What Was Measured?

The number of male and female commercial HMO and point of service (POS) enrollees in California’s largest health plans. 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 2010 Quality Compass®, and is part of the same HMO data set used to generate the HEDIS and CAHPS quality information found in the health plan section of the 2011 OPA Report Card.
