Violence intervention programs 'could save hospitals millions'

While violence intervention programs have demonstrated that they can be an effective way of preventing violent injury, little has been known about their financial implications. 

A new research now suggests that these interventions could save various sectors millions of dollars.

Hospital-based violence intervention programs can include behavioral counseling, case management and other services.

Researchers from Drexel University have analyzed the cost-benefit ratio of hospital-based violence intervention programs (HVIPs) and report that - as well as benefiting victims' lives - HVIPs can make costs savings of up to $4 million over a 5-year period in the health care and criminal justice sectors.

The researchers said that, this is the first systematic economic evaluation of a hospital-based violence intervention program, and it's done in a way that can be replicated as new evidence emerges about the programs' impacts across different sectors.

As a major cause of disability, premature mortality and other health problems worldwide, HVIPs have a crucial role to play in helping victims from experiencing further suffering.

The provision of case-management and counseling from combinations of medical professionals and social workers has been associated with not only reducing rates of aggressive behavior and violent re-injury but also improving education, employment and health care utilization for service users.

Many HVIPs still require a sustainable source of funding

Intervention typically begins in the period immediately after a violent injury has been sustained. Not only is this a critical moment in terms of physical health, but it can also be a time when victims may start thinking about retaliation or making changes in their lives.

In 2009, around six programs were in operation and, as word of their success has spread, more and more HVIPs have been initiated.

Calculating the potential financial benefits of HVIPs is crucial, as for many of these programs a stable and sustainable source of funding does not exist. Instead, many rely on a variety of different financial sources such as insurance billing, institutional funding, local government funding and private grants.

For the study, published in the American Journal of Preventive Medicine, the researchers conducted a cost-benefit analysis simulation in order to estimate what savings an HVIP could make over 5 years in a hypothetical population of 180 violently injured patients. Of these, 90 would receive HVIP intervention and 90 would not.

Costs, rates of violent re-injury and violent perpetration incidents that a population would be estimated to experience were calculated by the authors using data from 2012.

The authors made a comparison between the estimated costs of outcomes that would most likely be experienced by the 90 hypothetical patients receiving HVIP intervention - including $350,000 per year costs of the HVIP itself - and the costs of outcomes predicted for 90 patients not receiving any HVIP intervention.

The net benefit of the interventions

A total of four different simulation models were constructed by the researchers to estimate net savings and cost-benefit ratios, and three different estimates of HVIP effect size were used.

Costs that were factored into the simulations included health care costs for re-injury, costs to the criminal justice system if the victims then became perpetrators and societal costs for potential loss of productivity.

Each simulation calculated that HVIPs produced cost savings over the course of 5 years. The simulation model that only included future health costs for the 90 individuals and their potential re-injury produced savings of $82,765. The simulation model including all costs incurred demonstrated savings of over $4 million.

The researchers acknowledge that estimated lost productivity costs may have been slightly high due to an assumption in their data that all individuals in the simulation were employed. However, the research team believes that there are also many social benefits to HVIPs that cannot be financially quantifiable:

"Even if the intervention cost a little more than it saved in dollars and cents to the health care system, there would still be a net benefit in terms of the violence it prevented."

The authors of this research believe that the findings of their study could be useful in informing public policy decisions. By demonstrating that HVIPs can be financially beneficial, the study suggests that an investment in HVIPs is one that pays off for everyone concerned.
