Field Evaluations of Tracking/Locating Technologies for Prevention of Missing Incidents. - American journal of Alzheimer's disease and other dementias
Persons with dementia are at risk of a missing incident, which is defined as an instance in which a demented person's whereabouts are unknown to the caregiver and the individual is not in an expected location. Since it is critical to determine the missing person's location as quickly as possible, we evaluated whether commercially available tracking technologies can assist in a rapid recovery.This study examined 7 commercially available tracking devices: 3 radio frequency (RF) based and 4 global positioning system (GPS) based, employing realistic tracking scenarios. Outcome measures were time to discovery and degree of deviation from a straight intercept course.Across all scenarios tested, GPS devices were found to be approximately twice as efficient as the RF devices in locating a "missing person." While the RF devices showed reasonable performance at close proximity, the GPS devices were found to be more appropriate overall for tracking/locating missing persons over unknown and larger distances.© The Author(s) 2016.
Sociotechnical probabilistic risk modeling to predict injurious falls in community living centers. - Journal of rehabilitation research and development
The goal of this study was to apply sociotechnical probabilistic risk assessment to prioritize risks and prevention strategies for serious injurious falls of residents in nursing homes. Risk modeling teams consisted of 26 clinical and nonclinical staff from three Department of Veterans Affairs community living centers and one state Veteran's nursing home. Participants met in groups several times to identify and assign probabilities to provider and resident at-risk behaviors and equipment failures. They identified prevention strategies for the failures that accounted for the highest levels of risk. Six scenarios were modeled: (1) transferring from bed to wheelchair, (2) propelling from bedside to bathroom, (3) transferring from wheelchair to toilet, (4) transferring from toilet to wheelchair, (5) propelling from bathroom to bedside, and (6) transferring from wheelchair to bed. The greatest paths of risk were for residents with impaired mobility and high fragility. A 26% reduction in injurious falls could be achieved by (1) reducing the number of unassisted transfers through a modest improvement in response time to alarms, (2) installing automatic brake locks on 90% of wheelchairs, (3) making the wheelchair maintenance process highly reliable, and (4) decreasing improper transfer techniques by 10%.
Reducing Falls and Fall-Related Injuries in Medical-Surgical Units: One-Year Multihospital Falls Collaborative. - Journal of nursing care quality
On the basis of fall injury program characteristics across multiple inpatient medical-surgical units from 6 medical centers, we developed and implemented an operational strategic plan to address fall and injury prevention program attributes and enhance program infrastructure and capacity. Expert faculty provided lectures and served as coaches and mentors through triweekly conference calls and collaborative e-mail exchange. Statistically significant findings support improved fall and injury prevention program components and processes at the organizational and unit levels.
The Concept of Missing Incidents in Persons with Dementia. - Healthcare (Basel, Switzerland)
Behavioral symptoms of dementia often present the greatest challenge for informal caregivers. One behavior, that is a constant concern for caregivers, is the person with dementia leaving a designated area such that their whereabouts become unknown to the caregiver or a missing incident. Based on an extensive literature review and published findings of their own research, members of the International Consortium on Wandering and Missing Incidents constructed a preliminary missing incidents model. Examining the evidence base, specific factors within each category of the model were further described, reviewed and modified until consensus was reached regarding the final model. The model begins to explain in particular the variety of antecedents that are related to missing incidents. The model presented in this paper is designed to be heuristic and may be used to stimulate discussion and the development of effective preventative and response strategies for missing incidents among persons with dementia.
Exercise interventions, gait, and balance in older subjects with distal symmetric polyneuropathy: a three-group randomized clinical trial. - American journal of physical medicine & rehabilitation
Older patients with a distal symmetric polyneuropathy are at markedly increase risk for falls and fall-related injuries. Despite this, few studies have investigated the effect of exercise regimens on gait and balance in this high-risk group.One hundred older patients with distal symmetric polyneuropathy were randomized to one of three interventions: functional balance training, Tai Chi, or education-only control. The subjects in each group received instruction in ten 1-hr weekly sessions. Outcome measures were determined at baseline and the end of the 10-wk intervention. Gait, balance, and falls self-efficacy were assessed with various well established clinical (Berg Balance Scale, 8 Foot Up and Go Test, and Modified Falls Efficacy Scale) and laboratory-based measures (three-dimensional gait analysis and NeuroCom limits of stability and sensory organization tests).The Tai Chi subjects demonstrated a decreased (faster) Timed Up and Go and increased stride length and time spent in single limb support at the end of intervention as compared with baseline. The functional balance training group demonstrated a significant increase in ankle plantar flexor power and near significant decreases in step width and step width variability. No changes in the education-only control group were observed.Older patients with distal symmetric polyneuropathy may benefit from Tai Chi and/or functional balance training, with the former improving functional mobility and gait and the latter possibly improving trunk stabilization and forward progression (Lythgo N, Cofré LE: Relationship between ankle plantar flexor power and EMG muscle activity during gait. 30th Annual Conference of Biomechanics in Sports [Melbourne, 2012]. Available at: https://ojs.ub.uni-konstanz.de/cap/article/viewFile/5320/4891). Whether these laudable changes can be maintained or translate into decreased risk for falls and fall-related injuries is unknown.
Reducing falls and fall-related injuries in mental health: a 1-year multihospital falls collaborative. - Journal of nursing care quality
Despite much research on falls occurring on medical-surgical units and in long-term care settings, falls on inpatient psychiatry units are understudied. On the basis of fall injury program characteristics across multiple inpatient psychiatry units, we developed and implemented an operational strategic plan to address each falls prevention program element and enhance program infrastructure and capacity. Expert faculty provided lectures, coaching, and mentoring through biweekly conference calls and collaborative e-mail exchange. Findings support continued efforts to integrate measures to reduce serious fall-related injuries.
Effects of step length, age, and fall history on hip and knee kinetics and knee co-contraction during the maximum step length test. - Clinical biomechanics (Bristol, Avon)
Maximum step length is a brief clinical test involving stepping out and back as far as possible with the arms folded across the chest. This test has been shown to predict fall risk, but the biomechanics of this test are not fully understood. Knee and hip kinetics (moments and powers) are greater for longer steps and for younger subjects, but younger subjects also step farther.To separate the effects of step length, age, and fall history on joint kinetics; healthy younger (age=27(5), N=14), older non-fallers (age=72(5), N=14), and older fallers (age=75(6), N=11) all stepped to the same relative target distances of 20-80% of their height. Knee and hip kinetics and knee co-contraction were calculated.Hip and knee kinetics and knee co-contraction all increased with step length, but older non-fallers and fallers utilized greater stepping hip and less stepping knee extensor kinetics. Fallers had greater stepping knee co-contraction than non-fallers. Stance knee co-contraction of non-fallers was similar to young for shorter steps and similar to fallers for longer steps.Age had minimal effects and fall history had no effects on joint kinetics of steps to similar distances. Effects of age and fall history on knee co-contraction may contribute to age-related kinetic differences and shorter maximal step lengths of older non-fallers and fallers, but step length correlated with every variable tested. Thus, declines in maximum step length could indicate declines in hip and knee extensor kinetics and impaired performance on similar tasks like recovering from a trip.© 2013.
Safe home program: a suite of technologies to support extended home care of persons with dementia. - American journal of Alzheimer's disease and other dementias
To report the implementation/adoption of the Safe Home Program to support caregivers of persons with dementia in (1) ongoing surveillance, (2) provision of care, (3) prevention of injuries, and (4) improving home safety.For this demonstration project 4 assessment questionnaires (Safety Assessment Scale, Vigilance Scale, Peace of Mind Scale, and Sleep Disorders Inventory) were administered to each dyad to understand their technological needs. After identification and installation of appropriate technologies and education of the caregiver, a final visit (at 3 months) determined whether technologies were useful and being used.The majority of caregivers utilized technologies for ongoing surveillance; other technologies included an identification program and medication organizer.Technologies focused on ongoing surveillance for persons with dementia at the home are needed. These technologies could be quickly adopted by caregivers to ameliorate some of the stress and burden associated with providing care for persons with dementia.
Influence of a transitional care clinic on subsequent 30-day hospitalizations and emergency department visits in individuals discharged from a skilled nursing facility. - Journal of the American Geriatrics Society
To evaluate an intervention to improve care transitions at the time of skilled nursing facility (SNF) discharge.Natural experiment using a pre-post design.Veterans Affairs hospital, community SNF, and outpatient clinic.The pre-intervention group comprised 134 individuals discharged to the community from posthospitalization SNF care, and the intervention group was 217 individuals who received a postdischarge clinic (PDC) intervention at SNF discharge after receiving posthospitalization care at the SNF.This study is a natural experiment using a pre-post design. The intervention was a one-time visit to a PDC before SNF discharge, where an advanced nurse practitioner conducted medication reconciliation, ordered medical supplies and equipment and home health services if needed, provided individual and caregiver education, and communicated the information to the individual's primary outpatient care provider through electronic medical records.The pre-PDC and PDC intervention groups were compared on various measures of hospital utilization within 30 days of the SNF discharge (number of rehospitalizations, acute care inpatient days, and emergency department (ED) visits).Although there was a 23% rehospitalization rate in the pre-PDC group, participants in the PDC intervention group had a 14% rehospitalization rate within 30 days of SNF discharge (P = .02). Those who received the PDC intervention had significantly fewer acute care inpatient days during the 30-day follow-up (P < .001). Although the difference in the number of ED visits between the two groups was not statistically significant, the number of ED visits per 1,000 patient follow-up days during the 30-day interval was significantly lower in the PDC intervention group (P = .03).Comprehensive care coordination at the time of SNF discharge can reduce postdischarge hospital use in settings with shared electronic records.© 2012, Copyright the Authors Journal compilation © 2012, The American Geriatrics Society.
Training implications of maximal forces on a computer-controlled and motor-driven leg press by age group, sex, footplate direction, and speed. - Experimental gerontology
Strength training that overloads lengthening muscle fibers may result in greater strength gains with less effort and perceived exertion than conventional training modalities. This study evaluates a device capable of this overloading (a motor-driven and computer-controlled leg press) to develop recommendations for future training interventions. Unimpaired younger and older men and women (7/group, total n=28) performed three maximal-effort trials for both directions of footplate motion (IN and OUT) at three speed profiles (knee rotation speeds of 15, 25, and 35°/s) on a motor-driven and computer-controlled leg press. Normalized forces were tested for effects of age group, sex, direction of footplate motion, and knee rotation speed. Peak forces were 57% greater for younger and 20% greater for IN. Trends of greater IN relative to OUT forces (IN overloading) were present in women, but this was due to an inverse correlation between strength and IN overloading that was independent of age group and sex. Leg press strength training on a device that is capable of overloading lengthening muscle fibers is a promising new training method that appears to have the greatest potential benefits for the weakest participants. Training target profiles on the device tested and others similar to it should be set based on participant-specific maximums across the ROM in both IN and OUT directions at a speed in the middle of the range to be trained.Published by Elsevier Inc.
