Incidence of pulmonary embolism in elderly patients newly admitted to an acute geriatric unit: a prospective study.
To study the incidence of pulmonary embolism (PE) in elderly patients newly admitted to an acute geriatric unit, the authors carried out ventilation perfusion scans on 33 patients, 25 women and 8 men, mean age 79 years, consecutively admitted to the geriatric wards. The first scan was done within 5 days of admission and repeated between days 10 and 20. Where possible, patients with a positive second scan had a repeat scan at 2-3 months. Six (18%) patients were found to have a high probability of PE, 4 (12%) at the time of admission and two (6%) after admission. Three patients (9%) were considered to suffer from chronic pulmonary artery disease. Mortality was 5 for the whole group (15%) and 1 of 6 (17%) with a high probability of PE; this patient was suffering from carcinomatosis. The only patient who was anticoagulated suffered serious side effects. In no patient was PE clinically suspected. The authors conclude that PE is common in sick elderly patients newly admitted to acute geriatric wards, that rehabilitation with mobilization may precipitate new PE, and that nonanticoagulated PE does not seem to appreciably shorten the prognosis for life. Treatment with anticoagulants may be more dangerous than not treating PE in this older age group.
