverty, homelessness, and crowded settings such as jails, group homes, hospitals, and shelters, which constitute ideal environments for high transmission of the virus.

Structural barriers to vaccination. Studies have suggested lower rates of vaccination among people with SMI for various other infectious diseases compared with the general population.¹² For example, in 1 outpatient mental health setting, influenza vaccination rates were 24% to 28%, which was lower than the national vaccination rate of 40.9% for the same influenza season (2010 to 2011).²⁴ More recently, a study in Israel examining the COVID-19 vaccination rate among >25,000 patients with schizophrenia suggested under-vaccination of this cohort. The results showed that the odds of getting the COVID-19 vaccination were significantly lower in the schizophrenia group compared with the general population (odds ratio = 0.80, 95% CI: 0.77 to 0.83).²⁵

Patients with SMI encounter considerable system-level barriers to vaccinations in general, such as reduced access to health care due to cost and a lack of transportation,¹² the digital divide given their reduced access to the internet and computers for information and scheduling,²⁶ and lack of vaccination recommendations from their PCPs.¹² Studies have also shown that patients with SMI often receive suboptimal medical care because of stigmatization and discrimination.²⁷ They also have lower rates of preventive care utilization, seeking medical services only in times of crisis and seeking mental health services more often than physical health care.^28-30

Continue to: Patients with SMI face...

Patients with SMI face additional individual challenges that impede vaccine uptake, such as lack of knowledge and awareness about the virus and vaccinations, general cognitive impairment, low digital literacy skills,³¹ low language literacy and educational attainment, baseline delusions, and negative symptoms such as apathy, avolition, and anhedonia.¹ Thus, even if they overcome the external barriers and obtain vaccine-related information, these patients may experience difficulty in understanding the content and applying this information to their personal circumstances as a result of low health literacy.

How psychiatrists can help

The concept of using mental health care sites and trained clinicians to increase medical disease prevention is not new. The rigorously tested intervention model STIRR (Screen, Test, Immunize, Reduce risk, and Refer) uses co-located nurse practitioners in community mental health centers to provide risk assessment, counseling, and blood testing for hepatitis and HIV, as well as on-site vaccinations for hepatitis to patients dually diagnosed with SMI and substance use disorders.³² Similarly, when a vaccination program was integrated into an outpatient mental health clinic offering various on-site vaccinations, vaccination rates increased by up to 25% over baseline.¹² Such public health approaches of integrating medical care at the site of mental health care, where patients with SMI are most reliably engaged, can be highly cost-effective³³ in terms of reducing disease burden among patients with SMI.

While the psychiatrist may not have the time and resources to directly follow through on all aspects of vaccinations, they can assume leadership and work with the larger team—including therapists and counselors, nurse practitioners, social workers, case managers, care coordinators, or PCPs with whom they regularly collaborate in caring for patients with SMI—to communicate what they have learned about patient hesitancies, share suggestions for future conversations to address these hesitancies, and relay what structural barriers the patient may need assistance to address.

Prioritization of patients with SMI for vaccine eligibility does not directly lead to vaccine uptake. Patients with SMI need extra support from their primary point of health care contact, namely their psychiatrists. Psychiatrists may bring a set of specialized skills uniquely suited to this moment to address vaccine hesitancy and overall lack of vaccine resources and awareness. Freudenreich et al² recently proposed “The ABCs of Successful Vaccinations” framework that psychiatrists can use in their interactions with patients to encourage vaccination by focusing on:

• attitudes towards vaccination
• barriers to vaccination
• completed vaccination series.

Understand attitudes toward vaccination. Decision-making may be an emotional and psychological experience that is informed by thoughts and feelings,³⁴ and psychiatrists are uniquely positioned to tailor messages to individual patients by using motivational interviewing and applying nudging techniques.⁸ Given the large role of the pandemic in everyday life, it would be natural to address vaccine-related concerns in the course of routine rapport-building. Table 2^19,34-38 shows example phrases of COVID-19 vaccine messages that are based on communication strategies that have demonstrated success in health behavior domains (including vaccinations).³⁹

Continue to: First, a strong recommendation...

First, a strong recommendation should be made using the presumptive approach.⁴⁰ If vaccine hesitancy is detected, psychiatrists should next attempt to understand patients’ reasoning with open-ended questions to probe vaccine-related concerns. Motivational interviewing can then be used to target the fence sitters (rather than anti-vaxxers).⁶ Psychiatrists can also communicate with therapists about the need for further follow up on patients’ hesitancies.

When assuring patients of vaccine safety and efficacy, it is helpful to explain the vaccine development process, including FDA approval, extensive clinical trials, monitoring, and the distribution process. Providing clear, transparent, accurate information about the risks and benefits of the vaccines is important, as well as monitoring misinformation and developing convincing counter messages that elicit positive emotions toward the vaccines.⁴¹ Examples of messages to counter common vaccine-related concerns and misinformation are shown in Table 3.^42-44

Know the barriers to vaccination. The role of the psychiatrist is to help patients, particularly those with SMIs, overcome logistical barriers and address hesitancy, which are both essential for vaccine uptake. Psychiatrists can help identify actual barriers (eg, transportation, digital access for information and scheduling) and perceived barriers, improve information access, and help patients obtain self-efficacy to take the actions needed to get vaccinated, particularly by collaborating with and communicating these concerns to other social services (Table 4).⁴¹

Monitor for vaccination series completion. Especially for vaccines that require more than a single dose over time, patients need more reminders, nudges, practical support, and encouragement to complete vaccination. A surprising degree of confusion regarding the timing of protection and benefit from the second COVID-19 injection (for the 2-injection vaccines) was uncovered in a recent survey of >1,000 US adults who had received their vaccinations in February 2021.⁴⁵ Attentive monitoring of vaccination series completion by psychiatrists can thus increase the likelihood that a patient will follow through (Table 4).⁴¹ This can be as simple as asking about completion of the series during appointments, but further aided by communicating to the larger care team (social workers, care managers, care coordinators) when identifying that the patient may need further assistance.

The Figure^2,6,7,19,40 summarizes the steps that psychiatrists can take to help patients get vaccinated by assessing attitudes towards vaccination (vaccine hesitancy), helping to remove barriers to vaccination, and ensuring via patient follow-up that a vaccine series is completed.

Continue to: Active involvement is key

Active involvement is key

The active involvement of psychiatrists in COVID-19 vaccination efforts can protect patients from the virus, reduce health disparities among patients with SMI, and promote herd immunity, helping to end the pandemic. Psychiatry practices can serve as ideal platforms to deliver evidence-based COVID-19 vaccine information and encourage vaccine uptake, particularly for marginalized populations.

Vaccination programs in mental health practices can even be conceptualized as a moral mandate in the spirit of addressing distributive injustice. The population management challenges of individual-level barriers and follow-through could be dramatically reduced—if not nearly eliminated—through policy-level changes that allow vaccinations to be administered in places where patients with SMI are already engaged: that is, “shots in arms” in mental health settings. As noted, some studies have shown that mental health settings can play a key role in other preventive care campaigns, such as the annual influenza and hepatitis vaccinations, and thus the incorporation of preventive care need not be limited to just COVID-19 vaccination efforts.

The COVID-19 pandemic is an opportunity to rethink the role of psychiatrists and psychiatric offices and clinics in preventive health care. The health risks and disparities of patients with SMI require the proactive involvement of psychiatrists at both the level of their individual patients and at the federal and state levels to advocate for policy changes that can benefit these populations. Overall, psychiatrists occupy a special role within the medical establishment that enables them to uniquely advocate for patients with SMI and ensure they are not forgotten during the COVID-19 pandemic.

Bottom Line

Psychiatrists could apply behavior management techniques such as motivational interviewing and nudging to address vaccine hesitancy in their patients and move them to accepting the COVID-19 vaccination. This could be particularly valuable for patients with serious mental illness, who face increased risks from COVID-19 and additional barriers to getting vaccinated.

Instead of presenting persuasive facts, the clinician creates a welcoming, nonthreatening, safe environment by engaging patients in open dialogue, reflecting back the patients’ concerns with empathy, helping them realize contradictions in behavior, and supporting self-sufficiency.¹⁹ In a nonpsychiatric setting, studies have shown the effectiveness of motivational interviewing in increasing uptake of human papillomavirus vaccines and of pediatric vaccines.²⁰

Nudging, which comes from behavioral economics and psychology, underscores the importance of structuring a choice architecture in changing the way people make their everyday decisions.²¹ Nudging still gives people a choice and respects autonomy, but it leads patients to more efficient and productive decision-making. Many nudges are based around giving good “default options” because people often do not make efforts to deviate from default options. In addition, social nudges are powerful, giving people a social reference point and normalizing certain behaviors.²¹ Psychiatrists have become skilled in nudging from working with patients with varying levels of insight and cognitive capabilities. That is, they give simple choices, prompts, and frequent feedback to reinforce “good” decisions and to discourage “bad” decisions.

Continue to: Managing overvalued ideas

Managing overvalued ideas. Psychiatrists are also well-versed in having discussions with patients who hold irrational beliefs (psychosis) or overvalued ideas. For example, psychiatrists frequently manage anorexia nervosa and hypochondria, which are rooted in overvalued ideas.⁷ While psychiatrists may not be able to directly confront the overvalued ideas, they can work around such ideas while waiting for more flexible moments. Similarly, managing patients with intense emotional commitment⁷ to commonly held anti-vaccination ideas may not be much different. Psychiatrists can work around resistance until patients may be less strongly attached to those overvalued ideas in instances when other techniques, such as motivational interviewing and nudging, may be more effective.

Managing uncertainty. Psychiatrists are experts in managing “not knowing” and uncertainty. Due to their medical scientific training, they are familiar with the process of science, and how understanding changes through trial and error. In contrast, most patients usually only see the end product (ie, a drug comes to market). Discussions with patients that acknowledge uncertainty and emphasize that changes in what is known are expected and appropriate as scientific knowledge evolves could help preempt skepticism when messages are updated.
 

Why do patients with SMI need more help?

SMI as a high-risk group. Patients with SMI are part of a “tragic” epidemiologic triad of agent-host-environment¹⁵ that places them at remarkably elevated risk for COVID-19 infection and more serious complications and death when infected.¹ After age, a diagnosis of a schizophrenia spectrum disorder is the second largest predictor of mortality from COVID-19, with a 2.7-fold increase in mortality.²² This is how the elements of the triad come together: SARS-Cov-2 is a highly infectious agent affecting individuals who are vulnerable hosts because of their high frequency of medical comorbidities, including cardio­vascular disease, type 2 diabetes, and respiratory tract diseases, which are all risk factors for worse outcomes due to COVID-19.²³ In addition, SMI is associated with socioeconomic risk factors for SARS-Cov-2 infection, including poverty, homelessness, and crowded settings such as jails, group homes, hospitals, and shelters, which constitute ideal environments for high transmission of the virus.

Structural barriers to vaccination. Studies have suggested lower rates of vaccination among people with SMI for various other infectious diseases compared with the general population.¹² For example, in 1 outpatient mental health setting, influenza vaccination rates were 24% to 28%, which was lower than the national vaccination rate of 40.9% for the same influenza season (2010 to 2011).²⁴ More recently, a study in Israel examining the COVID-19 vaccination rate among >25,000 patients with schizophrenia suggested under-vaccination of this cohort. The results showed that the odds of getting the COVID-19 vaccination were significantly lower in the schizophrenia group compared with the general population (odds ratio = 0.80, 95% CI: 0.77 to 0.83).²⁵

Patients with SMI encounter considerable system-level barriers to vaccinations in general, such as reduced access to health care due to cost and a lack of transportation,¹² the digital divide given their reduced access to the internet and computers for information and scheduling,²⁶ and lack of vaccination recommendations from their PCPs.¹² Studies have also shown that patients with SMI often receive suboptimal medical care because of stigmatization and discrimination.²⁷ They also have lower rates of preventive care utilization, seeking medical services only in times of crisis and seeking mental health services more often than physical health care.^28-30

Continue to: Patients with SMI face...

Patients with SMI face additional individual challenges that impede vaccine uptake, such as lack of knowledge and awareness about the virus and vaccinations, general cognitive impairment, low digital literacy skills,³¹ low language literacy and educational attainment, baseline delusions, and negative symptoms such as apathy, avolition, and anhedonia.¹ Thus, even if they overcome the external barriers and obtain vaccine-related information, these patients may experience difficulty in understanding the content and applying this information to their personal circumstances as a result of low health literacy.

How psychiatrists can help

The concept of using mental health care sites and trained clinicians to increase medical disease prevention is not new. The rigorously tested intervention model STIRR (Screen, Test, Immunize, Reduce risk, and Refer) uses co-located nurse practitioners in community mental health centers to provide risk assessment, counseling, and blood testing for hepatitis and HIV, as well as on-site vaccinations for hepatitis to patients dually diagnosed with SMI and substance use disorders.³² Similarly, when a vaccination program was integrated into an outpatient mental health clinic offering various on-site vaccinations, vaccination rates increased by up to 25% over baseline.¹² Such public health approaches of integrating medical care at the site of mental health care, where patients with SMI are most reliably engaged, can be highly cost-effective³³ in terms of reducing disease burden among patients with SMI.

While the psychiatrist may not have the time and resources to directly follow through on all aspects of vaccinations, they can assume leadership and work with the larger team—including therapists and counselors, nurse practitioners, social workers, case managers, care coordinators, or PCPs with whom they regularly collaborate in caring for patients with SMI—to communicate what they have learned about patient hesitancies, share suggestions for future conversations to address these hesitancies, and relay what structural barriers the patient may need assistance to address.

Prioritization of patients with SMI for vaccine eligibility does not directly lead to vaccine uptake. Patients with SMI need extra support from their primary point of health care contact, namely their psychiatrists. Psychiatrists may bring a set of specialized skills uniquely suited to this moment to address vaccine hesitancy and overall lack of vaccine resources and awareness. Freudenreich et al² recently proposed “The ABCs of Successful Vaccinations” framework that psychiatrists can use in their interactions with patients to encourage vaccination by focusing on:

• attitudes towards vaccination
• barriers to vaccination
• completed vaccination series.

Understand attitudes toward vaccination. Decision-making may be an emotional and psychological experience that is informed by thoughts and feelings,³⁴ and psychiatrists are uniquely positioned to tailor messages to individual patients by using motivational interviewing and applying nudging techniques.⁸ Given the large role of the pandemic in everyday life, it would be natural to address vaccine-related concerns in the course of routine rapport-building. Table 2^19,34-38 shows example phrases of COVID-19 vaccine messages that are based on communication strategies that have demonstrated success in health behavior domains (including vaccinations).³⁹

Continue to: First, a strong recommendation...

First, a strong recommendation should be made using the presumptive approach.⁴⁰ If vaccine hesitancy is detected, psychiatrists should next attempt to understand patients’ reasoning with open-ended questions to probe vaccine-related concerns. Motivational interviewing can then be used to target the fence sitters (rather than anti-vaxxers).⁶ Psychiatrists can also communicate with therapists about the need for further follow up on patients’ hesitancies.

When assuring patients of vaccine safety and efficacy, it is helpful to explain the vaccine development process, including FDA approval, extensive clinical trials, monitoring, and the distribution process. Providing clear, transparent, accurate information about the risks and benefits of the vaccines is important, as well as monitoring misinformation and developing convincing counter messages that elicit positive emotions toward the vaccines.⁴¹ Examples of messages to counter common vaccine-related concerns and misinformation are shown in Table 3.^42-44

Know the barriers to vaccination. The role of the psychiatrist is to help patients, particularly those with SMIs, overcome logistical barriers and address hesitancy, which are both essential for vaccine uptake. Psychiatrists can help identify actual barriers (eg, transportation, digital access for information and scheduling) and perceived barriers, improve information access, and help patients obtain self-efficacy to take the actions needed to get vaccinated, particularly by collaborating with and communicating these concerns to other social services (Table 4).⁴¹

Monitor for vaccination series completion. Especially for vaccines that require more than a single dose over time, patients need more reminders, nudges, practical support, and encouragement to complete vaccination. A surprising degree of confusion regarding the timing of protection and benefit from the second COVID-19 injection (for the 2-injection vaccines) was uncovered in a recent survey of >1,000 US adults who had received their vaccinations in February 2021.⁴⁵ Attentive monitoring of vaccination series completion by psychiatrists can thus increase the likelihood that a patient will follow through (Table 4).⁴¹ This can be as simple as asking about completion of the series during appointments, but further aided by communicating to the larger care team (social workers, care managers, care coordinators) when identifying that the patient may need further assistance.

The Figure^2,6,7,19,40 summarizes the steps that psychiatrists can take to help patients get vaccinated by assessing attitudes towards vaccination (vaccine hesitancy), helping to remove barriers to vaccination, and ensuring via patient follow-up that a vaccine series is completed.

Continue to: Active involvement is key

Active involvement is key

The active involvement of psychiatrists in COVID-19 vaccination efforts can protect patients from the virus, reduce health disparities among patients with SMI, and promote herd immunity, helping to end the pandemic. Psychiatry practices can serve as ideal platforms to deliver evidence-based COVID-19 vaccine information and encourage vaccine uptake, particularly for marginalized populations.

Vaccination programs in mental health practices can even be conceptualized as a moral mandate in the spirit of addressing distributive injustice. The population management challenges of individual-level barriers and follow-through could be dramatically reduced—if not nearly eliminated—through policy-level changes that allow vaccinations to be administered in places where patients with SMI are already engaged: that is, “shots in arms” in mental health settings. As noted, some studies have shown that mental health settings can play a key role in other preventive care campaigns, such as the annual influenza and hepatitis vaccinations, and thus the incorporation of preventive care need not be limited to just COVID-19 vaccination efforts.

The COVID-19 pandemic is an opportunity to rethink the role of psychiatrists and psychiatric offices and clinics in preventive health care. The health risks and disparities of patients with SMI require the proactive involvement of psychiatrists at both the level of their individual patients and at the federal and state levels to advocate for policy changes that can benefit these populations. Overall, psychiatrists occupy a special role within the medical establishment that enables them to uniquely advocate for patients with SMI and ensure they are not forgotten during the COVID-19 pandemic.

Bottom Line

Psychiatrists could apply behavior management techniques such as motivational interviewing and nudging to address vaccine hesitancy in their patients and move them to accepting the COVID-19 vaccination. This could be particularly valuable for patients with serious mental illness, who face increased risks from COVID-19 and additional barriers to getting vaccinated.

After more than 600,000 deaths in the United States from the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), several safe and effective vaccines against the virus have become available. Vaccines are the most effective preventive measure against COVID-19 and the most promising way to achieve herd immunity to end the current pandemic. However, obstacles to reaching this goal include vaccine skepticism, structural barriers, or simple inertia to get vaccinated. These challenges provide opportunities for psychiatrists to use their medical knowledge and expertise, applying behavior management techniques such as motivational interviewing and nudging to encourage their patients to get vaccinated. In particular, marginalized patients with serious mental illness (SMI), who are subject to disproportionately high rates of COVID-19 infection and more severe outcomes,¹ have much to gain if psychiatrists become involved in the COVID-19 vaccination campaign.

In this article, we define vaccine hesitancy and highlight what makes psychiatrists ideal vaccine ambassadors, given their unique skill set and longitudinal, trust-based connection with their patients. We expand on the particular vulnerabilities of patients with SMI, including structural barriers to vaccination that lead to health disparities and inequity. Finally, building on “The ABCs of successful vaccinations” framework published in Current Psychiatry March 2021,² we outline how psychiatrists can address vaccine misconceptions, employ effective communication strategies to build vaccine confidence, and help patients overcome structural barriers and get the COVID-19 vaccination. While we are currently focused on ending the COVID-19 pandemic, our broader mission as psychiatrists should be to become ambassadors for other vaccinations as well, such as the annual influenza vaccine.

What is vaccine hesitancy?

The World Health Organization (WHO) defines vaccine hesitancy as a “delay in acceptance or refusal of vaccines despite availability of vaccine services.”^3,4 Vaccine hesitancy occurs on a continuum ranging from uncertainty about accepting a vaccine to absolute refusal.^4,5 It involves a complex decision-making process driven by contextual, individual, and social influences, and vaccine-specific issues.⁴ In the “3C” model developed by the WHO Strategic Advisory Group of Experts (SAGE) Working Group, vaccine hesitancy is influenced by confidence (trust in vaccines, in the health care system, and in policy makers), complacency (lower perceived risk), and convenience (availability, affordability, accessibility, language and health literacy, appeal of vaccination program).⁴

In 2019, the WHO named vaccine hesitancy as one of the top 10 global health threats.³ Hesitancy to receive COVID-19 vaccines may be particularly high because of their rapid development. In addition, the tumultuous political environment that often featured inconsistent messaging about the virus, its dangers, and its transmission since the early days of the pandemic created widespread public confusion and doubt as scientific understandings evolved. “Anti-vaxxer” movements that completely rejected vaccine efficacy disseminated misinformation online. Followers of these movements may have such extreme overvalued ideas that any effort to persuade them otherwise with scientific evidence will accomplish very little.^6,7 Therefore, focusing on individuals who are “sitting on the fence” about getting vaccinated can be more productive because they represent a much larger group than those who adamantly refuse vaccines, and they may be more amenable to changing beliefs and behaviors.⁸

The US Census Bureau’s Household Pulse Survey asked, “How likely are you to accept the vaccine?”⁹ As of late June 2021, 11.4% of US adults reported they would “definitely not get a vaccine” or “probably not get a vaccine,” and that number increases to 16.9% when including those who are “unsure,” although there is wide geographical variability.¹⁰

A recent study in Denmark showed that willingness to receive the COVID-19 vaccine was slightly lower among patients with mental illness (84.8%) compared with the general population (89.5%).¹¹ Given the small difference, vaccine hesitancy was not considered to be a major barrier for vaccination among patients with mental illness in Denmark. This is similar to the findings of a pre-pandemic study at a community mental health clinic in the United States involving other vaccinations, which suggested that 84% of patients with SMI perceived vaccinations as safe, effective, and important.¹² In this clinic, identified barriers to vaccinations in general among patients with SMI included lack of awareness and knowledge (42.2%), accessibility (16.3%), personal cost (13.3%), fears about immunization (10.4%), and lack of recommendations by primary care providers (PCPs) (1.5%).¹²

It is critical to distinguish attitude-driven vaccine hesitancy from a lack of education and opportunity to receive a vaccine. Particularly disadvantaged communities may be mislabeled as “vaccine hesitant” when in fact they may not have the ability to be as proactive as other population groups (eg, difficulty scheduling appointments over the Internet).

What makes psychiatrists ideal vaccine ambassadors?

There are several reasons psychiatrists can be well-positioned to contribute to the success of vaccination campaigns (Table 1). These include their frequent contact with patients and their care teams, the high trust those patients have in them, and their medical expertise and skills in applied behavioral and social science techniques, including motivational interviewing and nudging. Vaccination efforts and outreach are more effective when led by the clinician with whom the patient has the most contact because resolving vaccine hesitancy is not a one-time discussion but requires ongoing communication, persistence, and consistency.¹³ Patients may contact their psychiatrists more frequently than their other clinicians, including PCPs. For this reason, psychiatrists can serve as the gateway to health care, particularly for patients with SMI.¹⁴ In addition, interruptions in nonemergency services caused by the COVID-19 pandemic may affect vaccine delivery because patients may have been unable to see their PCPs regularly during the pandemic.¹⁵

Psychiatrists’ medical expertise and their ability to develop rapport with their patients promote trust-building. Receiving credible information from a trusted source such as a patient’s psychiatrist can be impactful. A recent poll suggested that individual health care clinicians have been consistently identified as the most trusted sources for vaccine information, including for the COVID-19 vaccines.¹⁶ There is also higher trust when there is greater continuity of care both in terms of length of time the patient has known the clinician and the number of consultations,¹⁷ an inherent part of psychiatric practice. In addition, research has shown that patients trust their psychiatrists as much as they trust their general practitioners.¹⁸

Psychiatrists are experts in behavior change, promoting healthy behaviors through motivational interviewing and nudging. They also have experience with managing patients who hold overvalued ideas as well as dealing with uncertainty, given their scientific and medical training.

Motivational interviewing is a patient-centered, collaborative approach widely used by psychiatrists to treat unhealthy behaviors such as substance use. Clinicians elicit and strengthen the patient’s desire and motivation for change while respecting their autonomy. Instead of presenting persuasive facts, the clinician creates a welcoming, nonthreatening, safe environment by engaging patients in open dialogue, reflecting back the patients’ concerns with empathy, helping them realize contradictions in behavior, and supporting self-sufficiency.¹⁹ In a nonpsychiatric setting, studies have shown the effectiveness of motivational interviewing in increasing uptake of human papillomavirus vaccines and of pediatric vaccines.²⁰

Nudging, which comes from behavioral economics and psychology, underscores the importance of structuring a choice architecture in changing the way people make their everyday decisions.²¹ Nudging still gives people a choice and respects autonomy, but it leads patients to more efficient and productive decision-making. Many nudges are based around giving good “default options” because people often do not make efforts to deviate from default options. In addition, social nudges are powerful, giving people a social reference point and normalizing certain behaviors.²¹ Psychiatrists have become skilled in nudging from working with patients with varying levels of insight and cognitive capabilities. That is, they give simple choices, prompts, and frequent feedback to reinforce “good” decisions and to discourage “bad” decisions.

While the implementation of mass vaccinations is a public health task, individual clinicians are critical for the success of any vaccination campaign. Psychiatrists may be well positioned to help increase vaccine uptake among psychiatric patients. They see their patients more frequently than primary care physicians do, which allows for patient engagement over time regarding vaccinations. Also, as physicians, psychiatrists are a trusted source of medical information, and they are well-versed in using the tools of nudging and motivational interviewing to manage ambivalence about receiving a vaccine (vaccine hesitancy).¹

The “ABCs of successful vaccinations” (Figure) provide a framework that psychiatrists can use when speaking with their patients about vaccinations. The ABCs assess psychological factors that hinder acceptance of vaccination (A = Attitudes toward vaccination), practical challenges in vaccine access for patients who are willing to get vaccinated (B = Barriers to vaccination), and the actual outcome of “shot in the arm” (C = Completed vaccination series). The Figure provides examples of each area of focus.

How to talk to patients about vaccines

“Attitudes toward vaccination” is an area in which psychiatrists can potentially move patients from hesitancy to vaccine confidence and acceptance. First, express confidence in the vaccine (ie, make a clear statement: “You are an excellent candidate for this vaccine.”). Then, begin a discussion using presumptive language: “You must be ready to receive the vaccine.” In individuals who hesitate, elicit their concern: “What would make vaccination more acceptable?” In those who agree in principle about the benefits of vaccinations, ask about any impediments: “What would get in the way of getting vaccinated?” While some patients may require more information about the vaccine, others may need more time or mostly concrete help, such as assistance with scheduling a vaccine appointment. Do not to forget to follow up to see if a planned and complete vaccination series has taken place. The CDC offers an excellent online toolkit to help clinicians discuss vaccinations with their patients.²

Psychiatric patients, particularly those from disadvantaged and marginalized populations, have much to gain if psychiatrists are involved in preventive health care, including the coronavirus vaccination drive or the annual flu vaccination campaign.

Also, as physicians, psychiatrists are a trusted source of medical information, and they are well-versed in using the tools of nudging and motivational interviewing to manage ambivalence about receiving a vaccine (vaccine hesitancy).¹

The “ABCs of successful vaccinations” (Figure) provide a framework that psychiatrists can use when speaking with their patients about vaccinations. The ABCs assess psychological factors that hinder acceptance of vaccination (A = Attitudes toward vaccination), practical challenges in vaccine access for patients who are willing to get vaccinated (B = Barriers to vaccination), and the actual outcome of “shot in the arm” (C = Completed vaccination series). The Figure provides examples of each area of focus.

How to talk to patients about vaccines

“Attitudes toward vaccination” is an area in which psychiatrists can potentially move patients from hesitancy to vaccine confidence and acceptance. First, express confidence in the vaccine (ie, make a clear statement: “You are an excellent candidate for this vaccine.”). Then, begin a discussion using presumptive language: “You must be ready to receive the vaccine.” In individuals who hesitate, elicit their concern: “What would make vaccination more acceptable?” In those who agree in principle about the benefits of vaccinations, ask about any impediments: “What would get in the way of getting vaccinated?” While some patients may require more information about the vaccine, others may need more time or mostly concrete help, such as assistance with scheduling a vaccine appointment. Do not to forget to follow up to see if a planned and complete vaccination series has taken place. The CDC offers an excellent online toolkit to help clinicians discuss vaccinations with their patients.²

Psychiatric patients, particularly those from disadvantaged and marginalized populations, have much to gain if psychiatrists are involved in preventive health care, including the coronavirus vaccination drive or the annual flu vaccination campaign.
