Taking inventory

The eighth annual Most Wired Survey and Benchmarking Study is ready for the taking. It's an opportunity to get a comprehensive view of your hospitals IT systems and see how you stack up against your peers.

The psychosocial functioning inventory

The derivation and psychometric analyses of a general purpose outcome/survey instrument--the Psychosocial Functioning Inventory (PFI)--are described. The instrument contains scales designed to measure a wide array of constructs, including subjective well-being, social functioning, stressful events, treatment dependency/aftercare, and consumer satisfaction. Extensive reliability and validity analyses are reported, indicating reasonable reliability and validity for the PFI scales.     

Physiological limits in lifting

Two different experiments were conducted to study the effects of frequency, height and load of lift on computed maximal oxygen uptake and to compare the data obtained to a standard bicycle ergometer. A progressive submaximal technique was used to predict maximal oxygen uptake. The results of the present study revealed that across all heights, an increase in either the frequency of lift or load of lift was accompanied by an increase in computed maximal oxygen uptake; however, all maximal oxygen uptake values reported showed a tendency to level off beyond the frequency of five lifts/min. The results also showed that combined arm and leg lifting recorded the highest maximal oxygen uptake followed by leg lifting then arm lifting, respectively. Maximal oxygen uptake values obtained for lifting tasks were much lower than those obtained for a bicycle ergometer. It is therefore recommended that limits for continuous work for a lifting task be based on the attainable maximal oxygen uptake for that particular task and not on a maximal oxygen uptake obtained from another task such as a bicycle ergometer test.
