Aims: This study was undertaken to estimate the effect of hip protectors on the incidence of hip fracture when introduced into nursing homes as a regular part of the healthcare for all residents. Methods: A pre-test/test design was used. The pre-intervention period lasted 18 months from May 1996. The intervention period lasted 18 months from May 1998. During the intervention period all residents (965 beds) in nursing homes in two municipalities in Norway were offered free use of hip protectors. The project manager provided motivational activities in the nursing homes during the whole period, aimed at increasing the participation rate. Results: The intervention period showed a 39% reduction in the hip fracture incidence when compared with the pre-intervention period (p=0.003). The percentage of daily users of the protector varied from 35% during the first months to 22% at the end of the period. Among the 61 persons who suffered a hip fracture 31 were registered as daily users. Fourteen of the 31 users were not wearing the protector when the hip fracture occurred, while five of the 31 had the protector on their knees. Twelve of the 31 suffered a hip fracture while properly wearing the protector. Conclusions: This non-randomized study showed that hip protectors introduced to all residents in nursing homes considerably reduced the incidence of hip fracture. It may be possible to achieve higher compliance and a further reduction in the incidence of hip fractures if the producers of hip protectors increase the comfort of the protector without reducing its effect. In addition, it is important that health workers encourage more individuals at high risk to use the protector.

Key Words: accidental falls • frail elderly • hip fractures • patient compliance • protective clothing (hip protectors).
