I am at a medical school which has begun a new curriculum that integrates the basic and clinical sciences in a system-based approach. Currently, we are studying the cardiovascular system, diseases, and treatments. Fully integrated into the curriculum are topics including behavior, psychology, sociology, and others that attempt to give us background on the patient's biopsychosocial status and factors that might affected the medical care provided. For example, in this block we have had lectures on medical adherence, risk factors for cardiovascular disease, and others. In addition, we take a 2-year long course on the foundations of patient care, including the doctor-patient relationship, professionalism, physical exam skills, and ethics.
Here are your questions and my responses:
1. all doctors (not surgeons) do is push pills to patients. basically, taking a history, exams, etc, is all done to figure out which medicine to prescribe.
First of all, doctors come in many varieties--there are primary care docs and there are specialists in a variety of fields. Some fields tend to be medical, some tend to be surgical. Others are a combination of both. In addition, some doctors choose to do medical research as part of their careers, and thus arrange or participate in clinical trials, conduct basic lab research, etc. Other doctors study public health or participate in hospital administration. What I'm trying to say is that medicine is a big, complex world with many players, who all contribute to providing patient care. True, the H&P is the bread and butter of medicine, but a computer is simply NOT capable of doing the job. If my computer started palpating my abdomen, I'd be a little concerned.
Also, medical therapy is not always warranted in certain situations. For example, in mild and moderate hypertension, you would generally start out by attempting to get the patient to make lifestyle changes (i.e. quitting smoking, less fat/cholesterol in diet, exercise, etc) before heading to medical therapy. Whenever possible, lifestyle changes and/or other preventive measures are preferred. When there is a need to medicate a patient, the drugs are chosen on a rational basis, which take into account a variety of factors to predict response to therapy. But like a person above noted, individuals differ in their response and side effects. Thus, if a patient experiences a large number and severity of side effects on a particular drug, you might want to switch medications and try something that will be better tolerated. To the outside observer (and often to the patient) this might seem like the physician is just playing a guessing game. However, there should be (and usually is) some rationale behind given therapy. Surgical procedures are considered under specific criteria, having to do with the efficacy of treatment, possible complications, etc. To consider a therapy (medical or surgical), there must be INDICATIONS for that therapy. Sometimes patients require both medical and surgical intervention (i.e. heart valve replacement with prophylactic antibiotic therapy in cases of valvular disease). The point is that doctors do a large degree of critical thinking in terms of managing patient care that a simply algorithim cannot replicate.
2. drug companies throw money at doctors, trying to sway them to use their drug. why is it that college athletes get punished for getting a few gifts here and there, but it's ok for doctors to get free tickets to basketball games paid by drug companies?
It is true that drug company advertising has an influence on the types of prescriptions doctors write. The goal as a physician is to not be swayed by free lunches, pens, pads, etc and to remain as objective as possible, critically evaluating the data.
3. doctors don't really know if a medicine will work. it's like "here take this, and tell me how you feel later. if something bad happens, i'll give you a different pill"
Answered above.
4. when all the drugs don't work, the doctors just send patients to surgeons to do the real work.
Medical doctors and surgeons are both essential components of the medical team and both contribute the management of patients. To say that one or the other "does the real work" is incorrect.
Medicine, with all of its problems, remains one of the most noble professions. Physicians are given a special and sacred responsibility to care for the health of those who are sick and to prevent illness. Doctors have a role as health educators, as well as source of compassion and empathy. In addition, many of the discoveries that will provide new preventions and therapies will come from physician-scientists. Thus, whether you believe medicine is a "shady" profession or not, doctors certainly have a vital role in society.
