Hospital transfer of patients with acute myocardial infarction: the effects of age, race, and insurance type.
Many factors precipitate the transfer of patients hospitalized for acute myocardial infarction, including clinical status and the need for diagnostic testing and therapeutic interventions not available at the admitting hospital. The objectives of this study were to assess the frequency of transfer to another hospital and to determine whether nonmedical factors, such as age, sex, race, and insurance status, are associated with transfer. ⋯ Our findings suggest that nonmedical factors, including age, race, and insurance type, affect decisions regarding the transfer of patients hospitalized with acute myocardial infarction. As only a minority of the nation's hospitals offers a full range of cardiovascular diagnostic and therapeutic procedures, these findings reinforce ongoing concerns about disparities in access to health care services for some patients.

Patients with chronic obstructive pulmonary disease (COPD) and elderly individuals are prone to the development of significant lower respiratory tract symptoms from colds caused by viral respiratory pathogens. Longitudinal surveillance studies conducted to assess the impact of viral respiratory tract pathogens on morbidity and mortality in each of these at-risk populations demonstrate that there is a substantial burden of disease from viral respiratory infection (VRI), including rhinovirus infections, with respect to utilization of health-care resources. Despite a similar rate of occurrence of VRI among subjects with COPD and the control group, a cohort with moderate to severe COPD had a 2-fold increase in medical resource utilization, including clinician visits, emergency center visits, and hospitalizations. In surveillance studies of respiratory viruses in the elderly, regular seasonal infections with rhinoviruses cause substantial morbidity, which has been largely underappreciated and underreported.

Acute respiratory tract infections are the most common illnesses in all individuals, regardless of age or gender. Epidemiologic surveys and community-based studies conducted since the beginning of the 20th century have determined the rates of illness and the pathogens involved in such infections. These studies have shown that rhinoviruses cause the great majority of these respiratory illnesses, and their findings have examined the means of transmission of respiratory illness. More recently, advances in diagnostic techniques have enabled more complete identification of the viruses involved in respiratory infections, which has aided in the ability to direct specific therapeutic agents at the causative pathogens.

Because of suggestions that hypertension may increase the long-term risk of cancer, we assessed the relation between hypertension and malignancy. ⋯ Hypertension was associated with an increased risk of mortality from cancer, particularly renal cell carcinoma.
