What are the desired outcomes of medical workforce policy?

• Access to care when it is wanted and needed.

• Care that is technically excellent and personally compassionate.

• Care that improves the health and well being of patients and populations.

• Care that is affordable to the patient and to society.

There is virtually no relationship

between regional physician supply and health needs.

Example 2: Are Cardiologists located where cardiac needs are greater?

Regional variation in physician supply is not explained by:

• Patient health status or health risk• Patients preference for care

Fisher E, et al. Ann Int Med 2003.NIA-CMS beneficiary survey, forthcoming.

No difference in preferences for aggressive care (dying in hospital, mechanical ventilation, or drugs that would lengthen their life, but make them feel worse)

No differences in concerns about getting too little (or too much) treatment

Somewhat lower preference for palliative care that would shorten life (80% want it in low spending regions, 75% in high spending).

So what?

Maybe more physicians leads to better health outcome.

Example 3: Do areas with higher physician supply have better health outcomes?

Example 4: Are health outcomes related to physician labor inputs?

So what?

Would a physician surge cause any harm?

Where do more physicians go?

1979

1999

Source: Goodman. Health Affairs, 2004.

For every physician that settled in a low supply

region, 4 physicians settled in a high supply region.

High Physician Supply Regions:

• High bed capacity, medical admission rates.

• High physician visit rates.

• High intensity care at the end of life.

• High costs.

• Lower perceived access.

• No better patient satisfaction.

• Worse technical quality.

• Greater tendency for physicians to use aggressive instead of conservative treatment.

• Physicians perceive care to be less available, less able to provide quality care.

• No better and perhaps worse patient outcomes.Sirovich B, et al. Ann Int Med 2006.

Where would you invest $5 billion per annum of public money in the

health care system?

• Improvements in care systems in an effort to improve quality.• Rewarding health care systems for improved outcomes.• Implementation of the U.S. Preventive Services Task Force

recommendations.• Expanding insurance coverage to children (S-CHIP).• Health insurance for returning Iraq war vets who aren't covered at

their jobs.• Establishment of effective post-marketing surveillance system for

drugs / devices.• Increasing physician training rates?
