This presentation will:

1. Provide a brief overview of the methodology of the 2005 KP-NCal Adult Member Health Survey

2. Show estimated IT access (personal computer, Internet, and email) by age and gender and level of education

3. Show estimated use of Kaiser and non-Kaiser websites during the 12 months prior to the survey to communicate with the health care system and seek health-related information, by age and gender and level of education.

4. Show estimated interest in using IT technologies to learn about health and how to take care of oneself, by age and gender and level of education.

MHS Study Design:• Separate samples pulled for 19 KP-NCal Medical Center

Service Populations (MCSP) based on outpatient use during 4th quarter 2004 or administrative assignment if no outpatient utilization.

• MCSP samples consist of 2,100+ men and women aged > 20, stratified by 5 age groups (20-44, 45-64, 65-74, 75-79, 80+); larger samples for 5 facilities with high estimated %s members of color (OAK, RCH, SFO, HAY, VAL)

• Eligibility criteria: Current member, not LEP (survey only available in English); LOE and utilization history not considered

• Survey mailed in April 2005, with up to 2 mailed follow-ups • Survey respondents assigned a post-stratification weighting

factor based on age-gender composition of MCSP and of final respondent sample → Weighted samples better reflect age-gender compositions of the MCSP (and Region)

In 2005, web-based survey option offered in addition to hardcopy survey:

• Designed to appeal to younger adults who have always been our worst responders; most adults > 65 not expected to choose electronic questionnaire option

• Survey packet (questionnaire, cover letter + FAQ, return envelope) sent out to entire sample. URL of web-based survey, logon ID and passcode included in the letter– Couldn’t send out an e-mail link because we do not have

members’ e-mail addresses, but KP-NCal IRB would likely not have approved contacting members by e-mail anyway.

• Only 2.4% (454 / 18,750) of survey respondents chose to complete the survey on our secure website: 6.4% (n=132) men 25-44, 3.5% women 25-44 (n=132), and 3.9% of men 45-64 (n=104); <1% of men and women aged ≥ 65 chose web option
