Does the form of medical practice affect health care utilization and costs?

The growth of larger multispecialty physician practices prompts questions about the effects of practice organization on health care delivery, outcomes, and costs. We use Medicare claims data from 2006-2020 to examine differences in spending, health care utilization, and quality for traditional Medicare patients who receive primary care from practices that only have primary care physicians (“PC-only practices) and those who receive primary care in typically larger multispecialty practices that integrate primary care and other specialist physicians. We focus on individuals who move from one HRR to another, and use changes in practice type associated with the move to identify effects of practice type, controlling for individual and geographic characteristics, and time trends. We find that receiving primary care in a PC-only practice is associated with an increase of $341 per year in total spending. This is primarily associated with higher rates of hospitalization and post-acute care use. PC-only practices are also associated with higher rates of AHRQ Prevention Quality Indicators, suggesting a possibility of lower quality care. Overall, these results suggest that larger, multispecialty practices may be able to improve the efficiency, and lower the overall cost, of care for Medicare recipients.
