Complication (medicine)

Complication, in medicine, is an unfavorable evolution or consequence of a disease, a health condition or a therapy. The disease can become worse in its severity or show a higher number of signs, symptoms or new pathological changes, become widespread throughout the body or affect other organ systems. A new disease may also appear as a complication to a previous existing disease. A medical treatment, such as drugs or surgery may produce adverse effects or produce new health problem(s) by itself. Therefore, a complication may be iatrogenic (i.e. literally brought forth by the physician).[1]

Medical knowledge about a disease, procedure or treatment usually entails a list of the most common complications, so that they can be foreseen, prevented or recognized more easily and speedily.

Depending on the degree of vulnerability, susceptibility, age, health status, immune system condition, etc. complications may arise more easily. Complications affect adversely the prognosis of a disease. Non-invasive and minimally invasive medical procedures usually favor fewer complications in comparison to invasive ones.

Disorders that are concomitant but are not caused by the other disorder are comorbidities. This conceptual dividing line is sometimes blurred by the complexity of the causation or the lack of definite information about it. The terms sequela and complication are often synonymous, although complication connotes that the resultant condition complicates the management of the causative condition (makes it more complex and challenging).[2]

Complications are not to be confused with sequelae, which is a residual effect after the acute phase of an illness of injury. Sequelae can appear early or weeks to months later and due to the previous injury or illness. For example, a scar after a burn or dysphagia left after a stroke would be considered sequelae.[3]

A complication is an adverse event that occurs due to a medical treatment or surgical procedure. Examples of complications would be bleeding after surgery, headache after a spinal tap, or an adverse drug reaction.

CausesEdit

There may be financial pressures which act in opposition to preventing complications. A United States study found that hospitals make more money per patient when patients have complications.[10]
