RSI STATISTICS

According to the U.S. Department of Labor, Occupational Safety and Health Administration (OSHA), repetitive strain injuries are the nation's most common and costly occupational health problem, affecting hundreds of thousands of American workers, and costing more than $20 billion a year in workers compensation.

According to the U.S. Bureau of Labor Statistics, nearly two-thirds of all occupational illnesses reported, were caused by exposure to repeated trauma to workers upper body ( the wrist, elbow or shoulder ). One common example of such an injury is carpal tunnel syndrome.

The only national routine source of information on occupational injuries and illnesses experienced by U.S. workers is the Annual Survey of Occupational Injuries and Illnesses conducted by the Bureau of Labor Statistics (BLS). The survey is a random sample of about 250,000 private sector establishments, but excludes the self-employed, farms with fewer than 11 employees, private households, and ALL GOVERNMENT AGENCIES. -Statement of Lina Rosenstck, M.D., M.P.H. Director of National Institute For Occupational Safety And Health before the Subcommittee on Workforce Protections Committee on Education and the Workforce-U.S. House of Representatives 5/21/97.

Musculoskeletal disorders, including carpal tunnel syndrome, are among the most prevalent medical conditions in the U.S., affecting 7% of the population. They account for 14% of physician visits and 19% of hospital stays. 62% of the persons with musculoskeletal disorders report some degree of limitation on activity, compared with 14% of the population at large, according to the National Institute for Occupational Safety and Health.

849,000 new cases of carpal tunnel syndrome occurred in 1994.-National Center for Health Statistics.

Approximately 260,000 carpal tunnel release operations are performed each year, with 47% of the cases considered to be work related.-National Center for Health Statistics.

Carpal tunnel syndrome results in the highest number of days lost among all work related injuries. Almost half of the carpal tunnel cases result in 31 days or more of work loss.-National Center for Health Statistics.

A report by NIOSH revealed that more than 50% of all food cashiers, (jobs predominantly held by women), suffered some degree of carpal tunnel syndrome and other forms of repetitive strain injuries as a result of the physical demands of scanning products at high speed.

Each worker compensation claim for repetitive stress injuries can cost up to $20,000 - $100,000. Consumer Watch Report, PC World, May 1993.

According to the National Council on Compensation Insurance, Inc., the average total cost per workers' compensation claim for CTS is $12,370.00. 1111 Jennifer Kish and Valdy Dobrila, Carpal Tunnel Syndrome In Workers Compensation: Frequency, Costs andClaim Characteristics , NCCI Research Brief Vol. 3, Issue 3, June 1996, at *4. This total cost includes lostwages and medical costs.

: Presently, the costs to businesses that employ workers at high risk to develop Carpal Tunnel Syndrome and other Repetitive Stress Injuries is staggering. It is estimated that RSI "costs employers over $80 billion yearly." According to the National Council of Compensation Insurance, the average compensation of a CTS victim is $33,000.00.

Along with increasing numbers of CTS, costs are escalating too, quadrupling since 1987. The average cost of a single case of Carpal Tunnel Syndrome, for example, rose to $30,000 in 1988 per the Bureau of National Affairs.

The U.S. Department of Labor has concluded that Carpal Tunnel Syndrome is the "chief occupational hazard of the 90's"-disabling workers in epidemic proportions.

Currently, Carpal Tunnel Syndrome affects over 8-million Americans.

Carpal Tunnel Syndrome is the #1 reported medical problem, accounting for about 50% of all work-related injuries

Presently, 25% of all computer operators have Carpal Tunnel Syndrome, with estimates that by the year 2000, 50% of the entire workforce may be affected.

Only 23% of all Carpal Tunnel Syndrome patients were able to return to their previous professions following surgery.

Up to 36% of all Carpal Tunnel Syndrome patients require unlimited medical trearment.

Women are twice as likely to develop Carpal Tunnel Syndrome as opposed to their male counterparts.

While women account for about 45% of all workers, they experience nearly 2/3's of all work-related Repetitive Strain Injuries.

Surgery for Carpal Tunnel Syndrome is the second most common type of surgery, with well over 230,000 procedures performed annually.

The National Institute of Occupational Safety and Health (NIOSHA) reports that by the year 2000 one half of all office workers may suffer symptoms of CTDs. If the incidences should rise as NIOSHA predicts- 50% of all office workers will be averaging a CTD cost of $2,000 each.

Injuries resulting from repeated motion (repetitive / cumulative trauma disorders -- CTDs) are growing. According to recent annual statistics from the U.S. Survey of Occupational Injuries and Illnesses , over 302,000 CTDs account for nearly two-thirds all of workplace-related illnesses.

Ergonomic disorders are the fastest growing category of work-related illness. According to the most recent statistics from the U.S. Bureau of Labor Statistics , they account for 56 percent of illnesses reported to the Occupational Safety and Health Administration.

United States, employers spend more than $7.4 billion in workers compensation costs, and untold billions on medical treatment, litigation costs, hidden costs and lost productivity. U.S. Bureau of Labor and Statistics

More than eight million people are affected by carpal tunnel syndrome each year. Surgery for carpal tunnel syndrome is the second most common type of musculoskeletal surgery, (back surgery is #1) with well over 230,000 procedures performed annually.

ONLY 23% of all carpal tunnel syndrome patients returned to their previous professions following surgery,according to the Bureau of Labor & Statistics and the National Institute for Occupational Safety & Health (1997-2000 Statistics).

Carpal tunnel surgery has about a 57% failure rate following patients from 1-day to 6-years. At least one of the following symptoms re-occurred during this time: Pain, Numbness, Tingling sensations. Source: Nancollas, et al, 1995. J. Hand Surgery.

Musculoskeletal disorders are the country's most costly category of workplace injuries and illnesses. In addition to spending $20 billion annually on workers' compensation costs due to RSIs, the U.S. spends another $100 billion on lost productivity, employee turnover, and other indirect expenses; The Agency for Health Care Policy and Research.

According to a recent survey conducted by CTD News (reported June '98 issue, page 7), a common office cumulative trauma disorder -carpal tunnel syndrome or CTS- averaged $1,918 per case in 1997. (This does not include surgery or rehabilitation because the national average is more than $12,000 per hand.)

The U.S. Department of Labor has concluded that Carpal Tunnel Syndrome is the "chief occupational hazard of the 90's"-disabling workers in epidemic proportions.

Each year thousands of people are diagnosed with some kind of an illness directly related to poorly designed work stations. In the U.S., Repetitive Strain Injury (RSI, for short) has become the number one work-related health problem, according to OSHA statistics.

Other industries, however, have higher total numbers of CTS-related events that cause lost-work days. The following is a list of occupations published by the Bureau of Labor Statistics in 2002 that rates workers with highest to lowest numbers of such events: SOURCE: Bureau of Labor Statistics, U.S. Department of Labor, April 2002 .  Assemblers .  Cashiers .  Secretaries .  General office clerks .  Laborers, non-construction .  Bookkeeping, accounting, and auditing clerks .  Welders and cutters .  Data-entry employees .  Textile sewing machine operators .  Order clerks .  Supervisors and proprietors, sales occupations .  Machine operators (unspecified) .  Truck drivers .  Investigators and adjusters, (not insurance) .  Insurance adjusters, examiners, and investigators .  Electrical and electronic equipment assemblers .  Packaging and filling machine operators .  Janitors and cleaners .  Bank tellers .  Production inspectors, checkers, and examiners

In the industrialized world, the incidence of musculoskeletal injury (MSI) has reached epidemic proportions. In the United States, these disorders affect one out of every four people (American Academy of Orthopedic Surgeons, 2000).

According to the National Institute for Occupational Safety and Health (NIOSH), MSIs account for one-third of all job-related injuries.

A national health survey completed by Statistics Canada in 1998 found one out of fifteen Canadians living with a potentially disabling MSI. In Ontario, approximately one half of workers compensation claims are for muscular strains and strains (Workplace Safety and Insurance Board, Statistical Supplement to the Annual Report, 2000).

MUSCULOSKELTAL INJURIES (MSI's):

Work related musculo-skeletal injuries (MSIs) affecting the upper body and limbs are now recognized as one of the leading causes of worker pain and disability. A work-related musculoskeletal disorder is an injury to the muscles, tendons and/or nerves of the upper body either caused or aggravated by work. Other names used to describe work-related musculoskeletal disorders include repetitive motion injuries, repetitive strain injuries, cumulative trauma disorders, soft tissue disorders and overuse syndromes.

One out of every 10 Canadian adults had a repetitive strain injury (RSI) serious enough to limit their normal activities in 2000/01, according to a new study published today in Health reports , which shows that RSIs are affecting a growing number of adults.

An estimated 2.3 million people aged 20 or older reported having had an RSI at some point in the 12 months prior to their participation in the Canadian Community Health Survey, for which data collection began in September 2000.

This marked an increase in the prevalence of RSIs during the late 1990s. In 1996/97, 8% of adults reported the problem, according to the National Population Health Survey. The proportion hit 10% in 2000/01. Work-related activities were most often the cause.

Repetitive strain injury is an umbrella term for a group of disorders usually caused by repetitive movements that affect the muscles, tendons and nerves. Unlike other injuries, which occur at a single point in time, RSIs develop over an extended period.

In 2000/01, men and women were almost equally likely to report an RSI, although since 1996/97, the percentage of women sustaining such injuries rose faster than the percentage of men. For women, the increase was from 7.9% to 10.3%, compared with an increase from 8.2% to 9.9% for men.

STATISTICS & INFORMATION: SURGERY

The fail rate for carpal tunnel surgery is over 50%. Many times I meet women who have undergone multiple surgeries, still unable to work and struggling with chronic pain. (Sportstouch.com / Kate Montgomery

Carpal tunnel surgery has about a 57% failure rate following patients from 1-day to 6-years. At least one of the following symptoms re-occurred during this time: Pain, Numbness, Tingling sensations. Source: Nancollas, et al, 1995. J. Hand Surgery.

Oftentimes, the surgery fails to produce any lasting help. A published study by Dr. Strasberg, at the Washington University School of Medicine, reported some startling results. This study, involving patients requiring a second surgery for CTS, revealed that only 53% of the patients showed significant improvement in their symptoms .

Another study produced by the Washington School of Public Health and Community Medicine showed that relief from pain was complete or modest in 86% of the patients. Of the patients studied, only 67% were able to return to their old jobs whereas, 15% had to change jobs and the remainder did not return to work.MUST READ THIS BY ONE OF THE MOST RENOUND MEDICAL JOURNALS- JAMA!!! http://www.mit.edu/people/wchuang/unix/CTS/CTS_Surgery.txt

School of Medicine researchers surveyed 166 people who had undergone the surgery during an eight-year period. Eighty-one percent of those who had received workers' compensation reported residual symptoms , compared with 49 percent of those who had not.

The former returned to work 12 weeks after their surgeries, whereas the latter took only three weeks to get back on the job."So our study suggests that the workers' compensation system in some way affects outcomes of carpal tunnel surgery," said Philip E. Higgs, M.D., assistant professor of surgery and of occupational therapy. Higgs was lead author of the study, which was described in a recent issue of the Journal of Hand Surgery.

The two groups differed in job stability as well as in time off work and presence of residual symptoms, the survey found. Half of the workers' compensation patients had changed jobs since the surgery , and 65 percent of these attributed the change to carpal tunnel syndrome. Only one-quarter of the other patients had changed jobs, and only 14 percent of these blamed the switch on residual symptoms.

The author of the book, Occupation and Disease: How Social Factors Affect the Conception of Work Related Disorders, says that a very large number of the 240,000 carpal tunnel operations performed in the U.S. each year are useless or worse. While doctors claim an 85-95 percent success rate for their surgeries, another expert in the field says that among the patients she has spoken to the rate of satisfaction was closer to one percent. Stephanie Barnes, director of the Association for Repetitive Motion Syndromes in Santa Rosa.

Many patients are undergoing multiple surgeries, which can cause complications ranging from excessive scar tissue overgrowth (re- compressing the nerve tunnel) to surgical injuries that leave the fingers totally devoid of sensation. United Press, August 8, 1996.

Other researchers are warning that misdiagnoses are more often the rule than the exception. "By the time we've completely mutilated the person, maybe then we'll decide it's not carpal tunnel syndrome after all," says one epidemiologist. Barbara Silverstein, research director at the Washington State Department of Labor and Industries, Olympia, Washington.

STATISTICS: TYPING

If you type 40 words a minute : you press 12,000 keys per hour or 96,000 keys per 8-hour day.

Approximately 8 ounces of force is necessary to depress one key.

Almost 16 tons of force will be exercised by your fingers.

Note on computer users and typists: Repetitive typing and key entry is highly associated with missing work due to CTS. The risk for CTS in this group, however, is still much lower than with occupations involving heavy labor. One small 2001 study reported that nerve conduction tests on frequent computer users showed the same rate of CTS (3.5%) as in the general population. However, 10% of the computer users complained of CTS symptoms and 30% reported tingling and burning in the hand. The typing speed may affect risk. For example, the fingers of typists whose speed is 60 words per minute exert up to 25 tons of pressure each day . And in one, study typists with CTS struck the keys with greater force than those without the disorder did.

"According to the U.S. Department of Labor, Occupational Safety and Health Administration (OSHA), repetitive strain injuries are the nation's most common and costly occupational health problem, affecting hundreds of thousands of American workers, and costing more than $20 billion a year in workers compensation. "
Treatments consist of both invasive and conservative therapy.

Invasive treatments include cortisone injections and surgical procedures while conservative treatments include massage therapy, stretching, exercising, ultrasound, sine wave, cold laser, physical therapy, chiropractic, hot/cold therapy and more.
