Frail and disabled older adults are at risk for hospitalization and premature institutionalization, due to the complex interplay among age-related deficits, manifestations and treatment of disease, and behavioral, social and economic factors (Maas et al. 2001). For example, cognitive
impairment, including memory lapses and loss of executive
function, may conspire with visual impairment and poverty
to interfere with taking medication as prescribed.
