    Enhancing safety in the ischaemic and haemorrhagic stroke population: exploring the efficacy of self-releasing chair alarm belts
    Weppner, Justin; Gee, Alaric; Mesina, Kevin (BMJ, 2024-02-21)
    Introduction A quality improvement study evaluated the effectiveness of implementing self-releasing chair alarm belts in an inpatient rehabilitation facility (IRF) for patients who had a stroke. The objective of this study is to assess the effectiveness of self-releasing chair alarms as a chair-level fall preventive tool in patients who had a stroke in the IRF setting. Methods A preintervention and postintervention quality improvement study was conducted in an IRF to address the high rate of falls in the stroke population. Falls from wheelchairs were identified as a significant concern, leading to the implementation of self-releasing safety belts (Posey HeadStart Notification Sensor Belts) with alarm systems as an intervention. In the preintervention phase (July 2021 to January 2022) falls from chairs while on standard fall precautions were recorded to establish a baseline. In the intervention phase, the self-releasing chair alarm belts were introduced along with standard fall precautions. The postintervention phase spanned from February 2022 to July 2022. Results In the preintervention phase, 20 out of 86 stroke subjects experienced a total of 30 falls from chairs. However, in the postintervention phase, only one subject experienced a fall from a chair out of 104 stroke subjects. The mean percentage of subjects involved in falls decreased from 24±11.4% to 1±0.4% (p<0.00001), and the mean fall rate per 1000 patient days declined from 4.6±2 to 0.2±0.1 (p<0.0001). Conclusions The implementation of self-releasing chair alarm belts significantly reduced falls from chairs among patients who had a stroke in the IRF setting. These findings highlight the effectiveness of this intervention in improving patient safety and fall prevention in IRFs.

    Impact of Post-Traumatic Epilepsy on Mental Health and Multidimensional Outcome and Quality of Life: An NIDILRR TBIMS Study

    Traumatic brain injury (TBI) and subsequent post-traumatic epilepsy (PTE) often impair daily activities and mental health (MH), which contribute to long-term TBI-related disability. PTE also affects driving capacity, which impacts functional independence, community participation, and satisfaction with life (SWL). However, studies evaluating the collective impact of PTE on multidimensional outcomes are lacking. Thus, we generated a model to investigate how PTE after moderate-to-severe (ms)TBI affects TBI-associated impairments, limits activities and participation, and influences SWL. Of 5108 participants with msTBI enrolled into the National Institute for Disability, Independent Living, and Rehabilitation Research TBI Model Systems between 2010 and 2018 and with seizure-event data available at year-1 post-TBI, 1214 had complete outcome data and 1003 had complete covariate data used for analysis. We constructed a conceptual framework illustrating hypothesized interrelationships between year-1 PTE, driving status, functional independence measure (FIM), depression and anxiety, as well as year-2 participation, and SWL. We performed univariate and multivariable linear and logistic regressions. A covariate-adjusted structural equation model (SEM), using the lavaan package (R), assessed the conceptual framework’s suitability in establishing PTE links with outcomes 1-2 years post-injury. Multiple parameters were evaluated to assess SEM fit. Year-1 PTE was correlated with year-1 FIM motor (standardized coefficient, βstd = −0.112, p = 0.007) and showed a trend level association with year-1 FIM cognition (βstd = −0.070, p = 0.079). Individuals with year-1 PTE were less likely to drive independently at year 1 (βstd = −0.148, p < 0.001). In addition, FIM motor (βstd = 0.323, p < 0.001), FIM cognition (βstd = 0.181, p = 0.012), and anxiety (βstd = −0.135, p = 0.024) influenced driving status. FIM cognition was associated with year-1 depression (βstd = 0.386, p < 0.001) and year-1 anxiety (βstd = 0.396, p < 0.001), whereas year-1 FIM motor (βstd = 0.186, p = 0.003), depression (βstd = −0.322, p = 0.011), and driving status (βstd = 0.233, p < 0.001) directly affected year-2 objective life participation metrics. Moreover, year-1 depression (βstd = −0.382, p = 0.001) and year-2 participation (βstd = 0.160, p < 0.001) had direct effects on year-2 SWL. SWL was influenced indirectly by year-1 variables, including functional impairment, anxiety, and driving status—factors that impacted year-2 participation directly or indirectly, and consequently year-2 SWL, forming a complex relationship with year-1 PTE. A sensitivity analysis SEM showed that the number of MH disorders was associated with participation and SWL (p < 0.001), and this combined MH variable was directly related to driving status (p < 0.02). Developing PTE during year-1 after msTBI affects multiple aspects of life. PTE effects extend to motor and cognitive abilities, driving capabilities, and indirectly, to life participation and overall SWL. The implications underscore the crucial need for effective PTE management strategies during the first year post-TBI to minimize the adverse impact on factors influencing multidimensional year-2 participation and SWL outcomes. Addressing transportation barriers is warranted to enhance the well-being of those with PTE and msTBI, emphasizing a holistic approach. Further research is recommended for SEM validation studies, including testing causal inference pathways that might inform future prevention and treatment trials.
