Health Economics

  • (written as Iatrogenesis)
    An adverse condition induced in a patient through the effects of treatment by a health professional. It can arise in many ways: through clinical errors of diagnosis or treatment, through medical negligence, through environmental effects as in nosocomial infection, through the careless or deliberate flouting of best practice guidelines (as in the case of extensive prescribing of antibiotics for viral disease leading to antibiotic resistance), poor prevention practice and incompetent follow-up. As many (hospitalized) patients as an estimated 98 000 people die from iatrogenesis in the US each year (Kohn et al 1999).
