Doctors claim uncertainty - and do harm. - Mark P. Loftus

September 26, 2025

I took the deposition of an infectious disease doctor the other day in a Workers Compensation matter. The doctor lets call him Dr. Smith treated my client as he lay dying in a south suburban hospital. My client – Donald – was a plumber who worked for an HVAC company in the south suburbs. By way of background, prior to his death, Dennis was not the picture of health. He had battled various addictions for years prior to getting sober circa 1997. To his credit, he had been clean since. But the years of abuse had taken a toll. He had Hepatitis C and cirrhosis.

Donald and his wife Marie had been seeing the same primary care doctor[“PCP”] for years. After Donald died, the PCP contacted Marie and suggested she contact a lawyer. He explained that Donald had died of Legionnaire’s disease, a respiratory disease similar to pneumonia caused by the Legionella bacteria. The bacteria is usually inhaled from a water source. And, the PCP explained further that plumbers and other trades who routinely work around standing water, are at greater risk. Finally, the PCP explained that since Donald had been a plumber, AND that no one else in their household was sick, exposure had taken probably taken place at work. So Marie called me. After reviewing the appropriate medical records I filed the case.

I spoke with Donalds primary care doctor who told me that while he was convinced Donald had been exposed at work, he couldnt provide appropriate causation testimony. He had seen Donald prior to his hospitalization. At that time, Donald had signs of a serious respiratory disease. When antibiotics didnt help and his condition worsened, the PCP had Donald admitted, and turned his care over to the Infectious Disease specialist.

The lawyer for the employer is an honorable guy. He told me that while the medial records strongly supported a work exposure, the insurance company wanted more. So I agreed to subpoena the Infectious Disease doctor, who I presumed would provide strong causation testimony. I hadnt made that assumption lightly. In his treatment notes, Dr. Smith routinely noted that the patient worked as a plumber. And he repeatedly noted that no one else in the family was sick. Those notes suggested to me that Smith felt exposure had taken place at work.

Shortly after the subpoena was issued, I got a call from a lawyer at a prominent medical malpractice firm. I was informed he would be representing the doctor at his deposition. Those phone calls are rarely good news. Under Illinois law, the patients lawyer is permitted to discuss certain issues with the doctor before the deposition. Once the doctor hires a lawyer, there are no informal meetings before the deposition. And, invariably, a doctor who has lawyered up for his deposition is sending a very clear message “Dont count on me to help.”

On the day of the deposition, the doctor walked in at the appointed hour with his lawyer. The first thing I noticed was how young he looked. He looked more like a college sophomore than a infectious disease specialist. And early on, he was agreeable. He acknowledged the bacteria breeds in warm water and can exist in hot water tanks, air conditioning units and showers. And he confirmed that no one else in Donald’s family had become ill. And, he acknowledged that Donald’s work as a plumber would be a risk factor for exposure to the bacteria.

Then came the million dollar question did he think the exposure to legionella was work-related? He had no opinion. And he based his lack of opinion on the fact that sometimes people get exposed to legionella while working out at a health club. He testified that Donald could have been exposed while at a health club – either in the shower, hot tub or sauna area.

That testimony was absurd. With all due respect to Donald, the next time he entered a health club would have been the FIRST time Donald entered a health club. Donald stood about 5’10” and weighed nearly 275 lbs. He had high blood pressure and was borderline diabetic. Donald was not a health club guy. And to make matters worse, the doctor likely knew that. I pressed him and he acknowledged that during his treatment of Donald, he was never advised that Donald went to health clubs. But Dr. Smith wouldnt budge. He was NOT going to concede causation.

Why not? The doctor faced no legal jeopardy. All he did was provide excellent, state of the art treatment to a very sick man. The group he was affiliated with faced no legal jeopardy, nor did the hospital. An honest answer would have simply strengthened the case against the appropriate party the employer. And the employer is appropriately sheltered by Workers Compensation insurance.

Maybe he was a true believer, one of those doctors blinded by the propaganda put out by tort reformers. They mistakenly believe that medical malpractice filings are increasing and driving physicians out of Illinois. And as a result, some doctors have decided that they will never knowingly assist a personal injury lawyer and if possible, do what they can to submarine a case. Their omerta against personal injury lawyers however, is entirely misguided. The number of medical malpractice lawsuits filed in Illinois has dropped 32% since 2003. And, the number of doctors in Illinois involved in patient care has been steadily increasing since 2006.

The involvement of lawyers representing doctor/witnesses shouldnt be overlooked. That practice, to my recollection started in earnest around 15-20 years ago and appears to be the norm today. The lawyer meets with the doctor before the deposition and properly instructs the witness not to offer sweeping or unsubstantiated opinions. Do those same lawyers instruct doctors to refrain from offering appropriate causation testimony? I think most good defense lawyers leave the causation issue up to the doctor. Some of my more cynical personal injury colleagues think otherwise.

I don’t have the answer for why a doctor would would hesitate to give what appeared to be pretty obvious testimony. One fact however, cannot be argued. A doctors refusal to confirm an obvious causation link does indeed do harm to a patient and his family.

The little snippet I have provided is from Malice, an otherwise forgettable 1993 film. But this scene is worth watching, as Alec Baldwin, in all his malevolent glory, as a doctor with a God complex, melts a lawyers face.

According to online reports, Tesla ignored a $60 million dollar settlement overture in the wrongful death case that ultimately resulted in a $242 million dollar jury verdict against the car maker. The lawsuit grew out of 2019 crash where a Tesla Model S with Autopilot engaged, plowed through a Florida intersection and crashed into a Chevy Tahoe. Neima Benavides Leon and her boyfriend, Dillon Angulo were standing near the Tahoe when the Tesla crashed into it. Leon was killed and Angulo suffered serious injuries. A lawsuit was filed against Tesla, asserting that although the Autopilot feature was engaged, the vehicle did not brake. Florida law permits a monetary demand to be issued before trial. If the defendant fails to accept the demand within 30 days it is considered rejected. If the plaintiff then goes to trial and secures a verdict 25% greater than the offer, the defendant is on the hook for plaintiff’s investigative expenses and attorneys’ fees. Tesla is appealing the jury verdict, citing “substantial errors of law and irregularities at trial.”.

This important ruling got kind of lost in the news cycle. A couple weeks ago, the United States Supreme Court refused to vacate a $2.2 billion dollar ovarian cancer verdict against Johnson & Johnson[“J & J”]. The verdict was originally returned by a Missouri jury in 2018 on behalf of 22 women. The original verdict was actually $4.7 billion but a Missouri Appellate Court reduced the award to $2 billion. Each of the women claimed that there was asbestos and asbestos-laced talc in J & J talcum powder products they used, and they developed ovarian cancer as a result. Asbestos is known to cause cancer. Talc, in its raw form is often found in close proximity to naturally occurring asbestos. When J & J mined talc, that talc sometimes contained asbestos. And that asbestos sometimes found its way into J & J personal hygiene products. [In 2019, J & J recalled 33,000 bottles of J & J products after FDA testing found asbestos in test samples]. J & J, has known of the risk of asbestos contamination in talc products since the 1970’s. Some 21,000 plus ovarian cancer cases are pending against J & J throughout the United States.

Reports today say that DuPont and the State of New Jersey have reached a $2 Billion dollar settlement arising out of DuPont’s release of “forever chemicals” into soil, wetlands and other areas in New Jersey – and then forgetting to clean up the mess they made. The settlement with DuPont is reportedly the largest environmental settlement ever obtained by a state. “Forever chemicals” – also known as PFAS(referring to per and polyfluoroalkyl substances) are man-made chemicals that are used in an extensive variety of products as they are both water and grease-resistant. The chemicals are linked to litany of health problems, including increased risk of certain cancers(kidney, testicular and breast) liver damage, thyroid issues and reproductive problems(such as decreased fertility, low birthweight and developmental problems). NJ.Com is reporting that one of the sites where DuPont created munitions created such significant contamination in the environment that over 300 homes required filters to prevent toxic chemicals from seeping into their homes. The settlement terms provide that DuPont will spend $875 millions cleaning up the contamination and set aside another $125 million to cover other damages that may arise. Additionally, DuPont will also set p a $1.2 billion funding source and reserve fund of $475 million to ensure that even if the company fails to make payments, or goes bankrupt, public funds will not be used. For a stark introduction into the nature of PFAS, check out Dark Waters, a compelling and criminally underrated movie based on the decades old fight waged by attorney Robert Bilott against DuPont for contaminating West Virginia rural communities.
