Objective To explore the application and effect of four-party (specialist nurse, community nurse, individual and family) co-nursing intervention, for fall prevention in community-dwelling elderly people at high risk of falls. Methods Two communities of Longgang District in Shenzhen were randomized into 2 groups, with 45 community-dwelling elderly people randomly selected from each community.The intervention group was subjected to four-party (specialist nurse, community nurse, individual and family) co-nursing intervention, while the control group to community-based routine care of fall-prevention.The 2 groups were measured with the Modified Falls Risk for Older People in the Community Screening Tool (MFROP-Com) and Tinetti Gait and Balance Test （TGBT） before, and at 12 months of the intervention. Incidence of falls in the two groups within a year was also compared. Results The incidence of falls in the intervention group was 1 count, versus 6 counts in the control group.The intervention group enjoyed an increase in TGBT scores （reflecting balance and gait ability）,and a decrease in MFROP-Com scores, both showing significant differences with the controls （P＜0.01 for all）. Conclusion The application of the four-party (specialist nurse, community nurse, individual and family) co-nursing intervention can effectively lower fall risks, improve anti-fall ability and prevent fall incidence in community-dwelling elderly people at high risk of falls.
