Violence as a health concern

Recent advances in neuroscience, behavioural science, and epidemiology demonstrate that violence behaves like other contagious epidemics, yet violence is not primarily managed by the health sector

Violence as a health concern

Violence is best understood as an epidemic health problem, and it can be effectively prevented and treated using health methods to stop events and outbreaks and to reduce its spread. This health framing is important because it recognizes that violence is a threat to the health of populations, that exposure to violence causes serious health problems, and that violent behavior is contagious and can be treated as a contagious process. Relatively standard and highly effective health approaches to changing behaviors and norms are increasingly being applied to the problem of violence and are showing strong evidence of impact among individuals and communities. We need to mobilize our nation’s health care and public health systems and methods to work with communities and other sectors to stop this epidemic.
Because of its pervasiveness and far-reaching effects, violence is one of the most devastating national and global challenges we face. Violence not only causes injury and death; it also erodes the physical, psychological, social, and economic health and development of nearly everyone in affected communities, reducing life expectancy, inflicting trauma, limiting opportunity and achievement, and further entrenching inequities.
Recent advances in neuroscience, behavioral science, and epidemiology demonstrate that violence behaves like other contagious epidemics, yet violence is not primarily managed by the health sector, and health professionals are not the principal spokespersons or policy advocates on the issue. While health and public health methods for stopping violence exist and have been proven effective, they are underutilized and under-resourced.

Health professionals have ethical responsibilities to fully understand violence; to convey accurate information to patients, families, and the community; to provide the best care and follow-up to ensure recovery from violence, and to help prevent violence. We health professionals also have an ethical obligation to educate the public and policymakers about the new scientific understanding of violence as a contagious process that has emerged. It is our job to share this new understanding to shift the world’s thinking toward scientifically grounded solutions for violence prevention. This write-up outlines what is known about violence as a health issue and contagious process, effective programs for reducing violence, and practitioners’ obligations to reverse this epidemic by acting on this new knowledge.

People at heightened risk for violence have acquired this susceptibility in the same way that people acquire other contagious diseases—through exposure. The particular contagion of violence is initiated by victimization or visual exposure and mediated by the brain, just as the lungs mediate replication of tuberculosis or the intestines cholera. The brain processes violence exposure into scripts, or copied behaviors, and unconscious social expectations. This processing can also lead to several situationally adaptive responses including aggression, impulsivity, depression, stress, exaggerated startle responses, and changes in neurochemistry. The result in each case is the production of more of what there was an exposure to, i.e., transmission to subsequent person(s) or groups. Health and Public Health Methods to Prevent Violence:  New methods are now available for stopping the spread of violence that is tailored to its disease-like characteristics. The public health sector has a strong record of effectively preventing disease—including stopping the epidemic disease—changing norms and behaviors, and reaching high-risk populations. The epidemic control approach to reducing violence will be highly recognizable to those who have worked in infectious and epidemic control. Community-based health workers are selected, trained, supervised, and supported under the guidance of the health sector. Health workers map out areas of highest transmission and symptom manifestation, reach out to and intervene with those displaying clinical signs to reduce further transmission using methods tailored to the infectious agent at play, detect close contacts and others with emergent symptoms or at highest risk of future contraction, and render all those at highest risk less symptomatic and likely to transmit. Through these methods, health workers reduce the spread of the contagion and reverse the epidemic process. As with other contagious health problems such as AIDS, new protective behaviors and norms are then promoted and supported at the community level.

The Cure Violence approach employs violence interrupters, outreach workers, and hospital responders to prevent violent events and retaliations, reduce risk among those most likely to become violent and shift norms to discourage the use of violence. Violence interrupters work to detect and interrupt conflicts to prevent them from escalating into potentially fatal violence. Outreach workers identify those at the highest risk and work to decrease their likelihood of violence by addressing their risk factors. Community-based hospital responders may provide immediate crisis intervention to victims of violence at hospital trauma centers, work to prevent retaliation or subsequent re-injury, and address psychological trauma that the victims experience as a result of their violent victimization. Each of these workers may be hired from the communities being served based upon their credibility with those at highest risk and is extensively trained in techniques needed for the work, including methods of conflict detection and mediation, behavior change, norm change, and epidemic control strategies. This approach to violence reduction is complementary to and augments the vital public safety role of law enforcement.

Ethical Implications of Understanding Violence as a Health Issue: Given evidence of the contagious nature of violence and the effectiveness of violence prevention programs using the epidemic control approach, our understanding of our role as health practitioners in relation to the problem of violence must now evolve. First, as part of our ethical obligations, we must more fully understand the essential components for providing competent care and follow up to victims of violence, including those with physical injuries, those traumatized by exposure, and communities as a whole. In some instances, and particularly in the case of community violence, victims of violence are at greater risk to be involved in future violence. Thus, in addition to acute care, we must provide intervention aimed at reducing the risk of patients’ injury, retaliation, or engagement in subsequent violence. Persons traumatized from exposure to violence must be identified and treated based upon the severity of their trauma. There is a role for all health practitioners who come into contact with people exposed to violence in providing screening, trauma-informed care and follow up. Finally,  health professionals have credibility as spokespersons and thus need to step into this role more proactively and with greater visibility. We have the ability to provide a health framework on violence and its transmission, as we did for Dengue and to encourage more effective policies and practices that will lead to better outcomes. During most epidemics, fear is prevalent, but accurate information provided by health professionals helps ensure the best responses to and outcomes for those affected and the general public.

Conclusion: Violence is best understood as an epidemic health problem. It is transmitted through exposure, which is mediated by the brain and social processes and can be effectively prevented and treated using health methods. This scientifically grounded understanding of violence holds the potential for a fundamental shift in how violence and persons who show symptoms of it are treated. Recognition and treatment of violence as a health crisis is long overdue. To date, the health sector and health professionals have been highly underutilized for the prevention, treatment, and control of violence. Health practitioners—from pediatricians to emergency medical personnel, from nurses to public health professionals, from mental health professionals to trauma specialists, and especially community health workers—need to step up and use new detection and intervention methods to treat violence and to advocate for competent care for all, both through existing health care institutions and a more robust community health system.

These new methods should be widely used and supported within the health sector and in the community through training, curricula, and standards of practice and further advanced through a reprioritization of resources to support health-based approaches to reducing and preventing violence. Now is the time for our nation’s health care and public health systems to work with communities and other sectors to stop this epidemic. Each of us has a role in making this happen.
