Introduction: Unmet social and economic needs are associated with poor health outcomes, but little is known about how these needs are predictive of future healthcare utilization. This study examined the association of social and economic needs identified during medical visits with future hospitalizations and emergency department visits.
Methods: Individuals with electronic health record-coded social and economic needs during a primary care, emergency department, or urgent care visit at Kaiser Permanente Northwest from October 1, 2016 to November 31, 2017 (case patients) were identified, as well as individuals who had visits during that time period but had no electronic health record-coded needs (control patients).
Background: The Prevention Index is a methodology for using electronic medical records to identify and evaluate practice variations in the delivery of preventive care.
Methods: The Prevention Index was used to evaluate the provision of 10 recommended adult preventive services using electronic medical record data for the years 1999 through 2002 among the 450,000 members of a large Northwest integrated care system. The analyses were conducted in 2005.
Objectives: Early detection through mammography can reduce breast cancer mortality. This cohort study evaluated trends in mammography screening, demonstrating a person-time approach.
