HMO/POS Membership by Gender

What Was Measured?

The number of male and female commercial HMO and point of service (POS) enrollees in California’s largest health plans in the 2005 calendar year. HMO/POS enrollment information is not ranked because it is not a quality measure.

Why Is It Important?

Enrollees may feel more comfortable in one HMO or POS plan than another depending on the range of covered services, the perceived stability of the HMO or POS plan, or the availability of different types of physicians who best meet their needs. The number of male and female enrollees in an HMO or POS plan is one indication of how Californians select their HMO or POS.

What Was the Source?

Data on HMO and POS enrollees voluntarily reported by California health plans to the National Committee for Quality Assurance (NCQA) and made available through NCQA’s Quality Compass®. HMO and POS data are reported together here because Quality Compass® does not separate HMO and POS membership in it’s report. The HMO/POS Membership by Gender data comes from NCQA’s 2005 Quality Compass®, and differs from the 2006 HEDIS and CAHPS quality information found in the 2006 OPA Report Card.
