Trajectory Model Juliet Corbin and Anselm Strauss Date of last revision September 24, 2011 Introduction Trajectory Modelis a nursing model particularly applicable in situations of people with chronical diseases developed by Anselm L. Straus, medical sociologist and Juliet Corbin, a nurse theorist. This model is also called “Corbin-Strauss-Model” and is recognised as a middlerange explanatory nursing theory (Corbin & Straus, 1991) This model was developed following over 30 years of interdisciplinary research on a variety of chronic illnesses. Definitions Trajectory -“a course of illness over time plus the actions taken by patients, families and health professionals to manage or shape the course”The term “trajectory” refers to the course of a chronical disease in its different stages and phases. Chronic Illness Chronical illnesses are serious diseases which could last the whole life of the concerned person affecting the person’s mental, emotional and social well-being. Eight stages of the course of disease McCorkle & Pasacreta, 2001- explains eight phases of chronic illness trajectory Initial or pretrajectory phase - occurs before any signs and symptoms are present. Trajectory onset phase- occurs with the first onset of signs and symptoms and includes the diagnostic period. The crisis phase -is when a potentially life-threatening situation arises The acute phase- follows the crisis phase and refers to the period when the patient's symptoms can be controlled by a prescribed regimen. Stable phase - this phase starts once symptoms are controlled. Unstable phase - when the patient's symptoms are uncontrolled by the previously adopted regimen Downward phase - characterized by progressive deterioration in mental and physical status Dying phase - refers to a period of weeks, days, or hours preceding death .
