Why? Aging? Obesity and Sickness? Waste and Inefficiency? Medical Malpractice? Technology

Technology in Healthcare Challenge: – High fixed-cost, low marginal cost – Heterogenous benefits (large value for some patients!) – Trials are often done in most appropriate patients – Financial incentives push for overuse in others

The Dark Side Can technology cause distractions? Theory of Technology Spillovers

What do Boards do on quality? Surveyed Board chairpersons from 1000 hospitals Received 78% response Oversampled “best” and “worst” hospitals on HQA processes Asked about priorities, perceptions, and activities around quality Jha and Epstein, Health Affairs, 2010

Perception of Quality Performance Note: Perception of their hospital’s performance on the TJC/HQA measures compared to typical U.S. hospital

Board’s Attention to Quality

So what’s the bottom line? Technology growth drives healthcare spending New Technologies have ‘high-fixed-cost, low marginal cost’ profile New technologies have heterogeneous benefits– cost effectiveness very hard to do! Spending is weakly correlated with outcomes Outcomes are affected by professionalism, diligence, and safety culture Real cost of technology is that it distracts from safety Hard choices ahead– don’t be fooled by prevention as a solution for technology growth
