Risk factors for recurrent injurious falls that require hospitalization for older adults with dementia: a population based study

Background: Older adults with dementia are at an increased risk of falls, however, little is known about risk factors for recurrent injurious falls (a subsequent fall after the first fall has occurred) among this group. This study aimed to identify risk factors for recurrent injurious falls requiring hospitalization among adults aged 60+ years with dementia. Methods: This retrospective, whole-population cohort study was conducted using the Western Australian Hospital Morbidity Data System and Western Australian Death Registrations from 2001 to 2013. Survival analysis using a stratified conditional Cox model (type 1) was undertaken to identify risk factors for recurrent injurious falls requiring hospitalization. Results: There were 32,519 participants with an index hospital admission with dementia during the study period. Over 27 % (n = 8970) of the cohort experienced a total of 11,073 injurious falls requiring hospitalization during follow up with 7297 individuals experiencing a single fall, 1330 experiencing two falls and 343 experiencing three or more falls. The median follow-up time for each individual was 2.49 years. Females were at a significantly increased risk of 7 % for recurrent injurious falls resulting in hospitalization (adjusted hazard ratio 1.07, 95 % CI 1.01–1.12), compared to males. Increasing age, living in rural areas, and having an injurious fall in the year prior to the index hospital admission with dementia also increased the risk of recurrent injurious falls resulting in hospitalization. Conclusions: Screening those with dementia for injurious falls history could help to identify those most at risk of recurrent injurious falls. Improvement of heath care an

Caregivers' experience of risk in dementia: The LASER-AD Study

The objective was to explore caregivers' experience of and concerns about the safety of care recipients (CRs) with Alzheimer's disease (AD) living at home. We interviewed family caregivers about their concerns regarding CR's safety, occurrence of risk over the last year and safety measures taken to manage risk. A total of 89 family caregiver/CR dyads participated. All had been recruited as part of a larger longitudinal study based in London and South East Region ( LASER) of the UK. Caregivers spent a substantial proportion of the day supervising the CR (mean = 15.5 hours). Most caregivers (39; 81.2%) of the 48/89 CRs left alone worried about their safety. Sixty-one (68.5%) caregivers reported at least one incident in which the CR had been at risk within the past year. A majority (71; 79.8%) had taken measures to prevent risk behaviours. Greater impairment in activities of daily living and the caregiver not being the CR's spouse were associated with more measures being taken. Caregivers themselves provide supervision most of the time for the CR, and are worried when they are left alone. This is realistic as despite caregiver's attempts at managing their CR's risks, including direct supervision, dangerous incidents still frequently occur in people with AD

An Update On Bone Substitutes For Spinal Fusion

With the current advances in spinal surgery, an understanding of the precise biological mechanism of each bone substitute is necessary for inducing successful spinal fusion. In this review, the categories of bone substitutes include allografts, ceramics, demineralized bone matrix, osteoinductive factors, autogenous platelet concentrate, mesenchymal stem cells, and gene therapy. Further, clinical studies have been evaluated by their levels of evidence in order to elucidate the precise effect of the bone substitute employed and to establish clinical guidance. This article will review both clinical studies based on evidence and basic research in current advances in order to avoid as far as possible any chances of failure in the future and to understand cellular biology in novel technologies.Wo
