IN THE SUPREME COURT OF TENNESSEE

AT NASHVILLE

November 2, 2016 Session, Heard at Jackson

JUDY KILBURN v. GRANITE STATE INSURANCE COMPANY, ET AL.

Appeal from the Chancery Court for Williamson County

No. 37184 Michael Binkley, Judge

No. M2015-01782-SC-R3-WC – Filed April 10, 2017

___________________________________

In this workers‟ compensation case, Charles Kilburn sustained several injuries from a 

motor vehicle accident. He underwent cervical spine surgery to resolve his neck injury 

complaints. His authorized physician also recommended lumbar spine surgery to combat 

his back pain, but that request was denied through the utilization review process. Mr. 

Kilburn took oxycodone to alleviate his back pain, and his treating physician referred him 

to a pain management clinic. Six months after the cervical spine surgery, Mr. Kilburn

died due to an overdose of oxycodone combined with alcohol. After a bench trial, the 

chancery court found that the death was compensable. Mr. Kilburn‟s employer appealed. 

The appeal was initially referred to a Special Workers‟ Compensation Appeals Panel, but 

we later transferred the case to the Supreme Court for review. After examining the 

record, the parties‟ arguments, and the applicable law, we reverse the judgment of the 

chancery court.

OPINION

I. Facts and Procedural History
- 2 -

On November 6, 2008, Charles Kilburn, a trim carpenter, was severely injured in a 

motor vehicle accident during the course of his employment. His employer was Ryan 

Brown (“Employer”). Kilburn v. Granite State Ins. Co., No. M2011-00011-WC-R3-WC, 

2011 WL 10621663, at *1 (Tenn. Workers Comp. Panel Nov. 30, 2011).1 As a result of 

the accident, Mr. Kilburn incurred fractures to the C3 and C4 vertebrae in his neck and 

disc herniations at the L4-5 and L5-S1 areas of his lower back. Dr. Jacob Schwarz, a 

neurosurgeon, performed an anterior cervical discectomy and surgical fusion of the C3 

and C4 vertebrae on July 29, 2009, which improved Mr. Kilburn‟s neck pain. After 

physical therapy and an epidural steroid injection, Mr. Kilburn still complained of severe 

back pain when bending forward or backward, pain that was more severe on his left side 

than on the right, and lower extremity pain. Mr. Kilburn also felt heaviness in his legs 

after walking for a short period of time such that he would have to sit down, which Dr. 

Schwarz opined was a symptom of neurogenic claudication. As a result, Dr. Schwarz 

recommended surgery to the L4-5 and L5-S1 areas of Mr. Kilburn‟s lower back. 

However, Mr. Kilburn‟s insurance company denied coverage for the surgery due to a 

peer review by three physicians disagreeing with Dr. Schwarz‟s findings. The insurance 

company also denied Dr. Schwarz‟s recommendation for epidural steroid injections. Dr. 

Schwarz then referred Mr. Kilburn to a pain management clinic and wrote a letter to Mr. 

Kilburn‟s insurance adjustor asserting that Mr. Kilburn‟s pain was debilitating enough to

prevent him from returning to work.

On January 4, 2010, Mr. Kilburn was evaluated by Dr. William Leone, a pain 

management specialist. Dr. Leone‟s notes reflect that he was concerned with Mr. 

Kilburn‟s consumption of alcohol while taking his medication. Mr. Kilburn also 

admitted that because he felt the medication was no longer effective, he was taking two 

opioid tablets at once even though he had only been prescribed one tablet at a time. The 

urinary drug screen conducted that day showed the presence of both alcohol and the 

opioid medication. As a result, Dr. Leone recommended weaning Mr. Kilburn off the 

opioid medication and trying other options. Dr. Leone prescribed 350 mg of Soma twice 

daily and 15 mg of oxycodone four times daily. As part of his treatment, Mr. Kilburn

initialed and signed an agreement stating, “I will control my usage of narcotic 

medications as directed by the attending physician. There are no exceptions. If 

medication is inadequate for [my] pain level, [I] must call before adjusting dosage.” 

On January 11, 2010, Dr. Tarek Elalayli performed an independent medical 

evaluation of Mr. Kilburn. Dr. Elalayli gave Mr. Kilburn a four percent whole body 

 

1 This is the second appeal in this case. The first appeal concerned the trial court‟s denial of Ms. 

Kilburn‟s motion to amend the complaint to assert that Mr. Kilburn‟s death was compensable because it 

was related to his work injury. Kilburn, 2011 WL 10621663, at *1. The Special Workers‟ Compensation 

Appeals Panel to which the prior appeal was referred reversed the denial of the motion to amend and 

remanded the case to the lower court for further consideration. Id.

impairment rating for the remaining cervical spine issues and a two percent whole body 

impairment rating for the lower back pain. Dr. Elalayli also voiced concerns that Mr. 

Kilburn was magnifying his symptoms because Dr. Elalayli felt that Mr. Kilburn‟s 

subjective symptoms outweighed the objective results of his physical examination and 

the MRI. Dr. Elalayli recommended reducing the oxycodone dose and suggested that Mr. 

Kilburn return to work.2

During the trial, Phillip Manning, Mr. Kilburn‟s brother-in-law, and Judy Kilburn, 

Mr. Kilburn‟s wife, explained that prior to the 2008 motor vehicle accident, Mr. Kilburn

was friendly and outgoing and was very active. However, after the injury and neck 

surgery, Mr. Kilburn‟s lower back pain seemed to Mr. Manning to be “[p]retty bad” and 

uncomfortable, and Mr. Kilburn was “upset” about not being able to have the lower back 

surgery. Mr. Manning opined that Mr. Kilburn “had anxiety about not having medication 

and not having the surgery” but that Mr. Kilburn never appeared hopeless, just ready to 

be back to full capacity. Mr. Manning stated that Mr. Kilburn started skipping doses of 

his medication because he was scared that he was going to run out of the medication and 

would be unable to obtain more. 

Mr. Manning and Ms. Kilburn both explained that after the injury, Mr. Kilburn

still cared for the children, got them up and ready for school in the mornings, and helped 

them with their homework while Ms. Kilburn was working in the evenings. Mr. Kilburn

also cooked meals, performed various household duties, and ensured that the children 

performed their “chores,” which Ms. Kilburn explained were often the tasks that Mr. 

Kilburn could not accomplish. In addition, Mr. Kilburn often drove to his parents‟ house 

and helped care for his mother who was ailing from cancer. Mr. Manning estimated that 

in the six months prior to Mr. Kilburn‟s death, he saw Mr. Kilburn ten to fifteen times at 

family gatherings, when they ate at restaurants together, and “around town.” 

However, Ms. Kilburn stated that after the accident, Mr. Kilburn “felt worthless 

because he couldn‟t get out and earn a living and take care of his family.” Ms. Kilburn 

asserted that Mr. Kilburn was “still in a lot of pain,” “seemed somewhat depressed,” and 

could only achieve intermittent sleep at night. Ms. Kilburn elaborated that she believed 

Mr. Kilburn supplemented his medication with alcohol because it helped with his pain 

when he was skipping doses of his medication in an attempt to make the medicine last 

longer. However, Ms. Kilburn conceded that to her knowledge, Mr. Kilburn had never 

been without medication. Ms. Kilburn stated that before the accident, Mr. Kilburn would 

 

2 We note, and the parties indicate, that Dr. Elalayli‟s records show that Mr. Kilburn was 

receiving a 50 mg dose of oxycodone four times a day when, in fact, he was prescribed 15 mg of 

oxycodone four times a day. It is unclear if this was merely a clerical error or if this was the reasoning

behind Dr. Elalayli‟s recommendation to reduce the amount of oxycodone prescribed to Mr. Kilburn.

sometimes drink during the week but drank more on the weekends when he was not 

working. Ms. Kilburn explained that after the accident, Mr. Kilburn did not drink as 

much but that “he would drink a beer here or there, a couple, maybe. He drank maybe a 

six pack sometimes on weekends.” She also asserted that she had directed Mr. Kilburn

not to drink alcohol while on his medication. While Ms. Kilburn agreed that Mr. Kilburn

had never been treated for anxiety or depression, she opined that he suffered from those 

ailments.

Ms. Kilburn found Mr. Kilburn unresponsive in bed on the morning of January 28, 

2010. The medical examiner‟s report specifically stated that the cause of death was acute 

oxycodone toxicity with contributory causes of hypertension, tobacco use, and alcohol 

use. His death was deemed an accident. Mr. Kilburn was forty years old at the time of 

his death.

At trial, Dr. Alistair Finlayson and Dr. Jeffrey Hazlewood testified by deposition

about their review of Mr. Kilburn‟s medical records. Dr. Finlayson was a psychiatrist

with a subspecialty in addictions and a clinical associate professor in psychiatry at 

Vanderbilt University Medical Center. He was also the medical director of the 

Comprehensive Assessment Program at Vanderbilt, which evaluates professionals to 

determine if they are “fit for duty.” He performed a records review at the request of Ms. 

Kilburn. Dr. Finlayson stated that it was “more likely than not” that Mr. Kilburn was 

suffering from severe pain or anxiety at the time of his death and that it was “certainly 

possible” that those conditions diminished Mr. Kilburn‟s faculties and contributed to his 

risk of overdose. He further asserted that “it‟s probably the most likely explanation.” Dr. 

Finlayson explained that when a person takes medications like oxycodone, they can 

develop a psychological dependency on the medication and that if a person develops this 

dependency and does not have enough medication, it can result in increased pain. Dr. 

Finlayson differentiated between a dependency on opiates and an addiction. He opined 

that Mr. Kilburn was not suffering from true addiction but rather a dependency on the 

medication. He also opined that in a situation like Mr. Kilburn‟s where there was 

potential for an interruption in his treatment, it was “very possible” that the situation 

would cause a person anxiety.

Dr. Finlayson stated that when a person is used to taking an opioid but then takes 

less or stops taking the medication, “the pain is intensified and anxiety is intensified as a . 

. . withdrawal.” Dr. Finlayson stated that drugs like OxyContin, Soma, and Valium3all 

 

3 While we note that Dr. Finlayson discusses Mr. Kilburn‟s consumption of Valium several times 

during his testimony, in our review of the record, we find only limited information about Mr. Kilburn‟s 

taking Valium (also known as diazepam). The Fred‟s Pharmacy records show that on November 7, 2008, 

the day after Mr. Kilburn‟s motor vehicle accident, Dr. Schwarz prescribed Mr. Kilburn ninety tablets of 

Valium to be taken in thirty days. Also, in his medical records review report, Dr. Hazlewood states that 
- 5 -

contribute to feelings of depression and hopelessness, which could potentially influence a 

person‟s judgment. He further opined that he did not believe that Mr. Kilburn was 

addicted to his medication but rather that “it [was] possible that . . . he was so 

discouraged, depressed, anxious about what was going to happen and experiencing some 

withdrawal symptoms that he . . . took maybe more medication than he intended to, 

combined with more alcohol than he intended to.” However, Dr. Finlayson agreed that 

there was nothing in the record indicating that a treating physician had diagnosed Mr. 

Kilburn with anxiety. When asked what proof or evidence there was that Mr. Kilburn

suffered from anxiety, Dr. Finlayson responded, “It is a guess, an educated guess from 

dealing with similar patients, dealing with people who receive similar prognoses and 

people who are withdrawing from alcohol, Valium, Soma and OxyContin. It‟s 

conjecture[,] but . . . it wouldn‟t be uncommon.” 

Dr. Hazlewood was a board-certified physician in physical medicine, 

rehabilitation, and pain management and had been practicing in pain management for 

nineteen years. He conducted a records review at the request of Employer. Dr. 

Hazlewood agreed with Dr. Leone‟s recommendation to slowly decrease Mr. Kilburn‟s 

intake of narcotics, rather than increasing the dosage, because of Mr. Kilburn‟s building 

tolerance to the medication and because of Mr. Kilburn‟s use of alcohol. He opined that 

taking 60 mg of oxycodone daily along with consuming alcohol was inadvisable. When 

discussing the effect of Mr. Kilburn‟s pain and anxiety on his judgment, Dr. Hazlewood 

stated that while acute pain such as breaking several bones at one time can cloud a 

person‟s judgment, he did not think that chronic pain such as Mr. Kilburn‟s could cloud a 

person‟s judgment. Dr. Hazlewood agreed that anxiety, depression, and suicidal 

ideations could cloud a person‟s judgment but stated that he was not qualified to state 

whether pain can cause an anxiety disorder. Dr. Hazlewood stated that there were 

warning signals that Mr. Kilburn may have been developing an addiction to opiates and 

that some “true addict[s]” can “lose perception” or control over the amount of medication 

they consume. However, he explained that an addictionologist or psychiatrist would be 

better able to make that determination. He further opined that there was nothing in the 

record to show that Mr. Kilburn suffered from anxiety or withdrawal symptoms that 

could cloud his judgment, especially given that Mr. Kilburn would refrain from taking his 

medication periodically. Dr. Hazlewood asserted that there was no objective evidence of 

anxiety, an inability to make sound decisions, severe or debilitating pain, or altered 

judgment. 

 

during an emergency room visit on July 29, 2009, Mr. Kilburn reported taking Valium. However, Dr. 

Hazlewood also stated in his report that he did not “see any indication that [Valium] was being used at the 

time of death” on January 28, 2010. 
- 6 -

Both doctors agreed that while tobacco use and hypertension were tangentially 

related to Mr. Kilburn‟s health and ability to withstand the acute oxycodone toxicity, Mr. 

Kilburn‟s use of alcohol was the primary contributing factor. 

After hearing the evidence, the trial court issued its decision as a written 

memorandum. The trial court accredited the opinion of Dr. Finlayson over that of Dr. 

Hazlewood. The court found that Ms. Kilburn had sustained her burden of proof to show 

that Mr. Kilburn‟s death was a direct and natural consequence of his work injury. It 

awarded workers‟ compensation death benefits to Ms. Kilburn. Employer has timely 

appealed, asserting that the evidence preponderates against the trial court‟s finding of 

compensability and that Mr. Kilburn‟s conduct constituted an independent intervening 

cause of his death. 

II. Standard of Review

The standard of review of issues of fact in a workers‟ compensation case is de 

novo upon the record of the trial court accompanied by a presumption of correctness of 

the findings, unless the preponderance of evidence is otherwise. Tenn. Code Ann. § 50-

6-225(a)(2) (2014). When the trial judge has had the opportunity to observe a witness‟s 

demeanor and to hear in-court testimony, we give considerable deference to factual 

determinations made by the trial court. Madden v. Holland Grp. of Tenn., Inc., 277 

S.W.3d 896, 898 (Tenn. 2009) (citing Tryon v. Saturn Corp., 254 S.W.3d 321, 327 

(Tenn. 2008)). When the issues involve expert medical testimony given by deposition,

the weight and credibility must be drawn from the contents of the depositions; therefore, 

as a reviewing court, we may draw our own conclusions with regard to those issues. 

Foreman v. Automatic Sys., Inc., 272 S.W.3d 560, 571 (Tenn. 2008) (citing Orrick v. 

Bestway Trucking, Inc., 184 S.W.3d 211, 216 (Tenn. 2006)). A trial court‟s conclusions 

of law are reviewed de novo with no presumption of correctness. Seiber v. Reeves 

Logging, 284 S.W.3d 294, 298 (Tenn. 2009) (citing Goodman v. HBD Indus., Inc., 208 

S.W.3d 373, 376 (Tenn. 2006); Layman v. Vanguard Contractors, Inc., 183 S.W.3d 310, 

314 (Tenn. 2006)).

III. Analysis

“It is well settled in Tennessee that a plaintiff in a worker‟s compensation suit has 

the burden of proving every element of the case by a preponderance of the evidence.” 

Elmore v. Travelers Ins. Co., 824 S.W.2d 541, 543 (Tenn. 1992) (citing Talley v. Va. Ins. 

Reciprocal, 775 S.W.2d 587, 591 (Tenn. 1989)). “In order to meet this burden, „[t]his 

Court has consistently held that causation and permanency of a work-related injury must 

be shown in most cases by expert medical evidence.‟” Id. at 543-44 (quoting Tindall v. 

Waring Park Ass’n, 725 S.W.2d 935, 937 (Tenn. 1987)). 
- 7 -

“The basic rule is that a subsequent injury, whether an aggravation of the original 

injury or a new and distinct injury, is compensable if it is the direct and natural result of a 

compensable primary injury.” Rogers v. Shaw, 813 S.W.2d 397, 399-400 (Tenn. 1991)

(citation omitted). Therefore, “„all the medical consequences and sequelae that flow from 

the primary injury are compensable.‟” Anderson v. Westfield Grp., 259 S.W.3d 690, 696

(Tenn. 2008) (quoting 1 Larson’s Workers’ Compensation Law § 10.01 (2004)). 

However, that rule has a limit that “hinges on whether the subsequent injury is the result 

of independent intervening causes, such as the employee‟s own conduct.” Id. at 696. 

Stated another way, “„the progressive worsening or complication of a work-connected 

injury remains compensable so long as the worsening is not shown to have been 

produced by an intervening nonindustrial cause.‟” Id. at 697 (quoting 1 Larson’s 

Workers’ Compensation Law § 10.01 (2004)). The Anderson court provided several 

examples of cases in which the injured employee‟s conduct constituted an independent 

intervening cause that rendered the subsequent injury to be non-compensable: Simpson v. 

H.D. Lee Co., 793 S.W.2d 929, 931-32 (Tenn. 1990) (concluding that medication taken 

contrary to instructions constituted an intervening cause); Guill v. Aetna Life & Cas. Co., 

660 S.W.2d 42, 43-44 (Tenn. 1983) (determining that injecting medication contrary to 

medical instructions was an intervening cause); and Jones v. Huey, 357 S.W.2d 47, 49-50 

(Tenn. 1962) (deciding that the negligent operation of a tractor after a work-related back 

injury was not compensable). The Anderson Court adopted the reasoning of Jones v. 

Huey and stated: 

[W]e reject the employee‟s argument that only reckless or intentional 

misconduct can constitute an intervening cause. Instead, we find, as we did 

in Jones, that negligence is the appropriate standard for determining 

whether an independent intervening cause relieves an employer of liability 

for a subsequent injury purportedly flowing from a prior work-related 

injury.

Anderson, 259 S.W.3d at 698-99. Application of the intervening cause principle is not an 

affirmative defense but, rather, is a “way of assessing the scope of an employer‟s liability 

for injuries occurring after a compensable injury.” Id. at 697; see Shelton v. Cent. Mut. 

Ins. Co., No. E2008-00553-WC-R3-WC, 2009 WL 1110476, at *3 (Tenn. Workers 

Comp. Panel Apr. 24, 2009). 

Applying these principles, we now address the present case. Based on the 

testimony at trial, it appears uncontroverted that Mr. Kilburn died from acute oxycodone 

toxicity with contributory causes of hypertension, tobacco use, and alcohol use and that at 

times, Mr. Kilburn took more of his opioid medication than prescribed and consumed 

alcohol while taking the pain medication. It also appears that no one contests that Mr. 
- 8 -

Kilburn took his medication in contravention of his prescription and his physician‟s 

instructions. Therefore, the question at issue is whether this behavior terminated the 

causal link between Mr. Kilburn‟s work-related injury and his death. 

In Simpson, this Court concluded that when Mr. Simpson failed to take his pain 

medication in accordance with the physician‟s instructions, which caused his demise, his 

death was no longer causally related to his employment. Simpson, 793 S.W.2d at 931-32. 

Similarly, in the current case, Mr. Kilburn failed to take his opioid pain medication in 

accordance with the instructions given to him by his treating physician.

Ms. Kilburn argues that Mr. Kilburn‟s death was still a direct and natural result of 

his work-related injury, in spite of his overconsumption of his pain medication and his 

drinking alcohol while taking his medication, because Mr. Kilburn had suffered from 

severe pain and anxiety that diminished his faculties to the extent that he was at risk to 

inadvertently overdose on his pain medication. In support of this contention, Ms. Kilburn 

cites Shelton v. Central Mutual Insurance Co., E2008-00553-WC-R3-WC, 2009 WL 

1110476 (Tenn. Workers Comp. Panel Apr. 24, 2009), and Wheeler v. Glen Falls 

Insurance, 513 S.W.2d 179 (Tenn. 1974).

In Shelton, a workers‟ compensation panel reversed a trial court‟s grant of 

summary judgment to the employer where the injured employee‟s death was caused by 

an accidental overdose of prescription medication because the deceased‟s widow 

produced sufficient evidence to establish, “barely,” the existence of a genuine issue of 

material fact. Shelton, 2009 WL 1110476, at *6. As in the first appeal in this case, 

Shelton was decided according to the standard of review applicable to summary 

judgments. While at first blush these facts seem applicable to the case at hand, the 

current case comes to us after a full trial on the merits. Therefore, the difference in 

appellate review between Shelton, where the court had to determine if there was a 

genuine issue as to any material fact, and this case, where the Court must analyze if Ms. 

Kilburn proved that Mr. Kilburn‟s death was a direct and natural result of his workrelated injury by a preponderance of the evidence, makes Shelton inapplicable to the case 

at bar.

Ms. Kilburn also cites Wheeler v. Glen Falls Insurance, 513 S.W.2d 179 (Tenn. 

1974), in support of her position. In that case, an employee suffered a compensable 

injury to his back as a result of a fall. Id. at 180. Employee was an alcoholic, and after 

his injury, he increased his alcohol consumption, which ultimately caused his death. Id. 

The trial court awarded benefits. Id. Applying the material evidence standard of review 

in effect at that time, the Supreme Court affirmed, holding that there was material 

evidence to support the trial court‟s finding that pain from the work injury had aggravated 

the pre-existing alcoholism. Id. at 184. It is noteworthy that the standard applicable to 
- 9 -

subsequent injuries at that time was that a claim was only considered an independent 

intervening cause if the subsequent injury was the result of willful or deliberate conduct. 

Id. at 183. Anderson specifically modified that standard to include an employee‟s 

negligence as a bar to recovery. Anderson, 259 S.W.3d at 698-99. Finally, we note that 

the Court in Wheeler relied heavily on the exacerbation of a prior illness, alcoholism, 

going so far as to compare the employee‟s increase in alcohol consumption to the 

acceleration of cancer. Wheeler, 513 S.W.2d at 184 (citing Boyd v. Young, 246 S.W.2d 

10 (Tenn. 1951) (concluding that the death of an employee was compensable when the 

primary injury accelerated the growth of the pre-existing disease)). Mr. Kilburn in the 

present case did not suffer from a prior illness that was then exacerbated by his workrelated injury; rather, after the accident, it appears that his drinking continued in a similar 

manner as prior to the accident, but he was then consuming his pain medication in 

addition to the alcohol. For the reasons listed above, we conclude that Wheeler is not 

controlling in the case at hand.

Finally, in support of her assertion that Mr. Kilburn‟s death was a direct and 

natural result of his work-related injury, Ms. Kilburn presented the deposition testimony 

of Dr. Finlayson. Because both Dr. Finlayson and Dr. Hazlewood testified by deposition, 

we may draw our own conclusions regarding the weight and credibility of their 

testimony. See Foreman, 272 S.W.3d at 571 (citing Orrick, 184 S.W.3d at 216). As set 

out above, Dr. Finlayson testified about the likelihood that Mr. Kilburn suffered anxiety 

due to his use, and the possible interruption of his use, of opioid medication that clouded 

his judgment. While we respect that Dr. Finlayson is a psychiatrist with a subspecialty in 

addictions, we also note that neither Dr. Finlayson nor Dr. Hazlewood had the 

opportunity to examine Mr. Kilburn. When forming their expert opinions, both doctors 

relied on Mr. Kilburn‟s medical records. Likewise, both doctors had to rely on the 

testimony of Mr. Manning and Ms. Kilburn, each of whom presented internally 

contradictory testimony concerning Mr. Kilburn‟s mental state. While Dr. Finlayson‟s 

specialty was more instructive on the issue of Mr. Kilburn‟s mental state at the time of 

his overdose, Dr. Finlayson‟s testimony was very equivocal. During his deposition Dr. 

Finlayson used phrases like: “it was possible,” “it is a guess, an educated guess,” “[i]t‟s 

conjecture[,] but . . . it wouldn‟t be uncommon.” Dr. Finlayson also agreed that there 

was nothing in the record showing where a treating physician had diagnosed or even 

noted that Mr. Kilburn was suffering from anxiety. 

Dr. Hazlewood similarly noted that there was nothing in the medical records that 

showed that Mr. Kilburn suffered from anxiety or withdrawal symptoms that clouded Mr. 

Kilburn‟s judgment. In fact, Dr. Hazlewood asserted that there was no objective 

evidence of anxiety, an inability to make sound decisions, severe or debilitating pain, or 

altered judgment. While Dr. Hazlewood opined that Mr. Kilburn exhibited some warning 

signs of an addiction to opiates and explained that some “true addict[s]” can “lose 
- 10 -

perception” or control over the amount of medication they consume, he explained that an 

addictionologist or psychiatrist would be better able to make that determination. To that 

end, Dr. Finlayson, a psychiatrist, clarified that he did not believe that Mr. Kilburn was 

an addict. 

Based on the above analysis, we conclude that the evidence preponderates against 

the trial court‟s findings.4 We conclude that, like the employee in Simpson, Mr. Kilburn

failed to take his pain medication in accordance with his physician‟s instructions, which 

ultimately caused his demise. See Simpson, 793 S.W.2d at 931-32. Therefore, his death 

was no longer causally related to his work-related injury, and his overdose was an 

independent intervening cause.

CONCLUSION

In summary, we conclude that Mr. Kilburn‟s failure to consume his medication in 

accordance with his doctor‟s instructions was an independent intervening cause. As such, 

we reverse the judgment of the trial court. The costs of this appeal are taxed to the 

plaintiff, Judy Kilburn.

ROGER A. PAGE, JUSTICE

 

4 We emphasize the narrowness of the holding in this case. The analysis and holding are very 

fact specific to the case at bar. We do not conclude that an individual can never prove that an overdose is 

the direct and natural result of the original compensable injury when a dependency or addiction to 

narcotics develops. We merely conclude that based on the facts and testimony in this case, the evidence 

preponderates against the trial court‟s finding that Mr. Kilburn‟s death was a direct and natural 

consequence of his original injury.
