Most of the outcome question naires had a mixed content reflecting various constructs such as pain and symptoms , sleep disturbances , psychological dysfunctions , physical impairments , and social functions .
STUDY DESIGN A systematic literature review of outcome question naires design ed for assessing functional status or disability in patients with low back pain .
OBJECTIVES To provide a comprehensive overview of all functioning/disability question naires used in recent years and to explore how the main concept(s ) was described or defined in the original paper , the content or the domains of disability , and the measurement properties of the question naires .
SUMMARY OF BACKGROUND DATA A number of clinical tools design ed for evaluating the functional status of patients with low back pain have been developed .
Only a few have been review ed earlier , and there has been little focus on the content reflected in the question naires .
Predictors of time loss after back injury in nurses.
STUDY DESIGN A 2-year prospect i ve inception cohort study of back injury in nurses . OBJECTIVES To determine the extent to which characteristics of nurses , of the injury , and of the workplace predict occurrence and duration of time loss from work after back injury . SUMMARY OF BACKGROUND DATA During 2 years , 320 nurses incurred 416 back injuries at a large teaching hospital in Winnipeg , Canada . Nurses injured on preselected wards were targeted for early intervention , including provision of modified work , whereas nurses injured on other wards received the usual care . METHODS Time loss attributable to the back injury during the 6 months after injury was analyzed . Three statistical models were used to examine occurrence of time loss ( logistic regression ) , duration of time loss ( Tobit regression ) , and duration of time loss once an injury incurring time loss had been documented ( least-squares regression ) . RESULTS In 218 of the 416 injuries , the injured nurse consented to interview . Whereas perceived disability was related to whether a time loss injury would ensue , self-reported pain was strongly related to the duration of time loss once an injury had become a time loss injury . Duration of time loss was reduced by participation in the return-to-work program . Mechanism of injury , specifically injury occurring while lifting patients , result ed in greater time loss . CONCLUSIONS Focusing on reducing the perception of disability at the time of injury is critical to preventing time loss , but once time loss has occurred , offer of modified work and attention to pain reduction are warranted . The findings add to the evidence that workplace-based intervention programs can be effective in reducing the morbidity result ing from back injury
