As a part of the regression modeling, we conducted both “unadjusted” and “adjusted” regression analyses.

The “unadjusted” models only contain indicators for health insurance type. The “adjusted” models contain these insurance indicators plus the individual characteristics kinase inhibitor listed in Exhibit 1. Exhibit 1. Survey Respondent Characteristics (Weighted) Results Survey Respondents Among the 3,014 survey respondents, 52% had private health insurance; 21% had Medicare (5% of all subjects were dual eligible for Medicare and Medicaid); 9% had Medicaid; and 18% were uninsured (Exhibit 1). Subjects differed considerably by insurance type with respect to socio-demographic, economic, and clinical characteristics. The percentage of private insurance beneficiaries with college degrees (53.5%) was higher

than the college-educated on Medicaid (17.2%) or who were uninsured (18%). More than half of all survey respondents were self-reported Internet users: 93% of privately insured adults and 56% of Medicare beneficiaries reported Internet use. Communication with health care providers occurs primarily offline (WITHOUT the Internet) Professional Advice (ALL RESPONDENTS):Thinking about the LAST time you had a serious health issue or experienced any significant change in your physical health… Did you get information, care or support from a doctor or other health care professional? All respondents were asked to indicate whether they sought professional advice (i.e., yes or no) and through what medium advice was sought (i.e., online, offline, or both online and offline). “Don’t know” and “Refused” options were available. Any respondents who were non-Internet users responding yes to this question were coded as yes,

offline responses. Substantially, more respondents reported seeking care through in-person visits or telephone calls than through online communication like email or Web messaging (Exhibit 2). Use of online consultations with a doctor varied across the insurance groups in unadjusted analysis (Exhibit 2), ranging from 12% of the AV-951 privately insured to 4% of uninsured adults. Exhibit 2. Percent Seeking Health Information from a Doctor, Any Online Efforts vs. Offline Only, by Insurance Type (unadjusted percent) After adjustment (Exhibit 3), Medicare beneficiaries had similar odds of seeking online consultations with doctors as privately insured adults (unadjusted OR=0.43, 95% CI: 0.37–0.50; adjusted OR=0.97, 95% CI: 0.80–1.17). After adjustment, Medicaid beneficiaries had greater odds (adjusted OR=1.45, 95% CI: 1.17–1.81) of seeking online physician consultations than privately insured adults (vs. having lower odds before adjustment, unadjusted OR=0.71, 95% CI: 0.59–0.85).
