More on over-diagnosis. Quote:
….the drivers of this phenomenon are complex and multifaceted. These include professional and commercial self-interest; litigation fears; our cultural love affairs with early diagnosis and the wonders of technology; and the nature of the health system itself, where a fee-for-service system brings benefits for doing more tests, more treatments, more procedures. But research evidence is starting to suggest that, in many situations, less may be more.
There will be an international meeting on over-diagnosis at the Dartmouth Institute for Health Policy and Clinical Practise a year from now, which will likely result in some good analysis and suggested policies to reduce over-diagnosis.
