CDC Statistics Traumatic Brain Injuries

On August 29, 2011 the Canadian Medical Association published the findings of a multicenter cohort study evaluating the withdrawal of life-sustaining treatment for patients who had suffered a traumatic brain injury. This study is of particular interest because by the nature of the injury  patients cannot make decisions for themselves and generally such decisions in patients in end-of-life care have a variety of comorbidities which make an evaluation of the efficacy of the decisions to withdraw life sustaining care difficult. 

720 patients were evaluated from six different major medical centers. Of the 720, 228 patients did not survive.  160 patients had life sustaining treatment withdrawn in the first three days of hospitalization.

 In approximately 50% of the patients, deaths occurred within the first three days of admittance to the ICU. Most of the deaths were associated with withdrawing life-sustaining care (64%) yet the proportion varied significantly across the six medical centers, from 30.4% to 92.9%

Considering deaths due to withdrawal of life-sustaining care within the first three hospital days, an overall average of 45.6% occurred. However examining the outcomes from the six medical centers, the range of deaths due to withdrawal of life-sustaining care ranged from 22.2% to 59.1%.

According to the “medical teams” and who participated in the care, the reason given for withdrawing life-sustaining care was:

1.     Poor chance of survival. (54.4%).

2.     Prognosis was incompatible with the patient’s wishes. (33.8%)

3.     A poor long-term neurologic prognosis. (28.5%)

These stated justifications are suspect because of the rapidity that decisions to withdraw life-sustaining care were arrived at. As the authors of this study indicate:

 “in this specific population of patients, the decision to withdraw life-sustaining therapy made by patients’ relatives and medical teams is mainly based on prognostic information. Our findings are particularly concerning because many decisions to withdraw life-sustaining therapy were made early in our study: 64% of the patients who died within three days of admission to an ICU had life-sustaining therapy withdrawn. In some instances, this may be too early for accurate neuroprognostication.”

1. “Poor chance of survival. (54.4%)”

     Means: She is probably going to die soon anyway, so let’s not wait and see, waste our time and costs, and extubate now.

This is a, " She is probably going to die soon so let's not wait and see  and waste time and costs and extubate now" type of argument.

Yet, if the patient is going to die “soon” anyway, why not let her die without withdrawing the ventilator - for example. Waiting can only help us have a clearer picture of the degree of the damage and whether or not the patient will show any improvement in her neurologic status?

           2.  “Prognosis was incompatible with the patient’s wishes. (33.8%)”

 This is a “He wouldn’t want to live this way” kind of reasoning. If the physicians for this patient could say to the family, something like: “I can tell you with authority that your son will never be able to have any modicum of awareness, he will never eat on his own, …” If this could be established then the “He wouldn’t want to live this way” reasoning may be an ethically sufficient decision, if in fact the wishes of the patient are clear. However, without such a established prognosis, how can we arrive at a reasonable assessment as to what, exactly, the patient would want. There is little ability to actually assess whether decisions to withdraw life support are genuinely the patient wishes or the wishes of others.

The question that must be posed is whether or not waiting will clarify the prognosis of the patient. If so, then it is indeed premature to withdraw. The fact that, as determined in this study, most patients die after withdrawal from ventilation support, serves to emphasize the need to wait.

“A poor long-term neurologic prognosis. (28.5%)”

This is a: “he probably will survive, but, …” argument. This is the worse excuse of the three listed. It states that: “he probably will survive and if we do not remove life support while he still needs it, someone will probably have to take care of him later. This is tantamount to homicide. We have a non-terminal patient with undetermined future neurologic status who we are going to withdraw life sustaining care to end his life. The total number of patients studied in this cohort was 720. 492 patients did survive, with considerable variability between the participating medical centers.  The authors’ state:

“This raises the concern that differences in mortality between centers may be partly due to variation in physician’s perceptions of long-term prognosis and physicians practice patterns for recommending withdrawal of life-sustaining therapy.”

It is the job of the physicians to treat the patient, not satisfy the needs of the family. Hence, great care must be taken to determine and effectuate the wishes of the patient.

The New Jersey Superior Court–Appellate Division dismissed the appeal in Betancourt v Trinitas finding the appeal moot. The court stressed it's concern over the  “sparse record” presented at the time of  the original hearing in the trial court as well as on appeal and found that the evidence was not “conclusive in several areas necessary to fully adjudicate the substantial issues raised.” This is sometimes referred to as insufficiency of evidence. If the person or entity bringing the case does not provide sufficient evidence the court will dismiss the claim. In this case Tinitas Hospital's request to withdraw the ventilator.

 Ruben Betancourt, 72 years old, was unconscious following the dislodging of a ventilator breathing tube after surgery at Trinitas Medical Center, which resulted in anoxic encephalopathy. He was readmitted to Trinitas in July 2008 with a diagnosis of renal failure. He received dialysis treatments, remained on a ventilator, and feeding tube. The physicians at Trinitas diagnosed Mr. Betancourt as being in a persistent vegetative state and told the family of their intention to stop dialysis and allow him to die.

 “We do not decide the issue but raise it to emphasize why the “thin” and disputed record is so critical to a full analysis.”

The Superior Court in New Jersey (trial court) held a two day hearing and thereafter enjoined the hospital from withdrawing life support without the consent of Betancourt's daughter, Jacqueline, who was appointed his guardian. Mr. Betancourt remained at Trinitas, on the ventilator, receiving dialysis and on a feeding tube until his death in May 2009. The case nevertheless went forward because the attorneys argued that this dilemma is a common occurrence and needs to be clarified by the court.

What this court clarified is that insufficient evidence was presented to consider the issues of withdrawing life-sustaining treatment.  As I pointed out in my previous post: 

            “… the physicians caring for this patient are required to place before the surrogate all medical evidence.

1.        CT and MRI scans,

2.        EEGs,

3.        All respiratory records and any potential to wean him from the ventilator. 

4.        Does he have a tracheostomy?

5.        Are his serious bed sores being tended to or ignored?

6.        What infectious disease is he suffering from?

7.        Is he responding to antibiotics?

8.        To what degree was his brain damaged due to anoxic encephalopathy?

9.        Has the physicians and or hospital discussed the events leading up to the hypoxic event, or hid from it because of concern of liability.

10.      Has all evidence been preserved, provided to the surrogate

11.       Has the ethics committee reviewed the case? If so where is their written report, findings and recommendations?

12.       Have bioethicists and or lawyers participated in conferences with  surrogate?

13.           ETC.

The surrogate cannot perform the job of a surrogate in the dark. This is where detailed records of the conversations and meeting held with the surrogate, family and physicians and reports from the ethics committees are critical to the surrogate’s understanding the issues in order to make a legitimate decision.”

"The uncertainty and lack of true consensus as to Rubin's condition may generate a result that will not only apply to a patient in a non-cognitive, vegetative state, but to a patient who is impaired and in possession of some level of awareness.”

 

Attorneys representing the hospital chose not to bring necessary evidence. Attorneys pick and choose what evidence they wish to disclose as favorable to their client’s position. We can only surmise that the evidence not produced was not favorable. It is often said that bad facts make bad law. A case of great importance to so many must be decided on clear findings of fact.

“…the judge concluded that Ruben was unconscious and in a persistent vegetative state. As it was not necessary to the decision that he reached, the judge made no specific findings, however, concerning Rubin's ability to perceive pain or react to his surroundings. The uncertainty and lack of true consensus as to Rubin's condition may generate a result that will not only apply to a patient in a non-cognitive, vegetative state, but to a patient who is impaired and in possession of some level of awareness.”

The absence in evidence of the usual procedures when an impasse is reached between physicians and patients is to call for help – from consulting bioethicists and ethics committees who will bring to bear physicians of various specialties, lawyers, lay people and clergy from the community. The surrogate decision maker would then have the benefit of views - and the reasons therefore – to consider facts outside any adversarial proceeding.

There was no indication that this review or participation of the bioethics consultant, or even be ethics committee, was involved in the attempt to resolve the dispute between the patient's surrogate and be patient's physician.

Thus, the attorneys representing the hospital did not give to the trial court sufficient facts to make a decision to the grant the withholding of life-sustaining treatment to Mr. Betancourt. .  As the court said in the opinion in this case: “We do not decide the issue but raise it to emphasize why the “thin” and disputed record is so critical to a full analysis.”

HEALTH AND SAFETY CODE CHAPTER 166.039.

PROCEDURE WHEN PERSON HAS NOT EXECUTED OR ISSUED A DIRECTIVE AND IS INCOMPETENT OR INCAPABLE OF COMMUNICATION

For the most vulnerable patients, without friends or family, life for some medical patients in Texas, is cheap.  On vague and specious grounds and without proper oversight or transparency, physicians may withdraw life sustaining treatment from a patient, even if the patient is conscious, talking, and aware of his or her surroundings. This statute allows this to occur if a physician treating the patient concludes that the patient will die within six months and there is no advance health directive to the contrary.

There is a fundamental liberty interest which permits a patient to refuse life-sustaining treatment. There is also a fundamental constitutional right, which each person has, to his or her life.  This right is protected by the due process clause. Yet, Texas law makes a presumption that leads to an unjustified decision to withdraw life sustaining treatment. The statute declares that merely because a patient has not filled out or written an advance health directive does not mean they don’t want to die.  So, under Texas law, a conscious, but incompetent patient will be allowed to die if a physician, with “reasonable” medical judgment decodes that the patient will die within six months. “Reasonable” medical judgment is a low standard for the death of a patient. It does not require a "probability of death" with 6 months – only a reasonable and unchecked judgment. Moreover, the available safeguards which would require the review by a hospital ethics committee, or a court of law, is not a hurdle that is required to be cleared before removing the patient from life sustaining care. As long as there is no advanced health directive, and no family or friend to object, a physician can order the cessation of life support, if a non-treating physician or a member of the ethics committee agrees. Nor is there any effort or requirement of due diligence that must be made to locate friends or family.

In looking at this statutory scheme we should keep in mind the words of another Texan:

           "You do not examine legislation in the light of the benefits it will convey if properly administered,but in the light of the wrongs it would do and the harms it would cause if improperly administered."
Lyndon B. Johnson

A conscious competent patient (with a terminal illness) who asks for help to end suffering may not be helped by their physician to end her life. This is considered physician-assisted suicide and is prohibited by law.  However, under Texas law, a conscious patient who cannot decide for him or herself, and therefore needs the utmost protection, can have life-sustaining treatment independently halted by their physician and die without violating the patient’s constitutionally protected right to life. To overcome a fundamental constitutional right a full and comprehensive review of all relevant facts, opinions, motivation, bias, undue influence, is guaranteed by the due process clause of the fourteenth amendment. Why were these safeguards unconstitutionally cast aside by the Texas legislature?

It is clear that the right of a patient to withhold or withdraw from any treatment, including life sustaining treatment, is predicated on a legal tradition protecting the autonomous decision to refuse unwanted medical treatment. However, we must be careful to make the distinction that the right to refuse treatment is the patient’s right, not the right of a physician or hospital, or legislature. A presumption that the patient would choose death rather than life seems to be founded on a legislatively created principle that people, without known friends or family, rights can be disregarded and that the economic interest of the state is sufficient to overcome life. The Texas law that permits a casual and unregulated state imposed medical decision making scheme is unconstitutional.

In most circumstances, there are no specific statistical data on death from a specific disease within six months.  When there are one or more studies, they are based upon information gathered from different medical communities with different demographics . The data will vary based on the age, type, and extent of disease and with different accompanying disease processes.  Nevertheless, this statue presumes that a physician, irrespective of her specialty, is aware of all studies, and that all studies are based on relevant and sound epidemiological principles, and sufficiently powered biostatistical results.

In this way, patients are left to the creative medical imaginations and empirical and anecdotal experience. which will vary between physicians, that will determine a decision of life or death. 

Review by the entire ethics committee, with a written explanation, must be legally mandated. There is, at present, a Bill in the Texas Legislature to amend  this statute, Section 166.039. A requirement for mandatory ethics committee review should be included.

The Texas statute’s 6-month standard is illusory and prone to ethnic, racial, socioeconomic status and age bias. This, more often then not, will be a member of a minority group, whose family and/or friends cannot be located, or the patient is simply alone. So, the statute targets the most vulnerable patients who need the highest level of protection.

Advance Health Directive:

Patient has an advanced health directive, witnessed, notarized and in the format of a legal document done by his attorney, rejecting treatment if he has a terminal condition with the probability of death within a few months; and/or an irreversible condition requiring artificial life support. Patient’s daughter is designated as surrogate. The document is notarized.
This 84 year old man is admitted for pneumonia; dementia; depression; anemia; malnutrition; renal failure, and hypernaturemia.

History: Dysphasia, anorexia, ataxia, poor intake, altered level of consciousness, restless, hypotensive, shortness of breath, bilateral rales. He is unable to give any history himself.

Admitting: Diagnosis: Acute pneumonia on top of interstitial lung disease and bronchiectasis.
The patient is intubated and noted to have renal failure, thrombocytopenia, leukocytosis, anemia, and deteriorating mental condition.

Patient’s daughter advises that her father never wanted to be maintained on artificial life support. Options are discussed with daughter, who requests that a do not resuscitate order be instituted.
Daughter advises bioethics consultant that she is waiting to hear from doctors regarding their opinion as to whether or not the pulmonary condition is irreversible, as described in the advance health directive. If so she wants to refuse continued artificial ventilation. Pending the receipt of that information she requests that no tracheostomy be performed. She insists that the patient not be sent to a skilled nursing facility.

Nevertheless, it is recommended, and the daughter consents to a tracheostomy. Daughter has not, however, been told any opinion as to irreversibility of respiratory failure. Attempt at weaning is ordered and patient is extubated. He deteriorates and is reintubated the same day. Pulmonologist, without consulting patient's daughter, writes order that patient be transferred to a skilled nursing facility.

Daughter is advised by nurse about the transfer order and refuses transfer. She reiterates that her father would not want to live in a skilled nursing facility on artificial life support. Under these circumstances he would reject continued artificial ventilation. Daughter says she does not want futile care. Patient’s daughter, and bioethics consult request a meeting with pulmonologist. There is no response from pulmonologist, one-way or the other.

The pulmonologist ceases to participate in case without any discussion with daughter. Daughter requests and signs withdrawal of artificial ventilation form. Three days later the daughter is notified that her father has been extubated and transferred to a skilled nursing facility. She, however, is unable to locate her father at that facility and is told that her father "never arrived." She calls the hospital and is told that he is no longer a patient at that hospital. She thereafter discovers, through the nursing administration office, that her father has died and that his body has been in the hospital's morgue for 3 days.

Comments:

1.    Physicians as well as patients and family often have difficulty withdrawing life-sustaining treatment. The daughter never received an answer as to the probability of death or of the irreversibility of the patient’s condition - the criteria set forth in the advance health directive. Her decisions were not informed.She felt abandoned by the pulmonologist who seemed to "just disappear."

2.    There is no obligation for a physician to treat a patient in a way that is contrary to the physician’s conscience. A physician does have the obligation, however, to inform a patient, or if necessary a surrogate decision maker, as to the diagnosis and prognosis, including risks of treatment and of non treatment. Before signing off the case the pulmonologist, should have and easily could have advised the daughter that he was withdrawing from the case and discuss options, which should have included arranging for a new pulmonologist on the case.

3.    There is reluctance on the part of many physicians to discuss end of life care and options. An Institute of Medicine study on improving care at the end of life found that there is often:
a) Overuse of care that is inconsistent with patient preferences and prognosis;
b) Underuse of care to treat symptoms;
             c) Untimely referral to hospice;
             d) Poor palliative care;
             e) Poor communication regarding prognosis and treatment preferences.

In a cohort study of 1573 patients, prolonged ventilation was not generally discussed:
         12% of patients discussed preferences with their physicians,
         20% said that they wanted it,
         80% said that they did not want it.
Annals of Internal Medicine: 1 July 1997 | Volume 127 Issue 1 | Pages 1-12

4.    After withdrawal or withholding artificial life support, the need for palliative care must be conscientiously provided to patient and/or surrogate decision makers. Responsibility for patient care does not end with a decision to withdraw artificial life support.

5.    Support for family members should continue. This case illustrates that physicians can lose interest in a patient after a decision to withdraw or withhold life-sustaining treatment.  In this instance this may have contributed to the failure to maintain a line of communication with this patient’s daughter, including advising her of her father’s death.
