Research interests are improving medical effectiveness and patient outcomes, use of management information systems to monitor quality of care, examining the impact of financing alternatives on cost and quality, and health system performance. Current research seeks to understand effective methods for increasing adherence to evidence-based practice and the impact of payment incentives on patterns of care and outcomes for chronic diseases. Has contributed to the literature on the impact of managed care and payments systems on access to care, quality, utilization, and cost. Was a co-developer of the widely used ACG (Adjusted Clinical Groups) case mix adjustment and co-developer of the Johns Hopkins HaH (Hospital at Home). Has developed methods for measuring provider continuity, needs and unmet needs for care, and measures of the timeliness of care. Has a particular interest in the role of routine management information systems (MIS) as source of data for evaluating the effectiveness and cost of health care. This includes work on the integration of outcomes management systems with existing MIS in managed care settings.
