Measure Methodology Change: From 2000-2007, the numerator is those who reported a big problem or a small problem to see a specialist. In 2008 and onward, the numerator of the measure is the number of people who reported it was never or only sometimes easy to see a specialist (2008-).
Inclusion Criteria: This measure includes people in the civilian non-institutionalized population who thought they needed to see, or whose doctor thought they needed to see a specialist. The Self Administered Questionnaire was administered to those 18 years and older.
Exclusion Criteria: Excluded from this measure are people in the military and the institutionalized population. Also excluded are people who did not think they needed to see a specialist, and whose doctor did not think they needed to see a specialist in the past 12 months. Those aged 0-17 are excluded.
