INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19042103. [PMID: 35206290 PMCID: PMC8872318 DOI: 10.3390/ijerph19042103] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 02/07/2022] [Accepted: 02/09/2022] [Indexed: 12/02/2022]
Abstract
Older people are increasingly dependent on others to support their daily activities due to geriatric symptoms such as dementia. Some of them stay in long-term care facilities. Elderly people with night wandering behaviour may lose their way, leading to a significant risk of injuries. The eNightLog system was developed to monitor the night-time bedside activities of older people in order to help them cope with this issue. It comprises a 3D time-of-flight near-infrared sensor and an ultra-wideband sensor for detecting human presence and to determine postures without a video camera. A threshold-based algorithm was developed to classify different activities, such as leaving the bed. The system is able to send alarm messages to caregivers if an elderly user performs undesirable activities. In this study, 17 sets of eNightLog systems were installed in an elderly hostel with 17 beds in 9 bedrooms. During the three-month field test, 26 older people with different periods of stay were included in the study. The accuracy, sensitivity and specificity of detecting non-assisted bed-leaving events was 99.8%, 100%, and 99.6%, respectively. There were only three false alarms out of 2762 bed-exiting events. Our results demonstrated that the eNightLog system is sufficiently accurate to be applied in the hostel environment. Machine learning with instance segmentation and online learning will enable the system to be used for widely different environments and people, with improvements to be made in future studies.

Abstract
Wandering is a common behavioral disorder in the community-dwelling elderly. More than two-thirds of caregivers believe that wandering would cause falls. While physical restraint is a common measure to address wandering, it could trigger challenging behavior in approximately 80% of the elderly with dementia. This study aims to develop a virtual restraint using a night monitoring system (eNightLog) to provide a safe environment for the elderly and mitigate the caregiver burden. The eNightLog system consisted of remote sensors, including a near infra-red 3D time-of-flight sensor and ultrawideband sensors. An alarm system was controlled by customized software and algorithm based on the respiration rate and body posture of the elderly. The performance of the eNightLog system was evaluated in both single and double bed settings by comparing to that of a pressure mat and an infrared fence system, under simulated bed-exiting scenarios. The accuracy and precision for the three systems were 99.0%, 98.8%, 85.9% and 99.2%, 97.8%, 78.6%, respectively. With higher accuracy, precision, and a lower false alarm rate, eNightLog demonstrated its potential as an alternative to physical restraint to remedy the workload of the caregivers and the psychological impact of the elderly.

Abstract
OBJECTIVES We sought to evaluate patient involvement (consultation and direct participation) in the assessment of alternative measures to restraint and seclusion among adults in short-term hospital wards (in psychiatry) and long-term care facilities for the elderly. METHODS We conducted individual semi-structured interviews with thirteen stakeholders: caregivers, healthcare managers, patient representatives, health technology assessment (HTA) unit members, researchers, and members of the local HTA scientific committee. Data were collected until saturation. We carried out content analysis of two HTA reports and four other documents that were produced in relation with this HTA. We also used field notes taken during formal meetings and informal discussions with stakeholders. We performed thematic analysis based on a framework for assessing patient involvement in HTA. We then triangulated data. RESULTS For the majority of interviewees, patient consultation enriched the content of the HTA report and its recommendations. This also made it possible to suggest other alternatives that could reduce the use of restraint and seclusion and helped confirm some views and comments from healthcare professionals consulted in this HTA. The direct participation of patient representatives enabled rephrasing of some findings so as to bring the patient perspective to the HTA report. CONCLUSIONS Patient consultation was seen as having directly influenced the content of the HTA report while direct participation made it possible to rephrase some findings. This is one of few studies to assess the impact of patient involvement in HTA and more such studies are needed to identify the best ways to improve the input of such involvement.

Abstract
Neurologists are commonly asked to make decisions concerning the use of physical restraints on hospitalized patients. These decisions are determined within the context of medical risk to the patient, including falls and the disruption of medical therapies (eg, self-extubation, removal of nasogastric tubes), risk to the caregivers, and the wishes of patients and their families. Familiarity with the medicolegal issues involved, including regulations of the local hospital and governmental agencies, as well as current evidence concerning the efficacy and harms that can occur with these interventions, is paramount to determining whether to use devices designed to restrict patients' freedom of movement in order to control their behavior.

Abstract
RÉSUMÉBien que la documentation américaine sur la réduction de l'usage des moyens de contention soit relativement importante, les travaux de recherche publiés sur cette même question sont moins nombreux sur les pensionnaires d'un établissement canadien de soins de longue durée. Les statistiques des plus importants établissements de ce type financés et exploités au Canada ont mis au jour des attitudes révélatrices envers les moyens mécaniques de contention. Durant les quatre années d'une étude comportant une campagne visant à réduire l'utilisation de moyens mécaniques de contention, la prévalence organisationnelle est passée de 24,68 % à 16,01 %. Il existait une variabilité substantielle en matière de contention parmi les 11 centres de l'organisation (échelle de 0 à 39,86 % des pensionnaires faisant l'objet de contention) et tous sauf un ont pu réduire la contention mécanique. Des facilitateurs particuliers à la réalisation et au maintien de la réduction de la contention sont indiqués, notamment les établissements de petite taille, la fourniture de soins spécialisés (par ex., maladie d'Alzheimer), et un «champion» résidant sur place. Des obstacles particuliers, comme la grande taille d'un établissement et un champion résidant à l'extérieur font aussi l'objet de discussion.

Abstract
This article reviews the problems with the implementation of evidence-based care in long-term care. It highlights the fact that many common practices are incompatible with evidence and that available evidence, including evidence about inadvisable and ineffective treatments, is often not followed. Often, there is a tendency to follow recommendations for younger persons (for example, the management of hypertension and elevated cholesterol), or to use questionable interventions (for example, choices for treating constipation). In many cases, the treatments used have only marginal efficacy and increased potential for side effects. This article makes recommendations for improving the approach to evidence-based care in long-term care and strongly urges the FDA to require drug studies in nursing homes.

Abstract
Background To date, the literature has provided an abundance of evidence on the adverse outcomes of restraint use on patients. Reportedly, nurses are often the personnel who initiate restraint use and attribute its use to ensuring the safety of the restrained and the others. A clinical trial using staff education and administrative input as the key components of a restraint reduction program was conducted in a rehabilitation setting to examine whether there were any significant differences in the prevalence of restraint use pre- and post-intervention. Subsequent to the implementation of the intervention program, focus group interviews were conducted to determine the perspective of the nursing staff on the use of restraints and their opinions of appropriate means to reduce their use. Method Registered nurses working in units involved in the study were invited to participate in focus group interviews on a voluntary basis. Twenty-two registered nurses (three males [13.6%] and nineteen females [86.4%]) attended the four sessions. All interviews were audio taped and transcribed verbatim. Other than the author, another member of the project team validated the findings from the data analysis. Results Four themes were identified. Participants experienced internal conflicts when applying physical restraints and were ambivalent about their use, but they would use restraints nonetheless, mainly to prevent falls and injuries to patients. They felt that nurse staffing was inadequate and that they were doing the best they could. They experienced pressure from the management level and would have liked better support. Communication among the various stakeholders was a problem. Each party may have a different notion about what constitutes a restraint and how it can be safely used, adding further weight to the burden shouldered by staff. Conclusion Studies about restraints and restraint use have mostly focused on nurses' inadequate and often inaccurate knowledge about the use of restraints and its associated adverse effects. These studies, however, fail to note that nurses can also be victims of the system. Restraint use is a complex issue that needs to be understood in relation to the dynamics within an environment.

Abstract
OBJECTIVES The objectives of this study were to evaluate the prevalence of potential elder abuse among older adults receiving home care and to assess the association between behavioral symptoms and potential abuse. METHODS Data on 4,630 subjects aged 65 or older receiving home care in Italy were collected using the Minimum Data Set for Home Care assessment. Potential abuse included signs of physical or emotional abuse and neglect. Behavioral symptoms were present if the participant exhibited one or more of the following symptoms in the 3 days before the assessment: wandering, verbally abusive, physically abusive, socially inappropriate behavior, and active resistance to care. RESULTS Mean age of participants was 80.5 years (standard deviation: 7.7) and 2,761 (60%) were female. Signs of potential abuse were identified in 336 of 3,869 (9%) participants without behavioral symptoms and 126 of 761 (17%) with behavioral symptoms. After adjustment for potential confounders, presence of behavioral symptoms was significantly associated with potential abuse (odds ratio [OR]: 1.56; 95% confidence interval [CI]: 1.21-2.00). Examining behavioral symptoms separately, wandering was negatively associated with potential abuse (OR: 0.58; 95% CI: 0.36-0.97), whereas other symptoms were positively associated with this outcome (verbally abusive behavior OR: 1.69, 95% CI: 1.24-2.31; physically abusive behavior OR: 1.42, 95% CI: 1.00-2.03; socially inappropriate behavior OR: 1.78, 95% CI: 1.26-2.53; active resistance of care OR: 1.69, 95% CI: 1.20-2.38). CONCLUSION Signs of potential abuse are common among older adults in home care in Italy and they are associated with the presence of behavioral symptoms.

Abstract
The increase in prevalence of obesity in older individuals and the association of obesity with increased morbidity, functional decline, hospitalization, and complications is expected to increase the number of individuals who have obesity requiring nursing home care, particularly subacute and short-term rehabilitation. Providing appropriate nursing home care to residents who have obesity requires environmental modifications, specialized equipment, and staff training. Effective nursing home care of residents who have obesity is interdisciplinary and requires special nursing, medical, nutritional, psychosocial, and rehabilitation considerations.

Abstract
The use of physical restraints in the elderly is a common practice in many countries. This paper summarizes the current knowledge on the use of restraints in home care, hospitals and nursing homes. Between 1999-2004 the reported prevalence numbers range from 41-64% in nursing homes and 33-68% in hospitals; numbers of restraint use in home care are unknown. Bed rails and belts have been reported as the most frequently used restraints in bed; chairs with a table and belts are the most frequently reported restraints in a chair. It is evident that physical restraints in most cases are used as safety measures; the main reason is the prevention of falls. In the hospital setting, the safe use of medical devices is also an important reason for restraint use. Predictors for the use of physical restraints are poor mobility, impaired cognitive status and high dependency of the elderly patient and the risk of falls in the nurses' opinion. Furthermore, there are indications that restraint use is related to organizational characteristics. Finally, many adverse effects of restraint use have been reported in the literature, like falls, pressure sores, depression, aggression, and death. Because of the adverse effects of restraints and the growing evidence that physical restraints are no adequate measure for the prevention of falls, measures for the reduction of physical restraints are discussed and recommendations are made for future research.
