Older adults with cardiovascular disease (CVD) or CVD risk factors report that gaps in communication among their providers are common and hazardous.

The successful collaboration between a primary care–based network of practices and academic researchers demonstrates feasibility and the need for more funding for primary care research.

The authors examined the association of diabetes with self-reported gaps in care coordination and self-reported preventable adverse events using data from a national sample of older adults.

Among older Black adults taking antihypertensive medication, fragmented ambulatory health care was associated with an increased likelihood of apparent treatment-resistant hypertension with uncontrolled blood pressure.

This article examines the association between a large-scale primary care redesign—the Comprehensive Primary Care Plus Initiative—and ambulatory care patterns of Medicare beneficiaries with highly fragmented care.

Having highly fragmented ambulatory care and a usual provider of care outside the Veterans Health Administration increased the odds of hospitalization among veterans with diabetes.

Transitioning from Medicaid fee-for-service to Medicaid managed care was associated with a significant decrease in ambulatory utilization, especially among beneficiaries with 5 or more chronic conditions.

Among Medicaid beneficiaries, having more fragmented ambulatory care was associated with a modest independent increase in the hazard of a subsequent emergency department visit.

Among Medicare beneficiaries, the relationship between fragmented ambulatory care and subsequent emergency department visits and hospital admissions varies with the number of chronic conditions.

Use of specialist visits decreased by patients whose primary care physicians transformed their practices into patient-centered medical homes, 1 year after medical home implementation.

Usage of a health information exchange system at the point of care reduced the occurrence of repeat imaging procedures in a multi-payer community sample.

Although health information technology interventions are associated with cost savings and revenue gains, there still are few articles on this topic.

In this study, the Patient-Centered Medical Home was associated with improvements in patients' experience with access to care but not other domains of care.

This framework suggests new meaningful use measures and guidance for prioritizing implementation of different health information technology functionalities, based on their expected financial effects.

Communities led by health information organizations were more likely than those led by healthcare organizations to receive ongoing funding for implementing health information technology.
