Research Abstract

My research topics in health care policy center on measurement of the
quality of care provided by health plans through consumer assessments and
clinical and administrative data. I am also interested in racial/ethnic
and socioeconomic disparities in quality of care. I am an investigator
on a project in collaboration with the California Cancer Registry and
regional registries that examines quality of care for colorectal cancer
using registry data, patient surveys, and a physician follow-back survey.
In this project we have developed new statistical methodology for correcting
treatment data in Registry records for underreporting. I am currently an
investigator in the NCI-funded CanCORS (Cancer Consortium for Outcomes
Research and Surveillance) study, both as part of the Statistical
Coordinating Center (based at DFCI) and through a research site that is a
collaboration of Harvard Medical School and the Northern California cancer
registries.

To these projects I bring my experience as a lead statistical investigator
in the core development project of the Consumer Assessments of Health
Plans Study (CAHPS), the CAHPS implementation for Medicare managed care,
and an AHRQ-funded project on expansion of the HEDIS clinical quality
measures. My statistical research interests include surveys, census
methodology, small area estimation, official statistics, missing data,
hierarchical modeling, and Bayesian methodology.
