About Ann

Ann S. O’Malley is an expert in primary care health services research. She conducts both qualitative and quantitative research with a focus on improving support for primary care practices to provide more coordinated and comprehensive care, particularly for patients with multiple chronic conditions. She is the deputy director of the Center on Health Care Effectiveness.

O’Malley is a co-principal investigator and active member of the Mathematica team evaluating the Comprehensive Primary Care Plus (CPC+) model and also had a leadership role in evaluating the CPC Classic implementation. Her work for CPC+ includes leading the practice team that conducts qualitative research based on site visits to 100 primary care practices across 18 regions. She also contributes to quantitative data collection and analysis for CPC+ (and previously CPC Classic), including developing and revising surveys of primary care practices, clinicians, staff, and patients. In addition, O’Malley leads a team that developed two new Medicare claims-based measures on comprehensiveness of primary care. 

She also led several research projects on how electronic health records and other health IT tools support or hinder coordination of care and primary care teamwork. She recently completed a project on how accountable care organizations risk-stratify and segment their heterogeneous population of high-risk patients into smaller more actionable subgroups of patients with similar needs. O’Malley was also a task lead on the evaluation of the Impact and Diffusion of the Chronic Care Management fee.

O’Malley is board certified in preventive medicine and public health, has clinical training in pediatrics and preventive medicine, and completed a National Research Service Award fellowship in primary care research. She holds an M.D. from the University of Rochester School of Medicine and an M.P.H. in health policy and management from the School of Hygiene and Public Health, the Johns Hopkins University.

Key Projects
  • Evaluation of the Comprehensive Primary Care Initiative

    Mathematica and its partner, Group Health Cooperative, evaluated the effects of CPC on cost, quality, utilization, and patient and provider experience. We also provided rapid cycle (quarterly) feedback to participating practices, CMS, and CMS’s regional partners.
