MAPCP PCMH-CAHPS Surveys September 10, 2014 Presented by Kevin Smith
Objective • To determine how experiences reported by beneficiaries in MAPCP demonstration practices compare to national averages in 6 key domains
CAHPS Survey Design • Sample frame: Random sample of beneficiaries assigned to MAPCP demonstration practices who had had made at least one visit in previous quarter • Practice name inserted in first survey question • Medicare beneficiaries only • Mail surveys: initial and follow-up 3 weeks later • Initial mailing = 1,463 beneficiaries per state • Target = 512 completed surveys per MAPCP state • Surveys conducted in April and May 2014
CAHPS Survey Design • Rhode Island exception: * Administered PCMH-CAHPS to all practices in March * Obtained completed surveys for all 65+ beneficiaries
PCMH-CAHPS – 12-month version 6 Multi-item Composites: • Access to care (5 items) • Communication with Providers (6 items) • Office Staff Interactions (2 items) • Comprehensive Orientation (3 yes/no items) • Self-management Support (2 yes/no items) • Shared decision-making (3 items)
Composite Score Analysis • All composites converted to 0-100 scores (higher scores more favorable) • Two weighting adjustments: • Response propensity • Case-mix (age, education, health status) • Computed mean score and SE for each composite • Compared MAPCP means to two PCMH-CAHPS standards: • 1. CAHPS Database (320 practices reported to Westat) • 2. MA Health Quality Partners Study (MHQP; 1,790 patients)
Response Rates • Response rates were very similar across states • Beneficiaries least likely to complete surveys: age < 65 years and Medicaid eligibles
Summary • Response rates higher than projected • Many MAPCP composite scores fell between MHQP and CAHPS Database standards • MAPCP state scores were generally comparable to the composites from the CAHPS Database: • 17 scores significantly lower • 18 scores no significant difference • 13 scores significantly higher • Best comparative performance for: Self-Management Support and Comprehensive Orientation • Worst comparative performance for: Access to Care and Shared Decision-Making
