Iatrogenesis

*Iatrogenia*

Iatrogenesis refers to the development of diseases or pathological complications directly related to the actions of medical personnel during therapeutic, diagnostic, or preventive measures.

Definition and origin of the term

The word iatrogenia is formed by combining the Greek roots iatros (physician) and genes (arising, caused by). In pathological anatomy, this term refers to any adverse consequences of medical procedures—whether diagnostic, therapeutic, or preventive. The primary outcome of such interventions is impaired bodily function, disability, or the death of the patient.

In the structure of a pathomorphological diagnosis, such conditions occupy a special place and are always entered directly under the "primary disease" category.

Classification of medical actions

The actions of medical personnel resulting in adverse outcomes are divided into two main categories:

  1. Medical error — a conscientious misjudgment by a healthcare professional in the performance of their professional duties. The main criterion is that the specific physician could not foresee and prevent such an outcome. Such situations exclude negligence, ignorance, or malicious intent.
  2. Medical misconduct (crime) — a situation where the specialist had a realistic opportunity to foresee and prevent negative consequences, but failed to do so.

Causes and legal status of medical errors

The occurrence of medical errors is driven by objective factors:

  • lack of professional experience in the specialist;
  • absence of currently required laboratory or instrumental capabilities for accurate diagnosis.

As for medical misconduct, its cause is most often negligence (failure to fulfill direct duties) or mercenary motives. Such an incident leads to severe or fatal outcomes, but the legal status and the commission of a crime can be established exclusively by a court.

Briefly: answers to topical questions

How to properly structure a complete pathomorphological diagnosis in cases of iatrogenesis?

The provided materials do not describe the complete structure of a pathomorphological diagnosis for iatrogenic conditions. Only the main rule for their formatting is indicated: iatrogenic conditions are entered under the "primary disease" category.

Iatrogenesis itself is defined as any adverse consequences of preventive, diagnostic, or therapeutic interventions that have led to functional impairment, disability, or death of the patient. Within the framework of diagnostic theory, they are considered independent diseases or pathological processes caused by the actions of medical personnel.

What specific pathological processes and complications most frequently act as iatrogenic conditions?

The provided materials cite the following iatrogenic diseases, pathological processes, and complications:

  • Hemorrhagic syndromes — arising due to the use of direct and indirect anticoagulants, antiplatelet agents, and fibrinolytics.
  • Pulpitis — toxic, including iatrogenic, caused by medications and filling materials when treatment protocols are violated.
  • Cystitis — hemorrhagic cystitis during cytotoxic drug therapy and radiation cystitis following irradiation of the bladder area.
  • Pericarditis — secondary iatrogenic pericarditis, as well as pericarditis following cardiac surgery or radiation therapy.
  • Iatrogenic Cushing's syndrome — caused by medication intake.
  • Granulocytopenia — following radiation or cytostatic therapy, as well as treatment with toxic drugs.
  • Chylothorax and injuries of the thoracic lymphatic duct — including postoperative iatrogenic injuries and those associated with central venous catheterization.
  • Secondary gout — during cytostatic therapy and prolonged diuretic treatment.
  • Bradyarrhythmias — may have a drug-induced iatrogenic nature.
  • Acquired prion diseases — an iatrogenic transmission route of the infectious agent is possible.
  • Acute infective endocarditis — iatrogenic causes are possible, including heart surgery and chamber probing.
  • Cardiogenic shock — among other causes, iatrogenic catheterization complications, overdose, or unjustified prescription of β-blockers or calcium channel blockers are indicated.
  • Hemoptysis and hemorrhages — possible during anticoagulant therapy.

Class and exam questions

What falls under iatrogenic conditions in pathological anatomy?

These are any adverse consequences of diagnostic, preventive, or therapeutic interventions by medical personnel that have led to functional impairment, disability, or death of the patient.

Where is iatrogenesis entered when formulating a diagnosis?

According to the rules of pathological anatomy, iatrogenic conditions are entered directly under the "primary disease" category.

How does a medical error differ from misconduct?

An error is a conscientious misjudgment due to a lack of experience or capabilities that the physician could not prevent. Misconduct (crime) is committed due to negligence or self-interest, when the specialist had the opportunity to avoid the consequences but neglected their duties.

Who establishes the fact of a medical crime?

The fact of medical misconduct (crime) has a special legal status and is established exclusively by a court.
