title: [Iatrogenic disease and self-injury: significant factors in hospital admission?].
abstract: The frequency of adverse effects caused by doctors may serve as a quality control. We therefore assessed the number of adverse effects leading to a hospital admission and occurring during a six-month period in the medical department of a district hospital. We compared these figures with the number of admissions caused by substance-abuse by the patient himself.
  
  
  RESULTS
  At admission to hospital 35 patients (6.4%) suffered from adverse effects. In 89% of these, the adverse effect was the leading factor to admit the patient; in the remaining 4 patients (11%) the adverse effect was detected by routine-screening upon admission. Further 8.6% developed adverse effects in the hospital which in 12.5% had consequences upon course and duration of the hospitalization. Self-afflicted hospital-admissions (substance-abuse, suicide-attempts) were found in 13%. Iatrogenic adverse effects brought 3.5% of the patients to the hospital.
  
  
  CONCLUSIONS
  Adverse effects caused by diagnostic and therapeutic activities of doctors considerably contribute to hospital-admissions and course of hospital-stay, but even more often the patient himself is responsible by his self-damaging behavior.
