Background: Few studies report on the effect of organizational factors facilitating transfer between primary and tertiary care hospitals either within an integrated health care system or outside it. In this paper, we report on the relationship between degree of clinical integration of cardiology services and transfer rates of acute coronary syndrome (ACS) patients from primary to tertiary hospitals within and outside the Veterans Health Administration (VHA) system. Methods: Prospective cohort study. Transfer rates were obtained for all patients with ACS diagnoses admitted to 12 primary VHA hospitals between 1998 and 1999. Binary variables measuring clinical integration were constructed for each primary VHA hospital reflecting: presence of on-site VHA cardiologist; referral coordinator at the associated tertiary VHA hospital; and/or referral coordinator at the primary VHA hospital. We assessed the association between the integration variables and overall transfer from primary to tertiary hospitals, using random effects logistic regression, controlling for clustering at two levels and adjusting for patient characteristics. Results: Three of twelve hospitals had a VHA cardiologist on site, six had a referral coordinator at the tertiary VHA hospital, and four had a referral coordinator at the primary hospital. Presence of a VHA staff cardiologist on site and a referral coordinator at the tertiary VHA hospital decreased the likelihood of any transfer (OR 0.45, 95% CI 0.27–0.77, and 0.46, p = 0.002, CI 0.27–0.78). Conversely, having a referral coordinator at the primary VHA hospital increased the likelihood of transfer (OR 6.28, CI 2.92–13.48). Conclusions: Elements of clinical integration are associated with transfer, an important process in the care of ACS patients. In promoting optimal patient care, clinical integration factors should be considered in addition to patient characteristics.

Ischemic heart disease (IHD) is the leading cause of death in the United States. Lowering serum cholesterol levels reduces coronary events and mortality; this effect is most evident in patients with preexisting IHD. The primary aim of this article is to describe a set of interventions that were piloted in a single, regional Veterans Integrated Service Network (VISN) to promote secondary prevention among patients with IHD and to explore the effect of those interventions on patient outcomes. An observational, before-and-after study of clinical interventions to improve lipid guideline compliance in VISN 20 (the Veterans Administration Northwest Network) was conducted. A total of 2,467 patients with established coronary artery disease from three medical facilities in VISN 20 were included. Each medical facility chose different interventions to lower low-density lipoprotein cholesterol (LDL-c) levels in their patients. One facility chose a paper point-of-care reminder, a second chose a lipid clinic, and a third chose audit/feedback to clinicians in addition to a patient-education component. Data came from a relational database that mirrors the clinical information system at each site. Outcomes included the proportion of patients who had their LDL-c measured, the proportion of patients who had lipid-lowering agents prescribed, and the proportion of patients at LDL-c goal of lower than 100 mg/dL measured before, during, and after the intervention period. Statistically significant improvements were observed within sites after the interventions were implemented. Interventions that focused on secondary prevention in this high-risk group were moderately successful in changing practice. Tailoring interventions to the needs of a specific site of care is feasible and may add to the likelihood of succeeding. Overall, the three facilities improved in lipid measurement and management for patients with coronary artery disease.
