Session Description/Moderator Details.– Evidence-based medicine in geriatrics Geriatric patients often have multiple chronic conditions, use many medications and may suffer from cognitive and functional impairments. A study about prevalence of morbidities in the elderly showed, that 82% of patients aged 65 and over had at least one chronic condition; 24% had even four or more conditions [1]. Due to deteriorating organ functions they are prone to medication-related side effects [2]. Considering these complex problems, arriving at the best treatment for individual older people is complicated.
