Development and validation of an easy-to-use risk assessment tool for cumulative low back loading
The Lifting Fatigue Failure Tool (LiFFT) Recent evidence suggests that musculoskeletal disorders (MSDs) may be the result of a fatigue failure process in affected tissues. This paper describes a new low back exposure assessment tool (the Lifting Fatigue Failure Tool [LiFFT]), which estimates a “daily dose” of cumulative loading on the low back using fatigue failure principles. Only three variables are necessary to derive the cumulative load associated with a lifting task: the weight of the load, the maximum horizontal distance from the spine to the load, and the number of repetitions...
Initial Results of an Evidence-Based Safe Patient Handling and Mobility Program to Decrease Hospital Worker Injuries
The rate for musculoskeletal injuries among health care workers is one of the highest for all industrial sectors in the United States; these injuries often occur during manual handling (i.e., lifting, moving, transferring, and repositioning) of patients. The following article describes the process used to complete a comprehensive assessment, as well as the planning, implementation, and initial evaluation of a quality improvement program to reduce work-related musculoskeletal disorders (WMSD) among health care workers employed by a rural Midwest hospital. Key elements for WMSD injury reduction were...
Pushing and pulling: An assessment tool for OHS practitioners
A tool has been developed for supporting practitioners when assessing manual pushing and pulling operations based on an initiative by two global companies in the manufacturing industry. The aim of the tool is to support occupational health and safety practitioners in risk assessment and risk management of pushing and pulling operations in the manufacturing and logistics industries. It is based on a nine-multiplier equation that includes a wide range of factors affecting an operator's health risk and capacity in pushing and pulling. These multipliers are based on psychophysical, physiological...
A multi-component patient-handling intervention improves attitudes and behaviors for safe patient handling and reduces aggression experienced by nursing staff
A controlled before-after study This study evaluated an intervention for patient-handling equipment aimed to improve nursing staffs' use of patient handling equipment and improve their general health, reduce musculoskeletal problems, aggressive episodes, days of absence and work-related accidents. As a controlled before-after study, questionnaire data were collected at baseline and 12-month follow-up among nursing staff at intervention and control wards at two hospitals. At 12-month follow-up, the intervention group had more positive attitudes towards patient-handling equipment and increased...
Musculoskeletal Injury Prevention for New Nurses
Nurses continue to sustain musculoskeletal injuries even with increased emphasis on safe patient handling and mobility (SPHM) and organizational cultures of safety to protect health care workers. Analysis of data from 2011-2014 registered nurse graduates explored hospital safety culture, SPHM education/training, and incidence of new-nurse musculoskeletal injury. Results indicated hospitals provided some type of SPHM education and training, but 46% of study participants were not informed or aware of national SPHM standards or guidelines. Merely 13.9% of participants stated a written “no manual...
Ischaemic heart disease among workers in occupations associated with heavy lifting
OBJECTIVES: To investigate a hypothesized positive association between employment in occupations where heavy lifting is likely to occur, and the risk of ischaemic heart disease (IHD). MATERIAL AND METHODS: Male blue-collar workers from Denmark (N = 516 180) were monitored with respect to hospital treatment or death due to IHD, through national registers over the years 2001-2010. Poisson regression was used to estimate relative rates of IHD between "workers in occupations which, according to an expert opinion, are likely to involve heavy lifting" and "other blue-collar workers."...

Objectives : This study compared the cost efficiency of observation and inclinometer assessment of trunk and upper-arm inclination in a population of flight baggage handlers, as an illustration of a general procedure for addressing the trade-off between resource consumption and statistical performance in occupational epidemiology. Methods : Trunk and upper-arm inclination with respect to the line of gravity were assessed for three days on each of 27 airport baggage handlers using simultaneous inclinometer and video recordings. Labor and equipment costs associated with data collection and processing...
Patient transfers and assistive devices
Prospective cohort study on the risk for occupational back injury among healthcare workers Objectives : This prospective cohort study investigates work-related risk factors for occupational back injury among healthcare workers. Methods : The study comprised 5017 female healthcare workers in eldercare from 36 municipalities in Denmark who responded to a baseline and follow-up questionnaire in 2005 and 2006, respectively. Using logistic regression, the odds for occupational back injury (ie, sudden onset episodes) in 2006 from patient transfers in 2005 was modeled. Results : In the total study population...
Paramedics on the job
Dynamic trunk motion assessment at the workplace Many paramedics' work accidents are related to physical aspects of the job, and the most affected body part is the low back. This study documents the trunk motion exposure of paramedics on the job. Nine paramedics were observed over 12 shifts (120 h). Trunk postures were recorded with the computer-assisted CUELA measurement system worn on the back like a knapsack. Average duration of an emergency call was 23.5 min. Sagittal trunk flexion of >40° and twisting rotation of >24° were observed in 21% and 17% of time-sampled postures...
Occupation, participation, inclusion, work role Postural control in different load handling tasks
BACKGROUND : Manual material handling has been attributed as a major risk to human musculoskeletal system. Workers postural stability in these tasks is influenced by holding method, time and weight being handled. OBJECTIVES : The study attempts to investigate postural balance in five different commonly adopted load handling methods amongst female volunteers. METHODS : 10 women subjects performed manual material handling tasks by lifting 9 kg load in five different ways. Lifting tasks included (1) Upfront in palms (2) on head (3) sideways (left) (4) sideways (right) and (5) in bag at back. Normalized...
Impacts biomécaniques et ergonomiques de la manutention chez les travailleurs obèses
L’obésité est un problème émergent qui semble s’immiscer dans les problématiques de santé et sécurité du travail. La prévalence de blessures musculo-squelettiques chez les individus obèses et les coûts indirects (non médicaux) sont plus élevés que ceux des travailleurs ayant un poids santé. Sachant qu’une hausse soutenue du taux d’obésité chez les travailleurs est observée au Canada, il est important de s’intéresser à la problématique...
Ceiling Lifts: Why Aren't They Being Used?
Using ceiling lifts to transfer, reposition, and turn clients reduces injuries. Sometimes though, even when lifts are available, they're not always used. This video challenges the seven most common reasons health care workers give for not using ceiling lifts. Source : http://www2.worksafebc.com/Publications/Multimedia/Videos.asp?ReportID=37077
Risk of neck musculoskeletal disorders among males and females in lifting exertions
Work-related neck disorders are common among various occupational groups. Despite clear epidemiological evidence for the association of these disorders with forceful arm exertions, the effect of such exertions on the biomechanical behavior of the neck muscles is currently not well understood. In this study, the effect of lifting tasks on the biomechanical loading of neck muscles was investigated for males and females. Twenty-six participants (13 males and 13 females) performed bi-manual isometric lifting tasks at knuckle, elbow, shoulder, and overhead heights by exerting 25%, 50%, and 75% of their...
Long-Term Efficacy of an Ergonomics Program That Includes Patient-Handling Devices on Reducing Musculoskeletal Injuries to Nursing Personnel
Objective: The aim of this study was to evaluate long-term efficacy of an ergonomics program that included patient-handling devices in six long-term care facilities (LTC) and one chronic care hospital (CCH). Background: Patient handling is recognized as a major source of musculoskeletal disorders (MSDs) among nursing personnel, and several studies have demonstrated effectiveness of patient-handling devices in reducing those MSDs. However, most studies have been conducted in a single facility, for a short period, and/or without a comprehensive ergonomics program. Method: Patient-handling devices...
Musculoskeletal injuries among hospital patient care staff before and after implementation of patient lift and transfer equipment
Objective: Using an observational research design and robust surveillance data, we evaluated rates of musculoskeletal (MS) injuries, days away from work, and restricted work days among patient care staff at a medical center and community hospital in the United States over 13 years, during which time a “minimal manual lift” policy and mechanical lift equipment were implemented. Methods: Workers’ compensation claims data were linked to human resources data to define outcomes of interest and person-time at risk to calculate rates. Poisson and negative binomial regression with lagging...
Practical Demonstrations of Ergonomic Principles
Musculoskeletal disorders (MSDs) often involve the back, wrist, elbow, and/or shoulder, and occur when workers are exposed over time to MSD risk factors, such as awkward postures, forceful exertions, or repetitive motions. These exposures sometimes occur due to poorly designed workstations, tasks, and/or hand tools [Chaffin et al. 2006; Sanders and McCormick 1993; Silverstein et al. 1996, 1997]. Workers must understand the nature of MSD risk factors and how to avoid exposure to them. In a classroom setting, trainers may discuss ergonomic principles and show examples of MSD risk factors with photographs...
