Influenza vaccination of elderly individuals (65 years or older) has been recommended in the United States since 1961, and consistent surveillance of vaccine use has been conducted since 1989. We examined national trends in influenza vaccination coverage in the United States from 1989 to 2002 among noninstitutionalized elderly individuals and identified factors associated with receipt of influenza vaccine. ⋯ By 1997, influenza vaccination coverage exceeded the Healthy People 2000 objective of 60% for the elderly overall, but even by 2002, this objective was still not achieved in the elderly black and Hispanic populations. Vaccination coverage seems to be leveling off, and innovative initiatives are needed to reach the Healthy People 2010 target of 90%, especially among racial and ethnic minorities.

The prognostic role of echocardiographic right ventricular (RV) dysfunction for predicting mortality in patients with acute pulmonary embolism and a preserved systemic arterial pressure remains controversial. ⋯ Among patients with pulmonary embolism who present with a systolic arterial pressure greater than or equal to 90 mm Hg, echocardiographic RV hypokinesis is an independent predictor of early death.

Previous studies have investigated the impact of Staphylococcus aureus infections on individual hospitals, but to date, no study using nationally representative data has estimated this burden. ⋯ Staphylococcus aureus infections represent a considerable burden to US hospitals, particularly among high-risk patient populations. The potential benefits to hospitals in terms of reduced use of resources and costs as well as improved outcomes from preventing S aureus infections are significant.

It is unclear how frequently unprovoked venous thromboembolism (VTE) reflects the presence of an occult cancer. ⋯ In the year preceding the diagnosis of cancer, the number of cases with unprovoked VTE was modestly higher than expected, and almost all of the unexpected VTE cases were associated with a diagnosis of metastatic-stage cancer within 4 months. Given the timing and advanced stage of the unexpected cases, it is unlikely that earlier diagnosis of these cancers would have significantly improved long-term survival.

The role of patient-physician trust in moderating medication nonadherence due to cost pressures.
Prescription drug costs constitute a burden for many chronically ill adults and are strongly related to patients' likelihood of using less medication than prescribed. We examined the extent to which patients' trust in their physicians may moderate the impact of economic constraints and other risk factors for cost-related adherence problems. ⋯ These findings suggest that a trusting physician relationship may moderate the impact of cost pressures on patients' medication adherence. More generally, addressing noncost barriers to adherence may reduce rates of cost-related medication underuse.
