I talk with TROY BRENNAN, professor at the Harvard T. H. Chan School of Public Health and former Chief Medical Officer at CVS Health about his latest book, WONDERFUL AND BROKEN: The Complex Reality of Primary Care in the US. The US accounts for roughly half of total global health care spending, even though it’s only 4% of world population. The World Health Organization ranks US healthcare 37th overall compared to other Western countries. Primary care physicians play a pivotal role in both preventing disease and lowering healthcare costs but they are overworked, underpaid, and incentivized to move into higher-paying specialties while patients face provider shortages.
