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.

Factors Influencing Duration

The severity of the disease, the individual's response to treatment, any complications, and the presence of other illnesses may influence length of disability. Duration depends on comorbid conditions such as impaired immune system. Individuals with PCP are likely to have recurrences of the disease.

Medical Codes

ICD-9-CM:
136.3 - Pneumocystosis; Pneumonia Due to Pneumocystis carinii; Pneumonia Due to Pneumocystis jiroveci

Prognosis

Untreated Pneumocystis carinii pneumonia is a leading cause of death for individuals with AIDS. When respiratory failure occurs as a result of damage to the lungs, the chances of survival are low. Because of the various medical conditions associated with AIDS, it is difficult to assess survival rates for those with PCP, even when it has been treated. PCP often recurs, which increases the chance for complications and possible death.

When those with weakened immune systems are given preventive antibiotic treatment, the risks of serious or prolonged illness from PCP are greatly reduced. With preventative antibiotic use, the mortality rate from PCP is now 10% to 20% for individuals with AIDS, and up to 10% for individuals who have cancer or have had organ transplantation (Fernandes; Schreibman; Khan). Prophylactic antibiotic treatment of individuals receiving bone marrow transplantation has reduced the risk of PCP from 15% to less than 1% (Yen).
