Thad Pope has a useful post on this subject. There are direct medical costs (estimated at $2,700/day (Ottawa study) to $4,000/day (UCLA study)), but equally if not more concerning "may be (a) the opportunity cost when other patients are denied ICU care, (b) moral distress of the nursing staff, and (c) suffering inflicted on the patient."
None of this seems to matter to the legislators in Texas who try, every legislative session, to gut the provisions of the Texas Advance Directives Act that were added in 1999 to deal with disputes over medically inappropriate treatment. The provisions are at Tex. Health & Safety Code § 166.046. The purpose of the law was to provide a nonjudicial mechanism for resolving these disputes. The key provision is in subsection (d), which -- after reasonable efforts over a 10-day period to find a provider willing to provide the treatment requested by the surrogate decision-maker fail to identify a provider willing to accept transfer of the patient -- permits the disputed treatment to be withheld or withdrawn.
The objectors in the legislature want to replace that 10-day process with a provision that requires the health care providers to "treat until transfer." This benign-sounding idea would mean that, in the vast majority of cases in which no transferee provider can be found, medically inappropriate treatment must be provided until death occurs, which may be months or even years later. A current example is the Tinslee Lewis case in Fort Worth, which has been in litigation for over two years. According to a motion filed by defendant Cook Children's Hospital,
a review of Tinslee’s case was initiated by third-party administrator Aetna’s Special Investigative Unit, which has requested all of Tinslee’s records. The Special Investigative Unit’s mandate under Medicaid regulations is to investigate “waste, abuse, and fraud,” the motion says.
“In Cook Children’s experience, such reviews are often precursors to efforts to deny payment or even claw back funds previously paid,” the motion said.
