Randomized Controlled Trial Multicenter Study Clinical Trial
Fecal hemoglobin excretion in elderly patients with atrial fibrillation: combined aspirin and low-dose warfarin vs conventional warfarin therapy.
Antithrombotic prophylaxis using combined aspirin and low-dose warfarin is under evaluation in several clinical trials. However, therapy may result in increased gastrointestinal blood loss and clinical bleeding vs conventional single-agent antithrombotic therapy. ⋯ Abnormal levels of fecal hemoglobin excretion were common in elderly patients with high risk of atrial fibrillation 1 month after randomization to prophylactic antithrombotic therapy. Combined warfarin and aspirin therapy was associated with greater fecal hemoglobin excretion than standard warfarin therapy, suggesting the potential for increased gastrointestinal hemorrhage.

Multicenter Study
Functional outcomes of acute medical illness and hospitalization in older persons.
Short-stay hospitalization in older patients is frequently associated with a loss of function, which can lead to a need for postdischarge assistance and longer-term institutionalization. Because little is known about this adverse outcome of hospitalization, this study was conducted to (1) determine the discharge and 3-month postdischarge functional outcomes for a large cohort of older persons hospitalized for medical illness, (2) determine the extent to which patients were able to recover to preadmission levels of functioning after hospital discharge, and (3) identify the patient factors associated with an increased risk of developing disability associated with acute illness and hospitalization. ⋯ This study documents a high incidence of functional decline after hospitalization for acute medial illness. Although there are several potential explanations for these findings, this study suggests a need to reexamine current inpatient and postdischarge practices that might influence the functioning of older patients.
