A pilot study was carried out to determine the effects of hospital bed height cycle time and bed height control location upon the incidence rates of low back injury (LBI) among nursing personnel at three hospitals. These hospitals included facility-A, a Veterans Administration (VA) medical center having 66 acute care beds, 126 extended care beds, and an average of 184 full time equivalent (FTE) nursing service employees; facility-B, a VA medical center having 216 acute care beds, no extended care beds, and an average of 146 FTE nursing service employees; and facility-C, a state operated medical center having 452 acute care beds, no extended care beds, and an average of 803 FET nursing service employees. Annual LBI incidence rates for the years 1984 through 1986 for each hospital and for their medical/surgical and psychiatric wards were determined by calculating the rate of LBI in nursing service per 100 FET hospital nursing service employees and the rate of LBI on nursing ward per 100 FTE ward nursing employees, respectively. The ratio of incidence rate in a ward to incidence rate in a hospital was utilized as the dependent variable for analyses, whereas bed height high/low cycle times (BHCT) and locations of bed controls were used as independent variables. Facility-A, with an average BHCT of 38 seconds and controls located at the foot of the bed, showed the highest LBI incidence ratio, 2.3, in regard to both independent variables. Suggested guidelines were given for hospital bed design and control location. The author concludes that a hospital bed with a BHCT of approximately 20 seconds and controls located on the bed side frame or siderail may be most useful for encouraging nursing personnel to make proper use of hospital bed design and control characteristics.
