I.
Occupational Disease \& Injury
The underlying issue presented in this case is whether the employee sustained an incident of occupational disease in the nature of bilateral carpal tunnel syndrome, in her employment with Price Cutter. The parties offer differing and competing medical opinions from examining physicians.
The term "occupational disease" is defined in Section 287.067, RSMo. In pertinent part, this statute states:
- In this chapter the term "occupational disease" is hereby defined to mean, unless a different meaning is clearly indicated by the context, an identifiable disease arising with or without human fault out of and in the course of the employment. Ordinary diseases of life to which the general public is exposed outside of the employment shall not be compensable, except where the diseases follow as an incident of an occupational disease as defined in this section. The disease need not to have been foreseen or expected but after its contraction it must
appear to have had its origin in a risk connected with the employment and to have flowed from that source as a rational consequence.
- An injury by occupational disease is compensable only if the occupational exposure was the prevailing factor in causing both the resulting medical condition and disability. The "prevailing factor" is defined to be the primary factor, in relation to any other factor, causing both the resulting medical condition and disability. Ordinary, gradual deterioration or progressive degeneration of the body caused by aging or by the normal activities of day-to-day living shall not be compensable.
- An injury due to repetitive motion is recognized as an occupational disease for purposes of this chapter. An occupational disease due to repetitive motion is compensable only if the occupational exposure was the prevailing factor in causing both the resulting medical condition and disability. The "prevailing factor" is defined to be the primary factor, in relation to any other factor, causing both the resulting medical condition and disability. Ordinary, gradual deterioration, or progressive degeneration of the body caused by aging or by the normal activities of day-to-day living shall not be compensable.
In the case of Vickers v. Missouri Department of Public Safety, 283 S.W.3d 287 (Mo. App. W.D. 2009), the court discussed the burden of proof and evidence necessary for an employee to establish that an occupational disease is compensable under Section 287.067, as the law existed prior to the 2005 amendments. The court stated as follows, 283 S.W.3d at 292 et seq.:
In proving a causal connection between the conditions of employment and the occupational disease, the claimant bears the burden of proof; to prove causation it is sufficient to show a recognizable link between the disease and some distinctive feature of the job . . . and there must be evidence of a direct causal connection between the conditions under which the work is performed and the occupational disease. However, the cause and development of an occupational disease is not a matter of common knowledge. There must be medical evidence of a direct causal connection. . . . 'A claimant must submit medical evidence establishing a probability that working conditions caused the disease, although they need not be the sole cause.' . . . Even where the causes of the diseases are indeterminate, a single medical opinion relating the disease to the job is sufficient to support a decision for the employee.'
Notably, however, the court's discussion of proving causation in Vickers must be viewed in context of Section 287.067, RSMo as amended in 2005. The Amendments to this statute changed the causation factor to require that the occupational exposure be the "prevailing factor" in relation to causation. See, Lawson v. Ford Motor Co., 217 S.W.3d 345 (Mo. App. E.D., 2007). In discussing this new requirement, the court in Lawson stated,
The legislature amended several sections of the Workers' Compensation Act in 2005. In particular, portions of section 287.067 and 287.020 were rewritten. Specifically, section 287.067 .2 discusses when an injury by occupational disease
is considered compensable. Prior to 2005, the section stated that such an injury will be compensable if it "is clearly work related and meets the requirements of an injury which is compensable as provided in subsections 2 and 3 of section 287.020." Subsections 2 and 3 of section 287.020 previously contained definitions for "accident" and "injury." Prior to 2005, those definitions included language which concluded that an injury was compensable if it is work related, which occurs if work was a "substantial factor" in the cause of the disability.
After the 2005 amendments to the statutes, the definition of a compensable injury by occupational disease was changed to use the language "prevailing factor" in relation to causation. Specifically, section 287.067.2 states:
An injury by occupational disease is compensable only if the occupational exposure was the prevailing factor in causing both the resulting medical condition and disability. The "prevailing factor" is defined to be the primary factor, in relation to any other factor, causing both the resulting medical condition and disability. Ordinary, gradual deterioration, or progressive degeneration of the body caused by aging or by the normal activities of day-to-day living shall not be compensable.
Section 287.020.3 defines "injury" using similar terms.
217 S.W.3d at 349-350 et seq.
In this case, there is "biological plausibility" that the demands of the job in Ms. Quast's employment with Price Cutter caused her to suffer repetitive or cumulative trauma to her right and left hands, which caused her to sustain an injury in the nature of carpal tunnel syndrome in both her right and left hands. The prevailing factor in relation to causation is the demands of the job that required her to perform hand intensive activity, including a lot of computer work, and work with her hands as a cashier in her employment with the employer, while working as an employee of Price Cutter.
The evidence presented in this case established the following facts. In or around 2006 Ms. Quast obtained employment with Price Cutter, working in a variety of positions, including work as a cashier, bookkeeper, and guest relations manager/front-end manager. Ms. Quast's initial employment involved work as a cashier, which required her to perform cashier duties. In this position she utilized a belt scanner to process purchases. In March 2007 she assumed the duties of a bookkeeper. As a bookkeeper, she had a desk and an office. She would make up the cash register tills for the cashiers, count the money, check the cash register tills, and record her bookkeeping entries on a computer. Later, on or about October 18, 2009, she received a promotion to the position of Guest Relations Manager ("GRM"). In this position she was responsible for supervising and assisting the cashiers, assisting and directing customers, answering the phone, and working the service desk handling returns, the sale of money orders and Western Union wire transfers, etc. Additionally, while working as a bookkeeper and as Guest Relations Manager she continued to perform cashier duties.
This employment required Ms. Quast to perform repetitively and cumulatively hand intensive work. Notably, the work as a cashier required Ms. Quast to perform pinching maneuvers, as she lifted and scanned grocery items. The repetitive and cumulative nature of this work activity caused pressure to present in the carpal tunnel region, and this pressure causes damage to the nerve. The longer the pressure occurs in the carpal tunnel region the injury becomes more progressive with greater damage to the nerve.
In or around 2011, and while employed by Price Cutter, Ms. Quast began to experience pain and numbness in both of her hands. In light of the continuing and progressive nature of this pain, Ms. Quast presented to Dr. Middleton with multiple concerns, including complaints of bilateral hand pain. Dr. Middleton initially thought Ms. Quast's problems were related to osteoarthritis. Ms. Quast continued to receive follow-up medical treatment with Dr. Middleton for multiple medical concerns, including bilateral hand pain, which Dr. Middleton identified as being "suspicious for osteoarthritis."
In September 2011 Ms. Quast discussed with Dr. Middleton bilateral complaints of pain in her hands, and in particular complaints involving her right hand. During this office visit Ms. Quast described performing hand intensive activity, including a lot of computer work, and work with her right hand as a cashier. Notably, the complaints of pain included numbness in the first three fingers of her right hand. Based on his examination of Ms. Quast, dated September 22, 2011, Dr. Middleton described the numbness as being in the median nerve distribution and suspected carpal tunnel syndrome. Although providing or offering a suspected diagnosis of carpal tunnel syndrome, Dr. Middleton did not indicate or provide an opinion as to the cause of the medical condition, and in particular did not address the question of whether Ms. Quast had sustained a work-related injury.
In providing treatment for the complaints of hand pain, Dr. Middleton provided Ms. Quast with a handout on stretching exercises, and directed Ms. Quast to wear a "wrist splint as needed." In this regard, Dr. Middleton prescribed a hand/wrist brace, which Ms. Quast wore. Additionally, Dr. Middleton discussed options for anti-inflammatory medications, but expressed hesitancy because of Ms. Quast's hypertension. Otherwise, Ms. Quast does not appear to have received any additional treatment for this medical concern.
Although time has passed since getting treatment for this bilateral hand pain, Ms. Quast continues to present with pain in both hands, as well as numbness in her index, middle and ring fingers. The right index finger is constantly numb. Further, she experiences pain into the forearm and elbow, mostly on the right.
After consideration and review of the evidence, I find and conclude that the employee's testimony was credible and consistent with the medical records, reports and other documents introduced into evidence, which demonstrated a long history of repetitive and cumulative hand intensive activity. This employment caused the employee to suffer repetitive and cumulative trauma to her right and left hands, and this occupational exposure was the prevailing factor in causing the employee to suffer bilateral carpal tunnel syndrome, and thus an occupational disease as the term is defined in Section 287.067, RSMo. Further, to the extent there are differences in medical opinion I resolve the differences in favor of Dr. Koprivica, who I find credible, reliable and worthy of belief.
Therefore, for the foregoing reasons, I find and conclude that on or about January 4, 2012, the employee, Renee Quast, sustained an injury to her right and left hands by incident of occupational disease, which arose out of and in the course of her employment with the employer, Price Cutter.
