Abstract:
|
Surveying the Medicaid population by telephone usually requires access to the Medicaid program administrative data to obtain contact information. What if the administrative data contain no telephone numbers? This is the case in a study of the Medicaid recipients in California. The state administrative database contains addresses of the Medicaid recipients, but no telephone numbers. The study protocol requires that the survey be conducted by telephone. An alternative solution is adopted in which the addresses of the Medicaid recipients are used to look up phone numbers from published and unpublished telephone directories. This paper discusses the process of the look-up, the verification of the phone numbers obtained through the look-up, the effectiveness of this approach for reaching the Medicaid population, and implications for other special populations with similar contact data limitations.
