I recently finished reading a great book by William Bynum called The History of Medicine: A Very Short Introduction. The book does just what it says: provides a great introduction to the history of medicine.  It is concise and interesting throughout.  The contents are divided into six chapters:

  • Medicine at the bedside
  • Medicine in the library
  • Medicine in the hospital
  • Medicine in the community
  • Medicine in the laboratory
  • Medicine in the modern world.

This chart explains the differences between the first five kinds of medicine.

There are many interesting nuggets of information from this book and picking out a few is difficult.  I’ll settle for two which discuss the unintended consequences of the invention of anesthesia and antibiotics:

Giving surgeons more time to operate made conserving tissues easier, but the longer exposure of the open wounds to the air also increased the possibility of post-operative infection.  Consequently, anaesthesia enlarged the range of operations surgeons could perform, but not necessarily the changes of a patient’s surviving the ordeal.

The causative agents of malaria, tuberculosis, and HIV have all developed resistance to many of their conventional treatments, complicating these major world diseases.  The hospital has not ’caused’ this phenomenon; human agency has.  But drug-resistant pathogens are now so common that modern hospitals sometimes lose their desired epithet, as ‘houses of healing,’ and revert to that old one, ‘gateways to death.’

Here is Amazon’s summary of the book:

Taking a thematic rather than strictly chronological approach, W.F. Bynum, explores the key turning points in the history of Western medicine-such as the first surgical procedures, the advent of hospitals, the introduction of anesthesia, X-Rays, vaccinations, and many other innovations, as well as the rise of experimental medicine. The book also explores Western medicine’s encounters with Chinese and Indian medicine, as well as nontraditional treatments such as homeopathy, chiropractic, and other alternative medicines.

In 2009, President Barack Obama addressed the nation calling for healthcare reform.  In 1974, President Richard Nixon also addressed the nation calling for healthcare reform.  Let us analyze Nixon’s speech and compare it to Obama’s.

  • Today the need [for reform] is even more pressing because of the higher costs of medical care.”  Obama echoes this sentiment. 
  • …the 25 million Americans who remain uninsured.”  Nixon hoped to expand coverage for the 25 million Americans who, in 1974 who did not have health insurance.  He planned to do this using with the creation of “Assisted Health Insurance, covering low-income persons.”  In 2009, there are 46 million uninsured Americans.  Obama also proposes using tax credits to help poor and middle class individuals afford private insurance.  Obama also proposes a public option.
  • Americans who do carry health insurance often lack coverage which is balanced, comprehensive and fully protective.”  Health insurance was originally created as protection against serious illnesses and hospital stays.  Routine physician visits were not covered.  This often meant that check-up and preventive care was not covered and Nixon wanted to expand the scope of insurance coverage.  In the present day, most individuals who have insurance have relatively comprehensive health insurance.  In fact, as a reaction to the expanding scope of present day health insurance, Republicans support HSAs which use high deductibles to transfer more of the cost of care towards the individual patient.
  • Comprehensive Health Insurance Plan (CHIP).  This was Nixon’s solution to the problem that many individuals who had insurance had only partial insurance.  It basically expands the scope of insurance coverage. In the present day, most individuals who do have insurance have relatively comprehensive coverage.
  • Third, it builds on the strength and diversity of our existing public and private systems of health financing and harmonizes them into an overall system.”  Nixon’s CHIP plan aims to provide subsidies for health insurance and aims to reform health care, but will not overhaul the system (à la a single payer system or the elimination of Medicare in exchange for all private insurance).  Obama’s currently proposes reforms to the current system that also builds on the existing healthcare infrastructure.
  • Fourth, it uses public funds only where needed and requires no new Federal taxes.”  Nixon claims that his plan will not use any new taxes.  Obama did not claim he would not raise taxes, but did assert that “I will not sign a plan that adds one dime to our deficits.”  However, the government’s spending on health care as a share of GDP has accelerated over time.  This was true in Nixon’s time, is true now, and most expert believe it will continue into the future.
  • Sixth, it encourages more effective use of our health care resources.”  Obama wants to “eliminate is the hundreds of billions of dollars in waste and fraud” as well as “create an independent commission of doctors and medical experts charged with identifying more waste in the years ahead.”  More effective use of health care resources was, is and will continue to be a laudable goal; actually realizing these efficiency gains in practice, however, is more difficult.
  • No family would ever have annual out-of-pocket expenses for covered health services in excess of $1,500, and low-income families would face substantially smaller expenses.”  Nixon planned a cap on patient annual out-of-pocket costs.  Currently, Nixon’s proposal has become commonplace.  Most group health insurance plans offer an out-of-pocket cap as does Medicare and Medicaid.  However, for non-group health insurance, these caps are often not available.  Obama proposed that health insurance companies “…will no longer be able to place some arbitrary cap on the amount of coverage you can receive in a given year or a lifetime.”
  • Medicare, however, does not cover outpatient drugs, nor does it limit total out-of-pocket costs.”  Nixon believed that Medicare should cover drug costs and limit out-of-pocket costs.  Medicare does limit out-of-pocket costs and, with the creation of Medicare Part D, most prescription drug costs are covered for seniors. 
  • COST: “the total new costs…would be about $6.9 billion.”  Obama’s plan would cost “$900 billion over ten years.” 
  • Nixon wanted to “increase the supply of physicians.”  Nixon believed that increasing the supply of physicians will drive down costs as competition increases.  With patient paying less and less money out of pocket, this may no longer hold.  If supplier-induced demand exists, an increase in the supply of physicians will increase demand and costs and not necessarily decrease prices.  Obama did not discuss physician shortages in his speech.  
  • On December 29, 1973, I signed into law legislation designed to stimulate, through Federal aid, the establishment of prepaid comprehensive care organizations.”  HMOs now control a significant portion of the health insurance market.
  • I also contemplate in my proposal a provision that would place health services provided under CHIP under the review of Professional Standards Review Organizations. These PSRO’s would be charged with maintaining high standards of care and reducing needless hospitalization.“ This is similar to Obama’s “independent commission of doctors and medical experts charged with identifying more waste in the years ahead.”

A paper by Alexander S. Preker and April Harding at the World Bank analyze the roles of the public and private sector in health care.  One of the more interesting portions discusses medical care financing using some examples from ancient history.

Ideological views on the roles of the state and the private sector belong to a long list of false antitheses in the field of medicine and health care. Since the beginning of written history, the pendulum has swung back and forth between minimalist and heavy-handed state involvement in the health sector.

During antiquity, people used home remedies and private healers when they were ill. Yet, as early as the second millennium B.C., the papyri give fascinating evidence that Imhotep, archetypal physician, priest, and court official in ancient Egypt, introduced a system of publicly provided health care with healers who were paid by the community.

This early experiment in organized health care did not survive the test of time. The Code of Hammurabi (1792–50 B.C.) laid down a system of direct fee-for-service payment, based on the nature of services rendered and the patient’s ability to pay. For the next three thousand years, the state’s involvement in health care revolved mainly around enforcing the rules of compensation for personal injury and protection of the self-governing medical guild.

At best, financing, organization, and provision of health care was limited to the royal courts of kings, emperors, and other nobility who might have a physician for their personal use and for their troops at the time of battle. The masses got by with local healers, midwives, natural remedies, apothecaries, and quacks.”
