A research proposal testing a new model of ambulation activity among long-term care residents with dementia/cognitive impairment: the study protocol of a prospective longitudinal natural history study
Abstract:Background
Excessive and patterned ambulation is associated with falls, urinary tract infections, co-occurring delirium and other acute events among long-term care residents with cognitive impairment/dementia. This study will test a predictive longitudinal data model that may lead to the preservation of function of this vulnerable population.
Methods/design
This is a single group, longitudinal study with natural observations. Data from a real-time locating system (RTLS)… Show more
“…The independent variable of interest in this study is motor behavior, calculated using the x - and y -coordinates provided by the real-time locating system (RTLS, Ubisense series 7000 IP Sensor, and Series 700 Tag) with ultra-wideband radio frequency identification, UWB RFID technology (Ubisense, 2021). Previous work details the protocol, measures, and benefits of using a real-time objective and continuous measuring system in health care (Bowen, 2020; Bowen, Kearns, et al, 2019; Bowen, Rowe, et al, 2019). Briefly, participants wore an RTLS tag on their wrist continuously (24/7) at update rates of up to 6 times/s.…”

“…This longitudinal natural history study aims to examine how changes in motor behavior (using RTLS) may be an early indicator of a fall, delirium, and/or UTI. The RTLS used here is an objective and continuous (e.g., 24/7) wrist-worn sensor that measures multiple residents’ location and movement simultaneously around the unit with an accuracy of 6 cm (Bowen, Kearns, et al, 2019; Bowen, Rowe, et al, 2019; Bowen et al, 2013). It is expected that intra-individual changes in motor behavior (distance traveled, gait speed, and path characteristics (continuous walking with little/no breaks) will be associated with acute events.…”

This study aimed to examine how changes in motor behavior are associated with falls, delirium, and urinary tract infections (UTIs). Twenty-three (128 observations) skilled nursing residents were examined for up to 18 months. In multilevel models, motor behaviors (e.g., time and distance traveled, gait speed), measured by a real-time locating system, were used to predict falls, UTIs, and delirium. Falls were associated with decreased gait speed ( OR = 0.01; p ≤ 0.001) and path distance ( OR = 0.99; p ≤ 0.05); delirium was associated with increased distance traveled ( OR = 1.01; p ≤ 0.001), path distance ( OR = 1.02; p ≤ 0.001), and decreased time traveled ( OR = 0.99; p ≤ 0.001) and path time ( OR = 0.99; p ≤ 0.001); UTIs were associated with increased distance traveled ( OR = 1.01; p ≤ 0.001), decreased time traveled ( OR = 0.99; p ≤ 0.001), and the number of paths ( OR = 0.91; p ≤ 0.01). Subtle changes in motor behavior may be an early warning sign of falls and acute events. Continuous monitoring may enable clinical staff to prevent, identify early, and/or delay these poor health outcomes.
