[On informing in-patients, and the problem of hospitalism (author's transl)]

Sixty-seven in-patients, admitted to neurological or surgical wards of an acute hospital, were repeatedly interviewed during an average stay of 15 days to test their need for information about their illness, their satisfaction with information received and their knowledge about their illness. Parallel to these interviews psychometric tests were performed on the second, seventh and penultimate day of the hospital stay, in the evening, to assess the extent of any disturbance in their subjective condition. Independent of the initial state, there were consistently less favourable results in those patient groups which (using several indicators) had a deficit in subjective information. These group-specific differences were in part statistically significant. An intervening influence of 12 personality dimensions was not definitely established. These findings support the hypothesis that deficient instruction and information of in-patients represents an important stress component which in the majority of these patients can give rise to an objectifiable psychosocial hospitalism.
