Work Intensity During Working Hours and Different Types of Care Done by Special Nursing Home Workers

: This study was done to estimated work intensity during working hours and different types of care to obtain basic data for making a care program. The subjects were care workers in good health (n = 8, 24-45 years) who worked in a special nursing home. The estimated maximal oxygen intake level, which is the maximal aerobic capacity, of each subject was assessed as normal to very good. The energy expenditure was 1787 +/- 534kcal during working hours. The work intensity was 0.061 +/- 0.011kcal/kg/min, 2.7 +/- 0.7RMR, 98 +/- 6beats/min, and 30.3 +/- 2.0% VO2max. Among the duties assessed for work intensity, bathing had the highest intensity, followed by transferring, changing diapers, feeding, and dressing. The work intensity of bathing was 0.081 +/- 0.31kcal/kg/min, 3.9 +/- 1.0RMR, and 40.0 +/- 6.1 VO2 max, which was significantly higher than feeding, dressing, and transferring(p < 0.05). Care giving at the time of bathing was significantly longer than the other care types (p < 0.05). Feeding and transferring by inexperienced care workers were significantly low intensity (p < 0.05). Work intensity of care was at high levels within the maximal permissible level in which fatigue doesn't make an appearance during working hours and in five types of care. Furthermore, care work intensity increased according to a decrease in the ADL level among the elderly. It is concluded that when making a care program, it is important to consider the ADL level of the elderly, work intensity and the amount of care-giving time, not only to maintain the health of care workers, but, also, to give superior quality care to the elderly.
