BackgroundPublished evaluations of successful interventions to prevent falls in people with sight impairment (SI) are limited. The aim of this feasibility study is to optimise the design and investigation of home safety (HS) and home exercise (HE) programmes to prevent falls in older people with SI.MethodsA community-based feasibility study in north-west England comprising a three-arm randomised controlled trial (RCT) allocated participants to (1) a control group receiving usual care and social visits, (2) an experimental group receiving the HS programme and (3) an experimental group receiving the HS + HE programme. Participants were community-dwelling, aged 65 years and older and sight impaired. Primary outcome data on falls were collected continuously over 6 months. Secondary outcomes on physical activity (self-report and instrumented) and adherence were collected at baseline and 3 and 6 months for HE and at 6 months for the HS programme. Costs for the HS and HS + HE groups were calculated from logs of time spent on home visits, telephone calls and travel. The research assistant and statistician were blinded to group allocation.ResultsAltogether, 49 people were recruited over a 9-month period (randomised: 16 to control, 16 to HS, 17 to HS + HE). The interventions were implemented over 6 months by an occupational therapist at a cost per person (pounds sterling, 2011) of £249 (HS) and £674 (HS + HE). Eighty-eight percent (43/49) completed the trial and 6-month follow-up. At 6-month follow-up, 100 % reported partially or completely adhering to HS recommendations but evidence for adherence to HE was equivocal. Although self-reported physical activity increased, instrumented monitoring showed a decrease in walking activity. There were no statistically significant differences in falls between the groups; however, the study was not powered to detect a difference.ConclusionIt is feasible and acceptable for an occupational therapist to deliver HS and HE falls prevention programmes to people with SI living independently in the community. Future studies could access Local Authority Registers of people with SI to improve recruitment rates. Further research is required to identify how to improve adherence to HE and to measure changes in physical activity before conducting a definitive RCT.Trial registrationISRCTN53433311, registered on 8 May 2014.
This article describes longitudinally the psychosocial adjustment to visual impairment of patients with age related macular degeneration (AMD). As part of a larger randomized controlled trial (RCT), the present study design consisted of the use of prospective qualitative diaries completed over 12 months by patients with AMD who were newly referred to a low vision clinic. Out of the patients recruited (n = 226), the completion rate of a full set of four diaries (n = 37) and one three-month diary (n = 194) was very good. Vision related to daily life in patients with AMD appears to decline over 12 months with limited psychosocial adjustment to visual loss. Seven themes were generated from the patients' accounts of their experiences, as recorded in the diaries: safety, loss of independence, isolation, support mechanisms, mood, effects of the media and psychosocial adjustment. There was little evidence in the diaries of psychosocial adjustment to visual loss. The relevance of the theory of grieving and cognitive and rational-emotional theory in the context of AMD is explored in detail.
BackgroundSight impairment increases with age and, compared with the general older population, older people with sight impairment are more likely to fall. There is a growing body of evidence on the views and perceptions of older people about falls, but little is published on the views of older people with sight impairment.ObjectiveTo explore what older people with sight impairment believe to be the causes of falls.DesignA qualitative design was used, incorporating focus groups and interviews in which participants discussed falls and falls prevention. Framework analysis was employed to identify themes arising from participants' discussions of the causes of falls.Setting and participantsFifty‐four community dwelling men and women with sight impairment, aged 65 and over, were recruited from across Greater Manchester, UK.ResultsFive types of factors were identified that were believed to cause falls: (i) health issues and changes in balance caused by ageing; (ii) cognitive and behavioural factors; (iii) the impact of sight impairment on getting around the home; (iv) the impact of sight impairment on negotiating the environment away from home; and (v) unexplained falls.Discussion and conclusionsOlder people with sight impairment reported many researched risk factors previously identified by older people without sight impairment but also described many perceived risks unique to people with sight impairment. There are few interventions to prevent falls aimed at older people with sight impairment, and the results of this study allow further tailoring of such interventions based on views of older people with sight impairment.
