FOUR REASONS NOT TO SPECIALIZE IN PUBLIC HEALTH (PH)
John Q. Wong, MD, MSc22 June 2010
BENEFITS OF PUBLIC HEALTH PROGRAMS LIE IN THE FUTURE
Medical care provides quick relief for immediate concerns
Natural response Great effort into
putting out today’s fires
Little into preventing tomorrow’s conflagrations
PH programs You bear the costs
now but the benefits will be reaped on someone else’s watch
Examples Improving road safety Preventing measles Limiting climate
change
BENEFICIARIES OF PH MEASURES ARE GENERALLY UNKNOWN
Medicine deals with identifiable people – patients
Directed at helping you
PH deals with statistical ‘lives’
Directed at improving the health of a group of people Although it’s unclear
whose lives were saved
TYPHOON ONDOY
ONDOY: RESCUE VS. PREVENTION
ABS-CBN P95M cash donations P109M in-kind donations
European Commission P700M in tents,
construction materials, water and sanitation facilties improvements, food, cash-for-work programs, basic agricultural inputs
Individual European countries P600M
Why couldn’t the money have been spent on prevention? Wider and more
extensive sewer systems
De-clogging of sewer systems
Desiltation of rivers Reforestation
PRIVATE MEDICAL CARE VS. PUBLIC HEALTH
St. Luke’s Global City Cost P9.5B 620 patient rooms 500 doctors 1.2:1 patient to
doctor ratio
DOH budget in 2007 P13B 90M Filipinos 63,000 government
doctors 1,428 Filipinos to 1
government doctor
BENEFACTORS, TOO, ARE OFTEN UNKNOWN
Who’s Christiaan Barnard? Heart transplant
surgery 5,000 per year
Who’s Denton Cooley? Coronary artery
bypass graft 800,000 per year
Who’s Maurice Hilleman? Developed more than
40 vaccines Including vaccines for
measles, mumps, hepatitis A and B, meningitis, pneumonia, H. influenza, and rubella
Saves 8,000,000 lives per year
BENEFACTORS, TOO, ARE OFTEN UNKNOWN
Physician providing curative care is more easily identified
People often don’t recognize that they have benefited from a PH measure
People take for granted when They don’t get sick at
work Aren’t poisoned Don’t get run over
SOME PH EFFORTS ENCOUNTER NOT JUST DISINTEREST BUT OUT- AND –OUT OPPOSITION
Medical care is promoted by large special interests Pharmaceutical
companies Private hospitals Insurance companies Medical societies
Some PH measures require societal change Anti-Tobacco Law Alcohol restrictions Gun control Seatbelts Pollution control
Goes against powerful special interests
SUMMARY
Medical practitioners Can see their
patients recover Know their patients
personally Are recipients of the
gratitude and respect of their patients
Are supported by powerful interest groups
Public health practitioners Will not see the fruits
of their labor Don’t know who will
benefit from their work
Receive no credit for their work
Need to go up against special interest groups
WHY SOME OF US ARE IN PUBLIC HEALTH
Public health Produces benefits for many years even
generations Saves lives…millions at at time Not everyone needs recognition Produces fundamental societal change
