Musculoskeletal symptoms among hospital cleaners

Global prevalence of musculoskeletal disorders among sanitary workers: a systematic review and meta-analysis

Objectives. Sanitary workers are more likely to experience musculoskeletal disorders (MSDs) due to a lack of ergonomics principles and poor job design. Thus, this systematic review and meta-analysis aimed to quantify MSDs among sanitary workers. Methods. The PRISMA and PICOS protocols were used for flow diagrams and review questions, respectively. Articles published between 2000 and 2022 were eligible. The keywords '(Musculoskeletal Disorders) AND (Solid waste collectors *OR Street sweepers *OR Sewage workers *OR health facilities cleaners)' and MeSH terms were utilized. The data were analyzed using STATA version 17 with a 95% confidence interval (CI). Results. A total of 158 papers were qualified, with 26 studies from 17 countries and a total of 6586 sanitary workers. The global prevalence of MSDs among sanitation workers was 40.52% (95% CI [32.47, 48.67]; p < 0.05). It was 43.32% (95% CI [31.98, 54.68]; p < 0.05) in high-income countries and 38.58% (95% CI [26.94, 50.18]; p < 0.05) in low-income countries. By subgroup analysis, it was 45.12% (95% CI [32.57, 57.67]; p < 0.05) for solid waste collectors, which is the highest prevalence among other workers. Conclusion. Current evidence shows that sanitation workers have a higher prevalence of occupationally associated MSDs, which might be lowered by using ergonomic work design principles.

Physical Ergonomic Assessment in Cleaning Hospital Operating Rooms Based on Inertial Measurement Units

Workers involved in hospital operating room cleaning face numerous constraints that may lead to musculoskeletal disorders. This study aimed to perform physical ergonomic assessments on hospital staff by combining a continuous assessment (RULA) based on inertial measurement units with video coding. Eight participants performed cleaning tasks while wearing IMUs and being video recorded. A subjective evaluation was performed through the Nordic questionnaire. Global RULA scores equaled 4.21 ± 1.15 and 4.19 ± 1.20 for the right and left sides, respectively, spending most of the time in the RULA range of 3-4 (right: 63.54 ± 31.59%; left: 64.33 ± 32.33%). Elbows and lower arms were the most exposed upper body areas with the highest percentages of time spent over a risky threshold (right: 86.69 ± 27.27%; left: 91.70 ± 29.07%). The subtask analysis identified 'operating table moving', 'stretcher moving', and 'trolley moving' as the riskiest subtasks. Thus, this method allowed an extensive ergonomic analysis, highlighting both risky anatomical areas and subtasks that need to be reconsidered.

Cleaning in the 21st Century: The musculoskeletal disorders associated with the centuries-old occupation - A literature review

Workers performing cleaning duties experience higher injury rates, especially in the form of musculoskeletal disorders (MSDs), than other industries. It is essential to understand the inherent risks associated with the nature of this occupation. Based on the Balance Theory (Smith & Carayon-Sainfort, 1989), this review surveys the current literature, especially those published since the previous review paper (Kumar & Kumar, 2008), and identifies which elements contributing to MSD risks were examined: task, technology, organization, environment, individual, and their interactions. Thirty-nine research papers published between 2005 and 2021 are identified and summarized. Among these papers, task and individual elements received the most attention, at 42 and 34 occurrences, respectively. The interaction elements of technology-organization, technology-environment, and organization-environment received less than three mentions. The goal of this literature review is to update the knowledge base and identify current trends for the cleaning occupation. Possible interventions for risk reduction and future research directions are suggested.

Musculoskeletal disorders among the population in Northwest Ethiopia

Objective:

This study aimed to assess the magnitude and patterns of chronic musculoskeletal disorders among the population in East Gojjam zone, Northwest Ethiopia.

Methods:

A community-based cross-sectional study with 846 recruited study participants was done using a multistage sampling technique in conjunction with a simple and systematic random sampling technique. Face-to-face interviews, physical examinations, a semi-structured questionnaire adapted from the Community Oriented Program for Control of Rheumatic Diseases, and other literature were used to collect data. EpiData 3.1 was used to enter the data, which were then exported to STATA 14.0 for analysis.

Result:

The study had a response rate of 98.8%, with about 836 people out of a total of 846 expected to take part. The magnitude of musculoskeletal disorders was found to be 40.1%. Back pain was the most common musculoskeletal condition (16%) of the population, followed by osteoarthritis (10%) and other forms of arthritis (rheumatoid arthritis (8%), gout arthritis (6%)). The most common comorbidity (multimorbidity) patterns were hypertension (9.8%), diabetes (5.6%), obesity (3.9%), and others (2.2%).

Conclusion:

Almost one in four participants have at least one musculoskeletal disorder in Northwest Ethiopia. Rheumatoid arthritis, osteoarthritis, low back pain, and gout arthritis were the most common musculoskeletal disorders. The most common comorbidity patterns were hypertension, diabetes, obesity, and others. An in-depth investigation of the musculoskeletal burden at the national level will be critical for implementing evidence-based strategies, as well as early detection and screening, linking to health institutions, and direct interventions.

Prevalence and Associated Factors of Musculoskeletal Disorders Among Cleaners Working at Mekelle University, Ethiopia

Background

Musculoskeletal disorder is a common cause of morbidity, disability, and poor quality-of-life. Its burden among cleaners in developed countries ranges from 56–90%. However, there are a lack of studies in developing countries, particularly in the study area. Thus, the result of this study will help to resolve health problems caused by musculoskeletal disorders among cleaners.

Purpose

The objective of this study was to identify the prevalence and associated factors of musculoskeletal disorders among cleaners working at Mekelle University.

Materials and Methods

An institutional-based cross-sectional study was conducted on 270 cleaners. Simple random sampling was used to select the study participants. Data were collected through interview using the standard Nordic Musculoskeletal Questionnaire. Descriptive statistics and bivariate logistic regression were done to identify factors associated with musculoskeletal disorder. In bivariate logistic regression analysis, variables with a P-value<0.25 were modeled to multivariate analysis. Variables with a P-value≤0.05 with 95% confidence interval (CI) in multivariate model were taken as statistically significant. Finally, AOR with 95% CI at a P-value<0.05 was reported.

Results

This study found that the prevalence of musculoskeletal disorders among cleaners was 52.3% in the past 12 months and 31.8% in the last 7 days. Time pressure (AOR=3.25, 95% CI=1.08–9.77), work experience (AOR=2.49, 95% CI=1.12–5.52), feeling exhausted (AOR=2.68, 95% CI=1.16–6.20), working hours per day (AOR=3.55, 95% CI=1.54–8.20), awkward posture (AOR=15.71, 95% CI=6.47–38.17), and those who work more than 2 hours in sustaining position (AOR=8.05, 95% CI=2.25–28.85) showed a statistically significant association with musculoskeletal disorder.

Conclusion

Musculoskeletal disorders were commonly reported among cleaners working at Mekelle University. Time pressure, work experience, feeling exhausted, working hours per day, awkward posture, and working >2 hours in sustaining position were statistically significant in their association with musculoskeletal disorders.

Work-related risk factors and the prevalence of low back pain among low wage workers: results from a cross-sectional study

Background

Low back pain, the most commonly reported musculoskeletal problem, is a major burden on individuals, health systems and social care systems with the indirect cost being predominant. It results in disability, poor service, low quality of life and sickness absences in working places. The problem of low back pain and its risk factors among hotel housekeepers are not well known in Ethiopia. Therefore, this study was aimed to investigate the prevalence and identify determinants of low back pain among hotel industries’ housekeepers in Gondar town, Ethiopia.

Methods

Institutional based cross-sectional study was conducted from March to May 2017. A systematic random sampling technique was applied to select 422 study participants, and the data was collected by a standardized Nordic questionnaire for the analysis of musculoskeletal symptoms. Bivariate and multivariable binary logistic regression analyses were performed using SPSS version 20. The significance level was obtained at 95% CI and p-value ≤ 0.05.

Results

The prevalence of low back pain among hotel housekeepers in Gondar town was 58.1% (95% CI: 53.6, 62.8%). Being temporary employee (AOR: 3.22), type of job which requires reaching/overstretching (AOR: 2.93), engaging in a job that requires repetitive bending (AOR: 1.97), making > 30 beds per day (AOR: 3.19) signified the significant risk factors for low back pain. However, hotel housekeepers who were satisfied in their current job were less impacted by low back pain (AOR: 0.49).

Conclusion

A high proportion of hotel housekeepers in this study reported they had low back pain. Employment pattern, rest break taken, reaching/overstretching, repetitive bending, job satisfaction, training related to health and safety and numbers of beds making were among the factors associated with low back pain. Hence, ergonomic measures focusing on correcting the arrangement of work station, rest breaks and changing some equipment are potentially important targets to reduce the problem.
