The thing is, CPR is ineffective at treating the underlying condition that is bringing about the patient's death. And even as a stop-gap to allow treatments to take effect, it mostly works in a small cohort of patients:
CPR can save lives when patients are relatively healthy, and when the cause of their death is reversible or unclear. Damar Hamlin, the Buffalo Bills player whose heart stopped during a nationally televised game in January, typifies the person for whom CPR was invented: young and fit, and the victim of a sudden, treatable injury rather than a progressive disease. Still, less than ten percent of people who receive CPR outside a hospital survive. Inside hospitals, where CPR begins quickly, the odds are slightly better, but only for those who aren’t in the last stages of life. A mere two per cent of adults over sixty-seven with severe chronic disease, including cancer, are alive six months after CPR, and they often deal with pain, physical debility, and post-traumatic stress disorder. Reversing a death is not the same as restoring a life.
And yet doctors, including a younger version of the author, often give families the choice of performing CPR or not without offering the grim statistical chance of failure, giving the impression that they are choosing between life or death. Families and physicians alike are traumatized in these situations because the truth is not easy to discuss.
Texas is one of the few states in the country that offers legal protection for physicians who resist requests for medically inappropriate treatment (Ch. 166, Tx. Health & Safety Code). It was amended in 2017 to add Subchapter E, which may fairly be characterized as hostile to do-not-resuscitate (DNR) orders. The unfortunate result has been to sow confusion and doubt about when a hospital DNR order may be written and, once written, when it may or may not be followed. The need for such a law was dubious at the time, and although amendments have provided some clarity, Subchapter E stands as a prime example of the unwisdom of legislatures prescribing standards of care.
