Secondary prevention is of importance when the patient is already suff
ering from a serious disease, e. g., from arterial obstruction causing
a stroke or an amputation, from a hip fracture or other diseases that
might threaten his independence. Secondary prevention covers a wide f
ield of topics. First of all, the patient must recover from his acute
disease. It is important to avoid complications which are not specific
for the disease, but are typical for a bedridden old person (decubita
l ulcer, dehydration and others). Prevention also means to avoid recur
rence of the same disease as well as complications that frequently occ
ur during the clinical course and may influence the outcome (spasticit
y in stroke patients, muscular calcification following hip replacement
). Frequently, old persons do not completely recover following serious
disease, they are limited in their daily activities and their capabil
ity to leave home. Secondary prevention tries to fight isolation; the
patient should live a meaningful life.
