Chronic Critical Illness[edit]

Chronic critical illness (CCI) is a condition characterized by prolonged dependence on intensive medical care, often following an acute critical illness. Patients with CCI typically require extended stays in intensive care units (ICUs) and may experience a range of complex medical issues, including respiratory failure, sepsis, and multiorgan dysfunction syndrome.

Definition and Characteristics[edit]

Chronic critical illness is defined by the need for prolonged mechanical ventilation and intensive medical support. Patients often have a tracheostomy and require ongoing respiratory therapy. The condition is associated with high morbidity and mortality rates, and patients frequently experience significant physical and cognitive impairments.

Causes[edit]

The development of CCI can result from various acute critical illnesses, such as severe pneumonia, acute respiratory distress syndrome (ARDS), or major trauma. These conditions can lead to prolonged ICU stays and the need for extended medical interventions.

Management[edit]

Management of CCI involves a multidisciplinary approach, including the expertise of respiratory therapists, intensivists, nurses, and physical therapists. Key aspects of care include:

Respiratory Support: Prolonged mechanical ventilation and weaning strategies.
Nutritional Support: Enteral or parenteral nutrition to meet metabolic demands.
Infection Control: Prevention and treatment of infections, particularly ventilator-associated pneumonia.
Rehabilitation: Physical and occupational therapy to improve functional outcomes.

Prognosis[edit]

The prognosis for patients with CCI is generally poor, with high rates of mortality and long-term disability. Survivors often face significant challenges, including muscle weakness, cognitive impairment, and reduced quality of life.

-'''Chronic Critical Illness''' ('''CCI''') is a medical condition characterized by the persistence of severe acute illness, requiring prolonged intensive care unit (ICU) support, including mechanical ventilation and other life-sustaining interventions. Patients with CCI often experience a complex interplay of medical, psychological, and functional challenges that extend beyond their hospital stay, impacting their quality of life, and placing a significant burden on healthcare systems and caregivers.

-Chronic critical illness is not defined by a single criterion but rather by a constellation of clinical features. These typically include prolonged mechanical ventilation (beyond 14 days), tracheostomy, repeated or persistent organ failures, and a high degree of dependency on medical care. The prevalence of CCI has been increasing, attributed to advancements in critical care medicine that have improved survival from acute critical illnesses, leading to a growing population of patients who survive but do not fully recover.
-==Pathophysiology==
+[[File:Respiratory_therapist.jpg|thumb|right|A respiratory therapist providing care to a patient.]]
-The pathophysiology of CCI is complex and multifactorial, involving persistent inflammation, immunosuppression, and catabolism syndrome (PICS). This syndrome is characterized by ongoing inflammatory response, weakened immune defenses, and severe muscle wasting, contributing to the prolonged recovery and high morbidity associated with CCI.

-* Persistent need for mechanical ventilation
-* Tracheostomy
-* Recurrent or persistent infections
-* Poor wound healing
-* Nutritional deficiencies
-* Muscle wasting and weakness
-* Cognitive impairments
-==Management==
+=== Causes ===
-The management of CCI is multidisciplinary, focusing on optimizing organ function, preventing complications, and enhancing quality of life. Key components include:

-* Tailored nutritional support
-* Physiotherapy and rehabilitation
-* Psychological support and cognitive rehabilitation
-* Palliative care, when appropriate
-==Outcomes==
+=== Management ===
-The outcomes for patients with CCI are variable, with many experiencing prolonged hospitalizations, frequent readmissions, and significant functional impairments. Mortality rates are high, and survivors often face a diminished quality of life.

-CCI raises important ethical considerations, including decisions about the initiation and withdrawal of life-sustaining treatments. The economic impact is also significant, with CCI patients accounting for a disproportionate share of healthcare resources.
+* '''Nutritional Support''': Enteral or parenteral nutrition to meet metabolic demands.
+* '''Infection Control''': Prevention and treatment of infections, particularly [[ventilator-associated pneumonia]].
