This paper examines primary care physicians' (PCP) roles in helping the nation prepare for, respond to, and recover from the psychologic consequences of chemical, biologic, radiologic, or nuclear (CBRN) terrorism. First, we discuss the psychologic consequences of a CBRN attack and PCPs' roles in responding to these consequences. Second, we analyze these roles in light of the known barriers to delivering high-quality, primary care–based, mental health care. Third, we offer recommendations for mitigating these barriers and preparing PCPs to respond to the psychosocial consequences of a CBRN weapon. Importantly, our recommendations provide dual-use benefits to PCPs faced with the daily concerns of primary care mental health, including improved linkages and electronic connectivity with mental health, information technology, and decision support for providers, and needed education and research.

Since the September 11, 2001, and subsequent anthrax attacks, substantial federal funds have been devoted to improving the health care system's capacity to detect and respond to a chemical, biologic, radiologic, or nuclear (CBRN) weapon attack. These events highlighted primary care physicians' (PCPs) contributions to addressing the psychologic consequences of terrorism.1–5 After the attacks, PCPs reported a willingness to deliver CBRN-related mental health care, especially if education, links with mental health care, and improved reimbursement were available.5,6
PCPs should ensure that their interests are represented in the mental health care planning for a CBRN event. Mental health experts and disaster planners recognize that primary care, already the major component of the “de facto mental health care system,”7 will have to respond to the emotional and behavioral consequences of the event.5,8,9 Estimates of psychologic to physical casualties range from 5 to 1 to 50 to 1 and will likely be widespread and enduring.9–11 Primary care may be a central location for triaging patients into primary care–based mental health interventions.12 Appropriate preparation and planning by administrators, PCPs (and PCPs' families) will likely reduce their work burden13 and the risk of stress, trauma, and burnout.14,15 Importantly, such planning for primary mental health care after a CBRN event serves a “dual-use” function as an opportunity for improving the quality of mental health care for routine mental health problems that occur in daily clinical care.6 A similar dual-use revamping of the public health system is occurring with federal funds for bioterrorism preparedness.16
The quality of primary mental health care, already hampered by barriers at the conceptual, patient, provider, and system levels,17 will face new additions to these barriers after an attack. After discussing the psychologic consequences of a CBRN attack and PCPs' anticipated roles in response, we examine what these barriers imply for primary mental health care. Next, we offer recommendations for mitigating these barriers and preparing PCPs to respond to the psychosocial consequences of a CBRN weapon.
PSYCHOLOGIC CONSEQUENCES AND PCPS' ROLESA CBRN attack may lead to or exacerbate depression,18 anxiety disorders,19 posttraumatic stress disorder (PTSD),20 somatization disorders, and substance use21 even among persons distant from the attack.2,22–28 The triaging of distressed patients29 may allow PCPs to counsel patients to help them manage their anxieties about exposure, infection, contagion, illness severity, and access to therapeutic and prophylactic measures. Grief counseling, already variably performed by PCPs,30 may also be needed for individuals who have lost friends or loved ones.31
Nonspecific symptoms, coupled with the absence of rapid, definitive diagnostic testing, and uncertainty about how to assess exposure and the optimal prophylaxis regimen (as occurred in the 2001 anthrax event), may exacerbate anxieties and lead to noncompliance with public health recommendations.32 Common physical complaints may stimulate demands for medical intervention in the absence of evidence of exposure. For example, over 30,000 individuals were offered prophylactic antibiotics during the relatively small 2001 anthrax attack33 in which only 22 people were infected,34 and many more individuals, some far from the attack, sought antibiotics outside of official channels.35 Unexposed patients may present with somatic symptoms mimicking exposure symptoms.36 For example, when a radioactive substance in Brazil contaminated 250 persons in 1987, 5,000 of the first 60,000 persons screened had symptoms of acute radiation sickness (e.g., vomiting, diarrhea, and neck/facial rash), but none were contaminated. Disaster Somatization Reaction (DSR), a disaster psychiatry term for unexposed individuals who interpret their anxiety symptoms as evidence of exposure or infection or exhibit symptoms similar to the disease, replaces the stigmatized terms “hysteria” and “psychogenic illness,”37 which have little triage value.
Some agents can linger in the environment for weeks to years (e.g., anthrax38 and radiologic isotopes), sustaining exposure risk and prolonging stress. Unexplained, persistent neuropsychologic problems can be an effect of CBRN agents.21,39 One year after the anthrax attacks, survivors reported memory difficulties, poor concentration,40,41 and psychological distress.42 PCPs with patients experiencing “multiple unexplained physical symptoms” (MUPS)12,43 may have difficulty in determining whether such symptoms are because of a medical condition or are psychological in origin.40
Managing PCPs' own emotional and behavioral responses will also be important. In the aftermath of the Toronto SARS epidemic where 40% of the 20,000 quarantined persons were health care workers, high rates of PTSD and depression symptoms among surviving health care workers were described44,45 and the value of psychosocial support for quarantined workers was demonstrated.14,15 In a CBRN event, demands for unnecessary testing and prescriptions may further stress already strained PCPs whose fears and angers may be exacerbated by those of their patients.46 These providers will be at risk for burnout, stress disorders, anxiety, and depression.47,48
BARRIERS TO PCP DELIVERY OF MENTAL HEALTH CARE IN A CBRN EVENTExisting barriers to delivering high-quality primary mental health care are relevant to PCPs' abilities to deliver psychosocial care after a CBRN event.
Conceptual BarriersMental health providers linked to different systems from PCPs (e.g., social workers in social service systems) may have scant understanding of primary care. Conversely, PCPs view the DSM-IV-R as too complex and specialty focused.49,50 Existing treatment guidelines for primary care focus on major disorders and little guidance is provided about sub-threshold forms of PTSD,51,52 panic,53 somatization,54,55 and substance abuse,56 although all may affect functioning. The burgeoning field of disaster mental health57 and its evolving terminology may add an additional communication barrier in the event of a CBRN event.
Provider- and Patient-Level BarriersMost Americans will likely turn first to their physicians for information about a bioterrorist event,58 but studies performed before September 11 reported that physicians are reluctant to inquire about personal traumas.59–61 Risk communication with patients may reduce their emotional distress62 but this is not a skill mastered by all physicians,63 as demonstrated during the anthrax attacks.32 In addition, labeling individuals presenting with somatic symptoms without an apparent physical etiology as “worried well” will create an obstacle between patient and provider.13,36 Somatic presentations of emotional distress can act as a barrier to its detection and response. Nonspecific symptoms coupled with providers' reluctance to repeatedly test for exposure or infection may exacerbate patients' anxieties.
System BarriersMental health providers are isolated from PCPs in the health care system and payment structures provide disincentives to PCPs treating mental health problems.64 These barriers may be exacerbated after a CBRN attack because of the confusing array of organizations that will be involved and the lack of clarity about payment mechanisms.29 Most primary care practices have little experience with the Substance Abuse and Mental Health Services Administration (SAMHSA), the lead federal agency for disaster mental health response. Public mental health systems charged with delivering disaster mental health care usually do not incorporate PCPs into their postdisaster treatment policies, trainings, and reimbursements.65 Differentiating long-term organic mental disorders from psychologic distress and formulating an appropriate treatment plan will require guidance in distinguishing and referring patients and linkage between primary care and disaster response agencies.66 Existing collaborative care models do not incorporate the public health and disaster experts so additional linkages are needed if patients are to be triaged into proposed interventions12 for reducing development of chronic medically unexplained syndromes (e.g., Gulf War syndrome).9
RECOMMENDATIONSPrimary care physicians can play important roles in policy, education, and research that will contribute to overcoming these barriers and preparing them to respond to the psychosocial consequences of a CBRN weapon (see Table 1).

SAMSHA could ensure that PCPs are prepared to address CBRN-related concerns in patients, including being able to provide relevant recommendations, education, testing, and referrals.9 SGIM should suggest that the Federal Disaster Response Plan, which guides the coordinated delivery of federal assistance and resources in the event of a major disaster, should address the complex and ambiguous long-term mental health disorders that do not fit traditional diagnostic categories but are likely to be treated by PCPs.66 Such activities would likely benefit the public mental health system, as enhancing PCP capacity to address these issues will reduce financial and workforce strain among mental health providers.65–68 Administrators and primary care leaders of managed health care organizations, health plans, and other health organizations should begin by meeting with state and local medical societies and bioterrorism coordinators to learn about how existing disaster mental health plans incorporate primary care services, and to acquaint themselves with model linkages that they can implement after a CBRN event. (The job of bioterrorism coordinators, located in public health agencies and often funded by CDC and DHHS grants, includes working with the private sector.)69 For example, the Department of Defense implemented a novel program after September 11 in which PCPs were assigned to a trained care manager to help treat terrorism-related problems.70 A proposed stepped system of evidence-based rehabilitative care for military personnel that links primary care, mental health, and public health and disaster experts in the prevention and treatment of disaster-related somatic symptoms could be adapted for civilian populations.71,72 Health plans can develop 2-way communication systems between primary care and behavioral health call centers and case managers,16 supported by funding from DHHS's Bioterrorism and Cooperative Agreement Program, which is intended for improving communications.73 Information technologies (e.g., telemedicine, electronic linkages) planned for front-line clinicians should include links to mental health services and decision support programs. Also, PCPs can have input into disaster response plans by participating in local municipal and hospital disaster management exercises. Lastly, PCPs working in hospital-based practices and managed care organizations should ensure that they are represented in their hospital's or organization's incident command structure, which is responsible for managing and coordinating the response to a disaster.
Disaster planning should include training PCPs about the emotional and behavioral responses: Standard educational curriculums can do more to emphasize training in grief and bereavement and the science-based approach to risk communication. They should include simple interventions such as psychologic first aid, a set of skills believed to limit distress, and negative health behaviors.9,10 Training should also address PCP's own responses to a CBRN attack by developing family and practice disaster plans,29 including prevention of PCPs' adverse psychologic reactions.46,74 Training should address the psychologic impacts of isolation and quarantine and formal skills in risk communication that will help them access and use risk information when it is disseminated. PCPs should learn about DSR and MUPS and establish guidelines of care to both inform that education and guide the management and referral of these patients. Training modules and curriculum can build on existing ones (e.g., http://www.med.nyu.edu/chip), be prepared and tested in advance, and disseminated as “just-in-time” packages with information on referrals.
PCPs should research critical knowledge gaps: PCPs need to develop and study models of mental health linkages between primary care and the different service sectors that will operate in a CBRN event. More information is needed about PCPs' roles in addressing sub-threshold mental health disorders and somatization symptoms resulting from a disaster. Research into the long-term psychologic consequences of the anthrax attacks and SARS epidemic is required to ameliorate any potential future public health problems.36,72 Finally, additional research is needed on what aspects of PCPs' knowledge and skills in addressing traumatic issues occurring in everyday practice (e.g., interpersonal violence) are most relevant for addressing psychologic issues in the aftermath of a CBRN event.
CBRN response planning could help spur improvements in the daily management of routine mental health problems in primary care settings, similar to the way federal bioterrorism funds are improving the public health infrastructure. Efforts to address the primary care–based treatment of these mental health consequences6 should be sustained and increased as recommended.
