OBJECTIVE: To assess the impact of a monetary incentive in a survey mailed to medical directors of large medical groups and independent practice associations (IPAs). STUDY DESIGN: Mailed survey. METHODS: We mailed a survey to the medical directors of all medical groups and IPAs contracted with Blue Cross California Care, a large California managed care health plan (n = 174). After 2 mailings without any monetary incentive, we included a $50 bill in the third mailing to increase the response rate. RESULTS: Only 46 medical directors responded to the first and second mailings (response rates of 17% and 13%, respectively). The third mailing, which included a $50 bill attached to the front of the survey, yielded 78 responses (66%), for an overall total of 124 (76%). We found no significant differences in the physician organizations of medical directors who responded to the mailing with the $50 incentive compared with the physician organizations of those who responded to 1 of the first 2 mailings, although medical directors who responded without the financial incentive were more likely to report that their organization had staff for quality assurance (96% vs 82%; P < or = .03). CONCLUSION: Including a $50 bill improved the rate of response to a survey mailed to medical directors from 13%-17% to 66%.
