Selected Research

Costs Associated with Ambulatory Care Sensitive Conditions Across Hospital-based Settings

In this work, published in Academic Emergency Medicine (2015;22:172-81. doi: 10.1111/acem.12579), Dr. Galarraga and colleagues investigated conditions that could be prevented through improved access and quality of primary care and compared cost expenditures for outpatient, emergency department, and inpatient visits for these conditions. Expanded access to outpatient resources and improved health management for these conditions can avoid more expensive hospital-based encounters.
