DESIGN: Randomised controlled trial. SETTING: Dunedin and Auckland, New Zealand. PARTICIPANTS: 391 women and men aged >/=75 with visual acuity of 6/24 or worse who were living in the community; 92% (361 of 391) completed one year of follow-up. INTERVENTIONS: Participants received a home safety assessment and modification programme delivered by an occupational therapist (n=100), an exercise programme prescribed at home by a physiotherapist plus vitamin D supplementation (n=97), both interventions (n=98), or social visits (n=96). Main outcome measures: Numbers of falls and injuries resulting from falls, costs of implementing the home safety programme. RESULTS: Fewer falls occurred in the group randomised to the home safety programme but not in the exercise programme (incidence rate ratios 0.59 (95% confidence interval 0.42 to 0.83) and 1.15 (0.82 to 1.61), respectively). However, within the exercise programme, stricter adherence was associated with fewer falls (P=0.001). A conservative analysis showed neither intervention was effective in reducing injuries from falls. Delivering the home safety programme cost $NZ650 ( pound234, 344 euros, $US432) (at 2004 prices) per fall prevented. CONCLUSION: The home safety programme reduced falls and was more cost effective than an exercise programme in this group of elderly people with poor vision. The Otago exercise programme with vitamin D supplementation was not effective in reducing falls or injuries in this group, possibly due to low levels of adherence.
