Chronic pain, one of the most common reasons adults seek medical care. Chronic pain contributes to an estimated $560 billion each year in direct medical costs, lost productivity, and disability programs.
High Impact Chronic Pain (HICP), is a new concept that describes those with pain lasting three months or longer and accompanied by at least one major activity restriction.
The concept of HICP was first proposed by the National Pain Strategy to better identify those with significant levels of life interference.
The National Pain strategy was core recommendation of the 2011 Institute of Medicine Report: Relieving Pain in America. Recommendation 2-2 said that “The Secretary of the Department of Health and Human Services should develop a comprehensive, population health-level strategy for pain prevention, treatment, management, education, reimbursement, and research that includes specific goals, actions, time frames, and resources.”
The National Pain Strategy, is the first national effort to transform how the population burden of pain is perceived, assessed, and treated, recognizes the need for better data to inform action and calls for estimates of chronic pain and high-impact chronic pain in the general population.
Together, the HICP population constitutes some 4.8 percent of the U.S. adult population. About 83 percent of people with HICP were unable to work for a living, and one-third had difficulty with self-care activities such as washing themselves and getting dressed. Almost 11 million U.S. adults have High Impact Chronic Pain.
Activity limitations were more common in the chronic pain population than in groups with other chronic health conditions, such as stroke, kidney failure, cancer, diabetes, or heart disease.
“By differentiating those with HICP, a condition that is associated with higher levels of anxiety, depression, fatigue, and cognitive difficulty, we hope to improve clinical research and practice,” said M. Catherine Bushnell, Ph.D., scientific director in the NCCIH Division of Intramural Research and another author of the study.
“It is crucial that we fully understand how people’s lives are affected by chronic pain. It will help improve care for individuals living with chronic pain and strategically guide our research programs that aim to reduce the burden of pain at the population level,” said Linda Porter, Ph.D., director of the Office of Pain Policy at NINDS.
