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.

Medical Codes

ICD-9-CM:
599.0 - Urinary Tract Infection, Site Not Specified; Pyuria

Overview

Pyuria is the presence of white blood cells (leukocytes) in the urine (6 to 10 or more neutrophils per high power field of unspun, voided mid-stream urine). Pyuria is not a diagnosis; it is a laboratory finding in many diseases, most commonly urinary tract infections (UTI). Pyuria usually indicates that bacteria have invaded the upper or lower urinary tract, invoking an inflammatory response of the lining of the urinary tract (urothelium) in that location. When pyuria occurs secondary to UTI, it is usually accompanied by bacteriuria (bacteria in the urine). Pyuria may also be found in the absence of infection (sterile pyuria) and is frequently asymptomatic. When pyuria lacks the presence of bacteria, its cause is unclear, although "silent" or unrecognized kidney infection may be suspected as well as tuberculosis, renal stones, Kawasaki disease, or cancer. Almost half of chronically incontinent individuals or those with indwelling catheters (primarily elderly long-term care patients), exhibit asymptomatic pyuria. However, urinary tract infection can also be asymptomatic in the elderly. In the absence of infection, asymptomatic pyuria is not usually treated.

Incidence and Prevalence: Urinary tract infection (UTI) is the most common bacterial infection found in people of all ages (Foxman). Consequently, the incidence of pyuria corresponds to the large numbers of people diagnosed with UTI, which is far more common among women than men under the age of 70 and increases in both men and women as they age. Among the elderly, the rate of UTI is only slightly higher among women compared to men (Foxman).

The overall prevalence of asymptomatic infection among the general population is estimated at 3.5%, and the prevalence increases with age in a linear trend. Other risk factors for asymptomatic infection include parity, diabetes in women, a history of UTI, and lower education. An estimated 4% to 10% of pregnant women are diagnosed with asymptomatic UTI (Foxman).
