A PILOT-STUDY TO ESTIMATE THE COST OF A TELEPHONE SURVEY OF RARE POPULATIONS - AFRICAN-AMERICANS AND PERSONS WITH ANGINA

Existing studies do not explain important differences in the utilizati on of health care services between African Americans and Whites with c oronary heart disease. Further advancement in understanding access to care differences may be obtained from a community survey. Such a surve y can be expensive because of the relative rarity of the populations o f interest. This pilot study provided estimates useful for calculating the level of effort required to conduct a telephone survey on access to care for persons with angina, an important presenting symptom for c oronary heart disease.
