Making Informed Medical Decisions
Introduction
Decisions
about medical care can be very difficult - and literally, matters of life
and death. Feeling comfortable that a particular decision is the best
decision for you (or for a person you love) depends a great deal on the
process of understanding the choices. Knowing the steps in the medical
decision process is often helpful in reaching a decision that "feels
right." In this essay, we describe the 'basics' of making medical
decisions and offer several suggestions that we hope will improve your
confidence in the decision process.
The
"Parts" of a Medical Decision
A remarkable amount of information is gathered (and created) in the medical
decision process. Some information comes from the patient, some from the
physician, and quite a bit is created new in the patient testing process.
Medical information includes data about the following:
- Past
Medical History
(including prior surgeries, previous illness, and personal health habits)
- Current
Health Status
- Medications
- Other
current health conditions, such as chronic illness involving other
organ systems
- Current
physical condition, such as age, proper weight, nutrition, and other
factors
- Cardiovascular
fitness (physical "reserve" to withstand stress)
- Life
expectancy
- Other
measurements and attibutes of current health status
- Personal
Values
- Religious
convictions that influence the care process
- Advance
directives (including "Living Wills"), such as "Do
Not Resuscitate" orders, and willingness to be an organ donor.
- Medical
Assessment
- Current
History and Physical Examinations
- Laboratory
Blood Testing, as needed
- Radiology
(Imaging) Examinations, as needed
- Other
Special Testing (Heart and Pulmonary Functions, etc, as needed)
- Specialty
Physician Consultations, as needed
- Medical
Knowledge
about the natural history of the Condition(s) being considered, including
the fate of other patients with similar conditions and treatment options.
The
"Sequence" of Medical Decisions
Although
it may seem obvious, the medical decision process does not begin until
the patient gives permission to begin. This means that the patient agrees
that he or she has a medical condition (or change in health status) about
which a decision (that is, a treatment) is desired.
Unfortunately,
it is a not unusual to have a period of "denial" - when the
patient (or another significant person in the patient's life) refuses
to deal directly with the problem. (Occasionally, "denial" can
result in delays which significantly interfere in the diagnostic and treatment
process! Although the causes for denial can vary from person to person,
it is often rooted in a fear of the unknown; once the person in denial
decides that knowing more is probably better than knowing less, the process
continues).
- Step
1:
Statement of the Presenting Complaint (or physical finding)
- Step
2:
Initial Medical Assessment (history, physical examination and pertinent
special tests)
- Step
3:
Identification of Normal and Abnormal Findings (up to this point in
the process)
- Step
4:
Creation of the Initial List of possible Medical Conditions (i.e. Differential
Diagnoses)
- Step
5:
More testing, as needed, to narrow the list of possibilities and/or
confirm the most likely condition. This may include invasive testing
(like arteriograms, or tissue biopsies) or opinions from other medical
specialists.
- Step
6:
Treatment Intervention (for example: medication, angioplasty, surgery)
- Step
7:
Collection of pertinent information to assess the effectiveness of the
selected treatment.
Discussion
The sequence of the medical decision process repeats itself over and over
until the presenting problem (abnormal condition) is resolved, or the
patient dies (either from the condition undergoing treatment or for any
other reason).
Early
in the process, the decisions are focused on confirming the accuracy of
the "working" diagnosis - a technical description of the problem.
Once the diagnosis is certain (confirmed), the decision process narrows
to the treatment options - although good physicians stay perpetually alert
to any information that "doesn't fit the pattern."
The
medical decision process is not perfect. Experts often disagree about
the significance of particular findings, or may vary in their preference
(experience) for specific treatment options. Expected and unexpected complications
(and side effects) occur - nausea & vomiting from chemotherapy, or
an allergy to a drug (which can be life threatening, by themselves).
Understanding
the "Benefits versus the Risks" is a crucial step in the decision
to make an intervention at all. "First of all, do no harm" is
an expression that dates back to the Greeks (Hippocrates), and acknowleges
that sometimes the treatment can become worse than the problem. Occasionally,
the expression "Benefit vs Cost" is used nearly interchangeably
with "Benefit vs Risk." Cost may be understood in broader terms
than just dollars: the number of hours of nursing care, emotional suffering,
disability from working, etc. In the decision process, each interventional
option is considered with respect to its benefit versus risk/cost for
this patient (when compared to similar patients in the past who selected
different treatment options).
One
difficulty in the medical decision process can be getting lost in statistics.
Physicians have studied nearly everything about medical care, but not
all researchers get the same results. Statistics are often used to try
to "compare apples with apples." For example, suppose that you
are told that the best drug for strep throat is penicillin -- which is
95% effective in your geographical area for the strain of Strep you have.
You are also told that about 1 dose in 100,000 doses of penicillin is
fatal, due to drug allergy, whether the recipient is known to be allergic
or not (not a very common complication). But, if you are the one to whom
that happens, you will still be 100% dead! At some point in nearly
every medical decision, you "take your chances" and hope for
the best. Obviously, everything is done to reduce the risk/cost, but the
possibility of some risk is never completely eliminated.
The
Time Factor
Some medical conditions, like abrupt unconsciousness or a serious heart
attack, alter the medical decision process significantly. There is no
longer the luxury of time to make a comprehensive decision that collects
and considers all of the desired information. Rather a decision must be
made on the spot, with the available information, hoping for the best.
Under such conditions, many steps in the process described above may be
left out due to the urgent effort to save the patient's life. (For example,
brain damage occurs in 4 minutes when blood flow to the head is interrupted
- in a cardiac arrest, therefore, asking questions is irrelevant, when
cardiopulmonary resuscitation (CPR) is required.)
What
YOU can do to be well-informed
- Learn
how the medical decision process works:
- Be
certain you understand where you are in the process; early on, the
decisions usually involve reaching the correct diagnosis; late in
the process, decisions involved stopping or changing particular
treatments.
- Making
written notes is an excellent idea, especially if you have trouble
remembering complicated material. Ask the physician or nurse to
spell the key technical names
- Be
sure you understand the possible complications, and how often they
occur
- Ask
what the cost will be, whether that is a factor in the decision
or not
- Ask
what you should be alert to notice as the process proceeds
- Be
alert to the unexpected, and ask about what you don't understand.
It may save your life.
- Learn
the functions of the normal and abnormal organs involved in the condition
you are studying
- Promote
good health habits and a balanced life style
- Learn
about the condition (diagnosis) and its treatment from credible references
- Community
library
- Internet
- be careful to seek information at your level of comprehension
(the Internet has everything) and beware of sites which are advertising
specific products (they are not always honest and objective). Use
your common sense, and whenever possible use website links recommended
by respected health experts, such as those found on this website.
- Be
cautious about testimonials and anecdotes - reported by friends,
newspapers, and advertisers.
- Ask
for help !!
- Physical
- stick to the prescribed treatment, once the decision has been
made.
- Emotional
- consider participating in a support group with others affected
by this problem or seeking the support of trusted friends
- Spiritual
- seeking help within your church, or research writers/speakers
who have a spiritual message
- Stay
focused on what you CAN do, and don't dwell on what you CANNOT do.
