Iatrogenesis (from the Greek for "brought forth by the healer") refers to any effect on a person, resulting from any activity of one or more persons acting as healthcare professionals or promoting products or services as beneficial to health, that does not support a goal of the person affected. 〔http://medical-dictionary.thefreedictionary.com/Iatrogenesis〕 〔http://www.merriam-webster.com/medical/iatrogenesis〕 〔https://books.google.com/books?id=kUkjRSyWNmYC&lpg=PA1967&ots=CgSaTqCIqN&dq=Dorland%20Medical%20dictionary%20iatrogen&pg=PA1967#v=onepage&q=Dorland%20Medical%20dictionary%20iatrogen&f=false〕 〔https://books.google.com/books?id=QfiLuC7a47sC&lpg=PA55&ots=mVTRpfWLit&dq=Dorland%20Medical%20dictionary%20iatrogen&pg=PA55#v=onepage&q=Dorland%20Medical%20dictionary%20iatrogen&f=false〕 〔https://books.google.com/books?id=ByFhcDveoK0C&lpg=PA336&ots=QffM5d1dxp&dq=Dorland%20Medical%20dictionary%20iatrogen&pg=PA336#v=onepage&q=Dorland%20Medical%20dictionary%20iatrogen&f=false〕 〔http://www.encyclopedia.com/doc/1O88-iatrogenesis.html〕 Some iatrogenic effects are clearly defined and easily recognized, such as a complication following a surgical procedure (''e.g.'', lymphedema as a result of breast cancer surgery). Less obvious ones, such as complex drug interactions, may require significant investigation to identify. While some have advocated using 'iatrogenesis' to refer to all 'events caused by the health care delivery team', whether 'positive or negative', consensus limits use of 'iatrogenesis' to adverse, or, most broadly, to unintended outcomes. Causes of iatrogenesis include: * side effects of possible drug interactions * chance * medical error * negligence * unexamined instrument design * anxiety or annoyance in the physician or treatment provider in relation to medical procedures or treatments * unnecessary treatment for profit Unlike an adverse event, an iatrogenic effect is not always harmful.〔 For example, a scar created by surgery is said to be iatrogenic even though it does not represent improper care and may not be troublesome. Professionals who may cause harm to patients include physicians, pharmacists, nurses, dentists, psychologists, and therapists. Iatrogenesis can also result from complementary and alternative medicine treatments. Globally it is estimated that 142,000 people died in 2013 from adverse effects of medical treatment up from 94,000 in 1990. ==Sources== Examples of iatrogenesis: * Risk associated with medical interventions * * Adverse effects of prescription drugs * * Over-use of drugs, (causing - for example - antibiotic resistance in bacteria) * * Prescription drug interaction * Medical error * Wrong prescription, perhaps due to illegible handwriting, typos on computer. * Negligence * Nosocomial infections * Faulty procedures, techniques, information, methods, or equipment. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Iatrogenesis」の詳細全文を読む スポンサード リンク
