[On informed patient consent]

One third of all lawsuits against doctors include statements of insufficient or lacking informed consent. The objectives of this prospective study in 104 patients were to elucidate the actual clinical routine of obtaining informed consent (process quality), collect information on active and passive recall 3 to 7 days p.op., and to investigate whether patient age, sex, education, profession, and cognitive function using the Mini Mental State Test, the time from obtaining consent to interview, acuity (emergency vs elective cases), and quantity of patient/doctor interaction would influence the patient's recall capabilities. In clinical routine, obtaining informed consent is a very variable procedure, and between two and 18 items were documented by the physician. Of the patients, 12.6% recalled actively and 43.5% passively. They named between 1.1 and 3.7 items on average, with "infection" as the leading complication, followed by "pain" and "lesion of nerves". Of all parameters investigated, only the number of initially documented items exhibit a significant effect on the patients' recall. The quantity of patient/physician interaction not only guarantees an increased effect on recall but also means improves patient interaction, thereby reducing the probability of imminent accusations.
