Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body. Sedentary work involves sitting most of the time, but may involve walking or standing for brief periods of time. Jobs are sedentary if walking and standing are required only occasionally and other sedentary criteria are met.

Light Work Exerting up to 20 pounds (9.1 kg) of force occasionally and/or up to 10 pounds (4.5 kg) of force frequently, and/or negligible amount of force constantly to move objects. Physical demand requirements are in excess of those for Sedentary Work. Light Work usually requires walking or standing to a significant degree. However, if the use of the arm and/or leg controls requires exertion of forces greater than that for Sedentary Work and the worker sits most the time, the job is rated Light Work.

Medium Work Exerting up to 50 (22.7 kg) pounds of force occasionally, and/or up to 25 pounds (11.3 kg) of force frequently, and/or up to 10 pounds (4.5 kg) of forces constantly to move objects.

Heavy Work Exerting up to 100 pounds (45.4 kg) of force occasionally, and/or up to 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Very Heavy Work Exerting in excess of 100 pounds (45.4 kg) of force occasionally, and/or in excess of 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Job Classification

In most duration tables, five job classifications are displayed. These job classifications are based on the amount of physical effort required to perform the work. The classifications correspond to the Strength Factor classifications described in the United States Department of Labor's Dictionary of Occupational Titles. The following definitions are quoted directly from that publication.

Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body. Sedentary work involves sitting most of the time, but may involve walking or standing for brief periods of time. Jobs are sedentary if walking and standing are required only occasionally and other sedentary criteria are met.

Light Work Exerting up to 20 pounds (9.1 kg) of force occasionally and/or up to 10 pounds (4.5 kg) of force frequently, and/or negligible amount of force constantly to move objects. Physical demand requirements are in excess of those for Sedentary Work. Light Work usually requires walking or standing to a significant degree. However, if the use of the arm and/or leg controls requires exertion of forces greater than that for Sedentary Work and the worker sits most the time, the job is rated Light Work.

  • Acute stress disorder
  • Alcohol/substance-related delirium
  • Anxiety disorders
  • Brief psychotic disorder
  • Delirium due to a general medical condition
  • Dementia
  • Mood disorders
  • Other psychotic disorders

Comorbid Conditions

Factors Influencing Duration

The nature and responsiveness to treatment of the underlying disorder greatly influence duration of disability. Individuals with terminal medical conditions, such as end-stage renal or liver disease, end-stage AIDS, or terminal cancer, show long-lasting symptoms of delirium. Individuals with higher premorbid performance in cognitive and physical areas generally have better recoveries.

Medical Codes

ICD-9-CM:
290.11 - Presenile Dementia with Delirium; Presenile Dementia with Acute Confusional State
290.3 - Senile Dementia with Delirium; Senile Dementia with Acute Confusional State
290.41 - Vascular Dementia with Delirium; Arteriosclerotic Dementia with Acute Confusional State
291.0 - Alcohol Withdrawal Delirium; Alcoholic Delirium; Delirium Tremens
292.81 - Drug-induced Delirium
293.0 - Delirium Due to Conditions Classified Elsewhere; Acute Confusional State, Infective Psychosis; Organic Reaction, Posttraumatic Organic Psychosis, Psycho-organic Syndrome; Acute Psychosis Associated with Endocrine, Metabolic, or Cerebrovascular Disorder; Epileptic Confusional State, Twilight State
293.1 - Subacute Delirium; Confusional State; Infective Psychosis; Organic Reaction; Posttraumatic Organic Psychosis; Psycho-organic Syndrome; Psychosis Associated with Endocrine or Metabolic Disorder
293.89 - Transient Mental Disorders Due to Conditions Classified Elsewhere, Other Specified; Catatonic Disorder in Conditions Classified Elsewhere
307 - Special Symptoms or Syndromes, Not Elsewhere Classified

Complications

Injury could result if the individual falls out of bed or gets entangled with intravenous lines or catheters. Medically ill individuals, especially the elderly, may have serious complications associated with delirium, including pneumonia and decubitus ulcers. These individuals may exhibit functional decline or the inability to attend to daily activities such as feeding, dressing, toileting, or hygiene, which may lead to institutional placement. Postoperative delirium is associated with increased risk for complications, longer postoperative recuperation, and increased risk of long-term disability. Older individuals who develop delirium during a hospitalization may have up to a 20% to 75% chance of dying during that hospitalization. Up to 25% of older individuals with delirium die within a 6-month period of discharge from the hospital.
