Evaluation of the effectiveness of the sliding sheet in repositioning care in terms of working time and subjective fatigue: A comparative study with an experimental design

Influence of caregiver understanding of their capability to perform activities of daily living, disease comprehension, and attitudes on occupational low back pain: a cross-sectional study

[Purpose] The aim in this study was to evaluate the impact of caregiver understanding of their ability to perform activities of daily living (ADLs), movement abilities, diseases, and attitudes on the prevalence of occupational low back pain. [Participants and Methods] A cross-sectional survey was conducted of caregivers of older adults living in residential care facilities. Of the 150 questionnaires distributed, 71 were valid. The survey collected data on demographics, low back pain status using a numerical rating scale, and familiarity with ten ADLs and five diseases (stroke, rheumatoid arthritis, fractures, Parkinson's disease, and dementia). [Results] In this study, 52% of the participants reported lower back pain. Significant factors included an understanding of repositioning in ADLs, familiarity with stroke and rheumatoid arthritis, and attitudes toward using patients' residual functions. Participants with limited knowledge of repositioning and stroke, a better understanding of rheumatoid arthritis, and those who did not consider residual function were more prone to lower back pain. [Conclusion] Our findings highlight the importance of enhancing caregiver education on ADL movements and disease specifics, particularly stroke and rheumatoid arthritis, and promoting the use of patients' residual capabilities. Improved training and information sharing among caregivers may reduce the risk of occupational low back pain.

Evaluation of repositioning care provided by non-professionals using a caregiver-assistive device: an experimental study

As the population ages in Japan and worldwide, the number of informal caregivers, such as family members, providing nursing care to older individuals is increasing. Among caregiving tasks, repositioning care, which causes lower back pain, is frequent and burdensome for caregivers. Therefore, we developed a position-changing device that can adjust and support the care recipient's body in the lateral position. This was a feasibility study of the device-assisted care provided by non-professionals using the device we developed. Of the 40 healthy volunteers enrolled, 17 simulated caregivers and 17 simulated care recipients finally participated in the study. One caregiver and one care recipient were paired to engage in two types of care: device-assisted care and manual care. Furthermore, the care provided by the caregiver and received by the care recipient were evaluated. Non-professionals were able to use the device successfully and safely after a short period of practice, and both caregivers and care recipients rated the device-assisted care positively. The study results suggest that informal caregivers can also provide safe and comfortable care that is less burdensome than manual care by using a caregiver-assistive device.

Effects of Slide Sheet Use and Bed Position on Muscle Activities in the Low Back and Extremities: A Pilot Experimental Simulation Study

BACKGROUND

Low-friction slide sheets (SS) are designed to reduce compression loads on the body during manual handling tasks, such as boosting patients. Using SS has been shown to decrease muscle activity in the lower back and upper extremities. However, it is unclear if this effect varies with different bed positions. To investigate this, we studied the effects of SS use, bed height, and their combination on muscle activity during a simulated patient boost.

METHODS

Thirty-three Japanese undergraduate students (age 21.0 ± 1.1 years; 14 men, 19 women) participated. Participants were asked to boost a dummy figure on the bed three times each using four conditions. During the repositioning task, electromyography of eight muscles of the lower back and upper and lower extremities, hip and knee joint flexion angles, pelvic forward tilt angle, and position of the center of mass based on the posterior superior iliac spine were evaluated.

FINDINGS

Electrophysiological activities of muscles of lower back and upper extremities were significantly lower with SS than without it in both bed positions (30% and 40% of body height); the reduction in muscle activities with SS use was 20% to 40%. Lowering the bed did not affect the SS effect magnitude on reducing muscle activities, although postural changes, including hip and knee joint flexion, were observed.

CONCLUSIONS/APPLICATION TO PRACTICE

SS reduced muscle activities in the back, upper, and lower extremities when the bed was in the low position, and this effect persisted at a bed height of ≥30% of the participant's height.

Development and evaluation of a new assistive device for low back load reduction in caregivers: an experimental study

Low back pain among healthcare professionals is associated with the manual handling of patients. Some bed features for turning and repositioning have been developed; however, the load during patient care remains heavy. We developed a device to reduce low back load in caregivers during patient bedside care and evaluated it objectively and subjectively from a caregiver's perspective using a randomised crossover study. Overall, 28 clinical nurses and care workers were randomly assigned to two interventional groups: administering care with (Device method) and without (Manual method) the device in an experimental room. We measured the caregiver's trunk flexion angle using inertial measurement units and video recording during care and then defined a trunk flexion angle of > 45° as the threshold; the variables were analysed using linear mixed models. Subsequently, participants responded to a survey regarding the usability of the device. Trunk flexion time and percentage of time were 26.5 s (95% confidence interval: 14.1 s, 38.9 s) (p < 0.001) and 23.0% (95% confidence interval: 16.4%, 29.6%) (p < 0.001) lower, respectively, in the Device group than in the Manual group. Furthermore, caregivers evaluated the care they could administer with the device as being better than that associated with manual care.

The effects of patient transfer devices on the risk of work-related musculoskeletal disorders (WMSDs): a systematic review

Objectives. This study aimed to evaluate the efficacy of patient transfer assistive devices in reducing the risk of work-related musculoskeletal disorders (WMSDs) among nurses. Methods. PubMed, Scopus, Google Scholar and the Cochrane Database of Systematic Reviews were searched to identify studies with a quantitative assessment of the efficacy of patient transfer assistive devices on the incidence and injury claims of WMSDs as compared to the manual lifting of patients. A health impact analysis of the pre-post intervention of assistive device implementation was performed. The percentage of the reduction of forces, incidence of WMSDs, number of missed workdays and injury compensation claims were calculated, pooled and presented as boxplots. Results. A total of 25 studies met the inclusion criteria. The best post-intervention outcomes of assistive devices deployment in the healthcare setting included a reduction in WMSD incidence by 59.8%, missed workdays by 90.0% and workers' compensation claims by 95.0%. Additionally, hand force declined by 71% (p < 0.05) and 70% (p < 0.05) with the use of air-assisted devices and ceiling lifts respectively. Conclusions. Overall, the evidence suggests that patient transfer assistive devices, notably ceiling lifts and air-assisted devices, are effective in reducing the risk of WMSDs among nurses.

The influence of organizational factors, eldercare worker characteristics and care situation on the use of assistive devices during resident handling in eldercare work

We evaluated the influence of organization, eldercare worker and care situation on the use of assistive devices during resident handling in eldercare work. We conducted a multi-level study among 20 nursing homes, 126 wards within the nursing homes, 549 eldercare workers within the wards, who performed a total of 1306 care episodes including 3695 resident handlings. The influence of organization (i.e. nursing home and ward), eldercare worker and care situation (i.e. care episode and resident handling) on the use of assistive devices was evaluated using variance components analysis and multivariate generalized linear mixed model. Nursing homes, wards, eldercare workers, care episodes and 'within care episode' all contributed to the total variance in use of assistive devices. Organizational factors and care situation factors were significantly associated with use of assistive devices. All levels of the nursing homes, but in particular care situation, influence the use of assistive devices during resident handling.
