“Parachute use to prevent death and major trauma when jumping from aircraft: randomized controlled trial
BMJ 2018; 363
“”Ah, but the method of madness matters! The non-participating passengers flew at 800 km/hr at an altitude of 9,146 m, but the trial participants jumped a whopping 0.6 meter (2 feet) from a plane traveling at an incredible 0 km/hr. The authors point out their trial’s glaring limitation — an inability to generalize to higher altitude jumps — and use it make a point that health journalists would be wise to remember:
“When beliefs regarding the effectiveness of an intervention exist in the community, randomized trials might selectively enroll individuals with a lower perceived likelihood of benefit, thus diminishing the applicability of the results to clinical practice.
This study was conducted in response to a Christmas, 2003 BMJ article decrying the lack of RCT (Random Controlled Trials) for the efficacy of parachutes. As the authors of this article point out, even RCT’s have their limits.
As one review explains,
Put plainly, if most people already think an intervention works, then an RCT may end up with enough bias in its design that the conclusion ends up clinically meaningless. Sometimes, an RCT is truly unethical, and other times an RCT really might be needed to test an intervention taken for granted. Health journalists should scrutinize an RCT’s methods closely.

Cook Children’s Statement Regarding Patient Tinslee Lewis Fort Worth, Texas (November 10, 2019) –
Tinslee Lewis is a beautiful baby who has captured the hearts of many at Cook Children’s since her premature birth nine months ago. She was born with a rare heart defect called an Ebstein’s anomaly and has undergone several complex surgeries at Cook Children’s in an effort to improve her heart function. Further complicating matters, she also suffers from chronic lung disease and severe chronic pulmonary hypertension. Due to these complications, she has spent her entire life hospitalized in Cook Children’s intensive care unit. She has required artificial respiratory support throughout that time, and has been consistently on a ventilator since July.
In the last several months, it’s become apparent her health will never improve. Despite our best efforts, her condition is irreversible, meaning it will never be cured or eliminated. Without life-sustaining treatment, her condition is fatal. But more importantly, her physicians believe she is suffering.
To maintain the delicate balance necessary to sustain Tinslee’s life, and to prevent her from pulling out the lines that are connected to the ventilator, doctors have had to keep her constantly paralyzed and sedated. While Tinslee may sometimes appear alert and moving, her movements are the result of being weaned off of the paralyzing drugs. We believe Tinslee is reacting in pain when she’s not sedated and paralyzed.
Cook Children’s has made heroic efforts to treat Tinslee’s condition, all while being very transparent with her family regarding her poor prognosis. Despite those extraordinary efforts, Tinslee’s condition has not improved. At the request of Tinslee’s family, we have reached out to nearly 20 facilities across the country to see if any would be willing to accept Tinslee as a patient. Some of the facilities include:
Texas Children’s Children’s Memorial Hermann Hospital Dell Children’s Dallas Children’s Medical City Dallas Children’s Medical Center Oklahoma City Children’s Hospital of Atlanta St. Louis Children’s Children’s Hospital of Philadelphia Johns Hopkins Methodist Hospital San Antonio University Hospital San Antonio Boston Children’s Children’s Hospital of Los Angeles Arkansas Children’s C.S. Mott Children’s Michigan LeBonheur Children’s Memphis Rady Children’s Children’s Hospital San Antonio CHRISTUS
All have said our assessment is correct and they feel there is nothing more they can provide to help improve this precious child’s life.
A team of Cook Children’s doctors nurses and staff have given their all to help Tinslee. While, we believe every child’s life is sacred, we also believe that no child should be sentenced to a life of pain. Removing this beautiful child from mechanical ventilation is a gutwrenching decision for Cook Children’s physicians and staff, however we feel it is in her best interest to free her from artificial, medical intervention and suffering.

“In the last several months, it’s become apparent her health will never improve,” King said in a statement via email. “Despite our best efforts, her condition is irreversible, meaning it will never be cured or eliminated.

“While we believe every child’s life is sacred, we also believe that no child should be sentenced to a life of pain,” said Winifred King, assistant vice president of public relations for Cook Children’s Health Care System, in a statement. “Removing this beautiful child from mechanical ventilation is a gut-wrenching decision for Cook Children’s physicians and staff; however, we feel it is in her best interest to free her from artificial, medical intervention and suffering.”
“Although no reason is required by law, in every case I know of the doctor has made it clear that the requested treatment is causing suffering and/or actual harm and violates the First Principle: “Cure when possible, but first, do no harm.”’
