there are a bunch of threads on this, but if you want some general topics:
medicare as a government price setter
medicare and its financial sustainability (see baby boomers)
medicare as a massive government entitlement
anything else related to medicare
managed care and physician autonomy/reimbursement
pharmaceutical drugs - rising costs, new medicare drug benefit, research and development, advertising and marketing (ethical considerations)
specialty providers (hospitals, surgery centers, anything with physician investors) & self-referral
obesity crisis, threat of a diabetic generation vs. fast food culture and politics - the intersection of social and nutritional issues
the pending retirement of baby boomers and the pressures it will place on the health care system
management of chronic conditions (sig. problem for medicare now, will become bigger as baby boomers retire)
underutilization and availability of preventative care, general focus of medicine on reaction to acute injury rather than whole-health
private structures for health care - tax-free health savings accounts, encouragement of PPO's/HMO's (see medicare drug bill)
