Throughout history, doctor-patient
relationships have been acknowledged as having an important therapeutic
effect, irrespective of any prescribed drug or treatment.
In an era of brief doctor visits and high-tech medicine,
it may be the development of warmth and empathy between
doctors and their patients that makes the difference in care.
The study found that doctors who showed empathy and
acknowledged their patients' fears and anxieties were more
effective than doctors who kept patients at an emotional arm's
length.
Researchers grouped 25 medical, psychological and
sociological studies of care delivery by the doctor's style of interaction
with patients. In "cognitive" care, the doctor tried to influence
or convince a patient about an illness or treatment, while in "emotional"
care, the consultation was deemed warm and empathic and the doctor tried
to relieve patients' anxiety and fears.
Although none of the studies looked exclusively at
emotional care, four evaluated both cognitive and emotional care. Three
of these studies showed that support and reassurance enhanced
health outcomes as measured by blood pressure readings and
patient reports of pain.
In a healthcare consultation, doctors can offer social
support to patients, give them a safe space to open up and discuss their
problems and reassure them with a diagnosis or a treatment, thereby relaxing
them and lowering their anxiety. l of these ingredients have been linked
with immune function.
The study should be a
wake-up call to doctors.
The effects of the relationship on the course of illness
indicates that the context of care influences patients' well-being.
As long ago as 400 BC, Hippocrates wrote of how "the
patient, though conscious that his condition is perilous, may recover
his health simply through his contentment
with the goodness of the physician".
Author (Lancet 1955; 1: 683-88) later added that what
mattered was "not only the medicine . . . or the pills . . . but
the way the doctor gave them to the patient -- in fact the whole atmosphere
in which the drug was given.
A review (JAMA 1994; 271: 1609-14) on pain and the
placebo effect concluded that
"The quality of the
interaction between physician and patient can be extremely influential
in patient outcomes,
and . . . patient and provider expectations may be
more important than specific treatment".
Effects originating from health-care interactions
include factors common to all medical, alternative, and psychological
therapies -- eg, attention, bedside manner, empathy, positive regard, compassion,
hope, and enthusiasm.
When threatened by signs and symptoms of illness,
individuals respond with cognitive and emotional reactions. For example,
sudden pain may cause an individual to feel anxious and to try to make
sense of the situation by thinking about what it might be, what caused
it, whether it is curable, what the consequences could be, and how long
these symptoms might last.
The researchers found that practitioners who attempted
to form a warm and friendly relationship with their patients, and reassured
them that they would soon be better, were found to be more
effective than practitioners who kept their consultations impersonal,
formal, or uncertain.
Giving different diagnoses to patients presenting
with similar symptoms had little or no effect, perhaps because the diagnoses
given were for relatively mild conditions. For more serious illnesses,
effects are possibly stronger, but ethical and practical reasons would
obviously prevent researchers from doing such studies.
Vast amounts of energy and resources have been spent
to advance diagnostic tools, and pharmacological and surgical treatment.
The lack of attention to the more humane aspects of
care, alongside increased specialization and shortened consultation
time affects the patient-practitioner relationship.
Bedside manners, the warmth of the doctor-patient
relationship, and other features of good doctoring contribute to the outcome
of medical care, yet they have been treated contemptuously by the biomedical
community as factors that produce placebo (or context, or non-specific)
effects that should not work even if they do. The most impressive examples
of the potential clinical relevance of context of care have been found
in relation to the survival of cancer.
